Human Factors Contributing to Infection Prevention in Outpatient Hemodialysis Centers: A Mixed Methods Study
American Journal of Kidney Diseases(2024)
摘要
Rationale & Objective
Infection prevention efforts in dialysis centers can avert patient morbidity and mortality but are challenging to implement. The objective of this study was to better understand how the design of the work system might contribute to infection prevention in outpatient dialysis centers.
Study Design
Mixed methods, observational study.
Setting & Participants
Six dialysis facilities across the United States were visited by a multidisciplinary team over 8 months.
Analytical Approach
At each facility, structured macroergonomic observations were undertaken by a multidisciplinary team using the SEIPS 1.0 model. Ethnographic observations were collected about staff encounters with dialysis patients including the content of staff conversations. Selective and axial coding were used for qualitative analysis and quantitative data were reported using descriptive statistics.
Results
Organizational and sociotechnical barriers and facilitators to infection prevention in the outpatient dialysis setting were identified. Features related to human performance, (e.g., alarms, interruptions, and task stacking), work system design (e.g., physical space, scheduling, leadership, and culture), and extrinsic factors (e.g., patient-related characteristics) were identified.
Limitations
This was an exploratory evaluation. A small sample size.
Conclusion
This study used a systematic macroergonomic approach in multiple outpatient dialysis facilities to identify infection prevention barriers and facilitators related to human performance. Several features common across facilities were identified that may influence infection prevention in outpatient care and warrant further exploration.
