Public knowledge of people visiting Imam Reza hospital regarding stroke symptoms and risk factors

Early recognition of stroke symptoms results in a lower time period after stroke onset to treatment with a better outcome. This depends on the awareness of patients, family members, and the general public.

The aim of this study was to evaluate public awareness about stroke risk factors, warning symptoms, and treatments.

This cross-sectional study was conducted as a hospital-based survey on 2712 people who visited clinics or emergency department of Imam Reza hospital for any reason, from March 2015 to February 2016. All subjects were interviewed face-to-face by four trained physicians and a structured, pre-tested questionnaire was filled.

The mean age of participants was 41.0 ± 12.1 years old. Considering Cincinnati prehospital stroke scale (CPSS) as the main diagnostic system, the percentage of participants that mentioned face asymmetry, speech disturbances, and arm paralysis as a symptom of stroke was 7, 1.5, and 7.9%, respectively. Meanwhile, 71.2% of participants could not mention any of the stroke symptoms. Among participants, 20.2% did not know any of stroke risk factors although 35.1, 27.8, and 17.3% could name one, two and three or more risk factors, respectively. Among participants, only 1.1% were aware of thrombolytic therapy (t-PA) as a first-line drug for stroke treatment.

In this study, public knowledge regarding stroke symptoms, risk factors, and therapy approaches was low. Taken together, public education is necessary to reduce the time for recognition of stroke symptoms and subsequently prompt and proper proceeding seems to be necessary for the community.
