Summary
Demand for critical care and high-dependency beds is rising, especially for elderly surgical patients. Audits show improved mortality rates, particularly for ventilated patients, indicating a need for future bed planning.
Area of Science:
- Critical Care Medicine
- Surgical Outcomes
- Healthcare Management
Background:
- Increasing elderly population undergoing major surgery drives demand for critical and high-dependency care.
- Stratified patient care models necessitate specialized bed allocation.
- Combined Intensive Care and High-Dependency Units (ITU/HDU) manage complex patient needs.
Purpose of the Study:
- To audit the activity and outcomes of a combined ITU/HDU over a decade.
- To compare patient admission trends and mortality rates between 1981 and 1991.
- To predict future demand for critical and high-dependency beds based on current trends.
Main Methods:
- Comparative audit of ITU/HDU activity and patient outcomes.
- Analysis of patient admission numbers and mortality data for 1981 and 1991.
- Trend analysis to forecast future bed requirements for a defined population.
Main Results:
- Significant increase in patient admissions to ITU/HDU, particularly for high-dependency care.
- Overall mortality decreased from 12% in 1981 to 9.5% in 1991.
- Mortality for ventilated patients dramatically reduced from 54% (1981) to 30% (1991).
Conclusions:
- Current trends suggest a continued rise in demand for critical and high-dependency care beds.
- Future planning indicates a need for separate but adjacent ITU and high-dependency surgical units.
- A projected requirement of six ITU beds and eight high-dependency surgical beds is identified, emphasizing skill interchange.
