Optimizing Antibiotic Treatment of Skin Infections in Pediatric Emergency and Urgent Care Centers

A National Quality Improvement Collaborative to Improve Antibiotic Use in Pediatric Infections

BACKGROUND

Nearly 25% of antibiotics prescribed to children are inappropriate or unnecessary, subjecting patients to avoidable adverse medication effects and cost.

METHODS

We conducted a quality improvement initiative across 118 hospitals participating in the American Academy of Pediatrics Value in Inpatient Pediatrics Network 2020 to 2022. We aimed to increase the proportion of children receiving appropriate: (1) empirical, (2) definitive, and (3) duration of antibiotic therapy for community-acquired pneumonia, skin and soft tissue infections, and urinary tract infections to ≥85% by Jan 1, 2022. Sites reviewed encounters of children >60 days old evaluated in the emergency department or hospital. Interventions included monthly audit with feedback, educational webinars, peer coaching, order sets, and a mobile app containing site-specific, antibiogram-based treatment recommendations. Sites submitted 18 months of baseline, 2-months washout, and 10 months intervention data. We performed interrupted time series (analyses for each measure.

RESULTS

Sites reviewed 43 916 encounters (30 799 preintervention, 13 117 post). Overall median [interquartile range] adherence to empirical, definitive, and duration of antibiotic therapy was 67% [65% to 70%]; 74% [72% to 75%] and 61% [58% to 65%], respectively at baseline and was 72% [71% to 72%]; 79% [79% to 80%] and 71% [69% to 73%], respectively, during the intervention period. Interrupted time series revealed a 13% (95% confidence interval: 1% to 26%) intercept change at intervention for empirical therapy and a 1.1% (95% confidence interval: 0.4% to 1.9%) monthly increase in adherence per month for antibiotic duration above baseline rates. Balancing measures of care escalation and revisit or readmission did not increase.

CONCLUSIONS

This multisite collaborative increased appropriate antibiotic use for community-acquired pneumonia, skin and soft tissue infections, and urinary tract infection among diverse hospitals.

Reducing Antibiotic Duration for Uncomplicated UTI in the Pediatric Emergency Department

BACKGROUND

Short-duration (3-5 days) antibiotic treatment of uncomplicated urinary tract infection (uUTI) in children >24 months of age is equivalent to longer-duration antibiotic treatment, with added benefits of antibiotic stewardship. At our pediatric emergency department (ED), 13% of 5- to 18-year-old patients discharged with uUTI received ≤5 days of antibiotics. We aimed to increase short-duration prescriptions in patients with uUTI from 13% to >50% over 12 months.

METHODS

This quality improvement project was conducted from January 2021 to August 2022. Complicated UTI was excluded. Interventions included education, practice feedback, and electronic health record changes. The outcome measure, the proportion of children treated with a short antibiotic duration, was studied by using p-charts. Antibiotic days saved were calculated. Revisits with UTI within 14 days of confirmed uUTI treated with short-duration antibiotics (balancing measure) were analyzed by using Fisher's exact test.

RESULTS

In 1292 (n = 363 baseline, 929 post-intervention) eligible patients treated for uUTI, shorter antibiotic duration increased from 13% to 91%. We met our 50% aim within 2 months, with continued improvement leading to an additional centerline shift. Consequently, 2619 antibiotic days were saved. Two of 334 (0.6%) patients returned (P = NS) within 14 days of the index visit with a culture-positive uUTI.

CONCLUSIONS

By using education, feedback, and electronic health record changes, we decreased antibiotic duration in children discharged from the ED for uUTI without a significant increase in return visits with UTI. These interventions can be expanded to wider age groups and other outpatient settings.

Antimicrobial Management of Skin and Soft Tissue Infections among Surgical Wards in South Africa: Findings and Implications

Skin and soft tissue infections (SSTIs) are one of the most common infectious diseases requiring antibiotics. However, complications of SSTIs may lead to the overprescribing of antibiotics and to subsequent antibiotic resistance. Consequently, monitoring the prescribing alignment with the current recommendations from the South African Standard Treatment Guidelines (STG) is necessary in order to improve future care. This study involved reviewing pertinent patients with SSTIs who were prescribed antimicrobials in the surgical ward of a leading South African tertiary public hospital from April to June 2021 using an adapted data collection tool. Sixty-seven patient files were reviewed. Among the patients with SSTIs, hypertension and chronic osteomyelitis were the most frequent co-morbidities at 22.4% and 13.4%, respectively. The most diagnosed SSTIs were surgical site infections (35.1%), wound site infections (23%), and major abscesses (16.2%). Blood cultures were performed on 40.3% of patients, with Staphylococcus aureus (32.7%) and Enterococcus spp. (21.2%) being the most cultured pathogens. Cefazolin was prescribed empirically for 46.3% of patients for their SSTIs. In addition, SSTIs were treated with gentamycin, ciprofloxacin, and rifampicin at 17.5%, 11.3%, and 8.8%, respectively, with treatment fully complying with STG recommendations in 55.2% of cases. Overall, the most common cause of SSTIs was Staphylococcus aureus, and empiric treatment is recommended as the initial management. Subsequently, culture sensitivities should be performed to enhance adherence to STGs and to improve future care.
