What are the most important variables in predicting 30-day mortality following primary total hip arthroplasty using an artificial neural network model?
An artificial neural network model identified preoperative INR, age, BMI, operative time, and preoperative hematocrit as the most important predictors of 30-day mortality following primary total hip arthroplasty.
PURPOSE: The purpose is to utilize an artificial neural network (ANN) model to determine the most important variables in predicting mortality following total hip arthroplasty (THA). METHODS: Patients that underwent primary THA were included from a national database. Demographic, preoperative, and intraoperative variables were analyzed based on their contribution to 30-day mortality with the use of an ANN model. RESULTS: The five most important factors in predicting mortality following THA were preoperative international normalized ratio, age, body mass index, operative time, and preoperative hematocrit. CONCLUSION: ANN modeling represents a novel approach to determining perioperative factors that predict mortality following THA.

Fassihi et al. (2021) conducted a cohort in Primary total hip arthroplasty for osteoarthritis (n=77,145). Patient and surgical risk factors vs. Reference populations was evaluated on 30-day mortality. An artificial neural network model identified preoperative INR, age, BMI, operative time, and preoperative hematocrit as the top five most important predictors of 30-day mortality following primary total hip arthroplasty.
