    Abstract:
    This study was conducted to assess the validity and the reliability of simple tools to screen the protein-energy malnutrition (PEM) risk among the elderly population in healthcare facilities. An initial screening tool, made up of nine PEM risk factors, was previously developed to be validated. This tool was quite complex and showed low validity results. A stepwise regression analysis determined significant risk factors (P < or = 0.05) among those included in the initial tool. These were the foundation to develop two simplified screening tools. One included Body Mass Index (BMI) and % weight loss over time. The second included BMI and albumin. Both tools classified subjects in low or high PEM risk levels. In the present study, the simple tools were assessed in a sample of 142 elderly subjects divided into two categories: acute care elderly (ACE, n=72) and long-term care elderly (LTCE, n=70). The simple tools were administered by a dietetic technician and a nurse with the purpose of assessing inter-rater and test-retest reliabilities. The criterion validity of the simple tools were assessed in comparison to in-depth nutritional assessments carried out by a dietitian. The validity results were ranked between 60.5% and 91.7%. The reliability scores showed levels of agreement of 70.8% to 93.1% and kappa coefficients ranking between 0.59(+/-0.07) and 0.79(+/-0.05). Simple tools are now available for efficiently screening the PEM risk among the elderly population on a healthcare facility-wide basis.
