Validation of the Malnutrition Screening Tool for use in a Community Rehabilitation Program

The aim of the present study was to determine if the Malnutrition Screening Tool (MST) is valid for use within the Community Rehabilitation Program (CRP) setting. Secondary outcome measures were to assess malnutrition prevalence in the CRP population and to determine trends between malnutrition and age, body mass index (BMI) and falls history.

This study used a cross-sectional design. All clients admitted to a Melbourne metropolitan CRP during the study period had the MST completed at intake. A total of 160 participants were then selected at random and a Subjective Global Assessment (SGA) was completed by an experienced dietitian. Participants were classified as well nourished or malnourished, and this result was compared to their MST score. Data analysis was completed to determine the predictive value of the MST compared to SGA, which was expressed using sensitivity, specificity, positive and negative predictive values.

Out of the 160 participants, 34.0% were identified as malnourished. The MST achieved a sensitivity of 72.2% and a specificity of 83.8% with positive predictive value of 69.6% and negative predictive value of 85.4% compared to the SGA. Participants in the malnourished group were older and had a lower BMI (P < 0.05).

Considering the demographics and needs of the CRP population group and the predictive value of the MST compared to SGA, it can be concluded that the MST is a valid screening tool for use in this population and has relatively low burden to complete. Consequently, the MST could be included in the client initial needs identification to be completed when admitted to the program.
