Médecins Sans Frontières (MSF) began a pilot trial of store-and-forward telemedicine in 2010, initially operating separate networks in English, French, and Spanish; these were merged into a single, multilingual platform in 2013. We reviewed the pattern of teleradiology usage on the MSF telemedicine platform in the 4-year period from April 2010. In total, 564 teleradiology cases were submitted from 22 different countries. A total of 1114 files were uploaded with the 564 cases, the majority being of type JPEG (n = 1081, 97%). The median file size was 938 kb (interquartile range, IQR 163–1659). A panel of 14 radiologists was available to report cases, but most (90%) were reported by only 4 radiologists. The median radiologist response time was 6.1 h (IQR 3.0–20). A user satisfaction survey was sent to 29 users in the last 6 months of the study. There was a 28% response rate. Most respondents found the radiologist’s advice helpful and all of them stated that the advice assisted in clarification of a diagnosis. Although some MSF sites made substantial use of the system for teleradiology, there is considerable potential for expansion. More promotion of telemedicine may be needed at different levels of the organization to increase engagement of staff.
Médecins Sans Frontières (MSF) is a humanitarian organisation which provides emergency medical aid in challenging settings; field staff often diagnose and treat patients using limited resources and without the expertise of specialists. Teleradiology is available for MSF sites which use digital computed radiography (CR) imaging or conventional film and chemistry. We conducted a retrospective study of the quality of X-rays utilised by MSF for teleradiology diagnosis over a one-year period. All plain X-ray examinations referred for interpretation using two MSF teleradiology platforms in 2012 were assessed against 15 image criteria and further evaluated as being either diagnostic or non-diagnostic. The sites studied sent an average of 115 images (range 10-452). Images were a mixture of chest, skeletal and abdominal radiographs. The majority of the images were CR (n = 597, 74%). Three sites were MSF/Epicentre installed and operated (Epicentre is a research facility affiliated with MSF); five sites were operated by the ministry of health, imaging patients referred by MSF. The sites performing poorest for quality were all facilities which used film and chemistry (53% non-diagnostic images). The sites performing better for quality were facilities which used CR digital imaging (12% non-diagnostic images), two of which had also undergone radiographer training. Our study suggests that transitioning to CR digital imaging has the potential to improve image quality compared to film and chemistry. Radiography training should be made a priority for all sites with X-ray services. The continued utilisation of X-ray services by MSF where images have proven to be consistently poor should be re-considered.
This study demonstrated limited impact of the introduction of a CRRS on CXR accuracy and agreement amongst non-expert readers. The role in which CXRs are used for TB diagnosis in a HIV-positive cohort in similar clinical contexts should be reviewed.
