A growing number of patients seem to be attracted by the convenience of connecting with their doctor online. And doctors are also finding it useful as health services come under pressure from growing and ageing populations.
A significant portion of the patients doctors see daily are quick follow-ups of well-managed, long-term conditions, lab results, or script renewals and these can be addressed through tele-consultations.
It is a point echoed by Luke Buhl-Nielsen, from Swedish telemedicine app KRY (which uses the name LIVI outside Scandinavia).
“In Sweden, up to 45 percent of the volume that comes into general practice can be dealt with digitally,” he says. And virtual visits are roughly two-thirds cheaper to provide than in-person visits, research suggests. Doctor shortages is a growing problem around the world.
The US could have up to 50,000 fewer than it needs by 2030, research firm IHS Markit believes. In Asia, the doctor shortage is fuelling the rapid rise of telehealth apps such as Halodoc, Doctor Anywhere, and Ping An Good Doctor.
Private equity firms and venture capitalists are piling in to the sector, investing billions, as healthcare providers respond to the app-savvy, more consumer-focused generations.
Nearly two-fifths of Americans aged 22-38 now seek routine medical services virtually these days, says a digital health survey from consultancy firm Accenture.
And this generation demands more convenient appointment times and a better service than that enjoyed by their elders.
The number of virtual visits to the doctor in the US will reach 105 million by 2022, up from 23 million in 2017, says IHS Markit.
Telemedicine has particularly taken off in Nordic countries, and is popular with women in Turkey, where birth control is coming under attack, according to analytics firm App Annie.
Employers are also cottoning on to the benefits of telemedicine as a workplace perk. In the US, retail chain Walmart is offering employees doctor’s appointments for $4 if they use a telemedicine service.
But there are challenges integrating telemedicine into healthcare systems, like Britain’s or Canada’s, that are paid for primarily from taxation.
In the UK, for example, National Health Service GP surgeries receive a fixed amount of money for each patient on their books.
The patients with easily treatable conditions effectively subsidize those with more complex conditions who require more care and attention.
So the concern is that telemedicine services could simply ‘cherry pick’ the younger, healthier patients, leaving bricks-and-mortar surgeries with less money to treat those patients who are more expensive to treat.
And while chatbot-based health apps, such as Babylon, are also proving useful for initial triage or assessment of simple patient conditions, there are some concerns about how accurate the artificial intelligence (AI) underlying such chatbots really is.
Dr. Annette Neary, a former NHS consultant now based in Galway, Ireland, says: “Chatbot algorithms frequently ask overly broad questions and often come up with bizarre diagnosis options.”
For example, she recently input symptoms of a man having a heart attack, and the AI came up with “panic attack” as a diagnosis.”Another one for sepsis came up with gonorrhoea,” she says.
So while many doctors think you can not beat a face-to-face consultation, there are plenty of other benefits if that face is on a smartphone or computer screen.
