Using an automated interactive telephone programme to improve diabetes management: The TLC Diabetes project

Project Team

Project Overview

The Telephone-Linked Care (TLC) Diabetes system is designed to educate and coach patients to improve nutrition, physical activity, blood glucose testing and medication taking. It is based on technology developed at Boston University Medical Centre over the past 15 years under the lead of Professor Robert Friedman. TLC complements the care currently provided to people with Type 2 diabetes by general practitioners, endocrinologists, diabetes educators and other health workers.

Participants with Type 2 Diabetes call the TLC system which consists of a computer equipped with sophisticated speech recognition and voice processing software, from a home or mobile phone to engage in weekly “conversations”. Prior to each call, users upload their most recent glucose meter results via a data transmitter connected to a dedicated mobile phone.

Sub-Projects

1. Trial of the TLC system in Australia

This project focused on identifying the key issues required to adapt the original TLC system designed for use within the United States, for application within an Australian setting. A pilot trial TLC system was undertaken using the Physical Activity module. This trial highlighted that language, accent and colloquialisms, socio-cultural/environmental factors, and health guidelines and systems needed to be changed to reflect the Australian context. The acceptability of the system was also investigated, with participants reporting a high level of satisfaction with the program. The results of this pilot study were used to transfer a more complex system aimed at addressing a number of behaviours associated with successful diabetes self-management.

1. Development and trial of the Australian TLC Diabetes system

This project involved the review of a number of the original system components necessary to transfer the TLC system to an Australian context, specific to diabetes self-management. Initially, over 2000 of the original voice scripts were reviewed by a group of Australian health professionals. Each script was rigorously assessed in terms of currency and existing public health campaigns, and relevant amendments made. In addition, new scripts were developed to account for the fundamental differences in health guidelines and systems between the two countries.

In addition, to the adjustment of the TLC program to meet the needs of an Australian diabetic population, this project also involved the development of a novel device to upload blood glucose readings. Developed in partnership with Alive Technologies, AliveConnect allows the user to automatically upload readings from a blood glucose meter via a Bluetooth connection to the TLC Diabetes system. The AliveConnect system ensures that accurate feedback on blood glucose readings is provided to the user during calls to the TLC system.

1. Implementation of the TLC Diabetes system

Currently a study is being undertaking to evaluate the effectiveness of the TLC system among adults with type 2 diabetes. Based in Brisbane, this randomised controlled-trial will compare the blood glucose control, quality of life, medical costs, and a number of other self-management behaviours between those people allocated to the TLC (intervention) group and those allocated to the usual care or control (placebo) group.

The project is supported by funding from the HCF Health and Medical Research Foundation, NHMRC and Queensland Health. TLC Diabetes is designed to educate and coach patients to improve nutrition, physical activity, blood glucose testing and medication taking.
