Time and speed are vital aspects of clinical diagnosis decision-making. This
study aimed to investigate the gaze patterns, diagnosis speed and accuracy
with and without the assistance of clinical history while interpreting clinical
findings. This cross-sectional study employed convenience sampling to
recruit 28 normally sighted final year students with ongoing clinical training.
Each student was shown six clinical findings, half of which accompanied a
brief clinical history in prose, and the other half were not. First, the clinical
history was presented to be read by the participants, followed by providing
clinical findings regarding fundus picture images. The participants were
asked to make a diagnosis based on a clinical finding presented to them. The
Dikablis eye tracker was used to record and track the gaze patterns during
the treatment. The assessment had no time restriction, and the gaze patterns
(number of fixations, fixation duration, number of saccadic, and saccadic
angles) were retrieved from the D-Lab software. Diagnostic speed was
calculated based on the time taken for the students to provide a clinical
diagnosis. Diagnosis accuracy was the score of correct or incorrect of the
given diagnosis. Comparison of gaze patterns in interpreting clinical
findings with clinical history and without clinical history showed no
statistically significant difference for all gaze patterns including the number
of fixation (p=0.20), fixation durations (p=0.98), number of saccadic
(p=0.33) and saccadic angle (p=0.77). There was also no statistically
significant difference in both diagnosis accuracy (p=0.14) and diagnosis
speed (p= 0.20) between both conditions. However, there was a strong
correlation between the number of fixations and diagnosis speed with (r =
0.708, p < 0.05) and without (r = 0.618, p < 0.05) clinical history. A
moderate correlation was found between the number of saccades and
diagnosis speed with (r = 0.578, p < 0.05) and without (r = 0.424, p < 0.05)
clinical history. In conclusion, a brief clinical history does not appear to
influence the gaze patterns, diagnosis speed and accuracy in evaluating the
clinical findings. However, the gaze patterns highly correlated with the
diagnosis speed in clinical decision-making. These findings indicate
cognitive processing during clinical decision-making, which might benefit
clinical educators in enhancing the clinical teaching approach and quality.
