摘要
目的评价流行病学相关因素对香港特区医护人员SARS流行的影响。方法采用构筑式多元逐步回归和Logistic逐步回归法评估气象、时间、各类SARS病例、干预措施和医院感染等因素对香港医护人员SARS流行的影响。结果在消除其他因素的可能影响后,日平均气温每上升1℃,香港医护人员SARS每日病例可能下降约0.7例。在港府加强前线医护人员的防护装备后,医护人员SARS每日病例可能减少5.4例。随着时间的推延,医护人员SARS每日病例可能减少约0.1例。ICU的SARS病人每增加100例,医护人员SARS每日病例可能增加约3例。日平均气温低于24.6℃时,医护人员SARS爆发的危险性是平均气温高于24.6℃时的18.18倍。港府加强前线医护人员防护装备之前,医护人员爆发SARS的估计危险性是防护装备加强后的15.87倍。结论日平均气温、加强防护装备、流行时间及ICU的SARS病人可能对医护人员SARS的流行构成影响。
Objective To evaluate the impact of relative epidemiologic factors on hospital staff in Hong Kong Special Administrative. Methods A structural multiphase regression analysis and a Logistic regression analysis were applied on three hierarchical clusters of variables involved in the SARS epidemic in hospital staff in Hong Kong. These factors included meteorological condition, epidemic day, all kinds of SARS cases, intervention measures, hospital infection and so on. Results Adjusted the factors mentioned above, the daily new cases in the hospital staff in this region was decreased by an average of 0.7 patients when the air temperature increases by 1℃. The reinforce of defense equipment to the front line healthcare staff reduced by an average of 5.4 cases occurred in hospital staff daily. The daily new cases in healthcare staff was decreased by an average of 0. 1 with epidemic time lapsed, and increased by 3 when SARS patients in ICU increased 100. The estimated risk of a larger SARS epidemic in this region was 18. 18-fold and 15.87-fold higher when the air temperature was lower than 24.6℃, and before strengthening the defense equipment to the front line healthcare staff, respectively. Conclusion The air temperature,the reinforce of defense equipment,the epidemic time and the SARS patients in ICU are potential factors on SARS epidemic in hospital staff in Hong Kong.
