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
informed CONsent for clinical record and
Sample use in research (iCONS)

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.
SNAPSHOT PERMISSION ONTOLOGY
A <subject> has <permission> or <obligation> to
perform an <operation> over <biological
specimens> or <medical records> under
constraints
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

compliance
with subject’s
permissions
and HIPAA
constraints?
1) Are the
resources
available?
Can I have
access to blood
samples and
diagnostic data
from patients with
breast cancer?
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
User U has IC permission to access cancer treatment history
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
