A System Architecture Overview for the Support through Mobile Messaging and Digital Health Technology for Diabetes (SuMMiT-D) Pilot and Feasibility Studies (Preprint)

<sec> <title>BACKGROUND</title> <p>Diabetes is a highly prevalent long-term condition with high levels of morbidity and mortality [1]. People with diabetes commonly worry about their diabetes medicines and do not always take them regularly as prescribed [2]. This can lead to poor diabetes control. The SuMMiT-D study aims to deliver brief messages as tailored interventions to support people with type 2 diabetes in better use of their diabetes medicines to improve treatment adherence and health outcomes.</p> </sec> <sec> <title>OBJECTIVE</title> <p>This paper describes the overall architecture of a message delivery system used in the pilot and feasibility studies of SuMMiT-D and reports its performance.</p> </sec> <sec> <title>METHODS</title> <p>The SuMMiT-D system includes several platforms and resources. Its core component is called the “clinical system”, and is responsible for interacting with the participants for personalisation and tailoring of messages through receiving and sending SMS text messages from and to them.</p> </sec> <sec> <title>RESULTS</title> <p>For the pilot study, a total of 48 participants were recruited; they had a median age of 64 years, Q_1,〖 Q〗_3=[54.5,69]. For the feasibility study, a total of 209 participants were recruited and randomised; they had a median age of 65 years, Q_1,Q_3=[56,71], with 41.15% female. The participants used the SuMMiT-D system for up to 6 months, and had a wide range of different interactions with the system.</p> </sec> <sec> <title>CONCLUSIONS</title> <p>A system was developed to successfully deliver brief messages as health interventions to more than 200 people with type 2 diabetes via SMS text messages.</p> </sec> <sec> <title>CLINICALTRIAL</title> <p>ISRCTN13404264</p> </sec>
