What is the clinical evidence from this study?

Study design: Cohort. Population: Patients undergoing elective surgery (n=16227). Intervention: ASA grade and Goldman's cardiac risk index. Primary outcome: Peri-operative mortality within 4 weeks of operation.

What does this research mean for the field?

Both the ASA physical status classification and Goldman's cardiac risk index significantly predict peri-operative mortality in elective surgery patients, with the ASA grade showing a stronger correlation and their combination yielding the highest predictive accuracy. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

This study aims to evaluate the effectiveness of ASA grade and Goldman's cardiac risk index in predicting peri-operative mortality in elective surgery.

Key result

ASA grade and Goldman's cardiac risk index significantly predicted peri-operative mortality, with mortality ranging from 0.4% in the lowest risk subgroup to 7.3% in the highest risk subgroup.

Why the study?

Does ASA grade or Goldman's cardiac risk index predict peri-operative mortality in patients undergoing elective surgery?

Key Points

This study aims to evaluate the effectiveness of ASA grade and Goldman's cardiac risk index in predicting peri-operative mortality in elective surgery.
Evaluated 16,227 patients scheduled for elective surgery over a 5-year period.
Patients were scored using ASA grade and Goldman cardiac risk index pre-operatively.
Performed a regression tree analysis to identify mortality risk subgroups.
Overall, 215 patients died within 4 weeks post-operation.
Mortality was 0.4% in ASA grade <= 2 and cardiac risk index group I (score 0-5 points).
Mortality increased to 7.3% in ASA grade = 4 and cardiac risk index group >= 3 (score > 13 points).

The combination of ASA grade and Goldman's cardiac risk index accurately predicts peri-operative mortality in patients undergoing elective surgery.

Implication

May aid elective surgery risk stratification; leaves open need for prospective outcome validation.

Prause et al. (1997) conducted a cohort in Patients undergoing elective surgery (n=16,227). ASA grade and Goldman's cardiac risk index was evaluated on Peri-operative mortality within 4 weeks of operation. ASA grade and Goldman's cardiac risk index significantly predicted peri-operative mortality, with mortality ranging from 0.4% in the lowest risk subgroup to 7.3% in the highest risk subgroup.
