The medical care model must move from an analog model based on the paper process to a digital model where HCIT supports a redesigned model of care. There is no ROI on investment in EMRs unless the data in the EMR are leveraged to re-engineer care to improve quality and outcomes. These future state care models must be knowledge-driven. The focus must be towards outcomes and value with medical care evolving to true health care involving population-based principles. Dr Chuang's experience spans the entire health care continuum. Dr Chuang's background in applied healthcare informatics, especially in the areas of controlled medical terminology (CMT), knowledge representation, clinical decision support (CDS) and analytics, are key to clinical process optimization on a health information technology (HIT) platform.
