A cross-sectional study of factors related to traditional Chinese medicine use for hospitalized acute coronary syndrome patients in China's level 2 hospitals / 中华心血管病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the current status on traditional Chinese medicine (TCM) use for hospitalized acute coronary syndrome patients in China's level 2 hospitals, and to explore associated factors of TCM use for these patients.</p><p><b>METHODS</b>This survey was performed in 102 level 2 hospitals from 15 provinces or autonomous region in China. Patients admitted to these hospitals with acute coronary syndrome during September 2011 to May 2012 were eligible for this study. Information on TCM use was obtained from their medical records. Chi-square test and logistic regression analysis were used to explore the related factors of TCM use in these patients.</p><p><b>RESULTS</b>We recruited 5 432 acute coronary syndrome patients in this study, TCM was applied to 3 503 patients (64.5%). Multivariable logistic regression showed that pre-hospital TCM use was positively related with in-hospital TCM use (OR = 2.08, P < 0.01) , while pre-hospital use of 4 medicines recommended by the guidelines(including aspirin/clopidogrel, β acceptor blocker, stain and angiotensin converting enzyme inhibitor/angiotensin converting enzyme receptor blocker ), being a smoker and diagnosis of myocardial infarction rather than unstable angina at hospital discharge were negatively related with in-hospital TCM use (the ORs were 0.58, 0.78 and 0.71, respectively, all P < 0.01). The TCM use varied significantly between regions. Taking southwest region as a reference, the ORs varied between 2.98-13.37 (all P < 0.01) in eastern China, south China, central China, north China, northwest and northeast regions.</p><p><b>CONCLUSIONS</b>TCM is widely used in hospitalized acute coronary syndrome patients in China's resource-constrained level 2 hospitals. Pre-hospital TCM use is positively correlated with in-hospital TCM use for these patients.</p>
