Primary Research Interests


Adj. A/Prof Mitchell has devoted the past two decades developing programs to improve fragility fracture care and prevention worldwide, including global, regional and national initiatives to implement the Fracture Liaison Service (FLS) model of care. He has published and presented extensively on the implementation of FLS, and was a co-author of the 2012 International Osteoporosis Foundation (IOF) World Osteoporosis Day Report on the IOF Capture the Fracture® Program. In 2016, Adj. A/Prof Mitchell was awarded the IOF President’s Award in recognition of his personal contribution to the organisation’s global activities.  

In 2007, Adj. A/Prof Mitchell served as a member of a multidisciplinary group that established the UK National Hip Fracture Database (NHFD). The NHFD has provided a mechanism to benchmark care provided by UK hospitals against national quality standards and has become the world’s largest continuous audit of acute hip fracture care and secondary prevention, documenting the care of more than 800,000 patients to date.  

After emigrating from the UK to New Zealand in 2011, Adj. A/Prof Mitchell contributed to the establishment of the Australian and New Zealand Hip Fracture Registry (ANZHFR). As of March 2023, all 22 of New Zealand’s 22 hospitals, and 82 of Australia’s 96 hospitals have contributed 20,216 and 72,968 records to the ANZHFR, respectively.  

In 2012, Adj. A/Prof Mitchell was invited to join the Board of Trustees of Osteoporosis New Zealand (ONZ), for which he served as Board Chair from 2014 to 2018, during which significant progress was made with implementation of Osteoporosis New Zealand’s strategy, BoneCare 2020. In 2017, a national multi-sector effort culminated in the establishment of the Live Stronger for Longer program supported by three government agencies – the Accident Compensation Corporation, Health Quality and Safety Commission New Zealand, and the New Zealand Ministry of Health.
