Abstract
BACKGROUND: Shifting X-ray interpretation to non-radiologists can help to address radiologist shortages in developing countries. OBJECTIVE: To determine the change in accuracy of non-radiologists and radiologists for the radiographic diagnosis of paediatric tuberculosis after a short skill-development course. MATERIALS AND METHODS: Participants interpreted 15 paediatric chest radiographs before and after a 30-minute course using three possible responses: (1) diagnostic for tuberculosis, (2) abnormal but inconclusive for diagnosis of tuberculosis and (3) normal. We compared proportions of correct diagnoses, sensitivity, and specificity, before and after the course. RESULTS: We included 256 participants comprising 229 non-radiologists (134 radiographers, 32 paediatricians, 39 Médecins Sans Frontières clinicians and 24 physicians including paediatricians) and 27 radiologists. Mean change proportions of correct diagnosis ranged from -27% to 53% for individuals and 9% to 20% for groups. All groups showed a statistically significant improvement. Mean change in diagnostic sensitivity ranged from -38% to 100% for individuals and from 16% to 41% for groups. All groups showed a statistically significant improvement. Mean change in specificity ranged from -57% to 57% for individuals and from -15% to -4% for groups. The decrease was statistically significant for physicians, paediatricians and radiographers. CONCLUSION: The course resulted in increased correct diagnoses and improved sensitivity at the expense of specificity.
