醫護第一 病人次之 • 6 sigma mistake control • 95.0-97.0 % 3-5 % N.I.C • 99.0-99.9 % 0.1-1.0 % ( 負壓, PPE) • 99.9997 % 0.0003 % NEW !! • 100 % 0 !! ?????
PCR test • Specificity 97% 3% pseudo-negative • 0.0003% • Universal precaution
1 Mistake ? 1 down, 10 isolate Exhausted for the rest 2 mistakes - - - - - -
Shut down & Quarantine of the hospital Next step Only to approach 100 % SARS as a ghost shadow , 可敬的對手 mistake is acceptable
Casual mistake is acceptable • When this is all over • And if we are still alive • Than we can take off our mask • And to get to know each other better Muh-Yong Yen 桃榮, 仁濟

Epidemiology of a common cold • lessons from flu. • lessons from AIDS & Polio
Epidemiology of a common cold • lessons from nosocomial infection • lessons from HK outbreak
Super virus ? ! • 香港 -- 曹婦 -- 和平 • 廣東 -- 台商 -- 台灣 • 劉姓醫師 in Honk Kong • 勤姓台商 in Taiwan • Both probably not the 1st case of the region
和平 vs 非和平 Triage and Dispatch • 和平 ( outbreak ) • Virulence, infectivity • Treat the case cautiously • PPE • 非和平 (endemic nosocomial infection) • Treated it as previous rules • Case identification ?
Case identification for super virus ? • the 1 st index case could always be sacrificed • Be prepared for the case surveillance (through 1st index case ) and fighting for incoming outbreak.
When & where for next super virus ? Find it and control it, Yet prepared for the casualties of war
surveillance • Definition: keep rolling for all aspect • In the front, there is no SOP • Case definition for the community outbreak: • Clustering of the acute respiratory symptoms • Home medication and observation for the fever / cough cases. • 單一窗口 • in community/hospital/ city/county/nation • Site of surveillance • ER, GP/OPD, entrance of buildings

Case Definition / case finding • SARS vs non- SARS • 和平 case mix & cohort • ER case mix & cohort • Probable case / suspect case / etc • need to real-time change case definition urgently as battle has evolving form hospital into community ( super virus )
