Summary

This study looks at whether people with a moderate-risk blood clot in the lungs can be safely treated at home instead of staying in the hospital. About 568 adults will be randomly assigned to either go home early or receive standard hospital care. The goal is to see if home treatment is just as safe and improves quality of life.
