In 1929, she was appointed clinical examiner in medicine at Queen"s University, the first woman to hold the post. In 1945, she was appointed to the Advisory Committee for the Belfast Area under the Unemployment Acting (Northern Ireland), 1934, while in 1949, she was appointed to the Irish National Health Council. Hickey was nominated by Roman Catholic graduates of Queen"s University as their candidate in the Queen"s University, Belfast by-election, 1948, but was easily defeated by Samuel Irwin.
She was again nominated for the Queen"s University Belfast constituency at the Northern Ireland general election, 1949 and was elected this time.
While there, she was viewed as a potential ally by the Anti-Partition of Ireland League MPs. Hickey was re-elected in 1953 but stood down in 1958.
A committee of the Parliament of Northern Ireland concluded that her Advisory Committee post constituted an office of profit under the crown, even though she never claimed or received any remuneration. This officially invalidated her elections.
She became a member of the Board of Governors and was later President of the Ulster Medical Society. She served as an independent Member of Parliament.
