Exploring the Management of the Triage System in the Screening of Patients: The Case of Emergency Health Services in Portugal

Introduction: This study examines the effectiveness and management of triage systems, particularly the Manchester Triage System (MTS), in Portuguese emergency services. It explores the extent to which current screening practices align with the goals of prioritising critical patients and managing limited healthcare resources efficiently.Methods: A qualitative research design was adopted, using semi-structured interviews with healthcare professionals working in emergency departments in Portugal. Thematic analysis was conducted to compare frontline experiences with theoretical insights from the existing literature, enabling a contextual assessment of the MTS’s operational effectiveness.Results: The Manchester Triage System was generally perceived as valid and functional. However, professionals reported challenges such as delayed diagnostic procedures, lack of material resources, and inconsistent adherence to triage priorities. Key suggestions included refining workflow structures, improving digital systems, and strengthening nurse training in Basic and Advanced Life Support.Conclusions: Reorganising emergency departments—by more clearly separating high- and low-priority cases, improving staff allocation, and enhancing IT infrastructure—can reduce waiting times, improve patient flow, and increase clinical safety. These changes may enhance patient satisfaction, reduce inequalities in emergency care delivery, and mitigate burnout among healthcare professionals.
