Intensive care use and mortality among patients with ST elevation myocardial infarction: retrospective cohort study.

ABSTRACT:

Objective

To evaluate the effect of intensive care unit (ICU) admission on mortality among patients with ST elevation myocardial infarction (STEMI).

Design

Retrospective cohort study.

Setting

1727 acute care hospitals in the United States.

Participants

Medicare beneficiaries (aged 65 years or older) admitted with STEMI to either an ICU or a non-ICU unit (general/telemetry ward or intermediate care) between January 2014 and October 2015.

Main outcome measure

30 day mortality. An instrumental variable analysis was done to account for confounding, using as an instrument the additional distance that a patient with STEMI would need to travel beyond the closest hospital to arrive at a hospital in the top quarter of ICU admission rates for STEMI.
