    Medical Technology and eHealth for Prevention against LifestyleRelated Diseases: A survey of attitudes among health center personnel and patients prescribed with physical activity on prescription (PAP)2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    With an aging population that suffers from comorbidity, healthcare is facing grand challenges. In order to meet the demand, digitalization is thought to be an opportunity. Digitalization of curative care, such as diagnostics and treatment, have been initiated and is today used and appreciated. Preventative care, on the other hand, has not been included in the digital adaptions to the same extent and there are few scientific studies within the area. Nonetheless, a further proactive care that meets patients and healthcare personnel are of interest to several actors. The Swedish Government has a vision that Sweden, in 2025, will be world leading within eHealth. For that to be possible, digital preventative care have to support and complete the preventative work that is performed today.

    The present study has investigated the attitude towards Connected Medical Devices for Prevention (CMDfP) within the primary care. By a mixed-methodology including questionnaires, the opinions of 24 health center personnel and 17 patients prescribed with Physical Activity on Prescription (PAP) were collected and analyzed. The results show that health center personnel are willing to prescribe connected eHealth devices for prevention and patients are willing to use the devices prescribed. Additionally, among the respondents there is a belief that CMDfP could facilitate in order to increase the adherence to PAP without any major impact on the personnel's workload.

    By digitalizing preventative care, it is possible that people will be able to live healthier and therefore not require care to the same extent as today. Reasons to the possible results are that digital tools within curative care have been shown to generate positive outcomes to chronically ill patients that utilize home care. Additionally, studies of preventative care have generated positive outcomes to the health of the population in several countries. It is therefore likely that the combination, digital preventative care, would be rapidly relished. These thoughts align with the positive results on attitudes of this study.

    Before CMDfP could be prescribed to patients, pilot studies have to be performed and new work routines including reimbursement models, have to be established within healthcare. These are all areas of future work within medical engineering.

    Aiding Remote Diagnosis with Text Mining2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The topic of this thesis is on how text mining could be used on patient-reported symptom descriptions, and how it could be used to aid doctors in their diagnostic process. Healthcare delivery today is struggling to provide care to remote settings, and costs are increasing together with the aging population. The aid provided to doctors from text mining on patient descriptions is unknown.Investigating if text mining can aid doctors by presenting additional information, based on what patients who write similar things to what their current patient is writing about, could be relevant to many settings in healthcare. It has the potential to improve the quality of care to remote settings and increase the number of patients treated on the limited resources available. In this work, patient texts were represented using the Bag-of-Words model and clustered using the k-means algorithm. The final clustering model used 41 clusters, and the ten most important words for the cluster centroids were used as representative words for the cluster. An experiment was then performed to gauge how the doctors were aided in their diagnostic process when patient texts were paired with these additional words. The results were that the words aided doctors in cases where the patient case was difficult and that the clustering algorithm can be used to provide the current patient with specific follow-up questions.

    Improvements within patient experience during MRI2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    MRI is one of the biggest and most growing imaging techniques. Even though itis one of the most harmless technologies a big portion of the patients experienceanxiety during the exam. By improving the patient experience unnecessary psychologicalstress for the patient can be prevented, the patient movement wouldthen decrease and therefore the imaging can be improved without changing thetechnique. Participant observations at four dierent MRI departments werecompleted with six interviews with radiographers and technical MRI personnelin order to get insight in the work around an MRI exam and the problemsthat patients experience. The data collection resulted in three improvementareas: the atmosphere of the waiting room, the atmosphere of the MRI roomand the headset used by the patient during the MRI exam. These improvementareas were paired up with solution suggestions which were then controlled andcommented by one MRI specialist, one MRI developer and one radiographer tovalidate the suggestions. The conclusion was that there is already much doneto improve the environment in the MRI room, even though more can be done.The waiting room, on the other hand ,has not been an object for studies orfor improvements before. Therefore more calculation about how big of a protit could be, to improving the atmosphere in the waiting room, should be doneso one knows how much resources one can be put into that improvement area.Lastly there are potential solutions for how to create a much better headset butbecause the generated solutions in this area are so technically challenging moreresearch has to be done before it can be realised.

    Public, personal and municipal perception of eHealth in home care2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This project was initiated due to the need for new manners of taking care of elderly. The purpose was to determine the perception of eHealth within home care. The goal was to analyze the perception of eHealth in order to find factors which may affect the implementation of eHealth services.

    To distinguish the perception, surveys with health personnel within home care and the general public as well as and interviews with municipalities were performed. An extension of the Technology Acceptance Model was used in order to locate the perception to seven different categories related to eHealth. The results from the surveys were statistically analysed, and a factor analysis was executed on the surveys, in order to find groups with similar perception on eHealth.

    The surveys showed that the general perception of the usability and ease of use of eHealth is positive, even though one view was that the society needs to invest more money within the area. The factor analysis resulted in six different groups of perceptions for the personnel and three groups for the general public. The interviews demonstrated that a clear and common definition of eHealth is missing. Despite that, a positive perception of eHealth within the municipalities existed. A conclusion made was that with clear guidelines of how to work eHealth, a wider and faster implementation will be easier to accomplish.
