Summary

High-risk volume and appropriate occupancy rates in intensive care units (ICUs) significantly reduce patient mortality. Cost-effectiveness varies, with some conditions being less efficient users of ICU resources.

Area of Science:

  • Critical Care Medicine
  • Health Services Research
  • Healthcare Management

Background:

  • Optimizing Intensive Care Unit (ICU) resource utilization is crucial for patient outcomes and cost-effectiveness.
  • Existing metrics may not fully capture the nuances of ICU activity volume and its impact on mortality.
  • Understanding cost-effectiveness and nursing resource allocation is essential for efficient ICU operations.

Purpose of the Study:

  • To investigate the relationship between ICU activity volume and patient mortality.
  • To analyze the cost-effectiveness of intensive care medicine across different patient groups.
  • To develop and test a novel method for monitoring nursing resource utilization in ICUs.

Main Methods:

  • Utilized three surveys: European, country-level, and regional.

  • Developed a "high-risk volume" metric to assess the relationship between activity volume and patient outcomes.
  • Analyzed national case-mix data for cost-effectiveness and implemented a new approach for daily nursing resource use measurement.

    • Main Results:

    • A strong association was found between high-risk volume and decreased ICU/hospital mortality (3-1719% reduction per five extra high-risk patients/bed/year).
    • Occupancy rates exceeding 80% were linked to increased mortality.
    • Certain patient groups (brain hemorrhage, ALI/ARDS, unscheduled surgery) were less cost-efficient, while scheduled abdominal surgery and minor organ support patients were more efficient.

    Conclusions:

    • Patients benefit from treatment in high-risk volume ICUs with optimal occupancy rates (<=80%).
    • Targeted interventions are needed to improve cost-efficiency for specific patient diagnoses.
    • The developed method effectively measures and distinguishes between over- and under-utilization of nursing resources in ICUs.
