Dr Mitchell took the results on the road and passed them on to Plunket nurses. Within a few years, death rates dived.
"I guess there's a huge satisfaction in realising that in New Zealand, we've probably saved about 3000 babies from dying with the interventions we've put in place," he told the Herald. "But there's also an air of frustration ... if all of the messages were taken up, then the 50 deaths occurring each year currently would probably drop to only six."
He has paid tribute to the families who lost babies for having the courage to talk to researchers. This had been immensely helpful in guiding the life-saving projects.
His most recent research has been in the area of babies and bed-sharing. This work has encouraged the use of pepi-pods, which allow parents to safely bed-share with babies.
Dr Mitchell, Cure Kids Professor of Child Health Research, has been showered with awards recognising his stellar achievements, including the Beaven Medal.
