Hospitals generate dense streams of timestamped operational events, including orders, transfers, staff actions, queue changes, and system interactions. These events describe how care actually unfolds, yet much of their value remains unused because they are rarely labeled for prediction tasks. Existing operational predictive models often depend on task-specific labels, handcrafted features, and local workflow assumptions. This limits their ability to scale across hospitals, departments, and evolving operational conditions. This manuscript designs a self-supervised representation learning model that pre-trains on diverse healthcare operations event streams. The goal is to learn a generalizable embedding of hospital operational state that can be adapted to multiple downstream prediction tasks. The proposed model uses a transformer-based architecture trained with masked event modeling and temporal contrastive learning. Timestamped orders, transfers, staff actions, queue transitions, system interaction logs, and unit-level workflow signals are represented as time-aware event sequences, and the pre-trained backbone is later fine-tuned for specific operational tasks. Conceptually, the model could learn semantic and temporal regularities of hospital workflow, such as common discharge sequences, clustered STAT order activity, and operational precursors to bottlenecks. These representations would be expected to support downstream tasks such as delay forecasting, anomaly detection, and resource demand estimation when labeled data are limited. Self-supervised learning could unlock the latent value of healthcare operations logs by creating reusable representations of hospital workflow. Such a model could become a foundation for operational analytics, enabling faster and more adaptable development of predictive tools.
