Analysis of guideline recommendations for treatment of asthma exacerbations in children: a Pediatric Emergency Research Networks (PERN) study.

RATIONALE: There is significant practice variation in acute paediatric asthma, particularly severe exacerbations. It is unknown whether this is due to differences in clinical guidelines. OBJECTIVES: To describe and compare the content and quality of clinical guidelines for the management of acute exacerbations of asthma in children between geographic regions. METHODS: Observational study of guidelines for the management of acute paediatric asthma from institutions across a global collaboration of six regional paediatric emergency research networks. MEASUREMENTS AND MAIN RESULTS: 158 guidelines were identified. Half provided recommendations for at least two age groups, and most guidelines provided treatment recommendations according to asthma severity.There were consistent recommendations for the use of inhaled short-acting beta-agonists and systemic corticosteroids. Inhaled anticholinergic therapy was recommended in most guidelines for severe and critical asthma, but there were inconsistent recommendations for its use in mild and moderate exacerbations. Other inhaled therapies such as helium-oxygen mixture (Heliox) and nebulised magnesium were inconsistently recommended for severe and critical illness.Parenteral bronchodilator therapy and epinephrine were mostly reserved for severe and critical asthma, with intravenous magnesium most recommended. There were regional differences in the use of other parenteral bronchodilators, particularly aminophylline.Guideline quality assessment identified high ratings for clarity of presentation, scope and purpose, but low ratings for stakeholder involvement, rigour of development, applicability and editorial independence. CONCLUSIONS: Current guidelines for the management of acute paediatric asthma exacerbations have substantial deficits in important quality domains and provide limited and inconsistent guidance for severe exacerbations.

International perspective on research priorities and outcome measures of importance in the care of children with acute exacerbations of asthma: a qualitative interview study.

BACKGROUND: Acute exacerbations of asthma are common in children, however, treatment decisions for severe exacerbations are challenging due to a lack of robust evidence. In order to create more robust research, a core set of outcome measures needs to be developed. In developing these outcomes, it is important to understand the views of clinicians who care for these children in particular, views that relate to outcome measures and research priorities. METHODS: To determine the views of clinicians, a total of 26 semistructured interviews based on the theoretical domains framework were conducted. These included experienced clinicians from emergency, intensive care and inpatient paediatrics across 17 countries. The interviews were recorded, and later transcribed. All data analyses were conducted in Nvivo by using thematic analysis. RESULTS: The length of stay in hospital and patient-focused parameters, such as timing to return to school and normal activity, were the most frequently highlighted outcome measures, with clinicians identifying the need to achieve a consensus on key core outcome measure sets. Most research questions focused on understanding the best treatment options, including the role of novel therapies and respiratory support. CONCLUSION: Our study provides an insight into what research questions and outcome measures clinicians view as important. In addition, information on how clinicians define asthma severity and measure treatment success will assist with methodological design in future trials. The current findings will be used in parallel with a further Paediatric Emergency Research Network study focusing on the child and family perspectives and will contribute to develop a core outcome set for future research.

How much time do doctors spend providing care to each child in the ED? A time and motion study.

BACKGROUND: The total time per patient doctors spend providing care in emergency departments (EDs) has implications for the development of evidence-based ED staffing models. We sought to measure the total time taken by doctors to assess and manage individual paediatric patients presenting to two EDs in the Western Cape, South Africa and to compare these averages to the estimated benchmarks used regionally to calculate ED staffing allocations. METHODS: We conducted a cross-sectional, observational study applying time and motion methodology, using convenience sampling. Data were collected over a 5-week period from 11 December 2015 to 18 January 2016 at Khayelitsha District Hospital Emergency Centre and Tygerberg Hospital Paediatric Emergency and Ambulatory Unit. We assessed total doctor time for each patient stratified by acuity level using the South African Triage Scale. RESULTS: Care was observed for a total of 100 patients. Median age was 21 months (IQR 8-55). Median total doctor time per patient (95% CI) was 31 (22 to 38), 39 (31 to 63), 48 (32 to 63) and 96 (66 to 122) min for triage categories green, yellow, orange and red, respectively. Median timing was significantly higher than the estimated local benchmark for the lowest acuity 'green' triage category (31 min (22 to 38) vs 15 min; p=0.001) and the highest acuity 'red' category (96 min (66 to 122) vs 50 min; p=0.002). CONCLUSION: Doctor time per patient increased with increasing acuity of triage category and exceeded estimated benchmarks for the highest and lowest acuities. The distinctive methodology can easily be extended to other settings and populations.

Triage and resuscitation tools for low and middle income countries: how to catch the killer?

Under-5 mortality rates in low and middle-income countries (LMIC) remain high. One major contributing factor is the failure to recognise critically unwell children when they first present to hospital. This leads to delayed or inadequate resuscitation and an increased risk of death.Triage is a key skill in this setting to sort the queue and prioritise patients, even when staff and equipment are scarce. In LMIC, children generally present late in their illness and often have progressed to some degree of multiorgan dysfunction.Following triage, a structured systematic primary survey is critical to ensure the detection of subtle signs of multiorgan dysfunction. Repeated physiological assessments of the child guide subsequent resuscitation management decisions, which depend somewhat on the resources available.It is possible to achieve significant improvements in survival of critically unwell children presenting for emergency care in the resource-limited setting. The three key steps in the patient's journey that we can influence in emergency care are triage, primary survey and initial stabilisation. Resources that address these steps have been developed for all settings. However, these resources were developed in a specific clinical context, and must therefore be adapted to local structures and processes. A systematic approach to triage and resuscitation saves lives.

A cross sectional study of the availability of paediatric emergency equipment in South African emergency units.

BACKGROUND: Despite children representing a significant proportion of Emergency Unit (EU) attendances globally, it is concerning that many healthcare facilities are inadequately equipped to deliver paediatric resuscitation. The rapid availability of a full range of paediatric emergency equipment is critical for delivery of effective, best-practice resuscitation. This study aimed to describe the availability of essential, functional paediatric emergency resuscitation equipment on or close to the resuscitation trolley, in 24-hour EUs in Cape Town, South Africa. METHODS: A cross sectional study was conducted over a six-month period in government funded hospital EUs, providing 24-hour emergency paediatric care within the Cape Town Metropole. A standardised data collection sheet of essential resuscitation equipment expected to be available in the resuscitation area, was used. Items were considered to be available if at least one piece of equipment was present. Functionality of available equipment was defined as: equipment that hadn't expired, whose original packaging was not outwardly damaged or compromised and all components were present and intact. RESULTS: Overall, a mean of 43% (30/69) of equipment was available on the resuscitation trolley across all hospitals. The overall mean availability of equipment in the resuscitation area was 49% (34/69) across all hospitals. Mean availability of functional equipment was 42% (29/69) overall, 41% (28/69) at district-level hospitals, and 45% (31/69) at regional/tertiary hospitals. CONCLUSION: Essential resuscitation equipment for children is insufficiently available at district-level and higher hospitals in the Cape Town Metropole. This is a modifiable barrier to the provision of high-quality paediatric emergency care.

The burgeoning role of global health diplomacy to alleviate suffering of cancer patients in low- and middle-income countries.

The science of global health diplomacy (GHD) consists of cross-disciplinary, multistakeholder credentials comprised of national security, public health, international affairs, management, law, economics and trade policy. GHD is well placed to bring about better and improved multilateral stakeholder leverage and outcomes in the prevention and control of cancer. It is important to create an evidence base that provides clear and specific guidance for health practitioners in low- and middle-income countries (LMICs) through involvement of all stakeholders. GHD can assist LMICs to negotiate across multilateral stakeholders to integrate prevention, treatment and palliative care of cancer into their commercial and trade policies.

Acute severe paediatric asthma: study protocol for the development of a core outcome set, a Pediatric Emergency Reserarch Networks (PERN) study.

BACKGROUND: Acute severe childhood asthma is an infrequent, but potentially life-threatening emergency condition. There is a wide range of different approaches to this condition, with very little supporting evidence, leading to significant variation in practice. To improve knowledge in this area, there must first be consensus on how to conduct clinical trials, so that valid comparisons can be made between future studies. We have formed an international working group comprising paediatricians and emergency physicians from North America, Europe, Asia, the Middle East, Africa, South America, Central America, Australasia and the United Kingdom. METHODS/DESIGN: A 5-stage approach will be used: (1) a comprehensive list of outcomes relevant to stakeholders will be compiled through systematic reviews and qualitative interviews with patients, families, and clinicians; (2) Delphi methodology will be applied to reduce the comprehensive list to a core outcome set; (3) we will review current clinical practice guidelines, existing clinical trials, and literature on bedside assessment of asthma severity. We will then identify practice differences in tne clinical assessment of asthma severity, and determine whether further prospective work is needed to achieve agreement on inclusion criteria for clinical trials in acute paediatric asthma in the emergency department (ED) setting; (4) a retrospective chart review in Australia and New Zealand will identify the incidence of serious clinical complications such as intubation, ICU admission, and death in children hospitalized with acute severe asthma. Understanding the incidence of such outcomes will allow us to understand how common (and therefore how feasible) particular outcomes are in asthma in the ED setting; and finally (5) a meeting of the Pediatric Emergency Research Networks (PERN) asthma working group will be held, with invitation of other clinicians interested in acute asthma research, and patients/families. The group will be asked to achieve consensus on a core set of outcomes and to make recommendations for the conduct of clinical trials in acute severe asthma. If this is not possible, the group will agree on a series of prioritized steps to achieve this aim. DISCUSSION: The development of an international consensus on core outcomes is an important first step towards the development of consensus guidelines and standardised protocols for randomized controlled trials (RCTs) in this population. This will enable us to better interpret and compare future studies, reduce risks of study heterogeneity and outcome reporting bias, and improve the evidence base for the management of this important condition.

Noninvasive Ventilation During Pediatric and Neonatal Critical Care Transport: A Systematic Review.

OBJECTIVES: Noninvasive ventilation is increasingly used in neonatal and pediatric patients, but the intensive care transport setting is lagging in terms of availability of noninvasive ventilation for children. The objective of this systematic review of the literature was to answer the question: In children 0 days to 18 years old, who are hospitalized with acute respiratory distress and require critical care transport, is noninvasive ventilation effective and safe during transport? DATA SOURCES: MEDLINE via PubMed, EMBASE (via Scopus), Cochrane Central Register of Controlled Trials, African Index Medicus, Web of Science Citation Index, and the World Health Organization Trials Registry. STUDY SELECTION: Two reviewers independently reviewed all identified studies for eligibility and quality. DATA EXTRACTION: Data were extracted independently by two reviewers using piloted data extraction forms. DATA SYNTHESIS: Data were not synthesized due to nature of studies included. RESULTS: A total of 1,287 records were identified; no randomized or quasi-randomized controlled trials were found. Eight observational studies, enrolling 858 patients were included, of these 60.4% were neonatal ICU and 39.6% were nonneonatal ICU patient transports. The mode of noninvasive ventilation during transport was continuous positive airway pressure in seven studies (708 patients) and high-flow nasal cannula in one study (150 patients). During transport on noninvasive ventilation, three of 858 patients (0.4%) required either intubation or escalation of noninvasive ventilation. In the 24 hours following transfer, 63 of 650 children (10%) transferred on noninvasive ventilation were intubated. The odds of intubation within 24 hours were significantly higher for continuous positive airway pressure transfer 60 of 500 (12%) compared with high-flow nasal cannula three of 150 (2%): odds ratio (95% CI) 6.68 (2.40-18.63), p value equals to 0.00003. Minor adverse events occurred in 1-4% of noninvasive ventilation transports. CONCLUSIONS: This review found observational study evidence of a rate of intubation or escalation of 0.4% during noninvasive ventilation transport of children 0-18 years old, with an in-transport adverse event rate of 1-4%. Further studies are required. If randomized trials are not possible, it is suggested that well-conducted observational studies are reported in a more standardized manner.

Paediatric emergency and acute care in resource poor settings.

Acute care of seriously ill children is a global public health issue, and there is much scope for improving quality of care in hospitals at all levels in many developing countries. We describe the current state of paediatric emergency and acute care in the least developed regions of low and middle income countries and identify gaps and requirements for improving quality. Approaches are needed which span the continuum of care: from triage and emergency treatment, the diagnostic process, identification of co-morbidities, treatment, monitoring and supportive care, discharge planning and follow-up. Improvements require support and training for health workers and quality processes. Effective training is that which is ongoing, combining good technical training in under-graduate courses and continuing professional development. Quality processes combine evidence-based guidelines, essential medicines, appropriate technology, appropriate financing of services, standards and assessment tools and training resources. While initial emergency treatment is based on common clinical syndromes, early differentiation is required for specific treatment, and this can usually be carried out clinically without expensive tests. While global strategies are important, it is what happens locally that makes a difference and is too often neglected. In rural areas in the poorest countries in the world, public doctors and nurses who provide emergency and acute care for children are revered by their communities and demonstrate daily that much can be carried out with little.
