RESUMO
BACKGROUND: Hospitalised neonates are vulnerable to infection and have high rates of antibiotic utilisation. METHODS: Fourteen South African neonatal units (seven public, seven private sector) assembled multidisciplinary teams involving neonatologists, microbiologists, pharmacists, and nurses to implement prospective audit and feedback neonatal antimicrobial stewardship (NeoAMS) interventions. The teams attended seven online training sessions. Pharmacists conducted weekday antibiotic prescription reviews in the neonatal intensive care unit and/or neonatal wards providing feedback to the clinical teams. Anonymised demographic and NeoAMS interventions data were aggregated for descriptive purposes and statistical analysis. FINDINGS: During the 20-week NeoAMS intervention in 2022, 565 neonates were enrolled. Pharmacists evaluated seven hundred antibiotic prescription episodes; rule-out sepsis (180; 26%) and culture-negative sepsis (138; 20%) were the most frequent indications for antibiotic prescription. For infection episodes with an identified pathogen, only 51% (116/229) of empiric treatments provided adequate antimicrobial coverage. Pharmacists recommended 437 NeoAMS interventions (0·6 per antibiotic prescription episode), with antibiotic discontinuation (42%), therapeutic drug monitoring (17%), and dosing (15%) recommendations most frequent. Neonatal clinicians' acceptance rates for AMS recommendations were high (338; 77%). Mean antibiotic length of therapy decreased by 24% from 9·1 to 6·9 days (0·1 day decrease per intervention week; p=0·001), with the greatest decline in length of therapy for culture-negative sepsis (8·2 days (95%CI 5·7-11·7) to 5·9 days (95% CI 4·6-7·5); p=0·032). INTERPRETATION: This neonatal AMS programme was successfully implemented in heterogenous and resource-limited settings. Pharmacist-recommended AMS interventions had high rates of clinician acceptance. The NeoAMS intervention significantly reduced neonatal antibiotic use, particularly for culture-negative sepsis. FUNDING: A grant from Merck provided partial support.
RESUMO
INTRODUCTION: Pharmacists in low-middle-income countries (LMIC) are few and lack antibiotic stewardship (AS) training. The ability was assessed of non-specialised pharmacists to implement stewardship interventions and improve adherence to the South African community-acquired pneumonia (CAP) guideline in public and private hospitals. METHODS: This was a multicentre, prospective cohort study of adult CAP patients hospitalised between July 2017 and July 2018. A CAP bundle was developed of seven process measures (diagnostic and AS) that pharmacists used to audit compliance and provide feedback. CAP bundle compliance rates and change in outcome measures [mortality, length of stay (LOS) and infection-related (IR)-LOS] during pre- and post-implementation periods were compared. RESULTS: In total, 2464 patients in 39 hospitals were included in the final analysis. Post-implementation, overall CAP bundle compliance improved from 47·8% to 53·6% (confidence interval [CI] 4·1-7·5, p<0·0001), diagnostic stewardship compliance improved from 49·1% to 54·6% (CI 3·3-7·7, p<0·0001) and compliance with AS process measures from 45·3% to 51·6% (CI 4·0-8·6, p<0·0001). Improved compliance with process measures was significant for five (2 diagnostic, 3 AS) of seven components: radiology, laboratory, antibiotic choice, duration and intravenous to oral switch. There was no difference in mortality between the two phases, [4·4%(55/1247) vs. 3·9%(47/1217); p=0·54], median LOS or IR LOS 6·0 vs. 6·0 days (p=0·20) and 5·0 vs. 5·0 days (p=0·40). CONCLUSION: Non-specialised pharmacists in public and private hospitals implemented stewardship interventions and improved compliance to SA CAP guidelines. The methodology of upskilling and a shared learning stewardship model may benefit LMIC countries.
