eLearning significantly improves maternity professionals' knowledge of the congenital cytomegalovirus prevention guidelines.

AIMS: Cytomegalovirus (CMV) is a preventable cause of neurodevelopmental disability. Australian guidelines recommend that pregnant women are informed about CMV to reduce their risk of infection; however, less than 10% of maternity health professionals routinely provide prevention advice. The aim was to develop and evaluate the effectiveness of an eLearning course for midwives to improve knowledge and confidence about CMV. MATERIALS AND METHODS: Participants undertaking the course between March and November 2020 were invited to complete an evaluation questionnaire: before the course (T1), immediately after (T2) and three months post completion (T3). A linear mixed model was used to evaluate change in participant scores; P < 0.05 was considered statistically significant. RESULTS: Midwives (316/363, 87%), midwifery students (29/363, 8%) and nurses (18/363, 5%) participated. At T1 80% indicated they had not received education about CMV. Total adjusted mean scores for questionnaires completed between T1 (n = 363) and T2 (n = 238) increased significantly (from 17.2 to 22.8, P < 0.001). Limited available T3 scores (n = 27) (-1.7, P < 0.001), while lower than T2, remained higher than at T1 (+3.6, P < 0.001). Participants' awareness of CMV information resources improved from 10 to 97% from T1 to T2. Confidence in providing CMV advice increased from 6 to 95% between T1 and T2 (P < 0.001) and was maintained at T3. Almost all (99%) participants indicated they would recommend the course to colleagues. CONCLUSION: Participants who completed the eLearning course had significantly improved knowledge and confidence in providing advice about CMV. Programs targeting other maternity health professionals should be considered, to further support the implementation of the congenital CMV prevention guidelines.

Review of guidelines and recommendations from 17 countries highlights the challenges that clinicians face caring for neonates born to mothers with COVID-19.

AIM: This review examined how applicable national and regional clinical practice guidelines and recommendations for managing neonates born to mothers with COVID-19 mothers were to the evolving pandemic. METHODS: A systematic search and review identified 20 guidelines and recommendations that had been published by May 25, 2020. We analysed documents from 17 countries: Australia, Brazil, Canada, China, France, India, Italy, Japan, Saudi Arabia, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, the UK and the United States. RESULTS: The documents were based on expert consensus with limited evidence and were of variable, low methodological rigour. Most did not provide recommendations for delivery methods or managing symptomatic infants. None provided recommendations for post-discharge assimilation of potentially infected infants into the community. The majority encouraged keeping mothers and infants together, subject to infection control measures, but one-third recommended separation. Although breastfeeding or using breastmilk was widely encouraged, two countries specifically prohibited this. CONCLUSION: The guidelines and recommendations for managing infants affected by COVID-19 were of low, variable quality and may be unsustainable. It is important that transmission risks are not increased when new information is incorporated into clinical recommendations. Practice guidelines should emphasise the extent of uncertainty and clearly define gaps in the evidence.

Adherence to surgical antibiotic prophylaxis guidelines in children: A cohort study.

AIMS: Surgical antimicrobial prophylaxis (SAP) is an important measure to reduce post-operative infections. Guidelines exist, but their efficacy and performance in children is poorly understood compared with adults. To review adherence to SAP guidelines, this study assesses risk factors for non-adherence and rate of early post-surgical infections. METHODS: A retrospective cohort study of paediatric surgical cases (0-<18 years) at a tertiary children's hospital was performed. Patient characteristics, surgical factors and antimicrobial details were evaluated against hospital guidelines for overall adherence and domains of: antimicrobial choice, dose, re-dosing, timing and duration. Multiple regression analysis was used to determine risk factors for non-adherence. Hospital records were reviewed for post-operative infections at 7 and 30 days. RESULTS: Among 326 cases, overall guideline adherence was 39.6% but varied by domain and surgical subspecialty. Incorrect wound classification was associated with overall non-adherence on multivariate regression (odds ratio (OR): 2.59; P < 0.001). Incorrect antimicrobial choice was more likely in children with penicillin hypersensitivity (OR 138.34, P = 0.004) and incorrect dosing more likely in adolescent patients (OR 4.33; P = 0.004). Presence of invasive devices was associated with prolonged duration of antimicrobials (OR 2.92, P = 0.016). Only two post-operative infections were documented by 30 days, but data were insufficient to exclude mild infections managed in the community. CONCLUSIONS: SAP was suboptimal in children, with areas for improvement including better guidance on wound classification, allergy management and care for adolescent patients. Documented infections were rare, but mild infections were unable to be excluded due to limited post-discharge information.

Management and prevention of cytomegalovirus infection in paediatric hematopoietic stem cell transplant (HSCT) recipients: A binational survey.

CMV infection is an important cause of morbidity and mortality among HSCT recipients. Optimal strategies for prevention and management of CMV disease following haematopoietic stem cell transplantation remain uncertain. We conducted an online survey of Australasian paediatric allogeneic HSCT centres on management and prevention of CMV disease in this patient group. We asked for one response from a representative of the HSCT team and one from a representative of the ID team at each centre. All Australasian paediatric HSCT centres responded to our survey. Management of CMV in pre-transplant setting was consistent between centres. All centres used a pre-emptive strategy to prevent CMV disease, guided by quantitative CMV PCR. In the post-transplant post engraftment setting, all centres recommended using ganciclovir (5mg/kg/dose twice daily) as a first-line therapy for CMV reactivation or disease, with treatment duration of 14 days, provided declining CMV quantitative PCR. There was substantial variability of practice between centres in post-transplant management of CMV reactivation, especially during the pre-engraftment phase. Similarly, there was lack of uniformity in indication, dosing and duration of maintenance therapy. Divergence was noted between responses from HSCT and ID physicians within centres. This study identifies areas of uniformity and others of great variability in prevention and management strategies for CMV in paediatric HSCT. Data on CMV infection and management in HSCT patients should be routinely collected as part of prospective trials to inform guidelines and improve prevention and treatment of this important complication.

Exploring strategies to promote influenza vaccination of children with medical comorbidities: the perceptions and practices of hospital healthcare workers.

BACKGROUND: To explore how the influenza vaccine is promoted and delivered to children with medical comorbidities in the hospital setting, as well as the facilitators of and barriers to vaccination from the healthcare worker perspective. METHODS: Semi-structured interviews were conducted with staff members (n = 17) at a paediatric hospital in Sydney, Australia between April and July 2018. This included nurses, clinical nurse consultants, pediatricians and department heads. The interviews were transcribed and analysed iteratively to generate the major themes. RESULTS: Approaches used to promote and/or deliver the influenza vaccine varied among the participants. Some described the vaccine as an ingrained component of their clinical consultation. Others acknowledged that there was missed opportunities to discuss or provide the vaccine, citing competing priorities as well as a lack of awareness, time and resources. Participants perceived that some parents had concerns about safety and appropriateness of the vaccine for their child. While there was some support for sending reminders and/or educating patients through the hospital, there were differing perspectives on whether tertiary centres should be delivering the vaccine. CONCLUSION: Hospital-based interventions to increase vaccine uptake must consider the needs of staff. Easily accessible information and increased awareness of the recommendations among staff may lead to improved uptake in this hospital. Additional resources would be required to increase on-site delivery of the vaccine.

Hearing and neurodevelopmental outcomes for children with asymptomatic congenital cytomegalovirus infection: A systematic review.

INTRODUCTION: Congenital CMV is one of the commonest congenital infections and a recognised cause of sensorineural hearing loss and neurodevelopmental impairment. Ninety percent are clinically inapparent at birth but are reported to be at risk of developing such abnormalities throughout childhood, the extent of which requires further elucidation. METHODS: A systematic literature review was conducted using Medline and Embase databases, manual citation review, and personal libraries for articles reporting primary data on hearing and neurodevelopmental outcomes for children with asymptomatic congenital CMV. PROSPERO registration number CRD42015025407. RESULTS: Thirty-seven of 480 articles identified between 1969 and 2016 met the eligibility criteria. Twenty-nine of these contributed primary data on hearing outcomes and 20 on neurodevelopmental outcomes (12 of the 37 studies contributed data on both). Cumulative incidence of sensorineural hearing loss with follow-up to at least 5 years was 7% to 11%, which is more than healthy controls but less than children with symptomatic congenital CMV (34%-41%). The onset, course, and severity of hearing loss was variable with no reliable virological prognostic marker. In comparison to controls, children with asymptomatic congenital CMV did not perform worse than controls in neurodevelopmental assessments and performed better than children with symptomatic congenital CMV. CONCLUSIONS: Studies show children with asymptomatic congenital CMV are at increased risk of developing hearing loss but perform equally well on neurodevelopmental assessments when compared with healthy controls. There is no reliable virological marker to determine which infants will develop sequelae. Regular follow-up until school entry is supported by the literature.

Refugee children and their health, development and well-being over the first year of settlement: A longitudinal study.

AIM: This study aimed to describe refugee children, their families and settlement characteristics, and how their development and social-emotional well-being change over time. METHODS: We conducted a longitudinal study of 61 refugee children (6 months to 15 years) in an Australian setting, over 2009-2013 and measured child, family and settlement factors as well as physical health, development and social-emotional well-being (Strengths and Difficulties Questionnaire, SDQ). RESULTS: Questionnaires were completed with parents of 54 (89%) children at year 2 and 52 (100%) at year 3. Forty percent of parents had low levels of education, 30% of fathers were absent on arrival, 13% of children were born in refugee camps and 11% of parents self-disclosed previous trauma. Over time, there was increased parental employment (P = 0.001), improved English proficiency for partners (P = 0.02) and reduced stressful life events in the last 12 months (P = 0.003). At years 2 and 3, parents were studying English (96%; 76%), accessing government financial support (96%; 100%) and primary health care (98%; 87%), and feeling supported by their own (78%; 73%) or the general (69%; 63%) community. Fifteen percent of children had a chronic disease, and 13% were obese and overweight. In pre-school children, 27% had mild developmental problems in year 2; all were normal by year 3. Abnormal SDQ total difficulties scores reduced over time from 13 to 6% of children but this did not reach significance. CONCLUSION: Most refugee children have developmental and well-being outcomes within the normal range by year 3. However, a minority of children have persistently poor social-emotional outcomes.

Paediatrician beliefs and practices around influenza vaccination.

AIM: The uptake of influenza vaccination in children with high-risk medical conditions continues to be low in Australia and internationally. We aimed to determine Australian paediatricians' beliefs and practices around the influenza vaccination of children. METHODS: This was conducted as a cross sectional survey of paediatricians from two tertiary paediatric hospitals in Sydney. RESULTS: There were 101 participants. Influenza vaccination was not prioritised compared with other vaccines and clinical issues, with fewer than half of respondents strongly agreeing that influenza vaccination was useful. Paediatricians' knowledge of guidelines and recommendations in this area was suboptimal. Interventions thought most likely to improve vaccine coverage included better education of doctors, greater vaccine availability in outpatient clinics and automated reminder systems. CONCLUSION: The inclusion of influenza vaccine on the standard Australian immunisation schedule may be required to improve vaccine coverage in high-risk children.

Screening and Primary Care Access for Newly Arrived Paediatric Refugees in Regional Australia: A 5 year Cross-sectional Analysis (2007-12).

Aim: This study aimed to determine the prevalence of health conditions in newly arrived refugee children and access to timely heath screening. Methods: Cross-sectional data from screening of refugee children in regional Australia (2007-12) were analysed for health conditions and timeliness of primary care access. The health of 376 newly arrived refugee children (0-15 years) was assessed. Refugee children came from African (45%), Southeast Asian (29%) and Eastern Mediterranean (10%) regions. Access to primary care screening was present in 367 children (97% of arrivals). Completion of all recommended screening tests was 72%. Of 188 children with arrival and screening dates recorded, 88% were screened within 1 month and 96% within 6 months of arrival. Timely access of remaining children could not be assessed. Conclusion: Primary care was highly accessible to almost all newly arrived refugee children. Health screening was timely in those children with complete medical records.

Australia-wide point prevalence survey of the use and appropriateness of antimicrobial prescribing for children in hospital.

OBJECTIVES: To describe antimicrobial use in hospitalised Australian children and to analyse the appropriateness of this antimicrobial use. DESIGN: Multicentre single-day hospital-wide point prevalence survey, conducted in conjunction with the Antimicrobial Resistance and Prescribing in European Children study. SETTING: Eight children's hospitals across five Australian states, surveyed during late spring and early summer 2012. PATIENTS: Children and adolescents who were inpatients at 8 am on the day of the survey. MAIN OUTCOME MEASURES: Quantity and quality of antimicrobial prescribing. RESULTS: Of 1373 patients, 631 (46%) were prescribed at least one antimicrobial agent, 198 (31%) of whom were < 1 year old. The highest antimicrobial prescribing rates were in haematology and oncology wards (76% [95/125]) and paediatric intensive care units (55% [44/80]). Of 1174 antimicrobial prescriptions, 550 (47%) were for community-acquired infections, 175 (15%) were for hospital-acquired infections and 437 (37%) were for prophylaxis. Empirical treatment accounted for 72% of antimicrobial prescriptions for community-acquired infections and 58% for hospital-acquired infections (395 and 102 prescriptions, respectively). A total of 915 prescriptions (78%) were for antibacterials; antifungals and antivirals were predominantly used for prophylaxis. The most commonly prescribed antibacterials were narrow-spectrum penicillins (18% [164 prescriptions]), ß-lactam-ß-lactamase inhibitor combinations (15% [136]) and aminoglycosides (14% [128]). Overall, 957 prescriptions (82%) were deemed appropriate, but this varied between hospitals (range, 66% [74/112]) to 95% [165/174]) and specialties (range, 65% [122/187] to 94% [204/217]). Among surgical patients, 65 of 187 antimicrobial prescriptions (35%) were deemed inappropriate, and a common reason for this was excessive prophylaxis duration. CONCLUSION: A point prevalence survey is a useful cross-sectional method for quantifying antimicrobial use in paediatric populations. The value is significantly augmented by adding assessment of prescribing quality.

Adverse events following immunisation: Prospective cohort study evaluating Australian children presenting to specialist immunisation clinics.

OBJECTIVE: Prior experience of an adverse event following immunisation is a known barrier to vaccination. Limited Australian data evaluating adverse event recurrence among children exists to inform clinical decisions. We aimed to assess adverse event following immunisation recurrence among children with prior adverse events and to evaluate if family history increased adverse event risk. METHODS: A prospective cohort study was conducted from March 3rd until August 18th, 2023. Children ≤ 16 years with prior adverse events following immunisation in themselves or family were recruited from specialist immunisation clinics at two quaternary paediatric hospitals. Adverse event outcomes were collected via surveys administered at presentation, three, and eight days post vaccination, and analysed by key characteristics and potential risk factors. RESULTS: Forty three of forty nine (43/49, 87.8 %) children enrolled received further vaccines. Of those who completed the follow up surveys, 50.0 % (16/32) reported an adverse event. Recurrence of prior adverse events occurred for 23.3 % (10/43, 95 % CI: 11.8 % - 38.6 %) of the cohort. Two of twelve (2/12, 16.7 %) participants with prior serious adverse events who received further vaccines reported a serious adverse event recurrence. No post review serious adverse events were observed in children with prior non serious adverse events. Neurological conditions were a risk factor for prior (neurological condition 3/3 versus no neurological condition 2/40, p < 0.001) and post review (neurological condition 2/3 versus no neurological condition 0/28, p = 0.006) post vaccination seizures. Family history had no relationship to post review adverse events (family history 5/8 versus no family history 11/23, p = 0.685). CONCLUSION: Revaccination is safe for the majority of children with a personal or family history of adverse event following immunisation.

Mediastinal Nontuberculous Mycobacterial Infection in Children: A Multidisciplinary Approach.

BACKGROUND: Mediastinal infections due to nontuberculous mycobacteria remain an exceedingly rare entity. Most cases in the published literature do not include pediatric patients. Due to their clinical infrequency, poor response to antimicrobial therapy and often precarious anatomical location, the optimal management of these lesions can be challenging. METHODS: Retrospective medical record review of 4 pediatric cases of mediastinal nontuberculous mycobacteria infection was undertaken. Each child presented with nonspecific respiratory symptoms, including significant acute airway obstruction and required a range of investigations to confirm the diagnosis. Nonresponsiveness to conservative measures and antimycobacterial therapy ultimately resulted in surgical intervention to obtain clinical improvement. RESULTS: All 4 children had extensive evaluation and multidisciplinary involvement in otolaryngology, respiratory medicine, pediatric surgery, infectious diseases and cardiothoracic surgery. They all eventually had their disease debulked via thoracotomy in addition to prolonged antimycobacterial therapy, with successful clinical outcomes. CONCLUSIONS: Mediastinal nontuberculous mycobacteria infections in the pediatric population are rare and diagnostically challenging. A high clinical suspicion should be maintained, and multidisciplinary input sought. Targeted surgery with adjuvant medical therapy can reduce disease burden with minimal long-term morbidity.

Severe hemorrhagic meningoencephalitis due to Angiostrongylus cantonensis among young children in Sydney, Australia.

Angiostrongylus cantonensis is the most common cause of eosinophilic meningitis worldwide. We describe 2 cases among young children from Sydney, Australia, where locally acquired infection of children has not been reported previously. Both cases manifested as severe hemorrhagic meningoencephalitis, one resulting in death. Angiostrongyliasis must be considered in acute neurological presentations occurring among individuals who live in endemic areas.
