Patient Compliance With Bowel Preparation for Elective Colorectal Surgery

Introduction: Studies show that mechanical bowel preparation (MBP) plus oral antibiotics (OAs) is associated with decreased rates of postoperative complications after elective colorectal surgery. However, there is a lack of literature regarding patient compliance with bowel preparation (BP). Materials and methods: Patients undergoing elective colorectal surgeryfrom April 2020 to March 2022 at a tertiary care academic hospital (TCAH) and safety net hospital (SNH) were administered a BP compliance survey. Patients were compared on the basis of hospital setting and completeness of BP using student's t-tests and Fisher's exact tests, as appropriate. Results: 105 patients were included as follows: 55 from the TCAH and 50 from the SNH. The median age was 59. 45.7% were female. TCAH had a higher proportion of White patients (36.4% versus 0%), while the SNH had a higher proportion of Hispanic patients (78% versus 10.9%). Most patients at the TCAH reported English as their primary language (80% versus 28%), while most patients at the SNH spoke primarily Spanish (60% versus 7.3%). In total, 88.6% (n = 93) of patients completed the MBP- 87.3% at the TCAH and 90% at the SNH (P = 0.764). 86.7% took all three doses of OA. Compared to the SNH patients, a smaller percentage of TCAH patients took all doses of OA (78.2% versus 96%, P = 0.009). Overall, 45.7% of patients reported adverse symptoms with BP. The only patient factor associated with a complete bowel preparation was SNH setting (P = 0.024). Conclusions: Overall, almost 90% of patients were compliant with both MBP and OA. Compliance with OA among patients at the TCAH was significantly lower compared to patients at the SNH. An SNH setting was associated with completing a BP. Individual compliance is likely impacted by both institutional practices and patient factors. (c) 2024 Published by Elsevier Inc.
