Therefore, we mainly aimed to determine the predictors of diagnostic delays and the effect of delayed diagnosis on mortality. Methods: We prospectively studied 756 consecutive patients admitted with PE between March 2007 and September 2017. The delayed diagnosis was defined as (1) patient presenting > 7 days after onset of symptoms, (2) diagnosis takes > 24 hours upon arriving in the ED, or (3) undergoing coronary angiography before establishing PE diagnosis. Results: A total of 127 (16.7%) patients met the delayed group’s criteria. Heart failure (OR= 2.257, 95% CI: 1.130-4.508, P= 0.021), diabetes mellitus (OR= 1.568, 95% CI: 0.996-2.469, P= 0.052), and precordial T wave inversions (OR=2.559, 95% CI: 1.649-3.970, P< 0.001) were linked to higher rates of delayed diagnosis, while hemoptysis (OR=0.254, 95% CI: 0.059-1.087, P= 0.065) and hemodynamic instability (OR= 0.434, 95% CI: 0.168-1.123, P= 0.085) negatively correlated with it. Delayed PE diagnosis did not significantly impact the overall survival during the follow-up. The unadjusted and adjusted mortality hazard ratio for delayed diagnosis were 1.198 (95% CI: 0.758- 1.894, P= 0.439) and 1.215 (95% CI: 0.762- 1.939, P=0.413), respectively. Older age, heart failure, and hemodynamic instability increased the risk of death (p<0.001). Conclusion: Hemoptysis, hemodynamic instability, diabetes mellitus, heart failure, and T wave inversions in precordial leads were the independent predictors of delayed diagnosis. Delayed PE diagnosis did not increase the patients' mortality rates.
