Is there a medical/legal requirement for charting details of a cosmetic Botox procedure, i.e., what brand of Botulinum Toxin used, it's dilution ratio, expiration date, lot number, etc. If so, what are the repercussions of not following protocol?
No there is no legal requirement. Typically the doctor will document the amount injected and locations and the discussion of the risks. My office does not chart expiration date and lot number in the individual patient chart but keeps track of bottles in a office log, and there is no legal reason or need to do so. The brand of neurotoxin though should be charted. Each doctor may have his own preference how to prepare it, and as long as the number of units is used, the dilution ratio is not significant and there is a range. In the United States any physician, and in some states dentists and nurse practitioners can inject Botox, and in many can delegate anyone in their office to inject. Some you neither have to be a physician or nurse to inject. So it is up to the patient to do their homework and ask who is injecting, and their residency training and beware of embellished resumes. There would be no repercussions to any of the questions you mention, unless no charting of any kind .
Thank you for sharing your question. Although not mandated, most practices do maintain this information on patients as part of their medical record.
