  The advent of foundation models (FMs) as an emerging suite of AI techniques
has struck a wave of opportunities in computational healthcare. The interactive
nature of these models, guided by pre-training data and human instructions, has
ignited a data-centric AI paradigm that emphasizes better data
characterization, quality, and scale. In healthcare AI, obtaining and
processing high-quality clinical data records has been a longstanding
challenge, ranging from data quantity, annotation, patient privacy, and ethics.
In this survey, we investigate a wide range of data-centric approaches in the
FM era (from model pre-training to inference) towards improving the healthcare
workflow. We discuss key perspectives in AI security, assessment, and alignment
with human values. Finally, we offer a promising outlook of FM-based analytics
to enhance the performance of patient outcome and clinical workflow in the
evolving landscape of healthcare and medicine. We provide an up-to-date list of
healthcare-related foundation models and datasets at
