The Geisinger CDS Compendium — a nine-chapter retrospective on turning a transactional EHR into a real-time, value-driven care-transformation engine. The methods Acumenus productizes today, proven where they were built.
The Narrative
Each chapter is a program that turned raw clinical data into intelligence and put it back into the workflow — where it changed what happened to a patient.
The platform, the data-quality discipline, and the whole portfolio in one narrative.
Stage the diagnosis, identify the population, hard-wire the follow-through.
Inpatient glucose off the real-time HL7 lane, triaged daily by pharmacy.
Vital deterioration scored continuously and escalated before the code.
No abnormal result falls through — every open loop documented to resolution.
A progress note that assembles itself and codes as you write the plan.
Care that happens before the visit — protocol orders and pre-visit closure.
Make the generic diagnosis uncomfortable — taxonomy applied to two conditions.
Disciplined doubt: the anomaly gallery, the dimensional model, the rules engine.
From Proof to Product
Every Acumenus platform traces back to a program in this Compendium — the same discipline, rebuilt as open-source software any health system can run.
The dimensional model, the rules engine, and the 410+ measures of Data Discovery & Platform and the CKD taxonomy — now a unified OMOP outcomes-research platform.
The care-gap engine behind AMP & Auto-Orders and Close the Loop — now standards-native population health with CDS Hooks and FHIR.
The real-time HL7 scoring behind MEWS and Glucometrics — now a hospital operations and deterioration-monitoring platform.
The structured-diagnosis taxonomy and decision discipline of Obesity & Heart Failure — now a molecular tumor board for multidisciplinary cancer care.
Acknowledgments
The methodologies in this Compendium were forged at Geisinger Health System, under leadership that treated care delivery as something to be engineered, not exhorted. I am deeply grateful to the mentors and leaders who built that environment and trained me within it.
Architect of Geisinger's value-based transformation — ProvenCare® and ProvenHealth Navigator® — whose vision for re-engineered care made this work possible.
Built the clinical-innovation and informatics engine in which these systems were designed, deployed, and scaled across the health system.
Led the clinical re-engineering program that closed a quarter-million evidence-based care gaps — the discipline of closing the gaps at the point of care.
“Under their leadership, I learned to turn clinical data into intelligence that changes what happens to a patient. The platforms Acumenus builds today are those methods — proven there, now made real and offered to the broader healthcare community.”

Nine chapters, two of them interactive. The platform beneath it, the data-quality discipline that made it trustworthy, and the program portfolio it powered.
