Factors Associated with Inpatient Narcotic Medication Usage after Robotic-assisted Laparoscopy

Abstract

Study Objective: Describe factors that contribute to an increased narcotic medication use after robotic-assisted laparoscopic (RAL) surgery. Design: A retrospective cohort. Setting: A teaching hospital. Patients: All patients undergoing RAL surgery by gynecologist oncologists at St. Joseph's Hospital and Medical Center over a 3-year period. Interventions: RAL by gynecologist oncologists. Measurements and Main Results: Using retrospective chart review, patients who underwent RAL surgery from 2012 to 2015 in the division of gynecologic oncology were identified; 757 patients were eligible for inclusion in the study. Total narcotic use during the postoperative hospital stay was converted to oral morphine milligram equivalents (OME). Bivariate correlations of total OME narcotics to multiple variables were evaluated using Spearman's rho. The average age, body mass index, and length of stay were 53.76 years (17–92), 31.75 kg/m2 (17–56), and 1.56 days (range, 0–19), respectively. Increased OME correlated positively with body mass index (Spearman's rho =.077, p =.036), any intraoperative complication (Spearman's rho =.05, p =.886), any postoperative complication (Spearman's rho =.16, p
