Reducing New Ileostomy Readmissions in a Rural Health Care Setting: A Quality Improvement Initiative

BACKGROUND: Readmission after ileostomy creation continues to be a major cause of morbidity with rates ranging from 15% to 30% due to dehydration and obstruction. Rural environments pose an added risk of readmission due to larger travel distances and lack of consistent home health services. OBJECTIVE: This study aimed to reduce ileostomy-related readmission rates in a rural academic medical center. DESIGN: This is a rapid cycle quality improvement study. SETTING: This single-center study was conducted in a rural academic medical center. PATIENTS: Colorectal surgery patients receiving a new ileostomy were included in this study. INTERVENTIONS: Improvement initiatives were identified through Plan-Do-Study-Act cycles (enhanced team continuity, standardized rehydration, nursing/staff education). MAIN OUTCOME MEASURES: Thirty-day readmission, average length of stay, and average time to readmission served as main outcome measures. RESULTS: Roughly equal rates of ileostomy were created in each time point, consistent with a tertiary care colorectal practice. The preimplementation readmission rate was 29%. Over the course of the entire quality improvement initiative, re-admission rates decreased by more than 50% (29% to 14%). PDSA cycle 1, which involved integrating a service-specific physician assistant to the team, allowed for greater continuity of care and had the most dramatic effect, decreasing rates by 27.5% (29% to 21%). Standardization of oral rehydration therapy and the implementation of a patient-directed intake/output sheet during PDSA cycle 2 resulted in further improvement in readmission rates (21% to 15%). Finally, implementation of nurse and physician assistant (PA)-driven patient education on fiber supplementation resulted in an additional yet nominal decrease in readmissions (15% to 14%). Latency to readmission also significantly increased throughout the study period. LIMITATIONS: This study was limited by its small sample size in a single-center study. CONCLUSION: Implementation of initiatives targeting enhanced team continuity, the standardization of rehydration therapies, and improved patient education decreased readmission rates in patients with new ileostomies. Rural centers, where outpatient resources are not as readily available or accessible, stand to benefit the most from these types of targeted interventions to decrease readmission rates.
