Virtual Supervision in Graduate Medical Education: A Systematic Review.

Despite the increased use of telemedicine, the evidence base on virtual supervision in graduate medical education (GME) is not well described. To systematically review the impact of virtual supervision on trainee education, patient care, and patient satisfaction in Accreditation Council for Graduate Medical Education (ACGME)-accredited specialties. Two databases (PubMed, EMBASE) were searched from database inception to December 2022. Inclusion criteria were peer-reviewed, full-text, English-language articles reporting the use of virtual supervision in GME in ACGME-accredited specialties. Exclusion criteria were studies involving direct supervision, supervisors who were not credentialed physicians, or non-GME trainees. Two investigators independently extracted data and appraised the methodological quality of each study using the Mixed Methods Appraisal Tool (MMAT). The reporting of this systematic review was guided by the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement. Of 5278 records identified, 26 studies met the eligibility criteria. Virtual supervision was predominantly utilized in operating rooms and inpatient settings, facilitating clinical examinations or surgical procedures through videoconferencing software in specialties such as dermatology, neurosurgery, and orthopedics. However, some studies reported technical challenges that hindered effective teaching and communication. Based on self-reported surveys, supervisor and trainee satisfaction with virtual supervision was mixed, while patient satisfaction with the care was generally high. The MMAT ratings suggested limitations in sampling strategy, outcome measurement, and confounding factors. Virtual supervision was applicable to various specialties and settings, facilitating communication between supervisors and trainees, although there were some technological challenges.
