Abstract.The monitoring and detection of Hospital acquired infections (HAI) is a very important problem arising in hospitals. A hospital acquired or nosocomial infections is a disease that develops after admission into the hospital and it is the consequence of a treatment, not necessarily a surgical one, performed by the medical staff. This paper provides an overview of SPC and few practical examples of HAI monitoring control charts. The application of Shewhart, cumulative sum (CUSUM) and exponentially weighted moving average (EWMA) statistical process control charts are also discussed. This work can help both researchers and practitioners of quality improvement to determine weather the changes in process are making a real difference in outcome.
