Secondary prevention after stroke/transient ischemic attack: A randomized audit and feedback trial

Abstract

Objectives:The clinical benefits of use of secondary preventive pharmacotherapy in ischemic stroke/TIA have been previously demonstrated. A potential target for facilitating the use of recommended medications is primary care physicians.Therefore, we carried out an audit and feedback intervention aimed at primary care centers. The aim was to improve the use of secondary preventive stroke medications and diagnosis recording in ischemic stroke/TIA. Materials and Methods:The intervention consisted of structured, healthcare database-derived quality reports on secondary preventive medication use and diagnosis recording, sent in 2015 to half of the primary care centers in Stockholm County, with information specific to each primary care center. Medication dispensation (primary outcome) for statins, antihypertensives, antiplatelets, and anticoagulants, as well as diagnosis recording (secondary outcome), was compared between intervention centers and control centers in the 18 months following the intervention. Outcome data were derived from the healthcare databases of Stockholm County (VAL). Results:Dispensation of medications to the 12 766 patients analyzed in the study was high. Over 77% of patients used antihypertensives and antithrombotics, and 65%-68% used statins. After the intervention, no differences in medication dispensation were seen between the intervention and control centers, even after adjusting for potential confounders. Conclusions:A simple audit and feedback intervention directed toward physicians in primary care did not improve medication dispensation to ischemic stroke/TIA patients 18 months later. Any future audit and feedback intervention aimed at improving adherence to guidelines for secondary prevention in primary care should consider multiple and continuous reminders, the graphical appeal, and widening the recipients to include patients.

Planned primary health care asthma contacts during 12-year follow-up after Finnish National Asthma Programme: focus on spirometry

“…Evidence-based medicine and guidelines have improved the quality of health care, but still suboptimal adherence to care guidelines is a common worldwide problem seen not only with asthma 2-5 and chronic obstructive pulmonary disease [52][53][54] but also with other common chronic conditions, such as cardiovascular diseases and diabetes [55][56][57][58][59] . GPs generally deal with multimorbid patients.…”

Sex Differences in Stroke Care and Outcome 2005–2018

“…Similar findings have been presented in earlier Swedish and international studies. [37][38][39][40] An interaction between AF and statin prescriptions, suggests that women getting anticoagulation, are less likely to be prescribed statins. Still, in Sweden, statins are recommended after ischemic stroke, regardless of stroke cause including AF.…”

Thirty-six months recurrence after acute ischemic stroke among patients with comorbid type 2 diabetes: A nested case-control study

“…Hyperglycemia increases stroke patients' risk of death by 87% at 30 days, 75% at 1 year, and 41% at 6 years after stroke, respectively (Johnston and Beckman, 2019). In addition to being an independent predictor of stroke-induced death (Geary et al, 2019), hyperglycemia is a determinant of stroke recurrence (Hotter et al, 2019). Hyperglycemia augments brain injury through multiple potential mechanisms, including endothelial dysfunction, oxidative stress, increment of inflammatory response, and impaired fibrinolysis (Garg et al, 2006;MacDougall and Muir, 2011;Nogueira-Machado et al, 2011;Krinock and Singhal, 2021).…”
