A Case Study in Monitoring Hospital-Associated Infections with Count Control Charts

Summary: [This abstract is based on the authors' abstract.] Hospital-associated infections are a major concern in the medical community, but traditional methods of analysis are often inadequate. It is shown here how the cumulative sum (CUSUM) chart for counted data and the g-type chart may be applied to infection control surveillance data from a children’s hospital. Recommendations are made for a control chart most suitable for monitoring these types of infection.
