A Multicentre, Randomised Study to Examine the Effects of Telephone Intervention in Patients With Coronary Heart Disease and Diabetes

Detailed Description

Study-design A 2-year multicentre, randomised controlled open study involving 5 HA hospitals in Hong Kong.

Subjects and method One thousand two hundred and sixteen patients admitted to hospital with principle diagnosis of coronary heart disease and known or newly confirmed diabetes on oral glucose tolerance test will be enrolled. Patients in the intervention arm (n=608) will receive telephone intervention between clinic visits by diabetes nurse educator using structured counselling tools with particular emphasis on adherence to lifestyle modification and medications as well as self-monitoring of blood glucose, blood pressure and body weight. Patients in control group (n=608) will not receive telephone intervention. Both groups will be followed up by their usual medical teams in their hospitals upon discharge.

Clinical endpoints Primary endpoint is the composite of death and/or cardiovascular related hospitalisations. Secondary endpoints include hospitalisations due to cardiovascular events, number of hospital admissions, total number of days of hospital stay and attendance at the Accident and Emergency Department.
