Will to Live in Older Nursing Home Residents: A Cross-Sectional Study in Switzerland.

Abstract

The will to live (WTL) is an important indicator of subjective well-being. It may enable a deeper understanding of the well-being of nursing home residents. To evaluate the intensity of WTL, its association with various factors, and its temporal evolution among residents ≥ 65 years old; we also aimed to compare it with proxy assessments of WTL. A cross-sectional study was conducted in five nursing homes in Switzerland. Participants with decisional capacity were asked to rate the intensity of their WTL on a single-item numerical rating scale ranging from 0-10. A short-term follow-up was conducted among a sub-sample of 17 participants after three and six weeks. Proxy assessment by residents' next of kin and professional caregivers was conducted, and inter-rater agreement was calculated. Data from 103 participants (75.7% women, 87.3 ± 8.0 years) was analyzed. The median intensity of WTL was 8. Higher WTL was significantly associated with better physical mobility and shorter duration of daily care but not with age, gender, pre-admission care setting, or prognosis. Significant independent predictors of WTL were physical mobility and provenance from rehabilitative care. In the short-term follow-up assessment, WTL remained highly stable. Intraclass correlation coefficients were moderate for residents' next of kin and nurse assistants but poor for physicians and nurses; all proxy assessments underestimated the participants' WTL. Nursing home residents expressed a very strong WTL and proxy aents underestimated residents' WTL. It seems pivotal to proactively communicate with residents about their WTL.
