Our Story


Our journey began when Dr David Tralaggan witnessed a serious adverse patient outcome influenced by poor clinical documentation. David embarked on a personal odyssey to discover strategies to improve Australia’s clinical documentation.

Concurrently, Nicole Draper was charged with improving clinical documentation in a large metropolitan private hospital.


Nicole Draper successfully established one of the first clinical documentation improvement (CDI) programs in Australia.

Dr David Tralaggan incorporated Clinical Documentation Improvement Australia (CDIA).


Dr David Tralaggan and Nicole Draper combined forces and entered a partnership due to their mutual passion for CDI.

Within the year, CDIA secured partnerships with hospitals across all of Australia’s east coast states.


We continued to grow through partnerships with the second largest private hospital network in Australia and the largest private hospital network in Western Australia.


We completed major CDI projects in every state in Australia.

We spoke at multiple international conferences, including the IFHIMA Congress in the UAE, the ACDIS Conference in the USA and the Saudi Patient Safety Centre Conference in Saudi Arabia.

The number of clinicians CDIA educated grew to more than 7000.


We went international, partnering with the largest public hospital in New Zealand.
