Background/Aims 

The range of approved immunosuppressive and immunomodulatory (IM) agents has grown considerably with an increasing list of indications across paediatric specialties. At present, there is limited evidence supporting best practice for prescribing and monitoring of IM agents in children and young people (CYP). We present a staged service development project exploring cross-specialty prescribing and monitoring of IM agents at a tertiary children’s hospital (Great North Children’s Hospital, GNCH) and data sharing with local hospitals across northeast England.

Methods 

In Phase 1, we searched pharmacy databases and surveyed specialty teams in GNCH to identify clinicians regularly prescribing IM agents to CYP over a twelve-month period. Phase 2 was a cross-specialty retrospective case-notes review of prescribing, monitoring and infection surveillance in a representative sample of CYP on IM agents. Phase 3 explored information sharing with six other hospitals in the region and acute presentations to these sites involving CYP on IM agents.

Results 

Phase 1 identified 9 paediatric and 2 adult specialties prescribing IM agents to 416 CYP. 32 discrete IM therapies were prescribed with significant between-specialty overlap in drugs prescribed but a wide range of prescribing and monitoring practices. Phase 2 assessed 77 CYP on IM agents in detail - 57% were prescribed &gt;1 IM agent, 100% had FBC measured at least once (range once only to weekly), 18% developed lymphopenia at least once and 40% were prescribed prophylactic antibiotics. Previous varicella exposure had been assessed in 70%. Phase 3 data are summarised in Table 1.

Conclusion 

IM agents are central to modern paediatric clinical care across a wide range of diseases. This staged project identified significant variation in IM prescribing and monitoring practice between specialties at GNCH. Communication between specialty and local teams is inadequate. Particular areas of concern include limited diagnostic, blood monitoring and medication information sharing and limited local information governing management of intercurrent illness and vaccination. Although different disease processes can necessitate different advice and prescribing practices, sharing examples of good practice will minimise unnecessary variation. We propose the development of a regional immunosuppression working group to improve quality and safety across our region.
