This app was designed and created by Dr Manos Nikoloussis, Dr L Khalil and Dr. V Murray at the Heart of England NHS Foundation Trust. Many other consultant colleagues and trainees in Haematology contributed to the completion of this app. The purpose of this app is to help colleagues involved in the initial care of potential haematological conditions in order to facilitate patient diagnosis and patient flow within Heart of England NHS trust. Haematological diagnostic pathways and treatments are constantly changing. The app aims to discuss haematological diagnostic pathways and management followed at a tertiary Haematology centre in the UK and implement critical diagnostic tool earlier in the patient pathways.
