Background
Obesity presents a unique challenge in caring for surgical patients and has been shown to adversely affect outcomes for several operative procedures. However, quantitative data on surgical resource utilization attributable to obesity are scarce. The aim of this study was to quantify day-of-surgery resource utilization by degree of obesity.
Methods
Patients undergoing one of 14 common surgical procedures at our multicenter institution between 2008 and 2017 were identified from our operating room management databank. Multiple-variable regression analysis (MVRA) was performed to quantify the independent effect of body mass index (BMI) category on day-of-surgery resource utilization variables including procedure time, non-operative OR time, PACU time, number of unique staff and number of supplies used. Trends in mean BMI were examined for each procedure studied.
Results
MVRA of the 189,264 cases in the database revealed consistently significant (p < 0.05) stepwise increase in procedure time by BMI category for all procedures studied. Non-operative OR time was also significantly prolonged, though to a lesser degree. There was no significant impact on number of unique staff, supplies utilized or PACU time by BMI category. Procedures most impacted by BMI category in terms of resource utilization were ventral hernia repair, laminectomy and hysterectomy.
Conclusion
Our study quantified day-of-surgery resource utilization for 14 major surgical procedures by BMI category. The need for additional resources to accommodate patients in higher BMI groups was consistent across all procedures studied and was primarily reflected by lengthened operative times.
