Since 1999, multiple surveys have documented a stable undersupply of dermatologic services in the United States. Factors contributing to the imbalance include changes in the demographics of the physician workforce, increased demand for services, and a limited number of training positions for new physicians. In response to the demand, there has also been a substantial influx of nonphysician clinicians into dermatology offices.

We sought to follow up the large data set collected by the American Academy of Dermatology in 2002; the survey was repeated in 2005 and 2007. Response rates ranged from 30% to 35% and included more than 1200 respondents each year.

Few changes were noted in the metrics used to assess the balance of supply and demand in the US dermatology workforce between 2002 and 2007. Mean wait times for new patient appointments decreased slightly from 36 to 33 days. One third of practices continue to seek additional dermatologists. In 2007, 23% of practices reported employing a physician assistant and 10% a nurse practitioner (up from 15% and 8% in 2002). In 2007, typical dermatologists continued to spend the bulk of their direct patient care time in medical dermatology (23.9 hours, 63%), followed by surgery (10.2 hours, 27%), and then cosmetic dermatology (3.8 hours, 10%). A substantial subset of dermatologists (29%) spent half or more of their time in surgical and cosmetic dermatology combined. Although female dermatologists worked fewer total hours, they spent equal time caring for patients with medical dermatologic conditions, less time in surgical dermatology, and more time in cosmetic dermatology.

The survey is potentially subject to inaccurate self-report and response bias. Although the results shed light on patient access and the dermatology workforce, they do not establish or quantify any impact on patients’ health.

Between 2002 and 2007, despite continued increases in the number of nonphysician clinicians in US dermatology offices, there were only small changes in the overall metrics commonly used to assess workforce balance. These findings suggest persistent unmet demand, but, given divergent trends of ongoing increases in surgical and cosmetic dermatology, growth in the use of physician assistants and nurse practitioners, and an aging and expanding US population, the future balance of supply and demand remains difficult to predict. Nevertheless, careful workforce planning and deliberative consideration of the risks and benefits of rapidly emerging changes in the delivery of dermatologic care are essential to ensure access to high-quality care for patients with skin disease.
