Exploring the preventable causes of unplanned readmissions using root cause analysis: Coordination of care is the weakest link

Importance: Unplanned readmissions within 30 days are a common phenomenon in everyday practice and lead to increasing costs. Although many studies aiming to analyze the probable causes leading to unplanned readmissions have been performed, an in depth-study analyzing the human (healthcare worker)-, organizational-, technical-, disease-and patient-related causes leading to readmission is still missing. Objective: The primary objective of this study was to identify human-, organizational-, technical-, disease-and patient-related causes which contribute to acute readmission within 30 days after discharge using a Root-Cause Analysis Tool called PRISMA-medical. The secondary objective was to evaluate how many of these readmissions were deemed potentially preventable, and to assess which factors contributed to these preventable readmissions in comparison to non-preventable readmissions. Design: Cross-sectional retrospective record study. Setting: An academic medical center in Amsterdam, The Netherlands. Participants: Fifty patients aged 18 years and older discharged from an internal medicine department and acutely readmitted within 30 days after discharge. Main outcome measures: Root causes of preventable and unpreventable readmissions. Results: Most root causes for readmission were disease-related (46%), followed by human (healthcare worker)-(33%) and patient-(15%) related root causes. Half of the readmissions studied were considered to be potentially preventable. Preventable readmissions predominantly had human-related (coordination) failures. Conclusion and relevance: Our study suggests that improving human-related (coordinating) factors contributing to a readmission can potentially decrease the number of preventable readmissions.
