  Purpose
The purpose of this study is to investigate whether a nurse-based intervention, consisting of structural informative consulting and motivational counseling, on top of usual care with or without personalized web-based visualization of cardiovascular risk levels, improves the medication adherence in high risk cardiovascular patients.

Condition Intervention
Cardiovascular Diseases Behavioral: Life style counseling Behavioral: an individualized web portal Behavioral: individual and group consultations

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Prevention
Official Title: Nurse- and Web Based Intervention to Improve Medication Adherence in High Risk Cardiovascular Patients.

Further study details as provided by Bas Bredie, Radboud University:

Primary Outcome Measures:
  • Change in degree of Adherence [ Time Frame: Change from baseline in degree of Adherence at 12 month ]
    The degree of Adherence to medication for each group at 12 month from baseline, as calculated by prescription refill data


Secondary Outcome Measures:
  • Clinical outcome [ Time Frame: Change from baseline in level of LDL-Cholesterol at 12 months ]
    Change in LDL-Cholesterol level in each group at 12 months from baseline

  • Clinical outcome [ Time Frame: Change from baseline in Sytolic Blood Pressure at 12 months ]
    Change in Systolic Blood Pressure in each group at 12 months from baseline

  • Clinical outcome [ Time Frame: Change from baseline in Body Mass Index at 12 months ]
    Change in Body Mass Index (BMI) in each group at 12 months from baseline

  • Clinical outcome [ Time Frame: Change from baseline in Waist Circumference at 12 months ]
    Change in Waist Circumference in each group at 12 months from baseline

Arms Assigned Interventions
Experimental: Lifestyle counseling
Group consultation and individual nurse consultation
Behavioral: Life style counseling
A nurse-based intervention with face-to-face contacts based on motivational interviewing techniques and influence on behavioral determinants. Well-trained nurses in our hospital will apply these behavioral change interventions. An individual contact will take about twenty minutes.
Behavioral: an individualized web portal
This website shows patient's lab results, life style issues, blood pressure and weight in various risk monitors. These lab results and lifestyle changes will be visualized in risk monitors and provide structural feedback to the patient. The results of the screening and the two additional visits can be seen by the patient.
Behavioral: individual and group consultations
group consultations with peers and a nurse individual consultation with a nurse
Experimental: e health
An individual web based entry
Behavioral: an individualized web portal

No Intervention: usual care
Usual care

Detailed Description:

Poor adherence to medication is one of the limitations in the treatment of cardiovascular disease. As a consequence the risk of premature death, hospital admissions and related costs is increasing. Therefore, detection of apparent poor adherence and interventions to improve adherence, are of great importance to enhance cardiovascular risk management over time.

This study is a prospective randomized trial, which compares 1) usual care with 2) the effect of a personalized visualization of cardiovascular risk levels (website) to support self management and 3) the additional effect of a communication intervention by a nurse on adherence on top of 2). Adherence is determined and continuously monitored with a dedicated calculation of refill data obtained from patient's pharmacy.
