Introduction: The clinical pathways are an approach to standardizing care process, which supports the use of clinical guidelines and protocols. The aim of this study was to investigate the association between the evidence-

based organization of pathways and quality management system in acute myocardial infarction (AMI) and stroke in Tehran Hospitals.

Methods: A random sample of 21 hospitals studied. The anonymous questionnaire of Quality management system index (QMSI) conducted through quality manager of these hospitals. The validity and reliability of the 40- item questionnaire obtained. 450 patient’s records in two acute conditions of acute myocardial infarction (MI) and stroke were reviewed with evidence-based organization pathway (EBOP) checklist. Data analyzed using descriptive statistics, Pearson correlation coefficient, ANOVA, T-Test, alpha Cronbach and multiple linear regression analysis. SPSS version 21 used to analyze the data. Results: There was a positive association between quality management system and evidence based organization pathway in (AMI) (β: PR>t: 0.014: and stroke (β: 0.654) . PR>t: 0.01, respectively. Hospital characteristics and QM did not 0.833), related.

Conclusion: We concluded that compliance of QM at the highest level of the hospital could improve the quality of special performance inpatient with two acute conditions in AMI and stroke. This study revealed that QM strategies were effective.
