Haemophilia and Thrombosis referrals

Use e-Referral for all routine and urgent patients.

Directly Bookable Service for Haemophilia and Thrombosis

The GP surgery will generate an appointment referral request with appropriate priority (urgent or routine) for the service on e-Referral and UBRN in the usual way.

An electronic proforma or appropriate letter needs to be attached to the e-Referral system by the surgery within 48 hours for a routine or urgent appointment.

In the case that the Trust cannot provide an immediate appointment, 'Defer to Provider' can be selected and Trust processes will be in place to contact the patient within 48 hours for an urgent or routine appointment.

18WW clock will start on the date the GP or patient makes the appointment booking.

GPs should check their patients have appointments on their e-Referral worklist. This applies to all appointment requests made through e-Referral.

For further information please visit 'e-Referral':

Treatment pathways for bleeding disorders

Shared care

The exception is shared care clinic arrangements for adult patients with inherited moderate and mild bleeding diseases in Northampton.

However, once well enough for discharge, they can be referred to the DVT Clinic for follow-up.
