The Modified Five-Item Frailty Index to Predict Hand and Wrist Surgical Repair Postoperative Outcomes: An ACS-NSQIP Analysis of 11 369 Patients

Background: Hand and wrist injuries can cause painful, everyday obstacles for patients. Carefully indexing preoperative patient health conditions may better inform surgical care, leading to improved postoperative outcomes. The purpose of the present study is to evaluate if the Modified-Five Item Frailty Index (mFI-5) can accurately predict postoperative complications for hand and wrist surgical repair. Methods: A retrospective review of the American College of Surgeons’ National Surgical Quality Improvement Program database was conducted to investigate patients who underwent hand and wrist surgical repair from January 2013 to December 2019. Patient demographics, comorbidities, surgical logistics, and 30-day readmission due to postoperative complications were extracted. Surgical risk proxies including the mFI-5, age, body mass index (BMI), smoking status within 1 year, the Modified Charlson Comorbidity Index (mCCI), comorbidities, and American Society of Anaesthesiologists Physical Status Classification (ASA class) were calculated. Results: A total of 11 369 patients were included. Thirty-day readmission for total postoperative complications (n = 258) was significantly associated with all surgical risk proxies. However, age, mFI-5 > 2, mCCI > 2, comorbidities > 1, and ASA class 2/3 had the highest statistical significance ( P = 2, and ASA class 2/3 ( P = 1 (n = 224) had the highest statistical significance with age, mCCI > 2, comorbidity of 1, and an ASA class 3 ( P = Conclusions: The mFI-5 may have value in predicting 30-day readmission due to postoperative complications after surgical repair of hand and wrist injuries.
