Integrated Data Management System

for the Biorepository

Biorepository

Part of the Mission and Goals Statement

… the limited availability of carefully collected andcontrolled, high-quality human biospecimens annotated

with essential clinical data and properly consented forbroad investigational use … is repeatedly identified by

the scientific community as a leading obstacle toprogress in post-genomics cancer research …

Standard Process

Goal

• Combine different biobanks– Hollings Cancer Center– MUSC Brain Bank– SCTR biobank

• Link different data sets on one screen

For Researchers

Goal

• Add additional knowledge relating to their samples without having to go to many different systems.

For Biorepository Personnel

User Interface Capabilities

• Filter by ICD-9 codes – diagnostic descriptions• Filter by demographics– Age– Sex– Race

• Ability to de-identify data or eliminate entirely• Maintain an audit trail of samples reviewed• Add to shopping cart or wish list• Simple to use

Admin Slide

Background

• Campus wide use of TissueMetrix using Oracle• Clinical Data Warehouse using Sybase IQ• Cancer Registry’s IMPAC system using MS SQL • Cerner CoPathPlus streaming HL7 messages• PenRad for mammography informatics• Lucene.Net indexing ICD-9 codes• Excel spreadsheets

Combines data from multiple data sources

Technology Details

• Portal uses DNN as foundation• Authentication using LDAP• ICD-9 searches are created using Lucene.net • User Interface uses HTML5, JavaScript, jQuery • Web Services are written in JSON• MS SQL is used for middle tier• 128 bit Encrypted values change every 3 minutes

Balancing Act

Biorepository Data

• Export data nightly to MS SQL database Data Warehouse

• Data is transformed and cleansed so it has consistent meaning.

• May involve restructuring, redefining, filtering, combining, recalculating and summarizing data fields

Security

• 128 bit Encrypted value changes every 3 minutes and is included in the Header of every browser request

• MRN is passed encrypted with key that changes every 3 minutes

• Values are checked on the Web Server to be within accepted values before sending to the Database Server

Summary

• Provides researchers with a simplified view of specimens in inventory

• Users do not require direct access to the database

• Provides for electronic messaging when further interest in specimens is identified

• Identifies availability of specimens for grant proposals
