Jennett set up a prospective computerised data bank to collect the features and outcome of head injuries. Data was compiled from Glasgow, the United States, and the
Netherlands over a long period and led to a series of papers in the 1970s, the introduction of the near universally adopted
Glasgow Coma Scale (GCS) with
Graham Teasdale, and the
Glasgow Outcome Scale with Bond. In 1972 working with Dr Plum of America, Jennett published
The Persistent Vegetative State – defining a condition and coining a phrase which remains in widespread use today. His work with the Glasgow-based Neuropathologists Adams and Graham significantly reduced mortality and disability. Many international collaborative studies followed, comparing outcomes after different severity of injury and with alternative therapeutic regimes. In 1976 there was furore over a
BBC Panorama Programme which questioned the criteria for the establishment of
brain death in potential organ donors. Jennett was in demand as a speaker and in the UK contributed to medical panels and was called to Court as an expert witness, most notably for the
Tony Bland case. Jennett was Dean of Medicine at Glasgow in the 1980s. He worked with Barbara Stocking and Chris Ham of the
King's Fund to establish a series of Consensus Conferences to deal with the appropriate use of high-cost medical technology. He was President of the International Society for Technology Assessment and in 1984 he published
High Technology Medicine: Benefits and Burdens followed a series of BBC talks
Doctors, Patients & Responsibilities which were widely praised. In 1988 he developed
deep-vein thrombosis (DVT) which he blamed on the cramped seating on an aircraft. Along with colleagues who had similar experiences, he published a short paper in
The Lancet. This was the first use of the term "economy-class syndrome". Jennett retired in 1991. In his later years, he was named
Commander of the Order of the British Empire (CBE) and received an honorary doctorate from
St Andrews University. His continuing work included a 2002 monograph,
The Vegetative State, and his final publication appeared in the
British Journal of Neurosurgery in 2008. He died a few weeks after that final publication, having been diagnosed with
multiple myeloma five years earlier. His wife Sheila and his three children survived him. ==References==
