Telementored ultrasonography: a narrative review

ABSTRACT BACKGROUND: Teleradiology consists of electronic transmission of radiological images from one location to another, including between countries, for interpretation and/or consultation. It is one of the most successful applications of telemedicine. Combining this methodology with ultrasound (called telesonography) can accelerate the process of making diagnoses. Despite this rationale, the quality of the evidence about the effectiveness and accuracy of teleradiology remains unknown. OBJECTIVE: To review the literature on the evidence that exists regarding use of telemedicine for ultrasound in situations of synchronous transmission. DESIGN AND SETTING: Narrative review conducted within the evidence-based health program at a federal university in São Paulo (SP), Brazil. METHODS: A search of the literature was carried out in April 2020, in the online databases MEDLINE, EMBASE, Cochrane Library, Tripdatabase, CINAHL and LILACS, for original publications in all languages. The reference lists of the studies included and the main reviews on the subject were also evaluated. RESULTS: We included ten studies that assessed procedures performed by different healthcare professionals, always with a doctor experienced in ultrasound as a distant mentor. Among these, only one study assessed disease diagnoses in relation to real patients. CONCLUSIONS: Despite the promising position of telesonography within telemedicine, no studies with reasonable methodological quality have yet been conducted to demonstrate its effectiveness.

An evaluation of the awareness, perceptions, and practice of ultrasound and the use of telesonography among obstetrics and gynecologic sonologists in the Philippines during COVID-19 pandemic / Philippine Journal of Obstetrics and Gynecology

Background@#Major changes in the practice of medicine have been adopted due to the COVID-19 pandemic and have not spared the practice of ultrasound among obstetrician–gynecologists, considered to have higher risk due to unique attributes of an ultrasound examination. @*Objectives@#This study evaluated the awareness, attitudes, perceptions, and practices of the obstetric–gynecologic sonologists in the country during the pandemic, including the use of telesonography.@*Methodology@#A descriptive, cross-sectional survey was conducted through a self-administered, structured questionnaire using an online survey software. @*Results@#There were 120 respondents with postresidency training in ultrasound (54.2%) or in maternal and fetal medicine (43.3%), practicing in different regions, and mostly with teaching affiliations (56.7%). Most are aware of the guidelines on the practice of ultrasound this pandemic and they perceived themselves to be especially vulnerable to the infection. They admitted having feelings of stress, sadness, and depression, and their concerns centered on being infected and potentially transmitting it to their family. These perceptions translated to specific practices that include use of level 3 personal protective equipment, patient screening, triaging, and use of physical barriers to minimize environmental and contamination. While most are consistent with guidelines, some practices are neither based on sound scientific evidence nor correctly adhered to, including noncompliance with appropriate ultrasound transducer cleaning and disinfection. Regarding telesonography, only half of the respondents had good knowledge, with most having informal sources of information on the technology. Although the respondents have a good attitude toward it, only a few (15.8%) admitted to using it, mainly to confer with an expert or colleague (38.3%), and for teaching purposes (11.7%). @*Conclusions@#Obstetric–gynecologic sonologists in the Philippines are aware of the risks and have the same attitudes and perspective on COVID-19 infection as other health-care providers. Specific practices have been modified; however, the use of telesonography is not among the changes adopted.
