Introduction: Deep vein thrombosis (DVT) is a significant cause of morbidity and mortality worldwide, accounting for substantial healthcare utilization. However, as management strategies have evolved, there is a critical need for current data on incidence, admission rates, and medical management of DVT in the ED setting.
Methods: This cross-sectional study analyzed ED presentations for DVT from 2016-2023 using the Cosmos database. Inclusion criteria comprised patients aged ≥18 years with an ICD-10 code for acute extremity DVT. Outcomes included incidence rates, admission rates, and anticoagulant prescriptions. Data were analyzed using descriptive statistics, and subgroup analyses were performed for upper and lower extremity DVTs.
Results: Out of 190,144,463 total ED encounters, DVT represented 368,044 cases (0.2%). Among these cases, 119,986 (32.6%) were admitted, with admission rates stable over the study period. Apixaban was the most prescribed anticoagulant (40.3%), followed by rivaroxaban (28.3%), enoxaparin (7.9%), warfarin (3.6%), and dabigatran (0.3%). Use of apixaban increased from 12.4% in 2016 to 56.2% in 2023. Lower extremity DVTs comprised 88.5% of cases, with a 32.1% admission rate, while upper extremity DVTs accounted for 11.7% of cases, with a 37.0% admission rate.
Conclusion: This study provides a summary of DVT presentations and management in United States EDs over an eight52 year period. The findings highlight stable incidence rates, reduced admission rates compared to historical data, and a significant shift towards the use of DOACs, particularly apixaban, for outpatient management. These trends underscore the importance of evidence-based practices 54 and ongoing research to optimize DVT management and improve patient outcomes.
