Challenges to Integrating Portable Magnetic Resonance Imaging Systems in Emergency Medical Service Ambulances for Stroke Care

Abstract

This qualitative study explores the barriers to incorporating portable MRI devices in ambulances, enabling effective patient triage and potentially reducing time to thrombolytic treatment for stroke. Using a digital twin of the patient handling process, semi-structured interviews were conducted with 11 paramedics and 7 neurologists from an emergency medical services system and a tertiary stroke care center. Thematic analysis of interview transcripts, guided by the Systems Engineering Initiative for Patient Safety framework, revealed key barriers: the need for specialized MRI operation skills, complex patient handling procedures, limited space, and the necessity for training and policy development. The study proposes solutions to address these challenges, aiming to facilitate the implementation of ambulance-based MRI systems for expedited stroke care. The findings contribute to understanding the factors influencing the adoption of advanced imaging technology in pre-hospital settings, ultimately improving patient outcomes by minimizing delays in stroke treatment.
