Are Virtual Doctor Visits Really Cost-Effective?
Consultations with doctors by phone or video conference appear to be catching on, with well over a million virtual visits reported in 2015.
The convenience of “telehealth” appeals to patients, and the notion that it costs less than an in-office visit would make it attractive to employers and health plans.
But a new study suggests that while telehealth services may boost access to a physician, they don’t necessarily reduce health care spending, contrary to assertions by telehealth companies.
The study, published Monday in the journal Health Affairs, shows that telehealth prompts patients to seek care for minor illnesses that otherwise would not have induced them to visit a doctor’s office.
Telehealth has been around for more than a decade, but its growth has been fueled more recently by the ubiquity of smartphones and laptops, said Lori Uscher-Pines, one of the study’s authors who is a policy researcher at the Rand Corp., a nonprofit think tank based in Santa Monica, Calif.
These virtual consultations are designed to replace more expensive visits to a doctor’s office or emergency room. On average, a telehealth visit costs about $79, compared with about $146 for an office visit, according to the study. But it found that virtual visits generate additional medical use.
The researchers found that only 12 percent of telemedicine visits replaced an in-person provider visit, while 88 percent represented new demand.
The researchers examined 2011-13 utilization data of 300,000 people enrolled in the Blue Shield of California Health Maintenance Organization plan offered by the California Public Employees Retirement System, which covers current and former state employees and their families. CalPERS’ Blue Shield HMO started offering telehealth services, available 24/7 to its beneficiaries, in April 2012.
The researchers focused on virtual visits for respiratory illnesses, which include sinusitis, bronchitis, pneumonia, and tonsillitis, among others.
While a single telehealth visit for a respiratory illness costs less than an in-person visit, it often results in more follow-up appointments, lab tests, and prescriptions, which increases spending in the long run. Liability concerns may prompt telehealth physicians to recommend that a patient go in for a face-to-face appointment with a doctor, the study notes.
Researchers estimated that annual spending for respiratory illnesses increased about $45 per telehealth user, compared with patients who did not take advantage of such virtual consultations.
Jason Gorevic, the CEO at Teladoc, the operator that provides telehealth services for CalPERS Blue Shield members, said the new study doesn’t square with Teladoc data showing the cost savings of telemedicine.
According to 2016 data, Gorevic said, only 13 percent of Teladoc visits represent new medical use. He noted that the Rand study uses older data, and that many things have changed since then — including the technology, the rate at which these services are being adopted and patient engagement.
“In fact, other more comprehensive studies — using six times the amount of claims data including the same population as the [Rand] study — have found tremendous value of telehealth, with consistently repeatable results,” Gorevic said. These other studies have shown that telehealth decreases overall health care spending, he said. But Uscher-Pines said the Rand findings were not surprising.
When Rand researchers studied retail clinics last year, they found that making access to health care more convenient triggers new use and additional costs. That study found 58 percent of visits to in-store clinics represented new use of medical services rather than a substitute for doctor office visits.
Yet the fact that telehealth services are more affordable per visit than a trip to a physician’s office shows that there is still a pathway to cost savings, Uscher-Pines said.
To achieve cost savings, telehealth services would have to replace costlier visits, the researcher said. Insurers could increase telehealth visit costs for patients to deter unnecessary use. Another way to increase the health system value of virtual doctor visits is to target specific groups of patients — such as those who often use emergency rooms for less severe illnesses. An emergency room visit costs an estimated $1,734.
“You could take these people in the emergency department and offer them this cheaper option. That would be a direct replacement,” Uscher-Pines said.
Gorevic said that a challenge for telehealth is engaging consumers, so the comparatively low fees provide a financial incentive.
“Because a telehealth visit is much cheaper than an in-person visit, the cost sharing should be reflective of that,” he said.
Some employers may offer telehealth as an added benefit for their employer-based health plan. There are some interesting figures regarding utilization rates.
Marcus Thygeson, senior vice president and chief health officer at Blue Shield, which also provides virtual doctor visits through Teladoc, in a statement said that “increased convenience can increase utilization, so overall healthcare costs may increase or stay the same. Blue Shield supports the use of telemedicine to improve access for both primary and specialty healthcare, especially in rural communities.”
The researchers noted several limitations to the Rand study. For example, researchers examined only one telehealth company and studied only visits for respiratory illnesses. In addition, the patients whose data were scrutinized had commercial insurance, and it is possible the use of telehealth would differ among people with government insurance, high-deductible plans or no insurance at all, the study said.
