Agreement between three perioperative risk scores

Concordância entre três escores de risco perioperatório

SUMMARY

Objective:

To evaluate the agreement between the three scores proposed by the II Guideline for Perioperative Evaluation of the Brazilian Society of Cardiology (SBC): the American College of Physicians algorithm (ACP), the Multicenter Study of Perioperative Evaluation (EMAPO) and Lee’s Revised Cardiac Risk Index (RCRI).

Method:

Patients evaluated preoperatively for non-cardiac surgery by the anesthesiology service were classified as low, moderate or high-risk according to the 3 algorithms suggested by the II Guideline. To calculate the strength of agreement between the scores, the kappa agreement index was used.

Results:

Four hundred and one patients were included in the sample. Cohen’s kappa inter-rater agreement between scores was 0.270 (CI: 0.222 to 0.318), corresponding to a weak agreement. Analyzing in pairs, the best correlation was between EMAPO and ACP, with kappa = 0.327. Lee’s score was the one that classified more patients as low-risk: 98.3%, while EMAPO and ACP classified as low risk 91.3% and 92.5%, respectively.

Conclusion:

There is poor correlation among the risk scores proposed by the II Perioperative Evaluation Guideline of the SBC.
