• Definitions
• IRB review
• Informed consent
• Confidentiality + HIPAA
• Human material
• Chart reviews
Definition of ResearchDefinition of Research
• Research means a systematic investigation, including research development, testing and evaluation, designed to develop or contribute to generalizable knowledge
Publication plans irrelevant
Definition of SubjectDefinition of Subject
• Human subject means a living individual about whom an investigator (whether professional or student) conducting research obtains:
(1) data through intervention or interaction with the individual
(2) identifiable private information
Subjects involved?Subjects involved?
Interaction due to research?
Yes No
Identifiable info?
Subjects involved
No subjects
Human Subjects Human Subjects ResearchResearch
• IRB approvalfull boardexpedited
• Informed consentfull written consentaltered or waived consent
Research Exempt from Research Exempt from ApprovalApproval
• Educational testing
• Some surveys
• Some studies of existing data or specimens
• Study of public service programs
• Taste and food quality evaluationIRB, not investigator,
decides
What does an IRB do?What does an IRB do?
• Review, approve, require modifications or disapprove research
• Review informed consent
• Conduct continuing review
• Have authority to observe consent process and research
45 CFR 46
Criteria for approvalCriteria for approval• Risks to subjects are minimized• Risks to subjects are reasonable relative to benefits
• Selection of subjects is equitable• Provisions made for data, safety monitoring • Provisions made to protect confidentiality• Safeguards in place for vulnerable subjects• Informed consent will be sought, documented
Risks minimizedRisks minimized
• Background/importance of problem
• Study design issuesGood endpointsJustifiable sample sizeAppropriate biologic correlates
Leverage clinical procedures
• Less risky way to get answer?
Risk-benefit ratio Risk-benefit ratio favorablefavorable
• How much risk?To individualTo family?To society?
• How much benefit?To individual To society
• Adequate data analysis planProtocol endpointsSafety monitoring
Informed consentInformed consent
• Tell people why you’re doing this and what’s going to happen to them!
• Risks (not underestimated)
• Benefits (not oversold)
• 7th grade language
Informed consentInformed consent
• What the research is
• Procedures involved
• Risks, benefits
• Treatment/compensation for injury
• Alternatives
• Right to withdraw
• Confidentiality
• Contacts for questions
Basic elements
Informed consentInformed consent
• Unforeseeable risks
• Circumstances for termination of participation
• Additional costs
• Procedures for withdrawal
• Notification of new findings that might affect willingness to participate
• Approximate number of subjects
Additional elements
ConfidentialityConfidentiality• Consider subject privacy
Where you’ll talkHow intrusive?
• Safeguard confidentiality of dataLocked doorsPassword protected files
• Consider risks if confidentiality breachedGenetic info- parentage, insurancePsychological harmJob status
• Who gets access, what circumstances• What happens to samples
HIPAAHIPAA
• Privacy rule
• “Limiting the ways that health plans, pharmacies, hospitals and other covered entities can use patients’ personal medical information.”
• Authorization to use PHI usually part of consent form
• Applies in some settings where research regs don’t
Waiver of Consent?Waiver of Consent?
Special types of Special types of researchresearch
• Tissue samples onlyTissue banks complex
• DatabasesDo not need IRB approval for operational use
DO need IRB approval for research on data
• Chart reviewsNeed IRB approval (HIPAA)
Consult with IRB
Tissue BanksTissue Banks
• Critical research resourceGenomicsProteomicsFuturomics
• Samples held indefinitely
• Future uses unpredictable
• Sample used in other studies
• Clinical correlation valuable

Types of sampleTypes of sample
• AnonymousNo links exist anywhere
• CodedA link existsTissue recipient does not have key
Repository does
• IdentifiedTissue recipient can connect tissue to donor
Defined by link to donor
Kinds of IRB reviewKinds of IRB review
• Anonymous samplesCan be exempt from IRB review
• Coded or identified samplesIRB review requiredExpedited review may apply if minimal risk
• Samples all from decedentsExempt from IRB review (not human subjects)
Still need HIPAA review
Determined by type of sample
Consent considerationsConsent considerations
• Informed consent required• Special considerations
Subject contact:What PHI being collected?Duration of follow-upRecontact re: future studies?
Sample use:This study only?Any study related to condition?Unspecified future studies?
Prospective sample acquisition
Waiver of consent?Waiver of consent?• Only if minimal risk
Confidentiality well protectedNo release of PHIRights of subject not compromisedAdequate plan to reveal important findings
• AND impracticable to get consent
Most applicable to previously banked specimens
Few good reasons if prospective collection
Tissue Collection Tissue Collection Exempt?Exempt?
Chart ReviewsChart Reviews
• IRB approvalusually expeditable
• Informed consent?- Not (usually) if retrospective review*Justify waiver of consent and authorization in IRB application
- Yes if prospective data collection
• “Dear colleague” letterpassive approval from other MDs
DatabasesDatabases
• If for TPO (or education), no IRB or HIPAA issue
• If collecting PHI but not for research, need authorization (or waiver)
• If collecting PHI for research, need informed consent (or waiver)
QI/QAQI/QA• Effectiveness of programs
• Improvements in health care delivery in particular settings
• Not usually research if intended for internal program evaluation without generalization
• Difficulty is in deciding when insight becomes “generalizable”
