Background: Some earlier studies demonstrated an increased mortality risk attributed to delayed pulmonary embolism (PE) diagnosis. 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.
