Prototype Overview
Hospital Data Integration & Multi-Level Cost Allocation
A vendor-neutral prototype showing how clinical, financial, HR, supply-chain, asset, and medical-technology data can be standardised into a multi-level cost-allocation and management-reporting model.
Prototype · Synthetic Data Only
This is a prototype. All data is produced by a deterministic, seeded data-generation algorithm. No real patient, hospital, vendor, or commercial information is involved.
Built on published methodology
Every component implements a public-domain method from the academic literature or international healthcare-IT standards. Architecture follows standard hospital-IT layering (HIS / EMR / ERP / ancillary systems) per HIMSS EMRAM and HL7 FHIR conventions. No proprietary or organisation-specific methodology is reproduced — implementations are written from scratch against open sources.
- Multi-level cost allocation— Kaplan, R.S. & Porter, M.E. (2011), “How to Solve the Cost Crisis in Health Care”, Harvard Business Review; Cooper & Kaplan (1991) on Activity-Based Costing; Horngren et al., Cost Accounting (textbook step-down allocation).
- Disease-group / case-mix costing — Fetter, R.B. et al. (1980), “Case Mix Definition by Diagnosis-Related Groups”, Medical Care; Medicare DRG system (1983); WHO ICD framework (concept only — codes used in this prototype are synthetic).
- Multi-source data integration — HL7 FHIR R4 (industry standard); IHE (Integrating the Healthcare Enterprise) profiles; HIMSS EMRAM maturity model.
- Mapping governance & data quality— Wang & Strong (1996), “Beyond Accuracy: What Data Quality Means to Data Consumers”, JMIS; DAMA-DMBOK; ISO/IEC 25012 data quality model.
Core Idea
Translate multi-source hospital data into a single governed model, then run multi-level cost allocation to expose true full cost by department and case.
What It Shows
8 source systems → standardised detail layer → allocation engine → executive overview, department drilldown, case cost, and mapping governance.
Allocation Logic
Direct cost → admin pool → auxiliary pool → medical-tech pool → final full cost on clinical departments, driven by headcount, area, bed-days, lab/imaging volume, etc.
