Reusable medical device pre-cleaning in care units: what are the indicators to prevent biofilm formation and control occupational biological risk?

The pre-cleaning of reusable medical devices is essential for successful cleaning, as it prevents biofilm formation that can compromise disinfection and sterilization. This study aimed to reflect on the recommendations regarding the pre-cleaning of reusable medical devices carried out in care units, such as wards, based on recommendations from guidelines/standards related to this important step in reusable medical device reprocessing. However, recommendations for pre-cleaning in care units are not unanimous and contrast with detailed recommendations on reusable medical device reprocessing in the Central Sterile Services Department (CSSD). This topic is an unresolved issue, strongly related to patient and worker safety, which points to the lack of investigations to provide indicators of best practice and highlights the need for shared responsibility management between care units and CSSD.
