Expert consensus vs empirical estimation of injury severity: effect on quality measurement in trauma.
OBJECTIVE To determine the extent to which the Injury Severity Score (ISS) and Trauma Mortality Probability Model (T-MPM), a new trauma injury score based on empirical injury severity estimates, agree on hospital quality. DESIGN, SETTING, AND PATIENTS Retrospective cohort study based on 66,214 patients in 68 hospitals. Four risk-adjustment models based on either ISS or T-MPM were constructed,...
متن کاملExpert opinion vs. empirical evidence
Expert opinion is often sought by government regulatory agencies when there is insufficient empirical evidence to judge the safety implications of a course of action. However, it can be reckless to continue following expert opinion when a preponderance of evidence is amassed that conflicts with this opinion. Factual evidence should always trump opinion in prioritizing the information that is us...
متن کاملConsensus or data-derived anatomic injury severity scoring?
BACKGROUND Anatomic injury severity scores can be grouped into two classes; consensus-derived and data-derived. The former, including the Injury Severity Score (ISS), the New Injury Severity Score (NISS), and the Anatomic Profile Score (APS), are based on the severity score of the Abbreviated Injury Scale (AIS), assigned by clinical experts. The latter, including the International Classificatio...
متن کاملThe Injury Brokers: an Empirical Profile of Medical Expert Witnesses in Personal Injury Litigation
[In the civil justice system, medical expert witnesses act as brokers of what qualifies as legally recognised and compensable injury. Despite the central importance of their role, and continuing debate over the use of expert evidence, remarkably little empirical evidence is available about who medical experts are and what they do. This article reports findings from a study that built a detailed...
متن کاملMerging expert and empirical data for rare event frequency estimation: Pool homogenisation for empirical Bayes models
Empirical Bayes provides one approach to estimating the frequency of rare events as a weighted average of the frequencies of an event and a pool of events. The pool will draw upon, for example, events with similar precursors. The higher the degree of homogeneity of the pool, then the Empirical Bayes estimator will be more accurate. We propose and evaluate a new method using homogenisation facto...
