Short- Versus Prolonged-Duration Antibiotics for Outpatient Pneumonia in Children

Improving Short Course Treatment of Pediatric Infections: A Randomized Quality Improvement Trial

BACKGROUND AND OBJECTIVES

Short courses of antibiotic treatment are effective for pediatric community-acquired pneumonia (CAP) and skin and soft tissue infections (SSTI). We compared the effectiveness of education with performance feedback, clinical decision support (CDS), and the combination in encouraging appropriately short treatment courses by primary care clinicians.

METHODS

We designed a site-randomized, quality improvement trial within a large pediatric primary care network. Each practice was randomly assigned to 1 of 4 groups: education and feedback; CDS; both interventions ("combined group"); and control. We performed difference-in-differences analysis to compare the proportion of cases with short course treatment before and after intervention among the 4 groups.

RESULTS

For all cases of CAP and SSTI, the proportion in the control group treated with the recommended duration did not change from the baseline period (26.1% [679 of 2603]) to the intervention period (25.8% [196 of 761]; P = .9). For the education and feedback group, the proportion rose from 22.3% (428 of 1925) to 45.0% (239 of 532; P < .001); for the CDS group, from 26.6% (485 of 1824) to 52.3% (228 of 436; P < .001); and for the combined group, from 26.2% (491 of 1875) to 67.8% (314 of 463; P < .001). A difference-in-differences analysis showed that all 3 intervention groups improved performance compared with the control group (P < .001); the combined group had greater improvement than the education and feedback group or the CDS group (P < .001).

CONCLUSIONS

In this quality improvement project to encourage shorter duration treatment of CAP and SSTI, both education with performance feedback and CDS were effective in modifying clinician behavior; however, the combination of the two was substantially more effective than either strategy alone.

Evaluation of a Pediatric Community-Acquired Pneumonia Antimicrobial Stewardship Intervention at an Academic Medical Center

(1) Background: Pneumonia is the leading diagnosis associated with antibiotic use in hospitalized children. The Infectious Diseases Society of America published pediatric community-acquired pneumonia (CAP) guidelines in 2011, but adherence to recommendations varies across institutions. The purpose of this study was to evaluate the impact of an antimicrobial stewardship intervention on antibiotic prescribing in pediatric patients admitted to an academic medical center. (2) Methods: This single-center pre/post-intervention evaluation included children admitted for CAP during three time periods (pre-intervention and post-intervention groups 1 and 2). The primary outcomes were changes in inpatient antibiotic selection and duration following the interventions. Secondary outcomes included discharge antibiotic regimens, length of stay, and 30-day readmission rates. (3) Results: A total of 540 patients were included in this study. Most patients were under five years of age (69%). Antibiotic selection significantly improved, with prescriptions for ceftriaxone decreasing (p < 0.001) and ampicillin increasing (p < 0.001) following the interventions. Antibiotic duration decreased from a median of ten days in the pre-intervention group and post-intervention group 1 to eight days in post-intervention group 2. (4) Conclusions: Our antibiotic stewardship intervention directed at pediatric CAP treatment resulted in improved antibiotic prescriptions and provides data that can be used to further educate providers at our institution.

Defining effective durations of antibiotic therapy for community-acquired pneumonia and urinary tract infections in hospitalized children

PURPOSE OF REVIEW

Community-acquired pneumonia (CAP) and urinary tract infections (UTI) are two common childhood infections often leading to hospital admission. National guidelines for CAP and UTI in children recommend durations of antibiotic therapy of 10 days and 7-14 days, respectively. Due to concerns of rising antimicrobial resistance and an increased awareness of harms associated with prolonged courses of antibiotics, there is a renewed emphasis on reevaluating commonly prescribed durations of antibiotic therapy across bacterial infections. We describe recent clinical trials and observational studies evaluating durations of therapy for CAP and UTI in adults and children and translate the findings to our suggested approach for selecting durations of antibiotic therapy in hospitalized children.

RECENT FINDINGS

There is a growing body of evidence, primarily in adults, that shorter durations of therapy than are commonly prescribed are just as effective as longer durations for CAP and UTIs.

SUMMARY

Combining clinical trial data from adults with available data in children, we believe it is reasonable to consider 5 days of therapy for CAP, 3-5 days of therapy for cystitis, and 7 days of therapy for pyelonephritis for most hospitalized children with uncomplicated infections.
