Life‐space mobility and post‐hospitalization outcomes among older Mexican American Medicare beneficiaries

Abstract

AbstractBackgroundOlder adults with limited mobility are at an increased risk of adverse health outcomes, an outcome inadequately investigated in older Mexican Americans. We explored whether pre‐admission life‐space mobility predicts post‐hospitalization outcomes among hospitalized Mexican American Medicare beneficiaries.MethodsLife‐space mobility, using the Life‐Space Assessment (LSA), was analyzed using quartiles and 5‐point intervals. Using the Hispanic Established Populations for the Epidemiologic Study of the Elderly (HEPESE) Waves 7 and 8 data linked to Medicare claims data, 426 older Mexican Americans with at least 2 months of Medicare coverage who were hospitalized within 2 years of completing the LSA were included. Logistic and Cox Proportional regression analyses estimated the association of pre‐admission LSA with post‐hospitalization outcomes.ResultsPrior to hospitalization, 85.4% reported limited life‐space mobility. Most patients (n = 322, 75.6%) were hospitalized for medical reasons. About 65% were discharged to the community. Pre‐admission LSA scores were not associated with community discharge (Odds Ratio [OR] = 1.02, 0.95–1.10). Higher pre‐admission LSA scores were associated with 30‐day readmission (OR = 1.11, 1.01–1.22). Patients in the highest pre‐admission LSA quartile (i.e., greatest life‐space mobility) were less likely to die within 2 years after hospital discharge (OR = 0.61, 0.39–0.97) compared to those with lower pre‐admission LSA scores.ConclusionsAmong older Mexican American Medicare beneficiaries, greater pre‐admission LSA scores were associated with an increased risk of 30‐day readmission and a decreased risk of mortality within 2 years following hospitalization. Future work should further investigate the relationship between LSA and post‐hospitalization outcomes in a larger sample of Mexican American older adults.
