Preoperative Risk Factor Score Predicts Malnutrition in Total Joint Arthroplasty Patients

$25.00

Malnutrition is a modifiable risk factor for poor outcomes in patients undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA). The purpose of this study is to highlight risk factors for hypoalbuminemia and develop a predictive model that identifies patients at risk for this condition before THA or TKA. The study retrospectively reviewed the National Surgical Quality Improvement Program database to analyze preoperative independent risk factors for a diagnosis of hypoalbuminemia in adult patients who underwent THA or TKA. These factors were used to create a preoperative risk model to predict hypoalbuminemia. Individuals with three or more risk factors in the seven-point model are predicted to have hypoalbuminemia in 20.4% of THA or 10.5% of TKA cases. Accurate identification of hypoalbuminemic patients may allow preoperative nutrition interventions to improve postoperative outcomes.
