Abstract Background: The increasing burden of obesity generates significant socioeconomic impacts for individuals, populations, and national health systems worldwide. The literature on impacts and cost-effectiveness of obesity-related interventions for prevention and treatment of moderate to severe obesity indicate that bariatric surgery presents high costs associated with high effectiveness in improving health status referring to certain outcomes; however, there is a lack of robust evidence at an individual-level estimation of its impacts on multiple health outcomes related to obesity comorbidities.Methods: The study encompasses a single-centre retrospective longitudinal analysis of patient-level data using micro-costing technique to estimate direct health care costs with cost-effectiveness for multiple health outcomes pre-and post-bariatric surgery. Data from 114 patients who had bariatric surgery at the Hospital of Clinics of the University of Sao Paulo during 2018 were investigated through interrupted time-series analysis with generalised estimating equations and marginal effects, including information on patients' characteristics, lifestyle, anthropometric measures, hemodynamic measures, biochemical exams, and utilisation of health care resources during screening (180 days before) and follow-up (180 days after) of bariatric surgery.Results: The preliminary statistical analysis showed that health outcomes presented improvement, except cholesterol and VLDL, and overall direct health care costs increased after the intervention. However, interrupted time series analysis showed that the rise in health care costs is attributable to the high cost of bariatric surgery, followed by a statistically significant decrease in post-intervention health care costs. Changes in health outcomes were also statistically significant in general, except in cholesterol and LDL, leading to significant improvements in patients' health status after the intervention.Conclusions: Trends multiple health outcomes showed statistically significant improvements in patients' health status post-intervention compared to trends pre-intervention, resulting in reduced direct health care costs and the burden of obesity.

Background: Drug-eluting stents (DES) and implantable cardioverter-defibrillators (ICDs) are among the most common, and most costly, interventional therapies used in patients with cardiovascular disease. Medicare coverage decisions for DES and ICDs in 2003-2005 portended a large growth in health care costs for patients with coronary artery disease (CAD) and chronic heart failure (CHF). However, the actual fiscal impact of DES and ICDs is uncertain. Methods: We examined Medicare claims from 2003-2006 and separately identified cohorts of patients between ages 65-84 in each year diagnosed with CAD and CHF. Patients were assigned to one of 306 contiguous geographic localities (i.e., Dartmouth Atlas Hospital Referral Regions [HRRs]). For each disease group in each locality in each year, we calculated the average cost of care (including Medicare payments, supplemental insurance, and patient payments) as well as the average use rate of DES (for CAD) and ICDs (for CHF). We estimated time-series HRR-fixed-effects regression models predicting average costs, with % technology use as an independent variable. We included a measure of the annual change in costs of care for non-cardiovascular disease in each HRR to control for annual cost increases unrelated to ICDs/DES. Results: Average inflation-adjusted costs for CAD patients increased from $13,558 in 2003 to $14,215 in 2006 (p<0.001), while average costs for CHF patients increased from $18,930 in 2003 to $20,235 in 2006 (p<0.001). Time-series regressions indicated that a 1% increase in DES use among the CAD population resulted in $394 in higher mean costs (p<0.001), and 1% increased ICD use in the CHF population resulted in $627 in higher mean costs (p<0.001). In aggregate, between 2003-2006 the cost increase attributable to DES in the Medicare CAD population ages 65-84 was $4.97 billion (89% of total growth), and the cost increase in the Medicare CHF population attributable to ICDs was $893 million (29% of total growth). Conclusions: Rising use of DES and ICDs between 2003-2006 was associated with significantly higher costs for patients with CAD and CHF, respectively. Increased use of these technologies explained substantial fractions of the growth in health care costs for CAD and CHF patients during these years.
