“…The TPF at midpoint of the TP range of the operating points was significantly less for residents than faculty (0.294 vs. 0.423, F (1, 18) = 5.30, P < 0.05). Similarly, the midpoint of the FP range of the operating points was significantly less in residents than faculty (0.058 vs. 0.093, F (1, 18) = 4.72, P < 0.05.…”

“…Similarly, the midpoint of the FP range of the operating points was significantly less in residents than faculty (0.058 vs. 0.093, F (1, 18) = 4.72, P < 0.05. Taken together, these findings suggest that residents were less willing to report abnormality than faculty, reducing both true and false positive responses.…”

“…Recently decision threshold shifts have been found in chest radiography SOS (17, 18) supplanting the reduction in detection accuracy found in the past (15, 16). Decision threshold shifts reflect reductions in TPFs accompanied by reductions in FPFs: the ROC points move downward along the ROC curve.…”

“…In chest radiography, classic SOS studies showed a reduction in accuracy (as measured by Receiver Operating Characteristic (ROC) analyses) for the detection of native lesions or abnormalities in the presence of simulated pulmonary nodules (15, 16). A recent studies (17, 18) reexamined the SOS effect in chest radiography with modern imaging techniques (i.e., computed radiography (CR) images viewed on a workstation monitor) instead of film images on a view box. In contrast to the previous film-based studies, they observed that diagnostic accuracy for native lesions was not affected by the addition of nodules.…”

“…Eight hours was the average amount of prior reading time in previous studies of reader fatigue that demonstrated oculomotor and subjective fatigue in readers. Specifically, we wanted to find out whether SOS under conditions of fatigue would lead to an SOS effect on detection accuracy as documented in the original SOS studies (15, 16) or an SOS effect on decision thresholds as found in the more recent ones (17, 18). …”

Purpose To assess the nature of the satisfaction of search (SOS) effect in chest radiography when observers are fatigued; determine if we could replicate recent findings that have documented the nature of the SOS effect to be due to a threshold shift rather than a change in diagnostic accuracy as in earlier film-based studies. Materials and Methods Nearing or at the end of a clinical workday, 20 radiologists read 64 chest images twice, once with and once without the addition of a simulated pulmonary nodule. Half of the images had different types of “test” abnormalities. Decision thresholds were analyzed using the center of the range of false positive (FP) and true positive (TP) fractions associated with each Receiver Operating Characteristic (ROC) point for reporting test abnormalities. Detection accuracy was assessed with ROC technique and inspection time was recorded. Results The SOS effect was confirmed to be a reduction in willingness to respond (threshold shift). The center of the FP range was significantly reduced (FP = 0.10 without added nodules, FP = 0.05 with added nodules, F(1,18) = 19.85, p = 0.0003). The center of the TP range was significantly reduced (TP = 0.39 without added nodules, TP = 0.33 with added nodules, F(1,18) = 10.81, p = 0.004). Conclusion This study suggests that fatigue does not change the nature of the SOS effect, but rather may be additive with the SOS effect. SOS reduces both true and false positive responses, whereas fatigue reduces true positives more than false positives.
