A pilot-study to identify the feasibility of an Internet-based coaching programme for changing the vascular risk profile of high-risk patients.
OBJECTIVE To evaluate the feasibility of a web-based coaching programme for vascular risk factor treatment , to describe the patterns of use and to measure changes in risk factors . METHODS Patients with a clinical manifestation of arterial disease and Internet access were asked to participate in the nurse-led Internet-based risk factor management programme . At the first clinic visit , a personalized action plan was made for the treatment of risk factors . Patients were instructed on communication with a specialized nurse through Internet and encouraged to enter self-measured risk factor levels at their personalized website . The nurse practitioner replied on working days and gave feedback , support , and recommendations on lifestyle and medical treatment . After 6 months , risk factors were re-measured . RESULTS Fifty patients participated , 70 % were overweight , 64 % had hypertension , 42 % hyperlipidemia , and 24 % smoked at baseline . During 6 months , the log-in average at the individual website was 35 times per patient ( 1.3 log-ins/week ) ; while the nurse practitioner logged-in at the overall website 23 times/week . The website was hardly used by five patients . Most e-mail messages were sent by patients for hypertension ( 211 times ) and obesity ( 203 times ) , whereas the nurse practitioner sent nearly twice as many e-mail messages for hypertension ( 400 times ) and obesity ( 455 times ) . The level of most risk factors decreased and the fraction of achieved treatment goals increased ( blood pressure from 36 to 58 % , LDL-cholesterol from 58 to 64 % , glucose from 64 to 82 % ) . CONCLUSIONS A web-based vascular risk factor intervention programme is feasible ; it is frequently used by patients and suitable to decrease the level of several risk factors . It has the promise of being an efficacious intervention for risk factor sanitation in patients with symptomatic vascular disease . PRACTICE IMPLICATION S An Internet-based individualised risk management programme could make patients aware of their self-management capability and may contribute to risk factor reduction
