The Children's Medical Charity was set up in 1982 in the Department of Experimental Chemical Pathology in the Vincent Square Laboratories of Westminster Hospital. Funding cuts were a persistent problem, most of the material being concerned with various attempts to raise funds and place the research and diagnostic work of the charity on a firm basis. Diabetes, vitamin B12 metabolism and protein absoprtion were among the research interests of the charity. In 1986 it was floated as an Investment Trust, launched in July 1986. In 1988, further Government decisions proposed the closure of Westminster Hospital and Westminster Children's Hospital and their replacement by a single hospital in Fulham Road. Hodgkin agreed to become a Scientific Adviser to the charity in 1983. She took part in conferences and Open Days. In 1988, under the threat of closure, she agreed to become a Patron of the Westminster Hospitals Development Fund.
