Deaths in intensive care: analysis and prediction

Area of Science:

• Critical Care Medicine
• Intensive Care Unit (ICU) Studies
• Prognostic Factor Analysis

Background:

• Analysis of critically ill (grade IV) patients admitted to Flinders Medical Centre's intensive care unit (ICU) between 1977 and 1978.
• High mortality rates observed in this patient cohort.

Purpose of the Study:

• To analyze outcomes and identify predictors of mortality in critically ill ICU patients.
• To evaluate the utility of disease state, coma, and renal failure as prognostic indicators.
• To investigate causes of death and the cessation of life support in ICU patients.

Main Methods:

• Retrospective data analysis of grade IV critically ill patients.
• Identification of patient characteristics, disease states, and clinical signs.
• Analysis of causes of death and life support decisions.

Main Results:

• Mortality rates were 37% in 1977 and 32% in 1978.
• No absolute predictors of outcome were identified.
• Disease state, coma, and renal failure were useful prognostic guides.
• Cardiovascular system failure (51%) and central nervous system failure (28%) were the primary causes of death.
• Life support was ceased in 28 patients, 15 without brain death.

Conclusions:

• Early aggressive investigation and management are essential for critically ill ICU patients.
• Prognostic guidance can be derived from disease state, coma, and renal failure.
• Standardized data reporting is needed for comparative analysis of ICU outcomes.
• Criteria for cessation of life support require careful consideration, especially in non-brain-dead patients.
