Workforce projections for subspecialists in obstetrics and gynecology

Objective: To project the future supply of practicing subspecialists in obstetrics and gynecology based on the most recent numbers of physicians entering fellowships. Methods: A discrete actuarial model was developed, and supply projections were examined using 1999 subspecialty fellowship numbers from the American Board of Obstetrics and Gynecology. Results: The numbers of obstetrician-gynecologists entering subspecialty fellowships in maternal-fetal medicine (MFM) and reproductive endocrinology-infertility (REI) declined sharply between 1994 and 1999. There was a slow increase in gynecologic oncology (GO) fellows. Projections show that the numbers of practicing MFM and GO subspecialists will double by 2020, but they will be serving a 20% larger female population in the United States. Numbers of practicing REI subspecialists will increase slowly. Conclusion: The number of fellows in GO continues to enlarge progressively though slightly, whereas those in MFM and REI have fallen sharply in recent years. Among four possible factors affecting growth or decline, the ones that seem most important are existing career opportunities for both generalist and subspecialist obstetrician-gynecologists and the length of subspecialty education.
