Prolonged stay in intensive care unit is a powerful predictor of adverse outcomes after cardiac operations

Area of Science:

• Critical Care Medicine
• Surgical Outcomes Research
• Patient Prognosis

Background:

• Understanding the implications of extended intensive care unit (ICU) stays is crucial for surgical patient management.
• Previous research has indicated potential negative associations between prolonged ICU duration and patient outcomes.

Purpose of the Study:

• To investigate the impact of prolonged intensive care unit (ICU) stay on in-hospital mortality and long-term survival following surgical procedures.
• To identify prolonged ICU stay as a predictor of adverse outcomes.

Main Methods:

• Analysis of prospectively collected data from 6,101 surgical patients (2003-2007).
• Definition of prolonged ICU stay as ≥3 days postoperatively, with <3 days as controls.
• Utilized univariate and multiple variable analyses to identify risk factors and predictors.

Main Results:

• 18.7% of patients experienced prolonged ICU stays, showing significantly higher ICU and hospital mortality rates compared to controls.
• Patients with prolonged ICU stays had substantially lower 1-year and 3-year survival rates post-discharge.
• Prolonged ICU stay was identified as an independent predictor of prolonged hospital stay, increased mortality, and poorer long-term survival.

Conclusions:

• Prolonged intensive care unit (ICU) stay is a significant predictor of adverse outcomes.
• This includes immediate, short-term, and long-term negative impacts on patients undergoing cardiac operations.
• The findings underscore the importance of minimizing prolonged ICU stays to improve surgical patient prognosis.
