Abstract

OBJECTIVE:

To assess the ability of non-certified clinicians to interpret guaiac test results.

METHODS:

50 clinicians were shown photographs of 20 guaiac test cards. They were asked to classify these as positive, negative, or uncertain.

RESULTS:

31 nurses, 4 clinical assistants, 7 emergency attending MDs, 2 resident MDs, and 6 medical students comprised the study group. Mean correct percentages for 15 clearly positive or negative guaiac test cards ranged from 87% to 96% in each of the above groups. Correct results were lower for five of the borderline positive guaiac cards.

CONCLUSION:

This study demonstrates that all clinician groups correctly interpreted the guaiac result most of the time, but there was a moderate error rate. This data supports the Joint Commission standard for this particular point of care test; clinicians interpreting guaiac testing should be trained with demonstrated competency.
