A Brief History of Telehealth

1900 – 1950 Radio and telephone

1960s Satellite, microwave, astronaut telemetry, tests of video communication

1970s – 1980s ISDN lines, early telehealth video trials

1990s Internet, PCs, video consultation over ISDN grows, early trials of home telehealth

2000s Broadband, mobile phones, social media: expansion of home telehealth and chronic disease management

2010s Smart phones, tablets, fibre, data & video integration

2015 Mobile apps, wearable devices, larger home trials

Next??? Smart homes, patient portals, large scale take-up of virtual consultations, haptic communication

Does Telehealth Work?

• Mental Health: telehealth as effective as in-person for assessment, psychological treatments or case management

• Acute stroke: increases access to thrombolysis

• Heart failure: home monitoring decreases mortality

• Cardiac rehabilitation: greatly increases access

• Diabetes: improves HbA1c

• Overall: reduces hospital admissions and ED visits

• BUT: many areas of service delivery still in the early trial and feasibility test stages

Telehealth delivering improved regional outcomes in Australia

Began 12 years ago; been statewide for 5 years

Includes a telephone hot line, ECG interpretation, Point of care testing, TNK delivery, clinical guidelines, video consulting … they have halved the death rate for acute cardiac presentations in rural South Australia; it is now the same as the urban rate.

11

Is Telehealth Cost-Effective?

It Depends!!!

• Telehealth is almost always cost-effective from the societal perspective

• Variable from the health services perspective: less costly if it is replacing PAID TRAVEL ie outreach services or patient transport schemes

• Home care: most studies have found better outcomes for increased cost; moving feast as technology prices crash. Watch this space.
