The city of Matão, located in São Paulo state, with a population around 80.000 inhabitants, has conditions to develop a community-based stroke study, which can answer important questions regarding epidemiological data over the time.\n\nTherefore, the purpose of this prospective community based study is to observe trends in stroke incidence, types and sub-types of stroke, risk factors, prognosis, 30 days and one year case-fatality during a follow-up of ten years.\n\nThis study offers the opportunity to conduct an epidemiological study of high quality which can obtain data to formulate public politics to reduce the social and economic impact of stroke in Brazil.', 'detailedDescription': 'Introduction\n\nCommunity-based stroke studies can answer important questions regarding incidence, case fatality, recurrence, disability, assessment of risk factors and quality of stroke services.\n\nBrazil had the highest age-adjusted stroke death rate of all Latin-American countries and the risk of premature death due to stroke is one of the highest in the world. Although, a decline in Brazilian stroke incidence and mortality has been observed in last years, stroke still has an important social burden in the country.\n\nThe purpose of this study is to observe trends in stroke incidence, types and sub-types of stroke, risk factors, prognosis, 30 days and one case-fatality during a follow-up of ten years.\n\nObjectives\n\nThe objectives of this project is to analyze:\n\nThe incidence of first-ever-in-a-lifetime stroke and incidence of pathological types, subtypes, and rare causes Case fatalities Prognosis Early and long-term case-fatality rates Poststroke morbidity Disability and handicap pos-stroke Risk factors Complications after stroke Recurrent stroke Other vascular events Trends in stroke incidence\n\nSubjects and Methods\n\nStudy Design A prospective population-based study is being performed since August, 1, 2015\n\nSite of Investigation\n\nMatão is a city located in São Paulo state, in the Brazilian southwest, 300 km northwest of the state capital. Matão population was 78.690 in 2015 and estimated population in 2025 is 80791 inhabitants. There is only 1 hospital in the city, which serves the whole city and 2 other small towns. This is a general secondary level public hospital, with 190 beds, including 18 beds in the intensive care unit and a radiology service with CT scan, the only one in the city. The emergency department attends to 5000 to 6000 people monthly; including emergency and urgency cases. The emergency department and intensive care unit take care of acute stroke patients according to a written protocol that includes hospitalization and a brain CT scan applied as soon as possible to all patients with suspected stroke.\n\nCase Ascertainment All the physicians in the city are instructed to refer suspected acute stroke patients to the research team or to the hospital emergency department. The neurologists of the research team check all radiology records in suspected cases of stroke. The hospital admission and discharge lists are checked weekly, searching for any suspected case. All death certificates from the study period are checked monthly to search for stroke patients who died in their homes and are not been referred to the hospital.\n\nInclusion criteria All suspected stroke patients living in Matão at an address belonging to the city are included, regardless of age. The stroke criteria is rapidly developing clinical symptoms and/or signs of focal and at time global loss of cerebral function, with symptoms lasting more than 24 hours or leading to death, with no apparent cause other than that of vascular origin. Only the first-ever-in-a-lifetime stroke is being included in the analysis.\n\nExclusion criteria Patients not living in Matão, who did not fulfill the clinical criteria for stroke, with CT scan findings incompatible with a clinical suspicion of stroke and with clinical evidence of a previous stroke event.\n\nFollow-Up All included cases are being followed-up prospectively by the research team during the first, third, sixth, months and 1 year after the stroke event with hospital visits. Patients unable to attend the scheduled visits or who had moved to another city are being contacted by telephone.\n\nClassifications and Definitions The subtypes of stroke are being classified as ischemic stroke and intracerebral hemorrhage on the basis of CT scan findings and subarachnoid hemorrhage on the basis of CT scan and cerebrospinal fluid findings. Ischemic stroke is subdivided into four subtypes according to the Oxfordshire Community Stroke Project classification. For prognosis, is considered independence in activities of daily living if patient reaches 100 points on the Barthel scale, independent gait if the patient reached 15 points in the mobility subsection of the Barthel scale, recurrent stroke if any new episode of focal cerebral dysfunction persisting 24 hours during the follow-up period.\n\nData Analysis The age- and sex-specific annual incidence of first-ever-stroke per 100 000 inhabitants it is being estimated according to the official system of the Brazilian Ministry of Health stratification and is presented as 10-year age bands as follows: younger than 45, 45 to 54, 55 to 64, 65 to 74, and 75 years or older. The incidence rate will be calculated as the number of cases divided by the population at risk in the specific age bands, according the respective year population. Inferential analyses will be performed by the 2-sided Fischer exact test, with the level of significance set at 5%.\n\nDiscussion\n\nPopulation-based studies can identify all types and sub-types of stroke in a community. Studies including just data from hospitals, may not include mild stroke that are not hospitalized and also severe stroke that die at home and do not have hospitals admission.\n\nAdditionally, it is fundamental that this studies should be prospective and in a long follow-up. As diagnostic of stroke is basically clinical, prospective studies allow more specific methods to define the type of stroke, risk factors, impairments and handicaps over time.\n\nThe paucity of data regarding incidence on long follow-up and the distinct etiologies as cause of stroke are being responsible as the main causes of the high incidence and case fatality in the world. This study in Matão offers the opportunity to conduct an epidemiologic study of high quality, which will be able to obtain data to formulate public politics to reduce the social and economic impact of stroke in Brazil.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'The study population belongs to Matão, Brazil, São Paulo state, located 300 km northwest of the state capital.
