MinimumCombinedCodes =2; is that because we will require coding of a pathogen? If so then BugRequired= needs to be 2. Also we will need to decide whether this should be in the category infections after all. Cross checks may depend on this. Also infection template may need to be added.

  • There ARE lots of other bugs that can colonize various parts of the body, almost all of which CAN also cause infection. There is a smallish list of bugs that NEVER colonize and are always believed to be active infectious agent, e.g. Mycobacterium TB, Legionella, Ebola, SARS-2 (i.e. COVID-19).

Colonization

You can use the "set MRSA Colonized" button to enter the following:

Infection

Combined code the following

  • the appropriate code from one of the following
Infection requiring pathogen codes:
Potential infection codes:

Colonized vs local infection

  • If MRSA drawn from an abscess or deep in wound and you think it is causing the "local" infection, else code colonization.

Data Use

Julie reported in 2013 that in the past 2 years there were 2 requests for data related to these variables.

  • Not required as it is still not nearly as common as MRSA. The same rule applies for determining if it is an active infection for all of the colonized organisms, this is within the MRSA template localized infection vs colonization.

Colonizations are not attributed to any units

We don't have any reports that attribute colonization to any units, so Attribution of infections doesn't apply.
