“…Data extraction included authors, year of publication, geographic location, number of patients, primary, secondary, and other outcomes used, and study interventions including dosing and timing of medication administered. The systematic review was prospectively registered in the PROS-PERO database (CRD42017055331), and has recently been published [46]. We identified 35 published papers and four registered study protocols.…”

“…Other primary outcomes identified included bedside tests of respiratory function (11/56; 20%) and measures of length of stay (9/56; 16%). There were a total of 60 different secondary outcomes; the most common were various measures of length of stay (24/60; 40%) and adverse events (11/60; 18%) [46].…”

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 (Continued on next page)

Background. Acute severe childhood asthma is an infrequent, but potentially life-threatening emergency presentation. 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 five-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) A 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 regarding bedside assessment of asthma severity. We will then identify practice differences in clinical assessment of asthma severity, and determine whether further prospective work is needed to achieve agreement on inclusion criteria for clinical trials on acute paediatric asthma in the emergency department setting; (4) A retrospective chart review in Australia and New Zealand will identify the incidence of serious clinical complications in children hospitalized with acute severe asthma, such as intubation, ICU admission, and death. Understanding the incidence of such outcomes will allow us to understand how common (and therefore how feasible) particular outcomes are in an asthma ED population; (5) Finally, a meeting of the 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 on 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 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.
