| E-Rehabilitation an Internet and mobile phonebased tailored intervention to enhance selfmanagementof Cardiovascular Disease: studyprotocol for a randomized controlled trial |
| Scritto da BMC Cardiovascular Disorders |
 Background:Cardiac rehabilitation is very important for the recovery and the secondary prevention ofcardiovascular disease, and one of its main strategies is to increase the level of physicalactivity. Internet and mobile phone based interventions have been successfully used to helppeople to achieve this. One of the components that are related to the efficacy of theseinterventions is tailoring of content to the individual. This trial is studying the effect of alongitudinally tailored Internet- and mobile phone based intervention that is based on modelsof health behaviour, on the level of physical activity and the adherence to the intervention, asan extension of a face-to-face cardiac rehabilitation stay.Methods:A parallel group, cluster randomized controlled trial. The study population is adultparticipants of a cardiac rehabilitation programme in Norway with home Internet access andmobile phone, who in monthly clusters are randomized to the control or the interventioncondition. Participants have access to a website with information regarding cardiacrehabilitation, an online discussion forum and an online activity calendar. Those randomizedto the intervention condition, receive in addition tailored content based on models of healthbehaviour, through the website and mobile text messages. The objective is to assess the effectof the intervention on maintenance of self-management behaviours after the rehabilitationstay. Main outcome is the level of physical activity one month, three months and one yearafter the end of the cardiac rehabilitation programme. The randomization of clusters is basedon a true random number online service, and participants, investigators and outcome assessorare blinded to the condition of the clusters.DiscussionThe study suggests a theory-based intervention that combines models of health behaviour inan innovative way, in order to tailor the delivered content. The users have been activelyinvolved in its design, and because of the use of Open-Source software, the intervention caneasily and at low-cost be reproduced and expanded by others. Challenges are the recruitmentin the elderly population and the possible underrepresentation of women in the study sample.Funding by Northern Norway Regional Health Authority.Trial registrationTrial registry www.clinicaltrials.gov: NCT01223170.Fonte: BMC Cardiovascular Disorders |
