Acute Care Utilization and Costs Up to 4 Years After Index Sleeve Gastrectomy or Roux-en-Y Gastric Bypass
Hospital Use and Costs for Up to 4 Years After Sleeve Gastrectomy or Gastric Bypass Surgery: A National Insurance Data Study
AI simplified
Abstract
The matched cohort included 4263 sleeve gastrectomy (SG) and 4520 Roux-en-Y gastric bypass (RYGB) patients.
- SG patients had a lower risk of emergency department visits (adjusted hazard ratio of 0.90) and inpatient stays (adjusted hazard ratio of 0.80) compared to RYGB patients.
- The reduced risk for SG was particularly evident for complications related to digestive system diagnoses, with adjusted hazard ratios of 0.68 for ED visits and 0.61 for inpatient stays.
- In the first year post-surgery, SG patients had lower odds of high acute care costs (adjusted odds ratio of 0.77) compared to RYGB patients.
- Cost differences between SG and RYGB diminished by years 3 and 4, with year-4 acute care costs showing an adjusted odds ratio of 1.10.
- SG may be associated with fewer complications requiring emergency care and hospitalization, particularly for digestive-related issues.
