Chadwick's study in the US will focus on effective transdisciplinary work within health systems.
"The US has a highly legislated and litigious healthcare environment, yet there are systems which nevertheless achieve effective transdisciplinary work," he said.
"What I want to learn is how this is achieved, and in turn, how I can bring that back to New Zealand."
As well as Chadwick's fellowship for 2019/2020, other BOPDHB recipients include Te Kaha GP Emily Gill in 2017/18, chief executive Helen Mason in 2014/15 and physician Dr George Gray in 2013/14.
Emily Gill has recently returned from her fellowship, where she looked at the role health information technology can play for those suffering chronic conditions, especially those living in rural areas.
"People who live in rural areas have poorer health than their urban counterparts, and for those with multiple, complex medical needs, this is compounded by the challenge of co-ordinating care across multiple providers and practice settings," Gill said.
"To provide co-ordinated care, health information needs to be frequently transferred across settings such as primary care clinics, acute care hospitals, and community health services. That can prove challenging technologically and I wanted to explore the US experience of this, especially for those working with rural patients."
Gill said her time in the US had proved invaluable and she looked forward to using what she had learned in her work in the Eastern Bay of Plenty.
