Protein‐energy malnutrition is both prevalent and costly within the inpatient rehabilitation population. Registered dietitians play a key role in identifying, diagnosing, and treating protein‐energy malnutrition. Handgrip strength has been shown to correlate with clinical outcomes, including malnutrition. Reduced handgrip strength is included as a criterion in national and international consensus guidelines of malnutrition diagnoses for functional changes. However, limited research and quality improvement projects have reported on its actual use in the clinical setting. The purpose of this quality improvement project was to (1) implement handgrip strength testing into dietitian care on three inpatient rehabilitation units to allow dietitians to identify and treat nutrition‐related muscle function losses and (2) evaluate the feasibility, clinical utility, and clinical impact of this project. This quality improvement educational intervention demonstrated that handgrip strength is feasible, does not impact dietitian efficiency, and is clinically useful. Dietitians reported three areas in which handgrip strength provided value: assessing nutrition status, motivating patients, and monitoring responses to nutrition interventions. Specifically, they were able to shift away from focusing solely on change in weight to focusing on functional ability and strength. Although outcome measures demonstrated favorable outcomes, the results must be interpreted cautiously because of the small sample and pre‐post uncontrolled design. Further high‐quality research is required to provide more in‐depth information on the utility and limitations of handgrip strength as an assessment, motivational, and monitoring tool for clinical dietetics.
