PurposeThe burden of community-acquired pneumonia (CAP) is not well described in the US Veterans Health Administration (VHA).MethodsCAP was defined as having a pneumonia diagnosis with evidence of chest X-ray, and no evidence of prior (90 days) hospitalization/long-term care. We calculated incidence rates of adult CAP occurring in inpatient or outpatient VHA settings in 2011. We also estimated the proportion of VHA CAP patients who were hospitalized, were readmitted within 30 days of hospital discharge, and died (any cause) in the year following diagnosis. Incremental costs during the 90 days following a CAP diagnosis were estimated from the perspective of the VHA.ResultsIn 2011, 34,101 Veterans developed CAP (35,380 episodes) over 7,739,757 VHA person-years. Median age of CAP patients was 65 years (95 % male). CAP incidence rates were higher for those aged ≥50 years. A majority of Veterans aged 50–64 (53 %) and ≥65 (66 %) years had ≥1 chronic medical (moderate risk) or immunocompromising (high risk) condition. Compared to those at low-risk (healthy), moderate- and high-risk Veterans were >3 and >6 times more likely to develop CAP, respectively. The percentage of CAP patients who were hospitalized was 45 %, ranging from 12 % (age 18–49, low risk) to 57 % (age ≥65, high risk). One-year all-cause mortality rates ranged from 1 % (age 18–49, low risk) to 36 % (age ≥65, high risk). Annual VHA medical expenditure related to CAP was estimated to be $750 million (M) ($415M for those aged ≥65 years).ConclusionA focus on CAP prevention among older Veterans and those with comorbid or immunocompromising conditions is important.Electronic supplementary materialThe online version of this article (doi:10.1007/s15010-015-0789-3) contains supplementary material, which is available to authorized users.
