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).
