The responsibility for prescribing rests with the doctor or healthcare professional who has clinical responsibility for a particular aspect of the patient’s care. Where, for instance, an NHS doctor refers a patient (privately or otherwise) to a consultant for advice but, when appropriate, retains clinical responsibility, he/she should issue the necessary prescriptions at NHS expense, provided it is considered normal clinical practice and within local guidelines and formularies.
"A patient whose private consultant has recommended treatment with a medication normally available as part of the NHS commissioned care in the patient’s clinical circumstances can ask his or her NHS GP, consultant or an appropriate health care professional to prescribe the treatment as long as:
• the GP / consultant/health care professional considers it to be medically appropriate in the exercise of his or her clinical discretion;
• the drug is listed on the ICB’s formulary or the drug is normally funded by the ICB; and
• the GP / consultant/health care professional is willing to accept clinical responsibility for prescribing the medication.
There may be cases where a patient’s private clinician/health care professional has recommended treatment with a medication which is specialised in nature and the patient’s GP is not prepared to accept clinical responsibility for the prescribing decision recommended by another clinician. If the GP does not feel able to accept clinical responsibility for the medication, the GP should consider whether to offer a referral to an NHS clinician who can consider whether to prescribe the medication for the patient as part of NHS funded treatment. In all cases there should be proper communication between the consultant/health care professional and the GP about the diagnosis or other reason for the proposed plan of management, including any proposed medication.
Medication recommended by private clinicians may be more expensive than the medication options prescribed for the same clinical situation as part of NHS treatment. In such circumstances, local prescribing advice from the ICB should be followed by the NHS GP/health care professional without being affected by the privately recommended medication. This advice should be explained to the patient who will retain the option of purchasing the more expensive drug via the private clinician."
