Identifying Levels of Competency in Aesthetic Medicine: A Questionnaire-Based Study.

Abstract

In 2022, the US experienced a significant increase in demand for minimally invasive aesthetic procedures, underscoring its rising acceptance amidst an unregulated educational environment for practitioners. The absence of standardized educational pathways and quality control in aesthetic medicine, primarily provided by non-academic institutions, highlights a critical need for establishing educational standards to ensure practitioner competence and patient safety. To identify levels of competency for the aesthetic practitioner and for necessary achievement milestones during the educational path from novice to expert injector. A total of n = 386 international study participants responded to an online questionnaire regarding their experience in aesthetic medicine practice. The questionnaire comprised 58 questions focusing on professional data, the perceived difficulty of injection and risk for the occurrence of adverse events for specific facial regions in soft tissue filler and toxin injections. Regardless of medical specialty and experience level, an average of 3.85 (1.8) years, 786.4 (2,628) filler injections, and 549.9 (1,543) toxin injections was estimated to progress from novice to advanced injector, while an average of 6.10 (3.7) years, 1,842.2 (4,793) filler injections, and 1,308.5 (3,363) injections was estimated to advance from advanced to expert injector. The nose and the perioral region have been ranked as the facial regions most difficult to achieve a perfect aesthetic outcome and with the greatest risk for the occurrence of adverse events for filler and toxin injections, respectively. This study establishes an educational framework in aesthetic medicine by defining the progression from novice to competent and expert injector levels, suggesting 4 years of practice and over 790 filler and 550 neuromodulator injections for competence, and at least 6 years with 1,840 filler and 1,310 neuromodulator injections for expertise. It also identifies critical facial regions for targeted treatments by different expertise levels.
