Acute health care resource utilization for ileostomy patients is higher than expected.
BACKGROUND
Patients requiring an ileostomy following colorectal surgery are at risk for increased health-care utilization after discharge. Prior studies evaluating postoperative ileostomy care may underestimate health-care utilization by reporting only "same-institution" readmission rates.


OBJECTIVE
The aim of this study was to determine the rates of health-care utilization of new ostomates within 30 days of discharge in a multicenter environment.


METHODS
This is a retrospective cohort study.


METHODS
This study was conducted at acute-care, community hospitals in California, Florida, Nebraska, and New York.


METHODS
Adult patients who underwent colorectal surgery with primary anastomosis, colostomy, or ileostomy between July 2009 and September 2010 were identified.


METHODS
The primary outcome measured was hospital-based acute care, defined as hospital readmission or emergency department visit, at any hospital within 30 days of surgery. Multivariate regression models were used to compare the outcomes across groups.


RESULTS
Overall, 75,136 patients underwent colectomy with most receiving a primary anastomosis (79.3%), whereas colostomies were created in 12.8% and ileostomies were created in 8.0%. Diagnoses of colorectal cancer (36.1%) or diverticular disease (22.0%) were most common. Patients with a colostomy (18.8%; adjusted odds ratio [AOR], 1.23 [95% CI, 1.17-1.30]) or ileostomy (36.1%; AOR, 2.28 [95% CI 2.15-2.42]) were significantly more likely than patients with a primary anastomosis (16.2%) to have a hospital-based acute-care encounter within 30 days of discharge. Among patients undergoing ileostomy, postoperative infection, renal failure, and dehydration were the most common diagnoses for hospital-based acute-care events. Overall, 20% of these encounters occurred at hospitals other than where the index surgery occurred.


CONCLUSIONS
Coding accuracy, the inability to capture events occurring in physician offices, and the retrospective study design were limitations of the study.


CONCLUSIONS
Patients undergoing colorectal surgery with an ileostomy return to the hospital after discharge twice as frequently as those with a primary anastomosis or colostomy, often to hospitals other than the primary institution. As postdischarge health-care utilization becomes a measured quality metric, it is increasingly important to help these patients to safely transition to home.
