18 weeks inter-provider transfers


The Department of Health mandated the use of a minimum data set for inter-provider transfers from 1 January 2008. The pathway data contained within this data is essential in order for receiving organisations to accurately monitor and report patient waiting times.

Inter-provider transfers to Guy's and St Thomas'

Referrals from other hospitals to Guy's and St Thomas' must include a completed inter-provider minimum data set (MDS) or ensure that one is sent within 48 hours of referring a patient.

Download the inter-provider minimum data set (PDF 140Kb).

All inter-provider transfer minimum data sets must be sent to the Referral Management Service at the address below:

18 Week Inter-provider Team

Mary Sheridan House

or by email to: 

If an MDS is not received within 48 hours of a referral letter, we will contact your trust to request a fully completed MDS.
