Bariatric surgery. Analysis of hospital admissions for obesity in the Brazilian Public Health System (SUS) in Sao Paulo

Abstract

PURPOSE:To characterize the comorbidities associated with hospitalizations for obesity and the relationship of these co-morbidities with bariatric surgery and hospitalization costs during the period between 2000 and 2010 in Sao Paulo that were financed by the Brazilian Public Health System (SUS). METHODS:We used data from the Hospital Information System of the Unified Health System (SIH-SUS) for selected individuals hospitalized for obesity according to International Classification of Diseases (ICD10). RESULTS:The total cost of hospitalizations was approximately two million dollars, with 67% of the total cost for bariatric and reconstructive surgery. Women accounted for 87% of hospitalizations, and 77% of subjects were aged between 30 and 59 years; the main comorbidity found was hypertension, and the procedures performed were bariatric surgery and reconstructive surgery (postbariatric surgery). CONCLUSION:Obesity is a major public health problem that affects people of productive age, causing high costs of hospitalization, which reinforces the requirement for preventive interventions beginning from childhood.

Impacts of bariatric surgery in health outcomes and health care costs in Brazil: Interrupted time series analysis of multi-panel data

“…In Brazil, bariatric surgery was included in the list of procedures for treating moderate to severe obesity within the Brazilian Unified Health System (Sistema Unico de Saude, SUS) in 1999, therefore being accessible to eligible patients free of charge in public hospitals throughout the country [38,39]. There have been increasing trends in the adoption of bariatric surgery in treating obesity, especially among young females [38], and results of previous studies have shown low mortality risk and high effectiveness of the surgery [24,38,[40][41][42][43][44].…”

Impacts of bariatric surgery on costs and health outcomes of patients in Brazil: Interrupted time series analysis of multi-panel data

“…38,39 There has been increasing trends in adoption of bariatric surgery throughout the public facilities, especially among young females 38 , and results of previous studies have shown low mortality risk and high effectiveness of the surgery in the country. 24,38,[40][41][42][43][44] To date, most studies focusing on assessment of costs and effectiveness of bariatric surgery in Brazil and other countries have been based on limited sample size and/or single health outcome 5,6,23,38 , or relied on modelling of future outcomes. There is limited evidence including multiple anthropometric, hemodynamic and biochemical parameters of patients 20,22,45 , especially using longitudinal data before and after bariatric surgery 27,46 .…”

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

“…Brazilian health authorities estimate a prevalence of 16.8% for obesity within the Brazilian population. Therefore, an effective approach to manage obesity should be implemented, and bariatric surgery has proven to be a therapeutic option for long-term weight control in morbidly obese patients [1–5]. …”
