Patient Characteristics, Diagnostic Testing Utilization, and Antifungal Prescribing Pattern for Onychomycosis in the USA: A Cohort Study Using DataDerm, 2016-2022.

ABSTRACT:

Introduction

Onychomycosis is a complex nail disease that is commonly seen in daily practice.

Methods

Electronic health records of clinically diagnosed onychomycosis patients were extracted using DataDerm - a dermatology data registry hosted by the American Academy of Dermatology - spanning from the year 2016 to 2022.

Results

Regardless of age, an increasing trend in patient volume was observed in the Southern US region, which accounted for 50.7-56.9% of onychomycosis patients in 2022. A coinfection of tinea pedis was present among 15.6-22.5% of patients. Diagnostic testing was infrequently utilized with less than one-quarter of patients having a histopathologic examination (12.7-21.9%) followed by fungal culture (5.5-8.2%) and direct microscopic examination (3.3-6.0%
