Research Synopsis

Our profession is continually evolving. In an era of dynamic change, how should pharmacist adapt? What is our role? What should we do to make the biggest impact? The emergency department (ED) is the frontline for provision of medical care. It is also the safety net of our health-system, especially for those who seek immediate care but lack routine primary care. In order to expand our value and more importantly, channel the value our profession brings to the public, the ED is a great environment to demonstrate the value of the pharmacist. In an inherently fast-paced environment usually defined by high patient volume, complex clinical acuity, and limited resource, our research focuses on investigating the feasibility and practicality of services and practices that the pharmacist may provide to improve patient care. In addition to conducting research to expand pharmacy practice in the ED, we also conduct research to find innovative, safe, and effective therapies to manage pain in the acute and critical setting. Pain is the most common reason for patient visits to the ED. As the drug expert, pharmacist has the knowledge, skills, and ability to make innovative changes to standard practice and how pain is managed in an acute setting.
