The incidence of epistaxis admissions to hospital and their relationship to ambient temperature is examined. A retrospective analysis of 1211 patients with epistaxis sufficiently severe to warrant hospital admission was performed over a period of 1836 consecutive days. Daily average temperature data for this time-period were examined and compared with admission rates. A marked increase in hospital attendance was apparent during colder days. Patients were admitted at a rate of 0.829 patients per day for temperatures less than 5 degrees C, (95% Confidence Interval: 0.737-0.928), compared with 0.645 patients per day for temperatures between 5.1 and 10 degrees C, (95% 0.586-0.708). On average the population of epistaxis patients attended on days that were 0.6 degree C colder (95% Confidence Interval: 0.2 degree C-0.9 degree C) than the average temperature for the time examined (P < 0.005, student's t-test).
研究了鼻出血住院的发生率及其与环境温度的关系。对1211例因鼻出血严重到需要住院治疗的患者进行了为期1836天的回顾性分析。检查了该时间段的每日平均温度数据，并与入院率进行了比较。在较冷的日子里，医院就诊人数明显增加。温度低于5摄氏度时，患者的入院率为每天0.829例（95%置信区间：0.737 - 0.928），而温度在5.1至10摄氏度之间时，入院率为每天0.645例（95%置信区间：0.586 - 0.708）。鼻出血患者就诊当天的平均温度比所研究时间段的平均温度低0.6摄氏度（95%置信区间：0.2摄氏度 - 0.9摄氏度）（P < 0.005，学生t检验）。
