Objective: “Rapid screening, targeted sampling, objective test” is an efficient test
model. The factors affecting the efficiency include false screening rate, missing rate
and rapid screening time. However, only missing rate and accuracy have been used
as technical requirements to evaluate rapid screening method. In this study, efficiency
was regarded as evaluation index of quick testing method. Method: The evaluation
model of quick testing efficiency was established by comparing time of routine
testing and quick testing. By simulation calculation, the effect factors such as rapid
screening time, false screening rate, missing rate and defective rate were analyzed. Results: The calculation formula of efficiency was derived. Simulation results
showed that the lower defective rate, the higher efficiency; the smaller missing rate,
false screening rate, or screening time, the higher efficiency and the degree of improving
efficiency is related to defective rate; sometimes, the screening time is the
most important factor affecting the efficiency. In certain cases, if the false screening
rate or missing rate is 50%, the efficiency can be increased by more than 10 times. Conclusions: Taken together, this study highlighted a role of efficiency which functioned
as an index to evaluate rapid screening. Quick testing efficiency evaluation
model can be used for the calculation efficiency, and can be used to analysis the relationship
between efficiency and the influence factors, and can provide the theoretical
foundation for rapid screening method development and evaluation.
