How strong is the will-to-live in frail older persons? A survey study in acute geriatric wards and nursing homes in Belgium.

Introduction: Will-to-live is defined as the psychological expression of one's commitment to life and the desire to continue living. It is an important indicator of subjective wellbeing. This study aimed to assess the will-to-live in frail older hospitalized patients and nursing home residents as well as to evaluate its association with physical frailty, tiredness of life, depression and wish-to-die.

Methods: Between March and September 2021, we interviewed 186 older adults in six nursing homes and two acute geriatric wards across Belgium. Will-to-live was assessed using a single-item numeric rating scale from 0 to 5. A linear regression analysis was performed to assess the association between will-to-live and frailty (Clinical Frailty Scale) with adjustment for age, gender and setting. Mann-Whitney U test was used to evaluate the association between will-to-live and depression, tiredness of life and wish-to-die.

Results: Mean age was 85 (± 6.2) years. Mean score on the Clinical Frailty Scale was five (± 1.5) and four on the will-to-live (± 1.3). No statistical significant association was found between will-to-live and age (p = 0.991), gender (p = 0.272), setting (p = 0.627) and frailty (p = 0.629). Multiple linear regression showed no significant association with Clinical Frailty Scale (p = 0.660), after adjustment for age, gender and setting. Will-to-live was negatively associated with tiredness of life (p = 0.020) and wish-to-die (p < 0.001), but not with depression (p = 0.186).

Discussion: Both nursing home residents and older hospitalized patients expressed a strong or very strong will-to-live. Will-to-live was not associated with physical frailty as measured by the Clinical Frailty Scale. Nursing home residents with a weak will-to-live were more likely to have depressive symptoms. Most nursing home residents with a wish-to-die had also a low will-to-live, although some residents had both a high will-to-live and wish-to-die.
