NASA Develops VTE Risk Score Algorithm for Astronauts

NASA's Office of the Chief Health and Medical Officer (OCHMO) Launches Working Group to Address VTE Risks in Astronauts

In a proactive effort to ensure the health and safety of astronauts, NASA's OCHMO established a working group in April 2026 to review and discuss the latest developments in venous thromboembolism (VTE) research. The working group was formed in response to updated case information and additional data collected on altered blood flow status within a specific cohort of astronauts. This new information has highlighted the need for continued research and clinical activities to mitigate the risk of VTE during spaceflight.

As part of its mission, the working group will focus on reviewing the progress of ongoing research and clinical activities aimed at reducing VTE risks in astronauts. This will involve examining the latest findings from studies on altered blood flow status, as well as exploring new strategies for preventing and treating VTE in space. The working group will also provide recommendations for future research directions and clinical interventions to ensure that NASA's astronauts receive the best possible care and protection against VTE.

The establishment of this working group underscores NASA's commitment to prioritizing the health and well-being of its astronauts. By staying at the forefront of VTE research and clinical activities, NASA can continue to minimize the risks associated with spaceflight and ensure that its astronauts remain safe and healthy during their missions.
