“…The previously published study describes the details of ultrasound performance, quality control of sonographers, generation of the study cohort and data extraction. 10 This is briefly summarised here. The same group of 13 sonographers performed ultrasounds throughout the state, and there is continuous quality control with additional training and supervision as needed.…”

“…1,5 While interpretation of many non-obstetric radiological studies is done remotely, pre-natal ultrasound has traditionally been performed and interpreted in the same location. 10 To our knowledge, there are no large studies validating the accuracy of teleultrasound compared with onsite ultrasound in detecting congenital anomalies. Many interpreting physicians prefer to perform at least part of the study themselves, and the ability to view remote, real-time ultrasound has been limited by technology.…”

Introduction/Purpose: There are no large validation trials comparing teleultrasound to on-site ultrasound. We aim to compare the sensitivity and accuracy of teleultrasound and demonstrate that teleultrasound is not inferior to on-site ultrasound in the pre-natal diagnosis of fetal anomalies. Methods: All targeted ultrasounds performed between November 2010 and December 2012 were considered. We excluded studies performed at less than 17 weeks' gestation, on multiple gestations and for reasons other than an anatomical survey. Postnatal diagnoses were obtained from a state level mandatory birth defects surveillance programme. Descriptive statistics (sensitivity, specificity, positive and negative predictive values and accuracy) were calculated for both groups. A test of noninferiority was performed, with the non-inferiority difference set at 0.15. Results: The teleultrasound and on-site ultrasound groups consisted of 2368 and 3145 studies, respectively. The sensitivity of teleultrasound and on-site ultrasound was 57.46% and 76.57%, and the accuracy was 95.9% and 90.97%, respectively. The observed sensitivity difference was À0.1911. The accuracy, specificity, positive and negative predictive values of teleultrasound are similar to on-site ultrasound. Discussion: Teleultrasound is inferior to on-site ultrasound in the detection of fetal anomalies; however, it has improved accuracy, as well as higher negative and positive predictive values. A negative teleultrasound is more likely to identify a non-anomalous fetus, and a positive teleultrasound is more likely to correctly identify an anomalous fetus. Conclusion: Teleultrasound has an important role in pre-natal diagnosis for those patients unable or unwilling to travel for an onsite ultrasound.

Identifying enablers and barriers to teleultrasound use for remote settings: A scoping review

Introduction/PurposeTeleultrasound connects expert point‐of‐care ultrasound (POCUS) users with remote community and rural sites. Evolving technologies including handheld devices, upgraded image quality, and the ability to transmit over low bandwidth connections increase POCUS education, accessibility, and clinical integration. Potential teleultrasound venues include low‐resource settings, prehospital care, and austere environments (high altitudes, microgravity, conflict zones, etc.). This scoping review assesses current teleultrasound uses and identifies implementation enablers and barriers.MethodsUsing the PRISMA‐ScR checklist, PubMed, Embase, and Cochrane were searched on 16 August 2024 for teleultrasound studies. Two reviewers independently screened results and abstracted data using a data collection table. 165 articles met the following inclusion criteria: research studies describing teleultrasound, involving humans, including healthcare workers, with remote point‐of‐care or medical ultrasound use, in any setting, and in English.ResultsTeleultrasound studies were reported in most specialties and across all continents. Most were prospective (100 studies), review articles (27), or case studies (14). Study quality was variable, with 28 high quality, 77 moderate, 54 low, and 6 very low (GRADE assessment tool). Common themes that emerged include (1) type of image transmission method utilised, (2) remote provider training and curriculum development, (3) feedback methods between expert and novice users, (4) technologies and devices used, and (5) enablers and barriers to guide future teleultrasound implementation and training strategies.ConclusionOverall, the teleultrasound literature is heterogeneous in setting, design, and quality outcomes. As teleultrasound technology evolves and the use expands, future studies should standardise protocols and ensure image quality fidelity to optimise remote patient care.
