Antibiotic and antifungal use in paediatric departments at three academic hospitals in South Africa

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.

Biomarker-guided duration of antibiotic treatment in children hospitalised with confirmed or suspected bacterial infection: statistical analysis plan for the BATCH trial and PRECISE sub-study

INTRODUCTION

The BATCH trial is a multi-centre randomised controlled trial to compare procalcitonin-guided management of severe bacterial infection in children with current management. PRECISE is a mechanistic sub-study embedded into the BATCH trial. This paper describes the statistical analysis plan for the BATCH trial and PRECISE sub-study.

METHODS

The BATCH trial will assess the effectiveness of an additional procalcitonin test in children (aged 72 h to 18 years) hospitalised with suspected or confirmed bacterial infection to guide antimicrobial prescribing decisions. Participants will be enrolled in the trial from randomisation until day 28 follow-up. The co-primary outcomes are duration of intravenous antibiotic use and a composite safety outcome. Target sample size is 1942 patients, based on detecting a 1-day reduction in intravenous antibiotic use (90% power, two-sided) and on a non-inferiority margin of 5% risk difference in the composite safety outcome (90% power, one-sided), while allowing for up to 10% loss to follow-up.

RESULTS

Baseline characteristics will be summarised overall, by trial arm, and by whether patients were recruited before or after the pause in recruitment due to the COVID-19 pandemic. In the primary analysis, duration of intravenous antibiotic use will be tested for superiority using Cox regression, and the composite safety outcome will be tested for non-inferiority using logistic regression. The intervention will be judged successful if it reduces the duration of intravenous antibiotic use without compromising safety. Secondary analyses will include sensitivity analyses, pre-specified subgroup analyses, and analysis of secondary outcomes. Two sub-studies, including PRECISE, involve additional pre-specified subgroup analyses. All analyses will be adjusted for the balancing factors used in the randomisation, namely centre and patient age.

CONCLUSION

We describe the statistical analysis plan for the BATCH trial and PRECISE sub-study, including definitions of clinical outcomes, reporting guidelines, statistical principles, and analysis methods. The trial uses a design with co-primary superiority and non-inferiority endpoints. The analysis plan has been written prior to the completion of follow-up.

To become an expert within a week: Children's and parents' experiences of the child being diagnosed with type 1 diabetes and receiving diabetes education - A qualitative interview study

PURPOSE

To explore children's and parents' experiences of the child being diagnosed with type 1 diabetes and receiving diabetes education during hospitalisation.

DESIGN AND METHODS

A qualitative interpretive design was applied. Semi-structured interviews with 15 children and their parent(s) were conducted. Data were analysed via thematic analysis.

RESULTS

The analysis revealed three themes: To be diagnosed with diabetes turns one's world upside down; It is positive to meet friendly and helpful healthcare professionals; and Diabetes education is overwhelming but required.

CONCLUSIONS

To be hospitalised and receive a diabetes diagnosis is overwhelming. The family must learn, in a short time, the basic skills to manage the condition. While learning, the child may fluctuate between being active and passive. In this vulnerable situation, it is positive to meet helpful healthcare professionals. Children find the motivation to learn, as they want to self-manage and be independent. All necessary education is given, but often the families would like to be more actively involved in the teaching. Sometimes, the teaching is also very compressed.

PRACTICE IMPLICATIONS

It is important to be aware of the vulnerable situation of the family and to adjust education to the fluctuations of the child. Teaching should be simplified and broken down stepwise, using pictures, artefacts, etc., to support the learning. More involvement may make education even more engaging and interesting. It has to be considered whether the education can be compressed into too short a time, making it difficult to transfer to the everyday lives of the families.

Discrepancies between nurses' current and perceived necessary practices of family-centred care for hospitalised children and their families: A cross-sectional study

PURPOSE

This study investigated (1) the discrepancies between the nurses' current and perceived necessary practices of family-centred care (FCC), and (2) the nurses' demographic characteristics associated with current and perceived necessary practices of FCC for hospitalised children and their families in Malawi.

DESIGN AND METHODS

A cross-sectional study involving 444 nurses was conducted. The Family-Centred Care Questionnaire-Revised was used to examine the discrepancies between the nurses' current and perceived necessary practices of FCC. Univariate and multivariate statistical analyses were performed to identify the nurses' demographic characteristics associated with current and perceived necessary practices of FCC.

RESULTS

The total mean score of the nurses' current practices of FCC (M = 34.78, SD = 7.06) was significantly lower than that of the nurses' practices of FCC that were perceived as necessary (M = 38.63, SD = 5.60, p < 0.001). The nurses who were over 40 years of age (regression coefficient, β = 9.162, p = 0.014), had a postgraduate qualification (β = 23.314, p < 0.001), were separated or widowed (β = 9.661, p = 0.029), had a Tumbuka cultural background (β = 12.984, p < 0.001), were Seventh-day Adventist members (β = 8.863, p = 0.026), and worked in mission hospitals (β = 16.401, p = 0.021) were more likely to implement current practices of FCC. Conversely, the nurses who were members of the Moslem, Buddhist, or Hindi religious denomination (β = 6.587, p = 0.040), had a Tonga or Ngonde cultural background (β = 6.625, p = 0.046), and were nurse midwife technicians (β = -23.528, p = 0.012) were more likely to implement practices of FCC that they perceived as necessary.

CONCLUSION

Significant differences between the nurses' current and perceived necessary practices of FCC suggested that there were barriers to implementing necessary practices of FCC. The nurses' cultural and religious backgrounds were predictors of current practices of FCC, and this finding could direct the future development and testing of FCC interventions in Malawi.

PRACTICE IMPLICATIONS

Continued educational activities and research on the factors that contributed to the discrepancies between the nurses' current and perceived necessary practices of FCC and their impact on FCC in Malawi are critical.

Health-Related Quality of Life of Nurses Caring for Hospitalised Children and Their Families: A National Cross-Sectional Study

PURPOSE

Health-related quality of life (HRQoL) continues to be understudied among nurses in developing countries. This study aimed to assess (1) the HRQoL of nurses in Malawi caring for hospitalised children and their families, and (2) the nurses' demographic characteristics associated with their HRQoL.

DESIGN AND METHODS

The cross-sectional study was carried out at 23 hospitals in Malawi, and 203 nurses participated, resulting in a 96% response rate. The Medical Outcomes Study 36-Item Short Form Health Survey was used to collect data. The physical and mental health component scores were evaluated and compared with those in a Cyprus study as the population norm. Both univariate and multivariate analyses were performed, with the significance level set at 0.05.

RESULTS

The nurses' HRQoL was moderately impaired; however, the mean scores of both the physical and the mental health components of the nurses in the Cyprus study were statistically lower than those of the Malawian nurses (t = 36.541, p < 0.001 and t = 19.477, p < 0.001, respectively). Age was independently associated with a better physical health status (β = 29.949, p = 0.038), while female nurses were more likely to report a negative physical health status compared with male nurses (β = -97.481, p = 0.002).

CONCLUSION

The findings suggested that the Malawian nurses were affected by work-related stress, which affected their mental and physical health status. The current findings represent preliminary data, and as such further studies on the association between work-related factors and HRQoL are needed.

PRACTICE IMPLICATIONS

Knowledge of HRQoL from the perspective of nurses can help healthcare organisations to develop interventions to limit the negative impacts of work-related stress on nurses caring for children.

Bacteria and viruses in the upper respiratory tract of Congolese children with radiologically confirmed pneumonia

BACKGROUND

Acute pneumonia remains a leading cause of death among children below 5 years of age in the Democratic Republic of the Congo (DR Congo), despite introduction of the 13-valent pneumococcal conjugate vaccine (PCV13) in 2013. Potential pathogens in the nasopharynx of hospitalised children with pneumonia have not been studied previously in DR Congo. Here we compare clinical characteristics, risk factors and nasopharyngeal occurrence of bacteria and viruses between children with severe and non-severe pneumonia.

METHODS

Between June 2015 and June 2017, 116 children aged from 2 to 59 months hospitalised due to radiologically confirmed pneumonia at Panzi referral university hospital, Bukavu, Eastern DR Congo were included in the study and sampled from nasopharynx. A multiplex real-time PCR assay for detection of 15 different viruses and 5 bacterial species was performed and another multiplex PCR assay was used for pneumococcal serotype/serogroup determination.

RESULTS

During the study period 85 (73%) of the children with radiologically confirmed pneumonia met the WHO classification criteria of severe pneumonia and 31 (27%) had non-severe pneumonia. The fatality rate was 9.5%. Almost all (87%) children were treated with antibiotics before they were hospitalised, in most cases with amoxicillin (58%) or trimethoprim-sulfamethoxazole (20%). The frequency of potential pathogens in the nasopharynx of the children was high, and any viral or bacterial nucleic acids present at high levels, irrespective of species or type, were significantly associated with severe pneumonia as compared with non-severe cases (52% versus 29%, p = 0.032). White blood cell count > 20,000/μL and C-Reactive Protein > 75 mg/dL were associated with severe pneumonia at admission. Fatal outcome was in the multivariable analysis associated with having a congenital disease as an underlying condition. One or more pneumococcal serotypes/serogroups could be identified in 61 patients, and out of all identified serotypes 31/83 (37%) were non-PCV13 serotypes.

CONCLUSIONS

The occurrence of any bacteria or any viruses at high levels was associated with severe pneumonia at admission. Children with congenital disorders might need a higher attention when having symptoms of acute respiratory infection, as developed pneumonia could lead to fatal outcome.

More training and awareness are needed to improve the recognition of undernutrition in hospitalised children

AIM

Reports suggest that 10% of hospitalised children in Europe are undernourished. We investigated whether nutritional screening tools (NST) were used in Belgian secondary-level hospitals, examined strategies for detecting undernutrition and identified barriers preventing the systematic management of undernutrition.

METHODS

A nationwide questionnaire-based survey of paediatric departments in Belgian secondary-level hospitals was carried out from September 2013 to February 2014. Respondents were dived into French-speaking (Walloon + Brussels) and Dutch-speaking (Flemish) departments.

RESULTS

We received replies from 71 of the 97 (73.2%) departments. Half of the departments - 39.5% Flemish speaking and 71.4% Walloon speaking - carried out nutritional screening. Undernutrition was identified by measuring weight and length or height (92.7% of cases), clinical appraisal (74.7%), mid-upper arm circumference and/or skin fold thickness (19.7%). There was no protocol for undernutrition in many Flemish (60.5%)- and Walloon (28.6%)-speaking departments. Reasons given for not screening were as follows: lack of training (46.9%), ignorance of NST (42.2%) and lack of time (29.7%).

CONCLUSION

Half of the paediatric departments in Belgian secondary-level hospitals did not carry out nutritional screening, and differences in current practices and attitudes may be due to cultural and/or educational differences.

A worrying trend in weight-adjusted paediatric antibiotic use in a Norwegian tertiary care hospital

AIM

The World Health Organization recommends the defined daily dose (DDD) as the standard unit of measurement for antibiotic use, but this is not applicable in children. We aimed to assess paediatric antibiotic use in a Norwegian tertiary care hospital using a novel weight-adjusted method.

METHODS

We obtained antibiotic purchase data from the hospital pharmacy and administrative data for all admissions from 2002 to 2009 to the paediatric wards at Oslo University Hospital, Rikshospitalet. Recommended daily doses per 100 kg days (RDDs/kg days) were calculated based on national guidelines for paediatric antibiotic use, length of stay and estimated weight for sex and age using national growth references.

RESULTS

Total antibiotic use increased significantly from 51.8 to 65.5 RDDs/100 kg days. We found statistically significant annual increases in the consumption of carbapenems (18.0%), third-generation cephalosporins (6.0%) and imidazole derivatives (6.6%) and a considerable difference between total antibiotic use measured in RDDs/100 kg days and DDDs/100 bed days for neonates.

CONCLUSION

Weight-adjusted antibiotic use provided a more meaningful description of the quantities of antibiotics consumed than DDDs/100 bed days, particularly for neonates. Total antibiotic use, use of meropenem, third-generation cephalosporins and imidazole derivatives increased significantly despite low prevalence of antibiotic-resistant pathogens.
