Pioneering digital anticoagulation care

In 1997, our Medical Director, Dr Mark Sullivan, realised there must be a better way to manage anticoagulation clinics. Mark’s vision led to the development of INRstar, one of the first digital solutions for anticoagulation management.

This early digital breakthrough helped other clinicians like Mark to improve the safety and consistency of anticoagulation care by reducing manual errors and improving Time in Therapeutic Range (TTR) control. It also enabled a move from dependency on GP time to more efficient, nurse-led clinics supported by Health Care Assistants (HCAs) with INRstar’s role-based permissions.
