Summary of research attempting to quantify the scope and success of teleradiology services in Africa.
| STUDY | PUB YEAR | COUNTRY | STUDY DESIGN | RESULTS | BARRIERS IDENTIFIED |
|---|---|---|---|---|---|
| Coulborn et al. [17] | 2012 | Malawi | Descriptive analysis | One hundred fifty-nine images (from 158 patients) were reviewed by teleradiology. Teleradiology changed patient management in 36 cases (23.5%). | Image quality on teleradiology systems |
| Zennaro et al. [16] | 2013 | Angola | Feasibility study | Twenty thousand five hundred sixty-four digital X-ray images were created with no major technical problems and no need for on-site supervision. “Novel” digital radiology system retained and improved image quality. | Cost of equipment |
| Halton et al. [15] | 2014 | Multiple | Retrospective analysis | Mean teleradiologist response time is 6.1 hours. Seven out of eight respondents indicated teleradiologist consults found to be favorable; six out of six respondents indicated teleradiologist input to assist in the clarification of diagnosis. | Low and variable volume in the usage of teleradiology service |
| Sangare et al. [18] | 2015 | Mali | Retrospective analysis | Teleradiologists provided the sole diagnosis for 29% of cases. No diagnosis by regional physician decreased from 93% to 24%. | Infrastructure (internet connection); the low volume of cases; cost of services for patient and provider |
| Crumley et al. [19] | 2020 | Democratic Republic of Congo | Paired before-after study | Diagnosis changed following teleradiology in 62% of cases, and treatment plans changed in 61%. | Cost and maintenance equipment |
| Essop and Kekana [20] | 2021 | South Africa | Qualitative analysis | Narrative feedback predominately negative from referring clinicians and technologists. | Communication between consulting physician, teleradiologist, and technologist |
