In these patients, implementing secondary prevention is a critical challenge and new strategies need to be developed to close the gap between clinical practice and evidence-based recommendations. We describe the protocol of a randomised clinical trial that aims to evaluate the efficiency and effectiveness of an intensive multidisciplinary follow-up of patients compared with standard care.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and analysis<\/jats:title><jats:p>The DiVa study is a randomised, prospective, controlled, multicentre trial including patients &gt;18 years old with a first or recurrent stroke (ischaemic or haemorrhagic) or TIA, or a type I or II MI, managed in one of the participating hospitals of the study area, with a survival expectancy &gt;12 months. Patients will be randomised with an allocation ratio of 1:1 in two parallel groups: one group assigned to a multidisciplinary, nurse-based and pharmacist-based 2-year follow-up in association with general practitioners, neurologists and cardiologists versus one group with usual follow-up. In each group for each disease (stroke\/TIA or MI), 430 patients will be enrolled (total of 1720 patients) over 3 years. The primary outcome will be the incremental cost\u2013utility ratio at 24 months between intensive and standard follow-up in a society perspective. Secondary outcomes will include the incremental cost\u2013utility ratio at 6 and 12 months, the incremental cost-effectiveness ratio at 24 months, reduction at 6, 12 and 24 months of the rates of death, unscheduled rehospitalisation and iatrogenic complications, changes in quality of life, net budgetary impact at 5 years of the intensive follow-up on the national health insurance perspective and analysis of factors having positive or negative effects on the implementation of the project in the study area.<\/jats:p><\/jats:sec><jats:sec><jats:title>Ethics and dissemination<\/jats:title><jats:p>Ethical approval was obtained and all patients receive information about the study and give their consent to participate before randomisation.
