There is limited information about minority representation throughout the plastic and reconstructive surgery (PRS) pipeline. The aim of this study was to examine trends in representation among minorities at different stages of the PRS training pathway, starting with potential candidates in high school through practicing physicians. The PRS pipeline was defined as high school; college; medical school applicants, matriculants, and graduates; PRS residency applicants, matriculants, and active residents; and PRS practicing physicians. Racial data for each stage were obtained from the US Census and Association of American Medical Colleges. The proportion of races at each stage were divided by their US population counterpart proportions to produce representation quotients (RQs). Medians and interquartile ranges (IQRs) are reported. Mann-Whitney U tests compared RQ values within identities between successive stages. Black students had high representation in high school (RQ = 1.26 [IQR: 1.21-1.29]) but had significant, stepwise decreases in representation in subsequent stages. A similar trend was observed for Hispanic individuals, who had their highest representation in high school (1.43 [1.37-1.50]), followed by significant decreases in RQ at nearly every subsequent stage up to and including practicing physicians (0.30 [0.28-0.31). Asian individuals were overrepresented at every stage (high school RQ: 1.01 [1.00-1.03]; practicing physician RQ: 2.30 [2.27-2.32]). White individuals were underrepresented before residency but had an RQ that approximated 1 in subsequent stages. Racial minorities experienced decreases in representation at each successive stage in the PRS pipeline following high school. Ongoing diversity efforts should focus on premedical recruitment and professional support for minority students.
