Challenges
•
•
•
•
Extremely large Datasets
Incompatible Data formats and languages
Human Safety
Collaboration Vs. Security
Large Datasets
• GenBank contains over 15 million sequence
records
• Many Bioinformatics companies have 200+
terabyte storage for proprietary information
• Most systems incorporate proprietary
information with multiple sources of public
information
The Data

Incompatible Data

•
Mesh ( medical subject heading )
UMLS ( unified medical language system )
RCS ( read classification system )
SNOMED ( systemized nomenclature of human and
veterinary medicine )
ICD-ID ( international classification of diseases )
CPT ( current procedural terminology )
GEML ( gene expression markup language )
MAML ( microarray markup language )
FASTA ( popular sequence data format )
MmCIF( popular format for describing 3d structures )
and many more!!! ( especially proprietary ones )
Human Safety
• Medical devices are LIFE CRITICAL
• About 5000 compounds evaluated by
pharmaceutical companies yearly, 5 make it
to human trials, 1 makes it to market
– 4995 were thrown out right away
– 4 were thrown out after they were tried on people
– One of the major reasons is safety
Collaboration and Security
• There WILL be attacks
– BioMedical information can be worth a lot
– There are active groups that appose certain
BioMedical research areas
• There are now laws regarding medical
information’s security and privacy
– Security breaches can turn into lawsuits now
• Collaboration is very high in BioMed
Aspects of BioMedical Computing
• Process Control
– Medical equipment
– Laboratory automation
• Archiving
– Public and Private Databases
– Data Dictionary
– Backups
• Numerical Processing
– Simulations
– Data mining
– Visualization
• Communications
– Collaborative software
– Software that facilitates collaboration
Aspects of BioMedical Computing
This one
could be
collaborative
Aspects of BioMedical Computing
• The four aspects are usually combined in
one way or another to make one BioMedical
tool or system
– Chimera combines collaboration and modeling
– Entrez combines archiving and numerical
analysis
Importance of Standards
• Capture “best practices”
• Reuse of what works helps prevent mistakes from
being repeated and helped success be duplicated
• Help increase safety, and are often required in life
critical systems
• Can be a helpful marketing tool, who wants to by a
noncompliant produce?
• Maintenance and re-engineering is easier if
program was designed and coded using
documented standards
Standards in Process Control
• IEEE 1073 family of standards
– Point of care medical device communications standards
– Specify formats, speeds, and communication protocols
for medical devices
– Goal is standardized plug and play medical equipment
– Covers devices such as vital signs monitors, defibulators,
weighing scales, and much much more
– Aims to increase safety by allowing devices to interact,
increasing continuity of care
– Are a work in progress
Standards in Archiving
• HIPAA
– Health insurance portability and accountability
act
– It’s not just another pretty acronym, it’s the law
– HIPAA covers
• Health plans, Health clearinghouses, and healthcare
providers
• Entities with business relations with a covered entity
– Contractors, consultants, and service providers
– Paid researchers
• Anonymous information is not covered
Standards in Archiving
• HIPAA
– Requires you to protect stored data’s
• Confidentiality
• Integrity
• Availability
Standards in Archiving
• HIPAA
– HIPAA requires that standards are in place, but is
open ended
– The Process HIPAA recommends for
implementing security standards is
• Assess risks and vulnerabilities to information
• Develop, implement and maintain security measures
appropriate to your particular needs
• Document these measures in the form of standards
Standards in Archiving
• HIPAA
– HIPAA does have some more specific requirements with
regard to security of archiving
•
•
•
•
•
•
The standards shall include access control
The standards shall include some form of crypto
The standards shall include a data backup plan
The standards shall include a disaster recovery plan
The standards shall include and emergency operation plan
The standards shall be periodically reviewed and tested, and the
timetable for this shall be in the standards
Standards in Archiving
• HIPAA
– HIPAA standards are mostly operating procedure
standards, but can still impact software design
considerably
• When designing software for medical entities
• When maintaining and re-engineering systems that
are not compliant
• When making BioMedical software that must use data
owned by covered entity
Standards in Archiving
• Data Dictionary
– BioMedical programs must often access numerous public
databases
• GenBank ( for gene sequences )
• SwisProt ( for protein sequences )
• PDB ( for 3d protein structures )
– Even databases that contain the same type of info often
have different data formats
– Companies and programs need to tie these different
databases with different formats into one consistent “data
mart” for utilization
– This is achieved with a standard “Data Dictionary”
Standards in Archiving
• Data Dictionary
– A Data Dictionary must contain one standard
format for all types of information to be
integrated
– A Data Dictionary must contain standards on
how to convert other formats that will be
accessed into the standard format

Standards in Numerical
Processing
• Data Mining makes use of the Data
Dictionary
• Visualization makes use of standard “look
and feel” that users are accustomed to
• OpenGL is the de facto standard for
implementing 3D graphics in BioMedical
computing
Standards in Communications
• HIPAA
– HIPAA requires data transfer systems to have standards
that address the following
•
•
•
•
•
•
•
•
Data Integrity
Message Authentication
Entity authentication
Access Controls
Encryption
Alarms
Audit trails
Event reporting
Conclusions
• BioMedical Computing faces many
challenges and risks
• Large and Incompatible data sets
• Human safety
• Collaboration vs. security
• These challenges and risks are met with the
use of standards
