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.

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.

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.

A retrospective review of paediatric head injuries in Asia - a Pan Asian Trauma Outcomes Study (PATOS) collaboration.

OBJECTIVE: We aim to examine the mechanisms of head-injured children presenting to participating centres in the Pan Asian Trauma Outcomes Study (PATOS) and to evaluate the association between mechanism of injury and severe outcomes. DESIGN AND SETTING: We performed a retrospective review of medical records among emergency departments (EDs) of eight PATOS centres, from September 2014 - August 2015. PARTICIPANTS: We included children <16 years old who presented within 24 hours of head injury and were admitted for observation or required a computed tomography (CT) of the brain from the ED. We excluded children with known coagulopathies, neurological co-morbidities or prior neurosurgery. We reviewed the mechanism, intent, location and object involved in each injury, and the patients' physical findings on presentation. OUTCOMES: Primary outcomes were death, endotracheal intubation or neurosurgical intervention. Secondary outcomes included hospital and ED length of stay. RESULTS: 1438 children were analysed. 953 children (66.3%) were male and the median age was 5.0 years (IQR 1.0-10.0). Falls predominated especially among children younger than 2 years (82.9%), while road traffic injuries were more likely to occur among children 2 years and above compared with younger children (25.8% vs 11.1%). Centres from upper and lower middle-income countries were more likely to receive head injured children from road traffic collisions compared with those from high-income countries (51.4% and 40.9%, vs 10.9%, p<0.0001) and attended to a greater proportion of children with severe outcomes (58.2% and 28.4%, vs 3.6%, p<0.0001). After adjusting for age, gender, intent of injury and gross national income, traffic injuries (adjusted OR 2.183, 95% CI 1.448 to 3.293) were associated with severe outcomes, as compared with falls. CONCLUSIONS: Among children with head injuries, traffic injuries are independently associated with death, endotracheal intubation and neurosurgery. This collaboration among Asian centres holds potential for future prospective childhood injury surveillance.

Predictors of Outcome in Children with Status Epilepticus during Resuscitation in Pediatric Emergency Department: A Retrospective Observational Study.

OBJECTIVES: To study the clinical profile and predictors of outcome in children with status epilepticus (SE) during resuscitation in pediatric emergency department. MATERIALS AND METHODS: This retrospective study was carried out in a tertiary care teaching hospital. Admission and resuscitation data of children, aged between 1 month and 12 years, treated for SE, between September 2013 and August 2014, were extracted using a standard data collection form. Our SE management protocol had employed a modified pediatric assessment triangle to recognize and treat acute respiratory failure, cardiovascular dysfunction (CD), and subtle SE until all parameters resolved. Continuous positive airway pressure, fluid boluses based on shock etiology, inotropes, and cardiac safe anticonvulsants were the other modifications. Risk factors predicting mortality during resuscitation were analyzed using univariate and penalized logistic regression. RESULTS: Among 610 who were enrolled, 582 (95.4%) survived and 28 (4.6%) succumbed. Grunt odds ratio (OR): 3.747 (95% confidence interval [CI]: 1.035-13.560), retractions OR: 2.429 (95% CI: 1.036-5.698), rales OR: 10.145 (95% CI: 4.027-25.560), prolonged capillary refill time OR: 3.352 (95% CI: 1.339-8.388), and shock requiring >60 mL/kg fluids OR: 2.439 (95% CI 1.040-5.721) were associated with 2-3 times rise in mortality. Inappropriate prehospital treatment and CD were the significant predictors of mortality OR: 7.82 (95% CI 2.10-29.06) and 738.71 (95% CI: 97.11-999), respectively. Resolution of CD was associated with improved survival OR: 0.02 (95% CI: 0.003-0.17). CONCLUSION: Appropriate prehospital management and treatment protocol targeting resolution of CD during resuscitation could reduce mortality in children with SE.

Efficacy of nebulised budesonide versus oral prednisolone in acute severe asthma.

OBJECTIVE: To compare the efficacy of nebulised budesonide with that of oral prednisone in the treatment of acute severe asthma in children. METHODS: Children aged 5-12 y with acute exacerbation of bronchial asthma were included. The study (budesonide) group received budesonide respirator solution (800 µg) at intervals of 20 min and a single dose of placebo tablets. The control (prednisolone) group received placebo solution at intervals of 20 min and a single dose of oral prednisolone (2 mg/kg). Both groups received three doses of nebulised salbutamol (0.15 mg/kg). Heart rate, respiratory rate, oxygen saturation, PEFR (Peak Expiratory Flow Rate) and fitness for discharge were assessed. RESULTS: Both groups showed a progressive decrease in tachycardia with treatment, but it was significantly greater in study group (p = 0.0002). There was significant decrease in tachypnea and improvement in oxygen saturation in both groups, but the difference between the groups (p = 0.334 and p = 0.814 respectively) was not significant. There was significant improvement in PEFR values in budesonide group (p = 0.024). Both groups showed significant improvement in clinical severity scores at the end of 2 h (p < 0.0001). Budesonide group had significantly higher proportion of patients fit for discharge at 2 h (based on clinical severity scores) (p = 0.0278). CONCLUSIONS: Nebulised budesonide significantly improves PEFR levels and fitness for discharge at 2 h when compared to oral prednisolone in children between 5 and 12 y with acute severe asthma.

GAP between knowledge and skills for the implementation of the ACCM/PALS septic shock guidelines in India: is the bridge too far?

OBJECTIVE: To determine whether physicians were aware of and had the skills to implement the American College of Critical Care Medicine/Pediatric Advanced Life Support Course septic shock protocol. DESIGN: A cross-sectional questionnaire survey. SETTING: Four academic institutions in Chennai, Manipal, Mangalore, and Trivandrum - cities representing the three southern states of Tamil Nadu, Karnataka, and Kerala, respectively, between February and April 2006. INTERVENTIONS: Pre and post lecture questions. They were evaluated using 11 questions testing knowledge and 10 questions testing their comfort level in performing interventions related to the initial resuscitation in septic shock. MEASUREMENT AND MAIN RESULT: The ACCM/PALS sepsis guidelines were taught during the PALS course conducted in the four academic institutions. A total of 118 delegates participated, of whom 114 (97%) were pediatricians and four (3%) were anaesthetists. The overall mean number of correct responses for the 11 questions testing knowledge before and after the lecture was 2.1 and 4.07, respectively P=0.001(paired t test). Although, 42% of the respondents (n=50) were aware of the ACCM guidelines, 88% (n=104) did not adhere to it in their practice. A total of 86% (n=101) and 66% (n=78) did not feel comfortable titrating inotropes or intubating in the ED; 78% (n=92) and 67% (n=78), respectively felt that central venous access (CVA) and arterial pressure (AP) monitoring were unimportant in the management of fluid refractory shock. Of the physicians, 20% (n=24) had never intubated a patient, 78% (n=92) had not introduced a central venous catheter, and 76% (n=90) had never introduced an intra-arterial catheter. CONCLUSIONS: In view of the lack of skills and suboptimal knowledge, the ACCM/PALS sepsis guidelines may be inappropriate in its current format in the Indian setting. More emphasis needs to be placed on educating community pediatricians with a simpler clinical protocol, which has the potential to save many more children.

A prospective randomized controlled study of two fluid regimens in the initial management of septic shock in the emergency department.

OBJECTIVES: To compare the impact of 40 mL/kg of fluid over 15 minutes followed by dopamine and further titration of therapy to achieve therapeutic goals (study protocol) versus 20 mL/kg over 20 minutes up to a maximum of 60 mL/kg over 1 hour followed by dopamine (control protocol) in septic shock. DESIGN AND SETTING: Prospective randomized controlled study in the emergency department of a public hospital in India. PATIENTS: One hundred forty-seven children older than 1 month presenting with septic shock were enrolled into the study. OUTCOME MEASURES: Hospital mortality (primary outcome), 72-hour survival, achievement of therapeutic goals of shock resolution, incidence of hypoxia, hepatomegaly, intubation at 20, 40, and 60 minutes (secondary outcomes) were compared between the arms. RESULTS: Seventy-four and 73 children were assigned to the study and control group, respectively. Overall mortality was 17.6%, 26 deaths with 13 in each arm. Mortality in the study cohort was lower than our historical mortality of 50% (P<0.0001), 95% confidence interval (CI), 11.9-24.8. Cumulative survival at 72 hours was 72.5% (95% CI, 58.9-86.1) and 77.6% (95% CI, 66.0%-89.2%) in the control and study groups, respectively. Resolution of shock in the emergency department was associated with survival odds ratio (OR) 9.2 (95% CI, 2.1-40.8). Rapidity of achieving therapeutic goals was not significantly different between groups. Intubation rates were also the same (46.5% in the control group versus 55% in the study group; P=0.28). At 20 minutes, 35.6% of the control group and 70% of the study group had hepatomegaly (P<0.01). CONCLUSION: There was no difference in the overall mortality, rapidity of shock resolution, or incidence of complications between the groups. The occurrence of hepatomegaly at 20 minutes following 40 mL/kg is of concern in settings with limited access to post-resuscitation ventilator care.

Mortality after admission in the pediatric emergency department: a prospective study from a referral children's hospital in southern India.

OBJECTIVE: Data on outcomes after admission in pediatric emergency departments are sparse in India. Our objectives were to determine the clinical and epidemiologic profile of acutely ill children and to identify risk factors for mortality. DESIGN: Prospective, longitudinal study, conducted in 1999. SETTING: Pediatric emergency department at the Institute of Child Health, a multiple specialty, children's referral, public hospital in Madras, India. PATIENTS: Children of <12 yrs of age who required acute care in the pediatric emergency department (excluding minor illnesses) recruited consecutively during a 2-mo period. MEASUREMENTS AND MAIN RESULTS: Data included demographic variables, clinical profile, diagnoses, therapy, and in-hospital mortality after admission (outcome). In a cohort of 1155 children, there were 141 deaths (12.2%). Mortality was highest in the neonatal group (17.8%), which accounted for 67% of all deaths. Among neonates, breathlessness, poor feeding, birth asphyxia, and prematurity were the most common presenting problems. Among the postneonates, breathlessness, fever, and fits ranked high. Multivariate analyses to determine risk factors were done separately for neonates, postneonates, and those aged 1-12 yrs. Among neonates, age of 1 yr, central-peripheral temperature gap and respiratory failure were major risk factors. CONCLUSIONS: The incidence of mortality is high in our setting and further research is needed to identify causes of preventable deaths. Children presenting with signs of hypoperfusion and respiratory failure had poor outcomes. This raises the concern that children may be presenting late, with advanced, severe illness to our pediatric emergency department. The data also suggest that identification of serious illness in children is possible with simple clinical signs and symptoms.
