The aim of this study was to determine the feasibility of "hot spotting" in elective surgical populations.Prospective identification of high-cost patients, known as "hot spotting," is well developed in medical populations, but has not been performed in surgical populations. Population-based management of surgical expenditures requires identification of high-cost surgical patients to allow for effective implementation of cost-saving strategies.Using 100% Medicare claims data for 2010 to 2013, we identified patients aged 65 to 99 years undergoing elective surgical procedures. We calculated price-standardized Medicare payments for the surgical episode from the index admission through 30 days after discharge. Patient-level factors associated with payments were analyzed by multivariable linear regression.Medicare patients in the highest decile of spending accounted for a disproportionate share of aggregate costs: 30% in Colectomy (COL), 22% in coronary artery bypass grafting (CABG), 19% in Total Hip Arthroplasty, and 18% in Total Knee Arthroplasty. Medicare expenditure differences between the highest and lowest deciles were because of a 5-fold difference for COL and 3-fold difference for CABG in index hospitalization cost. In contrast, for orthopedic procedures, there were 47- to 80-fold post-acute care expenditures between highest and lowest deciles. In multivariable analyses, patients with ≥3 comorbidities had significantly higher costs than healthier patients.We found that a subset of multimorbid patients was responsible for a disproportionate share of total Medicare spending, but the individual components of spending vary by procedure. These findings suggest that targeting high-cost Medicare patients (ie, hot spotting) for cost containment efforts would be a potentially effective strategy to reduce costs in surgical populations.

Objective We sought to assess the potential changes in Medicare payments and clinical outcomes of referring high-risk surgical patients to local high-quality hospitals within small geographic areas. Summary background data Previous studies have documented a benefit in referring high-risk patients to high-quality hospitals on a national basis, suggesting selective referral as a mechanism to improve the value of surgical care. Practically, referral of patients should be done within small geographic regions; however, the benefit of local selective referral has not been studied. Methods We analyzed data on elderly Medicare beneficiaries undergoing any of 4 elective inpatient surgical procedures between 2012 and 2014. Hospitals were categorized into Metropolitan Statistical Areas by zip code and stratified into quintiles of quality based on rates of postoperative complications. Patient risk was calculated by modeling the predicted risk of a postoperative complication. Medicare payments for each surgical episode were calculated. Distances between patients' home zip code and high- and low-quality hospitals were calculated. Results One quarter of high-risk patients underwent surgery at a low-quality hospital despite the availability of a high-quality hospital in their small geographic area. Shifting these patients to a local high-quality hospital would decrease spending 12% to 37% ($2,500 for total knee and hip replacement, $6,700 for colectomy, and $11,400 for lung resection). Approximately 45% of high-risk patients treated at low-quality hospitals could travel a shorter distance to reach a high-quality hospital than the low-quality hospital they received care at. Conclusions Complication rates and Medicare payments are significantly lower for high-risk patients treated at local high-quality hospitals. This suggests triaging high-risk patients to local high-quality hospitals within small geographic areas may serve as a template for improving the value of surgical care.

OBJECTIVE The aim of this study was to evaluate the rates of use and efficacy of stent placement for postoperative leak following bariatric surgery. SUMMARY OF BACKGROUND DATA Endoscopically placed stents can successfully treat anastomotic and staple line leaks after bariatric surgery. However, the extent to which stents are used in the management of bariatric complications and rates of reoperation remain unknown. METHODS Data from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program participant use files were analyzed for patients who experienced anastomotic or staple line leaks after bariatric surgery, and then evaluated for use of an endoscopically placed stent. Patient and procedure-level data were compared between those who underwent stent placement versus those who required reoperation. Multivariable logistic regression was used to compare outcomes between groups. RESULTS A total of 354,865 bariatric cases were captured in 2015 to 2016. One thousand one hundred thirty patients (0.3%) required intervention for a leak, of whom 275 (24%) were treated with an endoscopically placed stent. One hundred seven (39%) of the patients who received stents required reoperation as part of their care pathway. Patient characteristics were statistically similar when comparing leaks managed with stents to those treated with reoperation alone. Those treated with stents, however, had a higher likelihood of readmission (odds ratio 2.59, 95% confidence interval -1.59 to 4.20). CONCLUSION Placement of stents for management of leaks after bariatric surgery is common throughout the United States. The use of stents can be effective; however, it does not prevent reoperation and is associated with an increased likelihood of readmission. Both technique and resource utilization should be considered when choosing a management pathway for leaks.

To review the literature evaluating the effect of practice guidelines and decision aids on use of surgery and regional variation.The use of surgical procedures varies widely across geographic regions. Although practice guidelines and decision aids have been promoted for reducing variation, their true effectiveness is uncertain.Studies evaluating the influence of clinical practice guidelines or consensus statements, shared decision making and decision aids, or provider feedback of comparative utilization, on rates of surgical procedures were identified through literature searches of Ovid MEDLINE, EMBASE, and Web of Science.A total of 1946 studies were identified and 27 were included in the final review. Of the 12 studies evaluating implementation of guidelines, 6 reported a significant effect. Those examining overall population-based rates had mixed effects, but all studies evaluating procedure choice described at least a small increase in use of recommended therapy. Three of 5 studies examining the effect of guidelines on regional variation reported a significant reduction after dissemination. Of the 15 studies examining decision aids, 5 revealed significant effects. Many studies of decision aids reported decreases in population-based procedure rates. Nearly all studies evaluating the impact of decision aids on procedure choice reported increases in rates of less invasive procedures. Only one study of decision aids assessed changes in regional variation and found mixed results.Both practice guidelines and decision aids have been proven effective in many clinical contexts. Expanding the clinical scope of these tools and eliminating barriers to implementation will be essential to further efforts directed toward reducing regional variation in the use of surgery.
