Determinants of costs and benefits in atopic dermatitis routine care in Germany.

BACKGROUND AND OBJECTIVES: The economic burden of atopic dermatitis (AD) is of particular interest. The present study aims to analyse the association of disease-related characteristics, annual costs and treatment benefits in AD. METHODS: Between August 2017 and June 2019, a cross-sectional observational study in patients with AD was conducted in Germany. Cost-of-illness data were assessed from the societal perspective. Disease characteristics included severity, time since diagnosis and therapy, as well as atopic comorbidity and the implementation of prevention measures. Subgroup analyses of the total costs were conducted for these characteristics. A linear regression model was applied to analyse the impact of disease characteristics on the costs. Furthermore, associations of biologic treatment with outcome parameters were analysed. RESULTS: A total of 1291 patients from 111 centres were included in the analyses. The total costs amounted on average to € 3660 ± € 6428 per patient and year. Higher costs were shown in various patient groups, for example, in patients using biologics (€ 20 983 vs. € 2470). In a regression analysis, gender, education and the number of implemented prevention measures were identified as significant predictors of costs. Patients treated with biologics showed consistently better outcome parameters and were more often satisfied with their treatment. CONCLUSIONS: Gender, education and implemented prevention measures are significant cost determinants in AD. The results confirm that treatment with biologics is the main cost driver in AD. However, incremental patient-relevant benefits of high-priced therapy are reflected by the significantly better clinical outcomes in the group treated with biologics.

[Quality of care for patients with atopic dermatitis in Germany-no improvements in indicators after ten years]. / Qualität der dermatologischen Versorgung von Neurodermitis in Deutschland ­ keine Verbesserung der Indikatoren nach 10 Jahren.

BACKGROUND: With AtopicHealth1, the first national care study on atopic dermatitis (AD) was conducted in 2010. At that time, about one third of the patients undergoing treatment by dermatologists showed severe limitations in quality of life, which indicated an insufficient quality of care. The aim of the present study was to characterise the current care of patients with AD undergoing dermatological treatment in comparison between different severity grades, as well as in comparison to 2010 and to psoriasis. METHODS: The Germany-wide multicentre cross-sectional study "AtopicHealth2" recorded clinical data, quality of life (DLQI), therapies, preventive behaviour and patient-defined treatment benefit (PBI). Patients with an indication for systemic therapy were considered moderately to severely affected for subgroup analyses, the others mildly affected. RESULTS: Between 2017 and 2019, 1291 patients (median age 41 years, 56.5% female) were enrolled by 111 centres. Compared with 2010, there were no improvements in quality of life (DLQI 8.5 in both studies), severity (SCORAD 45.4 vs. 42.3 in 2010) or treatment benefit (PBI 2.2 vs. 2.4 in 2010). Moderately to severely affected patients were more likely to show impaired quality of life (45.4% vs. 23.6%) and less likely to have relevant treatment benefits (PBI < 1: 21.3% vs. 13.2%) than mildly affected patients. In contrast to psoriasis, patients with AD revealed higher quality of life limitations (DLQI 8.5 vs. 6.1) and lower treatment benefit (PBI 2.2 vs. 2.8). DISCUSSION: Compared to 2010, there is no improvement in the quality of care for AD in Germany. Compared to psoriasis, patients with AD show higher burden and lower treatment benefit, which underlines the need for therapeutic innovations.

Cost-of-illness of atopic dermatitis in Germany: data from dermatology routine care.

BACKGROUND: Progress in the management of atopic dermatitis (AD) and the recent introduction of the first biologic have raised interest in the costs of treating AD. OBJECTIVES: Since there is a lack of recent data, the objective of this study was to determine the annual costs of adults with AD from the societal perspective. METHODS: A nationwide cross-sectional study was conducted in 111 dermatological offices under routine conditions. Cost parameters were collected with a standardised questionnaire on disease-related costs. This questionnaire allows the determination of costs for systemic and topical treatment, outpatient and inpatient visits, rehabilitation stays and travel costs. Direct costs were determined for the statutory health insurance (SHI) and for the patients (out-of-pocket costs). Societal costs also included the indirect costs due to incapacity to work. Costs were calculated for all severity grades and further stratified by mild and moderate-to-severe AD. RESULTS: From August 2017 to June 2019, N = 1291 adult patients from all over Germany were included. The total annual costs in the group with all severity grades (n = 706) amounted to € 3616 ± € 6452 (median € 874) per patient. For patients with mild AD (n = 367), the annual costs were € 1466 ± € 3029 (median € 551) per patient, while they were € 5229 ± € 7538 (median € 1791) for patients with moderate-to-severe AD (n = 682). The total economic burden for treating adult patients with AD in Germany is estimated at more than € 2.2 billion. CONCLUSIONS: In total, the data from this study show that compared to for example psoriasis, AD has a moderate level of costs-of-illness in Germany. The approval of new therapies is expected to lead to markedly more resource utilisation in the next years.

Quality of psoriasis care in Germany - results from the nationwide health care studies PsoHealth 2004-2017.

BACKGROUND: In the study series PsoHealth first data from 2004/05 showed a poor quality of health care for psoriasis in Germany. Most patients lacked sufficient care and only a minor proportion received systemic drugs. Since 2007, a national psoriasis programme has been conducted. OBJECTIVES: (1) To analyse the quality of health care for psoriasis in the most recent PsoHealth4 survey 2016/17, (2) to compare health care quality indicators with prior assessments since 2004/05. MATERIALS AND METHODS: The recent cross-sectional PsoHealth4 survey was conducted 2016/17, and three preceding studies were performed in 2004/05, 2007 and 2013/14, each including at least 1500 patients. The common set of quality indicators included disease severity (PASI and proportion of patients with PASI > 20, indicating high severity), quality of life (DLQI and proportion of patients with DLQI > 10, indicating strong impairments in quality of life), systemic therapy and inpatient treatment of the last five years. RESULTS: Between December 2015 and December 2017, n = 1827 patients from 93 dermatological centres were included in the most recent survey (mean age: 50.8 ± 14.6 years, 45.2% female). 7.3% showed a PASI > 20, compared to 17.8% in 2004/05. 21.4% reported a DLQI > 10, compared to 34.0% in 2004/05. 57.6% of all participants stated to have received a systemic therapy at least once within the last five years, compared to 32.9% in 2004/05. 18.0% received inpatient hospital treatment at least once within the last five years, compared to 26.9% in 2004/05. CONCLUSION: A remarkable improvement in the health care quality for psoriasis patients in Germany within the past 12 years can be assumed. Major determinants could be the innovation shift which included programmes such as the S3 guideline, a consensus on treatment goals, national health care goals for psoriasis and higher utilisation of innovative drugs.

Characterizing treatment-related patient needs in atopic eczema: insights for personalized goal orientation.

BACKGROUND: Atopic eczema (AE) is a common and burdensome chronic skin disease. Clinical guidelines suggest an evidence-based, personalized and stepwise treatment approach. Only few studies have so far focused on the specific patient needs in treatment. OBJECTIVES: To characterize therapeutic needs of patients with AE in routine care. METHODS: Nationwide cross-sectional study in 91 dermatology practices and outpatient clinics. Descriptive statistics were used for valuation. Comparisons of HRQoL and general health status were performed including subgroups (age, gender and disease duration). Group comparisons of patient needs were performed for age groups, gender and disease duration. Correlations between patients' needs (PNQ) and HRQoL, generic health status and severity were tested. In addition, a hierarchical regression analysis was performed to determine which variables contribute to explain the variance in patient needs. RESULTS: Analysis of 1678 patients (60.5% female, mean age 38.35 ± 15.92 years) revealed a high disease burden with mean SCORAD of 42.26 ± 18.63, mean DLQI of 8.49 ± 6.45 and mean EQ VAS of 63.62 ± 21.98. Among the patient needs that were most frequently rated as 'quite important'/'very important' were as follows: 'to be free of itching' (96.0%), 'to get better skin quickly' (87.7%) and 'to be healed of all skin defects' (85.7%). In general, older people, women and patients who had been diagnosed with AE for 1 year or less rated the treatment needs as more important than younger patients, men and patients who had been diagnosed with AE for more than 1 year. Major determinants of higher needs were skin-related quality of life impairments, higher disease severity and higher age. CONCLUSIONS: Patients with AE show a high number and variety of therapeutic needs related to disease signs and symptoms, which are associated with individual disease burden. The patient needs vary substantially according to patient characteristics. Identification of patient-specific needs may support personalized, patient-centred care and shared decision-making.

Disease burden and patient needs and benefits in anogenital psoriasis: developmental specificities for person-centred healthcare of emerging adults and adults.

BACKGROUND: Establishing romantic relationships involving cohabitation and/or sexual intercourse is an overriding task for many people during emerging adulthood, i.e. from their late teens through the twenties. The diagnosis of anogenital psoriasis may hinder social/intimate relationships, resulting in higher disease burden in this age group. OBJECTIVES: To compare the disease burden and patient needs/benefits between emerging adults (18-30 years) and adults (>30 years) with psoriasis, with and without anogenital involvement; and to identify sociodemographic/clinical variables accounting for better patient-reported outcomes. METHODS: Patients aged ≥18 years with psoriasis vulgaris were recruited within a cross-sectional nationwide survey randomly assigning 157 dermatology practices/clinics in Germany. Anogenital involvement was established based on a high-resolution grid on the topology of psoriasis. The main outcome measures were the Psoriasis Area and Severity Index (PASI), the EuroQoL visual analogue scale (EQ-VAS), the Dermatology Life Quality Index (DLQI) and the Patient Benefit Index (PBI). RESULTS: Participants were 1921 patients: 173 emerging adults and 1749 adults >30 years. Anogenital involvement was observed in 621 patients (32.3%). Patient with anogenital psoriasis reported decreased health and more QoL impairments compared with those without anogenital lesions. Emerging adults presented more QoL impairments and less treatment benefits than older patients, and they were more prone to underrate a wide range of needs, except when the anogenital area was affected. Beyond anogenital involvement and higher disease severity, less treatment benefits were associated with more QoL impairments, particularly for emerging adults. CONCLUSIONS: The developmental instability of many emerging adults may result in difficulties to establish/adhere to treatment goals and thus in decreased perception of treatment benefit and more QoL impairments. Anogenital involvement is a risk factor for increased disease burden regardless of age. Assessing anogenital involvement in all patients and helping younger patients to define/adhere to treatment goals should be prioritized in patient-centred healthcare for psoriasis.

Does the Dermatology Life Quality Index (DLQI) underestimate the disease-specific burden of psoriasis patients?

BACKGROUND: The Dermatology Life Quality Index (DLQI) is the most frequently used health-related quality of life (HRQoL) instrument for skin diseases. According to the DLQI instructions, the responses 'not relevant' and 'my skin problem has not at all affected this aspect of life' ('not at all') have to be scored as 0 = no HRQoL impairments. OBJECTIVE: The aim of this study was to estimate potential bias of DLQI measurements for patients with psoriasis based on items considered to be not relevant. METHODS: One thousand two hundred forty-three patients with psoriasis were surveyed in a cross-sectional study. Disease severity (Psoriasis Area and Severity Index, PASI) and subjective health state (EuroQoL Visual Analogue Scale, EQ VAS) were compared per DLQI item between patients who answered the respective question 'not relevant' and those who answered 'not at all'. RESULTS: Patients who declared a DLQI item to be not relevant showed a higher disease severity and a lower health state. CONCLUSION: Results indicate that patients who declare a DLQI item to be not relevant have a higher disease-related burden than those who do not feel affected by their psoriasis in the same aspect of life. If aspects of life are considered to be not relevant due to high disease burden, this should be reflected by a HRQoL instrument.

Topology of psoriasis in routine care: results from high-resolution analysis of 2009 patients.

BACKGROUND: Different phenotypes have been described in psoriasis. Few details are known about the topology of patients in routine care. OBJECTIVES: To characterize the frequency and distribution of body sites affected by psoriasis in Germany. METHODS: Data from a national cross-sectional study (PsoHealth2) were analysed. Each practice consecutively recruited 20 patients independently of treatment. Topical distribution was identified with a detailed grid scheme of 1424 squares filled by the patient. Psoriasis history, clinical findings, comorbidity and patient-reported outcomes were obtained. RESULTS: In total, 2009 patients with psoriasis were observed. Nineteen per cent of patients had psoriatic arthritis, 65·4% had scalp involvement and 35·6% had nail involvement; in 40·5% of patients, their first-degree relatives also had psoriasis. In total, 1927 (95·9%) provided complete grid data. The mean number of grids marked was 152·4 ± 193·2, corresponding to 10·7% of body surface area. The most frequently affected body areas were the elbows, knees, lower legs and scalp (65-78%). In a linear regression analysis (corrected R² = 0·093), the strongest predictors of reductions in health-related quality of life (HRQoL), measured by the Dermatology Life Quality Index, were having the hands (ß = 0·147; P = 0·000), arms (ß = 0·097; P = 0·008), genitals (ß = 0·080; P = 0·010), neck (ß = -0·072; P = 0·043), scalp (ß = 0·068; P = 0·010) and nails affected (ß = 0·064; P = 0·005). CONCLUSIONS: Typical psoriatic lesions are found in real-world care. However, smaller areas are important determinants of reductions in HRQoL.

Definition of psoriasis severity in routine clinical care: current guidelines fail to capture the complexity of long-term psoriasis management.

BACKGROUND: Assessment of disease severity is an essential component of psoriasis management. Moderate-to-severe disease qualifies for systemic treatment but different definitions are used. OBJECTIVES: To analyse the impact of different severity definitions for psoriasis in real-world healthcare. METHODS: Cross-sectional data on 3274 patients with psoriasis from more than 200 dermatology offices and clinics across Germany were analysed for disease severity based on Psoriasis Area and Severity Index (PASI) and Dermatology Life Quality Index (DLQI). The proportions of patients having moderate-to-severe disease were determined accordingly. RESULTS: The proportion of patients meeting the European consensus criteria for moderate-to-severe psoriasis (PASI AND DLQI > 10) was 14·0%, although 45·3% attained at least PASI OR DLQI > 10. Consideration of all patients on systemic drugs as being 'moderate-to-severe' increased these proportions to 56·9% and 75·2%, respectively. When only PASI > 10 was used, moderate-to-severe disease affected 35·3% and 69·3%, respectively. CONCLUSIONS: The proportion of patients with psoriasis under dermatological care considered to have moderate-to-severe disease varies considerably according to how the latter is defined, resulting in uncertainty and inequity of access to systemic therapy. We propose an international standardisation in this for the sake of more reliable treatment and healthcare planning.

Measurement of healthcare quality in atopic dermatitis - development and application of a set of quality indicators.

BACKGROUND: Quality indicators are essential tools for the assessment of health care, in particular for guideline-based procedures. OBJECTIVE: Development of a set of indicators for the evaluation of process and outcomes quality in atopic dermatitis (AD) care. Application of the indicators to a cross-sectional study and creation of a global process quality index. METHODS: An expert committee consisting of 10 members of the German guideline group on AD condensed potential quality indicators to a final set of 5 outcomes quality and 12 process quality indicators using a Delphi panel. The outcomes quality and 7 resp. 8 process quality indicators were retrospectively applied to a nationwide study on 1678 patients with atopic dermatitis (AtopicHealth). Each individual process quality indicator score was then summed up to a global index (ranges from 0 [no quality achieved] to 100 [full quality achieved]) displaying the quality of health care. RESULTS: In total, the global process quality index revealed a median value of 62.5 and did not or only slightly correlate to outcomes quality indicators like the median SCORing Atopic Dermatitis (SCORAD; rp = 0.08), Dermatology Life Quality Index (DLQI; rp = 0.256) and Patient Benefit Index (PBI; rp = -0.151). CONCLUSION: Process quality of AD care is moderate to good. The healthcare process quality index does not substantially correlate to the health status of AD patients measured by 5 different outcomes quality indicators. Further research should include the investigation of reliability, responsiveness and feasibility of the proposed quality indicators for AD.

Cost-of-illness of psoriasis - results of a German cross-sectional study.

BACKGROUND: Though psoriasis poses a substantial chronic socio-economic burden, few studies have addressed the economic impact in Germany. OBJECTIVES: The objective was to evaluate the annual costs of psoriasis in Germany from the societal perspective. METHODS: A cross-sectional study was performed in randomly selected German dermatology practices and clinics in 2013/2014 using standardized questionnaires of illness-related costs. Costs were grouped by perspective and category as well as analysed by sex and age. Group differences were tested by non-parametric tests. RESULTS: Complete data were obtained from 1158 patients in 132 centres. Annual average costs for patients with psoriasis: total costs € 5543 ± € 8044, systemic treatment costs (paid by the statutory health insurances [SHI]) € 3733 ± € 7322, out-of-pocket costs € 224 ± € 406, total SHI costs € 4940 ± € 7533, direct costs € 5164 ± € 7581 and indirect costs € 379 ± € 2087. Significant higher costs in male and significant lower costs in 65+-year-old patients were found. CONCLUSIONS: Psoriasis induces a considerable economic burden. Between 2003 and 2014, costs have markedly shifted from hospital, out-of-pocket and indirect costs towards systemic drug costs.

Patient benefits in the treatment of psoriasis: long-term outcomes in German routine care 2007-2014.

BACKGROUND: Psoriasis is associated with significant patient burden. Few studies have specifically measured patient preferences and benefits. OBJECTIVES: Outcomes assessment using the Patient Benefit Index (PBI) in nationwide psoriasis surveys comparing health care in 2007 and 2014. METHODS: This was a non-interventional, cross-sectional survey conducted in 2007 and 2014 in randomly selected dermatological practices and clinics recording by a) physicians: comorbidity, clinical severity (PASI, GCA), and b) patients: quality of life (DLQI, EQ-5D), patient-relevant therapeutic benefits (PBI) and previous and curent treatments. RESULTS: In 2014, a total of n = 1265 patients (43.4% female, mean age 51.9 ± 14.3 years.; mean disease duration 21.6 ± 15.4 years.) were included. Overall PBI was 2.8 ± 1.1. A total of 91.6% of patients showed a more than minimum clinically relevant benefit (PBI>1). Patients treated with biologics and biologics combined with conventional systemics showed the highest benefit compared to patients with conventional systemic treatment and patients treated with topical steroids. In comparison with the 2007 survey (n = 2009), there was an increase in PBI from 2.5 ± 1.1 to 2.8 ± 1.1 and a gain of patients with high benefits (PBI ≥3) by 30% (38.5% vs. 49.4%). CONCLUSION: In German routine care, psoriasis patients have shown increased therapeutic benefits over time with highest benefits deriving from biologics combined with systemics.

The German National Program on Psoriasis Health Care 2005-2015: results and experiences.

In 2005, the first national psoriasis survey in Germany revealed large deficits in health care particularly in patients with moderate to severe disease. The consecutive goal was to improve health care for psoriasis countrywide. For this, a large-scale national program was initiated starting with a comprehensive analysis of structures and processes of care for psoriasis. Patient burden, economic impact and barriers to care were systematically analyzed. In order to optimize routine care, a S3 guideline, a set of outcomes measures and treatment goals, were developed. Implementation was enforced by the German Psoriasis Networks (PsoNet) connecting the most dedicated dermatologists. The annual National Conference on Health Care in Psoriasis established in 2009 consented National Health Care Goals in Psoriasis 2010-2015 and defined a set of quality indicators, which are monitored on a regular basis. Currently 28 regional networks including more than 800 dermatologists are active. Between 2005 and 2014 7 out of 8 quality indicators have markedly improved, and regional disparities were resolved. e.g., mean PASI (Psoriasis Area Severity Index) dropped from 11.4 to 8.1 and DLQI (Dermatology Life Quality Index) from 8.6 to 5.9. A decade of experience indicates that a coordinated nationwide psoriasis program based on goal orientation can contribute to better quality of care and optimized outcomes.

Nail involvement as a predictor of concomitant psoriatic arthritis in patients with psoriasis.

BACKGROUND: Patients with psoriatic arthritis (PsA) suffer from increased burden of disease and impairments in quality of life. Early detection and treatment of PsA could contribute to the prevention of clinical and radiological progression. OBJECTIVES: To analyse the predictive value of clinical and patient-reported outcomes for concomitant PsA in a population-based cohort of patients with psoriasis. METHODS: We performed a retrospective analysis of data from three independent national cross-sectional studies on health care in psoriasis and PsA, conducted in Germany in the years 2005, 2007 and 2008. Patients with psoriasis were included in the study by dermatologists (n = 3520) and via the German patient advocacy group for psoriasis (n = 2449). In all studies, psoriasis history, clinical findings, PsA, nail involvement, health care and patient-reported outcomes were collected with standardized questionnaires. RESULTS: In the regression model on 4146 patients the strongest predictors for concomitant PsA were nail involvement [odds ratio (OR) 2·93, 95% confidence interval (CI) 2·51-3·42, P < 0·001] and inpatient hospital treatment (OR 1·63, 95% CI 1·38-1·93, P < 0·001). By contrast, scalp involvement was not a significant predictor. CONCLUSIONS: Patients with psoriasis seen by dermatologists and those in patient advocacy groups show clinical indicators of PsA, the most predictive being nail disease. In practice, a comprehensive assessment of clinical findings associated with PsA is needed.

Quality of health care of atopic eczema in Germany: results of the national health care study AtopicHealth.

BACKGROUND: The successful treatment of atopic eczema (AE) should result in the improvement of both physical symptoms and patient's quality of life (QoL). This study was conducted using a sample of dermatologists throughout Germany. This is due to dermatologists being the main health care providers of AE. OBJECTIVES: Obtaining reliable data on quality of care of AE from both the patient's and the physician's perspective. METHODS: This cross-sectional study assessed: the individual clinical history; dermatology-specific QoL (DLQI); state of health (EQ-5d-VAS); treatments; burden caused by disease and treatment; patient-defined treatment benefit (PBI). RESULTS: Data from 1678 adult patients (60.5% female, mean age: 38.4 ± 15.9) were analysed. The most frequently used treatments during the last five years were emollients (90.4%) and topical corticosteroids (85.5%). In this study, 75.8% of the patients felt only moderately or not at all impaired by their treatment. The mean DLQI (0 = minimum-30 = maximum QoL impairment) was 8.5 ± 6.5. The EQ-5d-VAS (100 = best possible) was 63.6 ± 22.0 on average. 26.6% reported suffering 'often' or 'every night' from sleeplessness due to severe itching. Mean PBI was 2.4 ± 1.1 (4 = maximum benefit). CONCLUSIONS: This study provides first data on the health care of adults with AE in Germany at a national level and reveals the need for a more effective care. Whereas most patients consider their treatment-related burden as low, the daily burden of the disease seems to be high: one third reports sleeplessness due to itching which indicates insufficient therapeutic regimes in these cases. A better implementation of the German national guideline for AE and a systematic analysis of the difficulties causing its limited effects is needed.

Willingness to pay and quality of life in patients with atopic dermatitis.

Atopic dermatitis (AD) is a frequent and burdensome disease. The objectives of this study were (1) to assess the willingness to pay (WTP) and quality of life (Qol) in AD patients and (2) to compare the results with data on other chronic skin diseases. To collect data, a non-interventional, cross-sectional nationwide postal survey on adult patients with clinically diagnosed AD was performed; socio-demographic data, clinical features/symptoms, WTP and QoL were recorded. WTP was assessed in three different approaches, including relative and absolute figures. Data from n = 384 AD patients (mean age 42.0, range 18-92, 69.8 % female) were analyzed. WTP for complete healing was on median 1,000 (average 11,884) and exceeded WTP in rosacea (median 500) but not in vitiligo (median 3,000). Mean Dermatology Life Quality Index (DLQI) was 8.5 (vitiligo 7.0; psoriasis 6.7; rosacea 4.3) and correlated with pruritus, xerosis and disturbed sleep. WTP and DLQI correlated only marginally (r s = 0.134, p = 0.01). In conclusion, AD patients show high WTP and markedly reduced QoL compared to other chronic skin diseases.

Willingness to pay and quality of life in patients with rosacea.

BACKGROUND: Rosacea is a chronic inflammatory dermatosis affecting >2% of the population. Willingness to pay (WTP) is a well established method which reflects the individual burden of disease. OBJECTIVES: Evaluation of WTP and quality of life (QoL) in patients with rosacea. METHODS: Nationwide postal survey on adult patients with rosacea affiliated with the German rosacea patient advocacy group. WTP was evaluated by three standardized items and compared to historical data on vitiligo (n = 1023). QoL was assessed using the Dermatology Life Quality Index (DLQI). RESULTS: Data from n = 475 rosacea patients (79.9% women, mean age 56.3, range 26-90) were analysed. On average, patients were willing to pay € 2880 (median € 500) for complete healing compared with € 7360 (median € 3000) in vitiligo. Relative WTP was higher in women; the highest sums were registered for the age group 21-30 years. The extent of facial involvement predicted a higher relative WTP, whereas WTP decreased with the duration of symptoms and age. Mean DLQI total score was 4.3 compared to 7.0 in vitiligo. In rosacea, the highest values were observed in patients <30 years. Severe QoL reductions (DLQI>10) were less frequent (11%) than in vitiligo (24.6%). The correlation between WTP and DLQI was significant (e.g. r = 0.249, P = 0.000 for relative WTP). CONCLUSION: Rosacea patients show a moderate WTP and average QoL reduction is mild. WTP proved to be a valid tool to assess patients' burden of disease. Patient education and the development of effective treatment options might still improve patients' satisfaction.

Quality of health care of rosacea in Germany from the patient's perspective: results of the national health care study Rosareal 2009.

OBJECTIVES: To obtain reliable data on quality of care of rosacea and to compare care indicators with those found in atopic dermatitis and psoriasis. PATIENTS AND METHODS: In this cross-sectional study, clinical history, health-related quality of life (HrQoL), medication and treatment benefit of patients with rosacea were assessed by standardized questionnaires. Data were compared to patients with atopic dermatitis and psoriasis. RESULTS: Almost all 475 participants (96.4%) had received topical therapy. 24% had used cortisone ointments. The mean Dermatology Life Quality Index (DLQI) was 4.3 ± 4.6 (atopic dermatitis: 8.5 ± 6.0, psoriasis: 6.7 ± 6.2). The Patient Benefit Index (patient-defined therapeutic benefit) was 1.9 ± 1.2 (psoriasis: 2.3 ± 1.1, atopic dermatitis: 2.1 ± 1.1). CONCLUSIONS: Only a small proportion of the rosacea patients had substantial impairments in HrQoL. Overall, their burden appears to be lower than in patients with atopic dermatitis or psoriasis. However, the lower therapeutic benefit and the high proportion of topical steroid use indicate a need for optimized therapy.
