Interprofessional Collaboration in Emergency Care: A Systems Approach Integrating Pharmacy, Radiology, Health Informatics, Nursing, and Medical Sterilization

Abstract

Emergency departments (EDs) are complex, high-risk environments where patient outcomes depend on rapid, coordinated work across multiple professions. A systems approach to interprofessional collaboration recognizes that pharmacy, radiology, health informatics, nursing, and medical sterilization (central sterile services) form an interconnected network rather than isolated departments. Evidence shows that interprofessional teamwork improves quality of care, reduces medication errors, enhances antimicrobial stewardship, improves imaging safety and communication, and strengthens infection prevention and control. This paper applies a systems lens to describe how these five disciplines contribute to safe, effective emergency care and how their collaboration can be intentionally designed. The body of the paper (1) outlines key roles and evidence for impact in each profession, (2) proposes a socio-technical systems model for ED collaboration, and (3) presents practical strategies for implementation, supported by tables and conceptual figures. The paper concludes with specific recommendations on shared governance, digital infrastructure, joint training, and standardized workflows that support interprofessional practice.
