PURPOSE
Clarify our thinking about innovation and research
Share experience with an approach to innovation developed in Boston and Toronto
Research Ethics CaseDr. Edge is studying the Zeus robotic system for
minimally invasive cardiac surgery. It minimizes the need for residents to hold the heart, position the telescope, apply suction, or irrigate the field.
He will report his experience at the upcoming AATS meeting. He needs 6 more patients to round out his series to 100 cases. The safety committee has asked for increased surveillance because of concerns about side effects: 4 aortic dissections, 2 strokes, 2 ischemic limbs, 1 amputation.
Grandmother wants a minimally invasive CABG. She does not quite fit eligibility criteria – at 72 she is 2 years over the protocol age limit. She wants to wait a few weeks before the surgery.
You are a Resident on the Research Ethics Board. What advice would you give Dr Edge?
Questions
1. Should Grandmother be entered into the study if she is willing to have the surgery now?
2. Can we use a patient’s consent to treatment to enter her into a study?
Why not use a patient’s consent to treatment to enter her into a study?
• “Tyranny of the protocol”mandated techniquesrequired follow-up tests
• Conflicting intereststhe investigatorthe sponsorthe institution
• Confidentiality may be breached through data collection & storage
World Medical AssociationDeclaration of Helsinki
• The well-being of the subject should take precedence over the interests of science.
• Each experimental procedure should be formulated in a protocol.
• Consent should be fully informed about the experiment.
• Subjects have a right to withdraw.

World Medical AssociationDeclaration of Helsinki
Where proven methods do not exist or have been ineffective, the physician, with informed consent from the patient, must be free to use unproven or new measures, if (they) offer hope of saving life, re-establishing health or alleviating suffering.
Practice: “If it might help, give it a try”
Research: “Don’t study it without approval of a research ethics committee”
Helsinki Innovation Paradox
Innovation: “… in the borderland…”
Questions
3. Is it morally acceptable for physicians to use patients from their practice as subjects in research?
4. Is it morally acceptable to enter your patients in a randomized trial when you strongly believe that one treatment is superior to the other?
Clinical equipoise:
Uncertainty in the informed medical community about which is the best test or treatment .
Benjamin Freedman
Distinguishing Innovation from Research
Innovation• modify accepted procedures in incremental steps• change accepted practice based on observation /
reasoning
Research• systematic investigation to yield generalizable data• test a hypothesis
“Family resemblance” based on experimental nature.
An experiment is not necessarily research.
Experiment:
A procedure tentatively adopted without certainty that it will achieve its purpose.
Experimental: tentative, provisional… based on (often incomplete) experiment
Canadian Oxford Dictionary 1998
Quality Improvement
Surgeons have a moral obligation to improve the quality and outcomes of their interventions.
Studying the quality and outcomes of treatment is not identical with formal research.

Innovation
Innovation Case
Dr. Keshavjee has a donor lung that proves to be too large for the thorax of the recipient. He considers performing a volume reduction operation on the recipient’s contralateral residual lung to make room for the transplant.
This has never been done before. You are the resident. Is this innovation ethically justified?
If it works, should this be adopted as standard treatment?
The Bright Side of Innovation
Anesthesia
Appendectomy
Transplantation
Heart surgery
The Dark Side of Innovation
Internal Mammary Ligation
Radical Mastectomy
1968 Heart Transplant Epidemic
Living Donor Liver Transplant
The Expensive Side $1.2 M
Should the surgeon decide when it’s
okay to try something new?
“Meditation before surgery”
by Joseph Wilder, MD
Surgical Peers and Trainees
Shouldn’t there be some oversight?
OR Community Oversight
Surgical Oversight Paradigm• OR community oversight
• Operating schedule published*
• M & M conferences
• Audit and quality improvement reports
• Professional and public reporting
• SIC responsible to public
• Credentialing and privileging processes
When Should Innovation Require Additional Oversight ?
Procedure carries significant increase in risk above alternative approaches
Procedure is so novel that risks and benefits are unknown
Procedure affects the allocation of resources
Kornetsky & McKneally
Heung Kim’s STEP
How We Do It at UHN & HSC
1. Surgeon initiates “Enabling Innovation Letter” to SIC• Expected benefits, risks and costs• Cosigned by two informed colleagues
2. Adds “Columbus Clause” to standard consent form*
“I understand that this treatment is new to this hospital. I will be one of the first [#] patients to receive it here. I have been offered the standard treatment. My doctors and nurses are working to find the best way to perform the new treatment and learn which patients will benefit most from it.”
The Columbus Clause
I told them I wouldn’t sail off the edge!
How We Do It at UHN & HSC
3. If needed, SIC consults Innovation Task Force (nursing, anesthesia, engineering, ethics)
4. SIC shows letter and form to Chair of REB who accepts, or advises full review
5. Innovator reports outcome in first [#] patients to SIC Help from hospital data managers Cost estimates from OR manager
6. SIC reviews projects annually with REB chair
7. Formal research initiated when appropriate
Toronto Examples: UHN - HSC
• Phototherapy of esophageal cancer
• Retinal vein decompression
• Laparoscopic prostatectomy
• Minimal access pediatric surgery– Pectus repair– Hirschprung’s disease
Some Patients are Heroes
Some Rely Only on Trust
“Professor Barnard, I want to go through with it now more than ever - not only for my sake but for you and your team…” Philip Blaiberg
From: Jay Katz, “The Silent World of Doctor and Patient”
On the day after the death of Louis Washkansky, the first heart transplant recipient …
The Case revisited
Grandmother should not be pressured to accept an earlier surgery date to meet the conflicting scientific goal of 100 patients in time for the AATS meeting.
She and other patients can be offered the innovative treatment off protocol – on a preapproved compassionate basis,
or as part of a less restrictive, exploratory plan to evaluate the innovation.
