摘要
Objectives: There are urban-rural geographic health disparities in intracerebral hem-orrhage (ICH) outcomes. However, there is limited data regarding the relationship between intensive care (ICU) availability and ICH outcomes. We examined whether ICU availability was a significant contributor to ICH outcomes by US geographic region. Materials and methods: We used de-identified Medicare inpatient datasets from January 2016 to December 2019 and identified all index ICH admissions, strat-ifying by ICU care received during the hospitalization. Distributions of teaching hospital status, quartile of ICH volume, hospital urban-rural designation, and ICU availability were obtained using chi-square test. Propensity-score matching was uti-lized to compare outcomes of more favorable outcome, inpatient mortality, and 30 -day all-cause readmissions by ICU availability at each hospital. Results: Out of a total of 119,891 hospitalizations for ICH, 66,306 (55.3%) received ICU-level care. Of hospitals that treated at least one ICH, 42.6% did not provide ICU level care for any ICH admission during the study period. Teaching hospitals (48.0% vs 7.0%; p<0.0001), hospitals with higher ICH case volumes (p<0.0001) and in larger metro-politan areas (p<0.0001) were more likely to have an ICU available. Propensity score-matched models showed that hospital ICU availability was associated with a lower likelihood of inpatient mortality (29.4% vs 33.7%; p=0.0016) Conclusions: Rural-urban disparities in ICH outcomes are likely multifactorial, but ICU availability likely contributes to the disparity. Additional studies are necessary to elucidate other contributing mechanisms.
