ABSTRACT
INTRODUCTION: Rapid diagnosis and treatment of deep vein thrombosis and pulmonary thromboembolism reduce mortality and morbidity. The aim of this study is to investigate delays in treatment of deep vein thrombosis and pulmonary thromboembolism and related factor in a developing country. MATERIALS AND METHODS: We prospectively investigated 353 patients with diagnosis deep vein thrombosis and/or pulmonary thromboembolism in Urmia, Iran. We recorded dates of symptom onset, initial visit by a clinician, initiation of treatment, and confirmation of diagnosis. We also analyzed relation with some factors. RESULTS: The mean interval from symptoms onset to initiation of treatment was 4.70 days, 89% of this interval was between onset of symptoms to first medical evaluation (mean= 4.19 days). Mean time from onset of symptoms to confirmation of diagnosis was 6.29 days. Of 353 patients with venous thromboembolism 185 (52.4%) visited by a physician within two days of onset of symptoms and 168 (47.6%) patients after two days. Factors that was associated with earlier seeking with p value < 0.05 were pulmonary thromboembolism patients earlier than deep vein thrombosis, higher education, recent surgery, presence of cast, entire leg swelling. There was no association between age, gender, number of symptoms, and presence familial history of venous thromboembolism (all p value > 0.05). The delays time from first visit to final diagnosis was significantly shorter in patients with high probability score. CONCLUSION: Most patients with venous thromboembolism received anti-coagulation and diagnosis with delay. The main cause of delay is related to patient's delays. There is a need to improve people awareness about venous thromboembolism and to develop strategies to reduce delays.
