This study examines how multidisciplinary collaboration among emergency, clinical, and administrative professionals influences patient outcomes and overall hospital performance. Focusing on real-world interactions in acute care settings, it analyzes communication patterns, decision-making processes, and coordinated workflows that bridge clinical and non-clinical roles. By mapping how emergency physicians, nurses, allied health staff, and administrators share information and align priorities during care transitions, the research identifies which collaborative behaviors are most strongly associated with reduced length of stay, lower readmission rates, and improved patient safety metrics. The study also considers contextual factors—such as staffing levels, electronic health record (EHR) integration, and leadership support—that enable or hinder effective teamwork. Using a mixed-methods design, the study combines quantitative performance indicators with qualitative data from interviews, focus groups, and direct observations to generate a comprehensive picture of interprofessional practice. Statistical analyses correlate specific collaborative interventions (for example, structured handoff protocols or interdisciplinary rounds) with measurable improvements in efficiency and clinical outcomes, while thematic analysis reveals perceived barriers like role ambiguity, time pressure, and cultural silos. The findings aim to inform practical recommendations for training, workflow redesign, and policy changes that strengthen multidisciplinary collaboration and, in turn, enhance hospital resilience, patient experience, and operational sustainability.
