Although it is possible within the legislation to use a PGD to initiate treatment for long term conditions, it is not recommended. Long term conditions should be managed by healthcare professionals prescribing for individual patients on a one-to-one basis.
There may be occasions, however, when a healthcare professional e.g. in an Urgent Care Centre, treats someone under a PGD for symptoms arising from a chronic disease e.g administration of salbutamol in acute asthma. This highlights the importance of including clear instructions in the PGD on referral of patients (in this case, to their usual prescriber or the health professional responsible for their longer-term care) and any other follow-up action required.
