Detailed Description
Aim: This study constructs a general practitioners and diabetes specialists co-management model for patients with type 2 diabetes in the community based on the integration of prevention and treatment strategies. Also, the effectiveness of the model will be evaluated by a parallel randomized controlled trial design to provide theoretical support and empirical evidence for the development of a comprehensive management strategy for patients with type 2 diabetes.
Hypothesis: Compared to the control group, the intervention group receiving co-management by general practitioners and diabetes specialists has a greater improvement in HbA1c, fasting glucose, blood pressure, lipids, BMI, diabetes self-management ability, depression symptoms, diabetes distress, and diabetes complications-related indicators.
Recruiting: This study will recruit patients with type 2 diabetes who have established electronic health records in the community healthcare centers affiliated with the Baoan Central Hospital of Shenzhen. General practitioners at the community healthcare centers screen patients with type 2 diabetes under their care who are eligible for the study based on the inclusion and exclusion criteria. Following face-to-face communication, general practitioners explain the study objectives and procedures to patients and obtain their informed consent.
Before the start of the study, unified training will be conducted for the general practitioners involved in the recruitment so that they can clarify the inclusion and exclusion criteria, screening methods, and precautions regarding the study objects.
Randomization Procedure: Members of the research team served as the grouping scheme controllers of the randomization center. The Proc plan procedure of SAS 9.4 statistical software was used to generate random number sequences and grouping schemes according to a 1:1 assignment. For the patients with type 2 diabetes who met the inclusion and exclusion criteria, general practitioners contacted randomization center staff members by telephone according to the patients' order of arriving at the community healthcare center and informed them of the patient's name and ID number. Then the randomization center staff recorded patient information, numbered the patients, and divided them into intervention group or control group according to the previously generated random number table. Finally, the randomization center staff informed patients' general practitioners of their grouping results.
Study design: The study includes three phases: baseline, intervention, and follow-up. All participants will be divided into intervention group and control group after completing the baseline survey. The implementation phase of the intervention will last 12 months. Patients in the intervention group will have daily blood glucose monitoring with a smart home blood glucose meter, as well as glycated hemoglobin testing at a community health center every three months. Each patient will be assigned a dedicated general practitioner to track the patient's blood glucose monitoring results. Based on the remote monitoring of blood glucose and HbA1c tests, general practitioners and specialists will jointly carry out management measures including health education, medication adjustment, outpatient consultation, referral, and case discussion for participants.
The control group will be routinely treated and followed up by general practitioners according to Chinese clinical guidelines and national norms for basic public health services.
Data collection and Management: Baseline and follow-up data were collected using questionnaires and physical examination record forms. The collected data was entered into Epidata software and imported into Statistical Analysis System(SAS) 9.4 for analysis. After the end of the experiment, the data will be stored in the database of our research group for a long time.

Outcome Measures
Primary Outcome Measures
- HbA1c change [Baseline, 6, 12, and 24 months]
The change of HbA1c during the study. The level of HbA1c in blood measured in %.
Secondary Outcome Measures
- Fasting Plasma Glucose [Baseline, 6, 12, and 24 months]
The change of HbA1c during the study.
- Total cholesterol [Baseline, 6, 12, and 24 months]
The change of total cholesterol during the study.
- Triglycerides [Baseline, 6, 12, and 24 months]
The change of total triglycerides during the study.
- LDL-C [Baseline, 6, 12, and 24 months]
The change of LDL-C during the study.
- HDL-C [Baseline, 6, 12, and 24 months]
The change of LDL-C during the study.
- Blood pressure [Baseline, 6, 12, and 24 months]
The change of blood pressure during the study.
- Body Mass Index (BMI) [Baseline, 6, 12, and 24 months]
The change of BMI during the study.
- Serum creatinine [Baseline, 6, 12, and 24 months]
Clinically detecting serum creatinine is one of the main methods to understand renal function, and it is an important indicator of kidney function, and an elevated serum creatinine means the damage of kidney function.
- Blood urea nitrogen [Baseline, 6, 12, and 24 months]
Blood urea nitrogen is clinically used as important acute kidney injury (AKI) biomarker.
- Urinary microalbumin [Baseline, 6, 12, and 24 months]
Urinary microalbumin is predictor of progressive kidney diseases.
- Incidence of diabetic retinopathy [Baseline, 6, 12, and 24 months]
Incidence of diabetic retinopathy
- Macrovascular Complications [Baseline, 6, 12, and 24 months]
Incidence of macrovascular complications (carotid, cardiovascular).
- Diabetes self-care activities [Baseline, 6, 12, and 24 months]
Diabetes self-care activities will be measured by the Summary of Diabetes Self-Care Activities (SDSCA) scale. The SDSCA scale measures the frequency of performing diabetes self-care activities, including diet, exercise, blood glucose testing, foot care, and tobacco use over the past 7 days. SDSCA comprises of 11 items and each item's response is rated on 7 point scale ranging from '0' to '7' . A higher score would be the frequency of performing self-care activities.
- Diabetes distress [Baseline, 6, 12, and 24 months]
Diabetes distress scores will be measured by the Problem Areas In Diabetes (PAID). The scale ranges from a minimum of 0 (not a problem) to a maximum score of 4 (serious problem). The sum of the five questions provides the participant's score with a score range of minimum score of 0 to a maximum score of 20. A total score of greater than or equal to 8 indicates possible diabetes related emotional distress, with a higher score indicating more significant distress.
- Depressive symptoms [Baseline, 6, 12, and 24 months]
Depressive symptoms will be assessed by the Patient Health Questionnaire (PHQ-9). The PHQ-9 is a 9-item scale where respondents indicate how much they are bothered by certain problems on a 4-point scale where 0 = not at all and 3 = nearly every day. Total scores range from 0 to 27 with degree of depression considered minimal for scores between 0-4, mild for scores of 5-9, moderate for scores of 10-14, moderate to severe for scores 15-19, and severe for scores of 20-27.
- Self-Efficacy [Baseline, 6, 12, and 24 months]
Participants' self-efficacy level will be measured by the Diabetes Empowerment Scale (DES-SF). The scale consists of 10 items and reports in a 5-points Likert scale. An item checked "strongly agree" receives 5 points; "agree" - 4 points; "neutral" - 3 points; "disagree" - 2 points; and "strongly disagree" receives 1 points. Minimum score is 8, max is 40. Higher scores indicate greater sense of empowerment to self-manage condition.
- Social support [Baseline, 6, 12, and 24 months]
Social support will be measured by the Diabetes Care Profile(DCP) Scale. The scale consists of 8 items. The possible responses to each question were: "Strongly Agree," "Somewhat Agree," "Neutral","Somewhat Disagree," "Strongly Disagree" or "Does Not Apply."
