The next step is to seek relevant evidence that will help you answer the question.

Sources are:

1. Traditional methods (textbooks, journals).
2. Ask an expert. (answer quality will vary)
3. Summarised clinical evidence (BestBets).
4. Electronic bibliographic databases(Cochrane Library databases, PUBMED, MEDLINE, EMBASE, and CINAHL).

• Use Boolean operators "AND" and "OR"
• Example:

1. Viral bronchiolitis
2. Corticosteroids OR steroids OR glucocorticoids OR prednisolone OR dexamethasone
3. Clinical score OR hospital stay
4. (1) AND (2) AND (3).
