Can cross-contamination be avoided?
(7) Problem: As a cost-saving measure, some respiratory therapy departments have been using a single metered dose inhaler (MDI) canister to administer medication to multiple patients. Proponents cite significant cost savings, efficiency, and fewer treatment delays, while advocating that cross-contamination is unlikely if the nozzle is disinfected. Although studies have shown both positive and negative results regarding cross-contamination, opponents of the practice are not convinced that the benefits outweigh the risk. Recommendation: Carefully consider the risks and benefits if your facility is deciding whether to implement a common MDI protocol. If implemented, the Association for Professionals in Infection Control and Epidemiology (APIC) recommends carefully analyzing your processes to ensure handoffs between patients are not inadvertent sources of contact transmission, and emphasizing in the protocol the importance of hand hygiene and canister disinfection with alcohol after each u
