What is indicated by ongoing MDRO transmission despite control efforts?

Continuing transmission of multidrug-resistant organisms (MDRO) even after implementing control measures signifies that additional strategies may be necessary to halt the spread of these organisms. This situation often indicates that existing isolation protocols may not be sufficient, or that further escalation of infection control practices might be required to protect residents. Increased isolation measures can help to contain the outbreak by reducing opportunities for transmission, particularly in high-risk areas such as nursing homes where vulnerable populations reside.

In contrast, the notion that all patients are free of MDRO is incorrect, as ongoing transmission clearly suggests the opposite. The adherence of staff to hygiene protocols might be an essential factor in infection control, but the presence of ongoing transmission highlights potential gaps or challenges in these practices, rather than confirming their effectiveness. Lastly, while higher levels of resident mobility can contribute to the spread of infections, the key takeaway in the context of control efforts is that more comprehensive isolation measures are necessary when MDROs continue to spread despite existing interventions.
