Workload Volume and Educational Activities:
Radiologists’ workload volume especially in on-call hours vary mostly depending on the ER admission rates. At our institution, primarily one radiologist at night shifts and one radiologist at working hours were responsible for emergency cases. The total number of chest-CT scans reported have markedly increased up to 140 cases/day.
Educational activities dedicated to the novel-coronavirus infection that took place within the radiology department and also within institutional panels, symposiums organized by national radiological society, ministry of health and online meetings have been investigated with their dates (appendix 1). It has been found that local/national educational activities mostly aggregated at the end of March and the first half of April.
Results of re-evaluation of chest CT scans were correlated with former documents and gold standard PCR test results. IEs were correlated with workload and educational activities. By this way, the learning curve in radiological diagnosis of COVID-19 pneumonia was tried to be established. It has been found that, the number of chest-CT scans increase to the top level at the beginning of April than gradually decrease. On the other hand, the distribution of the ratio of IEs to the number of chest-CT scans among this three month period have pointed out that the ratio of IEs gradually decrease more than half after April, from 20.2% to 11.18% (figure 1).
