On December 8, 1989, Claude Lenfant, then Director of the National Heart, Lung, and
Blood Institute (NHLBI) sent a memo to his Division Directors instructing them to
inform contractors and grantees about the Institute’s data sharing policy. He wrote,
“It is the policy of the NHLBI to make available detailed data from collaborative
clinical trials, epidemiological studies, and other large-scale studies … with adequate
protection of the confidentiality and privacy of research subjects.”

Dr Lenfant wanted assurance that the federal government’s investments in research
would achieve maximal potential by enabling researchers who were not direct beneficiaries
of those investments to analyze shared data and in turn to share their findings, through
publication, with the community. Indeed, one of us (MSL), as an early-career investigator,
took advantage of NHLBI’s policy of sharing to publish independent analyses based
on data generated by an NHLBI-funded investigation.

And the importance of sharing has been recently reaffirmed as a critically important
measure of the value of biomedical research.

Since 1989, we have come a long way. At the end of the punched card era, the NHLBI
Framingham Heart Study converted massive tabulations of collected variables into 38
monographs that were made freely available for outside researchers, many lacking computing
resources.
4
As technology advanced, punched cards moved to reel-to-reel tapes, to big floppy discs,
to smaller ones, to CDs, to secure FTP, enabling data transfer with increasing content
and efficiency. Data sharing processes eventually moved from ad hoc requests to well
defined and well-documented web-based systems including BioLINCC
5
and dbGaP.
6
Data sharing has also evolved from collaboration of a few studies
7
to massive collaborations that have included more than 50 studies.
8
Data sharing offered great opportunities for advancing research, but as Dr Lenfant
intimated, also presented challenges that went beyond exploiting advances in computing
technology. As responsible overseers of federally funded research, we needed to be
certain that participants were aware that their data could be shared and that they
provided clear consent for sharing. The consent form for Framingham Heart Study participants
in 1950 – it was only one page long – looks very different from the one of today.
9
Participant consent now requires permission as to who should or should not receive
their data, whether restricted by content or for-profit companies, and whether there
are sensitive data that should not be shared with anyone beyond the first-line researchers.
In the current issue of Circulation, the American Heart Association (AHA) describes
its broad and comprehensive initiative, the Cardiovascular Genome-Phenome Study (CV-GPS).
10
The AHA recognizes the extensive returns of NHLBI’s decades-long investments in cardiovascular
population-based research, which have produced massive quantities of high-quality
resources and data to be shared with the research community. The AHA also recognizes
a continued need to enable, through funding, innovative phenotyping to expand on what’s
already available. Therefore the AHA has initiated a funding process to conduct innovative
research that leverages existing studies,
11,12
including the Framingham Heart Study, the Jackson Heart Study, and other mature population-based
cohort studies. They will be funding Pathway Grants of $250 000 per year for 2 years
(8 in 2014–2015) and Challenge Grants $500 000 per year for 2 years (1 in 2014–2015).
In the CV-GPS funding announcement the AHA states that this innovative research will
“point the way toward better-targeted, safer, and more effective treatments, based
on a deeper understanding of patient’s characteristics.”
11
The AHA’s CV-GPS initiative fits the model of capitalizing on existing studies through
funding creative investigators armed with new hypotheses, skills, perspectives, and
technologies. The initiative builds on a longstanding NIH tradition of funding “ancillary
studies,” an important kind of “reinvestment” in NHLBI’s work. We at NHLBI see ancillary
study reinvestments as a valid metric of the value of our prior investments. We are
particularly pleased when funders outside of NIH, including companies and nonprofit
foundations like the AHA, choose to reinvest, as we see this as evidence that our
investments are deemed so worthwhile that others wish to help us share them with their
grantees. Reinvestment is a kind of sharing: through the CV-GPS the AHA is choosing
to dedicate considerable funds to share NHLBI-generated resources and data with outstanding
researchers who will now be able to conduct outstanding science. And this kind of
reinvestment sharing enabled by professional societies is critically important given
the unprecedented fiscal challenges we now face.
13,14
Just like data sharing, reinvestment sharing presents opportunities and challenges.
The CV-GPS projects just awarded by AHA have promise to enhance public health by studying
a diversity of interesting problems, from epigenetic determinants of left ventricular
structure to correlates of early-onset stroke to integrative genomics of gene-diet
interactions related to vascular disease. But the initiative also recognizes that
resources and data coming from existing studies live within a framework of informed
consent. Just as we at NHLBI are pleased by AHA’s decision to reinvest in and enable
sharing of our resources, we are also pleased that the instructions to applicants
noted that “investigators will still be required to adhere to the practices established
by the parent studies of those databases to protect the quality and confidentiality
of the data and samples.”
11
There is a phrase often used in a military context that is appropriate here, “to serve
and protect.” We offer a modified version – “to share and protect.” The NHLBI is dedicated
to serving the research community, to providing the best possible data and the best
possible access while protecting the almost sacred connection between the original
research teams and participants established through their human interactions and bound
by their consent. By reinvesting in NHLBI’s resources and data, by enabling sharing
of these with outstanding scientists, and by assuring that maximal protections remain
in place, the AHA is becoming a valued participant in our shared goal of a healthier
world.
