Abstract

Objectives: To investigate the impact of the Danish stroke campaign, 1 year after initiation.

Materials & methods: The campaign ran in various media during 2019-2020. We performed a two-centre, repeated cross-sectional study in 2018 (before campaign) and again in 2020 based on data from structured interviews of patients and bystanders, medical records and the Danish Stroke Registry. Primary outcomes were patient delay and system delay. Patient delay is defined as the time from symptom onset until the first contact to a healthcare professional, whereas system delay is the time from this contact until arrival at the stroke centre. Secondary outcomes were primary emergency medical services (EMS) contact, arrival at a stroke centre within 3 h of symptom onset, initiation of reperfusion therapy and knowledge of ≥2 core symptoms of stroke.

Results: We included 852 patients with stroke or transient ischemic attack. Patient delay and system delay were a median of 166 min and 96 min before the campaign and were non-significantly reduced by 16 min (95% CI -128 to 97) and 7 min (95% CI -21 to 6) in the second period. We found no significant differences in the clinical outcomes. The knowledge of ≥2 core symptoms increased from 22% to 30% (OR 1.63; 95% CI 1.15 to 2.30) in patients and from 53% to 65% (OR 1.81; 95% CI 1.24 to 2.64) in bystanders.

Conclusion: Patient delay, system delay and clinical outcomes remained relatively unchanged. However, the knowledge of core symptoms had improved 1 year after campaign initiation.
