Three-Part Question:
In children with asthma [patient] do parent-initiated oral corticosteroids (OCS) [intervention] reduce the likelihood of hospital presentation or admission [outcome].
Clinical Scenario:
You are a paediatric specialist registrar giving discharge advice to the parents of a 7 year old girl who is recovering from an episode of acute asthma. She has a frequent episodic pattern of asthma and normally receives 100mcg of fluticasone morning and night. Her parents ask you if they should wait to see a doctor before commencing her on prednisolone if she has another 'asthma attack'?

Author Commentary:
Oral corticosteroids (OCS) commenced following physician review are effective in the treatment of acute asthma in children [Rowe, 2003], and it would seem logical that parent-initiated OCS may be an effective strategy. However, it is important to recognise two important limitations of this theory. First, only a minority of episodes of acute wheeze that occur in the community result in an emergency department review [Robertson, 2003], and it is likely that many episodes of acute wheeze that occur in the community are too minor to justify OCS therapy. Second, parent-initiated therapy relies on the ability of the parent to make an accurate assessment of their child's clinical status, and there are a number of studies which have demonstrated that parents have some difficulty in making this assessment [Levy, 2004. Lowe, 2004]. It is also important to recognise that parent-initiated treatment with OCS is likely to result in more frequent administration of OCS. This may have important implications for growth, osteoporosis, and adrenal suppression (although the existing data is reassuring [Ducharme, 2003]).
The limited amount of published data available do not show a benefit from parent-initiated OCS in terms of hospital admissions, unscheduled medical reviews, symptom scores, or the use of bronchodilators in children treated with parent-initiated prednisolone compared with placebo. Moreover, there is evidence from at least one trial [Grant, 1995], that such an intervention actually increases medical visits, at least in pre-school age children - this may be related to OCS-induced behavioral and emotional changes [Kayani, 2002].
There are a number of limitations in the existing literature. The included studies lack sufficient power to confidently exclude a benefit from parent-initiated OCS. The disease severity of the trial participants in the included studies is difficult to quantify, and the majority of data relate to preschool aged children only. It is also difficult to know if parents in the included studies commenced study medication for an appropriate indication. Therefore, it is possible that the effectiveness of parent-initiated OCS have been diluted by the inclusion of (1) data from children with mild disease, (2) data from minor episodes of wheeze, and (3) data from illnesses misdiagnosed by the parents.
In summary, OCS have a clearly defined role in the management of acute asthma in the hospital setting, and it is likely that parent-initiated OCS are appropriate for some children with severe disease. However, widespread use of parent-initiated OCS cannot be recommended until the benefits and harms can be clarified further.

Bottom Line:
(1) Oral corticosteroids are effective in the treatment of acute asthma in the emergency department (Grade A).
(2) Parent-initiated OCS may be appropriate for some children with severe asthma, however, there is insufficient evidence to recommend widespread use of parent-initiated OCS in children with asthma (Grade D).
