To understand factors leading to all-cause 30-day readmissions in a community hospital population.
Structured case series of 537 readmissions using chart reviews, interviews with treating physicians, patients and family caregivers, and overall case assessment by a nurse-physician team.
Eighteen Kaiser Permanente Northern California hospitals.
Forty-seven percent (250) of readmissions were assessed as potentially preventable; 11% (55) were assessed as very or completely preventable; and 36% (195) as slightly or moderately preventable. On average, 8.7 factors contributed to each potentially preventable readmission. Factors were related to care during the index stay (in 143 cases, 57% of potentially preventable readmissions), the discharge process (168, 67%), and follow-up care (197, 79%). Missed opportunities to prevent readmissions were also related to quality improvement focus areas: transitions care planning and care coordination, clinical care, logistics of follow-up care, advance care planning and end-of-life care, and medication management.
Multiple factors contributed to potentially preventable readmissions in an integrated health care system with low baseline readmission rates. Reducing all-cause 30-day readmissions may require a comprehensive approach addressing these areas. Future quality improvement efforts and research should identify existing and new tactics that can best prevent readmissions by addressing missed opportunities we identified.
