Outpatient utilization patterns for atopic dermatitis in the United States

Biologics and oral systemic treatment preferences in patients and physicians for moderate-to-severe atopic dermatitis: a discrete choice experiment in the United Kingdom and Germany

Background: As the available treatments for moderate-to-severe atopic dermatitis (AD) expand, understanding patient and physician preferences becomes crucial for informed decision-making.

Objective: To quantify patient and physician preferences for biologics and oral systemic AD treatment attributes.

Materials and methods: We conducted a cross-sectional, online discrete choice experiment (DCE) involving 306 AD patients and 206 physicians throughout the United Kingdom and Germany. Qualitative interviews identified the key attributes for inclusion in the DCE. Each choice task comprised two hypothetical patient profiles. Data were analyzed using a random-parameters logit model.

Results: Results indicated a significant emphasis on efficacy, with reducing sleep disturbance and itch ranking first and second among patients, and the reverse for physicians. Time to itch relief was the third most important efficacy attribute for both groups, but relatively more important for patients than for physicians. For both groups, the risk of eye problems was the most important safety concern of those included. Mode of administration was not of great importance compared to efficacy and safety attributes.

Conclusions: Our findings suggest patients prioritize sleep disturbance, an attribute not captured in prior preference studies in AD, time to itch relief and itch. These findings emphasize the importance of addressing sleep-related issues, whilst also targeting fast itch control, to enhance patients' well-being.

Time-dependent risk of atopic dermatitis following nontyphoidal Salmonella infection

BACKGROUND

The pathogenesis of atopic dermatitis (AD) remains unclear. Nontyphoidal Salmonella (NTS) infection might trigger immune-mediated reactions. We aimed to examine NTS and the risk of subsequent AD.

METHODS

From 2002 to 2015, eligible patients (aged 0-100 years) with NTS were identified. NTS and non-NTS groups were matched at a 1:10 ratio on age and sex. We utilized conditional multivariable Cox proportional hazard models to estimate the adjusted hazard ratio (aHR) and 95% confidence interval (CI) for AD development. Subgroup analyses were conducted based on age, sex, and severity of NTS infection. We utilized landmark analysis to explore the time-dependent hazard of AD following NTS.

RESULTS

In the NTS group (N = 6624), 403 developed AD. After full adjustment of demographics and comorbidities, the NTS group had a higher risk of AD than the reference group (aHR = 1.217, 95% CI = 1.096-1.352). Age-stratified analysis revealed that NTS group exhibited an elevated risk compared to the reference group, particularly among those aged 13-30 years (aHR = 1.25, 95% CI = 1.017-1.559), individuals aged 31-50 years (aHR = 1.388, 95% CI = 1.112-1.733), those aged 51-70 years (aHR = 1.301, 95% CI = 1.008-1.679), and individuals aged 71 years and over (aHR = 1.791, 95% CI = 1.260-2.545). Severe NTS was associated with a higher risk of AD than the reference group (aHR = 2.411, 95% CI = 1.577-3.685). Landmark analysis showed generally consistent findings.

CONCLUSIONS

Minimizing exposure to NTS infection may represent a prospective strategy for averting the onset and progression of atopic dermatitis.

Monoclonal antibodies for moderate-to-severe atopic dermatitis: a look at phase III and beyond

INTRODUCTION

The understanding of atopic dermatitis (AD) pathogenesis has rapidly expanded in recent years, catalyzing the development of new targeted monoclonal antibody treatments for AD.

AREAS COVERED

This review aims to summarize the latest clinical and molecular data about monoclonal antibodies that are in later stages of development for AD, either in Phase 3 trials or in the pharmacopoeia for up to 5 years, highlighting the biologic underpinning of each drug's mechanism of action and the potential modulation of the AD immune profile.

EXPERT OPINION

The therapeutic pipeline of AD treatments is speedily progressing, introducing the potential for a personalized medical approach in the near future. Understanding how targeting pathogenic players in AD modifies disease progression and symptomatology is key in improving therapeutic choices for patients and identifying ideal patient candidates.

Atopic dermatitis: A global health perspective

The International Society of AD (ISAD) organized a roundtable on global aspects of AD at the WCD 2023 in Singapore. According to the Global Burden of Disease (GBD) consortium, at least 171 million individuals were affected with AD in 2019, corresponding to 2.23% of the world population, with age-standardized prevalence and incidence rates that were relatively stable from 1990 to 2019. Based on the panel experience, most AD cases are mild-to-moderate. Without parallel data on disease prevalence and severity, the GBD data are difficult to interpret in many regions. This gap is particularly important in countries with limited medical infrastructure, but indirect evidence suggests a significant burden of AD in low-and-medium resource settings, especially urban areas. The Singapore roundtable was an opportunity to compare experiences in World Bank category 1 (Madagascar and Mali), 3 (Brazil, China) and 4 (Australia, Germany, Qatar, USA, Singapore, Japan) countries. The panel concluded that current AD guidelines are not adapted for low resource settings and a more pragmatic approach, as developed by WHO for skin NTDs, would be advisable for minimal access to moisturizers and topical corticosteroids. The panel also recommended prioritizing prevention studies, regardless of the level of existing resources. For disease long-term control in World Bank category 3 and most category 4 countries, the main problem is not access to drugs for most mild-to-moderate cases, but rather poor compliance due to insufficient time at visits. Collaboration with WHO, patient advocacy groups and industry may promote global change, improve capacity training and fight current inequalities. Finally, optimizing management of AD and its comorbidities needs more action at the primary care level, because reaching specialist care is merely aspirational in most settings. Primary care empowerment with store and forward telemedicine and algorithms based on augmented intelligence is a future goal.

Comparative efficacy of systemic treatments for atopic dermatitis in adults

INTRODUCTION

Atopic dermatitis is a prevalent skin condition causing dry, pruritic, inflammatory skin lesions that can result in patient distress. Various emerging classes of therapy, including biologics and Janus kinase inhibitors, have been developed in recent years.

AREAS COVERED

A literature search of PubMed was conducted to explore existing literature and clinical trials. Treatment options and adverse effects were summarized by class and severity. JAK inhibitors and biologics are efficacious options for adults with severe atopic dermatitis. Using the Eczema Area and Severity Index (EASI) from 11 randomized control trials, the highest efficacy was seen with upadacitinib 30 mg with 70% of patients achieving EASI-75. Older, immune-inhibiting treatment options are still appropriate options to improve patient conditions. A meta-analysis of 39 randomized control trials concluded high dose cyclosporine is more effective at improving quality of life and itch when compared to azathioprine and methotrexate. Newly developed topical and systemic medications improve disease and itch severity and can be considered in patients without adequate control with their initial treatment regimen. Adverse effects must be considered when using the newer options, although major adverse events were not seen.

EXPERT OPINION

Current management options are efficacious, but adherence is required for any effect.

Trends in Health Care Utilization Among United States Children With Eczema by Age, Sex, Race, and Hispanic Ethnicity: National Health Interview Survey 2006-2018

Background: Higher health care utilization has been proven among US children with eczema than those without, but disparities may exist among sociodemographic subgroups. Objective: To determine health care utilization trends among children with eczema across sociodemographic factors. Methods: We included children (0-17 years old) from the US National Health Interview Survey 2006-2018. We calculated the survey-weighted health care utilization by determining proportion of children attending a well-child checkup, seen by a medical specialist, and seen by a mental health professional in the previous 12 months for children with and without eczema, by race (white, black, American Indian/Alaska Native, Asian, and multiracial), Hispanic ethnicity (yes/no), age (0-5, 6-10, 11-17), and gender (male/female) subgroups using SPSS complex samples. Joinpoint regression was used to estimate piecewise log-linear trends in the survey-weighted prevalence, annual percentage change, and disparities between subgroups. Results: We included 149,379 children-there was higher health care utilization in children with eczema than those without. However, when comparing the average annual percentage change (AAPC), white children had a significantly higher AAPC of "attending a well-child checkup" than black children. In addition, only white children showed a significantly increasing trend in being "seen by a medical specialist," whereas all other minority race subgroups had stagnant trends. For those "seen by a mental health professional," there were increasing trends only in the male and non-Hispanic subgroups out of all the sociodemographic subgroups. Conclusion: Improving awareness among primary care physicians to refer children with moderate-to-severe eczema to medical specialists (eg, allergists, dermatologists, and mental health/attention-deficit/hyperactivity disorder professionals) when necessary could improve quality of life and reduce emergency department visits-especially among minority race, Hispanic, and female children.

Provision of Food Allergy Care in the United Kingdom and United States: Current Issues and Future Directions

Food allergy (FA) is a growing issue worldwide. The United Kingdom and United States are high-income, industrialized countries with reported increases in FA prevalence over the past few decades. This review compares delivery of FA care in the United Kingdom and United States and each country's response to the heightened demand and disparities for FA services. In the United Kingdom, allergy specialists are scarce and general practitioners (GPs) provide most allergy care. Whereas the United States has more allergists per capita than the United Kingdom, there is still a shortage of allergy services owing to the greater reliance on specialist care for FA in America and wide geographic variation in access to allergist services. Currently, generalists in these countries lack the specialty training and equipment to diagnose and manage FA optimally. Moving forward, the United Kingdom aims to enhance training for GPs so they may provide better quality frontline allergy care. In addition, the United Kingdom is implementing a new tier of semi-specialized GPs and increasing cross-center collaboration through clinical networks. The United Kingdom and United States aim to increase the number of FA specialists, which is critical at a time of rapidly expanding management options for allergic and immunologic diseases requiring clinical expertise and shared decision-making to select appropriate therapies. While these countries aim to grow their supply of quality FA services actively, further efforts to build clinical networks and perhaps recruit international medical graduates and expand telehealth services are necessary to reduce disparities in access to care. For the United Kingdom in particular, increasing quality services will require additional support from the leadership of the centralized National Health Service, which remains challenging.

The financial burden of out-of-pocket healthcare expenses on caregivers of children with atopic dermatitis in the United States

Background

Atopic dermatitis (AD) is associated with elevated financial costs, including out-of-pocket (OOP) expenses. Yet, the full burden of OOP expenses in children with AD is poorly understood.

Objectives

We sought to characterise categories, impact, and associations of caregiver-reported OOP AD healthcare expenses for US children.

Methods

An online survey was administered to National Eczema Association members (N = 113 502). Inclusion criteria (US resident; respondent age ≥18; self or caregiver report of AD diagnosis) was met by 77.3% (1118/1447) of those who completed the questionnaire.

Results

Caregivers of children (<18 years) with AD reported increased healthcare provider (HCP) visits, comorbid food allergy, cutaneous infections, and topical antimicrobial use (p < 0.005 for all), and increased OOP expenses for hospitalisation, emergency room visits, emollients, hygiene/bathing products, childcare, and specialised cleaning products, and clothing/bedding (p < 0.05 for all) compared to adults with AD. Children with AD had increased median total yearly OOP expenditures ($860 vs. $500, p = 0.002) and were more likely to spend ≥$1000 OOP per year (48.9% vs. 40.0%, p = 0.03). In children, yearly OOP expenses ≥$1000 were associated with increased AD severity, flares, HCP visits, prescription polypharmacy, and step-up therapy use (p < 0.005 for all) compared with adults. Predictors of harmful financial impact among children included black race (adjusted OR [95% confidence interval]: 3.86 [1.66-8.98] p = 0.002) and ≥$1000 annual OOP expenditures (6.98 [3.46-14.08], p < 0.0001).

Conclusion

Children with AD have unique and increased OOP expenses that are associated with significant disease burden. Strategies are needed to reduce OOP costs and improve clinical outcomes in children with AD.

Living with Atopic Dermatitis as a Young Adult in Relation to Health-related Quality of Life and Healthcare Contacts: A Population-based Study

Most studies of health-related quality of life (HRQoL) and atopic dermatitis are based on data from dermatology clinics. The aim of this study was to determine whether atopic dermatitis affects HRQoL in adolescence and young adulthood, based on data from the population-based cohort BAMSE (Children, Allergy, Environmental, Stockholm, Epidemiology). A further aim was to determine if the use of topical corticosteroids and healthcare contacts affect HRQoL. Participants with data from birth to young adulthood (n=3,064) were included. Two generic instruments were used to measure HRQoL:General Health at age 12, 16 and 24 years and EQ-5D-3L, including EQ-visual analogue scale (EQ-VAS) at age 24 years. In addition, the disease-specific Dermatology Quality Life Index (DLQI) was used at 24 years. Healthcare consultations for atopic dermatitis were obtained from Stockholm Regional Healthcare Data Warehouse (n = 1,944). Participants with atopic dermatitis had an increased odds ratio (OR) of not feeling completely healthy (adjusted OR 1.50; 95% confidence interval (95% CI): 1.30–1.73). Participants with persistent atopic dermatitis, fulfilling atopic dermatitis criteria in the 12- and/or 16- and 24-year follow-ups reported worse EQ-VAS value 70.0 (95% CI 67.3–72.7) in the 25^th percentile, than peers without atopic dermatitis. Over an 8-year period, contact with healthcare was limited (mean number 0.96). In conclusion, atopic dermatitis had a negative impact on HRQoL in young adults from adolescence to adulthood and healthcare consultations were few.

Dermatology for the internist: optimal diagnosis and management of atopic dermatitis

Internists are front-line health care providers that commonly provide the first encounter to patients for dermatological conditions, especially atopic dermatitis (AD). Internists need to be comfortable with managing mild-moderate AD in their practices. Criteria and guidelines established in dermatology literature are available to help the general practitioner diagnose and treat AD. AD is a systemic disease associated with multiple cutaneous and extra-cutaneous comorbidities that warrant screening by internists, especially mental health conditions. Environmental factors may play a role in the development or worsening of AD; however, there is currently no strong evidence to guide specific population- or clinic-based interventions for their avoidance. While food allergies are common in AD patients, the role of food allergens as an exacerbating factor for AD is controversial. Before starting any dietary modifications, careful evaluation should be performed by an allergist. If the patient is not well-controlled despite adequate topical therapies or is experiencing severe/worsening disease, early referral to dermatology is warranted to rule out confounding diagnoses and/or escalation to systemic therapies. Finally, it is important to recognise the racial disparities present in AD and address these when formulating treatment plans.Key messages:Confounding dermatoses, either instead of or in addition to AD, should be considered in treatment-refractory AD, and the appropriate workup may be initiated while awaiting dermatology referral.AD patients have multiple cutaneous and extra-cutaneous comorbidities that warrant screening by internists, especially mental health conditions.

Financial Burden of Atopic Dermatitis Out-of-Pocket Health Care Expenses in the United States

Background

Atopic dermatitis (AD) is associated with considerable financial cost. However, the full burden of out-of-pocket (OOP) expenses is not well understood.

Objective

We sought to characterize the OOP health care expenses associated with AD management.

Methods

A 25-question voluntary online survey was administered to National Eczema Association members worldwide (n = 113,502). Inclusion criteria (US residents age ≥18 years who either self-reported had AD or were primary caregivers of individuals with AD) were met by 77.3% (1118/1447) of respondents.

Results

Respondents reported OOP expenses in 3 categories: (1) health care providers and prescriptions, including health care provider visit deductibles (68.7% [686]), prescription co-pays (64.3% [635]), and prescriptions not covered by insurance (48.6% [468]); (2) nonprescription health care products, including moisturizers (94.3% [934]), hygiene products (85.0% [824], allergy medications (75.1% [715]), itch relievers (68.25% [647]), dietary supplements (52.2% [491]), and sleep aids (37.0% [336]); and (3) complementary approaches, including cleaning products (74.7% [732]), clothing/bedding (44.8% [430]), alternative medications (19.0% [180]), and adjunctive therapies (15.9% [150]). The median annual AD OOP expense was US $600 (range, US $0–$200,000), with 41.9% (364) reporting expenditures US $1000 or greater.

Conclusions

Out-of-pocket expenses place a significant financial burden on individuals with AD. Additional studies are needed to better understand associations and impact of OOP costs.

Financial burden and impact of atopic dermatitis out-of-pocket healthcare expenses among black individuals in the United States

Black race is associated with increased atopic dermatitis (AD) severity and healthcare resource utilization. However, the burden of out-of-pocket (OOP) expenses among black individuals with AD is not well understood. We sought to characterize the categories and impact of OOP healthcare expenses associated with AD management among black individuals. A 25-question voluntary online survey was administered to National Eczema Association members (N = 113,502). Inclusion criteria (US residents age ≥ 18 years; self-report of AD or primary caregivers of individuals with AD) was met by 77.3% (1118/1447) of respondents. Black individuals with AD were younger, had lower household income, Medicaid, urban residence, poor AD control and frequent skin infections (P ≤ 0.02). Blacks vs. non-blacks reported more OOP costs for prescription medications covered (74.2% vs. 63.6%, P = 0.04) and not covered (65.1% vs. 46.5%, P = 0.0004) by insurance, emergency room visits (22.1% vs. 11.8%, P = 0.005), and outpatient laboratory testing (33.3% vs. 21.8%, P = 0.01). Black race was associated with increased household financial impact from OOP expenses (P = 0.0009), and predictors of financial impact included minimally controlled AD (adjusted OR [95% CI] 13.88 [1.63-117.96], P = 0.02), systemic therapy (4.34 [1.63-11.54], 0.003), > $200 monthly OOP expenses (14.28 [3.42-59.60], P = 0.0003), and Medicaid (4.02 [1.15-14.07], P = 0.03). Blacks with Medicaid had higher odds of harmful financial impact (3.32 [1.77-6.24], P = 0.0002) than those of black race (1.81 [1.04-3.15], P = 0.04) or with Medicaid (1.39 [1.02-1.88], P = 0.04) alone. Black race is associated with increased OOP costs for AD and significant household financial impact. Targeted interventions are needed to address financial disparities in AD.

Who sees you matters: a population study examining topical corticosteroid prescribing patterns between primary care providers and dermatologists for atopic dermatitis

BACKGROUND

Many patients with atopic dermatitis seek care from both primary care physicians and dermatologists. However, little is known regarding topical corticosteroid prescribing patterns among these specialties.

OBJECTIVE

We sought to determine if differences exist in topical corticosteroid prescribing patterns among dermatologists, family medicine physicians, and internal medicine physicians.

METHODS

We conducted a population-based, cross-sectional analysis using data from the U.S. National Ambulatory Medical Care Survey from 2006 to 2016.

RESULTS

Compared to dermatologists, internal medicine physicians were 22 times less likely to prescribe a topical corticosteroid for atopic dermatitis (52.2% versus 5.1%, p = .001; adjusted OR 0.045, 95%CI 0.007-0.277). There was not a statistically significant difference in the rate of topical corticosteroid prescriptions for atopic dermatitis between family medicine physicians and dermatologists (39.1% vs. 52.2%, p = .27; adjusted OR 0.468, 95%CI 0.174-1.257). Family medicine physicians had a higher rate of prescribing topical corticosteroids for atopic dermatitis than internal medicine physicians (39.1% vs. 5.1%, p = .002).

LIMITATIONS

Severity of atopic dermatitis was not assessed.

CONCLUSIONS

Atopic dermatitis patients seen by internal medicine physicians are much less likely to receive topical corticosteroid prescriptions as compared to those seen by dermatologists.

Atopic Dermatitis in Adults

Atopic dermatitis (AD) was once thought to be a benign childhood disease that remitted with increasing age. However, recent studies have transformed the understanding of AD, particularly in adult patients. AD is common in adults and can lead to substantial disability by negatively affecting sleep, mental health, and quality of life. There seem to be different genetic, immunologic, and epidemiologic risk factors for AD in adults than in children. This article examines the pathophysiology, epidemiology, heterogeneous clinical presentation, burden, diagnosis, and treatment of adult AD.
