BACKGROUND - National guidelines for the management of community-acquired pneumonia (CAP) in children were published in 2011. These guidelines discourage most diagnostic testing for outpatients, as well as repeat testing for hospitalized patients who are improving. We sought to evaluate the temporal trends in diagnostic testing associated with guideline implementation among children with CAP.

METHODS - Children 1 to 18 years old who were discharged with pneumonia after emergency department (ED) evaluation or hospitalization from January 1, 2008 to June 30, 2014 at any of 32 children's hospitals participating in the Pediatric Health Information System were included. We excluded children with complex chronic conditions and those requiring intensive care or who underwent early pleural drainage. We compared use of diagnostic testing (blood culture, complete blood count [CBC], C-reactive protein [CRP], and chest radiography [CXR]) before and after release of the guidelines, and assessed for temporal trends using interrupted time series analysis. We also calculated the cost impact of these changes on diagnostic utilization and evaluated the variability of the guideline's impact across hospitals.

RESULTS - Overall, 220,539 patients were included; 53% were male and the median age was 4 years (interquartile range, 2-7). For patients discharged from the ED with CAP, diagnostic utilization rates for blood culture, CBC, CRP, and CXR were higher after guideline publication compared with expected utilization rates without guidelines. In contrast, initial testing and repeat testing among patients hospitalized with CAP was lower after guideline publication. There were modest reductions in estimated costs associated with these changes. However, wide variability was observed in the impact of the guidelines across hospitals.

CONCLUSIONS - Publication of national pneumonia guidelines in 2011 was associated with modest changes in diagnostic testing for children with CAP. However, the changes varied across hospitals, and the financial impact was modest. Local implementation efforts are warranted to ensure widespread guideline adherence.
