 To estimate the potential for cadaveric solid organ donation from brainstem-dead donors, Bird designed UK's first confidential audit of all deaths in intensive care units which revealed that relatives’ refusal –rate (then 30%, since risen to 40%), not doctors’ failure to ask, was the fundamental problem.Bird led the MRC Biostatistical Initiative in support of AIDS/HIV studies in Scotland (1990–1995), which included projection of Scotland's cases of severe immunodeficiency (so-called CD200 cases) and HIV epidemiological studies in prisons, both with co-investigator, clinical immunologist Dr A. Graham Bird.Bird's work at the interface of public health and other jurisdictions continued.
