    Women with Neck Pain on Long-Term Sick Leave — Approaches Used in the Return to Work Process: A Qualitative Study2016In: Journal of occupational rehabilitation, ISSN 1053-0487, E-ISSN 1573-3688, p. 1-14Article in journal (Refereed)
    Abstract [en]

    Purpose There are difficulties in the process of return to work (RTW) from long-term sick leave, both in general and regarding sick leave because of neck pain in particular. Neck pain is difficult to assess, problematic to rehabilitate, and hard to cure; and it is not always easy to decide whether the pain is work-related. The outcome of RTW could be dependent upon individuals’ approaches, defensive or offensive behaviors, and choices related to their self-efficacy. The aim of this study was to identify approaches used in the RTW process among women with neck pain on long-term sick leave from human service organizations. Methods This is a qualitative descriptive study based on grounded theory. A Swedish cohort of 207 women with a history of long-term sick leave with neck pain from human service organizations answered open-ended written questions at 0, 6, and 12 months, and 6 years; and 16 women were interviewed. Results Individuals expressed their coping approaches in terms of fluctuating in work status over time: either as a strategy or as a consequence. Periods of sick leave were interwoven with periods of work. The women were either controlling the interaction or struggling in the interaction with stakeholders. Conclusions Return to work outcomes may be improved if the fluctuating work status over time is taken into account in the design of rehabilitation efforts for women with a history of long-term sick leave and with chronical musculoskeletal conditions.

    Return to work from long-term sick leave: a five-year prospective study of the importance of adjustment latitudes at work and home2014Conference paper (Other academic)
    Abstract [en]

    Background

    Adjustment latitude among employees, i.e. adjusting work to individual’s health capacity, has been associated with successful return to work (RTW) in cross-sectional studies. The aim is to investigate the long-term importance of adjustment latitude at the workplace and at home, as well as attitudes (own and colleagues) for increased work ability (WA), working degree (WD) and health-related quality of life (HRQoL) among female human service workers (HSW) on long-term sick leave in Sweden.

    Methods

    A cohort of female HSW (n=324) on long-term sick leave (>60 day) received a questionnaire at four times (0, 6, 12, 60 months). Prevalence ratios (PR) were used to examine possible relationships between explanatory factors and outcomes. Linear mixed models were used for longitudinal analysis of the repeated measurements of WA Score (0-10), WD (0-100%) and HRQoL (0-100). Analyses were performed with different models; the explanatory variables for each model were adjustment latitude, attitudes towards breaks at work, shared or single household and amount of household work.

    Result

    Having more adjustment latitude at work was associated with both increased WA and RTW compared to having few adjustment latitude opportunities. Adjustments related to working-pace were strongly associated with increased WD (PR 3.29(95%CI=1.71-6.26)), as were adjustments to working-place. Having opportunities to take short breaks at work, and a general acceptance at work to take short breaks was associated with increased WA. At home, a higher responsibility for household work (PR 1.98(95%CI=1.33-2.95)) was related to increased WA and RTW. Individuals with possibilities for adjustment latitude, especially pace and place, at work, and an acceptance to take breaks at work, increased in WA score significantly more over time and had higher WA score compared with individuals not having such opportunities at work. These prospective results were similar for the outcome WD and HRQoL.

    Conclusions

    The results highlight the importance of possibilities for adjustment latitude at work and at home, as well as accepting attitudes to take short breaks to increase WA and RTW among female human service workers previously on long-term sick leave.

    A Novel Method to Intelligently Mine Social Media to Assess Consumer Sentiment of Pharmaceutical Drugs2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis focuses on the development of novel data mining techniques that convert user interactions in social media networks into readable data that would benefit users, companies, and governments. The readable data can either warn of dangerous side effects of pharmaceutical drugs or improve intervention strategies. A weighted model enabled us to represent user activity in the network, that allowed us to reflect user sentiment of a pharmaceutical drug and/or service. The result is an accurate representation of user sentiment. This approach, when modified for specific diseases, drugs, and services, can enable rapid user feedback that can be converted into rapid responses from consumers to industry and government to withdraw possibly dangerous drugs and services from the market or improve said drugs and services.

    Our approach monitors social media networks in real-time, enabling government and industry to rapidly respond to consumer sentiment of pharmaceutical drugs and services.

    A novel data-mining approach leveraging social media to monitor and respond to outcomes of diabetes drugs and treatment2013In: 2013 IEEE Point-of-Care Healthcare Technologies (PHT), New York: IEEE , 2013, p. 264-266Conference paper (Refereed)
    Abstract [en]

    A novel data-mining method was developed to gauge the experiences of medical devices and drugs by patients with diabetes mellitus. Self-organizing maps were used to analyze forum posts numerically to better understand user opinion of medical devices and drugs. The end-result is a word list compilation that correlates certain positive and negative word cluster groups with medical drugs and devices. The implication of this novel data-mining method could open new avenues of research into rapid data collection, feedback, and analysis that would enable improved outcomes and solutions for public health.

    A Novel Data-Mining Approach Leveraging Social Media to Monitor Consumer Opinion of Sitagliptin2015In: IEEE journal of biomedical and health informatics, ISSN 2168-2194, E-ISSN 2168-2208, Vol. 19, no 1, p. 389-396Article in journal (Refereed)
    Abstract [en]

    A novel data mining method was developed to gauge the experience of the drug Sitagliptin (trade name Januvia) by patients with diabetes mellitus type 2. To this goal, we devised a two-step analysis framework. Initial exploratory analysis using self-organizing maps was performed to determine structures based on user opinions among the forum posts. The results were a compilation of user's clusters and their correlated (positive or negative) opinion of the drug. Subsequent modeling using network analysis methods was used to determine influential users among the forum members. These findings can open new avenues of research into rapid data collection, feedback, and analysis that can enable improved outcomes and solutions for public health and important feedback for the manufacturer.

    Abstract [en]

    A novel data-mining method was developed to gauge the experiences of the diabetes mellitus drug Januvia. Self-organizing maps were used to analyze forum posts numerically to infer user opinion of drug Januvia. Graph theory was used to discover influential users. The result is a word list compilation correlating positive and negative word cluster groups and a web of influential users on Januvia. The implications could open new research avenues into rapid data collection, feedback, and analysis that would enable improved solutions for public health.

    Network-Based Modeling and Intelligent Data Mining of Social Media for Improving Care2015In: IEEE journal of biomedical and health informatics, ISSN 2168-2194, E-ISSN 2168-2208, Vol. 19, no 1, p. 210-218Article in journal (Refereed)
    Abstract [en]

    Intelligently extracting knowledge from social media has recently attracted great interest from the Biomedical and Health Informatics community to simultaneously improve healthcare outcomes and reduce costs using consumer-generated opinion. We propose a two-step analysis framework that focuses on positive and negative sentiment, as well as the side effects of treatment, in users' forum posts, and identifies user communities (modules) and influential users for the purpose of ascertaining user opinion of cancer treatment. We used a self-organizing map to analyze word frequency data derived from users' forum posts. We then introduced a novel network-based approach for modeling users' forum interactions and employed a network partitioning method based on optimizing a stability quality measure. This allowed us to determine consumer opinion and identify influential users within the retrieved modules using information derived from both word-frequency data and network-based properties. Our approach can expand research into intelligently mining social media data for consumer opinion of various treatments to provide rapid, up-to-date information for the pharmaceutical industry, hospitals, and medical staff, on the effectiveness (or ineffectiveness) of future treatments.

    Assessing Antidepressants Using Intelligent Data Monitoring and Mining of Online Fora2016In: IEEE journal of biomedical and health informatics, ISSN 2168-2194, E-ISSN 2168-2208, Vol. 20, no 4, p. 977-986Article in journal (Refereed)
    Abstract [en]

    Depression is a global health concern. Social networks allow the affected population to share their experiences. These experiences, when mined, extracted, and analyzed, can be converted into either warnings to recall drugs (dangerous side effects), or service improvement (interventions, treatment options) based on observations derived from user behavior in depression-related social networks. Our aim was to develop a weighted network model to represent user activity on social health networks. This enabled us to accurately represent user interactions by relying on the data's semantic content. Our three-step method uses the weighted network model to represent user's activity, and network clustering and module analysis to characterize user interactions and extract further knowledge from user's posts. The network's topological properties reflect user activity such as posts' general topic as well as timing, while weighted edges reflect the posts semantic content and similarities among posts. The result, a synthesis from word data frequency, statistical analysis of module content, and the modeled health network's properties, has allowed us to gain insight into consumer sentiment of antidepressants. This approach will allow all parties to participate in improving future health solutions of patients suffering from depression.

    Mining Social Media Big Data for Health2015In: IEEE PulseArticle, review/survey (Refereed)
    Abstract [en]

    Advances in information technology (IT) and big data are affecting nearly every facet of the public and private sectors. Social media platforms are one example of such advances: its nature allows users to connect, collaborate, and debate on any topic with comparative ease. The result is a hefty volume of user-generated content that, if properly mined and analyzed, could help the public and private health care sectors improve the quality of their products and services while reducing costs. The users of these platforms are the key to these improvements, as their valuable feedback will help improve health solutions.

    Validation of an agent based model using a participatory simulation gaming approach: The case of city logistics2016In: Transportation Research Part C: Emerging Technologies, ISSN 0968-090X, E-ISSN 1879-2359, Vol. 71, p. 489-499Article in journal (Refereed)
    Abstract [en]

    Agent-based modeling is used for simulating the actions and interactions of autonomous entities aiming to assessing their effects on the system as a whole. At an abstract level, an agent-based model (ABM) is a representation of the many simple agents and interactions among them. The decision making of the agents is based on the rules given to them. In an ABM, the model output is the result of internal decision-making and may differ with alteration in the decision path. On the contrary, with the set of rules embedded in agents, their behavior is modeled to take a ‘certain action’ in a ‘certain situation’. It suggests that the internal decision making behavior of agents is truly responsible for the model output and thus it cannot be ignored while validating ABMs. This research article focuses on the validating agents’ behavior by evaluating decision-making processes of agents. For this purpose, we propose a validation framework based on a participatory simulation game. Using this framework we engage a human player (i.e. a domain stakeholder) to allow us to collect information about choices and validate the behavior of an individual agent. A proof-of-concept game is developed for a city logistics ABM to test the framework.

    Abstract [en]

    Lean has become the predominant management concept in industry, but its effect on the work environment is debated. Lean has now reached farms and garden nurseries. This paper aims to identify consequences for the physical and psychosocial work environment when Lean was applied in micro-businesses in the agricultural sector. Observations, a questionnaire and interviews were used as methods. It was concluded that the psychosocial work environment became more structured and less stressful. The physical work environment was partly improved by less transportation on the farm. However, consideration of the physical work environment was insufficient.

    Systematisk kunskapsbrist i skolan?: Arbetsmiljöarbete utan udd2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Swedish employers are obliged by law to systematically plan, direct and control activities so that the working environment meets the prescribed requirements. However, evidence indicates that this work is not performed satisfactorily in many schools. This case study aims at mapping out and clarifying how measures towards planning, directing and controlling activities are organized in two public compulsory schools.

     

    The overall purpose of the study is to shed light on elements and conditions that hinder a successful implementation of work environment measures. Our main research questions are: Does the way the municipalities have organized the working environment measures reach the requirements in the law and how controls and follow-ups are performed. Data was collected through the municipalities’ steering documents together with a survey in combination with follow-up interviews with key figures.

     

    Results show that the working environment measures in both schools are organized and performed in similar ways and that the problems reported to a large extent are the same. The unanimous picture shows an organization that is not capable of identifying and handling all important risks. Conclusions from the study indicate that there is a lack of knowledge concerning working environments measures on all levels in the organizations.

    Abstract [en]

    The open-plan offices at Boliden has been renovated. The company wanted an evaluation of what the employees thought about the physical work environment in the new offices. The company also wanted the study to present improvement for deficiencies in the physical environment.

     

    The aim of this study was to identify positive and negative aspects of the physical working environment factors and to identify correlation between the physical work environment factors and job satisfaction, productivity and stress. A second purpose was also to present some improvement for the physical work environment. A part of the questionnaire was to evaluate if there existed any difference between the sexes regarding the physical work environment. To examine these aspects this study used a questionnaire as well a system group seminar to develop possible improvements.

     

    The results from the questionnaire show that the employees were pleased with the ventilation, the furniture’s functionality and the aesthetics of the office. The questionnaire also found dissatisfaction with glare, outlook and temperature but mostly the audial privacy in the office.

     

    Previous studies have shown that there is a correlation between physical work environment factors, job satisfaction and productivity but inconsistent evidence for work environment and stress. This study showed significant relationship between the auditory privacy, job satisfaction and productivity but not between auditory privacy and stress, which corresponds to the previous studies.

     

    The improvements presented at the system group seminar was to introduce guidelines to reduce noise and divide the office into smaller offices. To improve the auditory privacy this study suggests that a combination of redeploying employees in the open-plan office, dividing the office in to smaller office areas and introduces guidelines of how the employees should behave in the open-plan office.

    The importance of healthcare managers’ organizational preconditions and support resources for their appraisal of planned change and its outcomes2017In: Journal of Hospital Administration, ISSN 1927-6990, E-ISSN 1927-7008, Vol. 6, no 1Article in journal (Refereed)
    Abstract [en]

    Background: Healthcare managers are expected to lead and manage planned organizational change intended to improve healthcare process quality. However, their complex working conditions offer limited decision control, and healthcare managers often feel ill prepared and inadequately supported to perform their duties. Healthcare managers have previously described their need for organizational support, but we lack knowledge of the preconditions and resources that help managers implement planned change.Methods: This prospective cohort study examined healthcare managers at three Swedish hospitals implementing lean production and two Swedish hospitals implementing their own improvement model. Questionnaire data from 2012, 2103, and 2014 were used in following up. We used t-tests and a linear mixed model design in analysing the data.Results: Healthcare managers who perceived strong support from managers, employees, colleagues, and the organization and managers with the longest managerial experience had the least negative appraisal of change. Managers who perceived strong support from employees, management, and the organizational structure perceived higher levels of healthcare process quality.Conclusions: Long managerial experience and strong support from managers, employees, and the organization are important formanagers’ appraisal of, work on, and successful implementation of planned change. Top management must therefore ensure that the healthcare managers have sufficient managerial experience and support before they delegate to them the responsibility to implement planned change.

    Health care managers' views on and approaches to implementing models for improving care processes2016In: Journal of Nursing Management, ISSN 0966-0429, E-ISSN 1365-2834, Vol. 24, no 2Article in journal (Refereed)
    Abstract [en]

    Aim: To develop a deeper understanding of health-care managers' views on and approaches to the implementation of models for improving care processes. Background: In health care, there are difficulties in implementing models for improving care processes that have been decided on by upper management. Leadership approaches to this implementation can affect the outcome. Method: In-depth interviews with first- and second-line managers in Swedish hospitals were conducted and analysed using grounded theory. Results: 'Coaching for participation' emerged as a central theme for managers in handling top-down initiated process development. The vertical approach in this coaching addresses how managers attempt to sustain unit integrity through adapting and translating orders from top management. The horizontal approach in the coaching refers to managers' strategies for motivating and engaging their employees in implementation work. Conclusion and implications for nursing management: Implementation models for improving care processes require a coaching leadership built on close manager-employee interaction, mindfulness regarding the pace of change at the unit level, managers with the competence to share responsibility with their teams and engaged employees with the competence to share responsibility for improving the care processes, and organisational structures that support process-oriented work. Implications for nursing management are the importance of giving nurse managers knowledge of change management.

    Abstract [en]

    This chapter reports on the work activities, time-use patterns, and stress patterns of ten health care managers in Sweden. The qualitative and quantitative evidence reveals the fragmentation in their nine-hour working days where each activity, on average, lasts only ten minutes. The time-use patterns vary individually though some patterns are related to position and unit type. Activities deal with the coexisting and competing logics of employeeship, administration, and strategy and risk handling. None of the managers’ approaches for handling the multiple legitimation processes and delimiting their workload boundaries really challenges the complexity of the coexistence of the multiple logics or the boundlessness of their working hours. Using biophysical measures, the research finds that stress reported by the managers is caused by (a) interruptions during challenging tasks and (b) personal situations such as private dilemmas and conflict-loaded or ineffective meetings. It is important to acknowledge managers’ fragmented working situation and to recognize that management should be seen as collective process, or as part of an administrative system.

    Modeling network controller decisions based upon situation awareness through agent-based negotiation2014In: 44th International Simulation and Gaming Association Conference, ISAGA 2013 and 17th IFIP WG 5.7 Workshop on Experimental Interactive Learning in Industrial Management, Springer-Verlag Tokyo Inc., 2014, p. 191-200Conference paper (Refereed)
    Abstract [en]

    The Dutch railway traffic control is in an urgent need for innovation and therefore turns to gaming simulation as a platform to test and train future configurations of the system. The presence of relevant participants is necessary to keep the fidelity of the gaming simulation high. Network controllers are often needed in such games, but are expensive, scarce, and often have limited action, thus making their involvement less than desirable. To overcome this, the current paper introduces the use of intelligent software agents to replace some roles. The cognitive construct of situation awareness is required to model the evaluation of an offer in a negotiation setting, in which a situation awareness model (SAM) is introduced for evaluating offers in complex and dynamic systems.

    Abstract [en]

    Transportation Planners have a long history of using Geographical Information Systems, Simulation Models and Visualizations for decision support. A frame-work that integrates all three can provide enhanced decision support, opportuni-ties for training and planning future scenarios. In the current paper, we describe the concept of such a framework and the first steps toward its development.

    Lean Implementation: the significance of people and dualism2013Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Lean, with its origins at the Toyota Motor Company, is a concept that is known to increase effectiveness in manufacturing. The Lean concept is now argued to be relevant not only in manufacturing but in service and health-care delivery as well. The reported results of Lean implementation efforts are divided. There are reports that most of the Lean implementation efforts are not reaching the goal; on the other hand, there are reports of promising results. The divided results from Lean implementation efforts show how important it is to research and identify factors that are barriers to successful implementation of Lean. This thesis aims to contribute knowledge about barriers to Lean implementation by collecting empirical findings from manufacturing and health care and structuring the perceived barriers and difficulties to Lean implementation. My first study aimed to compare similarities and divergences in barriers to Lean described by key informants in manufacturing and health care. The data was collected via semi-structured interviews. Findings showed that the perceived difficulties and barriers are much the same in manufacturing and health care. The second study was a case study at a manufacturing firm, researching how the views on Lean of the managers implementing Lean influence its implementation. Data was collected via semi-structured interviews with 20 individuals and covered all hierarchical management levels in the company. Findings showed that managers' views on Lean influence the implementation but also that learning during the implementation process can alter managers' views of Lean. The third study aimed to research how management of Lean is described in the literature. This was done through a literature review. The findings showed that Lean management is a matter of dualism, consisting of two complementary systems of action, management and leadership, which are related to the two basic principles of Lean, continuous improvement and respect for the people.

    Exploring communication processes in workplace meetings: A mixed methods study in a Swedish healthcare organization2016In: Work: A journal of Prevention, Assesment and rehabilitation, ISSN 1051-9815, E-ISSN 1875-9270, Vol. 54, no 3, p. 533-541Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: An efficient team and a good organizational climate not only improve employee health but also the health and safety of the patients. Building up trust, a good organizational climate and a healthy workplace requires effective communication processes. In Sweden, workplace meetings as settings for communication processes are regulated by a collective labor agreement. However, little is known about how these meetings are organized in which communication processes can be strengthened. OBJECTIVE: The aim of this study was to explore communication processes during workplace meetings in a Swedish healthcare organization. METHODS: A qualitatively driven, mixed methods design was used with data collected by observations, interviews, focus group interviews and mirroring feedback seminars. Data were analyzed using descriptive statistics and conventional content analysis. RESULTS: The communication flow and the organization of the observed meetings varied in terms of physical setting, frequency, time allocated and duration. The topics for the workplace meetings were mainly functional with a focus on clinical processes. Overall, the meetings were viewed not only as an opportunity to communicate information top down but also a means by which employees could influence decision-making and development at the workplace. CONCLUSIONS: Workplace meetings have very distinct health-promoting value. It emerged that information and the opportunity to influence decisions related to workplace development are important to the workers. These aspects also affect the outcome of the care provided.

    Exploring the usability of a videophone mock-up for persons with dementia and their significant others2014In: BMC Geriatrics, ISSN 1471-2318, E-ISSN 1471-2318, Vol. 14, p. 49-Article in journal (Refereed)
    Abstract [en]

    Background: Persons with dementia might have considerable difficulties in using an ordinary telephone. Being able to use the telephone can be very important in order to maintain their social network, getting stimulation and for reaching help when needed. Therefore, persons with dementia might need an easy-to-use videophone to prevent social isolation and to feel safe and independent. This study reports the evaluation of the usability of a touch-screen videophone mock-up for persons with dementia and their significant others. Methods: Four persons with dementia and their significant others tested the videophone mock-up at a living laboratory. In order to gain knowledge of the participants' with dementia ability to use their own computers and telephones, interviews and observations were conducted. Results: Overall, the participants had a very positive attitude towards the videophone. The participants with dementia perceived that it was useful, enjoyable and easy to use, although they initially had difficulties in understanding how to handle some functions, thus indicating that the design needs to be further developed to be more intuitive. Conclusions: The findings suggest that the videophone has the potential to enable telephone calls without assistance and add quality in communication.

    Development of evidence-based practice in occupational health services in Sweden: a 3-year follow-up of attitudes, barriers and facilitators2017In: International Archives of Occupational and Environmental Health, ISSN 0340-0131, E-ISSN 1432-1246, Vol. 90, no 4, p. 335-348Article in journal (Refereed)
    Abstract [en]

    The Swedish government initiated an investigation of how to secure and develop the competence of the occupational health services. The primary aim of the present study was to investigate whether the development of evidence-based practice (EBP) in the Swedish occupational health services in relation to attitudes, knowledge and use improved during the first 3 years of the government's initiative. The study has a mixed methods design combining questionnaires and interviews with data collection at baseline and at 3-year follow-up. The response rate was 66% at baseline and 63% at follow-up. The results show that practitioners' knowledge of EBP was moderate at baseline and improved at follow-up (p = 0.002; 95% CI 0.01; 0.21). Practitioners experienced lower levels of organizational and managerial support for EBP at follow-up (p < 0.001; 95% CI 0.18; 0.38). The results revealed that managers viewed responsibility for implementing EBP as a matter for individual practitioners rather than as an organizational issue. Occupational health service managers and practitioners are generally positive to EBP. However, the findings emphasize the need to educate managers in how to support EBP at the organizational level by creating an infrastructure for EBP in the OHS.

    Being a pedestrian with dementia: A qualitative study using photo documentation and focus group interviews2016In: Dementia, ISSN 1471-3012, E-ISSN 1741-2684, Vol. 15, no 5, p. 1124-1140Article in journal (Refereed)
    Abstract [en]

    The aim of the study was to identify problematic situations in using zebra crossings. They were identified from photo documentations comprising film sequences and the perspectives of people with dementia. The aim was also to identify how they would understand, interpret and act in these problematic situations based on their previous experiences and linked to the film sequences. A qualitative grounded theory approach was used. Film sequences from five zebra crossings were analysed. The same film sequences were used as triggers in two focus group interviews with persons with dementia. Individual interviews with three informants were also performed. The core category, the hazard of meeting unfolding problematic traffic situations when only one layer at a time can be kept in focus, showed how a problematic situation as a whole consisted of different layers of problematic situations. The first category, adding layers of problematic traffic situations to each other, was characterized by the informants' creation of a problematic situation as a whole. The different layers were described in the subcategories of layout of streets and zebra crossings, weather conditions, vehicles and crowding of pedestrians. The second category, actions used to meet different layers of problematic traffic situations, was characterized by avoiding problematic situations, using traffic lights as reminders and security precautions, following the flow at the zebra crossing and being cautious pedestrians. In conclusion, as community-dwelling people with dementia commonly are pedestrians, it is important that health care professionals and caregivers take their experiences and management of problematic traffic situations into account when providing support.

    Leaninspirerade förändringar och personalens upplevelser2013In: Lean i arbetslivet / [ed] Sederblad, Per, Stockholm: Liber, 2013, 1, p. 103-121Chapter in book (Other academic)
    Abstract [sv]

    De anställdas upplevelser av hur de kommer att påverkas av ett förändringskoncept är en avgörande faktor för om konceptet kommer att få reellt genomslag eller inte. Det här kapitlet behandlar denna centrala aspekt av leankonceptet – hur personalen upplever leaninspirerade förändringar. Just denna fråga finns det mycket lite empirisk forskning kring, så väl internationellt som i Sverige.

    I kapitlet redovisas en studie av personalens erfarenheter från leanarbetet i medelstora svenska tillverkningsföretag som ingått i det nationella programmet Produktionslyftet. Programmet kan ses som ett exempel på en ”svensk tolkning” av lean. Produktionslyftet har fått stort genomslag i den svenska diskussionen om lean, men samtidigt har konsekvenserna av lean ur ett arbetsmiljöperspektiv inte utvärderats på ett genomgripande sätt.

    Packages of participation: Swedish employees´experience of Lean depends on how they are involved2013In: IIE Transactions on Occupational Ergonomics and Human Factors, ISSN 2157-7323, Vol. 1, no 2, p. 93-108Article in journal (Refereed)
    Abstract [en]

    Background: Lean production is a dominant approach in Swedish and global manufacturing and service industries. Studies of Lean’s employee effects are few and contradictory. Purpose: Employee effects from Lean are likely not uniform. This article investigates the effect of employees’ participation on their experiences of Lean. Method: This study investigated how different packages of employee participation in Lean affected manufacturing workers’ experiences of Lean. During 2008–2011, qualitative and quantitative data were collected from Swedish manufacturing companies participating in the national Swedish Lean production program Produktionslyftet. Data from 129 surveys (28 companies), 39 semi-structured interviews, and 30 reports were analyzed. In the main analysis, comparisons were made of the survey-reported Lean experiences of employees in three groups: temporary group employees (N = 36), who participated in Lean mostly through intermittent projects; continuous group employees (N = 69), who participated through standing improvement groups; and combined group employees (N = 24), who participated in both ways. Results: Continuous group employees had the most positive experience of Lean, followed by the combined group. Temporary group employees had the least positive experiences, being less likely than their counterparts to report that Lean improved teamwork; occupational safety; and change-related learning, decision making, and authority. Conclusions: These findings support the importance of continuous, structured opportunities for participation but raise the possibility that more participation may result in greater workload and role overload, mitigating some benefits of employee involvement. Consequently, companies should consider involving employees in change efforts but should attend to the specific design of participation activities.

    Comparing effects in regular practice of e-communication and web-based self-management support among breast cancer patients: Preliminary results from a randomized controlled trial2014In: Journal of Medical Internet Research, ISSN 1438-8871, E-ISSN 1438-8871, Vol. 16, no 12, article id e295Article in journal (Refereed)
    Abstract [en]

    Background: While Web-based interventions have been shown to assist a wide range of patients successfully in managing their illness, few studies have examined the relative contribution of different Web-based components to improve outcomes. Further efficacy trials are needed to test the effects of Web support when offered as a part of routine care. Objective: Our aim was to compare in regular care the effects of (1) an Internet-based patient provider communication service (IPPC), (2) WebChoice, a Web-based illness management system for breast cancer patients (IPPC included), and (3) usual care on symptom distress, anxiety, depression, (primary outcomes), and self-efficacy (secondary outcome). This study reports preliminary findings from 6 months' follow-up data in a 12-month trial. Methods: We recruited 167 patients recently diagnosed with breast cancer and undergoing treatment from three Norwegian hospitals. The nurse-administered IPPC allowed patients to send secure e-messages to and receive e-messages from health care personnel at the hospital where they were treated. In addition to the IPPC, WebChoice contains components for symptom monitoring, tailored information and self-management support, a diary, and communication with other patients. A total of 20 care providers (11 nurses, 6 physicians, and 3 social workers) were trained to answer questions from patients. Outcomes were measured with questionnaires at study entry and at study months 2, 4, and 6. Linear mixed models for repeated measures were fitted to compare effects on outcomes over time. Results: Patients were randomly assigned to the WebChoice group (n=64), the IPPC group (n=45), or the usual care group (n=58). Response rates to questionnaires were 73.7% (123/167) at 2 months, 65.9 (110/167) at 4 months, and 62.3% (104/167) at 6 months. Attrition was similar in all study groups. Among those with access to WebChoice, 64% (41/64) logged on more than once and 39% (25/64) sent e-messages to care providers. In the IPPC group, 40% (18/45) sent e-messages. Linear mixed models analyses revealed that the WebChoice group reported significantly lower symptom distress (mean difference 0.16, 95% CI 0.06-0.25, P=.001), anxiety (mean difference 0.79, 95% CI 0.09-1.49, P=.03), and depression (mean difference 0.79, 95% CI 0.09-1.49, P=.03) compared with the usual care group. The IPPC group reported significant lower depression scores compared with the usual care group (mean difference 0.69, 95% CI 0.05-1.32, P=.03), but no differences were observed for symptom distress or anxiety. No significant differences in self-efficacy were found among the study groups. Conclusions: In spite of practice variations and moderate use of the interventions, our results suggest that offering Web support as part of regular care can be a powerful tool to help patients manage their illness. Our finding that a nurse-administered IPPC alone can significantly reduce depression is particularly promising. However, the multicomponent intervention WebChoice had additional positive effects.

    How user characteristics affect use patterns in web-based illness management support for patients with breast and prostate cancer.2013In: Journal of medical Internet research, ISSN 1438-8871, Vol. 15, no 3, p. e34-Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Frequently eHealth applications are not used as intended and they have high attrition rates; therefore, a better understanding of patients' need for support is warranted. Specifically, more research is needed to identify which system components target different patient groups and under what conditions.

    OBJECTIVE: To explore user characteristics associated with the use of different system components of a Web-based illness management support system for cancer patients (WebChoice).

    METHODS: For this secondary post hoc analysis of a large randomized controlled trial (RCT), in which WebChoice was tested among 325 breast cancer and prostate cancer patients who were followed with repeated measures for 1 year, usage patterns of 162 cancer patients in the intervention arm with access to WebChoice were extracted from the user log. Logistic regression was performed to identify patterns of associations between system use and patient characteristics. Latent class analyses (LCA) were performed to identify associations among the use of different system components and levels of social support, symptom distress, depression, self-efficacy, and health-related quality of life.

    RESULTS: Approximately two-thirds (103/162, 63.6%) of the patients logged on to WebChoice more than once, and were defined as users. A high level of computer experience (odds ratio [OR] 3.77, 95% CI 1.20-11.91) and not having other illnesses in addition to cancer (OR 2.10, 95% CI 1.02-4.34) increased the overall probability of using WebChoice. LCA showed that both men with prostate cancer and women with breast cancer who had low scores on social support accompanied with high levels of symptom distress and high levels of depression were more likely to use the e-message component. For men with prostate cancer, these variables were also associated with high use of the self-management advice component. We found important differences between men with prostate cancer and women with breast cancer when associations between WebChoice use and each user characteristic were analyzed separately. High use of all components was associated with low levels of social support among women with breast cancer, but not among men with prostate cancer. High use of e-messages, advice, and the discussion forum were associated with high levels of depression among women with breast cancer, but not among men with prostate cancer. For men with prostate cancer (but not women with breast cancer), high use of symptom assessments, advice, and the discussion forum were associated with high levels of symptom distress. However, it is unclear whether these findings can be attributed to differences related to diagnosis, gender, or both.

    CONCLUSIONS: This study provides evidence that different user characteristics are associated with different use patterns. Such information is crucial to target Web-based support systems to different patient groups. LCA is a useful technique to identify subgroups of users. In our study, e-messages and self-management advice were highly used components for patients who had low levels of social support and high illness burden, suggesting that patients with these characteristics may find such tools particularly useful.

    Nurses' experiences of using an interactive tailored patient assessment tool one year past implementation2013In: International Journal of Medical Informatics, ISSN 1386-5056, E-ISSN 1872-8243, Vol. 83, no 7, p. E23-E34Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Despite evidence of benefits, integration of patient-centered communication in clinical practice is challenging. Interactive tailored patient assessment (ITPA) tools can contribute to a more patient-centered care approach. However, little research has examined the impact of such tools on nursing care once they have been implemented.

    OBJECTIVE: To explore nurses' experiences of the benefits of and barriers to using an ITPA called Choice, in cancer care one year after its implementation.

    METHODS: This investigation is a part of a larger study examining the use of Choice in cancer care. Four focus group interviews were conducted with 20 nurses experienced in using the Choice application. The data were analyzed using qualitative content analysis.

    RESULTS: Three themes and nine sub-themes emerged: (1) "Choice as facilitator for shared understanding and engagement in patients' own care," with three sub-themes: preparing both patient and nurse for communication, shared engagement in care planning, and giving the patients a voice; (2) "enhancing the patients' strengths," with two sub-themes: releasing patient's internal strengths and confirming "normalcy" for the patient; and (3) "new challenges for the nurse," with four sub-themes: organizational challenges, interactions with technology, a need for training in communication skills, and new ethical challenges.

    CONCLUSIONS: Findings suggest that, from nurses' perspectives, integration of ITPAs such as Choice in clinical practice offers many benefits that can contribute to patient-centered care. However, to reap these benefits, use of such tools must receive equal priority as other routines, and require sufficient time, space and competence. Choice also challenged nurses' professional roles and created dilemmas such as nurses' ambivalence regarding patients' levels of disclosure of sensitive issues and the nurses' ability to respond to them. Although patient-centered care is advocated as model for good clinical practice, this is not always internalized. Tools such as Choice may help to make such a shift happen.

    Abstract

    Occupational injuries are a problem in healthcare in Sweden. Both occupational accidents and most of all occupational diseases caused by great physical workloads constitute a large proportion of work related musculoskeletal disorders (MSD) of healthcare professionals. The aim of the study was to explore and describe the work process in the design teams of the building design process. The main focus was the building design process of health care buildings and the design teams where ergonomists and safety engineers are asked to participate. The purpose was to create a knowledge base consisting of this study and an appendix with methods and relevant literature. Eight people with different professions were interview. All of them had a good hold on the building design processes and on hospital architecture issues. Among them there were two ergonomists and two safety engineers. The result indicates that ergonomists and safety engineers were those who possessed the knowledge of working environment factors such as ergonomics in the building design processes. The methodology was to follow the agreed plan for the building design process established by the project Manager. Moreover the role of the ergonomists and safety engineers in the design team was to coach and supervise particularly the healthcare professionals. The main approach was to create a good dialogue and conversation and to keep a solution-oriented approach in the design team. Furthermore the most important method was to visualize drawings of Architects which made it possible for the healthcare workers to be able to audit the drawings correctly. This procedure gave the healthcare professionals a decision-making support which helped them to make well-reasoned decisions about their future work environment. The conclusion indicates that ergonomists and safety engineers are important because of their unique knowledge of working environment, especially ergonomics. Ergonomists and safety engineers need to be involved in the early phases of the building design process in order to be able to influence the design of new workspaces. The participation of these two professions in the design team may also benefit the healthcare workers with a future work environment which is largely designed according to their requirements and needs and will probably help to prevent MSDs. In the future there is a need for a specific education just for the ergonomists and the safety engineers participating in the building design process of healthcare buildings. There are great opportunities for them to develop their role towards a more prominent one in the building design process.

    Abstract [en]

    Within a project called “The sustainable greenhouse as a complement to buildings” financed by the Delegation of sustainable cities in Sweden, researchers, consultants and students have during 2013 developed, tested and evaluated various solutions for cultivating under roofs in or close to dwellings. We included solutions such as cultivating a plot in a rooftop greenhouse, a circular cultivation balcony or to cultivate in one’s kitchen or living room using a fish and vegetable furniture, a green wall, a green lamp or a green frame attached to the wall. The practical trials were preceded by a literature survey that described good examples of cultivation under roofs in various cities around the world.The results show that here are many inspiring examples of cultivating under roofs in cities and that such cultivation has gained some momentum. Our practical trials show among others that urban agriculture seems challenging and appealing for many but that the solutions that we have tested seem to be too expensive and partly also too time-consuming. Those who like to cultivate do so because it is fun and they can get products of good quality. To lessen the environmental impacts are also a reason but here our results that productivity in urban farming has to be higher than in our trials in order for the products to be considered as “climate-friendly”. Growing fish at home showed to be rather unpopular and many thought that slaughtering the fish by themselves would be nasty. Others results from the project are a water cooled LED lamp built in four copies and successfully installed in a fish and vegetable production unit as well as drawings and costs estimates for a cultivation bench.Proposals for further studies include analysis of flight and nutrient requirements for cultivation under roofs in cities as well as measurements of productivity. More low cost solutions for cultivating under glass should also be developed. To expand and maintain interest and knowledge for cultivation under roofs in cities is not only important for increasing social sustainability and eventually the environmental one as well but also because of the need to enhance preparedness.

    Design for Human Behaviour and Automation: Development and Evaluation of a Holistic Warning Approach2014Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    A human-centered approach when developing new support systems in vehicles has the potential to enable the driver to make safe decisions in the transition between manual and automatic control. However, careful considerations have to be taken. Not only would the design of the systems, in terms of interface be important, but also what kind of activities the systems support. The aim of this study was to identify an appropriate activity to support the cognitive processes for truck drivers, develop an interface for this activity, and evaluate it in driving situations. This was executed in three sub-studies: the Pre-study, the Design-study, and the Evaluation study.

    In the Pre-study, the aim was to investigate for what kind of driver-related activity distribution and long haulage truck drivers need a driver support and interface. This was investigated via contribution from truck drivers, HMI/Ergonomics experts, as well as engineers. The activity chosen to support was detecting objects around the vehicle. However, reconsiderations were made due to constrains in the simulator. Suggested by Scania’s Vehicle Ergonomics group a holistic system was chosen; an interface approach enabling for more technologies to be included within the same interface, reducing the amount of modalities a driver can be exposed to.

    The Design-study addressed the aim of designing an interface for the Holistic system with truck drivers’ cognitive workload in focus. A LED-prototype was built running along the window edges inside the cab of Shania’s Vehicle Ergonomics groups’ simulator, to create warning signal concepts. Literature findings, the LED-prototype, and the simulator were used in an iterative process to design and improve warning signal concepts, until two final concepts were created. The holistic system informs of hazards around and near the vehicle by lighting the area risky objects occurs to guide drivers’ attention and this was done either with 1) the informative display or, 2) the directional display. The Informative display conveys information of a hazard location and type, and the Directional display exclusively conveys information of the hazard location.

    The Evaluation study explored how drivers were affected by, and how they perceived, the holistic interface design regarding mental workload and hazard detection. A user simulator test was designed to collect data within the areas of ‘Event detection’, ‘Workload’, ‘Driving performance’ and ‘Subjective opinion’. Fourteen professional truck drivers assessed three conditions: 1) Baseline (driving without a system), 2) the Informative display, and, 3) the Directional display, while being exposed to potential hazards. To further increase workload, a secondary task was performed at the end of each condition.

    The results showed that the Informative display did not only result in more ‘Detection hits’, instances when a driver responded to a present hazard, but also significantly decreased reaction time to detect a hazard. However, in terms of acceptance, the two concepts were considered equally preferred. As the Informative display showed to be more efficient in terms of hazard detection, this should be investigated further. A holistic interface enables for more systems to be included within the same interface, reducing the amount of alarms and modalities drivers are exposed to if designed skillfully. Thus, more support systems can be included in future vehicles, without causing unnecessary distraction when applying a holistic interface approach.

    Behavioral factors influencing partner trust in logistics collaboration: a review2016In: Logistics Research, ISSN 1865-035X, Vol. 9, no 1, article id 19Article in journal (Refereed)
    Abstract [en]

    Logistics collaboration has emerged a prevalent strategy to mitigate challenge individuals and organizations encounter. A successful collaboration, however, depends on certain trustworthy behaviors partner exhibit. To that end, understanding aspects constituting behavioral uncertainty and mechanisms by which such aspects affect partner trust is a necessary. This necessity counts on emergent behavioral trust uncertainties, constituted by partner’s actions and interactions occurring during collaboration. While this is a necessary requirement, most of the studies in the literature lack to take into account the influence of behavioral uncertainty on collaboration and partner trust. To that effect, this paper uncovers outlined limitation by establishing behavioral factors influencing partner trust in operational stage of logistics collaboration. To accomplish this objective, a systematic literature review (SLR) is deployed to consolidate research domains of logistics, supply chain, collaboration, and trust. SLR proceeds by defining a review protocol, followed by a search process conducted in 5 databases using 20 search terms on articles published between 2001 and 2015 inclusively. Among findings this SLR has revealed are four behavioral factors and thirteen criteria proposed to affect partner trust. Additionally, these factors constitute success and measurable criteria needed for empirical investigation which may employ experimental and/or case-study methods. Moreover, synthesized factors extend further an understanding of behavioral trust in ad hoc collaborative networks, a large part of which being supported by networks of humans and computers.

    A Trust Framework for Agents' Interactions in Collaborative Logistics2017In: DYNAMICS IN LOGISTICS, LDIC 2016, Springer, 2017, p. 53-63Conference paper (Refereed)
    Abstract [en]

    Trust is an essential factor for successful resource sharing in logistics. To build and sustain trust among collaborating partners in logistics requires, amongst others, conceptualizing on various aspects constituting underlying mistrusts. The conception is achieved by setting up a framework describing trust-based collaborative interactions of these partnering entities, referred to as agents. This research establishes a trust framework addressing agents' trustworthy interactions and thus aims at overcoming a knowledge gap identified in the literature. The framework depicts trust-based interactions concentrating to sharing of vehicle capacities. The trust framework is conceived on a foundation of theoretical body of knowledge in the literature. It engages knowledge on collaborative networks, logistics and transportation, agent behavior as well as trust. This research contributes by identifying key agents together with their roles, characteristics, tasks, information exchange as well as perceptions; all of which linked to agent trust. The framework is reusable in many ways, including formal conception of models aspiring to empirically investigate trust amongst agents sharing logistics resources. It also provides more understanding to practitioners, especially on issues relating to compromising differences resulting from agent's perspectives.

    Hur kan stödresurser understödja hållbart ledarskap bland chefer i vården?2013In: Socialmedicinsk Tidskrift, ISSN 0037-833X, Vol. 90, no 6Article in journal (Refereed)
    Abstract [sv]

    Chefer kan ha stor betydelse för anställdas hälsa, stress, engagemang i arbetet och prestation. Få tidigare studier har undersökt vilket stöd chefer behöver för ett hållbart och bra ledarskap. Artikeln presenterar resultat från en prospektiv studie om betydelsen av chefers stödresurser för hållbart ledarskap. I studien, som är en del av Chefios-projektet, ingår chefer i kommunal vård och omsorg (n=344). Data från enkätstudier med instrumentet ”Gothenburg Manager Stress Inventory” har analyserats. Resultatet visar att ett stödjande privatliv och en personlig inställning till chefsuppdrag har stor betydelse för chefers hållbarhet över tid. Chefens kontrollspann och erfarenhet som chef påverkade betydelsen av stödresurser. För chefer med kortare chefserfarenhet eller fler underställda (>30) har även stöd från ledning, chefskollegor och externt stöd betydelse.

    Health-Promoting Managerial Work: A Theoretical Framework for a Leadership Program that Supports Knowledge and Capability to Craft Sustainable Work Practices in Daily Practice and During Organizational Change2017In: Societies, ISSN 1090-9389, E-ISSN 2075-4698, Vol. 7, no 2, article id 12Article in journal (Refereed)
    Abstract [en]

    The aim of this article is to describe a theoretical framework, i.e., theoretical underpinnings and pedagogical principles, for leadership programs that support managers' evidence-based knowledge of health-promoting psychosocial work conditions, as well as their capability to apply, adapt, and craft sustainable managerial work practices. First, the theoretical framing is introduced, i.e., a system theory that integrates key work conditions with a practical perspective on managerial work and organization. Second, pedagogical principles and measures for leaders' training in integrated handling across system levels are described. Last, we present summarized results from an intervention study applying the theoretical framework and pedagogical principles. The complexity of interactions among different factors in a work system, and the variety in possible implementation approaches, presents challenges for the capability of managers to craft sustainable and health-promoting conditions, as well as the evaluation of the program components. Nevertheless, the evaluation reveals the strength of the program, in providing holistic and context-sensitive approaches for how to train and apply an integrative approach for improving the work environment.
