27. Results
Looking for just distress
detection sensitivity of 11.2% (95% CI 6.9% to 16.9%)
detection specificity of 98.3% (95% CI 95.2 to 99.7%).
Looking for any mental health complication their
sensitivity was 50.6%
specificity 79.4%
There was significantly better performance using the broad approach
rather than a narrow focus 65.4% vs 56% (Chi² = 4.3,p = 0.037).
28. Predictors
Examining predictors, clinicians had better ability to
recognize higher severities of distress (adjusted R2=
0.87 p = 0.001). There was a trend for better
recognition by community than chemotherapy nurses.
There was no difference according to the stage or type
of cancer.

30. Summary
Detection of depression is low in all groups
Detection of depression has some untested assumptions
Most clinicians are not using tools
Detection of distress is almost imperfect
=> Whose opinion is most important
