How 'telehealth' may replace doctor visits in major cities amid a shortage of physicians

If you need to see a doctor, you'd better plan ahead. A 2017 survey found 24 days was the average wait time in 15 of the largest cities to schedule a physician appointment.The long waits are a result of a growing shortage of primary care physicians, along with an aging population requiring more health care. But you can jump that line -- if you're willing to go online for your medical visit. Major health care players like, UnitedHealth, Aetna and Kaiser Permanente, are increasingly using virtual care or telehealth for primary care appointments and follow-ups. Another option is "virtual visit" via a smartphone app.
