• The Trust introduced three new policies and a new chart for the administration of unfractionated heparin. • The Trust's new guideline for heparin administration is weight-based, with APTTR checks scheduled at 6 hours to allow for dose adjustment. • The guideline was updated to state that a Consultant Haematologist should be contacted for further advice if the APTTR is outside the expected range for patients at the extreme ends of weight ranges (<41kg and >90kg).
