The NIH Budget and the Future of Biomedical Research
http://www.100md.com 《新英格兰医药杂志》
     Federal funding for biomedical research in the United States has fueled discoveries that have advanced our understanding of human disease, led to novel and effective diagnostic tools and therapies, and made our research enterprise an international paragon. Although it was not the original intent, this investment, through the National Institutes of Health (NIH), has also become an essential source of support for academic medical centers, providing funds for faculty and staff salaries, operational expenses, and even capital improvements related to research that can no longer be supported by clinical income. Until approximately 20 years ago, clinical income often subsidized research, but managed care, increased scrutiny and efficiency in the management of clinical expenses, and reductions in federal support for teaching hospitals have rendered clinical margins insufficient to support the research mission. Although some may see institution building as an inappropriate use of NIH funds, a consistent, productive biomedical research enterprise requires a solid infrastructure.

    Ensuring durable federal support for such research has not, however, been without tribulations. As with all line items in the federal budget, NIH funding is subject to the vicissitudes of the political process, and intermittent periods of growth have been followed by periods of decline (see graph). Some argue that funding cycles refresh the research enterprise, eliminating through competition investigators whose work is not of the highest quality. Though not as sanguine about their purposes or consequences, the academic medical community has accepted these cycles and works to find ways to dampen the effects of downturns on research programs and institutional stability.

    Annualized Growth of the NIH Budget, 1971 to 2005.

    The growth rates shown have been adjusted for inflation.

    We have recently entered another period of stagnant funding for the NIH. Having doubled between 1998 and 2003, the NIH budget is expected to be $28.6 billion for fiscal year 2007, a 0.1 percent decrease from last year,1 or a 3.8 percent decrease after adjustment for inflation — the first true budgeted reduction in NIH support since 1970. Whereas national defense spending has reached approximately $1,600 per capita, federal spending for biomedical research now amounts to about $97 per capita — a rather modest investment in "advancing the health, safety, and well-being of our people."1 This downturn is more severe than any we have faced previously, since it comes on the heels of the doubling of the budget and threatens to erode the benefits of that investment. It takes many years for institutions to develop investigators skilled in modern research techniques and to build the costly, complicated infrastructure necessary for biomedical research. Rebuilding the investigator pool and the infrastructure after a downturn is expensive and time-consuming and weakens the benefits of prior funding. This situation is unlikely to improve anytime soon: the resources required for the war in Iraq and for hurricane relief, along with the erosion of the tax base by the current administration's fiscal policies, are expected to have long-term, far-reaching effects.

    Most institutes within the NIH have quickly adopted policy changes to minimize the adverse consequences, including reducing the maximum grant term from five years to four years, eliminating cost-of-living increases, and capping the amounts of awards. These changes have important effects on currently funded research and the infrastructure that it requires. Moreover, the future of biomedical research is also affected: NIH training grants represent a major source of support for postdoctoral and clinical fellows during their research experiences, and budget limitations affect not only available training slots but also the training climate. As it becomes increasingly difficult for established investigators to renew their grants, their frustration is transmitted to trainees, who increasingly opt for alternative career paths, shrinking the pipeline of future investigators.

    Meanwhile, for more than 10 years, the pharmaceutical industry has been investing larger amounts in research and development than the federal government — $51.3 billion in fiscal year 2005,2 for instance, or 78 percent more than NIH funding that year. Fiscal conservatives may view this industry investment as an appropriate, market-driven solution that should suffice and that does not justify additional government funding for biomedical research. However, the lion's share of industry funds is applied to drug development, especially clinical trials, rather than to fundamental research and is targeted to applications that are first and foremost of value to the industry. Federal funding has traditionally targeted a broad range of investigator-initiated research, from studies of molecular mechanisms of disease to population-based studies of disease prevalence, promoting an unrestricted environment of biomedical discovery that serves as the basis for industry-driven development. These approaches are complementary, and both have served society well.

    How, then, can we ensure that funding for biomedical research is maintained at adequate levels for the foreseeable future? Korn and colleagues have argued that stability and quality can be ensured by maintaining overall funding at an annual growth rate of 8 to 9 percent (unadjusted for inflation).3 They base their conclusion on the costs associated with six basic goals, which I endorse: preserving the integrity of the merit and peer-review process, which requires that funding levels not fall below the 30th percentile success rate; maintaining a stable pool of new investigators; sustaining commitments to continuing awards; preserving the capacity of institutions that receive grants by minimizing cost-sharing with the federal government (e.g., for lease costs or animal care); recognizing the continuous growth of new research technologies; and maintaining a robust intramural NIH research program. I would, however, modify the annual required growth rate to 5 to 6 percent real growth plus inflation: the annual growth rate over the past 30 years has been approximately 10 percent, which reflects an annual average real growth rate of 5.2 percent and an average inflation rate of 4.8 percent (ranging from 1.1 to 13.3 percent).

    Unfortunately, the federal government probably cannot accommodate this growth rate under its current fiscal constraints. So maintaining, by statute, a stable base level of funding equivalent to the fiscal year 2006 budget, with annual inflationary adjustments, seems to me a reasonable starting point. Congress may then choose to allocate additional resources annually, subject to availability, aiming for an annual real growth rate of 5 to 6 percent. Alternatively, to avoid politicization of the flow of funds and their targets, a dedicated tax could be imposed on consumer products that threaten human health — such as fast foods, tobacco, and alcohol — and used to maintain the biomedical research infrastructure by a formulaic allocation, much as the gasoline tax is used to maintain the federal highway infrastructure.

    The NIH can optimize the use of these funds by limiting the size and duration of awards as well as the number of awards per investigator. It might also consider shifting the target of grants. Whereas other countries often provide funding as an award for work accomplished before the application, the NIH theoretically funds proposed work — though in reality, the peer-review process effectively requires that a hypothesis virtually be proved correct before funding is approved. Within the NIH intramural research program, funding levels for individual laboratories are often decided on the basis of accomplishments during the previous cycle, so there is already a precedent that can be applied to the extramural program. Of course, new investigators would need to be reviewed differently to ensure appropriate allocation of funds to these promising members of the research community who have no or limited previous research accomplishments.

    Even with such changes, however, it would be preferable for academic medical centers to cease relying so heavily on the NIH for research funding. In addition to having investigators seek funding from not-for-profit organizations and from industry, I believe that centers should encourage major nongovernmental funding organizations to consolidate their resources into a durable pool of support for the best research proposals in the life sciences. In addition, individual centers should encourage generous donors to support unrestricted research endowments designed to fund translational and clinical research programs within the medical center or to contribute to a national pool linked with support from industry to establish a national endowment for funding translational research and drug or device development within academic medical centers. Such promotion of later-phase research within academic medical centers could enhance the value of the intellectual property derived from it, financial benefits from which could, in turn, be used to establish research endowments within the medical centers.

    The federal government might also consider alternative ways to fund the NIH budget that are independent of allocations from the tax base. One approach might include seeking support from industries whose products contribute to the burden of disease, providing tax credits as an incentive for their contribution. These resources could be used to establish an independently managed national fund, which could be used to ensure adequate support for biomedical research without the funding gaps or oscillations that currently plague the process. In this scenario, unused money from any fiscal year would be retained in the fund, with the goal of achieving self-sustained growth.

    Whatever mechanisms are ultimately chosen, it seems clear that new methods of support must be developed if biomedical research is to continue to thrive in the United States. The goal of a durable, steady stream of support for research in the life sciences has never been more pressing, since the research derived from that support has never promised greater benefits. The fate of life-sciences research should not be consigned to the political winds of Washington.
