Similarly , there was no clear evidence of effect for cardiovascular risk factors , although again the number of studies reporting these was small .
There was some evidence for beneficial effects on HRQOL , dietary outcomes , and physical activity , although firm conclusions can not yet be made .
The effects on healthcare utilisation and cost-effectiveness are also inconclusive , and trials are yet to measure the impact of  Internet interventions on compliance with medication .
BACKGROUND The Internet could provide a means of delivering secondary prevention programmes to people with coronary heart disease ( CHD ) .
OBJECTIVES To determine the effectiveness of Internet-based interventions targeting lifestyle changes and medicines management for the secondary prevention of CHD .
Providing a Web-based Online Medical Record with Electronic Communication Capabilities to Patients With Congestive Heart Failure: Randomized Trial
Background It is possible to provide patients with secure access to their medical records using the Internet . Such access may assist patients in the self-management of chronic diseases such as heart failure . Objective To assess how a patient-accessible online medical record affects patient care and clinic operations . The SPPARO ( System Providing Access to Records Online ) software consisted of a web-based electronic medical record , an educational guide , and a messaging system enabling electronic communication between the patient and staff . Methods A r and omized controlled trial was conducted in a specialty practice for patients with heart failure . Surveys assessing doctor-patient communication , adherence , and health status were conducted at baseline , 6 months , and 1 year . Use of the system , message volume , utilization of clinical services , and mortality were monitored . Results One hundred and seven patients were enrolled ( 54 intervention and 53 controls ) . At 12 months , the intervention group was not found to be superior in self-efficacy ( KCCQ self-efficacy score 91 vs. 85 , p=0.08 ) , but was superior in general adherence ( MOS compliance score 85 vs. 78 , p=0.01 ) . A trend was observed for better satisfaction with doctor-patient communication . The intervention group had more emergency department visits ( 20 vs. 8 , p=0.03 ) , but these visits were not temporally related to use of the online medical record . There were no adverse effects from use of the system . Conclusions Providing patients with congestive heart failure access to an online medical record was feasible and improved adherence . An effect on health status could not be demonstrated in this pilot study
