Abstract 29: Cardiac Surgery Episode Expenditures Associated With Healthcare-Associated Pneumonia (original) (raw)

Circulation: Cardiovascular Quality and Outcomes, 2018

Abstract

Objective: Pneumonia is the most common healthcare-associated infection (HAI) in patients undergoing cardiac surgery. While current efforts have focused on risk factors and clinical implications of pneumonia, few have examined its overall financial impact. Our objective was to compare 90-day episode expenditures for Medicare patients undergoing coronary artery bypass graft surgery (CABG) with and without pneumonia. Methods and Results: Using 2014-2015 Medicare Part A and B administrative claims data, we identified 50,550 patients undergoing isolated CABG. From this sample, we applied an established claims-based algorithm to identify 3,224 (6.4%) patients with new onset of pneumonia during their index admission and after their surgical procedure. Using generalized linear models, we found that average 90-day episode expenditures were 30% higher in patients with pneumonia ($55,442 vs. $42,745, p<0.001), adjusting for patient factors (age, sex, race, dual eligible status, and Elixhau...
