目的 了解广东省有急性传染性非典型肺炎 (SARS)接触史的医务人员在防治SARS时期的个人防护状况 ,评价防护措施对预防SARS感染的效果。方法 对广东省 9所诊治SARS的医院中所有有SARS接触史的工作人员进行调查。结果 16 4 5名调查对象中有 15 2例感染SARS ,其中有 79 6 1%的确诊时间在 2 0 0 3年 2月 ,随时间推移而确诊病例数迅速减少 ;同时 ,所有调查对象在第 1次接触SARS时对各项防护工具的使用率随时间推移而增加 ,趋势检验均有统计学意义 ;第 1次接触SARS时使用各项防护工具的医务人员感染SARS的频率均低于没有使用者 ;9所医院医务人员对防护工具使用率和感染率也呈负相关关系 ,相关系数为 - 0 7386 ,P值为0 0 2 3。结论 对与SARS患者接触的医务人员 ,采取积极有效的防护措施能大大降低感染的风险 ,从而保护其身体健康。
Objective To understand the personal protection status of medical staff in the history of SARS exposure in Guangdong Province and to evaluate the effect of protective measures on preventing SARS infection. Methods A total of 9 SARS-exposed hospitals in Guangdong Province were surveyed. Results 15 2 out of 164 subjects were infected with SARS, of which 79 61% were diagnosed in February 2003. The number of confirmed cases decreased rapidly with the passage of time. At the same time, The rate of use of various protective tools increased with the passage of time in one contact with SARS and the trend test was statistically significant. The frequency of SARS infection among medical staff using various protective tools during the first exposure to SARS was lower than that of unused There was also a negative correlation between the utilization rates of protective tools and infection rates in nine hospital medical staffs, with a correlation coefficient of -0.7386 and a P value of 0 0 2 3. Conclusion The positive and effective protective measures for medical staff who come into contact with SARS patients can greatly reduce the risk of infection and thus protect their health.
