Requirements for ideal YPC services Transition services rather than transfer clinic MDT (educator, dietician, specialist) Database (local, regional, links with primary care) One stop clinic (annual care cycle including retinal screening) Emphasis on self management (structured educational programmes) Pump services (CSII + CGMS + intense education) Effective protocols and policies for dealing with DNAs Flexible clinic times Tamworth workshop 30/11/09

Principles Encouragement rather punishment! Communicate in the preferred way (text, etc) Post clinic discussions Open access clinics Continuity of care Long term specialist follow-up in view of complications Tamworth workshop 30/11/09
