HISTORICAL OVERVIEW: INCREASING CONCERNS ABOUT DELEGATION
Prior to 1998, there exist few if any published reports regarding nonphysician performance of laser procedures.
1 Presumably, this dearth stemmed from the very small size of the laser business, which was the province of a few subspecialist physicians. Moreover, many commonly used lasers, such as those for hair removal and tattoo or pigment removal, had only recently been introduced, and their parameters of use were not standardized. The landscape has changed. As early as 8 to 10 years ago, reports documented the increasing tension between dermatologists and electrologists over the training required to perform laser hair removal, with dermatologists advocating that licensed physicians should supervise and be on-site; states, such as Texas, that do not require licensing for electrologists were a particular area of concern.

2 Yet concurrently, data was presented to show that “properly trained” nurses had no greater risk than physicians of inducing undesirable outcomes like pigmentation change and blistering after laser hair removal with long-pulsed alexandrite laser.
3 Most recently, the American Society for Dermatologic Surgery (ASDS) reported that more than 100 million laser and light-source cosmetic procedures were performed by its members.
4 And the increase appears to be even greater among nonphysician providers. More ominously, studies suggest that a proportionately greater amount of complications are arising from dermatologic care delivered by physician extenders.
Nearly 53% of 488 dermatologists surveyed in Texas in 2004 reported seeing increased complications associated with delegation to nonphysicians, with 33% of those surveyed asserting that they knew of such complications arising in the absence of a supervising physician on-site during treatment delivery.5 This confirmed earlier results of a survey of 2400 members of the ASDS in 2001, which ascribed the preponderance of posttreatment patient complications to “nonphysician operators,” including cosmetic technicians, estheticians, and workers in medical/dental offices who performed procedures for which they were not trained or during the performance of which they were inadequately supervised.6 A growing body of evidence suggests that nonphysician provision of laser services and insufficient physician oversight of extenders may be jeopardizing patients, unnecessarily raising complication rates, and leaving dermatologists vulnerable to public censure and legal liability.
