RESUMO
OBJECTIVES: To propose an objective definition of vitality and to evaluate its predictive value regarding the evolution of functional ability, as well as the risk of hospitalization and mortality in very old NH residents. DESIGN: Observational study. SETTINGS: Nursing homes. PARTICIPANTS: 541 participants. MEASUREMENTS: We operationalized tree definitions of vitality (binary variables discriminating vital from non-vital individuals): Mental vitality, assessed using three items of the geriatric depression scale; Physical vitality measured through hand grip strength test; and combined vitality, which combined mental and physical vitality definitions. Outcome measures were the 1-year evolution of functional ability as measured by a scale of activities of daily living (ADL) (score from 0 to 6) and the incidence of hospitalizations and mortality (time-to-event). RESULTS: First, 204 (37.7%) residents were defined as mentally vital. Second, 139 (27.5%) residents were defined as physically vital. And 52 (9.6%) were defined as vital when combining physical and. Combined vitality was associated with a reduced risk of hospitalization compared to combined non-vitality. Physically vital residents were associated with a reduced risk of mortality. No prospective associations were found between vital and non-vital individuals on the evolution of ADL scores across the three vitality definitions. But mentally vital individuals were associated with a worsening of ADL score. CONCLUSIONS: Better combined vitality seems to be associated with a reduced risk for hospitalizations, but more studies are needed to confirm a valid measurement of vitality in people living in NH in regards to ADL and mortality.

OBJECTIVES: To gather available evidence about overtime changes on physical performance in institutionalized elderly. DESIGN, SETTING AND PARTICIPANTS: An electronic search was performed on PubMed database on May 2018. We selected articles reporting the evolution of physical performance in older adults living in care institutions. We looked for data from observational longitudinal studies; data from clinical trials were extracted only for subjects who did not receive exercise intervention. All types of performance-based tests, for upper- and/or lower-body, were scrutinized. RESULTS: Seventeen studies were reviewed; mean age varied from 78.3 to 88 years old. Fourteen studies were randomized controlled trials (RCTs), other three studies were non-randomized trials and a longitudinal observational study. Different tests assessing physical performance were examined: upper limb strength and lower limb strength, static balance, dynamic balance and mobility showed a tendency to decline over time. On average hand grip strength decreased by 2.2% per month, chair stand test by 3.5%, Berg balance scale by 2%, timed up-and-go test by 2.8%, gait speed by 2.1% and short physical performance battery by 2.8%. A minority of studies have shown an improvement in lower limb muscle strength, endurance and gait speed: in these studies, participants did not attend any kind of physical training but took part to social activities or cognitive interventions. CONCLUSION: This review shows how physical performance decreases over time in nursing home residents and quantifies their decline. However, in active controls, there was an improvement in some physical performance measures, which indicates that intervention other than exercise might prevent some loss in physical performance.
