How should clinical surfaces not protected by impervious barriers be disinfected?

The correct approach to disinfecting clinical surfaces that are not protected by impervious barriers involves a two-step process: cleaning followed by disinfection using a hospital-grade low to intermediate level germicide. The cleaning step removes visible debris and organic matter, which is essential because disinfectants work more effectively on clean surfaces. Simply applying a disinfectant on a dirty surface can hinder its effectiveness, as organic matter can shield pathogens from the active ingredients in the germicide.

Using hospital-grade disinfectants is crucial as they are formulated to kill a wide range of microorganisms, making them suitable for clinical environments where maintaining a high level of hygiene is paramount. The low to intermediate levels of germicides are specifically designed to address the needs of many healthcare settings and ensure effective disinfection without being overly corrosive or harsh on surfaces.

Other methods, such as using a dry cloth, do not provide the necessary cleaning or disinfection, and employing only high-level disinfectant sprays may not adhere to the required protocol of cleaning prior to disinfection. Equally, merely cleaning with water is insufficient to ensure that all pathogens are effectively eliminated. Therefore, the recommended process of cleaning followed by the use of a suitable hospital-grade disinfectant is essential for maintaining safety and compliance in a clinical setting.
