Access to a patient portal can increase engagement in outpatient visits by patients with diabetes and those with multiple complex chronic conditions. The study showed that portal use was associated with significantly fewer emergency room visits and preventable hospital stays for patients with multiple complex conditions. By increasing patient office visits, a portal could potentially help clinicians address unmet clinical needs and reduce health events that lead to emergency and hospital care. The observational study compared visit rates for 165,000 patients with and without portal access in a large healthcare system that implemented a patient portal.
