Surgical Management of Obesity in Brazil: Proposal for a Value-Based Healthcare Model and Preliminary Results.

OBJECTIVES: To describe the implementation and 1-year results of a value-based bariatric surgery program in Brazil. METHODS: The study was conducted at a private hospital in São Paulo, Brazil (Hospital Alemão Oswaldo Cruz). A value-based healthcare program was implemented by designing an episode of care for eligible patients and developing a bundled payment model in which a single payment was made for the bariatric surgery covering the preoperative workup and ending 30 days after discharge. Assessment of outcomes included complication rate, hospital length of stay, intensive care admissions, reoperations, readmissions, and visits to the emergency department in the 30-day postoperative period. The results were compared with real-world evidence retrieved from a Brazilian private insurance database containing information on bariatric procedures performed in similar institutions (benchmark group). RESULTS: Eighty-three patients were enrolled in the value-based healthcare program (80.7% women; 18.0% with type 2 diabetes mellitus; 31.0% with high blood pressure). The mean age was 40.9 years, and body mass index was 42.1 kg/m2. The outcomes recorded in the benchmark group versus the value-based healthcare group involved complication rate, 2.6% versus 1.4% (P = 0.69); length of stay, 2.5 versus 2.0 days (P = 0.0001); intensive care admissions, 4.0% versus 1.2% (P = 0.31); emergency care visits, 15.0% versus 6.0% (P = 0.04); and readmissions, 2.3% versus 0 (P = 0.35), with an estimated cost reduction of 7.1%. CONCLUSIONS: These initial results showed favorable surgical and 30-day outcomes, demonstrating the benefits of a value-based approach for the surgical management of obesity and its comorbidities.

Laparoscopic vs open colorectal surgery: Economic and clinical outcomes in the Brazilian healthcare.

Laparoscopic surgery has become the preferred surgical approach of several colorectal conditions. However, the economic results of this are quite controversial. The degree of adoption of laparoscopic technology, as well as the aptitude of the surgeons, can have an influence not only in the clinical outcomes but also in the total procedure cost. The aim of this study was to evaluate the clinical and economic outcomes of laparoscopic colorectal surgeries, compared to open procedures in Brazil.All patients who underwent elective colorectal surgeries between January 2012 and December 2013 were eligible to the retrospective cohort. The considered follow-up period was within 30 days from the index procedure. The outcomes evaluated were the length of stay, blood transfusion, intensive care unit admission, in-hospital mortality, use of antibiotics, the development of anastomotic leakage, readmission, and the total hospital costs including re-admissions.Two hundred eighty patients, who met the eligibility criteria, were included in the analysis. Patients in the laparoscopic group had a shorter length of stay in comparison with the open group (6.02 ±â€Š3.86 vs 9.86 ±â€Š16.27, P < .001). There were no significant differences in other clinical outcomes between the 2 groups. The total costs were similar between the 2 groups, in the multivariate analysis (generalized linear model ratio of means 1.20, P = .074). The cost predictors were the cancer diagnosis and age.Laparoscopic colorectal surgery presents a 17% decrease in the duration of the hospital stay without increasing the total hospitalization costs. The factors associated with increased hospital costs were age and the diagnosis of cancer.

Real-world evidence of health outcomes and medication use 24 months after bariatric surgery in the public healthcare system in Brazil: a retrospective, single-center study.

OBJECTIVES: The number of bariatric procedures has significantly increased in Brazil, especially in the public Unified Health System. The present study describes health outcomes and medication use in obese patients treated in a major hospital that performs publicly funded surgery in Brazil. METHODS: A retrospective, single center study was conducted to collect real-world evidence of health outcomes and medication use in 247 obese patients (female, 82.2%) who underwent open Roux-en-Y gastric bypass. Changes in weight and body mass index (BMI), presence of apnea, hypertension, and type 2 diabetes (T2D), and medication use (hypertension, diabetes, and dyslipidemia) were assessed preoperatively and up to 24 months postoperatively. The mean cost of medications was calculated for the 12-month preoperative and 24-month postoperative periods. RESULTS: During the surgery, the mean age of patients was 43.42 years (standard deviation [SD], 10.9 years), and mean BMI was 46.7 kg/m2 (SD, 6.7 kg/m2). At 24 months, significant declines were noted in weight (mean, -37.6 kg), BMI (mean, -14.3 kg/m2); presence of T2D, hypertension, and apnea (-29.6%, -50.6%, and -20.9%, respectively); and number of patients using medications (-66.67% for diabetes, -41.86% for hypertension, and -55.26% for dyslipidemia). The mean cost of medications (total costs for all medications) decreased by >50% in 12-24 postoperative months compared to that in 12 preoperative months. CONCLUSION: Roux-en-Y gastric bypass successfully reduced weight, BMI, and comorbidities and medication use and cost at 24 months in Brazilian patients treated in the public Unified Health System.

Healthcare Utilization and Costs Reduction after Radiofrequency Ablation For Atrial Fibrillation in the Brazilian Private Healthcare System.

BACKGROUND: Atrial fibrillation (AF) is the most common arrhythmia worldwide, with significantly associated hospitalizations. Considering its growing incidence, the AF related economic burden to healthcare systems is increasing. Healthcare expenditures might be substantially reduced after AF radiofrequency ablation (AFRA). OBJECTIVE: To compare resource utilization and costs before and after AFRA in a cohort of patients from the Brazilian private healthcare system. METHODS: We conducted a retrospective cohort study, based on patients' billing information from an administrative database. Eighty-three adult patients who had an AFRA procedure between 2014 and 2015 were included. Healthcare resource utilization related to cardiovascular causes, including ambulatory and hospital care, as well as its costs, were analyzed. A p-value of less than 0.05 was considered statistically significant. RESULTS: Mean follow-up was 14.7 ± 7.1 and 10.7 ± 5.4 months before and after AFRA, respectively. The 1-year AF recurrence-free rate was 83.6%. Before AFRA, median monthly total costs were Brazilian Reais (BRL) 286 (interquartile range [IQR]: 137-766), which decreased by 63.5% (p = 0.001) after the procedure, to BRL 104 (IQR: 57-232). Costs were reduced both in the emergency (by 58.6%, p < 0.001) and outpatient settings (by 56%, p < 0.001); there were no significant differences in the outpatient visits, inpatient elective admissions and elective admission costs before and after AFRA. The monthly median emergency department visits were reduced (p < 0.001). CONCLUSION: In this cohort, overall healthcare costs were reduced by 63.5%. A longer follow-up could be useful to evaluate if long-term cost reduction is maintained.

Effectiveness and Safety of Bariatric Surgery in the Public Healthcare System in Brazil: Real-World Evidence from a High-Volume Obesity Surgery Center.

BACKGROUND: This study aimed to evaluate the waiting time, safety, and effectiveness of bariatric surgery based on real-world data. METHODS: This is a noninterventional, noncomparative, and retrospective study with 300 morbidly obese patients who had undergone open Roux-en-Y surgery. RESULTS: The procedure was found to be very safe, with low rates of overall complications (10.7%). Approximately 48.4% of the patients had reached a BMI <30 mg/kg2 at 12 months after surgery, while 6% were still classified as morbidly obese (BMI >40 mg/kg2). Comorbidity resolution was over 90% for all conditions, except for cardiovascular disease, which showed a 40% resolution. The mean number of drugs taken also decreased at 12 months after surgery. CONCLUSIONS: Bariatric surgery was found to be effective in weight reduction and in the resolution of comorbidities.
