Over a 15 month period, all the scripts written by doctors in the Episkopi Garrison Medical Centre, Cyprus, were analysed. A formulary was produced by using the most popular items in that 15 month period and tested in a one month trial period. The idea was to find a practical and efficient method of producing a 'basic' formulary to which items could be added or removed after discussion with colleagues.
