The use of telemedicine has broadened as technology that both restores continuity of care during disruptions in healthcare delivery and routinely provides primary care alone or in combination with in-person care. During the Covid-19 outbreak, the use of telemedicine as a routine care modality further accelerated.

A review of scientific studies that used telemedicine to provide care from December 2019 to December 2020 is presented. From an initial set of 2,191 articles, 36 studies are analyzed. Evidence is organized and evaluated according to the country of study, the clinical specialty, the technology platform used, and satisfaction and utilization outcomes.

Thirty-one studies reported high patient satisfaction scores. Eight studies reported satisfaction from both providers and patients with no uniformly accepted assessment instrument. Eight studies conducted a descriptive analysis of telemedicine use and patient adoption patterns. Less than one-third of studies were controlled before/after studies. Most studies were conducted in the USA followed by Europe.

Reported satisfaction rates are high, consistent with previously documented research, whereas utilization rates increased significantly compared with the prepandemic period. Future work in developing standardized uniform assessment instruments, embedded with each telemedicine system, would increase versatility and agility in the assessment, boosting statistical power and the interpretation of results.
