Agreement with evidence for tissue Plasminogen Activator use among emergency physicians: a cross-sectional survey

Background: Emergency department staff play a crucial role in the triage of stroke patients and therefore the capacity to deliver time-dependent treatments such as tissue Plasminogen Activator. This study aimed to identify among emergency physicians: (1) rates of agreement with evidence supporting tissue Plasminogen Activator use in acute stroke care. ; (2) individual and hospital factors associated with high agreement with evidence supporting tissue Plasminogen Activator use. Methods: Australian fellows and trainees of the Australasian College for Emergency Medicine were invited to complete an online cross-sectional survey assessing perceptions of tissue Plasminogen Activator use in acute stroke. Demographic and hospital characteristics were also collected. Results: 429 Australasian College for Emergency Medicine members responded (13% response rate). Almost half (47.2%) did not agree with any statements regarding the benefits of tissue Plasminogen Activator use for acute stroke. Perceived routine administration of tissue Plasminogen Activator by the head of respondents' emergency department was significantly associated with high agreement with the evidence supporting tissue Plasminogen Activator use in acute stroke. Conclusions: Agreement with evidence supporting tissue Plasminogen Activator use in acute stroke is not high among responding Australian emergency physicians. In order for tissue Plasminogen Activator treatment to become widely accepted and adopted in emergency settings, beliefs and attitudes towards treatment need to be in accordance with clinical practice guidelines.
