Abstract
BACKGROUND: To evaluate readmissions to determine predictors and patterns of readmission. METHODS: Prospective database review identified readmitted and non-readmitted patients after colorectal surgery. Variables for the index and readmission episode were examined. RESULTS: A total of 212 readmissions and 3,292 nonreadmissions were analyzed. The majority was elective. Readmitted patients were older (P = .003), had more comorbidities (P < .0001), longer operative times (P < .0001), length of stay (P < .0001), and higher costs (P = .002). At the time of discharge, more readmitted patients required temporary nursing (P < .0001). Independent readmission predictors were higher American Society of Anesthesiologists score, previous abdominal operation, intensive care unit stay, and dysmotility/constipation surgery. At the time of readmission, 29.2% required reoperation. More than half had an open procedure initially (55.2%). After initial open procedures, reoperative time (P = .05) and LOS were longer (P = .028), and more patients required temporary nursing care at the time of discharge (P = .046). Readmissions caused an additional mean hospital cost of $12,670.89. CONCLUSIONS: Readmitted patients have distinct demographic and outcomes variables. As most were elective cases, stratifying patients preoperatively may enable perioperative planning for this higher risk group.
