The impact of accreditation on safety and cost of bariatric surgery.

ABSTRACT: The objective of this study was to examine how much of the impact of the Centers for Medicare and Medicaid Services' national coverage decision (NCD) on bariatric surgery was driven by the restriction of reimbursements to Centers of Excellence (COE). We used inpatient care data of those with employer-sponsored insurance plans across United States using the MarketScan Commercial Claims and Encounter Database (2003-2009).We performed a retrospective cohort study evaluating the impact of the accreditation on subjects with a difference-in-difference approach (removing the temporal changes occurring in non-COEs) on rates of inpatient mortality, 90-day reoperations, complications, readmissions, and total payments.A total of 30,755 patients (43.9 ± 11.0 years; 79.9% women) had bariatric surgery. A total of 17,896 patients underwent procedures at sites that became COEs (8455 pre-NCD and 9441 post-NCD, [+10.4%]) compared with 12,859 at non-COEs (6534 pre-NCD and 6325 post-NCD, [-3.3%]). Of the total number of bariatric procedures, laparoscopic Roux-en-Y gastric bypass and laparoscopic adjustable band procedures increased from 42.9% and 3.1% pre-NCD to 64.5% and 19.7% post-NCD, respectively. In the COEs, there were reductions in inpatient mortality (.3% to .1%; P = .02), 90-day reoperations (.8% to .5%; P = .006), complications (36.4% to 27.6%; P<.001), and readmissions (10.8% to 8.8%; P<.001) while payments remained similar ($24,543 ± $40,145 to $24,510 ± $37,769; P = .9). After distinguishing from temporal trends and differences occurring at non-COEs, 90-day reoperation (-.8%; P = .02) and complication rates (-2.7%; P = .01) were lower at the COEs after the NCD.The accreditation-based NCD in bariatric surgery was associated with lower rates of reoperations and complications. Such policies may become a powerful tool to improve surgical safety and quality.

Project description:BackgroundTo improve decision making in the treatment of extreme obesity, the risks of bariatric surgical procedures require further characterization.MethodsWe performed a prospective, multicenter, observational study of 30-day outcomes in consecutive patients undergoing bariatric surgical procedures at 10 clinical sites in the United States from 2005 through 2007. A composite end point of 30-day major adverse outcomes (including death; venous thromboembolism; percutaneous, endoscopic, or operative reintervention; and failure to be discharged from the hospital) was evaluated among patients undergoing first-time bariatric surgery.ResultsThere were 4776 patients who had a first-time bariatric procedure (mean age, 44.5 years; 21.1% men; 10.9% nonwhite; median body-mass index [the weight in kilograms divided by the square of the height in meters], 46.5). More than half had at least two coexisting conditions. A Roux-en-Y gastric bypass was performed in 3412 patients (with 87.2% of the procedures performed laparoscopically), and laparoscopic adjustable gastric banding was performed in 1198 patients; 166 patients underwent other procedures and were not included in the analysis. The 30-day rate of death among patients who underwent a Roux-en-Y gastric bypass or laparoscopic adjustable gastric banding was 0.3%; a total of 4.3% of patients had at least one major adverse outcome. A history of deep-vein thrombosis or pulmonary embolus, a diagnosis of obstructive sleep apnea, and impaired functional status were each independently associated with an increased risk of the composite end point. Extreme values of body-mass index were significantly associated with an increased risk of the composite end point, whereas age, sex, race, ethnic group, and other coexisting conditions were not.ConclusionsThe overall risk of death and other adverse outcomes after bariatric surgery was low and varied considerably according to patient characteristics. In helping patients make appropriate choices, short-term safety should be considered in conjunction with both the long-term effects of bariatric surgery and the risks associated with being extremely obese.

Project description:ImportanceObesity is the most common risk factor for nonalcoholic steatohepatitis (NASH), the progressive form of nonalcoholic fatty liver disease that can lead to cirrhosis and hepatocellular carcinoma. Weight loss can be an effective treatment for obesity and may slow the progression of advanced liver disease.ObjectiveTo assess the cost-effectiveness of bariatric surgery in patients with NASH and compensated cirrhosis.Design, setting, and participantsThis economic evaluation study used a Markov-based state-transition model to simulate the benefits and risks of laparoscopic sleeve gastrectomy (SG), laparoscopic Roux-en-Y gastric bypass (GB), and intensive lifestyle intervention (ILI) compared with usual care in patients with NASH and compensated cirrhosis and varying baseline weight (overweight, mild obesity, moderate obesity, and severe obesity). Patients faced varied risks of perioperative mortality and complications depending on the type of surgery they underwent. Data were collected on March 22, 2017.Main outcomes and measuresLife-years, quality-adjusted life-years (QALYs), costs (in 2017 $US), and incremental cost-effectiveness ratios (ICERs) were calculated.ResultsDemographic characteristics of the patient population were based on a previously published prospective study (n = 161). Patients in the model were 41.0% female, and the base case age was 54 years. Compared with usual care, SG was associated with an increase in QALYs of 0.263 to 1.180 (bounds of ranges represent overweight to severe obesity); GB, 0.263 to 1.207; and ILI, 0.004 to 0.216. Sleeve gastrectomy was also associated with an increase in life-years of 0.693 to 1.930; GB, 0.694 to 1.947; and ILI, 0.012 to 0.114. With usual care, expected life-years in overweight, mild obesity, moderate obesity, and severe obesity were 12.939, 11.949, 10.976, and 10.095, respectively. With usual care, QALY in overweight was 6.418; mild obesity, 5.790; moderate obesity, 5.186; and severe obesity, 4.577. Sleeve gastrectomy was the most cost-effective option for patients across all weight classes assessed: ICER for SG in patients with overweight was $66 119 per QALY; mild obesity, $18 716 per QALY; moderate obesity, $10 274 per QALY; and severe obesity, $6563 per QALY. A threshold analysis on the procedure cost of GB found that for GB to be cost-effective, the cost of the surgery must be decreased from its baseline value of $28 734 by $4889 for mild obesity, by $3189 for moderate obesity, and by $2289 for severe obesity. In overweight patients, GB involved fewer QALYs than SG, and thus decreasing the cost of surgery would not result in cost-effectiveness.Conclusions and relevanceBariatric surgery could be highly cost-effective in patients with NASH compensated cirrhosis and obesity or overweight. The findings from this analysis suggest that it can inform clinical trials evaluating the effect of bariatric procedures in patients with NASH cirrhosis, including those with a lower body mass index.
