Venous Thromboembolism in Multiple Myeloma

The overall goal of this project is to assess the impact of venous thromboembolism on patients with multiple myeloma as well as complete preliminary work to allow development of a clinical risk prediction model for venous thromboembolism in multiple myeloma. Thus far, I have developed a clinical tool to detect venous thromboembolism within administrative databases. Current use of ICD-9 codes to detect venous thromboembolism with databases yields poor accuracy with a positive predictive value averaging at 72%. Through development of a unique algorithm, I have improved accuracy to 91% thus allowing for reliable identification of venous thromboembolism. Given an accurate way of detecting VTE has been established, I am currently working on assessing the impact of venous thromboembolism on survival in multiple myeloma. Preliminary assessments show a 46% increase in mortality at 2 years in patients with multiple myeloma and venous thromboembolism versus those with multiple myeloma alone.
