Outcome of Acute Myocardial Infarction According to the Specialty of the Admitting Physician
Key result
Admission by a cardiologist for acute myocardial infarction was associated with a 12% lower risk of death within one year compared to admission by a primary care physician (P<0.001).

Does hospital admission by a cardiologist improve one-year survival in Medicare patients with acute myocardial infarction compared to admission by a primary care physician?

Implication
Should not yet change admission practices by specialty; leaves open whether cardiologist care causally improves survival.

Structured PICO
Does hospital admission by a cardiologist improve one-year survival in Medicare patients with acute myocardial infarction compared to admission by a primary care physician?
P
Population
8,241 Medicare patients hospitalized for acute myocardial infarction in four US states during a seven-month period in 1992, along with a broader validation cohort of 220,535 Medicare patients with AMI in 1992.
I
Intervention
Hospital admission by a cardiologist
C
Comparator
Hospital admission by a primary care physician
O
Outcome
Mortality up to one year after the myocardial infarctionhard clinical
Main Result
Effect estimate: 12% lower risk
p-value: p=<0.001
Admission of elderly patients with acute myocardial infarction by cardiologists rather than primary care physicians is associated with higher utilization of evidence-based treatments and improved one-year survival.
Cite This Study
Jollis et al. (1996) conducted an observational in Acute myocardial infarction (n=220,535). Admission by a cardiologist vs. Admission by a primary care physician was evaluated on Mortality up to one year after myocardial infarction (12% lower risk, p=<0.001). Admission by a cardiologist for acute myocardial infarction was associated with a 12% lower risk of death within one year compared to admission by a primary care physician (P<0.001).
