Plain English summary of protocol

Background and study aims
People with diabetes mellitus (DM) managing newly initiated insulin or requiring intensification of insulin therapy require frequent glucose monitoring and timely insulin adjustments. This study explores whether an integrated telehealth program using Bluetooth-enabled glucometers can enhance glycaemic control and reduce diabetes-related distress compared to traditional glucometers.

Who can participate?
People aged between 21 and 70 years with DM who were on newly initiated insulin or experiencing intensification of insulin therapy for diabetes management from a tertiary hospital.

What does the study involve?
Participants will be randomly allocated to either the intervention group (using a Bluetooth-enabled glucometer and mobile phone app) or the control group (using a manual logbook). They answer questionnaires relating to quality of life and distress from diabetes. In total, about 11 ml of blood will be collected for clinical tests, HbA1c and cholesterol levels (lipid panel) requested by the diabetes doctor as part of participants' routine follow-up. Participation in the study will last 22 to 28 weeks. Participants will be expected to perform structured self-monitoring of blood glucose based on their insulin regime throughout the study period. Participants will need to visit the doctor’s office two times in the course of the study and will receive phone consultations every 2 weeks for 3 sessions.

What are the possible benefits and risks of participating?
Benefits include having closer monitoring and analysis of self-monitoring blood glucose (SMBG) by a diabetes nurse, and closer titration of insulin therapy to achieve targets. Possible risks include technical error, where SMBG readings are not transferred to the mobile phone app (for participants in the intervention group). Participants in the intervention group will be using a free, commercially available mobile phone app, which they have to agree to the terms and conditions of the designers of the mobile phone app. There is a risk of privacy breach since participants' information will be stored by the mobile App on an external server. However, there will be no sharing of information between the mobile App company and the hospital.

Where is the study run from?
Tan Tock Seng Hospital (Singapore)

When is the study starting and how long is it expected to run for?

Health condition(s) or problem(s) studiedType 2 diabetes mellitus
InterventionThis interventional study was a 6-month, single-centre, two-armed, open-labelled parallel randomized controlled trial, where participants with diabetes mellitus newly started on insulin or requiring intensification of insulin therapy were assigned to either the intervention group or control group via a 2:2 ratio using a computer-generated randomization sequence with variable block sizes of 4, overseen by a statistician who was independent of the clinical team to maintain allocation concealment

The intervention group used a Bluetooth-enabled glucometer (ACCU-CHECK Instant) that automatically syncs blood glucose readings to a mobile app (MySugr), while the control group used a standard glucometer (ACCU-CHECK Performa) and manually logged blood glucose readings in a physical logbook.

IPD sharing planThe datasets generated and/or analysed during the current study will be published as a supplement to the results publication. Datasets include analyses of participants' cardiometabolic parameters, distress (PAID) and satisfaction measures (GMSS) using an intention-to-treat approach. Data will be analysed by paired t-test results for within-group changes, mixed-effects models for effects over time, and simple linear regression for effects across subgroups.
