Abstract
OBJECTIVE: To create a screening olfactory test based on the CCCRC (Connecticut Chemosen-sory Clinical Research Center). MATERIAL AND METHODS: We compare the screening test based on CCCRC with PST (Pocket Smell Test) based on UPSIT in 40 patients with nasal poliposis, in order to de-termine the specificity, sensitivity, positive predictive and negative predictive value. The validity index was 95% and accuracy rate was 10%. We determine unit cost, the time required to perform the test in outpatients office and how difficult it is to do the test. RESULTS: Sensibility was 88%, specificity was 77%. The positive predictive value was 34% and the negative predictive value was 94%. The unitary cost of our screening test was 0.57 euros when it is performed by a nurse. The unitary cost of PST is 1.76 euros. To perform our screening test took 2.8 +/- 0.4 minutes. The 96% of the patients thought the test was easy to do. CONCLUSION: Our test is a valid screening test to be used in patients with nasal poliposis.
