Introduction: Access to bariatric surgery can vary significantly based on geographic and institutional factors, affecting patient outcomes. This study investigates the distribution of Sleeve Gastrectomy (SG) and Roux-en-Y Gastric Bypass (RYGB) across the United States, utilizing the Nationwide Inpatient Sample (NIS) from 2017 to 2021.
Methods: A comparative analysis was performed using NIS data for 1136 SG and 1427 RYGB patients. Regional distribution was categorized according to U.S. Census Bureau divisions (Northeast, Midwest, South, West). Hospital characteristics were classified by size and teaching status. Data analysis included chi-square tests and logistic regression models to identify significant regional and institutional trends.
Results: Both SG and RYGB were most commonly performed in the South (SG: 39.31%, RYGB: 36.18%). The majority of surgeries occurred in urban teaching hospitals (SG: 79.6%, RYGB: 83.8%). Large hospitals accounted for 56.99% of SG and 48.34% of RYGB cases. Elective admissions comprised 59.62% of SG and 55.84% of RYGB cases, indicating a preference for planned surgical interventions.
Conclusion: Bariatric surgeries are primarily performed in urban teaching hospitals, with a notable regional concentration in the South. These insights highlight the importance of regional healthcare resources and their impact on the accessibility of bariatric procedures.
