Abstract

Statistical process control should play a central role in all infection prevention programs. Unless one has sufficient training in statistical methods, collecting the correct data and generating appropriate graphics to summarize them can be difficult. Through proper data collection and critical analysis of control charts, the infection preventionist can detect abnormalities in infection rates quickly, which facilitates prompt changes to processes that will yield desirable outcomes.
