Abstract:
Risk-adjusted charts for monitoring a surgical or patient care process have recently gained prominence in the literature. To monitor a patient care process, especially to detect deterioration is crucial in saving patients' lives. In this paper, a new charting procedure is developed for monitoring a patient care process for patients admitted to a hospital with acute myocardial infarctions. This procedure is based on the number-between failures by taking the patients' risks into account. When there is a change in the risk distribution of incoming patients, it is demonstrated that this procedure will behave properly while the non-risk-adjusted counterpart will signal incorrectly that the patient care process has changed. The setting up of this chart to monitor a patient care process for patients with acute myocardial infarctions is described in detail.

The X̄ Chart
The x̄ chart, often known as the individual control chart, is a crucial tool in statistical process control. It is designed to monitor process behavior and performance over time and is widely used in various industries to ensure that processes are operating at their optimum capacity and within specified limits.
A x̄ chart is constructed by plotting individual measurements of a quality characteristic in the order in which...
