Modified Frailty Index Predicts Postoperative Complications Following Parastomal Hernia Repair.

Area of Science:

• Surgical outcomes research
• Patient risk stratification
• Health informatics

Background:

• The 5-factor frailty index (5-mFI) is a validated tool for predicting postoperative complications.
• Preoperative assessment of frailty can stratify patients undergoing parastomal hernia repair.

Purpose of the Study:

• To evaluate the association between the 5-factor frailty index (5-mFI) and postoperative outcomes following parastomal hernia repair.
• To determine if 5-mFI can serve as an independent predictor of complications and resource utilization.

Main Methods:

• Retrospective review of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database (2015-2020).
• Calculation of 5-mFI based on comorbidities: diabetes mellitus, congestive heart failure (CHF), hypertension, chronic obstructive pulmonary disease (COPD), and functional status.
• Analysis of 30-day overall complications, readmission, reoperation, and discharge to a care facility.

Main Results:

• A 5-mFI score of 2 or more was associated with significantly higher rates of overall, pulmonary, cardiovascular, hematologic, and renal complications.
• Higher 5-mFI scores correlated with increased 30-day readmission, reoperation, discharge to a care facility, and mortality.
• Multivariate analysis confirmed 5-mFI ≥ 2 as an independent risk factor for overall complications, pulmonary, hematologic, renal complications, readmission, and discharge to facility.

Conclusions:

• Patients undergoing parastomal hernia repair with a 5-mFI score of 2 or higher exhibit elevated risks for major complications, readmissions, and mortality.
• The 5-mFI is a valuable tool for preoperative risk stratification in patients undergoing parastomal hernia repair.
• Preoperative identification of frail patients allows for targeted interventions to mitigate adverse outcomes.
