Brazilian national bariatric registry - pilot study

Area of Science:

• Metabolic and Bariatric Surgery
• Health Informatics
• Surgical Quality Improvement

Background:

• Brazil is a global leader in bariatric surgery, yet lacks comprehensive data on procedure volume and quality.
• Implementing a standardized data registry is crucial for monitoring care and improving patient outcomes.
• This study details the initial implementation and evaluation of a Bariatric Surgery Data Registry in Brazil.

Purpose of the Study:

• To evaluate the implementation of a prospective Bariatric Surgery Data Registry in Brazil.
• To establish a system for monitoring the quality of care in bariatric surgery.
• To collect data on patient demographics, surgical procedures, and outcomes.

Main Methods:

• A prospective, internet-based registry was developed in collaboration with Dendrite Clinical Systems Ltd.
• Data was collected from seven high-volume centers with a commitment to data entry.
• The registry's performance was evaluated over a three-year period post-implementation.

Main Results:

• 1,363 bariatric procedures performed by 17 surgeons were registered.
• The patient cohort (average age 39, BMI 41.5kg/m²) predominantly comprised females (67.2%) with high rates of comorbidities (34.5% diabetes, 40.1% hypertension).
• Roux-en-Y gastric bypass (79.3%) was the most common procedure, with a low complication rate (0.97%) and short hospital stay (2.03 days); one-year total body weight loss reached 33.3%.

Conclusions:

• The registry successfully captured data aligning with international bariatric surgery profiles.
• Low postoperative data entry remains a significant challenge impacting comprehensive follow-up.
• The project provides valuable insights for advancing data collection and understanding the safety and effectiveness of bariatric surgery in Brazil.
