The impact of national guidelines on the assessment and management of acute paediatric asthma presenting at a tertiary children's emergency department

[Asthma crisis in emergency departments in Spain: what is our usual practice?]

BACKGROUND

Despite there being various guidelines and consensus statements on asthma, great variability still exists in its treatment approach; although this has been little discussed in Emergency Departments (ED).

OBJECTIVE

To describe the usual management of asthma exacerbations in Spanish ED, and to determine the degree of variability among different professionals, as well as analyse factors that may influence their management.

MATERIAL AND METHODS

A questionnaire was developed based on clinical cases, which was distributed among members of the Spanish Society of Paediatric Emergencies and attendees at the meeting in 2011.

RESULTS

A total of 300 surveys were analysed. In 190 cases the place of work was in a tertiary care hospital. There was high agreement in the assessment of the severity of the cases mentioned. Over 90% use inhaled β2 agonists in mild asthma exacerbations, 75.3% used oral corticosteroids in moderate exacerbations, and 79% use ipratropium bromide in severe exacerbations. Almost all (98%) considered Therapeutic Education important in the Emergency Department. Only 8 (2.7%) used peak expiratory flow measurements. Respondents working in a tertiary hospital used severity scales more frequently (90.5% vs 80%, P=.009) and administered parenteral corticosteroids less frequently (53.2% vs 66.4%, P=.017).

CONCLUSIONS

Although a high percentage of paediatricians working in the ED follow Clinical Practice Guidelines, some different points of the approach among professionals have been identified.

Early administration of systemic corticosteroids reduces hospital admission rates for children with moderate and severe asthma exacerbation

STUDY OBJECTIVE

The variable effectiveness of clinical asthma pathways to reduce hospital admissions may be explained in part by the timing of systemic corticosteroid administration. We examine the effect of early (within 60 minutes [SD 15 minutes] of triage) versus delayed (>75 minutes) administration of systemic corticosteroids on health outcomes.

METHODS

We conducted a prospective observational cohort of children aged 2 to 17 years presenting to the emergency department with moderate or severe asthma, defined as a Pediatric Respiratory Assessment Measure (PRAM) score of 5 to 12. The outcomes were hospital admission, relapse, and length of active treatment; they were analyzed with multivariate logistic and linear regressions adjusted for covariates and potential confounders.

RESULTS

Among the 406 eligible children, 88% had moderate asthma; 22%, severe asthma. The median age was 4 years (interquartile range 3 to 8 years); 64% were male patients. Fifty percent of patients received systemic corticosteroids early; in 33%, it was delayed; 17% of children failed to receive any. Overall, 36% of patients were admitted to the hospital. Compared with delayed administration, early administration reduced the odds of admission by 0.4 (95% confidence interval 0.2 to 0.7) and the length of active treatment by 0.7 hours (95% confidence interval -1.3 to -0.8 hours), with no significant effect on relapse. Delayed administration was positively associated with triage priority and negatively with PRAM score.

CONCLUSION

In this study of children with moderate or severe asthma, administration of systemic corticosteroids within 75 minutes of triage decreased hospital admission rate and length of active treatment, suggesting that early administration of systemic corticosteroids may allow for optimal effectiveness.

Adherence to pediatric asthma guidelines in the emergency department: a survey of knowledge, attitudes and behaviour among health care professionals

BACKGROUND

Despite strong evidence for using clinical care pathways to manage acute pediatric asthma, adherence remains suboptimal.

OBJECTIVES

To elicit information from health care professionals regarding their knowledge, attitudes and use of a care pathway for acute childhood asthma.

METHODS

A cross-sectional, self-administered survey of physicians, nurses and respiratory therapists who worked in the emergency department at the Montreal Children's Hospital (Montreal, Quebec) from August to December 2007 was conducted. The survey assessed knowledge, attitude toward and agreement with the care pathway, as well as its use four years after its implementation.

RESULTS

Of the 128 health care professionals surveyed, 72 (56%) responded. Of these, 99% reported being familiar with the pathway, more than 90% agreed with its use for mild and moderate asthma, while 79% agreed with its use for severe asthma. For 99% of health care professionals, the advantages of using the pathway outweighed the disadvantages; however, 64% admitted to making variations to the pathway. Although 92% of respondents reported that they were quite comfortable with using the asthma severity Pediatric Respiratory Assessment Measure, only 53% and 36% correctly identified the severity score cut-offs for moderate and severe asthma, respectively. Seventeen per cent of respondents underestimated the delay of onset of action of oral corticosteroids, while 36% of physicians incorrectly believed that a higher than necessary dose was recommended for ipratropium bromide.

CONCLUSIONS

Results of the survey confirmed that the health care professionals queried had a positive attitude toward the pediatric asthma care pathway. Knowledge gaps and the balance between standardization versus individualization of care may be key elements to explain suboptimal adherence to the pathway.

Focusing the focus group: impact of the awareness of major factors contributing to non-adherence to acute paediatric asthma guidelines

RATIONALE

The administration of oral corticosteroids within the first hour in the emergency department is associated with reduced hospitalization rates in children with moderate and severe asthma, yet less than half of patients benefit from this recommendation. To ensure patients receive recommended treatment, a clear understanding of what is causing suboptimal care management is needed. The assessment of barriers and solutions to optimal care is often done without a thorough examination of the factors associated with non-adherence.

OBJECTIVE

To evaluate whether knowledge of factors associated with delayed administration of systemic corticosteroids modifies the focus and prioritization of barriers and solutions identified by focus groups.

METHODS

We conducted two parallel focus groups of emergency health care professionals - one group informed and the other non-informed of key factors. Both groups received a presentation on the acute asthma guidelines, the evidence supporting its recommendations, and current practice. In addition, the informed group was provided with the factors associated and not associated with delayed administration. The groups were given 20 minutes to discuss barriers and solutions, with 5 minutes each for voting for the main barriers and solutions. Group difference in the misdirection of discussion was measured as time spent discussing barriers that were shown not to be associated with systemic corticosteroids. Prioritization of barriers and solutions was based on group endorsement.

RESULTS

The non-informed group spent more time discussing barriers not associated with delayed administration (15 vs. 2 minutes, P = 0.05). Although the non-informed group proposed more solutions, most were to overcome barriers not associated with delayed administration. Of the main barriers and solutions identified by each group, only one barrier and solution were similar between the two groups: emergency department overcrowding and administrating corticosteroids at triage.

CONCLUSION

The awareness of objective factors of non-adherence enabled a more directed discussion on relevant barriers and solutions, affecting prioritization of each. The administration of oral corticosteroids at triage appears to be the best solution to overcome delayed administration.

Medical audit on children with asthma in an Emergency Department

OBJECTIVE

To carry out a medical audit or evaluation and improvement procedure on the management of children with asthmatic crises in our Emergency Department (ED).

MATERIAL AND METHODS

We carried out a retrospective audit between January and March 2007, analysing the medical records of a random sample of 50 patients aged 2-14 years consulting our ED for asthmatic crises. Following the international guides, we first selected 17 explicit indicators divided into four domains: "evaluation", "examination", "diagnostic resources", and "treatment and conditions at discharge".

RESULTS

Indicators' compliance proved unequal; it was scarce for cause of asthma crisis (32%); degree of severity (18%); and supportive treatment (24%). Auscultation was registered in 100%, but respiratory frequency only in 49%, and peak flow in 0%. A total of 78% of the patients were treated in the ED, in all cases with beta-mimetic agents, and with systemic corticosteroids in 12%. The result of treatment was registered in only 69% of cases. The medical documentation of resident doctors was not signed by the staff.

CONCLUSIONS

We identified the following weak points: failure to determine the degree of severity; lack of specification of the details of the crisis (prior duration, treatment at home, supportive treatment); scant asthma background history; and deficient recording of respiratory frequency and peak flow. We propose improving the anamnesis, recording respiratory frequency, with the introduction of tools to measure peak flow, specification of treatment response, and the development of a simpler and more practical protocol, with the performance of a re-audit.

Management of childhood asthma in Western Australia

AIMS

The study aimed to determine how childhood asthma is managed in Western Australia by general practitioners (GPs) and specialist paediatricians.

METHODS

A questionnaire survey was sent to 992 GPs and specialist paediatricians, asking about practice and preferences regarding maintenance management of childhood asthma and treatment of acute asthma. Questions about asthma in infants, pre-school and school-aged children were asked separately.

RESULTS

The overall response rate was 24.7%, with 188/878 (21.4%) of GPs and 44/62 (71.0%) of paediatricians returning the questionnaire. The decision to start maintenance therapy was generally based on symptom frequency and severity. The first choice for maintenance treatment in all age groups was inhaled corticosteroids (ICS). The second most common treatment varied according to age group, with short-acting beta(2)-agonist (SBA) preferred for infants, montelukast or short-acting beta(2)-agonist for pre-schoolers and combination therapy (ICS + long action beta(2)-agonist) for school-aged children. Objective monitoring of lung function with peak flow or spirometry, was used by 40% of GPs and 59% of paediatricians. Acute asthma was primarily managed with inhaled salbutamol and oral corticosteroids. There were few differences in treatment choice between GPs and paediatricians. Many GPs indicated that they did not treat asthma in infants without specialist consultation.

CONCLUSIONS

These data show good compliance by the minority of GPs responding to the survey and by paediatricians practising in Western Australia with current Australian asthma management guidelines. Major differences in treatment preferences between the groups were not detected.
