BACKGROUND: Barriers to healthcare are common in the USA and may result in worse outcomes among hospital survivors of an acute coronary syndrome (ACS).
OBJECTIVE: To examine the relationship between barriers to healthcare and 2-year mortality after hospital discharge for an ACS.
DESIGN: Longitudinal study.
SETTING: Survivors of an ACS hospitalization were recruited from 6 medical centers in central Massachusetts and Georgia in 2011-2013.
PATIENTS: Study participants with a confirmed ACS reported whether they had a financial-related healthcare barrier, no usual source of care, or a transportation-related healthcare barrier around the time of hospital admission.
MEASUREMENTS: Cox regression analyses calculated adjusted hazard ratios (aHRs) for 2-year all-cause mortality for the three healthcare barriers while controlling for several demographic, clinical, and psychosocial characteristics.
RESULTS: The mean age of study participants (n = 2008) was 62 years, 33% were women, and 77% were non-Hispanic white. One third of patients reported a financial barrier, 17% lacked a usual source of care, and 12% had a transportation barrier. Five percent (n = 100) died within 2 years after hospital discharge. Compared to patients without these barriers, those lacking a usual source of care and with barriers to transportation experienced significantly higher mortality (aHRs 1.40, 95% CI 1.30 to 1.51 and 1.46, 95% CI 1.13 to 1.89, respectively). Financial barriers were not associated with all-cause mortality (aHR 0.79, 95% CI 0.60 to 1.06).
LIMITATIONS: Observational study with other unmeasured potentially confounding prognostic factors.
CONCLUSIONS: Absence of an established usual source of care and inconsistent transportation availability were associated with a higher risk for dying after an ACS. Patients with these barriers to follow-up care may benefit from more intensive follow-up and support.
