Clinical Guidelines for Operations (CGOs)

Guidance on best medical practice for military and civilian clinicians deployed on operations.



Joint Service Publication 999 is the policy which provides deployed medical experts with guidance as to best medical practice. It is not intended to be an all-compassing textbook of ‘Military medicine and surgery’. Neither should the guidelines be viewed as mandatory practice, clinical judgement must be used at all times.

However, Clinical Guidelines for Operations (CGOs) acts as a guide and aide-memoire for clinicians in the field encountering conditions as they do not often see in their UK employment or the management of which is changed by the deployed environment. CGOs also provide an audit framework against which treatment can be measured.

JSP 999 has replaced JDP 4-03.1: clinical guidelines for operations.
