Abstract

OBJECTIVE

To create a short olfactory test, Connecticut Smell Test (CST), based on the CCCRC (Connecticut Chemosensor and Clinical Research Center).

DESIGN

A prospective patient-based study.

SETTINGS

Smell and Taste Outpatient Clinic at the Fundación Hospital Alcorcón, Madrid, Spain.

MATERIAL AND METHODS

We compared a short test based on the CCCRC with the Pocket Smell Test (PST) based on the University of Pennsylvania Smell Identification Test) UPSIT in 40 patients with nasal polyposis, in order to determine the specificity, sensitivity, positive predictive and negative predictive values. The validity index was 95% with an accuracy rate of 10%. We determined unit cost, the time required to perform the test in the outpatient office and the difficulty to perform the test.

RESULTS

The sensibility was 93.3% and the specificity was 76% with a positive predictive value of 70% and a negative predictive value of 95%. The unitary cost of CST was euro0.65 when it is performed by a doctor. The unitary cost of PST is euro1.76. Our short test took 34 seconds to perform. More than 96% of the patients thought the test was easy to do.

CONCLUSION

Our test is a valid, easy and quick test to be used in patients with nasal polyposis.

摘要

目的

基于康涅狄格化学感觉和临床研究中心（Connecticut Chemosensor and Clinical Research Center，CCCRC）创建一个简短的嗅觉测试，即康涅狄格嗅觉测试（Connecticut Smell Test，CST）。

设计

前瞻性基于患者的研究。

地点

西班牙马德里阿尔科孔基金会医院嗅觉和味觉门诊。

材料和方法

我们将基于 CCCRC 的简短测试与基于宾夕法尼亚大学嗅觉识别测试（University of Pennsylvania Smell Identification Test，UPSIT）的袖珍嗅觉测试（Pocket Smell Test，PST）在 40 例鼻息肉患者中进行比较，以确定其特异性、敏感性、阳性预测值和阴性预测值。有效性指数为 95%，准确率为 10%。我们确定了单位成本、在门诊进行测试所需的时间以及进行测试的难度。
