Delusions of Parasitosis in Dermatology Residency Education: A Survey Outcome Study of a Targeted Didactic on Prescribing Antipsychotics
ABSTRACT
Background:
Delusions of parasitosis (DP), a somatic delusion involving false beliefs of infestation, frequently presents in dermatologic rather than psychiatric settings. While antipsychotics are the cornerstone of treatment, most dermatologists report discomfort with prescribing them, and psychopharmacology is not routinely taught in dermatology training.
Objective:
The aim of this study is to evaluate the impact of a brief, targeted educational video on dermatology residents’ knowledge and confidence in managing DP with antipsychotics.
Methods:
Residents from dermatology programs across the United States were recruited to watch our video didactic and complete pre- and post-test surveys to assess objective knowledge and subjective preparedness.
Results:
Twenty-four residents completed the study. Results showed significant improvements in both objective and subjective domains: mean knowledge scores increased from 1.83 to 4.42 out of 5 (P < 0.001, Cohen’s d = 2.45), and Likert-rated confidence in managing DP and understanding prescribing considerations increased with large effect sizes (r > 0.75).
Conclusions:
These findings support the integration of psychopharmacology into dermatology residency curricula to improve care accessibility for patients with psychocutaneous disorders.
