Nutritional Status and Its Modifications After Hip Replacement

Prognostic Potential of the Preoperative Nutritional Status and Its Postoperative Variation in Patients Undergoing Hip Arthroplasty

Data literature lacks of evidence concerning the variation of the nutritional status in patients undergoing hip surgery, thus preventing an effective application a nutritional support program. It is therefore necessary to start identifying the clinical steps (pre-operative and post-operative) that may be defined as critical control points for malnutrition. The observation should foresee the identification of nutritional status indicators, such as weight, hemoglobin, albumin, food intake, and others that might affect a proper recovery. This study aims to investigate the prognostic nutritional factors that might influence clinical outcomes, and their variation in relation to hospitalization and rehabilitation periods.

Data literature lacks of evidence concerning the variation of the nutritional status in patients undergoing hip surgery, thus preventing an effective application a nutritional support program. It is therefore necessary to start identifying the clinical steps (pre-operative and post-operative) that may be defined as critical control points for malnutrition. Patients undergoing hip surgery would be enrolled before the surgical operation and would be evaluated three times: preoperative, postoperative, and after discharge. The observation should foresee the identification of nutritional status indicators, such as weight, hemoglobin, albumin, food intake, and others that might affect a proper recovery. This study aims to investigate the prognostic nutritional factors that might influence clinical outcomes, and their variation in relation to hospitalization and rehabilitation periods.
