Monitoring surgical performance using risk-adjusted cumulative sum charts.
The cumulative sum (CUSUM) procedure is a graphical method that is widely used for quality monitoring in industrial settings. More recently it has been used to monitor surgical outcomes whereby it 'signals' if sufficient evidence has accumulated that there has been a change in the surgical failure rate. A limitation of the standard CUSUM procedure in this context is that since it is simply base...
متن کاملMonitoring binary outcomes using risk-adjusted charts: a comparative study.
Monitoring binary outcomes when evaluating health care performance has recently become common. Classical statistical methodologies such as cumulative sum (CUSUM) charts have been refined and used for this purpose. For instance, the risk-adjusted CUSUM chart (RA-CUSUM) for monitoring binary outcomes was proposed for monitoring 30-day mortality following cardiac surgery. The RA-CUSUM inherits opt...
متن کاملRisk-Adjusted Control Charts for Health Care Monitoring
Attribute data from high quality processes can be monitored effectively by deciding on whether or not to stop at each time where r ≥ 1 failures have occurred. The smaller the degree of change in failure rate during Out-of-Control one wants to be optimally protected against, the larger r should be. Under homogeneity, the distribution involved is negative binomial. However, in health care monitor...
متن کاملMonitoring vaccine safety using case series CUSUM charts
We adapt the self-controlled case series method for long-term surveillance of vaccine safety using cumulative sum (CUSUM) charts. The CUSUM surveillance method we propose is applicable for detecting associations that arise in a short pre-determined risk period following vaccination. The performance of the case series CUSUM is investigated through simulations. We illustrate the method using retr...
متن کاملA risk-adjusted O-E CUSUM with monitoring bands for monitoring medical outcomes.
In order to monitor a medical center's survival outcomes using simple plots, we introduce a risk-adjusted Observed-Expected (O-E) Cumulative SUM (CUSUM) along with monitoring bands as decision criterion.The proposed monitoring bands can be used in place of a more traditional but complicated V-shaped mask or the simultaneous use of two one-sided CUSUMs. The resulting plot is designed to simultan...
