Quantitative assessment of olfactory function in an industrial setting.
The University of Pennsylvania Smell Identification Test (UPSIT) was administered, on a volunteer basis, to workers frequenting the cafeteria of the corporate offices of a major chemical manufacturing company to (1) establish the level of acceptance of self-administered olfactory testing within such a setting, (2) determine the percentage of the sample that reported or evidenced marked olfactory impairment, and (3) develop guidelines for the use of the UPSIT as a corporate medical surveillance tool. The initial acceptance of the testing program was high. Thus, 640 of the cafeteria visitors agreed to take the test (total work force in building less than 1,000). However, only 52% of the tests handed out were completed by the employees and returned to the test examiners, possibly reflecting the informal atmosphere in which they were distributed. Of the group returning the tests, seven employees reported having smell problems due to allergies or sinus disease. However, all of these employees had normal UPSIT scores. Three subjects (1% of the sample) evidenced marked olfactory dysfunction. Of these three, only one was aware of the problem before testing. On average, the corporate subjects significantly outperformed matched control subjects obtained from previous administrations of the UPSIT at health fairs and other public events, although the difference was less than half a point (37.89 v 37.53; P less than .004). As in previous studies, the test scores of women were slightly, but significantly, higher than those of men (respective means = 37.98 v 37.80, P less than .04).
