Influence of Decision-Makers' Perceived Risk on the Propensity for Intravenous Thrombolysis in Acute Ischemic Stroke: A Cross-Sectional Study.

aimsThis study investigates the degree of the perceived risk of intravenous thrombolysis in acute cerebral infarction among surrogate decision-makers and the factors influencing their propensity to make decisions about thrombolysis.

designAn investigation was conducted on a cross-sectional basis.

methodsWe recruited participants using a purposive sampling technique. All participants were recruited from the Advanced Stroke Centre in a tertiary care general hospital from January 2022 to December 2022. A total of 201 Surrogate Decision-Makers completed the survey. Using a self-designed questionnaire, the instrument of this survey contains three aspects of general information including risk perception level survey, propensity for thrombolysis, and consisting of 18 questions.

resultsRisk perception consists of three dimensions: economic risk perception, psychosocial risk perception, and physical functioning risk perception, and each dimension is scored in the range of 3-15 points. Higher scores indicate stronger risk perception. The mean risk perception score of acute ischemic stroke surrogate decision-makers was (11.26 ± 2.72). The average score of psychosocial risk perception was (10.71 ± 2.34); the score of physical function risk perception was (11.00 ± 2.37). The highest proportion of those choosing conservative treatment was 46.8%. The percentage of those willing to thrombolize was 27.4%, and those who were unsure about it was 25.9%. The degree of perceived economic risk, perceived psychosocial risk, and perceived physical function risk all had a significant negative effect on the propensity to make decisions about thrombolysis after excluding the confounding interference of different ages, education levels, and monthly per capita household income.

conclusionThis study found a significant effect of risk-perception of the surrogate decision-maker on treatment propensity. Healthcare professionals should pay attention to guiding surrogate decision-makers to establish correct disease perception and risk-perception through effective communication during thrombolysis communication in acute ischemic stroke to relieve their decision-making pressure, shorten decision-making time and reduce Door-to-Needle time to improve patient prognosis and increase the rate of thrombolytic therapy. PATIENT OR PUBLIC CONTRIBUTION: This study is a questionnaire survey conducted by the investigator and no patient or public participation is required. IMPACT: The risk perception of surrogate decision-makers is likely to play an essential role in the decision-making process. However, increased risk perception and prolonged thrombolysis are due to a lack of knowledge about thrombolysis among surrogate decision-makers. Generalizing the need for intravenous thrombolysis may improve the rate of thrombolysis and thus provide clinical benefit to patients.
