Automatiserade hermetiskt slutna jämfört med konventionella avfallshanteringssystem på sjukhus : En jämförande studie av mikrobiell närvaro (Swedish)
Abstract [en]

This study assesses the effectiveness of automated hermetically sealed waste management systems compared to conventional waste disposal methods in reducing microbial loads in hospitals. A comparative analysis was conducted between Södersjukhuset, which utilizes the automated system, and Östra Sjukhuset, which employs a conventional system. Microbial presence was quantified through colony forming units (CFUs). Results demonstrate that Södersjukhuset experienced a 49.3% reduction in mean CFU count and a 6.10% reduction in median CFU count compared to Östra Sjukhuset. Statistical analysis using the Mann-Whitney U test produced a p-value of 0.055, slightly above the significance threshold of 0.05, providing limited statistical support of the difference in microbial load between the hospitals. Hence, the findings suggest that there may be a potential for automated waste management systems to improve hospital sanitation and patient safety.

Abstract [sv]

Denna studie undersöker effektiviteten av automatiserade hermetiskt slutna avfallshanteringssystem jämfört med konventionella avfallshanteringsmetoder på sjukhus, med fokus på deras påverkan på mikrobiell närvaro. Genom en jämförande analys mellan Södersjukhuset, utrustat specifikt med Envacs automatiserade system, och Östra Sjukhuset som använder den konventionella metoden, kvantifierar studien bakteriekontamineringsnivåer genom kolonibildande enheter (CFU). Resultaten visade ett 49,3% lägre genomsnittligt CFU-antal och ett 6,10% lägre median CFU-antal på Södersjukhuset jämfört med Östra Sjukhuset, vilket tyder på att automatiserade system avsevärt minskar mikrobiell kontaminering. Mann-Whitney U-testet gav ett p-värde på 0,055 och därför implicerar begränsat statistiskt stöd för skillnaden i mikrobiell belastning mellan sjukhusen. Därav tyder resultaten på att det kan finnas en potential för automatiserade avfallshanteringssystem att förbättra sjukhussanering och patientsäkerhet.
