Methods and materials
A retrospective study was conducted in a public imaging department using a total of 860 random chest radiograms,
divided in 43 samples with 20 exams each.
The radiograms were analyzed according to a checklist based in the American College of Radiology guidelines to identify non-conformities in chest radiograms.
The conformities and non-conformities found were recorded and used to establish three types of quality control charts in order to suggest corrective actions for improvement:
- (1) the proportion of conformities and non-conformities (p chart),
- (2) the total number of non-conformity exams (np chart) and,
- (3) the total number of non-conformities in each sample (c chart).
Work shift was considered in this research and it were obtained 400 radiograms from morning shift,
280 from afternoon and 180 radiograms from night shift.
So,
the 860 examinations were gruped in 43 smaller samples vith 20 examinations each divided by morning (20),
afternoon (14) and night (9) shift (Fig. 1).
