Development of a core drug list towards improving prescribing education and reducing errors in the UK.

Aim: To develop a core list of 100 commonly prescribed drugs to support prescribing education.

Methods: A retrospective analysis of prescribing data from primary care in England (2006 and 2008) and from two London Teaching Hospitals (2007 and 2009) was performed. A survey of prescribing by foundation year 1 (FY1) doctors in 39 NHS Trusts across London was carried out.
