Telestroke cost effective for hospitals

Researchers have found that using telemedicine to deliver stroke care, also known as telestroke, appears to be cost-effective for rural hospitals that do not have an around-the-clock neurologist, or stroke expert, on staff. The research, published today in Circulation: Cardiovascular Quality and Outcomes, is intended to help hospital administrators evaluate telestroke.

In telestroke care, the use of a telestroke robot allows a patient with stroke to be examined in real time by a neurology specialist elsewhere who consults via computer with an emergency room physician in the rural site.

"Previous studies have demonstrated that a hub-and-spoke telestroke network is cost-effective from the societal perspective - we can assess medical services, like telemedicine, in terms of the net costs to society for each year of life gained," says Bart Demaerschalk, M.D., director of Telestroke Program, and co-author of the telestroke cost effectiveness study. "However, to date the costs and benefits from the perspectives of network hospitals have not been formally estimated."

Contrary to a common perception that a telestroke referral network poses a substantial on hospitals, the study revealed that it is likely to save hospitals money and also improve by enabling patients to be discharged sooner. "The health economic results from an earlier study conducted from the societal perspective convincingly demonstrated that telestroke was cost effective compared to the usual model of care," says Dr. Demaerschalk. "It's a relatively small amount of money, comparatively, telestroke costs a couple thousand dollars more to save quality years of life—so it's a bargain really."

The Circulation study estimates that compared with no network, a telestroke system of a single hub and seven spoke hospitals may result in the use of more clot-busting drugs, procedures and other stroke therapies, more discharged home independently, and despite upfront and maintenance expenses, a greater total cost savings for the entire network of hospitals.

Using data from Mayo Clinic and the Georgia Health Sciences University telestroke networks, the research model estimated that every year, compared to no network, 45 more patients would be treated with intravenous thrombolysis and 20 more with endovascular stroke therapies – leading to 6.11 more independent patients discharged home. This represents more than $100,000 in cost savings for each of the participating each year, according to the study.

"If the costs associated with the technology are reduced or if reimbursement opportunities increase we will recognize that this treatment method may, in fact, save even more money," Dr. Demaerschalk says. "The upfront costs associated with setting up the telestroke technology and managing the network organization are quickly offset by the financial gains that result from a higher proportion of patients receiving and the reduced stroke-related disability and subsequent reduced need for rehabilitation, nursing home care and assistance at home."

The results of this economic research have implications on the assignment of financial responsibility between hub and spoke hospital partners. For instance, in a network that is principally designed to aid spoke hospitals' capacity to effectively assess, treat, and admit more patients with stroke, it is the spoke hospitals which benefit economically - and it then makes sense that the spoke hospitals should contribute to financing the telestroke network system.
