NHS Blood and Transplant developed Blood Assist to support healthcare professionals involved in the administration of blood components and the care of patients during transfusion. It provides an aide memoir for best practice in administration summarising key guidelines and recommendations from SHOT the British Society for Haematology and the Advisory Committee on the Safety of Blood Tissues and Organs. The app complies with NHSBT’s quality standards and has no associated information governance concerns as no patient data can be inputted.
