Abstract

Risk assessment tools are increasingly used in surgery. In cardiac surgery, risk models are used for patient counselling, surgical decision-making, performance benchmarking, clinical research, evaluation of new therapies and quality assurance, among others. However, they have numerous disadvantages which need to be considered. This article evaluates the utility of risk assessment tools in cardiac surgery including a discussion of their advantages and disadvantages.

Abstract

Cardiac surgery has embraced and encouraged the use of large, multi-institutional datasets in clinical practice. From a research perspective, database studies have facilitated an increased understanding of cardiac surgery. Among other uses, they have allowed an investigation of disease incidence and mortality, high risk groups, disparities in health care delivery and the impact of new devices and techniques. Databases are also important tools for clinical governance and quality improvement. Despite their obvious utility, clinical databases have limitations; they are subject to treatment bias, contain missing data and cannot establish causality. Moreover, the ongoing maintenance of the database requires significant human and financial resources. In the future, inclusion of more detailed follow-up data and integration with other datasets will improve the utility of clinical databases.
