Project summary

Background

The Dr Foster Unit at Imperial makes several key contributions to the project which is facilitated by Dr Foster Intelligence. At the beginning, we advised on the data processing (e.g. determining what is an inpatient and defining the procedure groups) and ran the initial risk-adjustment models. More recently, we advised on the method for comorbidity adjustment and assessed the impact on the variation by country in mortality rates of different coding patterns and denominator inflation. We have also provided documentation around the methods used and have led the writing of two draft research papers to date. We are represented on the project’s Scientific and Research Committee. We will continue to work on indicators, risk-adjustment models and data presentation. More information on the work being carried out can be found on the Global Comparators website.

Aims
