【摘要】 目的 :分析SARS疫区综合性医院中包括放射科应急隔离信息管理系统在内的各种应急隔离措施的应用与院内医务人员感染趋势的关系。方法 :按时间段分组研究 ,宣布为疫区前的时间段为A组 ,采取普通防护措施 ;建立隔离区前的时间段为B组 (可疑或者肯定诊断的患者仍然在放射科拍摄胸片 ) ;建立完善的应急隔离系统 ,包括放射科影像传输与报告系统的时间段为C组。记录每日各组医务人员感染 (确诊 )人数、院接触人数。结果 :A组感染率呈明显上升趋势 ,回归系数为 0 .0 0 0 5 4 5 ,P =0 .0 4。B组上升趋势较A组稍微下降 ,回归系数为0 .0 0 0 16 4 ,P =0 .14。C组上升趋势明显下降 ,回归系数为 0 .0 0 0 0 37,P =0 .0 2。结论 :在不同防护措施情况下 ,医务人员感染率具有不同的发展趋势。当采取普通的防护措施后 ,院内医务人员的感染率上升的趋势与A组相比明显下降 ;而当进一步实行SARS隔离区措施后 ,院内医务人员的感染率上升趋势与A组相比进一步下降更多还原

【Abstract】 Objective: To analyze the relationship between the rate of the in hospital medical staff SARS infection and the measure of isolation which including the application of the emergency isolation radiology information system (EIRIS) in polyclinic. Methods: The groups were classified according to the application of the prevention and protection measure. Group A referred to the stage before the declaration of infectious area was made. Group B was defined as the stage in which the application of common measures of the prevention and protection were made, but the isolation measure was not taken(the suspected or diagnosed cases had the chest X ray film examination in the department of radiology). Group C was the stage after the startup of the isolation measure including the application of EIRIS. the number of the diagnosed cases, the medical staffs exposed, and the diagnosed cases of medical staffs were recorded. Results: In group A, the infectious rate of in hospital medical staffs showed a marked ascending trend with the regression coefficient of 0.000545, P =0.04. The rate showed a litte descending trend in Group B compared with that in Group A with the regression coefficient of 0.000164, P =0.140. while marked descending trend compared with group A was demonstrated in group C with the regression coefficient of 0.000037, P =0.02. Conclusion: The trend of the in hospital medical staffs infection rate changed with different style of prevention and protection measures. With the application of the common measure of the prevention and protection,the rate was significantly lower than that in group A. After the application of the isolation measures including EIRIS, the rate showed the descending trend much further.更多还原
