    Area of Science:

    • Microbiology
    • Biostatistics
    • Public Health

    Background:

    • Handwashing is crucial for infection control.
    • Evaluating handwashing efficacy requires quantitative microbial analysis.
    • Standardized protocols are needed for reliable comparisons.

    Purpose of the Study:

    • To present statistical procedures for comparing two handwashing protocols.
    • To estimate the relative efficacy of a test protocol versus a standard protocol.
    • To quantify microbial flora reduction through colony counts.

    Main Methods:

    • Experimental design comparing two handwashing protocols.
    • Collection and microbial colony count analysis of wash effluent.
    • Formulation and estimation of an odds ratio for efficacy comparison.

    Main Results:

    • Statistical procedures for analyzing effluent colony counts.
    • An odds ratio quantifying the relative efficacy of the test protocol.
    • Data reflecting the number of flora removed by each protocol.

    Conclusions:

    • The described statistical methods enable quantitative comparison of handwashing protocols.
    • The odds ratio provides a measure of relative microbial reduction.
    • This approach aids in selecting superior handwashing interventions.
