Study summary

For last decade, the innovation of mobile health platform has brought new opportunities for disease management. Previous studies have shown that health management programs based on mobile platforms for patients with diabetes can improve patients' glucose control, self-management ability and quality of life. Type 1 diabetes mellitus (T1DM) due to its characteristics needs long-term linkage care throughout the lifespan cycle of patients. Therefore, this study intends to construct a prospective and open T1DM cohort based on mobile application and platform, to deliver home-community-hospital joint management for patients, and to provide follow-up online or offline every 3 months lasting for 10 years. Mainly, the objective of this study is to observe the blood glucose control outcome of T1DM patients. Secondly, the control of comprehensive metabolic indicators such as blood pressure and blood lipid, occurrence and progression of acute and chronic complications, and psychosocial status were included as well, expecting to provide scientific evidence for continuously improving the quality of T1DM management.

What researchers measure

Primary outcomes

  1. HbA1c

    HbA1c is one of the indicators that reflects the level of blood glucose control overall. Blood sample will be required and tested.

    Time frame: Outcome evaluation at 10 years.

  2. Time in range (TIR)

    TIR is one of the indicators that reflects the level of blood glucose control from the point of view of target time. Continuous glucose monitoring (CGM) devices will be used.

    Time frame: Outcome evaluation at 10 years.

  3. Incidence of hypoglycemia

    Incidence of hypoglycemia is one of the indicators that reflects the level of blood glucose control. Hypoglycemia is defined as blood glucose lower than 3.9mmol/L with or without symptoms. Incidence of hypoglycemia is occurence times per month according to patients self-reported.

    Time frame: Outcome evaluation at 10 years.

Secondary outcomes

  1. Comprehensive metabolic control

    Blood pressure is one of the control level comprehensive metabolic indicators, including systolic blood pressure (SBP) and diastolic blood pressure (DBP).

    Time frame: Outcome evaluation at 10 years.

  2. Comprehensive metabolic control

    Blood lipid is one of the control level of comprehensive metabolic indicators, including total cholesterol (TC), total triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C).

    Time frame: Outcome evaluation at 10 years.

  3. Occurrence of Diabetes-related complications.

    To observe and analyze occurrence of diabetes-related acute and chronic complications. Acute complications of diabetes include diabetic ketoacidosis (DKA), hypoglycemia and Hyperglycemic Hyperosmolar Syndrome (HHS). Chronic complications of diabetes including retinopathy, neuropathy nephropathy and lower extremity amputations (LEA). Other diabetes-related complications include cardiovascular disease, heart failure, stroke and death.

    Time frame: Outcome evaluation at 10 years.

  4. Progression of Diabetes-related complications.

    To observe and analyze progression of diabetes-related acute and chronic complications. Acute complications of diabetes include diabetic ketoacidosis (DKA), hypoglycemia and Hyperglycemic Hyperosmolar Syndrome (HHS). Chronic complications of diabetes including retinopathy, neuropathy nephropathy and lower extremity amputations (LEA). Other diabetes-related complications include cardiovascular disease, heart failure, stroke and death.

    Time frame: Outcome evaluation at 10 years.

  5. Anxiety condition.

    Anxiety condition is one of the psychosocial status indicators, and Self-Rating Anxiety Scale (SAS) will be used to assess anxiety level. The score ranges from 20 to 100, and higher score indicates more prone to anxiety.

    Time frame: Outcome evaluation at 10 years.

  6. Anxiety condition.

    Anxiety condition is one of the psychosocial status indicators. Generalized Anxiety Disorder 7-Item Scale (GAD-7 scale) will be used to assess anxiety symptoms. The score ranges from 0 to 7, and higher score indicates more anxiety symptoms.

    Time frame: Outcome evaluation at 10 years.

  7. Depression condition.

    Depression condition is one of the psychosocial status indicators, and Self-Rating Depression Scale (SDS) will be used to assess depression level. The level of depression is measured by depression severity index. The index ranges from 0.25 to 1.0, with higher scores associated with greater depression.

    Time frame: Outcome evaluation at 10 years.

  8. Depression condition.

    Depression condition is one of the psychosocial status indicators, and Patient Health Questionnaire-9 (PHQ-9) will be used to assess depression level. The score ranges from 0 to 27. A higher score indicates a higher degree of depression.

    Time frame: Outcome evaluation at 10 years.

  9. Depression condition.

    Depression condition is one of the psychosocial status indicators, and Problem Areas in Diabetes-Short form (PAID-5) will be used to evaluate the diabetes related emotional distress, which is strongly association with depression. A score ≥40 indicates high diabetes-related distress.

    Time frame: Outcome evaluation at 10 years.

  10. Life quality.

    Life quality is one of the psychosocial status indicators, and specific scales as World Health Organization-5 well-being index (WHO-5) will be used to assess this factor. A score \<50 indicates poor psychological well-being.

    Time frame: Outcome evaluation at 10 years.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Jun 2022; primary completion for Jan 2032, 115 months later.

Of 239 non-industry observational studies under Diabetes Mellitus, Type 1, half reached primary completion within 30 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 78. This study's planned 115 months is above that.

Counting every sponsor, half of 288 studies reached it within 27 months; a quarter within 12 and three quarters within 69.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 1, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
