IMPROVE VTE and bleeding risk calculators

This tool implements IMPROVE risk nomograms for bleeding and clinically evident acute venous thromboembolism using two risk calculators: The IMPROVE Bleeding Risk Model: Provides an estimate of the probability of major or clinically important in-hospital bleeding from the time of hospital admission up to 14 days following admission. Model risk factors were selected based on risk factors that were known (or that could be reasonably estimated) at the time of hospital admission. The cumulative incidence of major and non-major but clinically relevant in-hospital bleeding within 14 days of admission was 3.2%. The IMPROVE VTE Risk Model: Provides an estimate of the probability of clinically evident acute venous thromboembolism from the time of hospital admission to discharge, based on risk factors that are known (or that can be reasonably estimated) at the time of hospital admission. The cumulative VTE incidence from admission to 3-month follow-up was 1.0%, with 45% of VTE events occurring post-discharge. Please note that these risk calculators are a beta version. A separate validation test of these models is under development.
