Shared Care Protocol for the Management of Inflammatory Arthritis & Connective Tissue Disease for Adult services, over 16
1.0 INTRODUCTION
The use of disease modifying antirheumatic drugs (DMARDs) in treating early and established stages of Inflammatory Arthritis (IA) and in managing Connective Tissue diseases (CTD) is accepted practice. General Practitioners (GPs) are becoming more involved in active management of these conditions with the recognition that patients should be referred early for specialist advice and initiation of disease modifying drugs.
This protocol sets out guidelines for treatment of CTD & IA and delineated responsibilities when care is to be shared between Primary Care and Rheumatology Specialist services.
Shared Care Protocols are intended to provide clear guidance to General Practitioners (GPs) and hospital prescribers regarding the procedures to be adopted when clinical (and therefore prescribing and financial) responsibility for a patient’s treatment with a shared-care disease is transferred from secondary to primary care.
GPs, as independent contractors, have the right to decline to take clinical and prescribing responsibilities for a patient on their medical list who is being treated elsewhere. However the reason for this action must be documented. In the view of the Doncaster & Bassetlaw APC, it would be the exception for a GP to refuse to take clinical and prescribing responsibilities for an individual drug, where shared care guidelines for that drug have become common practice and where shared care guidelines include adequate support, education, and information as approved by the Doncaster & Bassetlaw APC.
If a specialist asks a GP to prescribe these drugs in relation to this disease, the GP should reply to this request as soon as practicable. The doctor who prescribes the medication legally assumes clinical responsibility for the drug and the consequence of its use.
The Doncaster & Bassetlaw Hospitals NHS Foundation Trust is a multi-site trust covering 2 PCT areas (Doncaster and Bassetlaw), with the Rheumatology department split over the two main hospitals. The process of shared care traditionally occurs for the DRI Rheumatology patients treated at Doncaster Royal

Infirmary. and for Bassetlaw patients primary care normally monitor DMARDs. The reason for the difference dates back before the two hospitals merged as one trust. This protocol should allow GPs to undertake either method.
While this document looks to medications used in the treatment of CT & IA diseases, not all drugs will be covered by a shared care protocol for prescribing.

2.1 RheMOS System General
Doncaster Rheumatology unit use a monitoring system aided by a nationally recognised program called RheMOS. This essentially is a software package that can assess trends in a patient’s blood test parameters. It then highlights when a patient deviates outside set parameters and has not had a blood test according to their drugs’ protocol. This is then actioned by the Rheumatology team as appropriate depending on the clinical situation. Patients are sent the regular blood forms by the support staff in the post, which have a bar code on which highlights to the Trust’s PAS system that it is a RheMOS patient. Recently, the Trust has gone paperless for RheMOS blood results as they were not needed. The forms are sent out each time the patient reaches the end of their group of forms and then ring in on a dedicated phone line extension, which each patient is given. This system also allows for tracking when patients do not attend for blood tests and the departments own protocol for this is followed.
2.2 RheMOS DNA Protocol
If patents DNA blood tests, they are sent a reminder letter as soon as is practicable, asking them to either attend for the blood test or contact on nurses help line if there are problems. They are warned in the letter that it is dangerous to continue the drug unmonitored and if they fail to have the blood test performed treatment might need to be stopped. If the patient fails following this to have a blood test performed or contact the department then a letter is sent to the patient, their GP and whoever is prescribing the DMARD (ie hospital pharmacy) asking them to stop the treatment and that if they continue to take the DMARD after this then that is at their own risk. Contact numbers are again provided on the letter.
2.3 Pregnancy and Breast Feeding
When a patient is prescribed a DMARD there are significant issues regarding pregnancy and family planning posed by the potency and potential teratogenic potential of these drugs. The decision about when and what drugs should be stopped is a decision that needs to be taken in secondary care. The decisions potentially affect both male and female patients depending on the drugs being used. Please see Appendix for specific advice on each drug. Overall the principle is to use the least level of treatment to control the disease but in certain conditions such as SLE, stopping some DMARD therapies has been shown to increase risk of flare and consequent risk to mother and baby. Please refer to Appendix 1.
Breastfeeding should not be advised if a mother is on any DMARD, even those felt to be safe during pregnancy, as small amounts are excreted in the breast milk.

2.4 Chicken Pox
Immunosuppressd Varicella Zoster Virus (VZV) naïve patients have a significant risk of disseminated infection if exposed or contract infection. Therefore, information is passed to all patients in secondary care on DMARD / steroid therapy as what to do if they are exposed or contract chicken pox.
Exposed to VZV and within incubation period o Previous history of chicken pox Only treat if develop active infection; usually aciclovir o No history of chicken pox . Urgent assessment of VZV antibodies . If antibody status negative: treatment with pooled immunoglobulin . If antibody status positive: only treat with acyclovir if develop infection Active VZV Infection o Previous history of infection – treat with acyclovir o No history of chicken pox . Urgent assessment of antibodies . Detailed clinical assessment and anti-viral treatment dependent on clinical presentation
2.5 Immunizations
No live vaccine should be given to any immunosuppressed patient. All patients on methotrexate, azathioprine, ciclosporin, lefluonamide, mycophenolate and cyclophosphamide should be offered annual flu vaccination and the one off pneumococcal vaccine unless contraindicated.

4.0 SHARED CARE ARRANGEMENTS
Once a stable medication regime has been established (usually 3 months), physical monitoring and prescribing of amber category drugs can be transferred to primary care with agreement.
4.1 Aspects of care for which Secondary Care Team is responsible
Diagnosis and assessment Initiation and stabilisation of drug therapy, usually but not exceptionally, a period of 3 months. Patient/ family education Ensure patient is fully informed of potential benefits and side effects of treatment Ensure patient’s guardian/carer is fully informed of the treatment. Provide a comprehensive treatment package in addition to medications including appropriate information/monitoring sheet(s) Ensure that shared care arrangements are in place before transfer of treatment . That the patient/carer is clear what is being monitored and by whom . That the patient knows what significant adverse effects/events to report urgently and to whom they should report (specialist or GP) Any dose changes once the patient is established on treatment will be conveyed in writing to the GP for the GP to prescribe. Extra monitoring needed for dose changes will be organised by Rheumatology team and conveyed to patient Monitor side effects of medication via routine out-patient visits or nurse telephone help line. Report adverse events to the CSM Monitor patient’s response to treatment If patients are being monitored using RheMOS system, patients will be sent blood forms and have the results analysed using the already established system (see section 2.1) If blood abnormalities occur secondary to DMARD picked up using RheMOS, action appropriate to the abnormality will be organised via the Rheumatology team. If patients DNA their blood test monitoring as picked up on RheMOS, the Rheumatology units protocol will followed (see appendix)
4.2 Aspects of care for which Primary Care Team is responsible
Ensure that shared care arrangements are in place before transfer of treatment . That the patient/carer is clear what is being monitored and by whom . That the patient knows what significant adverse effects/events to report urgently and to whom they should report (specialist or GP)
11 This Document will be reviewed in the light of new or emerging evidence or by October 2014 Doncaster & Bassetlaw Area Prescribing Committee October 2009 V2.0
When the specialist initiates treatment, reply to the request for shared care as soon as practicable Confirm that proposed therapy is not contra-indicated because of concurrent therapy for other conditions the patient may be suffering from e.g. check drug-contraindications and drug-interactions. Contact specialist team if possible interactions found and discuss with rheumatologist Confirm the specialists have provided the patient/carer with appropriate information sheet(s) for monitoring and/or to alert other clinical staff to the treatment they are receiving. If appropriate information has not been provided by the specialist, the GP must ensure the information is provided Ensure patient’s guardian/carer is fully informed of the treatment Monitor treatment as stated in the shared care protocol Amend prescription as per requests from secondary care for dose changes in patients on established treatment Confirm with specialist which changes in these or other parameters should trigger urgent referral back to the specialist Seek specialist advice promptly as advised in the shared care protocol or if signs/symptoms of changes occur consistent with DMARD adverse event Report adverse events to the CSM If the drug has a black triangle status or is unlicensed, all events should be reported even if casual relationship is not known or if the adverse event is already known about Report adverse events to the consultant sharing the care of the patient Stop treatment on advice of specialist, or immediately if intolerable side effects occur provided that it is safer to do so than to continue this therapy
4.3 Patient (or Carer’s) Responsibilities
Discuss potential benefits and side effects of treatment with the specialist and GP. Identify whether they have a clear picture of these from the specialist and to raise any outstanding queries Check that where possible the specialists have provided a patient-held record or information sheet for monitoring and/or to alert other clinical staff to the treatment they are receiving Share any concerns they have in relation to treatment with the medicine Report any adverse effects to their specialist or GP whilst taking the medicine Report to the specialist or GP if they do not have a clear understanding of their treatment Participate in the monitoring of therapy and the assessment of outcomes, to assist health professionals to provide safe, appropriate treatment

5.0 PROCEDURE FOR ADOPTING SHARED CARE
5.1 General Procedure:
The specialist will send to the GP a diagnostic assessment report, a copy of the shared care protocol and a shared care referral specifying who is responsible for monitoring. Both the specialist and GP should sign the proforma with a record kept in the GP and specialist records. Full details will be given of the prescribing regime (brand, form, strength and dose of medication) and follow-up plan.
The patient will be asked to make arrangements with their GP for continued supply.
