Optimizing intensive care unit (ICU) admissions can save lives. A new model shows that prioritizing patients with a survival benefit of at least 19.4% could save 18 more lives annually compared to standard policies.

Area of Science:

  • Healthcare Management
  • Operations Research
  • Critical Care Medicine

Background:

  • Intensive care units (ICUs) face challenges in optimizing patient admissions to maximize life-saving impact.
  • Queueing theory provides a framework for modeling patient flow and resource allocation in critical care settings.

Purpose of the Study:

  • To develop and evaluate a model for optimizing ICU admissions to maximize the expected number of lives saved.
  • To compare the effectiveness of different admission policies, including First Come First Served (FCFS), FCFS with a hurdle (FCFS-H), and FCFS with a bed-specific hurdle (FCFS-BSH).

Main Methods:

  • Utilized queueing theory to model the probability distribution of occupied ICU beds.
  • Applied the model to patient referral data from a specific hospital ICU.

  • Statistically estimated the distribution of expected incremental survival benefits for referred patients.

    • Main Results:

    • Implementing an FCFS-H policy with a 19.4% survival benefit threshold could save an additional 18 statistical lives annually (17.9% improvement) compared to FCFS.
    • The FCFS-BSH policy offered a marginal additional benefit of 1.4 statistical lives annually (1.2% improvement) over FCFS-H.

    Conclusions:

    • Optimizing ICU admissions based on predicted survival benefits can significantly increase lives saved.
    • A hurdle-based admission policy demonstrates superior effectiveness in maximizing life-saving potential within ICUs.
