Variable costs of ICU patients: a multicenter prospective study.

Area of Science:

• Health Economics
• Critical Care Medicine
• Healthcare Management

Background:

• Intensive care unit (ICU) treatment costs represent a substantial portion of healthcare expenditure.
• Understanding cost variations is crucial for resource allocation and financial planning in critical care settings.

Purpose of the Study:

• To analyze and quantify the variable costs associated with treating critically ill patients across different diagnostic groups.
• To identify factors influencing cost variations and assess cost-efficiency in an ICU setting.

Main Methods:

• A multicenter, observational, prospective, cohort, bottom-up study was conducted in 51 ICUs.
• Data on 1,034 adult patients were collected, including length of ICU stay and detailed costs of procedures, drugs, equipment, and consultations.
• Cost-efficiency metrics, such as cost per surviving patient and money loss per patient, were calculated.

Main Results:

• Median treatment costs varied widely, with multiple trauma patients costing €4076 and coronary surgery patients €380.
• Cost per surviving patient was highest for acute lung injury/adult respiratory distress syndrome (ALI/ARDS) and multiple trauma.
• Planned surgeries and shorter ICU stays demonstrated higher cost-efficiency.

Conclusions:

• Significant variability exists in ICU treatment costs, influenced by patient diagnosis and length of stay.
• High costs and low cost-efficiency are observed in specific patient groups, necessitating targeted management strategies.
• Developing strategies to control major cost determinants is essential for optimizing ICU resource utilization.
