Beyond Environmental Services: Common Cleaning Gaps in Patient Care
During rounds in an outpatient clinic, I noticed staff cleaning vaginal ultrasound probes between patients with a quaternary ammonium disinfectant wipe (a low-level disinfectant appropriate for use on devices that come in contact with intact skin). When I asked about the process, the staff explained that because the probe was covered with a probe cover, they assumed a disinfectant wipe was sufficient. While probe covers provide an important layer of protection, they can leak or develop microscopic perforations. Because contamination can still occur, these probes should always be treated as if they have contacted mucous membranes and require a high-level disinfectant (appropriate for use on devices that come in contact with mucous membranes or non-intact skin) instead of a low-level disinfectant.
Gaps in knowledge and execution.
This type of misunderstanding is not uncommon in health care and illustrates a broader challenge: cleaning failures are often not caused by lack of effort but by gaps in knowledge and execution. Despite longstanding guidance, inconsistencies in cleaning and disinfection practices continue to be cited during regulatory and accrediting surveys.
