The following article is a part of conference coverage from the American College of Cardiology’s 71st Annual Scientific Session & Expo being held in Washington, DC, from April 2 to 4, 2022. The team at Cardiology Advisor will be reporting on the latest news and research conducted by clinicians and scientists in the field. Check back for more from the ACC 2022 .
On a county level, reduced rates of hospital readmission for patients being treated for heart failure (HF) or myocardial infarction (MI), or who are receiving a coronary artery bypass graft (CABG), are associated with a larger proportion of female general cardiologists. These findings were presented at the American College of Cardiology 71st Annual Scientific Session & Expo, from April 2nd through 4th, in Washington, DC.
In the United States, a small percentage of practicing cardiologists are women. Researchers hoped to discover if a connection exists between the proportion of female cardiologists and hospital readmission rates for certain cardiovascular outcomes.
To accomplish this, researchers conducted a retrospective study utilizing billing provider and hospital readmission rate data from the Centers for Medicare and Medicaid Services for patients with history of HF, MI, and CABG. The predictor being studied, county by county, was the proportion of female general cardiologists. The primary outcome of the study was the ratio of hospitals’ readmissions to discharges.
A significant correlation was found between counties with larger proportions of female general cardiologists and hospital readmission for HF (P =.0036), readmission for MI (P =.033), and readmission for CABG (P =.008). Researchers also observed the combined readmission rates for HF, MI, and CABG were reduced (P =.015). Across hospitals, minimal variability in readmission rates was noted (Multiple R2=0.0121).
The researchers wrote, “At a county level, a higher proportion of female general cardiologists correlates with reduced rates of hospital readmissions for HF, MI, and CABG.” They noted that to understand the underlying factors leading to this correlation, further research would be required.
