Powys Teaching Health Board

Powys Teaching Health Board has agreed a ‘Traffic Light’ classification for drugs that may be prescribed for Powys patients. The definitions of the classifications are below.
GREEN First line medicines which may be freely prescribed by all prescribers within local or national recommendations.
BLUE Second line medicines which may be freely prescribed by all prescribers within local or national recommendations.
AMBER Medicines which should only be initiated/recommended by specialists but which may then be passed to primary care prescribers for prescribing
AMBER SHARED CARE Drugs initiated by hospital specialist, but where continuing treatment by Primary Care Prescribers may be appropriate under a shared care arrangement. Shared care guidelines are available or are being developed for most of these. If no shared care guideline is available, the hospital specialist should provide the Primary Care Prescriber with sufficient information and support to allow treatment to be continued and managed safely in primary care.
RED Drugs for hospital or specialist use only. The responsibility for initiation and monitoring treatment should rest with an appropriate hospital clinician and the drug should be supplied through the hospital throughout the duration of treatment. Primary Care Prescribers should not be asked to prescribe.
BLACK Not recommended for prescribing in Primary or Secondary Care except under exceptional circumstances.
  Cost = not recommended for cost reasons
  Clinical = not recommended for clinical reasons
GREY Funding request required via the Individual Patient Funding Request Panel
PINK Multiple categories within the same drug group
This list should be reviewed at each Primary Care Drug and Therapeutics Meeting to take into account new drugs and changes in clinical practice.
