Question 10
A medical-document triage team lowers a classification threshold to catch more urgent cases. What fairness and reliability tradeoff should be checked?
Explanation
Correct Answer
A lower decision threshold generally flags more urgent cases but can also flag more nonurgent cases. Measuring recall and false-positive rates for each affected patient group shows both the safety benefit and any uneven escalation burden.
Incorrect Answers
Deleting the previous threshold’s test results removes the baseline needed to determine whether the new configuration improves urgent-case recall and at what cost. Traceable before/after results are essential when clinical escalation rules change.
Overall precision measures the share of positive predictions that are correct, but it cannot establish recall of urgent cases or whether false-alarm burdens differ by patient group. Threshold changes must be checked using subgroup recall and false-positive results.
An increase in escalated case volume does not tell the team how many are correct. Without confirmed diagnoses or review outcomes, it cannot quantify false alarms or whether one group receives disproportionate unnecessary escalation.
