Introduction

Introduction

  • Due to the potentially serious side-effects that Disease Modifying Anti-Rheumatic Drugs (DMARDs) can occasionally cause, regular blood monitoring is necessary.

  • In Derbyshire DMARDs are classified as AMBER drugs i.e. considered suitable for GP prescribing following specialist initiation of therapy and patient stabilisation, with specific long term monitoring for toxicity needing ongoing specialist support.


Dmard shared care guidelines

  • The concept of drugs that GPs would not routinely initiate and therefore would not normally be familiar with is encompassed in Dept. of Health EL(91)127 “Responsibility for prescribing between Hospitals and GPs”.


Referral criteria

Referral Criteria

  • Shared Care is only appropriate if it provides the optimum solution for the patient.

  • Prescribing responsibility will only be transferred when it is agreed by the consultant and the patient’s GP that the patient’s condition is stable or predictable.


Referral criteria1

Referral Criteria

  • Safe prescribing must be accompanied by effective monitoring

  • Patients will only be referred to the GP once the GP has agreed in each individual case.

  • Once stable the patient will be given a supply of Methotrexate sufficient for 4 weeks maintenance therapy.


Three areas of responsibility
