Video visit examples by population and use.

Author	Population	Use of video or virtual consultation

One group did not use digital services at all. Digital services were used in the form of video for consultations or visits. The engagement in the use of technology in the study remained low.
Akhtar et al [44]	Emergency department (ED) patients with a sore throat	Video visits were carried out by using a video connection and a flashlight for examining the sore throat. In the study, video visits were judged easier to use for providers than patients.
Chao et al [46]	Surgical outpatients	Patients used video regularly for first visits in surgical specialties in response to the COVID-19 pandemic. The barriers to video visit usage were lack of necessities, such as private space, a stable connection, and a device on which to contact clinicians, and lack of an understanding of how to use a video platform.
Dayal et al [49]	Children with neurologic conditions	Video consultations were used by pediatric patients who received outpatient care from pediatric neurologists. Video consultations were associated with lower hospital use compared to in-person consultations.
Kong et al [53]	Patients visiting a rheumatology clinic	Patients of a rheumatology clinic used a video connection for clinic visits. The barriers to usage were older age, limited access to technology, and a short distance to the clinic.
Lin et al [59]	Patients with substance use disorders	Patients with substance use disorders used a video connection for clinic visits for psychotherapy and medication treatments. The use of a video connection was mostly associated with high patient satisfaction.
