[Evolution of the degree of disease knowledge in subjects who have suffered an ischaemic stroke].

Abstract

INTRODUCTION\nThe delay in seeking medical care in patients who suffer a cerebrovascular disease (CVD) event depends, largely, on knowledge of the disease. Our aim is to study the evolution of the knowledge of patients admitted to hospital due to an ischaemic stroke.\n\n\nPATIENTS AND METHODS\nA structured interview was used to determine the level of knowledge of CVD (terminology, risk factors, symptoms and attitude) of patients admitted due to an ischaemic stroke without language impairment or cognitive impairment in two distinct time periods: January 2011 and December 2013 (n = 295), and October 2015 and December 2016 (n = 325).\n\n\nRESULTS\nBetter knowledge of the disease was observed over time, both in the number of terms recognised - 4.1 (standard deviation: 2) vs. 4.8 (standard deviation: 1.7); p < 0.001 - and in a good knowledge of symptoms (more than three factors and less than two distractors) (56.6 vs. 69.8%; p < 0.001). The proportion of patients who called the emergency services directly was significantly higher (17.3 vs. 24.6%; p = 0.003), as was the recognition of the term stroke (51.9 vs. 74.5%; p < 0.001). There was no difference in the degree of knowledge of risk factors. Improvement in knowledge did not translate into a decrease in the delay between symptom onset and arrival at the hospital.\n\n\nCONCLUSION\nDespite improved knowledge of CVD, further efforts still need to be made to improve attitudes towards CVD and reduce the delay prior to hospital arrival.
