Pharmacy and American Society of Health-System Pharmacists (ASHP). Design. Prospective survey analysis. Data Source. The ASHP Online Residency Directory was used to obtain PGY1

residency program data from June 2007–June 2008. A four-item questionnaire was developed to survey future residency growth in identified PGY1 programs. Measurements and Main Results. Survey data were aggregated to project future residency growth in the “next few years ” (range 2–4 yrs). Estimates of Doctor of Pharmacy (Pharm.D.) graduates to 2020 were used to calculate PGY1 residency positions and average annual growth rates required if 24% (scenario 1), 75 % (scenario 2), and 100 % (scenario 3) of pharmacy graduates pursue PGY1 residencies. Projected growth from the survey was compared with required growth under the scenarios, as well as with actual PGY1 growth from June 2007–June 2008. A subset analysis of college-affiliated and Veterans Affairs (VA) PGY1 programs was performed. The survey response rate was 57%. The PGY1 positions were projected to increase by 8.3%/year in the next few years or 4193 positions by 2020 if 8.3 % growth is sustained. Required average annual growth rates for scenarios 1–3, respectively, were 4.8%, 14.4%, and 17%. Projected growth rates were sufficient to achieve onl
