A Cross-Sectional Evaluation of Chronic Urticaria Training in Dermatology Residency
Despite most U.S. dermatology residents reporting adequate training in chronic urticaria, a significant gap exists between their perceived confidence and their actual adherence to clinical guidelines, particularly regarding the use of validated outcome measures and evidence-based diagnostic practices.

Chronic urticaria is a skin condition where a person develops itchy, raised welts, often called hives, that persist for more than six weeks. Unlike a sudden allergic reaction to a peanut or a bee sting that fades quickly, this condition lingers, appearing and disappearing without a clear trigger in many cases. For the roughly one percent of people worldwide who live with it, the condition is more than a skin irritation; it is a source of constant discomfort that can disrupt sleep, work, and daily life. While doctors have established rules for how to diagnose and treat these persistent hives, the way these rules are applied in real clinics can vary widely. The gap between what medical guidelines say should happen and what actually happens in a doctor's office is a significant concern, especially because the people learning to become specialists are the ones who will eventually set the standard for care.
A team of researchers at George Washington University decided to look directly at the training of future dermatologists to see if this gap begins during their education. They sent an anonymous survey to 1,750 dermatology residents across the United States, asking them about their experience with chronic urticaria, how much they knew about the official treatment guidelines, and how confident they felt when treating patients. The survey reached 411 residents, a response rate of about twenty-four percent, and the results painted a picture of a training environment that is generally adequate but leaves specific, important holes in knowledge and practice.
Most of the residents who answered the survey were in their third or fourth year of training, meaning they had spent several years in medical school and were deep into their specialty education. When asked if they had received enough education on chronic urticaria, nearly three-quarters said yes. They reported learning about the condition through lectures, clinical rotations, and reading. They also felt reasonably confident in their ability to figure out what was wrong with a patient and how to treat them. However, when the researchers asked specific questions about the guidelines that doctors are supposed to follow, the picture changed. More than half of the residents said they were not aware of the official United States guidelines, and nearly eighty percent did not know about the European guidelines. Even more telling, about half of the respondents admitted they did not actually follow any specific guidelines when treating patients, relying instead on their own experience or what they had seen others do.
The way these future doctors approached the diagnosis of the condition also showed a tendency to order more tests than necessary. Medical guidelines suggest a focused approach: a basic blood count and a check for inflammation are usually enough to start. Yet, many residents reported routinely ordering a wide array of additional tests, including checks for thyroid issues, autoimmune diseases, and various infections, even when there was no specific reason to suspect them. This suggests a hesitation to trust a limited workup, perhaps driven by a fear of missing a hidden cause. Furthermore, the residents rarely used standardized tools to measure how much the condition was bothering the patient. These tools, which ask patients to rate their own symptoms and quality of life, are recommended to help doctors track progress, but fewer than twenty-five percent of the residents said they used them.
When it came to treatment, the residents were generally on the right track with the first steps. Most correctly identified that the first line of defense should be non-drowsy antihistamine pills, and they knew that if the standard dose did not work, the dose could be safely increased up to four times the normal amount. This aligns with current medical advice. However, once the first line of treatment failed, the choices became inconsistent. While some residents moved to newer, targeted medications that block specific immune pathways, others still relied on older treatments like corticosteroids, which guidelines recommend using only for very short periods during severe flare-ups. A significant number of residents also reported referring their patients to allergy and immunology specialists for help with these advanced treatments. While collaboration is valuable, the high rate of referral suggests that many residents feel uncomfortable managing these cases themselves, even though the condition falls squarely within the scope of dermatology.
The study concludes that while dermatology residents are getting exposure to chronic urticaria and feel confident in their general abilities, their training is not fully translating into strict adherence to evidence-based guidelines. The gaps in knowledge regarding official rules, the overuse of broad testing, and the hesitation to manage advanced therapies independently point to a need for more focused education. The researchers suggest that strengthening the curriculum to emphasize guideline-directed care and the use of patient-reported tools could help ensure that the next generation of dermatologists is better equipped to manage this chronic and life-disrupting condition without unnecessary tests or referrals.
