Which statement is not true concerning the surgical scrub process?

The assertion that increasing the duration of the scrub is the most effective method of reducing the burden of microorganisms is not accurate. While duration can contribute to the effectiveness of a surgical scrub, it's not the most critical factor. Most of the research emphasizes that the technique and the agent used are more important than simply extending the time spent scrubbing. Proper technique includes thorough coverage of all surfaces, including the fingers, hands, and forearms, as well as using appropriate antiseptic agents. The efficacy of hand antisepsis is also closely related to the scrubbing process itself, with specific guidelines in place to ensure the procedure is done correctly within a reasonable time frame.

The emphasis on hand antisepsis before patient contact is indeed a critical practice in minimizing infection risk, as is ensuring that all parts of the hands and arms are scrubbed adequately. Scrubbing should be done with vigor but within a designated time rather than excessively extending the scrub time without attention to technique and method.
