Evaluation of Cost Reduction Measures at a State University Medical Center.

Components of a Perioperative Surgical Home (PSH), implemented at a large State University Medical Center (SUMC), have driven significant reductions in Surgical Site Infections (SSIs) and Day of Surgery (DOS) cancellations. Refined methodology for efficient and accurate assessment of these reductions was developed based on available electronic data systems and proven strategies adapted from literature. At our institution, the practice of evidence-based protocol-driven medicine has contributed to the prevention of an estimated 1073 SSIs over a 6 year period, representing avoided costs in excess of $24M. Management of logistics surrounding patients' surgeries starting in the preoperative clinic has yielded exceedingly low DOS cancellation rates (3.47% of scheduled procedures). This level of efficiency is critical given that a 1% increase in DOS cancellation rates can represent as much as a $5.6M loss of revenue to a large SUMC.

Obesity status and use of general surgery resources.

Obesity is a rapidly growing epidemic. This study assesses the impact of obesity on surgeon workload for general surgical services. A retrospective study of patients undergoing cholecystectomy, unilateral mastectomy, and colectomy between January 2000 and December 2003 was undertaken. Obesity was defined as body mass index > or = 30. The proportion of obese patients was compared to the 2002 BRFSS obesity prevalence data for Alabama. Data were adjusted to control for potential confounders. Odds ratios (OR) and 95% confidence intervals (CI) were calculated. A total of 1,385 patients were included in analysis. The prevalence of obesity in the study population was 35.5 per cent compared to the statewide prevalence of 25.2 per cent (OR = 1.73, 95% CI = 1.51, 1.98). These data were stratified by procedure, age, and gender. The cholecystectomy group had a significantly higher proportion of obese for all age groups and female gender. The mastectomy group had a higher proportion of obese in the 45-64 age group. The stratified colectomy group did not reach statistical significance. There was no evidence of referral bias to explain these findings. This study demonstrates there is a greater use of general surgery services, particularly cholecystectomy and mastectomy, in obese patients than predicted by the prevalence of obesity in the population.

Impact of obesity on resource utilization for general surgical procedures.

OBJECTIVE: To determine the impact of the obesity epidemic on workload for general surgeons. SUMMARY BACKGROUND DATA: In 2001, the prevalence of obesity in the United States reached 26%, more than double the rate in 1990. This study focuses on the impact of obesity on surgical practice and resource utilization. METHODS: A retrospective analysis was done on patients undergoing cholecystectomy, unilateral mastectomy, and colectomy from January 2000 to December 2003 at a tertiary care center. The main outcome variables were operative time (OT), length of stay (LOS), and complications. The key independent variable was body mass index. We analyzed the association of obesity status with OT, LOS, and complications for each surgery, using multivariate regression models controlling for surgeon time-invariant characteristics. RESULTS: There were 623 cholecystectomies, 322 unilateral mastectomies, and 430 colectomies suitable for analysis from 2000 to 2003. Multivariable regression analyses indicated that obese patients had statistically significantly longer OT (P < 0.01) but not longer LOS (P > 0.05) or more complications (P > 0.05). Compared with a normal-weight patient, an obese patient had an additional 5.19 (95% confidence interval [CI], 0.15-10.24), 23.67 (95% CI, 14.38-32.96), and 21.42 (95% CI, 9.54-33.30) minutes of OT with respect to cholecystectomy, unilateral mastectomy, and colectomy. These estimates were robust in sensitivity analyses. CONCLUSIONS: Obesity significantly increased OT for each procedure studied. These data have implications for health policy and surgical resource utilization. We suggest that a CPT modifier to appropriately reimburse surgeons caring for obese patients be considered.
