The scientific use of basal insulin is of great help to individuals and the government. However, there are few studies to investigate the real world use, effect, safety and influence factors of basal insulin in China. This study is to evaluate the use of first basal insulin in China patients with type 2 diabetes with inadequate glycemic control on oral antidiabetic agents (OADs) from the naturalistic clinical practice.


Study Type: Observational [Patient Registry]
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Target Follow-Up Duration: 6 Months
Official Title: A Prospective, Observational Registry Study Focusing on the Real World Use, Effectiveness and Safety of Initial Basal Insulin Regimen in Type 2 Diabetic Patients Uncontrolled by Oral Antidiabetic Drugs in China

Primary Outcome Measures:
  • To Assess the Change in HbA1c During the 6 Months Follow-up. [ Time Frame: Baseline and 6 months ]
    • Change of HbA1c from baseline to the end-point (6 month).

  • the Change of Hypoglycemia During Follow-up. [ Time Frame: baseline and 6 months ]
    •The rate of hypoglycemia at baseline, 3 months (visit 2) and 6 months (visit 3)

Secondary Outcome Measures:
  • the FPG Change From Visit 1 to Visit 3 [ Time Frame: baseline and 6 months ]
    the FPG change = the FPG level at visit 1- the FPG level at visit 3

  • the FPG Control Rate at Visit 3 [ Time Frame: 6 months ]
    the percentage of patients who had the FPG level <7.0 mmol/L at visit 3

  • Overall Weight Gain From Visit 1 to Visit 3 [ Time Frame: baseline and 6 months ]
    the weight gain= the mean weight at visit1 - the mean weight at visit 3

Enrollment: 19894
Study Start Date: December 2011
Study Completion Date: June 2014
Primary Completion Date: June 2014 (Final data collection date for primary outcome measure)
Detailed Description:

This is a 6-month multicentre, observational, prospective, registry study. About 200 hospitals from different parts of China will take part in this study, and about 20,000 patients with type 2 diabetes mellitus (T2DM) who are inadequately controlled with OADs and willing to accept basal insulin (BI) treatment will be consecutively enrolled during a 12 months period.

The study participants will include at baseline (0 month), 3 month and end point (6 month) to collect the study information. The project will probably last for about 18 months.


Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Patients meet the following criteria, either from in-patient or out-patient department, will have chance to be enrolled in this study.

Inclusion Criteria:

  • Taking OADs before inclusion
  • Recently tested HbA1c >=7% at the same site within 3 months
  • Being suggested by physician to start basal insulin (BI) treatment
  • Willing to start and having been prescribed BI treatment
  • Willing to join the registry study and sign the informed consent

Exclusion Criteria:

  • Diagnosed with type 1 diabetes
  • Received any type of insulin in the last 2 years (except for the intermittent use of insulin of less than 1 month each time)
  • With any severe health problem, or any other situation judged by the investigator, that is difficult for the 6 months follow-up
  • Current or planned pregnant, lactating women
  • Involved in other clinical trial simultaneously or at most 1 month before
