“…In some cases assessment of image quality was done using scales, and in others it was not clear how the assessments were made. Image quality was considered lower for telemedicine compared with original radiographs in a few of the studies [26]–[28], [30]. Users in other studies expressed satisfaction with the telemedicine image quality [22], [29]–[32].…”

ObjectiveTo systematically review the literature on image-based telemedicine for medical expert consultation in acute care of injuries, considering system, user, and clinical aspects.DesignSystematic review of peer-reviewed journal articles.Data sourcesSearches of five databases and in eligible articles, relevant reviews, and specialized peer-reviewed journals.Eligibility criteriaStudies were included that covered teleconsultation systems based on image capture and transfer with the objective of seeking medical expertise for the diagnostic and treatment of acute injury care and that presented the evaluation of one or several aspects of the system based on empirical data. Studies of systems not under routine practice or including real-time interactive video conferencing were excluded.MethodThe procedures used in this review followed the PRISMA Statement. Predefined criteria were used for the assessment of the risk of bias. The DeLone and McLean Information System Success Model was used as a framework to synthesise the results according to system quality, user satisfaction, information quality and net benefits. All data extractions were done by at least two reviewers independently.ResultsOut of 331 articles, 24 were found eligible. Diagnostic validity and management outcomes were often studied; fewer studies focused on system quality and user satisfaction. Most systems were evaluated at a feasibility stage or during small-scale pilot testing. Although the results of the evaluations were generally positive, biases in the methodology of evaluation were concerning selection, performance and exclusion. Gold standards and statistical tests were not always used when assessing diagnostic validity and patient management.ConclusionsImage-based telemedicine systems for injury emergency care tend to support valid diagnosis and influence patient management. The evidence relates to a few clinical fields, and has substantial methodological shortcomings. As in the case of telemedicine in general, user and system quality aspects are poorly documented, both of which affect scale up of such programs.

“…With regard to the effect of image resolution on observer performance, published data seem to indicate that the results are task specific, and, to a large extent, study design seems to affect the results in a substantial manner. While results of some studies (16,22) seem to indicate that image resolution may be a statistically significant factor affecting observer performance, results of other studies (8,18) showed no significant differences for most detection tasks with images presented down to a resolution of 400 µm across a 35-cm field of view.…”

“…The effect of resolution and luminance on observer performance has been of interest in several areas, including but not limited to the field of diagnostic radiology (2,3,(15)(16)(17)(18)(19). Both theoretic and experimental results (2,19) have demonstrated that the human visual system is affected in a manner that is strongly dependent on luminance, frequency, and contrast.…”
