Abstract
The rapid growth of aesthetic medicine, particularly the use of hyaluronic acid (HA) dermal fillers, has outpaced the development of standardized educational pathways for Health Care Providers (HCPs), contributing to a wide variability in clinical practice and increased risk of adverse events. This Doctor of Nursing Practice (DNP) project aimed to evaluate the effectiveness of a structured, evidence-based educational intervention designed to improve provider knowledge and confidence in the prevention and management of HA filler complications. The intervention was developed using the 10-Point Plan framework and evaluated using the Kirkpatrick Model Levels 1 (Reaction) and 2 (Learning). A quasi-experimental, one-group pretest-posttest design was used with a convenience sample of seven aesthetic HCPs. Participants completed pre- and post-intervention assessments measuring knowledge and confidence across patient, product, and procedural domains, as well as a post-training satisfaction survey. Data were analyzed using Wilcoxon signed-rank tests and effect size calculations. Results demonstrated statistically significant improvements in the product domain (p < .05) and overall composite scores (p = .018), with large effect sizes observed across all domains. Although not all individual variables within the different domains reached statistical significance, consistent directional improvement and moderate-to-large effect sizes were noted. Participant satisfaction was high, with all participants reporting the training as valuable and clinically applicable. This project supports the feasibility and effectiveness of structured, evidence-based training programs in improving provider competency in aesthetic medicine. Findings highlight the need for standardized educational frameworks to enhance patient safety and reduce variability in clinical practice. Future research should evaluate long-term outcomes and impact on clinical behavior and patient safety.
