Atopic Dermatitis

Key clinical point: Interruption of upadacitinib treatment caused rapid loss of skin clearance response and upadacitinib retreatment led to rapid recovery or improvement in the response in patients with moderate-to-severe atopic dermatitis (AD).

Major finding: A dose of 30 mg upadacitinib vs placebo led to a 72.9% least-squares mean percentage improvement in the Eczema Area and Severity Index (EASI) score by week 16, which decreased to 24.6% within 4 weeks of upadacitinib withdrawal; however, an 8-week rescue therapy (30 mg upadacitinib) improved the mean percentage EASI score (pre- vs post-therapy: 2.8% vs 84.7%).

Study details: This post hoc analysis of a phase 2b study included 167 patients with moderate-to-severe AD who were randomly assigned to receive upadacitinib (7.5, 15, or 30 mg) or placebo; at week 16, each group was reassigned to receive upadacitinib (same dose) or placebo, with rescue therapy (30 mg upadacitinib) initiated in those with < 50% EASI response at week 20.

Key clinical point: Nemolizumab is safe and effectively reduces pruritus in pediatric patients with atopic dermatitis (AD) whose pruritus has not been sufficiently improved with topical corticosteroids/calcineurin inhibitors or antihistamines.

Major finding: At week 16, the nemolizumab vs placebo group had a significantly greater improvement in the weekly mean 5-level itch score (−1.3 vs −0.5; P < .0001), with a significantly higher proportion of patients achieving a weekly mean 5-level itch score ≤ 1 (24.4% vs 2.3%; P = .0035). Most adverse events were mild in severity and none led to treatment discontinuation or death.

Study details: Findings are a from multicenter phase 3 study including patients age 6-12 years with AD and inadequately controlled moderate-to-severe pruritus who were randomly assigned to receive nemolizumab (n = 45) or placebo (n = 44) with concomitant topical agents.

Atopic dermatitis (AD) is a common inflammatory skin disease that may severely decrease quality of life (QOL) and lead to psychiatric comorbidities.^1-3 Prior studies have indicated that AD causes a substantial economic burden, and disease severity has been proportionally linked to medical costs.^4,5 Results of a multicenter cost-of-illness study from Germany estimated that a relapse of AD costs approximately €123 (US $136). The authors calculated the average annual cost of AD per patient to be €1425 (US $1580), whereas it is €956 (US $1060) in moderate disease and €2068 (US $2293) in severe disease (direct and indirect medical costs included).⁶ An observational cohort study from the Netherlands found that total direct cost per patient-year (PPY) was €4401 (US $4879) for patients with controlled AD vs €6993 (US $7756) for patients with uncontrolled AD.⁷

In a retrospective survey-based study, it was estimated that the annual cost of AD in Canada was approximately CAD $1.4 billion. The cost per patient varied from CAD $282 to CAD $1242 depending on disease severity.⁸ In another retrospective cohort study from the Netherlands, the average direct medical cost per patient with AD seeing a general practitioner was US $71 during follow-up in primary care. If the patient needed specialist consultation, the cost increased to an average of US $186.⁹

We aimed to assess the direct and indirect medical costs in adult patients with moderate to severe AD who attended a tertiary health care center in Finland. In addition, we evaluated the impact of AD on QOL in this patient cohort.

Methods

Study Design—Patients with AD who were treated at the Department of Dermatology and Allergology, Helsinki University Hospital, Finland, between February 2018 and December 2019 were randomly selected to participate in our survey study. All participants provided written informed consent. In Finland, patients with mild AD generally are treated in primary health care centers, and only patients with moderate to severe AD are referred to specialists and tertiary care centers. Patients were excluded if they were younger than 18 years, had AD confined to the hands, or reported the presence of other concomitant skin diseases that were being treated with topical or systemic therapies. The protocol for the study was approved by the local ethics committee of the University of Helsinki.

Questionnaire and Analysis of Disease Severity—The survey included the medical history, signs of atopy, former treatment(s) for AD, skin infections, visits to dermatologists or general practitioners, questions on mental health and hospitalization, and absence from work due to AD in the last 12 months. Disease severity was evaluated using the patient-oriented Rajka & Langeland eczema severity score and Patient Oriented Eczema Measure (POEM).^10,11 The impact on QOL was evaluated by the Dermatology Life Quality Index (DLQI).¹²

Medication Costs—The cost of prescription drugs was based on data from the Finnish national electronic prescription center. In Finland, all prescriptions are made electronically in the database. We analyzed all topical medications (eg, topical corticosteroids [TCSs], topical calcineurin inhibitors [TCIs], and emollients) and systemic medicaments (eg, antibiotics, antihistamines, cyclosporine, methotrexate, and corticosteroids) prescribed for the treatment of AD. In Finland, dupilumab was introduced for the treatment of severe AD in early 2019, and patients receiving dupilumab were excluded from the study. Over-the-counter medications were not included. The costs for laboratory testing were estimations based on the standard monitoring protocols of the Helsinki University Hospital. All costs were based on the Finnish price level standard for the year 2019.

Inpatient/Outpatient Visits and Sick Leave Due to AD—The number of inpatient and outpatient visits due to AD in the last 12 months was evaluated. Outpatient specialist consultations or nurse appointments at Helsinki University Hospital were verified from electronic patient records. In addition, inpatient treatment and phototherapy sessions were calculated from the database.

We assessed the number of sick leave days from work or educational activities during the last year. All costs of transportation for doctors’ appointments, laboratory monitoring, and phototherapy treatments were summed together to estimate the total transportation cost. Visits to nurse and inpatient visits were not included in the total transportation cost because patients often were hospitalized directly after consultation visits, and nurse appointments often were combined with inpatient and outpatient visits. To calculate the total transportation cost, we used a rate of €0.43 per kilometer measured from the patients’ home addresses, which was the official compensation rate of the Finnish Tax Administration for 2019.¹³

Statistical Analysis—Statistical analyses were performed using SPSS Statistics 25 (IBM). Descriptive analyses were used to describe baseline characteristics and to evaluate the mean costs of AD. The patients were divided into 2 groups according to POEM: (1) controlled AD (patients with clear skin or only mild AD; POEM score 0–7) and (2) uncontrolled AD (patients with moderate to very severe AD; POEM score 8–28). The Mann-Whitney U statistic was used to evaluate differences between the study groups.

Results

Patient Characteristics—One hundred sixty-seven patients answered the survey, of which 69 (41.3%) were males and 98 (58.7%) were females. There were 16 patients with controlled AD and 148 patients with uncontrolled AD. Three patients did not answer to POEM and were excluded. The baseline characteristics are presented in Table 1 and include self-reported symptoms related to atopy.

The most-used topical treatments were TCSs (n=155; 92.8%) and emollients (n=166; 99.4%). One hundred sixteen (69.5%) patients had used TCIs. The median amount of TCSs used was 300 g/y vs 30 g/y for TCIs (range, 0-5160 g/y) and 1200 g/y for emollients.

Fifteen (9.0%) patients had been hospitalized for AD in the last year. The mean (SD) length of hospitalization was 6.5 (2.8) days. Thirty-four (20.4%) patients received UVB phototherapy. Thirty-four (20.4%) patients were treated with at least 1 antibiotic course for secondary AD infection. Thirty-six (21.6%) patients needed at least 1 oral corticosteroid course for the treatment of an AD flare.

Fifteen (9.0%) patients reported a diagnosed psychiatric illness, and 17 (10.2%) patients were using prescription drugs for psychiatric illness. Forty-nine (29.3%) patients reported anxiety or depression often or very often, 54 (32.3%) patients reported sometimes, 33 (19.8%) patients reported rarely, and only 30 (18.0%) patients reported none.

Medication Costs—Mean medication cost PPY was €457.40 (US $507.34)(Figure 1 and Table 2). On average, one patient spent €87.50 (US $97.05) for TCSs, €121.90 (US $135.21) for emollients, and €225.10 (US $249.68) for TCIs. The average cost PPY for antibiotics was €6.10 (US $6.77). Other systemic treatments, including (US $18.65). Seventeen patients (10.2%) were on methotrexate therapy for AD in the last year, and 1 patient also used cyclosporine. The costs for laboratory monitoring in these patients were included in the direct cost calculations. The mean cost PPY of laboratory monitoring in the whole study cohort was €6.60 (US $7.32). In patients with systemic immunosuppressive therapy, the mean cost PPY for laboratory monitoring was €65.00 (US $72.09). Five patients had been tested for contact dermatitis; the costs of patch tests or other diagnostic tests were not included.

Visits to Health Care Providers—In the last year, patients had an average of 1.83 dermatologist consultations in the tertiary center (Table 2). In addition, the mean number of visits to private dermatologists was 0.61 and 1.42 visits to general practitioners. The mean cost of physician visits was €302.70 (US $335.75) in the tertiary center, €66.60 (US $73.87) in the private sector, and €141.90 (US $157.39) in primary health care. In total, the average cost of doctors’ appointments PPY was €506.30 (US $561.57). The mean estimated distance traveled per visit was 9.5 km.

The mean cost PPY of inpatient treatments was €329.90 (US $365.92) and €239.00 (US $265.09) for UV phototherapy. Only 4 patients had visited a nurse in the last year, with an average cost PPY of €2.50 (US $2.78).

In total, the cost PPY for health care provider visits was €1084.20, which included specialist consultations in a tertiary center and private sector, visits in primary health care, inpatient treatments, UV phototherapy sessions, nurse appointments in a tertiary center, and laboratory monitoring. The average transportation cost PPY was €34.00 (US $37.71). The mean number of visits to health care providers was 8.3 per year. Altogether, the direct cost PPY in the study cohort was €1580.60 (US $1752.39)(Table 2 and Figure 2).

Comparison of Medical Costs in Controlled vs Uncontrolled AD—In the controlled AD group (POEM score <8), the mean medication cost PPY was €567.15 (US $629.13), and the mean total direct cost PPY was €2040.46 (US $2263.24). In the uncontrolled AD group (POEM score ≥8), the mean medication cost PPY was €449.55 (US $498.63), and the mean total direct cost PPY was €1539.39 (US $1707.36)(Table 2). The comparisons of the study groups—controlled vs uncontrolled AD—showed no significant differences regarding medication costs PPY (P=.305, Mann-Whitney U statistic) and total direct costs PPY (P=.361, Mann-Whitney U statistic)(Figure 3). Thus, the distribution of medical costs was similar across all categories of the POEM score.

AD Severity and QOL—The mean (SD) POEM score in the study cohort was 17.9 (6.9). Sixteen (9.6%) patients had clear to almost clear skin or mild AD (POEM score 0–7). Forty-two (25.1%) patients had moderate AD (POEM score 8–16). Most of the patients (106; 63.5%) had severe or very severe AD (POEM score 17–28). According to the Rajka & Langeland score, 5 (3.0%) patients had mild disease (score 34), 81 (48.5%) patients had moderate disease (score 5–7), and 81 (48.5%) patients had severe disease (score 8–9). Eighty-one (48.5%) patients answered that AD affects their lives greatly, and 58 (34.7%) patients answered that it affects their lives extremely. Twenty-five (15.0%) patients answered that AD affects their everyday life to some extent, and only 2 (1.2%) patients answered that AD had little or no effect.

The mean (SD) DLQI was 13 (7.2). Based on the DLQI, 31 (18.6%) patients answered that AD had no effect or only a small effect on QOL (DLQI 0–5). In 36 (21.6%) patients, AD had a moderate effect on QOL (DLQI 6–10). The QOL impact was large (DLQI 11–20) and very large (DLQI 21–30) in 67 (40.1%) and 33 (19.8%) patients, respectively.

There was no significant difference in the impact of disease severity (POEM score) on the decrease of QOL (severe or very severe disease; P=.305, Mann-Whitney U statistic).

Absence From Work or Studies—At the study inclusion, 12 (7.2%) patients were not working or studying. Of the remaining 155 patients, 73 (47.1%) reported absence from work or educational activities due to AD in the last 12 months. The mean (SD) length of absence was 11.6 (10.2) days.

Comment

In this survey-based study of Finnish patients with moderate to severe AD, we observed that AD creates a substantial economic burden¹⁴ and negative impact on everyday life and QOL. According to DLQI, AD had a large or very large effect on most of the patients’ (59.9%) lives, and 90.2% of the included patients had self-reported moderate to very severe symptoms (POEM score 8–28). Our observations can partly be explained by characteristics of the Finnish health care system, in which patients with moderate to severe AD mainly are referred to specialist consultation. In the investigated cohort, many patients had used antibiotics (20.4%) and/or oral corticosteroids (21.6%) in the last year for the treatment of AD, which might indicate inadequate treatment of AD in the Finnish health care system.

Motivating patients to remain compliant is one of the main challenges in AD therapy.¹⁵ Fear of adverse effects from TCSs is common among patients and may cause poor treatment adherence.¹⁶ In a prospective study from the United Kingdom, the use of emollients in moderate to severe AD was considerably lower than AD guidelines recommend—approximately 10 g/d on average in adult patients. The median use of TCSs was between 35 and 38 g/mo.¹⁷ In our Finnish patient cohort, the amount of topical treatments was even lower, with a median use of emollients of 3.3 g/d and median use of TCSs of 25 g/mo. In another study from Denmark (N=322), 31% of patients with AD did not redeem their topical prescription medicaments, indicating poor adherence to topical treatment.¹⁸

It has been demonstrated that most of the patients’ habituation (tachyphylaxis) to TCSs is due to poor adherence instead of physiologic changes in tissue corticosteroid receptors.^19,20 Treatment adherence may be increased by scheduling early follow-up visits and providing adequate therapeutic patient education,²¹ which requires major efforts by the health care system and a financial investment.

Inadequate treatment will lead to more frequent disease flares and subsequently increase the medical costs for the patients and the health care system.²² In our Finnish patient cohort, a large part of direct treatment costs was due to inpatient treatment (Figure 2) even though only a small proportion of patients had been hospitalized. The patients were frequently young and otherwise in good general health, and they did not necessarily need continuous inpatient treatment and monitoring. In Finland, it will be necessary to develop more cost-effective treatment regimens for patients with AD with severe and frequent flares. Many patients would benefit from subsequent and regular sessions of topical treatment in an outpatient setting. In addition, the prevention of flares in moderate to severe AD will decrease medical costs.²³

The mean medication cost PPY was €457.40 (US $507.34), and mean total direct cost PPY was €1579.90 (US $1752.40), which indicates that AD causes a major economic burden to Finnish patients and to the Finnish health care system (Figures 1 and 2).²⁴ We did not observe significant differences between controlled and uncontrolled AD medical costs in our patient cohort (Figure 3), which may have been due to the relatively small sample size of only 16 patients in the controlled AD group. All patients attending the tertiary care hospital had moderate to severe AD, so it is likely that the patients with lower POEM scores had better-controlled disease. The POEM score estimates the grade of AD in the last 7 days, but based on the relapsing course of the disease, the grading score may differ substantially during the year in the same patient depending on the timing.^25,26

Topical calcineurin inhibitors comprised almost half of the medication costs (Figure 1), which may be caused by their higher prices compared with TCSs in Finland. In the beginning of 2019, a 50% less expensive biosimilar of tacrolimus ointment 0.1% was introduced to the Finnish market, which might decrease future treatment costs of TCIs. However, availability problems in both topical tacrolimus products were seen throughout 2019, which also may have affected the results in our study cohort. The median use of TCIs was unexpectedly low (only 30 g/y), which may be explained by different application habits. The use of large TCI amounts in some patients may have elevated mean costs.²⁷

In the Finnish public health care system, 40% of the cost for prescription medication and emollients is reimbursed after an initial deductible of €50. Emollients are reimbursed up to an amount of 1500 g/mo. Therefore, patients mostly acquired emollients as prescription medicine and not over-the-counter. Nonprescription medicaments were not included in our study, so the actual costs of topical treatment may have been higher.²⁸

In our cohort, 61.7% of the patients reported food allergies, and 70.1% reported allergic conjunctivitis. However, the study included only questionnaire-based data, and many of these patients probably had symptoms not associated with IgE-mediated allergies. The high prevalence indicates a substantial concomitant burden of more than skin symptoms in patients with AD.²⁹ Nine percent of patients reported a diagnosed psychiatric disorder, and 29.3% had self-reported anxiety or depression often or very often in the last year. Based on these findings, there may be high percentages of undiagnosed psychiatric comorbidities such as depression and anxiety disorders in patients with moderate to severe AD in Finland.³⁰ An important limitation of our study was that the patient data were based on a voluntary and anonymous survey and that depression and anxiety were addressed solely by a single question. In addition, the response rate cannot be analyzed correctly, and the demographics of the survey responders likely will differ substantially from all patients with AD at the university hospital.

Atopic dermatitis had a substantial effect on QOL in our patient cohort. Inadequate treatment of AD is known to negatively affect patient QOL and may lead to hospitalization or frequent oral corticosteroid courses.^31,32 In most cases, structured patient education and early follow-up visits may improve patient adherence to treatment and should be considered as an integral part of AD treatment.³³ In the investigated Finnish tertiary care hospital, a structured patient education system unfortunately was still lacking, though it has been proven effective elsewhere.³⁴ In addition, patient-centred educational programs are recommended in European guidelines for the treatment of AD.³⁵

Medical costs of AD may increase in the future as new treatments with higher direct costs, such as dupilumab, are introduced. Eichenfeld et al³⁶ analyzed electronic health plan claims in patients with AD with newly introduced systemic therapies and phototherapies after the availability of dupilumab in the United States (March 2017). Mean annualized total cost in all patients was $20,722; the highest in the dupilumab group with $36,505. Compared to our data, the total costs are much higher, but these are likely to rise in Finland in the future if a substantial amount (eg, 1%–5%) of patients will be on advanced therapies, including dupilumab. If advanced therapies will be introduced more broadly in Finland (eg, in the treatment of moderate AD [10%–20% of patients]), they will represent a major direct cost to the health care system. Zimmermann et al³⁷ showed in a cost-utility analysis that dupilumab improves health outcomes but with additional direct costs, and it is likely more cost-effective in patients with severe AD. Conversely, more efficient treatments may improve severe AD, reduce the need for hospitalization and recurrent doctors’ appointments as well as absence from work, and improve patient QOL,³⁸ consequently decreasing indirect medical costs and disease burden. Ariëns et al³⁹ showed in a recent registry-based study that dupilumab treatment induces a notable rise in work productivity and reduction of associated costs in patients with difficult-to-treat AD.

Conclusion

We aimed to analyze the economic burden of AD in Finland before the introduction of dupilumab. It will be interesting to see what the introduction of dupilumab and other novel systemic therapies have on total economic burden and medical costs. Most patients with AD in Finland can achieve disease control with topical treatments, but it is important to efficiently manage the patients who require additional supportive measures and specialist consultations, which may be challenging in the primary health care system because of the relapsing and remitting nature of the disease.

Atopic dermatitis (AD) is a common inflammatory skin disease that may severely decrease quality of life (QOL) and lead to psychiatric comorbidities.^1-3 Prior studies have indicated that AD causes a substantial economic burden, and disease severity has been proportionally linked to medical costs.^4,5 Results of a multicenter cost-of-illness study from Germany estimated that a relapse of AD costs approximately €123 (US $136). The authors calculated the average annual cost of AD per patient to be €1425 (US $1580), whereas it is €956 (US $1060) in moderate disease and €2068 (US $2293) in severe disease (direct and indirect medical costs included).⁶ An observational cohort study from the Netherlands found that total direct cost per patient-year (PPY) was €4401 (US $4879) for patients with controlled AD vs €6993 (US $7756) for patients with uncontrolled AD.⁷

In a retrospective survey-based study, it was estimated that the annual cost of AD in Canada was approximately CAD $1.4 billion. The cost per patient varied from CAD $282 to CAD $1242 depending on disease severity.⁸ In another retrospective cohort study from the Netherlands, the average direct medical cost per patient with AD seeing a general practitioner was US $71 during follow-up in primary care. If the patient needed specialist consultation, the cost increased to an average of US $186.⁹

We aimed to assess the direct and indirect medical costs in adult patients with moderate to severe AD who attended a tertiary health care center in Finland. In addition, we evaluated the impact of AD on QOL in this patient cohort.

Methods

Study Design—Patients with AD who were treated at the Department of Dermatology and Allergology, Helsinki University Hospital, Finland, between February 2018 and December 2019 were randomly selected to participate in our survey study. All participants provided written informed consent. In Finland, patients with mild AD generally are treated in primary health care centers, and only patients with moderate to severe AD are referred to specialists and tertiary care centers. Patients were excluded if they were younger than 18 years, had AD confined to the hands, or reported the presence of other concomitant skin diseases that were being treated with topical or systemic therapies. The protocol for the study was approved by the local ethics committee of the University of Helsinki.

Questionnaire and Analysis of Disease Severity—The survey included the medical history, signs of atopy, former treatment(s) for AD, skin infections, visits to dermatologists or general practitioners, questions on mental health and hospitalization, and absence from work due to AD in the last 12 months. Disease severity was evaluated using the patient-oriented Rajka & Langeland eczema severity score and Patient Oriented Eczema Measure (POEM).^10,11 The impact on QOL was evaluated by the Dermatology Life Quality Index (DLQI).¹²

Medication Costs—The cost of prescription drugs was based on data from the Finnish national electronic prescription center. In Finland, all prescriptions are made electronically in the database. We analyzed all topical medications (eg, topical corticosteroids [TCSs], topical calcineurin inhibitors [TCIs], and emollients) and systemic medicaments (eg, antibiotics, antihistamines, cyclosporine, methotrexate, and corticosteroids) prescribed for the treatment of AD. In Finland, dupilumab was introduced for the treatment of severe AD in early 2019, and patients receiving dupilumab were excluded from the study. Over-the-counter medications were not included. The costs for laboratory testing were estimations based on the standard monitoring protocols of the Helsinki University Hospital. All costs were based on the Finnish price level standard for the year 2019.

Inpatient/Outpatient Visits and Sick Leave Due to AD—The number of inpatient and outpatient visits due to AD in the last 12 months was evaluated. Outpatient specialist consultations or nurse appointments at Helsinki University Hospital were verified from electronic patient records. In addition, inpatient treatment and phototherapy sessions were calculated from the database.

We assessed the number of sick leave days from work or educational activities during the last year. All costs of transportation for doctors’ appointments, laboratory monitoring, and phototherapy treatments were summed together to estimate the total transportation cost. Visits to nurse and inpatient visits were not included in the total transportation cost because patients often were hospitalized directly after consultation visits, and nurse appointments often were combined with inpatient and outpatient visits. To calculate the total transportation cost, we used a rate of €0.43 per kilometer measured from the patients’ home addresses, which was the official compensation rate of the Finnish Tax Administration for 2019.¹³

Statistical Analysis—Statistical analyses were performed using SPSS Statistics 25 (IBM). Descriptive analyses were used to describe baseline characteristics and to evaluate the mean costs of AD. The patients were divided into 2 groups according to POEM: (1) controlled AD (patients with clear skin or only mild AD; POEM score 0–7) and (2) uncontrolled AD (patients with moderate to very severe AD; POEM score 8–28). The Mann-Whitney U statistic was used to evaluate differences between the study groups.

Results

Patient Characteristics—One hundred sixty-seven patients answered the survey, of which 69 (41.3%) were males and 98 (58.7%) were females. There were 16 patients with controlled AD and 148 patients with uncontrolled AD. Three patients did not answer to POEM and were excluded. The baseline characteristics are presented in Table 1 and include self-reported symptoms related to atopy.

The most-used topical treatments were TCSs (n=155; 92.8%) and emollients (n=166; 99.4%). One hundred sixteen (69.5%) patients had used TCIs. The median amount of TCSs used was 300 g/y vs 30 g/y for TCIs (range, 0-5160 g/y) and 1200 g/y for emollients.

Fifteen (9.0%) patients had been hospitalized for AD in the last year. The mean (SD) length of hospitalization was 6.5 (2.8) days. Thirty-four (20.4%) patients received UVB phototherapy. Thirty-four (20.4%) patients were treated with at least 1 antibiotic course for secondary AD infection. Thirty-six (21.6%) patients needed at least 1 oral corticosteroid course for the treatment of an AD flare.

Fifteen (9.0%) patients reported a diagnosed psychiatric illness, and 17 (10.2%) patients were using prescription drugs for psychiatric illness. Forty-nine (29.3%) patients reported anxiety or depression often or very often, 54 (32.3%) patients reported sometimes, 33 (19.8%) patients reported rarely, and only 30 (18.0%) patients reported none.

Medication Costs—Mean medication cost PPY was €457.40 (US $507.34)(Figure 1 and Table 2). On average, one patient spent €87.50 (US $97.05) for TCSs, €121.90 (US $135.21) for emollients, and €225.10 (US $249.68) for TCIs. The average cost PPY for antibiotics was €6.10 (US $6.77). Other systemic treatments, including (US $18.65). Seventeen patients (10.2%) were on methotrexate therapy for AD in the last year, and 1 patient also used cyclosporine. The costs for laboratory monitoring in these patients were included in the direct cost calculations. The mean cost PPY of laboratory monitoring in the whole study cohort was €6.60 (US $7.32). In patients with systemic immunosuppressive therapy, the mean cost PPY for laboratory monitoring was €65.00 (US $72.09). Five patients had been tested for contact dermatitis; the costs of patch tests or other diagnostic tests were not included.

Visits to Health Care Providers—In the last year, patients had an average of 1.83 dermatologist consultations in the tertiary center (Table 2). In addition, the mean number of visits to private dermatologists was 0.61 and 1.42 visits to general practitioners. The mean cost of physician visits was €302.70 (US $335.75) in the tertiary center, €66.60 (US $73.87) in the private sector, and €141.90 (US $157.39) in primary health care. In total, the average cost of doctors’ appointments PPY was €506.30 (US $561.57). The mean estimated distance traveled per visit was 9.5 km.

The mean cost PPY of inpatient treatments was €329.90 (US $365.92) and €239.00 (US $265.09) for UV phototherapy. Only 4 patients had visited a nurse in the last year, with an average cost PPY of €2.50 (US $2.78).

In total, the cost PPY for health care provider visits was €1084.20, which included specialist consultations in a tertiary center and private sector, visits in primary health care, inpatient treatments, UV phototherapy sessions, nurse appointments in a tertiary center, and laboratory monitoring. The average transportation cost PPY was €34.00 (US $37.71). The mean number of visits to health care providers was 8.3 per year. Altogether, the direct cost PPY in the study cohort was €1580.60 (US $1752.39)(Table 2 and Figure 2).

Comparison of Medical Costs in Controlled vs Uncontrolled AD—In the controlled AD group (POEM score <8), the mean medication cost PPY was €567.15 (US $629.13), and the mean total direct cost PPY was €2040.46 (US $2263.24). In the uncontrolled AD group (POEM score ≥8), the mean medication cost PPY was €449.55 (US $498.63), and the mean total direct cost PPY was €1539.39 (US $1707.36)(Table 2). The comparisons of the study groups—controlled vs uncontrolled AD—showed no significant differences regarding medication costs PPY (P=.305, Mann-Whitney U statistic) and total direct costs PPY (P=.361, Mann-Whitney U statistic)(Figure 3). Thus, the distribution of medical costs was similar across all categories of the POEM score.

AD Severity and QOL—The mean (SD) POEM score in the study cohort was 17.9 (6.9). Sixteen (9.6%) patients had clear to almost clear skin or mild AD (POEM score 0–7). Forty-two (25.1%) patients had moderate AD (POEM score 8–16). Most of the patients (106; 63.5%) had severe or very severe AD (POEM score 17–28). According to the Rajka & Langeland score, 5 (3.0%) patients had mild disease (score 34), 81 (48.5%) patients had moderate disease (score 5–7), and 81 (48.5%) patients had severe disease (score 8–9). Eighty-one (48.5%) patients answered that AD affects their lives greatly, and 58 (34.7%) patients answered that it affects their lives extremely. Twenty-five (15.0%) patients answered that AD affects their everyday life to some extent, and only 2 (1.2%) patients answered that AD had little or no effect.

The mean (SD) DLQI was 13 (7.2). Based on the DLQI, 31 (18.6%) patients answered that AD had no effect or only a small effect on QOL (DLQI 0–5). In 36 (21.6%) patients, AD had a moderate effect on QOL (DLQI 6–10). The QOL impact was large (DLQI 11–20) and very large (DLQI 21–30) in 67 (40.1%) and 33 (19.8%) patients, respectively.

There was no significant difference in the impact of disease severity (POEM score) on the decrease of QOL (severe or very severe disease; P=.305, Mann-Whitney U statistic).

Absence From Work or Studies—At the study inclusion, 12 (7.2%) patients were not working or studying. Of the remaining 155 patients, 73 (47.1%) reported absence from work or educational activities due to AD in the last 12 months. The mean (SD) length of absence was 11.6 (10.2) days.

Comment

In this survey-based study of Finnish patients with moderate to severe AD, we observed that AD creates a substantial economic burden¹⁴ and negative impact on everyday life and QOL. According to DLQI, AD had a large or very large effect on most of the patients’ (59.9%) lives, and 90.2% of the included patients had self-reported moderate to very severe symptoms (POEM score 8–28). Our observations can partly be explained by characteristics of the Finnish health care system, in which patients with moderate to severe AD mainly are referred to specialist consultation. In the investigated cohort, many patients had used antibiotics (20.4%) and/or oral corticosteroids (21.6%) in the last year for the treatment of AD, which might indicate inadequate treatment of AD in the Finnish health care system.

Motivating patients to remain compliant is one of the main challenges in AD therapy.¹⁵ Fear of adverse effects from TCSs is common among patients and may cause poor treatment adherence.¹⁶ In a prospective study from the United Kingdom, the use of emollients in moderate to severe AD was considerably lower than AD guidelines recommend—approximately 10 g/d on average in adult patients. The median use of TCSs was between 35 and 38 g/mo.¹⁷ In our Finnish patient cohort, the amount of topical treatments was even lower, with a median use of emollients of 3.3 g/d and median use of TCSs of 25 g/mo. In another study from Denmark (N=322), 31% of patients with AD did not redeem their topical prescription medicaments, indicating poor adherence to topical treatment.¹⁸

It has been demonstrated that most of the patients’ habituation (tachyphylaxis) to TCSs is due to poor adherence instead of physiologic changes in tissue corticosteroid receptors.^19,20 Treatment adherence may be increased by scheduling early follow-up visits and providing adequate therapeutic patient education,²¹ which requires major efforts by the health care system and a financial investment.

Inadequate treatment will lead to more frequent disease flares and subsequently increase the medical costs for the patients and the health care system.²² In our Finnish patient cohort, a large part of direct treatment costs was due to inpatient treatment (Figure 2) even though only a small proportion of patients had been hospitalized. The patients were frequently young and otherwise in good general health, and they did not necessarily need continuous inpatient treatment and monitoring. In Finland, it will be necessary to develop more cost-effective treatment regimens for patients with AD with severe and frequent flares. Many patients would benefit from subsequent and regular sessions of topical treatment in an outpatient setting. In addition, the prevention of flares in moderate to severe AD will decrease medical costs.²³

The mean medication cost PPY was €457.40 (US $507.34), and mean total direct cost PPY was €1579.90 (US $1752.40), which indicates that AD causes a major economic burden to Finnish patients and to the Finnish health care system (Figures 1 and 2).²⁴ We did not observe significant differences between controlled and uncontrolled AD medical costs in our patient cohort (Figure 3), which may have been due to the relatively small sample size of only 16 patients in the controlled AD group. All patients attending the tertiary care hospital had moderate to severe AD, so it is likely that the patients with lower POEM scores had better-controlled disease. The POEM score estimates the grade of AD in the last 7 days, but based on the relapsing course of the disease, the grading score may differ substantially during the year in the same patient depending on the timing.^25,26

Topical calcineurin inhibitors comprised almost half of the medication costs (Figure 1), which may be caused by their higher prices compared with TCSs in Finland. In the beginning of 2019, a 50% less expensive biosimilar of tacrolimus ointment 0.1% was introduced to the Finnish market, which might decrease future treatment costs of TCIs. However, availability problems in both topical tacrolimus products were seen throughout 2019, which also may have affected the results in our study cohort. The median use of TCIs was unexpectedly low (only 30 g/y), which may be explained by different application habits. The use of large TCI amounts in some patients may have elevated mean costs.²⁷

In the Finnish public health care system, 40% of the cost for prescription medication and emollients is reimbursed after an initial deductible of €50. Emollients are reimbursed up to an amount of 1500 g/mo. Therefore, patients mostly acquired emollients as prescription medicine and not over-the-counter. Nonprescription medicaments were not included in our study, so the actual costs of topical treatment may have been higher.²⁸

In our cohort, 61.7% of the patients reported food allergies, and 70.1% reported allergic conjunctivitis. However, the study included only questionnaire-based data, and many of these patients probably had symptoms not associated with IgE-mediated allergies. The high prevalence indicates a substantial concomitant burden of more than skin symptoms in patients with AD.²⁹ Nine percent of patients reported a diagnosed psychiatric disorder, and 29.3% had self-reported anxiety or depression often or very often in the last year. Based on these findings, there may be high percentages of undiagnosed psychiatric comorbidities such as depression and anxiety disorders in patients with moderate to severe AD in Finland.³⁰ An important limitation of our study was that the patient data were based on a voluntary and anonymous survey and that depression and anxiety were addressed solely by a single question. In addition, the response rate cannot be analyzed correctly, and the demographics of the survey responders likely will differ substantially from all patients with AD at the university hospital.

Atopic dermatitis had a substantial effect on QOL in our patient cohort. Inadequate treatment of AD is known to negatively affect patient QOL and may lead to hospitalization or frequent oral corticosteroid courses.^31,32 In most cases, structured patient education and early follow-up visits may improve patient adherence to treatment and should be considered as an integral part of AD treatment.³³ In the investigated Finnish tertiary care hospital, a structured patient education system unfortunately was still lacking, though it has been proven effective elsewhere.³⁴ In addition, patient-centred educational programs are recommended in European guidelines for the treatment of AD.³⁵

Medical costs of AD may increase in the future as new treatments with higher direct costs, such as dupilumab, are introduced. Eichenfeld et al³⁶ analyzed electronic health plan claims in patients with AD with newly introduced systemic therapies and phototherapies after the availability of dupilumab in the United States (March 2017). Mean annualized total cost in all patients was $20,722; the highest in the dupilumab group with $36,505. Compared to our data, the total costs are much higher, but these are likely to rise in Finland in the future if a substantial amount (eg, 1%–5%) of patients will be on advanced therapies, including dupilumab. If advanced therapies will be introduced more broadly in Finland (eg, in the treatment of moderate AD [10%–20% of patients]), they will represent a major direct cost to the health care system. Zimmermann et al³⁷ showed in a cost-utility analysis that dupilumab improves health outcomes but with additional direct costs, and it is likely more cost-effective in patients with severe AD. Conversely, more efficient treatments may improve severe AD, reduce the need for hospitalization and recurrent doctors’ appointments as well as absence from work, and improve patient QOL,³⁸ consequently decreasing indirect medical costs and disease burden. Ariëns et al³⁹ showed in a recent registry-based study that dupilumab treatment induces a notable rise in work productivity and reduction of associated costs in patients with difficult-to-treat AD.

Conclusion

We aimed to analyze the economic burden of AD in Finland before the introduction of dupilumab. It will be interesting to see what the introduction of dupilumab and other novel systemic therapies have on total economic burden and medical costs. Most patients with AD in Finland can achieve disease control with topical treatments, but it is important to efficiently manage the patients who require additional supportive measures and specialist consultations, which may be challenging in the primary health care system because of the relapsing and remitting nature of the disease.

Atopic dermatitis (AD) is a common inflammatory skin disease that may severely decrease quality of life (QOL) and lead to psychiatric comorbidities.^1-3 Prior studies have indicated that AD causes a substantial economic burden, and disease severity has been proportionally linked to medical costs.^4,5 Results of a multicenter cost-of-illness study from Germany estimated that a relapse of AD costs approximately €123 (US $136). The authors calculated the average annual cost of AD per patient to be €1425 (US $1580), whereas it is €956 (US $1060) in moderate disease and €2068 (US $2293) in severe disease (direct and indirect medical costs included).⁶ An observational cohort study from the Netherlands found that total direct cost per patient-year (PPY) was €4401 (US $4879) for patients with controlled AD vs €6993 (US $7756) for patients with uncontrolled AD.⁷

In a retrospective survey-based study, it was estimated that the annual cost of AD in Canada was approximately CAD $1.4 billion. The cost per patient varied from CAD $282 to CAD $1242 depending on disease severity.⁸ In another retrospective cohort study from the Netherlands, the average direct medical cost per patient with AD seeing a general practitioner was US $71 during follow-up in primary care. If the patient needed specialist consultation, the cost increased to an average of US $186.⁹

We aimed to assess the direct and indirect medical costs in adult patients with moderate to severe AD who attended a tertiary health care center in Finland. In addition, we evaluated the impact of AD on QOL in this patient cohort.

Methods

Study Design—Patients with AD who were treated at the Department of Dermatology and Allergology, Helsinki University Hospital, Finland, between February 2018 and December 2019 were randomly selected to participate in our survey study. All participants provided written informed consent. In Finland, patients with mild AD generally are treated in primary health care centers, and only patients with moderate to severe AD are referred to specialists and tertiary care centers. Patients were excluded if they were younger than 18 years, had AD confined to the hands, or reported the presence of other concomitant skin diseases that were being treated with topical or systemic therapies. The protocol for the study was approved by the local ethics committee of the University of Helsinki.

Questionnaire and Analysis of Disease Severity—The survey included the medical history, signs of atopy, former treatment(s) for AD, skin infections, visits to dermatologists or general practitioners, questions on mental health and hospitalization, and absence from work due to AD in the last 12 months. Disease severity was evaluated using the patient-oriented Rajka & Langeland eczema severity score and Patient Oriented Eczema Measure (POEM).^10,11 The impact on QOL was evaluated by the Dermatology Life Quality Index (DLQI).¹²

Medication Costs—The cost of prescription drugs was based on data from the Finnish national electronic prescription center. In Finland, all prescriptions are made electronically in the database. We analyzed all topical medications (eg, topical corticosteroids [TCSs], topical calcineurin inhibitors [TCIs], and emollients) and systemic medicaments (eg, antibiotics, antihistamines, cyclosporine, methotrexate, and corticosteroids) prescribed for the treatment of AD. In Finland, dupilumab was introduced for the treatment of severe AD in early 2019, and patients receiving dupilumab were excluded from the study. Over-the-counter medications were not included. The costs for laboratory testing were estimations based on the standard monitoring protocols of the Helsinki University Hospital. All costs were based on the Finnish price level standard for the year 2019.

Inpatient/Outpatient Visits and Sick Leave Due to AD—The number of inpatient and outpatient visits due to AD in the last 12 months was evaluated. Outpatient specialist consultations or nurse appointments at Helsinki University Hospital were verified from electronic patient records. In addition, inpatient treatment and phototherapy sessions were calculated from the database.

We assessed the number of sick leave days from work or educational activities during the last year. All costs of transportation for doctors’ appointments, laboratory monitoring, and phototherapy treatments were summed together to estimate the total transportation cost. Visits to nurse and inpatient visits were not included in the total transportation cost because patients often were hospitalized directly after consultation visits, and nurse appointments often were combined with inpatient and outpatient visits. To calculate the total transportation cost, we used a rate of €0.43 per kilometer measured from the patients’ home addresses, which was the official compensation rate of the Finnish Tax Administration for 2019.¹³

Statistical Analysis—Statistical analyses were performed using SPSS Statistics 25 (IBM). Descriptive analyses were used to describe baseline characteristics and to evaluate the mean costs of AD. The patients were divided into 2 groups according to POEM: (1) controlled AD (patients with clear skin or only mild AD; POEM score 0–7) and (2) uncontrolled AD (patients with moderate to very severe AD; POEM score 8–28). The Mann-Whitney U statistic was used to evaluate differences between the study groups.

Results

Patient Characteristics—One hundred sixty-seven patients answered the survey, of which 69 (41.3%) were males and 98 (58.7%) were females. There were 16 patients with controlled AD and 148 patients with uncontrolled AD. Three patients did not answer to POEM and were excluded. The baseline characteristics are presented in Table 1 and include self-reported symptoms related to atopy.

The most-used topical treatments were TCSs (n=155; 92.8%) and emollients (n=166; 99.4%). One hundred sixteen (69.5%) patients had used TCIs. The median amount of TCSs used was 300 g/y vs 30 g/y for TCIs (range, 0-5160 g/y) and 1200 g/y for emollients.

Fifteen (9.0%) patients had been hospitalized for AD in the last year. The mean (SD) length of hospitalization was 6.5 (2.8) days. Thirty-four (20.4%) patients received UVB phototherapy. Thirty-four (20.4%) patients were treated with at least 1 antibiotic course for secondary AD infection. Thirty-six (21.6%) patients needed at least 1 oral corticosteroid course for the treatment of an AD flare.

Fifteen (9.0%) patients reported a diagnosed psychiatric illness, and 17 (10.2%) patients were using prescription drugs for psychiatric illness. Forty-nine (29.3%) patients reported anxiety or depression often or very often, 54 (32.3%) patients reported sometimes, 33 (19.8%) patients reported rarely, and only 30 (18.0%) patients reported none.

Medication Costs—Mean medication cost PPY was €457.40 (US $507.34)(Figure 1 and Table 2). On average, one patient spent €87.50 (US $97.05) for TCSs, €121.90 (US $135.21) for emollients, and €225.10 (US $249.68) for TCIs. The average cost PPY for antibiotics was €6.10 (US $6.77). Other systemic treatments, including (US $18.65). Seventeen patients (10.2%) were on methotrexate therapy for AD in the last year, and 1 patient also used cyclosporine. The costs for laboratory monitoring in these patients were included in the direct cost calculations. The mean cost PPY of laboratory monitoring in the whole study cohort was €6.60 (US $7.32). In patients with systemic immunosuppressive therapy, the mean cost PPY for laboratory monitoring was €65.00 (US $72.09). Five patients had been tested for contact dermatitis; the costs of patch tests or other diagnostic tests were not included.

Visits to Health Care Providers—In the last year, patients had an average of 1.83 dermatologist consultations in the tertiary center (Table 2). In addition, the mean number of visits to private dermatologists was 0.61 and 1.42 visits to general practitioners. The mean cost of physician visits was €302.70 (US $335.75) in the tertiary center, €66.60 (US $73.87) in the private sector, and €141.90 (US $157.39) in primary health care. In total, the average cost of doctors’ appointments PPY was €506.30 (US $561.57). The mean estimated distance traveled per visit was 9.5 km.

The mean cost PPY of inpatient treatments was €329.90 (US $365.92) and €239.00 (US $265.09) for UV phototherapy. Only 4 patients had visited a nurse in the last year, with an average cost PPY of €2.50 (US $2.78).

In total, the cost PPY for health care provider visits was €1084.20, which included specialist consultations in a tertiary center and private sector, visits in primary health care, inpatient treatments, UV phototherapy sessions, nurse appointments in a tertiary center, and laboratory monitoring. The average transportation cost PPY was €34.00 (US $37.71). The mean number of visits to health care providers was 8.3 per year. Altogether, the direct cost PPY in the study cohort was €1580.60 (US $1752.39)(Table 2 and Figure 2).

Comparison of Medical Costs in Controlled vs Uncontrolled AD—In the controlled AD group (POEM score <8), the mean medication cost PPY was €567.15 (US $629.13), and the mean total direct cost PPY was €2040.46 (US $2263.24). In the uncontrolled AD group (POEM score ≥8), the mean medication cost PPY was €449.55 (US $498.63), and the mean total direct cost PPY was €1539.39 (US $1707.36)(Table 2). The comparisons of the study groups—controlled vs uncontrolled AD—showed no significant differences regarding medication costs PPY (P=.305, Mann-Whitney U statistic) and total direct costs PPY (P=.361, Mann-Whitney U statistic)(Figure 3). Thus, the distribution of medical costs was similar across all categories of the POEM score.

AD Severity and QOL—The mean (SD) POEM score in the study cohort was 17.9 (6.9). Sixteen (9.6%) patients had clear to almost clear skin or mild AD (POEM score 0–7). Forty-two (25.1%) patients had moderate AD (POEM score 8–16). Most of the patients (106; 63.5%) had severe or very severe AD (POEM score 17–28). According to the Rajka & Langeland score, 5 (3.0%) patients had mild disease (score 34), 81 (48.5%) patients had moderate disease (score 5–7), and 81 (48.5%) patients had severe disease (score 8–9). Eighty-one (48.5%) patients answered that AD affects their lives greatly, and 58 (34.7%) patients answered that it affects their lives extremely. Twenty-five (15.0%) patients answered that AD affects their everyday life to some extent, and only 2 (1.2%) patients answered that AD had little or no effect.

The mean (SD) DLQI was 13 (7.2). Based on the DLQI, 31 (18.6%) patients answered that AD had no effect or only a small effect on QOL (DLQI 0–5). In 36 (21.6%) patients, AD had a moderate effect on QOL (DLQI 6–10). The QOL impact was large (DLQI 11–20) and very large (DLQI 21–30) in 67 (40.1%) and 33 (19.8%) patients, respectively.

There was no significant difference in the impact of disease severity (POEM score) on the decrease of QOL (severe or very severe disease; P=.305, Mann-Whitney U statistic).

Absence From Work or Studies—At the study inclusion, 12 (7.2%) patients were not working or studying. Of the remaining 155 patients, 73 (47.1%) reported absence from work or educational activities due to AD in the last 12 months. The mean (SD) length of absence was 11.6 (10.2) days.

Comment

In this survey-based study of Finnish patients with moderate to severe AD, we observed that AD creates a substantial economic burden¹⁴ and negative impact on everyday life and QOL. According to DLQI, AD had a large or very large effect on most of the patients’ (59.9%) lives, and 90.2% of the included patients had self-reported moderate to very severe symptoms (POEM score 8–28). Our observations can partly be explained by characteristics of the Finnish health care system, in which patients with moderate to severe AD mainly are referred to specialist consultation. In the investigated cohort, many patients had used antibiotics (20.4%) and/or oral corticosteroids (21.6%) in the last year for the treatment of AD, which might indicate inadequate treatment of AD in the Finnish health care system.

Motivating patients to remain compliant is one of the main challenges in AD therapy.¹⁵ Fear of adverse effects from TCSs is common among patients and may cause poor treatment adherence.¹⁶ In a prospective study from the United Kingdom, the use of emollients in moderate to severe AD was considerably lower than AD guidelines recommend—approximately 10 g/d on average in adult patients. The median use of TCSs was between 35 and 38 g/mo.¹⁷ In our Finnish patient cohort, the amount of topical treatments was even lower, with a median use of emollients of 3.3 g/d and median use of TCSs of 25 g/mo. In another study from Denmark (N=322), 31% of patients with AD did not redeem their topical prescription medicaments, indicating poor adherence to topical treatment.¹⁸

It has been demonstrated that most of the patients’ habituation (tachyphylaxis) to TCSs is due to poor adherence instead of physiologic changes in tissue corticosteroid receptors.^19,20 Treatment adherence may be increased by scheduling early follow-up visits and providing adequate therapeutic patient education,²¹ which requires major efforts by the health care system and a financial investment.

Inadequate treatment will lead to more frequent disease flares and subsequently increase the medical costs for the patients and the health care system.²² In our Finnish patient cohort, a large part of direct treatment costs was due to inpatient treatment (Figure 2) even though only a small proportion of patients had been hospitalized. The patients were frequently young and otherwise in good general health, and they did not necessarily need continuous inpatient treatment and monitoring. In Finland, it will be necessary to develop more cost-effective treatment regimens for patients with AD with severe and frequent flares. Many patients would benefit from subsequent and regular sessions of topical treatment in an outpatient setting. In addition, the prevention of flares in moderate to severe AD will decrease medical costs.²³

The mean medication cost PPY was €457.40 (US $507.34), and mean total direct cost PPY was €1579.90 (US $1752.40), which indicates that AD causes a major economic burden to Finnish patients and to the Finnish health care system (Figures 1 and 2).²⁴ We did not observe significant differences between controlled and uncontrolled AD medical costs in our patient cohort (Figure 3), which may have been due to the relatively small sample size of only 16 patients in the controlled AD group. All patients attending the tertiary care hospital had moderate to severe AD, so it is likely that the patients with lower POEM scores had better-controlled disease. The POEM score estimates the grade of AD in the last 7 days, but based on the relapsing course of the disease, the grading score may differ substantially during the year in the same patient depending on the timing.^25,26

Topical calcineurin inhibitors comprised almost half of the medication costs (Figure 1), which may be caused by their higher prices compared with TCSs in Finland. In the beginning of 2019, a 50% less expensive biosimilar of tacrolimus ointment 0.1% was introduced to the Finnish market, which might decrease future treatment costs of TCIs. However, availability problems in both topical tacrolimus products were seen throughout 2019, which also may have affected the results in our study cohort. The median use of TCIs was unexpectedly low (only 30 g/y), which may be explained by different application habits. The use of large TCI amounts in some patients may have elevated mean costs.²⁷

In the Finnish public health care system, 40% of the cost for prescription medication and emollients is reimbursed after an initial deductible of €50. Emollients are reimbursed up to an amount of 1500 g/mo. Therefore, patients mostly acquired emollients as prescription medicine and not over-the-counter. Nonprescription medicaments were not included in our study, so the actual costs of topical treatment may have been higher.²⁸

In our cohort, 61.7% of the patients reported food allergies, and 70.1% reported allergic conjunctivitis. However, the study included only questionnaire-based data, and many of these patients probably had symptoms not associated with IgE-mediated allergies. The high prevalence indicates a substantial concomitant burden of more than skin symptoms in patients with AD.²⁹ Nine percent of patients reported a diagnosed psychiatric disorder, and 29.3% had self-reported anxiety or depression often or very often in the last year. Based on these findings, there may be high percentages of undiagnosed psychiatric comorbidities such as depression and anxiety disorders in patients with moderate to severe AD in Finland.³⁰ An important limitation of our study was that the patient data were based on a voluntary and anonymous survey and that depression and anxiety were addressed solely by a single question. In addition, the response rate cannot be analyzed correctly, and the demographics of the survey responders likely will differ substantially from all patients with AD at the university hospital.

Atopic dermatitis had a substantial effect on QOL in our patient cohort. Inadequate treatment of AD is known to negatively affect patient QOL and may lead to hospitalization or frequent oral corticosteroid courses.^31,32 In most cases, structured patient education and early follow-up visits may improve patient adherence to treatment and should be considered as an integral part of AD treatment.³³ In the investigated Finnish tertiary care hospital, a structured patient education system unfortunately was still lacking, though it has been proven effective elsewhere.³⁴ In addition, patient-centred educational programs are recommended in European guidelines for the treatment of AD.³⁵

Medical costs of AD may increase in the future as new treatments with higher direct costs, such as dupilumab, are introduced. Eichenfeld et al³⁶ analyzed electronic health plan claims in patients with AD with newly introduced systemic therapies and phototherapies after the availability of dupilumab in the United States (March 2017). Mean annualized total cost in all patients was $20,722; the highest in the dupilumab group with $36,505. Compared to our data, the total costs are much higher, but these are likely to rise in Finland in the future if a substantial amount (eg, 1%–5%) of patients will be on advanced therapies, including dupilumab. If advanced therapies will be introduced more broadly in Finland (eg, in the treatment of moderate AD [10%–20% of patients]), they will represent a major direct cost to the health care system. Zimmermann et al³⁷ showed in a cost-utility analysis that dupilumab improves health outcomes but with additional direct costs, and it is likely more cost-effective in patients with severe AD. Conversely, more efficient treatments may improve severe AD, reduce the need for hospitalization and recurrent doctors’ appointments as well as absence from work, and improve patient QOL,³⁸ consequently decreasing indirect medical costs and disease burden. Ariëns et al³⁹ showed in a recent registry-based study that dupilumab treatment induces a notable rise in work productivity and reduction of associated costs in patients with difficult-to-treat AD.

Conclusion

We aimed to analyze the economic burden of AD in Finland before the introduction of dupilumab. It will be interesting to see what the introduction of dupilumab and other novel systemic therapies have on total economic burden and medical costs. Most patients with AD in Finland can achieve disease control with topical treatments, but it is important to efficiently manage the patients who require additional supportive measures and specialist consultations, which may be challenging in the primary health care system because of the relapsing and remitting nature of the disease.

A teledermatology clinic program established in Ward 8 of Washington, D.C., to help residents learn about and initiate care for atopic dermatitis (AD) has garnered high patient satisfaction marks and may serve as a model for similar clinics in other underserved areas in the United States.

Washington, D.C., has “staggering health disparities that are among the largest in the country,” and Ward 8 and surrounding areas in the southeastern part of the city are “dermatology deserts,” said Adam Friedman, MD, professor and chair of dermatology at George Washington University, Washington, who started the program in 2021 with a pilot project. Dr. Friedman spoke about the project, which has since been expanded to include alopecia areata, at the Revolutionizing Atopic Dermatitis conference in April and in an interview after the meeting.

Patients who attend the clinics – held at the Temple of Praise Church in a residential area of Ward 8, a predominantly Black community with a 30% poverty rate – are entered into the GW Medical Faculty Associates medical records system and educated on telemedicine best practices (such as not having light behind them during a session) and how to use telemedicine with their own device.

Those with AD who participate learn about the condition through an image-rich poster showing how it appears in various skin tones, handouts, National Eczema Association films, and discussion with medical students who staff the clinics under Dr. Friedman’s on-site supervision. Participants with alopecia areata similarly can view a poster and converse about the condition.

Patients then have a free 20-minute telehealth visit with a GWU dermatology resident in a private room, and a medical student volunteer nearby to assist with the technology if needed. They leave with a treatment plan, which often includes prescriptions, and a follow-up telemedicine appointment.

The program “is meant to be a stepping point for initiating care ... to set someone up for success for recurrent telehealth visits in the future” and for treatment before symptoms become too severe, Dr. Friedman said in an interview. “We want to demystify telemedicine and educate on the disease state and dispel myths ... so the patient understands why it’s happening” and how it can be treated.

Dr. Adam Friedman

The pilot project, funded with a grant from Pfizer, involved five 2-hour clinics held on Mondays from 4 p.m. to 6 p.m., that together served almost 50 adult and pediatric patients. Grants from Pfizer and Eli Lilly enabled additional clinics in the spring of 2023 and into the summer. And in June, GWU and Pfizer announced a $1 million national grant program focused on broad implementation of what they’ve coined the “Teledermatology Help Desk Clinic” model.

Practices or organizations that secure grants will utilize GWU’s experience and meet with an advisory council of experts in dermatology telemedicine and community advocacy. Having a “long-term plan” and commitment to sustainability is an important element of the model, said Dr. Friedman, who is chairing the grant program.


 

Patients deem clinic ‘extremely’ helpful

As one of the most prevalent skin disorders – and one with a documented history of elevated risk for specific populations – AD was a good starting point for the teledermatology clinic program. Patients who identify as Black have a higher incidence and prevalence of AD than those who identify as White and Hispanic, and they tend to have more severe disease. Yet they account for fewer visits to dermatologists for AD.

One cross-sectional study of about 3,500 adults in the United States with AD documented that racial/ethnic and socioeconomic disparities reduce outpatient utilization of AD care and increase urgent care and hospital utilization. And in a longitudinal cohort study of children in the United States with AD, Black children with poorly controlled AD were significantly less likely than White children to see a dermatologist.

Dr. Adam Friedman

Like other programs, the GWU department of dermatology had pivoted to telehealth in 2020, and a published survey of patients who attended telehealth appointments during the early part of the pandemic showed that it was generally well liked – and not only for social distancing, but for time efficiency and because transportation was not needed. Only 10% of the 168 patients who completed the survey (out of 894 asked) reported they were unlikely to undertake another telehealth visit. For 10%, eczema was the reason for the visit.

However, only 1% of the survey respondents were from Ward 8, which “begged the question, did those who really need access know this was an option?” Dr. Friedman said at the RAD meeting. He wondered whether there was not only a dermatology desert in Ward 8, but a “technology desert” as well.

Findings from a patient satisfaction survey taken at the end of the pilot program are encouraging, Dr. Friedman said. While data on follow-up visits has not been collected yet, “what I do now have a sense of” is that “the entry point [afforded by the clinics] changed the course in terms of patients’ understanding of the disease and how they feel about its management.”

Dr. Adam Friedman

About 94% of survey respondents indicated the clinic was “extremely” helpful and the remainder said it was “very” helpful; 90% said telehealth significantly changed how they will manage their condition; and 97% said it is “extremely” important to continue the clinics. The majority of patients – 70% – indicated they did not have a dermatologist.

Education about AD at the clinics covers moisturizers/emollients, bathing habits, soaps and detergents, trigger avoidance, and the role of stress and environmental factors in disease exacerbation. Trade samples of moisturizers, mild cleansers, and other products have increasingly been available.

For prescriptions of topical steroids and other commonly prescribed medications, Dr. Friedman and associates combed GoodRx for coupons and surveyed local pharmacies for self-pay pricing to identify least expensive options. Patients with AD who were deemed likely candidates for more advanced therapies in the future were educated about these possibilities.
 

Alopecia areata

The addition of alopecia areata drew patients with other forms of hair loss as well, but “we weren’t going to turn anyone away who did not have that specific autoimmune form of hair loss,” Dr. Friedman said. Depending on the diagnosis, prescriptions were written for minoxidil and 5-alpha reductase inhibitors.

Important for follow-up is GWU’s acceptance of Medicaid and the availability of both a sliding scale for self-pay and services that assist patients in registering for Medicaid and, if eligible, other insurance plans.
 

Building partnerships, earning trust

Establishment of the teledermatology clinic program took legwork and relationship building. “You can’t just show up. That’s not enough,” said Dr. Friedman, who also directs the dermatology residency program at GWU. “You have to show through action and through investment of time and energy that you are legitimate, that you’re really there for the long haul.”

Dr. Adam Friedman

Dr. Friedman had assistance from the Rodham Institute, which was established at GWU (and until recently was housed there) and has a history of engagement with local stakeholders such as community centers, church leadership, politicians, and others in the Washington area. He was put in touch with Bishop Deborah Webb at the Temple of Praise Church, a community pillar in Ward 8, and from there “it was a courtship,” he said, with trust to be built and logistics to be worked out. (Budgets for the clinics, he noted, have included compensation to the church and gift cards for church volunteers who are present at the clinics.)

In the meantime, medical student volunteers from GWU, Howard University, and Georgetown University were trained in telemedicine and attended a “boot camp” on AD “so they’d be able to talk with anyone about it,” Dr. Friedman said.

Advertising “was a learning experience,” he said, and was ultimately multipronged, involving church service announcements, flyers, and, most importantly, Facebook and Instagram advertisements. (People were asked to call a dedicated phone line to schedule an appointment and were invited to register in the GW Medical Faculty Associates records system, though walk-ins to the clinics were still welcomed.)

In a comment, Misty Eleryan, MD, MS, a Mohs micrographic surgeon and dermatologist in Santa Monica, Calif., said dermatology deserts are often found in rural areas and/or areas “with a higher population of marginalized communities, such as Black, Brown, or poorer individuals” – communities that tend to rely on care from urgent care or ED physicians who are unaware of how skin conditions present on darker skin tones.

Programs that educate patients about various presentations of skin conditions are helpful not only for the patients themselves, but could also enable them to help friends, family members, and colleagues, said Dr. Eleryan, who did her residency training at GWU.

“Access,” she noted, is more than just physical access to a person, place, or thing. Referring to a “five A’s” framework described several decades ago, Dr. Eleryan said access to care is characterized by affordability, availability (extent to which the physician has the requisite resources, such as personnel and technology, to meet the patient’s needs), accessibility (geographic), accommodation (extent to which the physician can meet the patient’s constraints and preferences – such as hours of operation, how communications are handled, ability to receive care without prior appointments), and acceptability (extent to which the patient is comfortable with the “more immutable characteristics” of the physician and vice versa).

The GWU program, she said, “is a great start.”

Dr. Friedman said he’s fully invested. There has long been a perception, “rightfully so, that underserved communities are overlooked especially by large institutions. One attendee told me she never expected in her lifetime to see something like this clinic and someone who looked like me caring about her community. ... It certainly says a great deal about the work we need to put in to repair longstanding injury.”

Dr. Friedman disclosed that, in addition to being a recipient of grants from Pfizer and Lilly, he is a speaker for Lilly. Dr. Eleryan said she has no relevant disclosures.

He was put in touch with Bishop Deborah Webb at the Temple of Praise Church, a community pillar in Ward 8, and from there “it was a courtship,” he said, with trust to be built and logistics to be worked out. (Budgets for the clinics, he noted, have included compensation to the church and gift cards for church volunteers who are present at the clinics.)

In the meantime, medical student volunteers from GWU, Howard University, and Georgetown University were trained in telemedicine and attended a “boot camp” on AD “so they’d be able to talk with anyone about it,” Dr. Friedman said.

Advertising “was a learning experience,” he said, and was ultimately multipronged, involving church service announcements, flyers, and, most importantly, Facebook and Instagram advertisements. (People were asked to call a dedicated phone line to schedule an appointment and were invited to register in the GW Medical Faculty Associates records system, though walk-ins to the clinics were still welcomed.)

In a comment, Misty Eleryan, MD, MS, a Mohs micrographic surgeon and dermatologist in Santa Monica, Calif., said dermatology deserts are often found in rural areas and/or areas “with a higher population of marginalized communities, such as Black, Brown, or poorer individuals” – communities that tend to rely on care from urgent care or ED physicians who are unaware of how skin conditions present on darker skin tones.

Programs that educate patients about various presentations of skin conditions are helpful not only for the patients themselves, but could also enable them to help friends, family members, and colleagues, said Dr. Eleryan, who did her residency training at GWU.

“Access,” she noted, is more than just physical access to a person, place, or thing. Referring to a “five A’s” framework described several decades ago, Dr. Eleryan said access to care is characterized by affordability, availability (extent to which the physician has the requisite resources, such as personnel and technology, to meet the patient’s needs), accessibility (geographic), accommodation (extent to which the physician can meet the patient’s constraints and preferences – such as hours of operation, how communications are handled, ability to receive care without prior appointments), and acceptability (extent to which the patient is comfortable with the “more immutable characteristics” of the physician and vice versa).

The GWU program, she said, “is a great start.”

Dr. Friedman said he’s fully invested. There has long been a perception, “rightfully so, that underserved communities are overlooked especially by large institutions. One attendee told me she never expected in her lifetime to see something like this clinic and someone who looked like me caring about her community. ... It certainly says a great deal about the work we need to put in to repair longstanding injury.”

Dr. Friedman disclosed that, in addition to being a recipient of grants from Pfizer and Lilly, he is a speaker for Lilly. Dr. Eleryan said she has no relevant disclosures.

The excellent short-term efficacy of the drug was well maintained up to 48 weeks, with only a slight loss of efficacy over time. Abrocitinib is a small molecule. We wouldn't expect a loss of efficacy due to the anti-drug antibodies that we see for large-molecule biologic drugs. I suspect that the slight loss of efficacy over time is a form of tachyphylaxis that is, to my thinking, probably due to poor adherence. Shocking, I know! Patients may not be fully adherent to treatment, even in a clinical trial. I think we should encourage patients to use 7-day pill boxes to aid better long-term adherence and outcomes.

Long-term safety is a critical issue with any new drug, certainly with a Janus kinase (JAK) inhibitor. Reich and colleagues concluded, "The long-term safety profile was manageable and consistent with previous reports." That conclusion seems reasonable to me. The most common side effects were upper respiratory tract infections. There may be a slight signal for increased risk for oral herpes infection, particularly at the higher dose. If this safety profile endures with longer-term data in larger numbers of people, it will be very reassuring.

The study by Wan and colleagues is another extremely well-done, important study by the premier dermatoepidemiology research team at the University of Pennsylvania. The study used an outstanding database from the United Kingdom that encompassed the clinical care experience of hundreds of thousands of children and adults with atopic dermatitis and millions of control patients without atopic dermatitis. With this many patients, the study has tremendous power to detect risk differences between groups.

With all that power, this study’s findings are very reassuring that there is no meaningful overall increased risk for malignancy in children or adults with atopic dermatitis. And while there was a statistically significant increased risk for lymphoma in children with severe atopic dermatitis, that risk is small … very small. Similarly, adults with severe AD had a twofold higher risk for noncutaneous T-cell lymphoma (CTCL), but since non-CTCL is rare, patients with severe AD shouldn't lose any sleep over it..

Simpson and colleagues' study of the effect of dupilumab on Staphylococcus aureus surprised me. Of course, we could expect that S aureus counts would be reduced with dupilumab; as barrier function is restored, surely S aureus counts would go down too. But, fascinatingly, with dupilumab treatment, S aureus counts decreased almost immediately, at both 3 and 7 days, before there was apparent clinical improvement in the skin rash. Simpson and colleagues suggest that the drop in S aureus counts could be due to improvement in immune function when interleukins 4 and 13 are blocked. Whether or not that is true, it is striking how fast S aureus counts improved, long before normal skin barrier function is restored.

Here's a fun fact: Atopic dermatitis is a little less common, about 10% less common, in people born second or later in the birth order. Lisik and colleagues did a meta-analysis of 114 studies and found this marginally lower rate in those born second or later compared with those born first. I'm not sure that there is any clinically meaningful significance to this, but I found it interesting (even though I was born first, and my younger brother had atopic dermatitis).

Key clinical point: Having siblings and being born second or later is associated with a marginally reduced lifetime risk of developing atopic dermatitis (AD).

Major finding: Children born in the birth order ≥2 vs 1 had a 9% lower risk for ever AD (pooled risk ratio [RR] 0.91; 95% CI 0.84-0.98), and a sibship size ≥2 vs 1 was associated with an 8% lower risk for ever AD (RR 0.92; 95% CI 0.86-0.97) and a 10% lower risk for current AD (RR 0.90; 95% CI 0.83-0.98).

Study details: Findings are from a meta-analysis of 102 observational studies that analyzed the association between birth order or sibship size and the risk for AD.

Key clinical point: Probiotic intake by breastfeeding mothers reduced atopic dermatitis (AD) incidence in children by half, whereas in children receiving probiotic supplementation, AD incidence decreased by 22% only.

Major finding: Probiotic intake by pregnant and breastfeeding mothers, pregnant and breastfeeding mothers and children, and pregnant mothers and children reduced the incidence of pediatric AD by 49% (relative risk [RR] 0.51; 95% CI 0.39-0.66), 39% (RR 0.61; 95% CI 0.43-0.86), and 27% (RR 0.73; 95% CI 0.63-0.86), respectively. Children receiving probiotics vs placebo had a 22% lower incidence of AD (RR 0.78; 95% CI 0.64-0.94).

Study details: Findings are from a systematic review and meta-analysis of 75 studies on the prophylactic (n = 8754 participants) or therapeutic (n = 2021 children) effects of probiotics in children age ≤ 18 years, including 17 studies involving 2844 children who received probiotics or placebo.

Key clinical point: A history of herpes zoster (HZ) infection is a predictive factor for the occurrence of HZ in patients with moderate-to-severe atopic dermatitis (AD) during upadacitinib therapy.

Major finding: The incidence of a history of HZ was significantly higher in patients with vs without the occurrence of HZ in the 15 mg upadacitinib (70% vs 3%), 30 mg upadacitinib (100% vs 10%), and overall (79% vs 5%) groups (all P < .01). HZ history was significantly associated with the occurrence of HZ during treatment in the 15 mg upadacitinib (adjusted odds ratio [aOR] 172) and overall (aOR 74.6) groups (both P < .01).

Study details: Findings are from a retrospective analysis of 112 patients aged ≥12 years with moderate-to-severe AD who received 15 mg upadacitinib (n = 78) or 30 mg upadacitinib (n = 34) daily for 3-9 months.

Disclosures: This study did not declare the funding source. All authors, except E Fujimoto, declared receiving research funding or lecture fees from AbbVie GK.
