Factors Associated With Weight Loss, Low BMI, and Malnutrition Among Nursing Home Patients: A Systematic Review of the Literature

Bruce K. Tamura; Christina Bell; Kamal Masaki; Elaine J. Amella

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.

Outcomes of polypharmacy in nursing home residents.

This article provides a comprehensive review of the outcomes of polypharmacy in nursing homes. Our review had some limitations. First, we only included studies beginning in 1990, and significant earlier studies are not included. Only English language articles were included. We only researched studies from MEDLINE, and may have missed studies based on our search terms and search tools. There are many definitions of polypharmacy in the literature, including number of medications or inappropriate medications. In this review, we defined polypharmacy as a high number of medications, but not inappropriate medications. It was not surprising that polypharmacy was consistently associated with an increased number of potentially inappropriate drugs. The majority of studies were viewed showed that polypharmacy was associated with increased ADEs, increased DDIs, and increased hospitalizations. We were surprised that polypharmacy was not consistently linked with falls, fractures, and mortality. For the mortality studies, it has been postulated that perhaps some patients receiving 10 or more medications may have been moribund or receiving end-of-life or hospice care. It is possible that the number of medications is not as important as the number of potentially in appropriate drugs. There need to be more studies on these outcomes, using different definitions of polypharmacy. Polypharmacy was associated with increased costs. The drug-related morbidity and mortality, including those resulting from inappropriate medications and increased staff time, led to increased costs. Use of consultant pharmacists has been shown to decrease polypharmacy costs.

OBJECTIVE To examine the effect of intervention by geriatric medicine fellows and a geriatrician on medication cost among long term care residents with polypharmacy. DESIGN Interventional study. SETTING A single hospital-affiliated long term care facility. PARTICIPANTS Long term care residents with polypharmacy, defined as being on 9 or more medications. INTERVENTION Medication lists of all nursing home residents were reviewed in October 2007 by geriatric medicine fellows and a faculty geriatrician using the 2003 Beers Criteria and the Epocrates online drug-drug interaction program. Recommendations for each resident were prepared and discussed directly with their primary physicians, who made the final decisions regarding medication discontinuation or taper. MEASUREMENTS Mean monthly costs (derived from current retail prices) for overall as well as scheduled and pro re nata (PRN) medications were compared before and after the intervention. Estimated reduction in nursing administration time and cost were calculated based on published literature on medication administration time and nursing labor costs. RESULTS Seventy-four (46.3%) of 160 residents were on 9 or more medications. Four residents died or were discharged before the intervention, leaving a final sample of 70 residents for the intervention. After the intervention, mean monthly medication costs per resident significantly decreased; overall medications, from

42.43 (P < .0001). Gastrointestinal medications demonstrated the highest cost savings of all medication categories (eg, promethazine and proton pump inhibitors), followed by central nervous system-active medications (including benzodiazepines and fluoxetine), then analgesics and diabetes medications. CONCLUSION This polypharmacy reduction intervention by physicians used readily available tools, demonstrated a significant decrease in medication-related costs, and provided training in the core competencies of practice-based learning and improvement and systems-based practice to geriatric medicine fellows in long term care.

Weight loss and poor nutrition have been important considerations in measuring quality of nursing home care since 1987. Our purpose was to examine, synthesize, and provide a systematic review of the current literature on the prevalence and definitions of nutritional problems in nursing home residents. In the fall of 2011, we performed MEDLINE searches of English-language articles published after January 1, 1990. Articles were systematically selected for inclusion if they presented prevalence data for general nursing home populations on at least one of the following: weight loss, low body mass index, Mini-Nutritional Assessment or other measure of malnutrition, poor oral intake, or dependency for feeding. Data on each study, including study author, year, setting, population, type of study (study design), measures, and results, were systematically extracted onto standard matrix tables by consensus by a team of two fellowship-trained medical school faculty geriatrician clinician-researchers with significant experience in long term care. The MEDLINE search yielded 672 studies plus 229 studies identified through related citations and reference lists. Of the 77 studies included, 11 articles provided prevalence data from the baseline data of an intervention study, and 66 articles provided prevalence data in the context of an observational study of nutrition. There is a wide range of prevalence of low body mass index, poor appetite, malnutrition, and eating disability reported among nursing home residents. Studies demonstrate a lack of standardized definitions and great variability among countries. Of all the measures, the Minimum Data Set (MDS) weight loss definition of ≥5% in 1 month or ≥10% in 6 months had the narrowest range of prevalence rate: 6% to 15%. Weight loss, as measured by the MDS, may be the most easily replicated indicator of nutritional problems in nursing home residents for medical directors to follow for quality-improvement purposes. Additional studies are needed, reporting the prevalence of the MDS weight loss definition among international nursing home residents.
