MHRA undertook a survey of companies who undertake user testing on 
behalf of marketing authorisation holders. The survey was carried out 
between 20 December 2006 and 11 January 2007 and a summary report is 
available on our website. A number of common themes emerged from the 
responses. As a result further guidance for MA holders and others who draw 
up patient information leaflets has been prepared to help achieve quality 
improvements and success in user testing.
