背景：設法從某次的健檢中獲得一般族群之鼻及鼻竇炎症狀檢測分數 (20-item sinonasal outcome test，SNOT-20) 與胃酸逆流症狀指數 (reflux symptom index，RSI)。材料及方法：針對本院在 2007 年 1 月時的員警高級體檢，由作者進行體檢之對象共計 208 名，請他們填寫一份含有 SNOT-20 與RSI 問項之問卷。最後求得 SNOT-20 與RSI 分數之平均值、標準差與中位數。結果：SNOT-20 之平均值為 19.3 ，標準差為 14.4 ，中位數為 17.5 ；而 RSI 之平均值為 5.4，而標準差為 6.6 ，中位數為 3。結論：這些受檢者中潛在著鼻及鼻竇炎或胃酸逆流之病患，因此，結果中的數值可以作為門診時評量這類病患時的對照。

Background: we obtained a common value of 20-Item Sno-Nasal Outcome Test (SNOT-20) and Reflux Symptom Index (RSI) from a certain health examination. Materials and methods: 208 examinees were enrolled at a police health examination in January 2007. They wrote a questionnaire with SNOT-20 and RSI, and then were examined by the author. Finally, the average and standard deviation of SNOT-20 and RSI were obtained. Results: the average of SNOT-20 is 19.3, and the standard deviation is 14.4, and the medial value is 17.5; besides, the average of RSI is 5.4, and the standard deviation is 6.6, and the medial value is 3. Conclusion: the 208 examinees might include patients with rhino-sinusitis or acid reflux. Therefore, the resultant values can be contrasted for patients of rhino-sinusitis or acid reflux at outpatient department.
