XIII. Report on the P-Series and R-Series Mechanisms

Dr. Cooper

Dr. Judith A. Cooper, Deputy Director of the Division of Human Communication, NIDCD, reported on the P-Series and R-Series Mechanisms, in response to previous questions from Council members.

She began her report by defining each of the three mechanisms, and addressing the differences and similarities among R01s, P01s and P50s. These mechanisms differ in several ways, including the budget lines from which they are paid; how they are scored; the committees responsible for reviewing them; budgetary caps; their relative representation in the NIDCD portfolio; and what percentage of the Instituteís budget is allocated to each mechanism.

Dr. Cooper discussed recent submission and funding trends related to each mechanism, in order to clarify the growth, stability or decline in each one. Dr. Cooper summarized her presentation by making the following points:


  • the actual dollars spent on P01s have gradually decreased since FY 1993. Since NIDCDís overall budget has increased each year, that constitutes both a relative and absolute decrease in percent and thus, the percent of RPG dollars going to P01s in the past 4 years has decreased, from 22 percent to 17 percent;


  • the number of competing P01 applications funded each year dropped between FY 1993, when six were funded, and FY 1996, when only two were funded;


  • the R01 mechanism is healthy, growing, and has received an increasing proportion of available dollars each year over the past four years;


  • the P50, Clinical Research Center Program, has remained stable both in numbers of submissions and awarded dollars over the past few years;


  • the percentage of the NIDCD budget spent on all large, multiproject P grants has dropped over the years, from 32 percent in FY 1992 to 27 percent in FY 1996;


  • the number of high-cost R01s is very small, with the majority of NIDCD grants having direct costs between $100,000 and $200,000. In general, NIDCD R01 grants have tended to be less costly than overall NIH averages for R01s.
