Background US black and Hispanic populations are growing at a steady pace. In contrast, the medical profession lacks the same minority growth and representation. Women are also under-represented in many surgical disciplines. The purpose of this study was to assess trends in the proportion of women, blacks and Hispanics admitted to vascular surgery (VS) and related specialties, and to compare them to each other and to a surgical specialty, orthopedic surgery (OS), with a formal diversity initiative. Methods Data on the fellowship pool of VS, interventional radiology (IR), and interventional cardiology (IC), as well as the resident pools of general surgery (GS) and orthopedic surgery (OS) were obtained from US graduate medical education reports for 1999 through 2005. Cochrane-Armitage trend tests were used to assess trends in the proportion of females, blacks and Hispanics in relation to the total physician workforce for each subspecialty. Results No significant trends in the proportion of females, blacks or Hispanics accepted into VS and IC fellowship programs occurred during the study period. In contrast, IR, GS, and OS programs revealed significant trends for increasing proportions of at least one of the underrepresented study groups. In particular, OS, which has implemented a diversity awareness program, showed a positive trend in female and Hispanic trainees (P < .04 and P <.02, respectively). Blacks showed a significant increasing trend only in IR (P =.05). Conversely, a positive trend toward continued growth in the Hispanic group was seen in GS (P <.001), IR and OS (P =.04 and P =0.02, respectively). Conclusions The racial/ethnic and gender composition of the physician trainee pool in vascular specialties, particularly VS, has not matched the increasing growth of underrepresented groups in the US population of patients with vascular disease. Formal programs to recruit qualified women and minorities appear successful in increasing workforce diversity.

Peripheral arterial disease (PAD) is a highly prevalent public health problem associated with major detrimental effects on quality of life and functional status, and it is also the main cause of limb amputation. More importantly, PAD has been classified as a coronary artery disease equivalent, meaning that patients with a diagnosis of PAD carry a risk for major coronary events equal to that of established coronary artery disease. PAD is also a potent predictor of stroke and death. Despite its frequent occurrence (8 to 10 million Americans are affected), little is known about the natural history of PAD in racial/ethnic minorities, particularly in Hispanics, who represent 12.5% of the United States population. Furthermore, the disease is commonly underdiagnosed and undertreated in this minority group, and outcomes are poorer in Hispanics as compared with whites. Limited access to health care, difficulties for recruitment in population-based studies, and limitations of the noninvasive screening tests are well-established barriers to determine the prevalence and natural history of PAD in Hispanics. Although the most widely used test for assessment of patients at risk for PAD is the ankle-brachial index (ABI), the test has substantial limitations in individuals with diabetes and arterial calcification, which are highly prevalent in Hispanics. The ABI should, therefore, be supplemented by the use of other noninvasive tests, such as the pulse volume recordings (PVR) and toe-brachial index. Besides the use of a combination of diagnostic techniques, the implementation of a research methodology that improves recruitment of Hispanics in population-based studies is necessary to obtain better knowledge of the epidemiology of the disease in this group. Community-based participatory research may be the most appropriate approach to study this ethnic minority because it overcomes barriers for limited access to health care and increases the possibility of overcoming distrust of research on the part of communities. Understanding the epidemiology of PAD to improve its detection and treatment among Hispanics is relevant to reduce disparities in the health status of this group, the most rapidly growing ethnic minority in the United States.
