What term defines the factors that include inadequate cleaning and improper storage?

The term that best defines factors such as inadequate cleaning and improper storage is "Contamination Factors." This term encompasses circumstances and practices that lead to the presence of harmful microorganisms or pathogens on surfaces and instruments due to subpar hygiene protocols. Inadequate cleaning fails to remove dirt, organic matter, and microorganisms, while improper storage can allow for the growth of bacteria and other pathogens due to unsuitable conditions, such as humidity or temperature changes.

On the other hand, biofilms refer specifically to collections of microorganisms that attach to surfaces and form protective layers, which can be a consequence of poor cleaning but do not encompass the broader idea of cleaning and storage practices. Sterilization is a process that completely eliminates all forms of microorganisms, ensuring that instruments and surfaces are free of any pathogens but does not address the practices that lead to contamination. Disinfection refers to processes that reduce the number of pathogens to safe levels but again does not relate directly to issues like inadequate cleaning and improper storage. Thus, "Contamination Factors" is the most suitable term to describe these conditions.
