Summary
Comparing adult intensive care unit costs is unreliable due to flawed costing methodologies across studies. Methodological bias and inadequate study design prevent accurate cost comparisons in intensive care therapy.
Area of Science:
- Health Economics
- Critical Care Medicine
Background:
- Costing hospital services is complex, especially in adult intensive care units (ICUs).
- Previous studies on ICU costs exhibit significant variability and methodological challenges.
Purpose of the Study:
- To critically evaluate methods for costing adult intensive care unit services.
- To assess the comparability of cost data across multiple published ICU studies.
Main Methods:
- Systematic review of 20 published English-language cost studies of adult intensive care units.
- Analysis of costing approaches, case-mix, severity-of-illness, outcome, and resource utilization.
Main Results:
- Significant methodological biases identified due to diverse costing approaches.
- Costing methodologies were often mis-specified regarding study purpose and viewpoint.
- Inadequate study questions and non-tailored cost concepts were prevalent.
Conclusions:
- Current methodologies for costing intensive care unit therapy are fundamentally flawed.
- Direct cost comparisons across different adult ICUs are not feasible with existing data.
- There is a critical need for standardized and appropriate costing methodologies in ICU research.
