Procalcitonin Use: Variation Across Hospitals and Trends Over Time

Management of Pediatric Pneumonia: A Decade After the Pediatric Infectious Diseases Society and Infectious Diseases Society of America Guideline

BACKGROUND

Incomplete uptake of guidelines can lead to nonstandardized care, increased expenditures, and adverse clinical outcomes. The objective of this study was to evaluate the impact of the 2011 Pediatric Infectious Diseases Society and Infectious Diseases Society of America (PIDS/IDSA) pediatric community-acquired pneumonia (CAP) guideline that emphasized aminopenicillin use and de-emphasized the use of chest radiographs (CXRs) in certain populations.

METHODS

This quasi-experimental study queried a national administrative database of children's hospitals to identify children aged 3 months-18 years with CAP who visited 1 of 28 participating hospitals from 2009 to 2021. PIDS/IDSA pediatric CAP guideline recommendations regarding antibiotic therapy, diagnostic testing, and imaging were evaluated. Segmented regression interrupted time series was used to measure guideline-concordant practices with interruptions for guideline publication and the Coronavirus Disease 2019 (COVID-19) pandemic.

RESULTS

Of 315 384 children with CAP, 71 804 (22.8%) were hospitalized. Among hospitalized children, there was a decrease in blood culture performance (0.5% per quarter) and increase in aminopenicillin prescribing (1.1% per quarter). Among children discharged from the emergency department (ED), there was an increase in aminopenicillin prescription (0.45% per quarter), whereas the rate of obtaining CXRs declined (0.12% per quarter). However, use of CXRs rebounded during the COVID-19 pandemic (increase of 1.56% per quarter). Hospital length of stay, ED revisit rates, and hospital readmission rates remained stable.

CONCLUSIONS

Guideline publication was associated with an increase of aminopenicillin prescribing. However, rates of diagnostic testing did not materially change, suggesting the need to consider implementation strategies to meaningfully change clinical practice for children with CAP.

Variation in bacterial pneumonia diagnoses and outcomes among children hospitalized with lower respiratory tract infections

BACKGROUND

Current diagnostics do not permit reliable differentiation of bacterial from viral causes of lower respiratory tract infection (LRTI), which may lead to over-treatment with antibiotics for possible bacterial community-acquired pneumonia (CAP).

OBJECTIVES

We sought to describe variation in the diagnosis and treatment of bacterial CAP among children hospitalized with LRTIs and determine the association between CAP diagnosis and outcomes.

DESIGN, SETTING AND PARTICIPANTS

This multicenter cross-sectional study included children hospitalized between 2017 and 2019 with LRTIs at 42 children's hospitals.

MAIN OUTCOME AND METHODS

We calculated the proportion of children with LRTIs who were diagnosed with and treated for bacterial CAP. After adjusting for confounders, hospitals were grouped into high, moderate, and low CAP diagnosis groups. Multivariable regression was used to examine the association between high and low CAP diagnosis groups and outcomes.

RESULTS

We identified 66,581 patients hospitalized with LRTIs and observed substantial variation across hospitals in the proportion diagnosed with and treated for bacterial CAP (median 27%, range 12%-42%). Compared with low CAP diagnosing hospitals, high diagnosing hospitals had higher rates of CAP-related revisits (0.6% [95% confidence interval: 0.5, 0.7] vs. 0.4% [0.4, 0.5], p = .04), chest radiographs (58% [53, 62] vs. 46% [41, 51], p = .02), and blood tests (43% [33, 53] vs. 26% [19, 35], p = .046). There were no significant differences in length of stay, all-cause revisits or readmissions, CAP-related readmissions, or costs.

CONCLUSION

There was wide variation across hospitals in the proportion of children with LRTIs who were treated for bacterial CAP. The lack of meaningful differences in clinical outcomes among hospitals suggests that some institutions may over-diagnose and overtreat bacterial CAP.
