Hospitalizations Related to Afib Rise, But Mortality Rates Fall

FEBRUARY 03, 2017

US patients with atrial fibrillation (AF) are being hospitalized more frequently than in the past, but mortality rates are getting better, according to a study recently published in Circulation.

James Freeman, MD, an assistant professor of medicine at the Yale University School of Medicine in New Haven, Connecticut, and colleagues analyzed data collected between 1999 and 2013 on Medicare fee-for-service patients, aged 65 and older. 

During that time, hospitalizations rose by nearly 1% per year and costs per stay substantially increased, the researchers noted. They also noted declines in the 30-day readmission rate, as well as decreases in the 30-day and 1-year mortality rates. The researchers noted that access to more AF treatments over the study period may have contributed to less mortality rates, the researchers noted.

The study is supported by the National Heart, Lung, and Blood Institute.

The researchers reported obtaining research grants from Medtronic and from Johnson & Johnson, through Yale University, to develop methods of clinical trial data sharing, as well as working with a cardiac scientific advisory board for UnitedHealth. Another researcher reportedreceived support serving on an advisory board from Janssen Pharmaceuticals.
