Impact of rural hospital closures on hospitalizations and associated outcomes for ambulatory and emergency care sensitive conditions.

Purpose: The purpose of this paper is to examine the impact of rural hospital closures on age-adjusted hospitalization rates for ambulatory care sensitive condition (ACSC) and emergency care sensitive condition (ECSC) and associated outcomes, such as length of stay and in-hospital mortality in hospital service areas (HSAs) that utilized the closed hospital.

Methods: We used the State Inpatient Data from the Healthcare Cost and Utilization Project for 9 states from 2010 to 2017 and classified admissions as ACSC or ECSC. We compared age-adjusted admission rates and length of stay (LOS) for ACSC and ECSC rates and age adjusted in-hospital mortality rate for ECSC among rural ZIP codes in HSAs with a closure to rural ZIP codes in HSAs without closures. We used propensity score-weighted regression analysis and event study design.

Findings: Findings suggest that ACSC admission rates started to increase right before the closure. However, this increase levels off 2 years after closure. LOS for ACSC significantly decreased almost a year after closure. ECSC admissions showed a significant decrease for a few quarters 1 year before the closure.

Conclusions: Rural hospital closures were associated with increase in ACSC admissions right before closure and for nearly 2 years post closure as well as decrease in ECSC admissions before closure. As rural hospitals continue to close, efforts to ensure communities affected by these closures maintain access to primary health care may help eliminate increases in costly preventable hospital admissions for ACSC while ensuring access for emergency care services.
