Assessment of patients' acceptance of and satisfaction with teledermatology

Teledermatology refers to the use of information and communication technologies (such as videoconferencing or transmission of digital images) to enable the practice of diagnostic dermatology between participants separated by geographic distance. The objective of this study was to critically review the quality of evidence about patient satisfaction with teledermatology applications. Sample size, reporting of validity and reliability, used instrument and its underlying constructs were determined for all studies where information was available. Fourteen studies were identified, five refer to store-and-forward applications, the remaining ones describe video-based systems. The systematic review demonstrated that methodological deficiencies in the published research impact the generalizability of findings. The two types of teledermatology (video-based and store-and-forward) require different satisfaction instruments as they are based on different contexts of care delivery, with video-mediated communication being key in the former and patients' absence from the diagnostic process in the latter mode of care delivery.
