The SAGES Bariatric Surgery Outcome Initiative

Area of Science:

• Bariatric Surgery Outcomes
• Surgical Database Analysis
• Health Services Research

Background:

• National initiatives identify centers of excellence in bariatric surgery, requiring outcome documentation.
• The Society of American Gastrointestinal Endoscopic Surgeons' (SAGES) Outcomes Initiative, a national database, was established in 1999.
• A bariatric-specific dataset was later developed in 2001 for comparative analysis.

Purpose of the Study:

• To compare bariatric surgery outcomes between the SAGES bariatric database and a national administrative database.
• To evaluate the utility of the SAGES database for benchmarking bariatric surgery performance.
• To assess data completeness and comparability between the two databases.

Main Methods:

• The study compared data from the SAGES Bariatric Outcome Initiative (2001-2004, 1,954 patients) with the University HealthSystem Consortium (UHC) database (42,847 patients).
• Key outcome measures included demographics, comorbidities, procedure type, operative time, length of stay, complications, mortality, and weight loss.
• Analysis focused on data completeness and comparability between the two national databases.

Main Results:

• Both datasets showed comparable gender distribution and high rates of Roux-en-Y gastric bypass.
• The SAGES database offered more detailed bariatric-specific information (BMI, operative time, blood loss, specific complications, weight loss).
• No statistically significant differences in perioperative complications or mortality were found between the datasets.

Conclusions:

• The SAGES Bariatric Outcome Initiative provides valuable, bariatric-specific data for benchmarking not found in administrative databases.
• The SAGES database contains richer detail on surgical outcomes and patient characteristics.
• Current utilization of the SAGES database is suboptimal, despite its potential value.
