The aim of the formulary

The main aim of this BSW Joint Formulary is to promote safe, evidence-based, cost-effective prescribing across primary and secondary care. It is not intended to cover all prescribing, but should provide appropriate treatment for the vast majority of patients. The Joint Formulary provides a selective list of medicines which will lead to a greater familiarity with a limited range of medicines, helping to reduce prescribing errors and promote a seamless approach to prescribing.

The BSW Joint Formulary has arisen as an amalgamation of three existing formularies

  • BCAP Bath Clinical Area Partnership Joint Formulary
  • 3Ts Formulary Great Western Hospital Swindon 
  • Microguide Formulary Salisbury Foundation Trust

A number of ‘differences’ in formulary options and traffic light statuses have yet to be agreed to a single decision hence multiple traffic lights may be shown. 

A definition of the traffic light status are listed below and at the bottom of each page.
