An Observational Evaluation of Characteristics of Participants in Clinical

The aim of this study is to evaluate whether females are underrepresented in clinical studies in the Departments of Anaesthesia and Intensive Care, Amsterdam UMC, locations AMC and VUmc. The main outcome is Participation Prevalence Ratio (PPR), which means the representation of female/male patients in a study in relation to their representation in the disease population undergoing surgery.

To achieve this, we will use the average proportion of female participants enrolled per study and, in addition, data from the CBS for population benchmarking, determining the proportions of males and females undergoing surgery (elective cardiac and non-cardiac surgery) and the proportions of these populations in an academic hospital.
