Things We Do For No Reason: Routine Blood Culture Acquisition for Children Hospitalized with Community-Acquired Pneumonia

• Do not obtain blood culture routinely for children aged >3 months hospitalized for uncomplicated CAP.
• Obtain a blood culture for the following hospitalized patients with CAP:

a. Patients with complicated CAP as defined by the IDSA, particularly those with empyema, abscess, or fistula, or metastatic complications of pneumonia (Table); or

b. Patients with CAP requiring ICU care²⁰ for the management of shock and/or advanced respiratory support.

c. Patients with CAP judged to need antibiotic treatment with an agent other than the IDSA-recommended ampicillin/penicillin (concern for pathogens other than penicillin-sensitive S. pneumonia, immunocompromised or under-immunized status, or inadequate clinical response to empiric ampicillin therapy).

Implementing a more targeted approach to blood culture acquisition for hospitalized children with CAP will hopefully increase the yield of true bacterial pathogens that alter management decisions. A targeted approach for the child in the opening vignette would have saved him from the pain of unnecessary phlebotomy (repeat culture), exposure to vancomycin as a nephrotoxic agent, and an additional hospital day.
