Associations between Ischemic Stroke Follow-Up, Socioeconomic Status, and Adherence to Secondary Preventive Drugs in Southern Sweden: Observations from the Swedish Stroke Register (Riksstroke)

Research output: Contribution to journalArticle


Background: Currently, the knowledge that one has on adequate stroke follow-up practices is limited. We report associations between 90-day stroke follow-up, socio-economy and adherence to secondary prevention in southern Sweden. Methods: Data on 5,602 patients with ischemic stroke January 1, 2008-December 31, 2010, were obtained from Riksstroke and linked to official registers for information on education, birth country, doctor's follow-ups, and secondary prevention. Primary adherence at 4 months and persistence at 14 months post-stroke were calculated for warfarin, statins, antihypertensive, and antiplatelet drugs. Results: The 90-day follow-up rate was 75%. Patients not receiving a 90-day follow-up had lower age-adjusted OR of persistent drug use at 14 months for antihypertensive agents (OR = 0.74, 95% CI 0.60-0.91) and for antiplatelet drugs (OR = 0.72, 95% CI 0.60-0.87). Drug adherence rates 14 months post-stroke were 85% for antiplatelet drugs, 69% for warfarin, 88% for antihypertensive agents, and 76% for statins. One in three patients discontinued using one or more drug class within 14 months, and nonadherence was associated with activities of daily living dependency at 3 months (age-adjusted OR 0.63, 95% CI 0.57-0.69), but not with age, gender, or educational status. Conclusions: The use of secondary preventive drugs decreases over the first year after stroke and remains suboptimal. Specific reasons for nonadherence warrant further study.
