Effects of the use of oral nutrition supplements on clinical outcomes among patients who have undergone surgery for hip fracture: A literature review

Abstract

AbstractOlder adults who have undergone surgery for hip fracture are often malnourished or at risk for malnutrition, and providing oral nutrition supplements is a common intervention used to help meet nutrition needs postoperatively among this population. A literature search was conducted to examine the effects of oral nutrition supplementation on postoperative outcomes among patients ≥55 years old who had undergone surgery for hip fracture. Three randomized controlled trials that met inclusion criteria are examined in this review. Findings suggest that the use of oral nutrition supplements is not associated with decreased hospital length of stay but is associated with improvements in markers of sarcopenia and functional status. Additionally, the literature implies that oral nutrition supplements containing calcium beta‐hydroxy‐beta‐methylbutyrate may have the most benefit for improving postoperative outcomes. This review concludes that oral nutrition supplement use can be incorporated as a part of routine protocols for patients who have had surgery to repair a hip fracture. However, given some inconsistent findings, future research is needed to support the inclusion of oral nutrtition supplement use in clinical practice guidelines for this population. Furthermore, future research should explore how the use of oral nutrition supplements with calcium beta‐hydroxy‐beta‐methylbutyrate compares with the use of oral nutrition supplements without this ingredient.
