Policy Proposals for Mitigating Intensive Care Unit Strain: Insights from the COVID-19 Pandemic

Area of Science:

• Critical care medicine
• Health services research
• Public health policy

Background:

• Intensive care unit (ICU) strain, a mismatch between resource demand and availability, negatively affects patient outcomes and healthcare worker well-being.
• The COVID-19 pandemic significantly amplified ICU strain, contributing to increased mortality and prolonged hospitalizations for both COVID-19 and non-COVID-19 patients.

Purpose of the Study:

• To systematically review and identify key indicators of ICU capacity strain.
• To evaluate the limitations of existing indicators for strategic planning and policy development.
• To advocate for policies and regional cooperation to enhance ICU resilience and resource management during crises.

Main Methods:

• A systematic review was conducted to identify leading and lagging indicators of ICU capacity strain.
• The review analyzed 16 distinct indicators, including queuing, discharge timing, space utilization, length of stay, staffing ratios, patient acuity, mortality, readmissions, supply availability, ventilator use, and surgery cancellations.
• The study assessed the operational definitions, reliability, validity, usability, and feasibility of these indicators.

Main Results:

• Sixteen indicators of ICU strain were identified, encompassing operational, patient flow, staffing, and resource availability metrics.
• Significant variability in operational definitions and limited evidence on the psychometric properties of single indicators were noted, hindering their utility for strategic planning.
• The need for enhanced real-time monitoring, interhospital transfers, and comprehensive resilience strategies was highlighted.

Conclusions:

• Effective management of ICU strain necessitates robust regional and national policies for real-time monitoring and resource allocation.
• Proactive regional cooperation is crucial for policy formulation, knowledge sharing, and resource distribution to mitigate strain during health crises.
• Future preparedness requires evidence-based triage, adaptable patient management, ethical resource allocation, and behavioral economic insights to ensure health equity and system resilience.
