and quality of applications submitted but also by available funding.

The success of AIDS research applications has varied from institute to institute. At NIMH, AIDS grants (traditional investigator-initiated grants—R01s) have had higher success rates than non-AIDS grants; however, those success rates fell from 35.1 in 1989 to 13.5 in 1993 (Figure 5.6). At NIDA, AIDS grants (all RPGs) had higher success rates than non-AIDS grants in 1990, 1991 and 1993, but lower success rates in 1989 and 1992 (Figure 5.7). In general, NIDA RPGs consistently have had relatively high success rates (in the range of 28.4 to 41.1). Since the number of AIDS applications at NIAAA has been relatively small, the success rates may fluctuate dramatically from one year to the next (Figure 5.8). For example, in FY 1990, NIAAA received three competing AIDS applications and funded all of them. During the following year, NIAAA funded 6 of the 19 applications it received. In general, data for all institutes indicate that success rates for all research are declining, which is more likely a result of shrinking budgets and rising per-grant costs than of declining quality among grant proposals submitted.
