Mobile Health Intervention for Improved Adherence in Type 2 Diabetes

Objectives of the Study: The study assessed patients' glycemic control, knowledge of type 2 diabetes (T2D) and adherence to medications, and evaluated the impact of a mobile telephone-based intervention on these indices.

Study design: Randomized controlled trial Study Setting: Diabetes Clinic, Endocrinology Unit, Department of Internal Medicine, Obafemi Awolowo University Teaching Hospital Ile Ife, Osun State Nigeria The study was structured in five stages. Study Duration: Seven months Stage 1: Baseline data Task 1: Baseline data for patients' glycemic control were obtained from one-year retrospective review of 1392 patients' files for glycated haemoglobin (HbA1c) measurements.

Task 2: Patients' baseline adherence data were obtained from one-year retrospective review of pharmacy refill records (clinic attendance) Task 3: Development and validation of research instruments (Questionnaires, Short Message Services (SMS).

Task 4: Recruitment and training of research assistants (2 hours daily for 3 days) Stage 2: Recruitment and randomization of participants Task 1: Enrolment of all newly-diagnosed patients (n = 120), enrolled in the Diabetes Clinic in the period of one month following Stage 1 Task 2: Obtaining of informed consent from all newly-diagnosed patients enrolled in the Diabetes Clinic in the one month following Stage 1 Task 3: Collection of participants' baseline knowledge data using structured questionnaire Task 4: Collection of baseline self-reported adherence data using the adapted 8-point Morisky Medication Adherence Scale (MMAS-8) instrument Task 5: Randomization of consenting participants into two equal (n = 60) control and intervention groups using a randomization software Stage 3: Intervention Task 1: Activation of short message services to participants in the intervention cohort at a frequency of one message per day for the period of 6 months.

Task 2: Follow up on clinic attendances of all participants for the period of 6 months Stage 4: Post-Intervention Review Task 1: Repeat administration of same questionnaires originally administered at Stage 2 to all participants Task 1: Review of participants' clinic attendance and pharmacy refill records Task 2: Review of participants HbA1c measurements from their records Stage 5: Data analysis Task 1: Demographic variables of participants were analyzed using descriptive statistics including frequency and percentages Task 2: Weighted mean scores were used to analyze knowledge and adherence scores Task 3: Two-sample t-test was used to compare pre- and post-intervention scores of knowledge and adherence Task 4: Chi square test was conducted to analyze associations between demographic variables and self-reported adherence data Task 5: Statistical package for the social sciences (SPSS) version 21 for windows software was used for data analysis at the p < 0.05 level of significance
