Life-space mobility predicts nursing home admission over 6 years.

ABSTRACT: To explore the association between baseline life-space mobility and nursing home (NH) admission among community-dwelling older adults over 6 years.Using data from a prospective, observational cohort study consisting of a random sample of 1,000 Medicare beneficiaries ? 65 years of age stratified by race (African American and non-Hispanic White), sex, and rural/urban residence. Baseline life-space mobility was assessed during in-home interviews. Participants were contacted by telephone every 6 months to ascertain NH admissions, Life-Space Assessment (LSA) scores, and vital status (living or deceased). Using multivariate logistic regression, the significance and independence of the relationship of life-space mobility with NH admission were examined.Over 6 years, the odds of NH admission increased 2% for every one point lower baseline life-space score independent of previously recognized risk factors.The LSA may be a useful tool to identify older adults at risk of NH admission.

Project description:BackgroundTraditional performance-based measurements of mobility fail to recognize the interaction between the individual and their environment. Life-space (LS) forms a central element in the broader context of mobility and has received growing attention in gerontology. Still, knowledge on LS in the nursing home (NH) remains sparse. The aim of this study was to identify LS trajectories in people with dementia from time of NH admission, and explore characteristics associated with LS over time.MethodsIn total, 583 people with dementia were included at NH admission and assessed biannually for 3 years. LS was assessed using the Nursing Home Life-Space Diameter. Association with individual (age, sex, general medical health, number of medications, pain, physical performance, dementia severity, and neuropsychiatric symptoms) and environmental (staff-to-resident ratio, unit size, and quality of the physical environment) characterises was assessed. We used a growth mixture model to identify LS trajectories and linear mixed model was used to explore characteristics associated with LS over time.ResultsWe identified four groups of residents with distinct LS trajectories, labelled Group 1 (n = 19, 3.5%), Group 2 (n = 390, 72.1%), Group 3 (n = 56, 10.4%), Group 4 (n = 76, 14.0%). Being younger, having good compared to poor general medical health, less severe dementia, more agitation, less apathy, better physical performance and living in a smaller unit were associated with a wider LS throughout the study period.ConclusionFrom NH admission most NH residents' LS trajectory remained stable (Group 2), and their daily lives unfolded within their unit. Better physical performance and less apathy emerged as potentially modifiable characteristics associated with wider LS over time. Future studies are encouraged to determine whether LS trajectories in NH residents are modifiable, and we suggest that future research further explore the impact of environmental characteristics.

Project description:BACKGROUND:The purpose of this study was to examine the differences of timewise changes in life-space mobility between elderly people living alone and those living with others among community-dwelling elderly people from a day care facility with a rehabilitation service for seniors. METHODS:The present study used a longitudinal design with repeated measures every 3?months. In conformity with our inclusion criteria, this study included 233 community-dwelling elderly users of a day care facility with rehabilitation services for seniors in Japan. We analyzed the life-space assessment (LSA) scores collected at five time points (baseline, 3?months, 6?months, 9?months, and 12?months) using mixed-effects models with random intercepts and slopes over time. In the present study, the explanatory variables of interest were time, and living situation (living alone or with others). As possible confounders, we considered the following: (a) age, (b) sex, (c) social frailty, (d) physical frailty, (e) mild cognitive impairment (MCI), (f) depression, and (g) economic satisfaction. RESULTS:The mean age of participants was 78.9?years (SD?=?7.7), their mean LSA score was 60.1 points (SD?=?25.7), and 42.9% of the participants were men. After adjusting for age, gender, frailty, depression, MCI, and economic satisfaction, the mean LSA score of older adults who lived with others was significantly lower (7.42 points, 95%CI?=?-?18.30 to -?0.15, p?=?0.048) than that older adults who lived alone. DISCUSSION:Community-dwelling older adults who used a day care center with rehabilitation services and lived with others had a smaller life-space at baseline than those who lived alone. This suggests that there is a need to pay more attention to social frailty among both older adults who live alone and those who live with others. CONCLUSIONS:According to a multilevel analysis growth model, elderly persons who lived with others had significantly lower life-space mobility than those who lived alone.
