Results
For every shift,
the proportion of conformities and non-conformities (p chart), the total number of non-conformity exams (np chart) and the total number of non-conformities in each sample (c chart) were determined.
For each chart,
superior and inferior control limit,
standard deviation and limit warnings were calculated.
From the 860 examinations,
83% (712) of observed radiograms were classified as non-conform.
The highest difference between the proportion of conformity with non-compliant was identified on the night shift and at morning shift where this ratio is below.
Analyzing the data by work shift,
37,7 % examinations were non-conform in morning shift,
26% in afternoon shift and 19,1% in night shift (Fig. 2).
The patient positioning is the most common cause of non-conformities in radiograms (87%),
followed by incorrect image post-processing (7%) and presence of artifacts (6%) (Fig. 3).
The proportion of conformities and non-conformities (p charts) by work shift are visible on the Fig. 4 ,
Fig. 5 and Fig. 6 The total number of non-conformity exams (np chart) by work shift are visible on the Fig. 7,
Fig. 8 and Fig. 9.
And finally,
the total number of non-conformities in each sample (c chart) by work shift are visible on the Fig. 10,
Fig. 11 and Fig. 12.
