At NUHS, research strengthens the foundations of Appropriate and Value-Based Care (AVBC). It supports how we improve care, guide decisions and sustain impact in practice. To generate evidence that informs better care and better decisions, our research is shared through evaluations, conference presentations, and peer-reviewed publications. This contributes to the growing body of knowledge in valued-based healthcare in Singapore and globally.
Our work translates data into actionable insights. It supports care redesign, guides clinical and operational decisions, and advances understanding of how appropriate, patient-centred care creates value.
