Time for a little background and perspective.
This is a piece that was put out by the ASDS (American Society of Dermatologic Surgery). I know because until 2 years ago I was a member of the ASDS. Two of the doctors who spoke in the piece are high up in the chain, in fact, I think one of them is the current president of the ASDS.
Seven years ago the ASDS was concerned about the number of non-dermatologists and non-physicians who were getting in on what they see as their turf. There were a lot of articles and discussions about this issue in their internal publications and about 6 years ago, the word came out that they needed to combat this on the idea of patient safety. They came out with a campaign against what they call the non-physician practice of medicine (cosmetics in this case) and have been pursuing this issue and putting together a country wide media campaign about the issue. They also have a campaign against non-dermatologists, but that is another issue.
Where do the numbers come from. Well they come from what I would call non-science. They commissioned a survey where they asked all their members to report if they had seen an increase in complications from the non-physician practice of medicine. This is after all the articles and posturing. Interestingly enough in the first few go arounds only 50% of the physicians who responded to the survey actually said they saw an increase. So the 41% increase must come from a recent survey where they are still reporting seeing an increase. But without knowing the denominator, it is impossible to know what that means. Since there has been probably more than a 41% increase, this probably represents a real reduction. Furthermore every “real” study that has been attempted (and these are very hard to do) seems to imply that when you control for experience, that there is no difference between a physician doing the treatment, a non-physician in the presence of a physician, or a non-physician where there is no physician physically present.
And just to show you the mindset, I had a conversation with one of the physicians involved in this study and asked what is the definition of a reaction. In other words, how do you know what is a reaction so that you can report it. This is a very critical component of any good study and is necessary to be defined so that everyone in the survey are reporting the same thing. His answer, “We’re physicians, we all know what a reaction is.”
Note; There is an ironic twist to this tale. In liposuction, it is dermatologists who developed tumescent liposuction which is a very very safe procedure compared to general liposuction done under general anesthesia or IV sedation. Plastic surgeons prefer to do it the way they were trained and report a death rate of about 1 per 5,000 cases. On the other hand, there is no known death from tumescent anesthesia liposuction when performed under the guidelines of the dermatologists. There has been a turf battle over this between the surgeons and the dermatologists. There is no question from the research that has been done that what the dermatologists do is much safer. But the plastic surgeons have tried to limit dermatologists by insisting on hospital privileges (something dermatologists don’t routinely use or get) as a way of limiting dermatologists doing liposuction. So here is the irony. In this arena the dermatologists are insisting that real science be used and not the surveys that the plastic surgeons have commissioned concerned about patient safety. The lesson is that in the world of medicine, when you have the facts on your side you argue facts and statistics. When you don’t have the facts on your side, you argue patient safety.
As far as this report. No question that the tattoo removal reaction actually caused a keloid, which is a different mechanism and one that one has to be worried about concerning tattoo lasers. But it is also important to understand that tattoo lasers are very different from hair removal lasers. The mechanism of injury is more of a shock effect than a heat effect and are more likely to cause a scar. I believe that all lasers are not equal and that some are more likely to cause a complication than others. Tattoo is one of those lasers. There is a line to be drawn between lasers that can safely be used in cosmetic procedures by anyone and those that are riskier. I am not sure where that line should be drawn, but I tend to think it should be drawn on this side of tattoo lasers. In other words, those lasers may be too unsafe.
And as far as the laser hair removal pictures. First, those pictures have floated around the internet. Second, they were early in the reaction. Those types of reactions tend to clear up completely, though it can take months and months for the hyperpigmentation or hypopigmentation that follows to completely clear up. But they do routinely clear up. Notice that they didn’t show how they look long term. And finally, as was properly noted those were IPL burns.
