Abstract:
OBJECTIVE:To examine the relationship between estimated travel time to admitting hospital and mortality for veterans with acute ischemic stroke, controlling for patient demographic, clinical, facility-level variables, as well as select in-hospital treatments and procedures. METHODS:A longitudinal observational population-based study. Information on all veterans discharged from a Veterans Administration Medical Center (VAMC) with an ischemic stroke diagnosis between October 1, 2006 and September 30, 2008 were examined. A total of 10,430 patients met the inclusion criteria for the study. Unadjusted differences between patients who died during the hospital stay versus those patients who were discharged alive, used χ analyses or Student t tests, as appropriate. Multivariable logistic regression was used to control for confounding effects of patient, treatment, and facility characteristics to examine the relationship between travel time and the bivariate outcome of in-hospital mortality. RESULTS:Travel time to the admitting VAMC, our primary variable of interest regarding the effect on in-hospital mortality, after adjusting for the patient, treatment, and facility characteristics showed that longer travel times significantly increased the odds of in-hospital mortality. Travel times ≥ 90 minutes had increased odds of in-hospital mortality (OR=1.476; 95% CI, 1.067-2.042) as compared with <30 minutes. CONCLUSIONS:Even after adjusting for the confounding effects of patient, treatment, and facility characteristics, travel time from home to admitting VAMC was significantly associated with in-hospital mortality.
