Short Messaging Service for Optimizing Hemoglobin A1C Management in Low-Income Diabetics — SAMI  

Diabetes Clinical Trial

Official title: Use of a Short Messaging Service for Optimizing Hemoglobin A1C Management in Low-Income Diabetic Patients (SAMI TRIAL)

Status Completed

Clinical Trial Summary

The purpose of this study is to determine the impact of two-way short message service (SMS) on glycemic control in low-income, poorly-controlled adult diabetic patients.

Clinical Trial Description

This multi-center, unblinded, prospective randomized controlled trial will enroll adult diabetic patients of the Wilson Community Health Center, Harvest Family Health Center, and Freedom Hill Community Health Center living below 200% of 2013 poverty level with a serum hemoglobin A1C >9% and who currently own a mobile device with text messaging capacity. After written informed consent has been obtained, subjects will be randomized to intervention or control group (1:1), stratified based on insulin initiation within 1 week of study inclusion. Participants randomized to the intervention group will be further divided into subgroups as "insulin user" or "non-insulin user" and both will receive SMS messages every 7 days. The content of the message consist of medication reminders, reporting of blood glucose results, insulin technique assessment (if applicable), or d) medication adherence assessment. Participants will be asked to respond with a simple text within 7 days. The intervention group will receive the standard medical appointment reminder via telephone one to two business days prior to the appointment at the Health Center PLUS a unidirectional text message two business days prior to scheduled health center appointments. Control group participants will receive the standard medical appointment reminder via telephone one to two business days prior to the appointment at the health center. All participants in the study (control and intervention) will undergo venipuncture at 3 months (+/-) 2 weeks for the determination of hemoglobin A1C. Demographic information, and frequency of hemoglobin A1C concentrations in the past 6 months will be assessed at baseline. Each week for 12 weeks, the number of texts sent per week and by type, percent of respondents weekly by text or by phone, content of participant responses, number of patients unable to be reached via text, total investigator time spent per week, and time spent per contact will be recorded. At the three month visit, the hemoglobin A1C concentration, blood transfusions since study initiation, and medication changes will be recorded. ;
