- Abstract
Background Few studies have quantified the risk of community-acquired pneumonia (CAP) among adults with co-morbidities. Combining data from the population-based, prospective Etiology of Pneumonia in the Community study (EPIC) and the nationwide health-related Behavioral Risk Factor Surveillance System (BRFSS) telephone-survey, we estimated the annual risk of hospitalization for CAP among adults with co-morbidities. Methods We identified adults hospitalized with radiographic and clinical CAP at hospitals in Chicago, IL and Nashville, TN from July 2010 to June 2012. Using 2011 BRFSS data, we estimated the prevalence of the population with selected co-morbidities (chronic lung disease [CLD], cardiovascular disease [CVD], chronic kidney disease [CKD], or diabetes) in the EPIC study catchment counties, as well as the population without co-morbidities. We estimated the incidence of hospitalized CAP, age-adjusted relative risk (RR) using Poisson regression, and population attributable fraction for each co-morbidity. Results Among 2,061 adult patients enrolled in EPIC, 1,428 (69%) had at least one selected co-morbidity, most commonly CLD (42%) and CVD (35%). Among the adult population in the EPIC catchment area, 17% had ≥1 selected co-morbidity. The overall incidence of hospitalized CAP was 24.8/10,000, 118.7/10,000 among adults with ≥1 co-morbidity, and 11.2/10,000 among adults without a co-morbidity. Compared with patients without co-morbidities, the incidence of hospitalization for CAP was higher among patients with CLD (aRR: 20.7 [95% confidence interval [CI]: 20.0–21.5]), CKD (aRR: 14.5 [CI: 13.8–15.1]), CVD (aRR: 14.0 [CI: 13.5–14.6]), and diabetes (aRR: 6.2 [CI: 5.9–6.4]). While CLD and CVD accounted for high proportions of the incidence of CAP hospitalizations in the study population, the contribution of the selected co-morbidities varied by age groups (figure). Conclusion There is an increased risk of hospitalization for CAP among adults with co-morbidities, particularly chronic lung and cardiovascular disease. As a large portion of CAP is attributable to these co-morbidities, targeted public health interventions, such as vaccination and risk communication, need to be reinforced among these high-risk groups.
