Objectives: South Africa implemented a National Strategic Framework to optimise antimicrobial stewardship in 2014; however, there is limited data on how this has affected prescribing, especially to children treated in academic centres. Methods: We conducted a point prevalence survey using the World Health Organization (WHO) methodology to evaluate antibiotic and antifungal prescribing practices in paediatric departments at three academic hospitals in South Africa. Results: We recorded 1946 antimicrobial prescriptions in 1191 children, with 55.2% and 39.2% of the antibiotics classified as WHO AWaRe Access and Watch drugs, respectively. There were significant differences in prescription of Reserve antibiotics and antifungals between institutions. Receipt of WHO Watch and Reserve antibiotics was independently associated with infancy (<12 months) and adolescents (13-17 years) (adjusted relative risk [aRR]: 2.09-9.95); prolonged hospitalisation (aRR: 3.29-30.08); rapidly or ultimately fatal illness (aRR: 1.94 to 5.52); and blood transfusion (aRR: 3.28-5.70). Antifungal prescribing was associated with treatment of hospital-associated infection (aRR: 2.90), medical prophylaxis (aRR: 3.30), and treatment in intensive care units (aRR: 2.15-2.27). Conclusions: Guidance on optimisation of infection prevention and control practice and strengthening of antimicrobial stewardship would impact positively on the care of sick children in our setting.
RESUMO
BACKGROUND: Self-monitoring of glucose is an essential component of type 1 diabetes (T1D) management. In recent years, continuous glucose monitoring (CGM) has provided an alternative to daily fingerstick testing for the optimisation of insulin dosing and general glucose management in people with T1D. While studies have been conducted to evaluate the impact of CGM on clinical outcomes in the US, Europe and Australia, there are limited data available for low- and middle-income countries (LMICs) and further empirical evidence is needed to inform policy decision around their use in these countries. METHODS: This trial was designed as a pragmatic, parallel-group, open-label, multicentre, three-arm, randomised (1:1:1) controlled trial of continuous or periodic CGM device use versus standard of care in people with T1D in South Africa and Kenya. The primary objective of this trial will be to assess the impact of continuous or periodic CGM device use on glycaemic control as measured by change from baseline glycosylated haemoglobin (HbA1c). Additional assessments will include clinical outcomes (glucose variation, time in/below/above range), safety (adverse events, hospitalisations), quality of life (EQ-5D, T1D distress score, Glucose Monitoring Satisfaction Survey for T1D), and health economic measures (incremental cost-effectiveness ratios, quality adjusted life years). DISCUSSION: This trial aims to address the substantial evidence gap on the impact of CGM device use on clinical outcomes in LMICs, specifically South Africa and Kenya. The trial results will provide evidence to inform policy and treatment decisions in these countries. TRIAL REGISTRATION: NCT05944731 (Kenya), July 6, 2023; NCT05944718 (South Africa), July 13, 2023.

BACKGROUND: The prevalence of antimicrobial prescriptions for healthcare-associated infections (HAI) in South Africa is largely unknown. This study aimed to estimate the point prevalence of pediatric antibiotic and antifungal usage in 3 South African academic hospitals. METHODS: This cross-sectional study included hospitalized neonates and children (0-15 years). We used the World Health Organization methodology for antimicrobial point prevalence studies, with weekly surveys to achieve a sample size of ~400 at each site. RESULTS: Overall, 1,946 antimicrobials were prescribed to 1,191 patients. At least 1 antimicrobial was prescribed for 22.9% [95% confidence interval (CI): 15.5-32.5%] of patients. The prevalence of antimicrobial prescribing for HAI was 45.6%. In the multivariable analysis, relative to children 6-12 years, neonates [adjusted relative risk (aRR): 1.64; 95% CI: 1.06-2.53], infants (aRR: 1.57; 95% CI: 1.12-2.21) and adolescents (aRR: 2.18; 95% CI: 1.45-3.29) had significantly increased risk of prescriptions for HAI. Being preterm (aRR: 1.33; 95% CI: 1.04-1.70) and underweight (aRR: 1.25; 95% CI: 1.01-1.54) was predictive of antimicrobial usage for HAI. Having an indwelling device, surgery since admission, blood transfusions and classification as rapidly fatal on McCabe score also increased the risk of prescriptions for HAI. CONCLUSIONS: The high prevalence of antimicrobial prescribing for HAI to treat children with recognized risk factors in academic hospitals in South Africa is concerning. Concerted efforts need to be made to strengthen hospital-level infection prevention and control measures, with a critical review of antimicrobial usage through functional antibiotic stewardship programs to preserve the available antimicrobial armamentarium at the hospital level.

Background. Serious infections in children are difficult to determine from symptoms and signs alone. Fever is both a marker of insignificant viral infection; as well as more serious bacterial sepsis. Therefore; seeking markers of invasive disease; as well as culture positivity for organisms; has been a goal of paediatricians for many years. In addition; the avoidance of unnecessary antibiotics is important in this time of emerging multiresistant micro-organisms. Objective. To ascertain whether acute-phase reactant tests predict positive culture results.Methods. A prospective; cross-sectional study over a 1-year period included all documented febrile childre nunder the age of 5 years (with an axillary temperature =38oC) who presented to Steve Biko Academic Hospital; Pretoria; with signs and symptoms of pneumonia; meningitis and/or generalised sepsis. Every child had clinical signs; chest radiograph findings; urine culture; blood testing (full blood count; C-reactive protein; procalcitonin) and blood culture results recorded. Results. A total of 63 patients were enrolled; all of whom had an axillary temperature =38oC. C-reactive protein; procalcitonin and white cell count did not predict the presence of positive blood culture or cerebrospinal fluid culture results; nor infiltrates on chest radiographs. No statistically significant correlations were found between the duration of hospital stay and the degree of fever (p=0.123); white cell count (p=0.611); C-reactive protein (p=0.863) or procalcitonin (p=0.392). Conclusion. Biomarkers do not seem to predict severity of infection; source of infection; or duration of hospitalisation in children presenting to hospital with fever. The sample size is however too small to definitively confirm this viewpoint. This study suggests that clinical suspicion of serious infection and appropriate action are as valuable as extensive testing
