Neonatal Antifungal Consumption Is Dominated by Prophylactic Use; Outcomes From The Pediatric Antifungal Stewardship: Optimizing Antifungal Prescription Study.
BACKGROUND: Diagnostic challenges combined with the vulnerability of neonates to develop invasive candidiasis (IC) may lead to antifungal administration in the absence of IC. A modified point-prevalence study was performed to obtain an improved insight and understanding of antifungal prescribing in this specific patient population. METHODS: Neonates and infants ≤90 days of age receiving systemic antifungals from 12 centers in England were included. Data were collected prospectively during 26 consecutive weeks and entered into an online REDCap database. RESULTS: Two hundred eighty neonates and infants were included, the majority ≤1 month of age (68.2%). Prematurity was the commonest underlying condition (68.9%). Antifungals were prescribed for prophylactic reason in 79.6%; of those, 64.6% and 76.3% were extreme low birth weight infants and prematurely born neonates, respectively. Additional risk factors were present in almost all patients, but only 44.7% had ≥3 risk factors rendering them more susceptible to develop IC. Nonpremature and non extremely low birth weight premature infants only scored ≥3 risk factors in 32.6% and 15%, respectively. Fluconazole was the most common antifungal used (76.7% of all prescriptions), and commonly underdosed as treatment. The number of microbiological proven IC was low, 5.4%. CONCLUSIONS: Neonatal antifungal prophylaxis is commonly prescribed outside the recommendations based on known risk profiles. Fluconazole is the main antifungal prescribed in neonates and infants, with underdosing frequently observed when prescribed for treatment. Number of proven IC was very low. These observations should be taken into consideration to develop a national pediatric Antifungal Stewardship program aiming to guide rational prescribing
Comparison of diagnoses of early onset sepsis associated with use of Sepsis Risk Calculator versus NICE CG149: a prospective, population-wide cohort study in London, UK, 2020-21
Objective: We sought to compare the incidence of early-onset sepsis (EOS) in infants ≥34 weeks’ gestation identified > 24 hours after birth, in hospitals using the Kaiser Permanente sepsis risk calculator (SRC) with hospitals using the NICE guidance. Design and setting: Prospective observational population-wide cohort study involving all 26 hospitals with neonatal units co-located with maternity services across London (10 using SRC, 16 using NICE). Participants: All livebirths ≥34 weeks’ gestation between September 2020 and August 2021. Outcome measures: EOS was defined as isolation of a bacterial pathogen in the blood or CSF culture from birth to 7 days of age. We evaluated the incidence of EOS identified by culture obtained >24 hours to 7 days after birth. We also evaluated the rate empiric antibiotics were commenced >24 hours to 7 days after birth, for a duration of ≥5 days, with negative blood or CSF cultures. Results: Of 99,683 livebirths, 42,952 (43%) were born in SRC hospitals and 56,731 (57%) in NICE hospitals. The overall incidence of EOS (24 hours was 2.3/100,000 (n=1) for SRC versus 7.1/100,000 (n=4) for NICE (odds ratio 0·5, 95%CI [0·1; 2·7]). This corresponded to (1/20) 5% (SRC) versus (4/45) 8.9% (NICE) of EOS cases (chi=0.3, p=0.59). Empiric antibiotics were commenced >24 hours to 7 days after birth in 4·4/1000 (n=187) for SRC versus 2·9/1000 (n=158) for NICE (odds ratio 1·5, 95%CI [1·2; 1·9]). 3111 (7%) infants received antibiotics in the first 24 hours in SRC hospitals versus 8428 (15%) in NICE hospitals. Conclusion: There was no significant difference in the incidence of EOS identified >24 hours after birth between SRC and NICE hospitals. SRC use was associated with 50% fewer infants receiving antibiotics in the first 24 hours of life
