Effectiveness of Implementation of an Enhanced Recovery Program in Bariatric Surgery

Area of Science:

• Surgical Outcomes
• Patient Recovery Protocols
• Health Economics

Background:

• Enhanced Recovery After Surgery (ERAS) protocols are increasingly adopted in bariatric surgery, but implementation varies.
• Specific perioperative challenges in bariatric surgery necessitate evaluating ERAS effectiveness.
• This study investigates the impact of ERAS on key outcomes in bariatric procedures.

Purpose of the Study:

• To assess the effectiveness of ERAS protocols in bariatric surgery.
• To quantify the impact of ERAS on length of stay, cost, and readmission rates.
• To increase awareness of ERAS benefits in this patient population.

Main Methods:

• A retrospective analysis comparing pre-ERAS and post-ERAS cohorts of bariatric surgery patients.
• Statistical methods included Poisson regression for length of stay and logistic regression for readmissions.
• Quantile regression was used to analyze cost differences.

Main Results:

• The post-ERAS group (1124 procedures) showed a shorter median hospital stay (1 day less) and lower median cost ($2000 less) compared to the pre-ERAS group (680 procedures).
• ERAS implementation was associated with a 28% decrease in length of stay (IRR=0.72, P<0.001) and a $2230 reduction in cost (P<0.001).
• The risk of 30-day unplanned readmissions was significantly lower in the post-ERAS group (OR=0.48, P<0.001).

Conclusions:

• Enhanced Recovery After Surgery programs are valuable in bariatric surgery.
• ERAS protocols demonstrate significant benefits for patient recovery and health system efficiency.
• The findings support wider adoption of ERAS in bariatric procedures.
