Association Between Preoperative Malnutrition and Postoperative Delirium After Hip Fracture Surgery in Older Adults

Abstract

This is the first study in a Western population showing that risk of malnutrition and overt malnutrition, as assessed using the MNA-SF, are independent predictors of postoperative delirium. Accordingly, nutritional status should be assessed in individuals with hip fracture before surgery to determine risk of developing delirium.

Preoperative prognostic nutritional index predicts postoperative delirium in elderly patients after hip fracture surgery

“…14 Another study by Mazzola et al showed that the risk of malnutrition and overt malnutrition were significant predictors for POD after hip fracture surgery. 15 Accordingly, they suggested that nutritional status assessment should be performed to help predict POD development. 15 However, few studies have reported their association on clinical outcomes.…”

Goals of surgery and assessment tools for elderly patients referred for cardiac and noncardiac surgery

“…Nutritional status requires particular attention in that it has been identified as one of the most sensitive markers of negative outcome; an inadequate nutritional status is a biological signal not so much (and not only) of insufficient food intake but rather of a poor homeostatic reserve. This also explains its role as an independent risk factor of post-procedural mortality [8].…”

Prolonged hospital stay before hip fracture surgery in the elderly: a single parameter but multiple roles

“…Indeed, some mistakes are avoidable, such as the inappropriate use of antihypertensive medications, which often leads to an increased risk of hip fracture occurrence [7]. Other conditions are potentially preventable, e.g., a poor nutritional status, which was associated with the occurence of post-operative delirium in a recent study [8]. Nutritional markers were also used to predict the risk of 30-day readmission among patients hospitalized for hip fracture: according to Stone et al prealbumin, albumin, total protein, and vitamin D levels represent the core part of a statistical model to predict 30-day readmissions [9].…”
