Abstract
INTRODUCTION
Residents in long-term institutional care (LTIC) settings are at risk of malnutrition, sarcopenia, and frailty. In the Older Persons Exercise and Nutrition (OPEN) randomized study, the impact of exercise and nutrition was analyzed. This secondary analysis focused on caregiver time (CGT).
METHODS
The 3-month intervention included repeated sit-to-stand exercises and two protein-enriched supplements daily. CGT was assessed in both dementia and somatic units using the Resource Utilization in Dementia instrument. Non-linear methods were applied due to skewed data.
RESULTS
The sample consisted of 102 persons (intervention group [IG] n = 52, control group [CG] n = 50). CGT in the IG was significantly lower at follow-up, adjusted for baseline CGT, in the dementia units, that is, 55 min/day and resident, compared to 83 min/day in the CG (odds ratio 0.668 [0.473–0.945]; p = 0.022).
DISCUSSION
A structured exercise and nutrition program was associated with reduced CGT in the dementia, but not the somatic, LTIC units.
CLINICAL TRIAL REGISTRATION
This study has been registered with the number protocol of ClinicalTrials.gov Identifier: NCT02702037.
Highlights
- Residents in long-term institutional care settings risk malnutrition, sarcopenia and frailty.
- Older Persons Exercise and Nutrition (OPEN) is a program including exercise and nutrition.
- Caregiver time (CGT) is a heavy cost-driver in long-term institutional care.
- The OPEN-program reduced CGT in the dementia units.
