Insights
Evaluating adult cardiac surgery quality requires risk adjustment. The French-score demonstrated the best correlation between risk groups and mortality, proving reliable for assessing surgical care quality.
Area of Science:
- Cardiovascular Surgery
- Healthcare Quality Assessment
- Medical Statistics
Background:
- Quality of care assessment in adult cardiac surgery necessitates risk adjustment.
- Several international risk stratification scores have been developed over the past decade.
Purpose of the Study:
- To prospectively compare the performance of three prominent risk stratification scores: Parsonnet, Higgins, and French-score.
- To determine which score best correlates incremental risk groups with patient mortality in cardiac surgery.
Main Methods:
- Prospective study design.
- Inclusion of Parsonnet, Higgins, and French-score for comparison.
- Analysis of correlation between risk groups defined by each score and observed mortality.
Main Results:
- The French-score exhibited the strongest correlation between incremental risk groups and mortality.
- The French-score was found to be reliable due to its use of easily obtainable risk factors.
- The score's limited number of risk groups contributed to its reliability.
Conclusions:
- The French-score is a reliable and effective tool for risk-adjusted quality assessment in adult cardiac surgery.
- Its ease of use and strong correlation with mortality make it superior to the Parsonnet and Higgins scores for this purpose.
Abstract:
Assessment of quality of care in adult cardiac surgery is only adequate if done in a risk adjusted manner. Over the last 10 years a number of risk stratification scores have been established internationally. This prospective study compares three important and widespread scores, the Parsonnet-, the Higgins-, and the French-score. Correlation between incremental risk groups and mortality was best achieved with French-score. The score was reliable due to easily available risk factors and a small number of risk groups.
