Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients in the intervention group will be invited to participate for 12 months in "MiDoctor," an automated system that monitors individuals with chronic diseases and promotes self-care by providing timely diagnosis, automated calls, and continual reminders via text messaging. The system reinforces patient attendance, helps patients adhere to medication and lifestyle changes, and alerts health personnel to inadequate adherence or changes in risk factors. Specifically, MiDoctor is a web-based system with an interactive voice response (IVR) component and SMS components. The system makes automated phone calls and sends SMS to the patient and, depending on the patient's response, it will send an email alert and place the patient on a work list for the clinical team to respond. The system calls the patient approximately once a week and sends them 1 SMS per week. Each automated phone call lasts approximately 1.5 minutes.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A total of 1,054 eligible patients was identified. Among this group, 650 were randomly assigned to the intervention group, while the remaining 404 were assigned to the control group. Allocation concealment through central randomization via computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Each of the 1,054 eligible patients was assigned a random number via a computerized random number generating routine. The patients were then ordered according their random number, and the lowest 650 values were assigned to the intervention group.
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
When an individual in the intervention group is invited to participate, any other eligible individual residing in the same household will also be invited, even if that individual was originally designated as a control.
Phase
Type of endpoint/s
Efficacy
Statistical methods / analysis
Since the intervention constitutes an invitation to participate in the MiDoctor program, the study results will be subject to intention-to-treat (ITT) analysis. In addition, a supplementary per-protocol (PP) analysis will be performed based upon acceptance of the invitation to participate. The sample sizes were designed to detect a difference of 0.3 units of hemoglobin A1c at a significance level of 5% and a power of 80%, based on a standard deviation of A1c equal to 1.5.

Summary
Brief summary
A randomized controlled study of MiDoctor, an automated system that uses text messaging (SMS) to reinforce patient attendance, helps patients adhere to medication and lifestyle changes, and alerts health personnel to inadequate adherence or changes in risk factors. The study population consists of 1,054 patients with diabetes type 2, at least 18 years old, registered at Hospital de Curacavi, Chile, of whom 650 will be invited to participate in MiDoctor, while 404 controls will receive their usual care. One-year endpoints will include hemoglobin A1c, blood pressure, LDL cholesterol, urinary microalbumin, and patient adherence to appointments and medications. Intention to treat (ITT) analysis is planned, along with a supplementary per-protocol (PP) analysis of based upon acceptance of the invitation to participate.
