Did You Check on the Patient? Building a Protocol Compliance Engine

Summary

Cloudphysician developed a Protocol Compliance Engine to address preventable ICU deaths caused by inconsistent execution of clinical best practices across its tele-ICU network. This system monitors over 500 patients in more than 200 ICUs in real-time, ensuring adherence to protocols like the sepsis bundle. The engine defines protocols using declarative YAML configuration files, which specify patient criteria, individual components (e.g., medication orders, conditional logic), and weighted scoring. Its ProtocolAuditEngine processes these YAML files against incoming patient telemetry, calculating a compliance score categorized as Excellent (>=0.90), Good (>=0.75), Fair (>=0.50), or Poor. The architecture also tracks the FASTHUGSBID checklist every 12 hours per patient, driving real-time dashboards, gamified leaderboards, and automated chat alerts for compliance below 75%. Future enhancements include self-serve UIs and NLP for complex rule handling.

Key takeaway

For MLOps Engineers or Healthcare IT Architects building real-time compliance systems, defining protocols as declarative YAML schemas is crucial. This approach decouples complex clinical logic from the core engine, enhancing maintainability and scalability. You should prioritize clear clinical-to-code translation and consider custom evaluators for nuanced rules. This strategy enables robust, auditable systems that drive operational improvements and patient safety.

Key insights

Declarative schemas and a generic engine enable real-time clinical protocol compliance at scale.

Principles

• Consistent execution of best practices prevents most ICU deaths.
• Clinical protocols are dynamic, context-dependent, and nuanced.
• Documentation compliance reliably proxies clinical actions.

Method

Define clinical protocols as declarative YAML schemas with patient criteria, weighted components, and conditional logic. A generic audit engine ingests these, evaluates against real-time telemetry, and computes a weighted compliance score.

In practice

• Define complex workflows using declarative YAML configurations.
• Implement custom Python evaluators for nuanced clinical rules.
• Gamify compliance metrics to boost team adoption.

Topics

• Clinical Protocol Compliance
• Tele-ICU Systems
• Declarative Schemas
