Abstract | In this work we propose the use of a graphical diagnostic tool (the funnel
plot) to detect outliers among hospitals that treat patients affected by Acute
Myocardial Infarction (AMI). We consider an application to data on AMI hospitalizations
arising from administrative databases. The outcome of interest is the in-hospital mortality, a variable indicating if the patient has been discharged dead or alive. We then compare the results obtained by graphical diagnostic
tools with those arising from fitting parametric mixed effects models to the same data. |
