5 CONCLUSION
Epidemiological investigation, personnel management, disinfection
isolation, training and education and surveillance form a quality
management circle of ward managetment based on
closed-loop management.11Robert
S. Kaplan, David P. Norton. Closed-loop management: from strategy to
operations [J]. Harvard business review, 2008;(2): 46-60. By
optimizing the personnel management and supplies management, as well as
infection control guidelines, we have controlled the source of
infection, cut off the transmission route and ensured the normal
operation of the ward without any covid-19 case. Only with positive
response, can COVID-19 prevention
and medical work be in an orderly manner.
