Background: The Mobile Clinic Project (MCP) is a student-run clinic that offers free medical services directly on the streets, reaching those who may face barriers to accessing traditional healthcare facilities. Dermatologic issues can pose significant challenges for this population, as they are exposed to environmental factors that may exacerbate skin conditions, such as harsh weather conditions and limited access to healthcare. 

Objective: This study aims to evaluate the prevalence of skin conditions and treatments to develop tailored quality improvement strategies.

Methods: We performed a retrospective medical chart review using data from January 1, 2022, to February 28, 2024. The study included patients aged 18 years and older who were treated at MCP for dermatologic issues. Demographic and clinical data were summarized using descriptive statistics and measures of central tendency.

Results:  Out of 437 medical visits, 34.5% (n=202) sought treatment for dermatologic concerns. The median patient age was 49 years, with a male and BIPOC predominance (Latinx, African American/Black). Common dermatologic diagnoses included cellulitis, abscesses, atopic dermatitis, fungal infections, rashes, open wounds, scabies, and unspecified pruritus. Tinea pedis and onychomycosis also were frequently observed. Treatment modalities were primarily over-the-counter medication with hydrocortisone cream being the most heavily prescribed medication in the clinic besides NSAIDs. Permethrin cream 5% and oral antibiotics including doxycycline, cephalexin, and trimethoprim/sulfamethoxazole were most picked up from the local pharmacy.

Conclusions: MCP predominantly serves unhoused individuals largely from underrepresented minority backgrounds for a range of dermatologic concerns. The prevalence of soft skin tissue infections underscores the need for sufficient resources, particularly antibiotics and wound care supplies, to address the ongoing health needs of our patients. Recognizing the burden of foot-related conditions, we partnered with a podiatry student-run clinic to provide specialized services, furthering our commitment to tailored healthcare.
