An infection preventionist has been asked to participate in a process improvement team to standardize...

In quality improvement, a baseline measurement is collected before implementing changes so the team can compare performance over time and determine whether interventions produced improvement. Creating the baseline after changes are implemented defeats the purpose of baseline data because it removes the “pre-intervention” reference point needed to evaluate impact and sustainment. Quality improvement measurement guidance emphasizes capturing a baseline and then continuing measurement at regular intervals to judge the effect of an intervention.

The other activities listed are appropriate for standardizing disinfection and sterilization practices. Direct observation (A) is a common process-assessment method to identify gaps between policy and actual practice. Including central sterile/central supply and OR leaders (B) supports multidisciplinary engagement and ensures changes are operationally feasible where reprocessing occurs. Performing a literature and guidance review (C) helps align local practice with authoritative recommendations (e.g., CDC disinfection/sterilization guidance and monitoring expectations).
