BACKGROUND: Weight loss and poor nutrition are important quality measures in long term care. Long term care professionals need to identify factors associated with weight loss and poor nutrition to target high-risk patients.
METHODS: The authors systematically searched Medline and CINAHL databases and included English language studies with more than 100 subjects analyzed, published after January 1, 1990, with data on factors associated with at least one of the following: weight loss, low body mass index (BMI), low Mini-Nutritional Assessment (MNA) score, or other standard measure of malnutrition. Data from all studies were systematically extracted onto a matrix table. The Critical Appraisal Skills Programme (CASP) questions were used to compare the quality of evidence extracted. Data from each article were then sorted and arranged into tables of factors associated with weight loss, low BMI, and malnutrition.
RESULTS: Sixteen studies met the inclusion criteria for the review. The factors most consistently associated with weight loss were depression, poor oral intake, swallowing issues, and eating/chewing dependency. Staffing factors were associated with weight loss in most studies. The factors most consistently associated with low BMI included immobility, poor oral intake, chewing problems, dysphagia, female gender, and older age. The factors most consistently associated with poor nutrition included impaired function, dementia, swallowing/chewing difficulties, poor oral intake, and older age.
CONCLUSION: Potentially modifiable factors consistently associated with increased likelihood of weight loss, low BMI, or poor nutrition included depression, impaired function, and poor oral intake. Nursing home medical directors may wish to target quality improvement efforts toward patients with these conditions who are at highest risk for weight loss and poor nutrition.
