Abstract 137: Post-Stroke Blood Pressure Control and Follow Up Care in Real-World Setting

Abstract

Introduction: Within 5 years of a stroke, approximately 25% of patients will have a recurrent event. Blood pressure (BP) reduction can reduce this risk; every 10 mmHg decrease in systolic BP is associated with a 20% risk reduction. Despite this benefit, 50% of patients with hypertension remain uncontrolled after a stroke. Reasons for poor control may be related to poor post-stroke follow up care. We aim to quantify post-stroke BP control and follow up in a large health system. Methods: We performed a retrospective analysis of patients with stroke admitted to Yale New Haven Health System (YNHHS) between 2013-2021. YNHHS has 5 hospitals and a large outpatient network. Eligible patients included those who received primary care within YNHHS, were discharged alive, and not on dialysis. We analyzed patient features, time to outpatient encounter, and vital signs. The primary outcome was uncontrolled BP (>140/90) obtained during the office visit closest to and before 6 months from the date of discharge. Results: During the study period 12,561 patients were admitted with stroke to YNHHS. After exclusions, the final cohort was 2,867 patients. Among these patients, 48 % were male, 65% non-Hispanic White, 22% non-Hispanic Black, 9% Hispanic, and 4% other. Mean (standard deviation) age was 68 (12) years. Approximately 25% of patients had uncontrolled BP. When the updated ACC/AHA (2017) BP goal (<130/80) was applied, the amount of patient with uncontrolled BP increased to 52%. After 6 months, 318 (11%) had no visit with a medical provider, 250 (9%) patients had 1 follow up visit, and 2,299 (80%) patients had >2 follow up visits. The median (interquartile range [IQR]) number of days to first visit with a PCP or neurologist was 30 (10-97) days and 45 (27-99) days, respectively. The median (IQR) number of visits with either a PCP or neurologist was 0 (0-2). Conclusion: Among patients with recent stroke, more than half do not achieve BP control per current guidelines. The majority of patients do not engage with a PCP or neurologist within 6 months following a stroke, even though they have an established provider within the system. Gaps in follow up represents a notable opportunity for improving post-stroke care.
