1 PERMISSION ONTOLOGY FOR INFORMED CONSENT AND HIPAA COMPLIANCE Maria Adela Grando PhD Division Biomedical Informatics, University California San Diego CTSA ONTOLOGY WORKSHOP - Febrary 11st 2013, Orlando-

2 AGENDA State of the art Aims and vision: informed CONsent for clinical record and Sample use in research (iCONS) Permission Ontology Resource Mediator Future work, conclusions

3 STATE OF THE ART Mostly, the research enterprise relies on paper-based Informed Consent documents which contains permissions given by subjects to share specimens and clinical data for future research. It is rare that consent forms are collected electronically. There is potential to use electronic Informed Consents for: providing compliance with subject’s permissions, while maximizing access to resources

4 informed CONsent for clinical record and Sample use in research (iCONS) Electronic IC I authorize U to perform operation O over my data D or sample S under certain constraints C Look-up Registry I can check publications generated from my data and samples Patient I Clinical Data Warehouse Query User U requests Data D and sample S to perform operation O on subjects like I under constraints C User U Research Institution Healthcare Institution Results User U receives data D and sample S in compliance with subject’s permission Home Permission Repository Informed Consent Management System BioSample Repository I share my blood samples with non-profit US researchers I share my blood samples with non-profit US researchers As a Stanford researcher can I get blood samples? As a Stanford researcher can I get blood samples? Resource Mediator Permission Ontology

5 PERMISSION ONTOLOGY For describing permissions obtained from subjects who signed an Informed Consent or HIPAA form, in a uniform, machine-interpretable, implementation-independent way To enable interoperability and sharing of Informed Consent permissions and HIPAA constraints between clinical data warehouses and bio-repositories, independently of their implementation choices.

6 SNAPSHOT PERMISSION ONTOLOGY A has or to perform an over or under constraints

7 RESOURCE MEDIATOR We have built for UCSD Moores Cancer Center Biorepository a Resource Mediator Prototype, for: Providing researchers access to clinical data and biospecimens resulting from the research study “Collection and Banking of Tissue, Blood and Urine for Use in Cancer Research” We have tested the prototype with: de-identified patient cases (700 patients, 2635 medical record entries) 8 randomly chosen (from 33) researchers’ requests for data and samples

8 RESOURCE MEDIATOR GUI

9 RESOURCE MEDIATOR Can I have access to blood samples and diagnostic data from patients with breast cancer? 1) Are the resources available? 2) Is in compliance with subject’s permissions and HIPAA constraints?

10 RESOURCE MEDIATOR We have provided ontology-reasoning for determining compliance with IC permissions and HIPAA constraints: User U request access to patient treatment history User U is denied by HIPAA access to alcohol abuse treatment history User U has IC permission to access cancer treatment history

11 CONCLUSIONS There is a need for: a standard to maximize the availability of resources while providing compliance with subject’s Informed Consent permissions and HIPAA constraints We propose: an Electronic Informed Consent Management System, a Permission Ontology, a Resource Mediator based on an hybrid approach combining the proposed Permission Ontology and a XACML-policy engine

12 FUTURE WORK Query User U requests Data D and sample S to perform Operation O on subjects like I under constraints C User U Research Institution Results User U receives data D and sample S in compliance with subject’s Institution A BioSample Repository Resource Mediator Clinical Data Warehouse Permission Repository IC Form + HIPAA IC Form + HIPAA Institution B BioSample Repository Clinical Data Warehouse Permission Repository IC Form + HIPAA IC Form + HIPAA Permission Ontology

13 ACKNOWLEDGEMENT 5 year NIH-founded National Center for Biomedical Computing, started in September 2010.
