Stroke prevention--a population screening day in district XII of Budapest

Along with advances in the treatment of acute stroke, new efforts have been made to enhance efficiency of the prevention of cerebrovascular diseases. Population screening is a way to contact high-risk patients, and there is an increasing international and national experience with the procedure. However, efforts are associated with high costs, so an efficient method, complying with local features, should be selected from the various methods. A stroke prevention day was organized in Szent János Hospital, localized in district XII, and data were analyzed. Taking advantage of the potentials of a large hospital, a comprehensive risk assessment - within the capacity of health care workers - was performed. Program and contact information of the screening day was published in the local newspaper of the district. Data of 48 residents of the district were analyzed. In addition to neurologists, a radiologist, a cardiologist and an ophtalmologist, as well as health care workers were involved in the project. A data sheet was filled in for all participants, including known risk factors, BMI, blood pressure and serum cholesterol levels. All participants had duplex sonography of the cervical vessels, cardiac evaluation and ophtalmic examination. Data were analyzed anonymously, and - if participants approved - postcode and educational level were also recorded. Among the 48 individuals screened, 35 were female and 13 were male. Average age was 62.86 (+/- 8.57) years, and participants were typically of higher educational level. 5 individuals had no known risk factors, most of them had 2-3 risk factors, and multiple risk factors were not uncommon. Individuals with six and seven risk factors were also found. 20 of 27 patients with known hypertension had target blood pressure levels. By duplex sonography, 36 individuals had mild, 4 had significant atherosclerosis. There was no significant carotid stenosis or occlusion. Based on ophtalmic evaluation, 26 patients had signs of vascular disease (mainly hypertensive fundus changes). Cardiac evaluation detected 14 patients with cardiovascular risk. The high standard of primary care in the district was reflected by the fact that all the 6 high-risk individuals were already in the care of general practitioners (GP-s). One of the main conclusions from the evaluation of the data is that the press, family and local communities play a major role in recruiting people for a screening day. In order to increase efficiency and cost-effectiveness of the program, GP-s should also be involved in the planning process, because efficiency may be increased by pre-selecting high-risk individuals.
