2 NBN Telehealth Pilot Program CSIRO Telehealth Project Summary CSIRO Is lead organisation Six clinical partners and three industry partners Total project size $5.4m ($3.02m from DOHA/DBCDE Pilot Program) Six (6) Trial sites in Five (5) states and territories Focus on Chronic Disease Management (CDM) in the Community Six different models of care represented Trial duration 18 months ends 30 th Dec 2014

3 CSIRO NBN Telehealth Trial 6 Sites Townsville Penrith Greater Western Sydney Canberra and ACT Ballarat and the Grampians Launceston / Northern Tasmania Number of patients at each site 25 Test Patients 50 Control Patients Total 150 Test patients 300 Control Patients Trial Design Case Matched controls Before-After-Control-Impact (BACI)

4 Final Numbers Total enrolled N=287 Analysed ACT NSW QLD TAS VIC TOTAL Test Test Control Control

5 Key objectives of the CSIRO trial 1. Identify and model the impact of introducing telehealth services into existing models for the management of chronic disease in the community. 2. Develop robust statistical models to automatically risk stratify patients using questionnaires and vital signs data
