IQCE Policy Brief No. 8, August 2020: "A methodological approach to aggregate multiple measures of hospital quality using variance-based weights" by Angela Meggiolaro
Key Findings
• The composite index specifies an indirect measure of hospitals’ performance.
• The Accelerated Failure Time system of regressions is more efficient compared with the widely used generalized linear models (GLM) that rely on dichotomized data.
• Variance weights elicitation is data driven and less exposed to bias of normative approaches.
• Risk adjustment and acute cardio vascular events (CVE) prevent selection bias and “cherry picking”.
