RESUMEN
INTRODUCTION: Blood pressure (BP) lowering reduces the risk of recurrent stroke after intracerebral haemorrhage (ICH). However, implementation of BP lowering in clinical practice in the UK is unknown. PATIENTS AND METHODS: We identified adults with first-ever incident ICH to quantify the proportion who survived >14 days after hospital discharge and were prescribed BP-lowering medication in a prospective, population-based, inception cohort study in the Lothian region of Scotland during June 2010-May 2012 and January-December 2019. After the first cohort, we analysed reasons for avoiding BP-lowering medication in a sample from the Lothian region of the Scottish Stroke Care Audit during January 2017-November 2017, which informed a quality improvement intervention that was implemented in the second cohort. RESULTS: After efforts to improve monitoring and lowering of BP amongst ICH survivors, there was an increase in the proportion of patients prescribed BP-lowering medication at hospital discharge between the first and second population-based cohorts (81/130 [62%] vs. 68/89 [76%]; P = 0.028). Compared with patients not prescribed BP-lowering medication at hospital discharge, patients prescribed BP-lowering medication presented with higher systolic BP (177 vs. 156 mm Hg, P = 0.002 and 180 vs. 149 mm Hg, P < 0.001, in the first and second population-based cohorts, respectively), and were more likely to have pre-morbid hypertension (85% vs. 33%, P < 0.001 and 72% vs. 29%, P < 0.001) and atrial fibrillation (35% vs. 4%, P < 0.001 and 26% vs. 5%, P < 0.034). CONCLUSION: In this population-based study, the proportion of patients with ICH who were prescribed BP-lowering medication at hospital discharge increased after a quality improvement intervention.
