Patient and Provider-Identified Factors Contributing to Surgical Readmission After Colorectal Surgery

Purpose: Nearly one in seven surgical patients is readmitted to the hospital within 30days of discharge. Few studies have identified patient-centric factors that raise the risk of both preventable and nonpreventable postoperative readmissions. Materials and Methods: Over 6 months in 2012, 48 colorectal surgical patients were identified on re-admission within 30days of discharge. We prospectively obtained information on the patient's and primary surgeon's views on factors that contributed to readmission, and compiled data to produce an external list of contributing factors. A standard cost analysis was performed. Results: 48 colorectal surgery patients participated, and 47 were included in this patient-centric evaluation of factors leading to readmission. The three primary readmission diagnoses included dehydration, fever, and ileus or small bowel obstruction. Of all readmissions, 23% were considered to be preventable. 38% of patients had scheduled follow-up appointments that were documented in the medical record at the time of discharge. Providers identified several factors contributing to readmission including difficulty understanding discharge plan, medication management and premature discharge. Per patient, the cost of preventable readmission was $15,366 (+/- 20%; $12,293-$18,439). Total preventable cost was $169,025 (+/- 20%; $135,220-$202,829). Conclusions: The ability to obtain an outpatient postoperative appointment and the understanding of their own postoperative care were the most commonly identified barriers. Interventions to help reduce unnecessary readmissions include a standard discharge process and coordinator, and routine (<7days) postdischarge outpatient appointments. Successful reduction of preventable readmissions would result in approximately $3.6 million in cost savings per 1,000 colorectal readmissions.
