Intervensjon / Behandling |
|---|---|
|
Intensive structured education group
Regular outpatient visit in every 3 months to these patients.
The glucose control and diabetes complication screening will be evaluated in visit.
Patients will also be evaluated by specialized psychologists, dietitians and therapists.
Diabetes self-management education will be regularly exposed to patients
|
The structured education is based on a regular outpatients visit.It is an education that integrated several diabetes related subjects,which mainly aimed at T1D self-management.
|
|
Conventional education group
Outpatients visit to endocrinologists when necessary in a conventional way.

Tidsramme |
|---|---|---|
|
Effects of structured education on β-cell endocrine function progression of T1D patients.
Tidsramme: Baseline and every three months afterwards.
|
The natural progression of patients' β-cell endocrine functions was assessed by fasting C-peptide (FCP) and postprandial C-peptide (PCP) at each visit. FCP and PCP levels were measured at initial recruitment and every three months after that. The decay rate of β-cell endocrine function of patients in the two groups were compared. Serum C-peptide levels were measured by a chemiluminescence method using a commercial available kit (Adiva Centaur System, Siemens, Germany). |
Baseline and every three months afterwards.
