1 University Hospital Brussels
1 december 2005 Project “ABRUMET” Proposal for a Regional Medical Network R. Van de Velde University Hospital Brussels AZ VUB Vrije Universiteit Brussel

2 About Abrumet : Organisation for Telemedicine in Brussels
Members GP  FAMGB, BHAK Hospitals  AZ-VUB, CHIREC, Clinique de l’Europe, Erasme, C. de Paepe, Sanatia, Saint Jean, Saint Luc  IRIS (hospitals – CTO) Objectives To foster availability, accessibility and portability of patient records by means of Health Information Networks (HIN) Collaboration: ability to share medical information between authorized HC workers To stimulate confidence of general Practitioners and increased investment in CPR Bilingual To encourage patients to take a more important role in managing their health records .

3 Why? Why? Why? What? How? When?

4 What if a physician requests a patient record?
May I please have the Patient Record?

5 x Hospitals : Do not share information
The Answer is Yes, but … x Do not share information H1 H2 H3 Hospitals : Have distinct security approaches AZ-VUB AMIS UZL LISA . . . Lock up data in proprietary formats Perceive competition

6 Even when information is electronically available
The Answer is Yes, but … Even when information is electronically available in an electronic medical record in a pharmacy system in a digital radiology system …. The patient is generally given at personal inconvenience, a hard copy No “export” function available !

7 What if we gave GPs a tool to request their records electronically?
x x H1 H2 H3 Abrumet First Phase:

8 Finding Records: Manual Approach
Laboratory Results Specialist Record Hospital Record Records Sent The challenge: Finding and accessing easily documents from other care providers in the community. Clinical Encounter Clinical IT System

9 Finding Records: The Abrumet Way
Laboratory Results Specialist Record Hospital Record 3-Records Returned Temporary Aggregate Patient History 3-Patient data presented to Physician Clinical Encounter Clinical IT System Index of patients records (Document-level) 2-Reference to Records for Inquiry 1-Patient Authorized Inquiry

10 What? Why? What? How? When? What?

11 Publication & Visualisation Documents
Services Publication & Visualisation Documents Distributed Location – Written Consent Bi-directional Data Keepers Messaging (Push/Pull Model) Location messages : secured centrally Specific system (uniform access method) SMS : “Event-driven” For Critical Messages (Panic Lab Values, Emergency Adm,…)

12 The Patient “Longitudinal” Record
General Practitioner Clinical B Other Specialized Care Clinical A Typically, a patient goes through a sequence of encounters in different Care Settings

13 Requirements (1/2) Foundation for a federated Health IT Infrastructure: Focussing on a shared Electronic Health Record, in a community, region Distributed: A “federated” system composed of distinct, distributed, disparate, decentralized systems defined as “data keepers”. Each Health Care organization “publishes” clinical information for authorized users. Information that remains in the original location of creation. Document Centric: Published clinical data is organized into “clinical documents” based on agreed standard document types Sharing of documents between General Practioners, clinics, pharmacists, … with different medical IT systems Consistent graphical user interface: Care providers are offered means to query and retrieve clinical documents of interest in the same consistent way independent of the source of information

14 The Master (Community) Patient Index
14355 L-716 M Master Patient Index Document Registry Patient Registry Document Repository Laboratory Clinical B Abrumet Portal Clinical A Submission of Patient & Doc References Retrieval of selected Documents

15 Requirements (2/2) Cross-Enterprise: A Master Patient (Community) Index provides an index for published information to authorized Healthcare Patient maintains control and can grant access to selected portions of his/her medical record (ACL) for authorized users specific to their role Physicians can be granted access to the record or portions of it to read or write. Should the patient choose they may be locked out at a future time. Collaboration is optimised Standardized Queries: Are based on Web Services and KMehr standard Easy access based on Single Sign On (SSON) without installation of specific software at the user site with the same tokens/cards Interconnectivity: The system enables links to other related networks such as CareNet, Be Health, Social Security, RIZIN-INAMI, ...
