Transport Woes and Health Literacy, Not Skin Stage, Drive Misery in Hidradenitis Suppurativa

Hidradenitis suppurativa is one of dermatology’s most punishing diseases: a chronic inflammatory condition in which painful nodules and abscesses erupt repeatedly in intertriginous regions, the warm, folded areas of skin where surfaces rub together. Yet for all its physical toll, the factors that most shape how badly patients feel their lives are going have remained surprisingly murky. A new cross-sectional digital survey published in the Archives of Dermatological Research now suggests that the answer may lie less in the clinic’s staging charts and more in the mundane logistics of everyday life, including whether a patient can reliably get to an appointment and whether they can understand the instructions handed to them at the pharmacy counter.

The study, led by Olivia Babich of the University of Pittsburgh School of Medicine with colleagues including senior author Sonal Choudhary of the University of Pittsburgh Medical Center, set out to fill a persistent gap. Despite the prevalence and impact of hidradenitis suppurativa, the authors note, there remains a paucity of patient-oriented data directly analyzing demographic and socioeconomic factors and their association with quality of life. Much of the existing literature focuses on clinical measures, comorbidities, or treatment response, leaving the lived texture of the disease, the missed buses, the confusing leaflets, the appointments that never happen, largely unmeasured.

To capture that texture, the team consecutively identified patients with hidradenitis suppurativa and sent them a digital survey covering their experiences living with the condition, their assessment of treatment success, and their interactions with the healthcare system. The instrument incorporated the Dermatology Life Quality Index, a validated questionnaire that scores the impact of skin disease across daily activities, symptoms, and emotional wellbeing. Crucially, the researchers did not rely on self-report alone: they also extracted electronic medical record data, including each participant’s Hurley stage, the standard three-tier system clinicians use to grade hidradenitis suppurativa severity from localized nodules to widespread abscesses, scarring, and interconnected sinus tracts.

The recruitment numbers tell their own story about the burden of the disease. Of 343 patients approached between January 2022 and January 2025, 102 completed the survey, a response rate of 29.7 percent. The final cohort had a mean age of 38.6 years with a standard deviation of 11.1, and only 12 participants, or 11.8 percent, were male, a distribution consistent with the condition’s well-documented female predominance. The survey was administered through a research electronic data capture platform, and the study received a formal exemption from the University of Pittsburgh Institutional Review Board on August 4, 2023, with all participants providing written informed consent before taking part.

The statistical heart of the paper lies in its univariate and multivariate analyses, which tested associations between patient variables and disease outcomes. Participants whose Dermatology Life Quality Index scores exceeded 10, a threshold generally interpreted as indicating a severe effect of skin disease on life quality, shared a distinctive profile. They were typically diagnosed at a younger age, with an odds ratio of 0.957 per year of age at diagnosis, a 95 percent confidence interval of 0.916 to 0.999, and a p value of 0.047. In practical terms, each additional year of age at diagnosis slightly reduced the odds of falling into the high-burden group, implying that earlier onset marks a more disruptive disease trajectory.

Two socioeconomic variables stood out even more sharply. Patients who reported concerns regarding transportation access had nearly five and a half times the odds of a Dermatology Life Quality Index above 10, with an odds ratio of 5.471 and a 95 percent confidence interval of 1.440 to 20.783, reaching significance at p equals 0.013. And those who more often required assistance when reading written material from their doctor or pharmacy had more than six times the odds, an odds ratio of 6.298 with a confidence interval of 1.194 to 33.238 and a p value of 0.030. Wide confidence intervals reflect the modest sample size, but the direction of both associations is consistent with a broader literature linking social determinants of health to outcomes in chronic inflammatory disease.

Perhaps the most provocative finding is what did not predict quality of life. Higher Dermatology Life Quality Index scores, the authors report, were significantly associated with several participant factors, including poorer understanding of written material from doctors or pharmacies, lower attendance rates at scheduled medical appointments, and lack of access to reliable transportation. Hurley stages, by contrast, were not. In other words, the anatomical severity a dermatologist documents in the chart did not track with how devastating patients found the disease, while the practical frictions of navigating care did. For a condition in which flares are painful, recurrent, and often hidden beneath clothing, that disconnect between clinical staging and patient experience carries real weight.

The finding resonates with a growing body of work on hidradenitis suppurativa’s wider footprint. Recent studies have linked the disease to cardiometabolic comorbidities in diverse safety-net populations, to psychiatric disease in systematic reviews and meta-analyses, and to markedly increased healthcare utilization among patients of color, where racial disparities in management have been documented at single institutions. Diagnostic delay remains, as one 2024 review put it, still an unsolved problem, and the new result adds a mechanistic hint: if patients struggle to read discharge instructions or cannot count on a ride to clinic, the delays and missed appointments that worsen outcomes may begin long before any biologic therapy is chosen.

The study’s methodology deserves both credit and caution. Pairing patient-reported survey responses with electronic medical record data, including physician-assigned Hurley stages, is a methodological strength that many quality-of-life surveys lack, anchoring subjective burden to objective clinical documentation. But the investigators are candid about the limits. The single-center design, the modest sample of 102 respondents, and the possibility that sicker or more frustrated patients were more motivated to respond all constrain generalizability. The authors explicitly describe the work as exploratory and hypothesis-generating in nature, and they caution that additional research involving patient-reported outcomes and relationships between patient factors and disease course is needed to aid in the development of more effective and comprehensive care plans.

Even so, the message for clinicians is hard to ignore. Screening a hidradenitis suppurativa patient for transportation insecurity or low health literacy may, according to these data, tell you more about their quality of life than another glance at their skin. The research was supported by the University of Pittsburgh Clinical and Translational Science Institute through the National Institutes of Health Clinical and Translational Science Award program under grant UL1 TR001857, and the team suggests that simple interventions, plain-language written materials, transportation assistance, and flexible scheduling, could be tested as complements to medical therapy. For a disease that has long been measured in nodules and tracts, the new survey argues that the most meaningful severity score may be written not on the skin, but in the obstacles a patient faces on the way to care.
