Why the study?

Does the APACHE II scoring system accurately predict mortality in cardiothoracic surgical patients?

Key Points

To evaluate the predictive performance of the APACHE II scoring system for mortality among patients recovering from cardiothoracic surgery.
Prospective survey tracking 811 consecutive cardiothoracic surgical patients admitted to a tertiary referral cardiothoracic ICU through hospital discharge.
Collected demographic and physiological parameters to calculate APACHE II scores and compare predicted risk against observed ICU mortality.
The overall predicted risk of dying was 4.59% compared to an observed ICU mortality rate of 4.56%, demonstrating a significant linear relationship (p < 0.001).
Mortality was 0.93% for patients with an APACHE II score below 10, whereas scores above 30 were uniformly fatal (n = 1).
Emergency surgery, a history of chronic disease, and prolonged ICU stay served as significant markers of increased mortality.

Structured PICO

Does the APACHE II scoring system accurately predict mortality in cardiothoracic surgical patients?

P

Population

811 cardiothoracic surgical patients admitted to a cardiothoracic surgical ICU in a tertiary referral center, mean age 57 years.

I

Intervention

APACHE II scoring system

O

Outcome

ICU mortality ratehard clinical

The APACHE II score accurately predicts survival at low scores but only very high scores accurately predict death in cardiothoracic surgical patients.

Implication

Supports APACHE II calibration in cardiothoracic surgical ICU patients; leaves open discrimination for individual prognostication.
