<qa>  What is the potential solution with demonstrated effectiveness in other vulnerable populations?Telemedicine is a potential solution with demonstrated effectiveness in other vulnerable populations. Previous work by members of this research team has shown that telemedicine is an effective health information technology solution to address similar challenges in multiple vulnerable populations, demonstrating both improved access to care and reduced ED visits. The existing telemedicine program in Rochester, Health-e-Access HeA, has been both successful and sustained, and well accepted by all key stakeholders including patients, families, clinicians, and insurers. This existing program, combined with the experience and multidisciplinary expertise of the investigators research team, creates a unique opportunity to 1 develop a model of care that leverages this technology to improve geriatric acute care, 2 evaluate this model through a prospective cohort study, and 3 identify key barriers and drivers of implementation to promote dissemination.
