<qa>  What is the purpose of the Cochrane Database?Telephone medical advice in general practice is expanding. The Cochrane Database concludes in 2008 that there is not enough data about its use regarding out-of-hours general practitioners workload, emergency department visits, cost, safety and patient satisfaction. The aim of this study is to assess the effectiveness of telephone medical advice given by a general practitioner in a call centre for patient presenting isolated fever or gastroenteritis symptoms.
