[Thoughts upon the construction of requirements of disinfection procedures concerning contaminated hands - an analysis (author's transl)]

Abstract

The construction of detailed test methods for the evaluation of disinfection procedures has primarily to be based upon requirements which have to be formulated in advance. A recently proposed test model is being discussed on the basis of 5 conceivable formulations of possible requirements. Essentially, they may be allotted to two types: the one implies the comparison of the disinfection procedure to be tested as against an hypothetical procedure. The other makes use of the simple comparison with a concrete standard procedure and is preferable to the first possibility for several reasons. The presented, mathematical formulations of the structure describing the proposed model represents a first approximation in order to permit the comparison of disinfection effects on the hands under assistance of probabilistic methods and eliminating other effects inherent ot a test method.
