ABSTRACT
BACKGROUND: The prevalence of malnutrition in older persons depends on the healthcare setting. In recent years, hospital-based case management programs (CM Programs) targeting individuals in the community with chronic multimorbidity and high use of hospital resources (admissions or emergency visits) have been developed in many countries to reduce the need for complex health care. The objective of this study was to assess the prevalence of risk of malnutrition, using the Short Form of the Mini-Nutritional assessment, of community dwelling patients included in a chronic CM Program. Factors associated with malnutrition risk were also explored. METHODS: Patients included in a hospital-based integrated CM Program for older persons at high risk for hospital readmission after an index admission were studied. MNA-SF was used at program inclusion to assess the risk of malnutrition. An array of factors potentially associated with malnutrition were explored (including feeding route, use of dental prosthesis, dysphagia, consistency of foods, specific therapeutic diets, use of oral nutritional supplements, polypharmacy, falls, and other diseases and geriatric syndromes). RESULTS: 791 participants were included, mean age 79.8 years, 50.1% females. Risk of malnutrition was present in 44.9%. Participants at risk of malnutrition were more frequently female, had a lower BMI, were less likely to be fed orally and used more nutritional supplements. They also had a higher prevalence of dysphagia, needing changes in food consistency or using specific therapeutic diets, and had dementia or cancer more frequently. They also showed a higher need for palliative care. CONCLUSIONS: Risk of malnutrition in patients included in a CM Program is higher than in non-selected community dwelling older individuals. This information may help inform screening policies in similar populations at risk of hospital readmission.
