Brief summary

This study aims at evaluating the feasibility of an intervention based on the use of a mobile-device based system delivering automated, tailored brief text messages to offer support for medicine use and lifestyle recommendations alongside usual care to people with type 2 diabetes.

Detailed description

A list of patients registered in primary care centers of the Balearic Islands and potentially meeting the eligibility criteria will be obtained from electronic health records (EHRs). A research assistant will contact the potential participants via phone to invite them to the study and confirm eligibility. All eligible participants will complete informed consent followed by baseline assessment over the phone before randomization. Participants will be randomly allocated using a computer-generated randomization sequence. All participants will continue with their usual diabetes care including all medical visits, tests, and diabetes support programs throughout the study. In addition, the intervention group will receive the text messaging intervention. Control participants will receive usual care only. After three months of follow-up, all participants will complete post-intervention assessments via phone interview. Data on glycemic control (HbA1c) at baseline and post-intervention will be extracted from EHRs, as according to the protocol used for primary care providers in the Balearic Islands, patients with poor glycemic control (HbA1c \>8% ) must request an HbA1c determination every six months. Results of the most recent determination will be extracted from electronic medical records. For those patients with no recorded HbA1c within the previous three months, the research assistant will contact the primary care center and the patient to arrange blood test analyses.

Interventions

Participants will receive daily (from monday to friday) text messages in their mobile phones during three months.

MeasureTime frameDescription
Glycated Hemoglobin (HbA1C)Baseline and post-intervention at 3 monthsHbA1c was extracted as percentage which is calculated following the standard formulae \[HbA1c(%)=(HbA1c(mmol/mol)+23.5)/10.93\] based on its concentration in blood samples. It identifies average plasma glucose concentration.

Number of Participants Classified as Adherent Based on Self-reporteAdherence to Antidiabetic Medication (7 Items ad Hoc Questionnaire)Baseline and post-intervention at 3 monthsNumber of participants classified as adherent based on Self-reported adherence to glucose medications was measured with a 7-items ad hoc questionnaire adapted from Chaves-Torres et al. for people with type 2 diabetes. Participants who obtained 7 points were considered adherent while the ones with \< 7 points were non-adherent.

MeasureTime frameDescription
14-point Mediterranean Diet Adherence Screener (MEDAS-14)Baseline and post-intervention at 3 monthsThe 14-point Mediterranean Diet Adherence Screener (MEDAS-14) questionnaire was registered at baseline and post-intervention. Participants were classified as low adherents (≤5), moderate adherents (6 to 9 points) or high adherents (≥10 points) according to the results obtained that can range between 1 to 14 points. After that, we joined moderate adherents with high adherents and tagged them as adherents to the Mediterranean Diet, while low adherents were considered non-adherents to the Mediterranean diet. Therefore, we presented the number of participants adherent to the MediterraneanDiet. A higher score means a higher adherence to Mediterranean diet.

Being Adherent to Physical Activity Recommendations Based on Having Moderate or High Levels of Physical Activity Resulted From the International Physical Activity Questionnaire (IPAQ)Baseline and post-intervention at 3 monthsA 6-items adapted from the short version of the International Physical Activity Questionnaire (IPAQ) (11) was registered at baseline and post-intervention. Participants were classified as having a low, moderate or high level of physical activity based on metabolic equivalent of task (METs) calculation. After that, we joined the participants that presented moderate or high level of physical activity and tagged them as adherents to Physical Activity recommendations, while having low levels of Physical Activity was considered as being non-adherent to the Physical Activity Recommendations. Therefore, we presented the number of participants adherent to the Physical Activity Recommendations. We used the available tool from the Public Health System of the Balearic Islands: https://apps.caib.es/plasalutfront/formularios/ipaq/ipaq.xhtml

DIABE-TEXT
Participants allocated to the intervention group will receive text messages in their mobile phones with content about diabetes management, general information about diabetes, medicines, diet and physical activity recommendations and motivational prompts to engage participants in a healthy lifestyle and a good adherence to medication plan. They will also receive reminders for healthcare visits, drug dispensation from the pharmacy and updated results from blood test records.

Outcome results

Primary

Glycated Hemoglobin (HbA1C)

HbA1c was extracted as percentage which is calculated following the standard formulae \[HbA1c(%)=(HbA1c(mmol/mol)+23.5)/10.93\] based on its concentration in blood samples. It identifies average plasma glucose concentration.

Time frame: Baseline and post-intervention at 3 months

Population: The number analyzed post-intervention differs from overall number analyzed because of losses to follow-up.
