Data on imported infections in children and young people (CYP) are sparse. To describe imported infections in CYP arriving from malaria-endemic areas and presenting to UK emergency departments (ED) who were screened for malaria. This is a retrospective, multi-centre, observational study nested in a diagnostic accuracy study for malaria rapid diagnostic tests. Any CYP < 16 years presenting to a participating ED with a history of fever and travel to a malaria-endemic area between 1 January 2016 and 31 December 2017 and who had a malaria screen as a part of standard care were included. Geographical risk was calculated for the most common tropical infections. Of the 1414 CYP screened for malaria, 44.0% (n = 622) arrived from South Asia and 33.3% (n = 471) from sub-Saharan Africa. Half (50.0%) had infections common in both tropical and non-tropical settings such as viral upper respiratory tract infection (URTI); 21.0% of infections were coded as tropical if gastro-enteritis is included, with a total of 4.2% (60) cases of malaria. CYP diagnosed with malaria were 7.44 times more likely to have arrived from sub-Saharan Africa than from South Asia (OR 7.44, 3.78–16.41). A fifth of CYP presenting to participating UK EDs with fever and a history of travel to a malaria-endemic area and who were screened for malaria had a tropical infection if diarrhoea is included. A third of CYP had no diagnosis. CYP arriving from sub-Saharan Africa had the greatest risk of malaria.

Introduction: The early post-trauma period is a key time to provide psychological support to acutely injured children. This is often when they present to emergency departments (EDs) with their families. However, there is limited understanding of the feasibility of implementing psychological support for children and their families in EDs. The aim of this study was to explore UK and Irish ED clinicians’ perspectives on developing and implementing psychosocial care which educates families on their children’s post-trauma psychological recovery. Methods: Semi-structured individual and group interviews were conducted with 24 UK and Irish ED clinicians recruited via a paediatric emergency research network. Results: Clinicians expressed that there is value in offering psychological support for injured children and their families; however, there are barriers which can prevent this from being effectively implemented. Namely, the prioritisation of physical health, time constraints, understaffing, and a lack of training. Therefore, a potential intervention would need to be brief and accessible, and all staff should be empowered to deliver it to all families. Conclusion: Overall, participants’ views are consistent with trauma-informed approaches where a psychosocial intervention should be able to be implemented into the existing ED system and culture. These findings can inform implementation strategies and intervention development to facilitate the development and delivery of an accessible digital intervention for acutely injured children and their families.

Background Microscopy is the gold standard for malaria diagnosis but is dependent on trained personnel. Rapid diagnostic tests (RDTs) form the mainstay of diagnosis in endemic areas without access to high-quality microscopy. We aimed to evaluate whether RDT alone could rule out imported malaria in children presenting to UK emergency departments (EDs). Methods UK-based, multi-center, retrospective, diagnostic accuracy study. Included : any child <16 years presenting to ED with history of fever and travel to a malaria-endemic country, between 01/01/2016 and 31/12/2017. Diagnosis: microscopy for malarial parasites (clinical reference standard) and RDT (index test). UK Health Research Authority approval: 20/HRA/1341. Results There were 47 cases of malaria out of 1,414 eligible cases (prevalence 3.3%) in a cohort of children whose median age was 4 years (IQR 2–9), of whom 43% were female. Cases of Plasmodium falciparum totaled 36 (77%, prevalence 2.5%). The sensitivity of RDT alone to detect malaria infection due to any Plasmodium species was 93.6% (95% CI 82.5–98.7%), specificity 99.4% (95% CI 98.9–99.7%), positive predictive value 84.6% (95% CI 71.9–93.1%) and negative predictive value 99.8% (95% CI 99.4–100.0%). Sensitivity of RDT to detect P. falciparum infection was 100% (90.3–100%), specificity 98.8% (98.1–99.3%), positive predictive value 69.2% (54.9–81.2%, n = 46/52) and negative predictive value 100% (99.7–100%, n = 1,362/1,362). Conclusions RDTs were 100% sensitive in detecting P. falciparum malaria. However, lower sensitivity for other malaria species and the rise of pfhrp2 and pfhrp3 (pfhrp2/3) gene deletions in the P. falciparum parasite mandate the continued use of microscopy for diagnosing malaria.

Objective: To report the diagnostic test accuracy of dipstick urinalysis for the detection of urinary tract infections (UTIs) in febrile infants aged 90 days or less attending the emergency department (ED).Design: Retrospective cohort study.Patients: Febrile infants aged 90 days or less attending between 31 August 2018 and 1 September 2019.Main Outcome Measures: The sensitivity, specificity and predictive values of dipstick urinalysis in detecting UTIs defined as growth of ≥100 000 cfu/mL of a single organism and the presence of pyuria (>5 white blood cells per high-power field).Setting: Eight paediatric EDs in the UK/Ireland.Results: A total of 275 were included in the final analysis. There were 252 (92%) clean-catch urine samples and 23 (8%) were transurethral bladder catheter samples. The median age was 51 days (IQR 35-68.5, range 1-90), and there were 151/275 male participants (54.9%). In total, 38 (13.8%) participants had a confirmed UTI. The most sensitive individual dipstick test for UTI was the presence of leucocytes. Including 'trace' as positive resulted in a sensitivity of 0.87 (95% CI 0.69 to 0.94) and a specificity of 0.73 (95% CI 0.67 to 0.79). The most specific individual dipstick test for UTI was the presence of nitrites. Including trace as positive resulted in a specificity of 0.91 (95% CI 0.86 to 0.94) and a sensitivity of 0.42 (95% CI 0.26 to 0.59).Conclusion: Point-of-care urinalysis is moderately sensitive and highly specific for diagnosing UTI in febrile infants. The optimum cut-point to for excluding UTI was leucocytes (1+), and the optimum cut-point for confirming UTI was nitrites (trace).Trial Registration Number: NCT04196192.

Objective: To report the performance of clinical practice guidelines (CPG) in the diagnosis of serious/invasive bacterial infections (SBI/IBI) in infants presenting with a fever to emergency care in the UK and Ireland. Two CPGs were from the National Institutes for Health and Care Excellence (NICE guidelines NG51 and NG143) and one was from the British Society for Antimicrobial Chemotherapy (BSAC).Design: Retrospective multicentre cohort study.Patients: Febrile infants aged 90 days or less attending between the 31 August 2018 to 1 September 2019.Main Outcome Measures: The sensitivity, specificity and predictive values of CPGs in identifying SBI and IBI.Setting: Six paediatric Emergency Departments in the UK/Ireland.Results: 555 participants were included in the analysis. The median age was 53 days (IQR 32 to 70), 447 (81%) underwent blood testing and 421 (76%) received parenteral antibiotics. There were five participants with bacterial meningitis (1%), seven with bacteraemia (1%) and 66 (12%) with urinary tract infections. The NICE NG51 CPG was the most sensitive: 1.00 (95% CI 0.95 to 1.00). This was significantly more sensitive than NICE NG143: 0.91 (95% CI 0.82 to 0.96, p=0.0233) and BSAC: 0.82 (95% 0.72 to 0.90, p=0.0005). NICE NG51 was the least specific 0.0 (95% CI 0.0 to 0.01), and this was significantly lower than the NICE NG143: 0.09 (95% CI 0.07 to 0.12, p<0.0001) and BSAC: 0.14 (95% CI 0.1 to 0.17, p<0.0001).Conclusion: None of the studied CPGs demonstrated ideal performance characteristics. CPGs should be improved to guide initial clinical decision making.Trial Registration Number: NCT04196192. [ABSTRACT FROM AUTHOR]- Published

Aim: Attendances to emergency departments (EDs) in the UK are increasing, particularly for younger children. Community services are under increasing pressure and parents may preferentially bring their babies to the ED, even for non-urgent problems. This study aimed to characterise the presenting features, management and disposition of neonatal attendances to a children's ED (CED).Methods: Retrospective observational review of neonatal attendances (≤28 days) to the CED at Bristol Royal Hospital for Children (BRHC) from 01/01/2016 to 31/12/2016. Further information was obtained from investigation results and discharge summaries. Data abstracted included sex, age, referral method, presenting complaint, diagnosis, investigations and treatments.Results: Neonatal attendances increased from 655 to 1,205 from 2008 to 2016. The most common presenting complaints were breathing difficulty (18.1%) and vomiting (8.3%). The most common diagnoses were 'no significant medical problem' (41.9%) and bronchiolitis (10.5%). Half of neonatal attendances to the CED had no investigations performed and most (77.7%) needed advice or observation only.Conclusion: Many neonates presenting to the CED were well and discharged with observation only. This suggests potential for improving community management and in supporting new parents. Drivers of health policy should consider developing enhanced models of out of hospital care which are acceptable to clinicians and families. [ABSTRACT FROM AUTHOR]- Published

Objectives: The Pediatric Emergency Research Network (PERN) was launched in 2009 with the intent for existing national and regional research networks in paediatric emergency care to organise globally for the conduct of collaborative research across networks. Methods: PERN has grown from five to eight member networks over the past decade. With an executive committee comprising representatives from all member networks, PERN plays a supportive and collaborative rather than governing role. The full impact of PERN's facilitation of international collaborative research, although somewhat difficult to quantify empirically, can be measured indirectly by the observed growth of the field, the nature of the increasingly challenging research questions now being addressed and the collective capacity to generate and implement new knowledge in treating acutely ill and injured children. Results: Beginning as a pandemic response studying H1N1 influenza risk factors in children, PERN research has progressed to multiple observational studies and ongoing global randomised controlled trials (RCTs). As a recent example, PERN has developed sufficient network infrastructure to enable the rapid initiation of a prospective observational study in response to the current COVID‐19 pandemic. Conclusions: Following its success with developing global research, the PERN goal now is to promote the implementation of scientific advances into everyday clinical practice by: (i) expanding the capacity for global RCTs; (ii) deepening the focus on implementation science; (iii) increasing attention to healthcare disparities; and (iv) expanding PERN's reach into resource‐restricted regions. Through these actions, PERN aims to meet the needs of acutely ill and injured children throughout the world. [ABSTRACT FROM AUTHOR]
