Background: Older 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. Methods: Life-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. Results: Prior 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. Conclusions: Among 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.
