Specialized oral nutritional supplement (ONS) improves handgrip strength in hospitalized, malnourished older patients with cardiovascular and pulmonary disease: A randomized clinical trial
Abstract
BACKGROUND & AIMS
Oral Nutritional Supplements (ONS) are used to treat malnutrition and improve clinical outcomes in malnourished patients. Poor handgrip strength (HGS) is associated with an increased risk of mortality, disability and other adverse health consequences. This analysis examined the effect of a specialized ONS on HGS and its relationship to nutritional status in hospitalized, older adults with malnutrition who were participants in the NOURISH trial.
METHODS
We enrolled older (≥65years), malnourished (Subjective Global Assessment [SGA] class B/C) adults hospitalized for cardiovascular and pulmonary events: congestive heart failure, acute myocardial infarction, pneumonia and/or chronic obstructive pulmonary disease exacerbation in a double-blind, randomized, placebo-controlled trial (NOURISH study). During hospitalization and until 90 days after discharge, participants received standard-of-care plus a high protein and beta-hydroxy-beta-methylbutyrate containing ONS (S-ONS; n = 328) or a placebo supplement (n = 324), aimed at 2 servings/day. HGS was evaluated by dynamometer at baseline, hospital discharge, day (d) 30, d60, and d90 post-discharge.
RESULTS
Post hoc, repeated measures analysis of data at discharge, d30, d60, and d90 showed significantly higher HGS in the S-ONS vs. the placebo group in the evaluable group (Least Squares Means ± Standard Error: (23.25 ± 0.25 vs. 22.63 ± 0.25, p = 0.043). At d90, there was a significant positive association between HGS…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 328 participants or records.
