Key result
Hospitalization in the United States was associated with a significantly higher 30-day all-cause readmission rate after STEMI compared to other countries (14.5% vs 9.9%, OR 1.68), though this difference was attenuated after adjusting for length of stay.
Why the study?
Does US location and care pattern increase 30-day readmission rates after STEMI compared to other countries?
Cohort (n=5,571)
Yes
Does US location and care pattern increase 30-day readmission rates after STEMI compared to other countries?
Effect estimate: OR 1.68 (95% CI 1.37-2.07)
Absolute Event Rate: 14.5% vs 9.9%
p-value: p=<0.001
Higher 30-day readmission rates after STEMI in the United States compared to other countries are largely explained by shorter initial hospital lengths of stay.

Shorter US stays may underlie higher STEMI readmissions; hypothesis-generating for LOS-targeted trials.
Kociol et al. (2012) conducted a cohort in ST-segment elevation myocardial infarction (STEMI) (n=5,571). Hospitalization in the United States vs. Hospitalization outside the United States was evaluated on 30-day postdischarge all-cause hospital readmission (OR 1.68, 95% CI 1.37-2.07, p=<0.001). Hospitalization in the United States was associated with a significantly higher 30-day all-cause readmission rate after STEMI compared to other countries (14.5% vs 9.9%, OR 1.68), though this difference was attenuated after adjusting for length of stay.
