Prioritising prevention: Implementation of IGT Care Call, a telephone based service for people at risk of developing type 2 diabetes

Aim: To design, deliver and evaluate IGT Care Call, a telephone service providing a 6 month lifestyle education programme for people with impaired glucose tolerance (IGT). Methods: An observational study of IGT Care call, a programme providing motivational support and education using electronic scripts. The service was delivered to 55 participants, all of whom completed the course (an information pack and at least five telephone calls over 6 months). Clinical measurements were undertaken in General Practice at baseline, on completion of the programme and one year later. Results: Among the 40 participants for whom we have complete data available, one year after discharge, participants showed improvements in fasting plasma glucose (0.29 mmol/l, 95% CI 0.07 to 0.51), weight (2.81 kg, 95% CI 1.20 to 4.42) and BMI (1.06 kg/m(2), 95% CI 0.49 to 1.63). All differences were statistically significant (p
