State of The Nation 2020 Our State of the Nation report illustrates current clinical practice regarding the care of people with genetic haemochromatosis (GH), across the United Kingdom. In July 2019, Haemochromatosis UK initiated a survey (under the Freedom of Information Act) of 176 NHS acute/secondary care trusts and health boards in England, Wales, Scotland & Northern Ireland. This survey attempts to better understand current clinical practice regarding the care of people with genetic haemochromatosis (GH), across the United Kingdom. It follows earlier surveys undertaken in 2016 and 2018, which illustrate trends in genetic haemochromatosis clinical practice over the past 4 years. This report was co-authored by : Gerri Mortimore RGN; NMP, Practice Teacher; MSc Advanced Practice; BA (Hons) Health Studies, PgCert (IPPE).
