Allocation Algorithm for Optimized Regional Acute Stroke Care

Medical Need

Acute stroke care requires rapid and efficient allocation of patients to appropriate hospitals to ensure timely access to life-saving treatments like thrombolysis and endovascular therapy. Inefficient allocation leads to treatment delays, worsened clinical outcomes, increased mortality, and higher economic costs. Optimizing patient transport pathways is essential to improve resource utilization and patient outcomes in stroke networks.

Aim of Project

The aim of the project is to develop a decision support algorithm to optimize the allocation of acute stroke patients to hospitals. By analyzing transport scenarios and preclinical data, the algorithm will provide real-time recommendations to minimize delays, improve clinical outcomes, and enhance the efficiency of resource utilization in emergency stroke care.

Optimizing acute stroke care through data-driven patient allocation

The ARAS project focuses on improving acute stroke care by developing a decision-support algorithm that optimizes patient allocation. In Eastern Saxony, stroke is a leading cause of death and disability, with a population that faces challenges due to sparse hospital coverage and limited resources. Inefficient allocation of patients often results in delayed treatment, higher mortality rates, worse clinical outcomes, and increased economic costs. The project will analyze current transport pathways using simulation tools, incorporating real-world data on preclinical patient status, transportation duration, and hospital treatment capacities. These simulations will reveal inefficiencies in the existing system and help model optimized allocation strategies.

The core outcome of ARAS is an algorithm that supports first responders in selecting the most appropriate hospital for each patient based on transport times and available treatment options, such as CT imaging, endovascular therapies, and specialized care units. A web-based prototype will be developed to provide real-time, transparent recommendations. Additionally, ARAS will evaluate the economic impact of optimized resource allocation, addressing treatment delays, unnecessary transfers, and limited rescue service availability. The project not only aims to enhance the efficiency of acute stroke care but also to improve overall patient outcomes, particularly in aging and underserved regions.

Future potential includes scaling the algorithm for broader regional applications, such as neighboring states, and adapting it for other medical emergencies like heart attacks or trauma care. The project will serve as a foundation for advanced machine-learning tools and further clinical studies, contributing to sustainable and optimized healthcare delivery in emergency scenarios.
