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

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)
