The U.S. Center for Information Technology Leadership (CITL) conducted a study on The Value of Provider-to-Provider Telehealth Technologies. Assuming some specific healthcare settings such as emergency departments, correctional institutions, nursing homes and physician offices the cost-benefit analysis focused on three technology systems, i.e. store-and-forward, real-time video, and a hybrid model combining the first two.
The CITL study found that benefits outweighed costs for all three systems, but the research organization recommends the hybrid model as the most cost-effective one for the U.S. The report is available at citl.org.
