Cost-Effectiveness of Two Nutrition Interventions in Long-Term Care

DESCRIPTION (provided by applicant): Inadequate food and fluid intake is a common problem among nursing home (NH) residents and one that can lead to under-nutrition, dehydration, weight loss, hospitalization, and even death. The most common nutrition intervention for at-risk NH residents is oral liquid nutrition supplementation, although, there is limited controlled evidence of the efficacy of supplements in promoting weight gain in NH residents. Moreover, studies show that supplements are not provided consistent with orders and residents receive little to no staff assistance to promote consumption in daily NH care practice. The result is that nutritionally at-risk NH residents with supplement orders receive few additional daily calories from supplements. Recent evidence strongly suggests that offering residents a choice among a variety of foods and fluids multiple times per day between meals coupled with assistance is effective in increasing daily caloric intake and promoting weight gain. However, the provision of the between-meal choice intervention requires significantly more staff time relative to the amount of time NH staff currently spend on between-meal nutritional care provision. A new federal regulation allows NHs to train non-nursing staff to provide feeding assistance care. Preliminary research has demonstrated that non-nursing staff trained as "feeding assistants" provide mealtime feeding assistance care that is comparable to or better than their indigenous nurse aide counterparts. Moreover, a recent demonstration project showed that these staff can be used to effectively augment nurse aide staff for mealtime feeding assistance care provision in daily care practice. The proposed translational study will utilize the federal regulation to train non-nursing staff for between-meal nutritional care delivery. Specifically, the proposed study will use a controlled, intervention design to determine the cost-effectiveness of the between-meal choice intervention relative to a usual care control group in a group of 200 residents across 4 NH sites. Residents with an order for caloric supplementation will be included in this study and randomized into either a usual care control group or a choice intervention group (100 residents per group). The usual care control group will continue to receive standard NH care for supplement or snack delivery between meals, as provided by indigenous nurse aide staff. Non-nursing staff trained as "feeding assistants" will offer residents in the intervention group a choice between supplements and other snack foods and fluids twice daily, five days per week, for 24 weeks while also providing a standardized prompting protocol to enhance intake and independence in eating. Research staff will independently document the costs of intervention implementation and compare these costs to effectiveness measures which include improvements in caloric intake, weight and quality of life. These outcomes will be independently monitored for both groups across 24 study weeks by trained research staff using standardized, validated protocols. This translational research effort will provide critical information to improve care practices in nursing homes for nutritionally at risk residents. PUBLIC HEALTH RELEVANCE: The purpose of the proposed translational research study is to evaluate the comparative cost-effectiveness of a between-meal choice nutrition intervention for improving daily caloric intake and weight status in long-stay nursing home (NH) residents. A controlled intervention design will be used wherein research staff will train nursing home staff in intervention delivery between meals in a group of 250 residents across 4 NH sites. Resident outcomes, which will be independently monitored by research staff, include changes in caloric intake, body weight and quality of life measures.
