Abstract
Though more common earlier in life, increasing attention is being focused on the development of cutaneous lupus erythematosus (CLE) in patients with advancing age. Studies show that CLE is more common in older populations than previously thought, and all CLE subtypes are possible in this group. Just like patients in the third or fourth decade of life, CLE may appear alongside or independent of systemic lupus erythematosus. Older populations manifesting CLE for the first time seem to have a lower risk of progression to systemic disease than younger peers, and are more commonly White. CLE must be carefully distinguished from other skin conditions that have a predilection for presentation in older populations, including rosacea, lichen planus, and other autoimmune conditions such as dermatomyositis or pemphigus/pemphigoid. It is thought that most CLE in older populations is drug-induced, with drug-induced subacute cutaneous lupus erythematosus being the most common subtype. Management of CLE in older patients focuses on eliminating unnecessary medications known to induce CLE, and otherwise treatment proceeds similarly to that in younger patients, with a few special considerations.

Abstract
Psoriasis is a chronic inflammatory condition associated with genetic and immunological susceptibility. The objective of the study was to evaluate pruritus and sleep quality in correlation (r) to psoriasis severity and to detect their impact on quality of life. Two hundred (200) patients with psoriasis were included. Psoriasis severity was determined using the psoriasis area severity index (PASI), the quality of life (QoL) was assessed by the psoriasis disability index (PDI) questionnaire, and the sleep quality was evaluated by the Pittsburgh sleep quality index (PSQI). Finally, the severity of itching was evaluated using a 12-item pruritus severity scale (PSS). Poor sleep quality was found in 16.0% of patients in this study. Poor sleep was detected among 50.0% of cases with severe psoriasis. PASI scores correlated significantly with sleep quality, duration and sleep disturbances (p < 0.001). The global PSQI and PASI were also significantly correlated (p = 0.004). In conclusion patients complaining of psoriasis exacerbated by pruritus and sleep problems demonstrated lower quality of life in all domains. Sleep disturbances and depressive symptoms impairing quality of life should be taken into consideration when screening patients suffering from psoriasis.

Abstract
Psoriasis studies increasingly employ outcomes that indicate complete disease resolution, yet remission and cure are poorly defined for psoriasis. We conducted a systematic literature review to identify definitions of psoriasis remission and cure reported in the literature. Medline, EMBASE, and The Cochrane Central Register of Controlled Trials databases were searched on July 22, 2020 for full-text studies providing definitions for psoriasis remission/cure. Definitions were analyzed descriptively for endpoint, time-frame, on/off treatment, patient-reported outcomes, and disease domains. We identified 106 studies that provided 41 unique remission definitions. Most definitions included endpoints based on Psoriasis Area and Severity Index (PASI), such as PASI75 (n=16 studies), PASI90 (n=10), PASI100 (n=10), and PASI of 0 (n=3), and descriptive endpoints related to 'skin clearance' (n=18). Few definitions specified time-frame, on/off treatment or other psoriasis-related disease domains. One small consensus-initiative defined drug-free remission for plaque psoriasis by BSA of 0 without any therapy for at least 12 months. While there is no cure for psoriasis, seven studies defined psoriasis cure using similar endpoints to those used to define remission. We identified a variety of definitions of psoriasis remission. These results will inform the development of consensus-based definitions for psoriasis remission to support efforts to improve research and clinical outcomes.

Comparing willingness-to-pay and time-trade-off as the measures of burden of psoriasis: A pooled analysis of community, hospital, and web-based samples in China. J Dermatol 2022; 49:1131-1138. [PMID: 35906766 DOI: 10.1111/1346-8138.16522] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2022] [Revised: 06/23/2022] [Accepted: 07/02/2022] [Indexed: 11/28/2022]
Abstract
Willingness-to-pay (WTP) and time-trade-off (TTO) are widely used as measures of disease burden. However, the sensitivity of the metrics has not been compared in psoriasis. This article aims to report WTP and TTO in Chinese psoriasis patients, and to compare the WTPcure (USD), WTPcontrol (%), and TTO regarding the sensitivity in measuring the burden of psoriasis. Patients were recruited from a community-based cohort, a tertiary hospital, and an online forum. WTP was elicited for two scenarios: WTP for controlling the disease and WTP for curing the disease. WTPcontrol was elicited by asking about the percentage of monthly income that the participant patients would like to pay to fully control the clinical symptoms of psoriasis and WTPcure was elicited as absolute money for curing the disease. The evaluation of WTP and TTO were referred to the Psoriasis Area and Severity Index (PASI) as the indicator of clinical severity, and the Dermatology Life Quality Index (DLQI) as the measure of impaired quality-of-life. Data distribution, concurrent validity, and capability of discriminating moderate-to-severe psoriasis (receiver operating characteristic curve, ROC) were compared among the indices. A total of 479 patients were enrolled from the cohort (88), hospital (175), and web (216). WTPcontrol was significantly higher in patients with PASI>10 than those with PASI<10, while TTO was significantly higher in patients with DLQI>10 than those with DLQI<10. WTP control showed a positive association with PASI in mild psoriasis (r = 0.36, p < 0.001), while TTO showed an inverse correlation to DLQI in different severity subgroups, respectively (r = -0.20, p = 0.001). ROC analysis showed consistent results that WTP control was superior in discriminating patients with PASI>10, while WTP control was better in discriminating DLQI>10. WTPcure demonstrated no significant results. WTPcontrol is superior in detecting mild psoriasis compared to TTO, while TTO is more sensitive in measuring the impaired QoL.

Abstract
Psoriasis alters patients’ quality of life. Among the disorders associated with psoriasis, sleep disorders are common, although they are not directly assessed by most quality-of-life scores. Thus, the specific evaluation of sleep disorders using dedicated scores is necessary, especially because such disorders alter patients;’ physical and psychological health. The relationship between psoriasis and sleep disorders has been shown in numerous studies, but has not yet been fully elucidated. The aim of this study was to update knowledge of sleep disorders in patients with psoriasis, through a review of the scientific literature since 1980. This work covers several topics of interest, such as sleep assessment methods, the prevalence of sleep disorders in patients with psoriasis, factors predictive of sleep disorders in patients with psoriasis, the impact of sleep disorders on comorbidities and quality of life, pathogenic mechanisms, obstructive sleep apnoea and restless leg syndromes, and the impact of biotherapy treatments on sleep disorders in patients with psoriasis.

Abstract
BACKGROUND Intense pulsed light (IPL), as a therapeutic approach for rosacea, had advantage in removing erythema and telangiectasia and was gradually accepted by rosacea patients, but there have been few studies on economic evaluation of this therapy. PURPOSE This study aimed to detect willingness-to-pay (WTP) of IPL treatment for rosacea and to conduct a benefit-cost analysis (BCA) among the Chinese population, so as to provide an economic reference for doctors to make treatment decisions. MATERIALS AND METHODS An observational, cross-sectional study assessed respondent's demographic characteristics and willingness-to-pay (WTP) of IPL and rosacea patients' clinical data and Dermatology Life Quality Index (DLQI). WTP was obtained by contingent valuation (CV) method. In brief, contrast figures of three cases treated with IPL (Case1, Case2, and Case3 represented the increasing severity of rosacea) were showed and WTP was inquired. The costs were obtained according the market and compared with WTP (benefits) to get a benefit-cost ratio (BCR). Predictors of cost-effective WTP were identified using the multivariable logistic regression model. RESULTS A total of 303 rosacea patients and 202 controls were included in the study. The average cost of a single IPL treatment for rosacea was USD 208.04 in Changsha, China. The mean WTP for Case 1, Case 2, and Case 3 was USD 201.57, 214.64, and 221.74, respectively. WTP was statistically lower for Case 1 than that for Case 2 or Case 3 (P<0.05). The BCRs were 0.85, 1.03, and 1.06 for Case 1, Case 2, and Case 3, respectively. WTP is significantly associated with household monthly income, previous treatment cost, and DLQI after adjustments for demographic characteristics (P<0.05). CONCLUSION IPL is an acceptable treatment for rosacea with moderate to severe erythema. For patients with relatively high income or severely impaired quality of life, IPL is an economically feasible therapy and deserves to be recommended.

Abstract
Cutaneous lupus erythematosus (CLE) is a chronic skin disease that significantly impacts quality of life (QOL). This study tested a novel method to measure QOL in CLE using willingness-to-pay (WTP) stated preferences, and aimed to determine which of nine domains of life are most affected by CLE. Twenty-one participants with CLE ranked the domains in order of impact on CLE-related QOL, and then stated how many United States dollars they would be willing to pay for a hypothetical cure for each domain. Eighty-one percent of participants were female; mean age was 42.4 years. Photosensitivity was ranked highest by 71.4% of respondents. Participants were willing to pay the most for a hypothetical cure for CLE specific to photosensitivity (median = $200,000), the least for a cure specific to self-care (median = $0). Participants were willing to pay a median of $1,000,000 for an overall cure for CLE. Limitations include a small sample size for this pilot study and that willingness-to-pay may be influenced by individual perception of money and socioeconomic factors. This study successfully pilot-tested a WTP method and ranking task for health-related QOL. Photosensitivity was the domain of life most affected by CLE, which is a domain unique to our novel tool.

Abstract
AIM The objective was to investigate factors influencing patients' willingness to pay (WTP) and physician's views on the cost of therapy for two contrasted chronic diseases, chronic heart failure and psoriasis. METHODS A cross-sectional survey was conducted in ten developing countries, using a stated WTP contingent valuation method. Multivariate analyses were performed by linear regression. RESULTS Independent factors influencing patient WTP were income (+0.04 $PPP [purchasing power parity] in WTP per $PPP in monthly income; p < 0.001) and purchase of branded treatment for chronic heart failure therapy, and income, out-of-pocket treatment costs but also education level higher than secondary school (+115 $PPP in WTP comparatively to patients with none/primary school level; p = 0.008) for psoriasis therapy, suggesting the influence of sociopsychological factors in this disease. CONCLUSION Disease-specific factors may affect WTP for treatment that should be accounted for to support effective public health programs in developing countries.

Abstract
BACKGROUND There have been few studies on economic evaluation of acne treatments. Chemical peel (CP), a treatment approach primarily aimed at removing acne hyperpigmentation and scarring, is gradually accepted in the Chinese market. OBJECTIVES This study aimed to detect willingness-to-pay (WTP) and to conduct a benefit-cost analysis for CP treatment among Chinese acne patients. MATERIALS AND METHODS The costs were obtained from the patient's perspective and compared with benefits. The net benefits were approximated by WTP, using the contingent valuation method. A glycolic acid peel served as the demonstrated example. WTP and related information were inquired via an online questionnaire among the Chinese population. Factors for WTP were identified using generalized linear models. The benefit-cost ratio (BCR) was calculated. Discounting was not considered for both WTP and costs. RESULTS The response rate of the survey was 95.4% among the 476 anonymous participants. The average cost for three-time CP treatment was USD 383.4. Statistically significant differences in WTP among the cases were identified. The mean WTP for Case 1, Case 2, and Case 3 was USD 234.6, 222.0, and 401.7, respectively. A statistically significant association between WTP and self-reported acne severity was observed for all cases after adjustments for demographic characteristics (P<0.01). The Cardiff Acne Disability Index was positively associated with WTP. The BCRs were 0.61, 0.58, and 1.4 for Case 1, Case 2, and Case 3, respectively. CONCLUSION Patients with acne in China are willing to pay for acne treatment. Although the benefits of CP treatment have not generally outweighed their aggregated costs, WTP for CP treatment was positively associated with self-reported acne severity and desirable efficacy of treatment. Individualized acne treatments are recommended to target a specific population in the Chinese market.

Surgical versus medical treatment for ocular surface squamous neoplasia: A quality of life comparison. Ocul Surf 2018; 17:60-63. [PMID: 30217629 DOI: 10.1016/j.jtos.2018.09.001] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2018] [Revised: 07/08/2018] [Accepted: 09/06/2018] [Indexed: 11/21/2022]
Abstract
PURPOSE To characterize vision-related and psychosocial quality of life (QoL) parameters in medically and surgically treated patients with OSSN. METHODS Forty-one patients with OSSN treated with medical therapy consisting of interferon alpha 2b drops 1 MIU/ml (n = 22) or who underwent surgical excision (n = 19) were contacted. All subjects answered a quality of life assessment with an original questionnaire in which they were asked about a range of parameters. Overall satisfaction and motivating factors for treatment were also reviewed. RESULTS The mean age at the time of the survey was 64.6 and 51% were male with similar demographics between groups. Based on the previous cohort, rates of tumor resolution and recurrences were comparable in the two groups. Reasons for choosing a particular treatment varied between the groups. Forty percent of individuals in the medical group reported a fear of surgery (p = 0.03) and often made the decision after personal research (p = 0.008). Thirty-two percent of patients in the surgical group chose surgery due to fear of decreased vision due to lesion growth, therefore wanting immediate resolution (p = 0.09). Drops precipitated more ocular symptoms such as tearing and itchiness, on the other hand, patients who had surgery reported having more pain. CONCLUSION Quality of life considerations before, during, and after OSSN treatment is an important yet understudied topic. Our study is the first to look at QoL parameters in OSSN treatment and we found that patients in both medically and surgically treated groups had similar QoL metric but were driven to choose chemotherapy due to fear of surgery and/or prior literature review.

Abstract
BACKGROUND Plaque psoriasis can have a significant negative effect on patients' quality of life, and treatments can result in serious toxicities. Although there have been several studies of patients' and physicians' relative preferences for the benefits and risks of psoriasis treatments, it is unclear how and whether patients' and physicians' preferences for the outcomes of psoriasis treatments differ. OBJECTIVES To quantify patient and dermatologist preferences for improvements in psoriasis symptoms and for increases in the risk of treatment-related serious adverse events. METHODS Members of the U.K. Psoriasis Association and U.K. dermatologists with experience prescribing biologics completed a web-enabled discrete-choice experiment survey in which they evaluated efficacy and safety features of biological treatments for psoriasis. Choices between hypothetical treatment options were used to estimate preference weights indicating respondents' relative trade-off preferences among treatment outcomes. These outcomes included improvements in the severity and coverage of psoriatic plaques and treatment-related risks of tuberculosis, serious infections and lymphoma. Preference estimates were used to derive the maximum level of side-effect risks that respondents would accept for improvements in psoriasis symptoms. RESULTS Respondents' tolerance for side-effect risks varied with side-effect severity and location of plaques, and risk tolerance for serious side-effects was greater for patients than for dermatologists. CONCLUSIONS Estimates of patients' risk tolerance for serious side-effects indicate that patients valued psoriasis symptom control highly and suggest that psoriasis symptoms have a significant effect on patients' quality of life. In light of research showing increased treatment satisfaction and improved treatment adherence among patients who receive therapies that are consistent with their preferences, our findings suggest that greater communication between dermatologists and patients about risk tolerance could help improve patient care.

Abstract
Background: Some aspects of psoriasis treatments can negatively influence patients' quality of life. There is evidence from previous preference-elicitation research in psoriasis that administration characteristics are at least as important as treatment outcomes to patients. Objectives: Our objective was to test the hypothesis that patients' preferences for reduced disease and treatment burden are as important as preferences around treatment efficacy. We evaluated patient preferences for attributes of psoriasis treatments, including efficacy, tolerability, and mode and frequency of administration. Methods: Adult patients in the United States with a self-reported physician diagnosis of psoriasis completed an online discrete-choice experiment survey. The survey included eight choice questions, each asking respondents to choose between pairs of hypothetical psoriasis medications defined by attributes including efficacy, adverse reactions, and mode and frequency of administration. A random-parameters logit regression model was used to model the preference data. Results from this model were used to calculate respondents' willingness to trade efficacy for reduced treatment burden. Results: A total of 397 respondents, with a mean self-assessed Psoriasis Activity and Severity Index score of 8.2 (SD, 9.8), provided data for analysis. Improvements in treatment efficacy were more important than improvements in speed of onset and were more important than most increases in the chance of treatment side effects. The maximum possible improvement in treatment efficacy offered in the study was not enough to match the improvements in well being associated with some changes in mode of administration. For example, respondents were willing to accept a reduction in the percentage of patients who achieve clear or almost-clear skin after treatment from approximately 70% to 40% to avoid injections at home and use a topical treatment. Topical treatments were the most preferred option of administration followed by oral agents and intravenous infusion. Conclusions: Psoriasis patients had well-defined preferences for changes in the treatment attributes considered. Avoiding injections in favor of oral or topical treatment was more important to patients than some improvements in efficacy. These findings support previous research regarding the importance of treatment burden relative to outcomes in psoriasis and emphasize the importance of individual patient preferences in determining treatment strategy.

Abstract
BACKGROUND Psoriasis is a long-term immune-mediated inflammatory disorder mainly, but not only, affecting skin, and is associated with significant medical and psychological morbidity. Evidence suggests that sleep is disrupted in psoriasis, however high quality empirical evidence is lacking. Given the importance of sleep for health, characterisation of sleep disruption in psoriasis is an important goal. We therefore conducted a systematic review of the sleep-psoriasis literature. METHODS Searches were conducted in Pubmed, SCOPUS and Web of Science from inception to May 2016. Studies were compared against inclusion/exclusion criteria and underwent a quality evaluation. Given the heterogeneity of studies, we conducted a narrative synthesis of the findings. RESULTS Searches revealed 32 studies which met our predetermined inclusion/exclusion criteria. Whilst 93.7% of studies reported sleep disruption in this population, ranging from 0.05% to 85.4%, many had important methodological shortcomings. Over half of all quantitative studies (54.8%; 17/31) relied on non-validated measures, contributing to heterogeneity in study findings. In those that employed valid measures, assessing sleep was often not the primary objective. We frequently found the absence of adequate sample size calculations and poor statistical reporting. CONCLUSION This review showed that in psoriasis, reported sleep rates of sleep disturbance varied substantially. Most studies lacked a hypothesis driven research question and/or failed to use validated measures of sleep. We were unable to draw firm conclusions about the precise prevalence and nature of sleep disturbance within the psoriasis population. We offer suggestions to help advance understanding of sleep disturbance in psoriasis.

Abstract
Telemedicine is the use of telecommunications technology to support health care at a distance. Technological advances have progressively increased the ability of clinicians to care for diverse patient populations in need of skin expertise. Dermatology relies on visual cues that are easily captured by imaging technologies, making it ideally suited for this care model. Moreover, there is a shortage of medical dermatologists in the United States, where skin disorders account for 1 in 8 primary care visits and specialists tend to congregate in urban areas. Even in regions where dermatologic expertise is readily accessible, teledermatology may serve as an alternative that streamlines health care delivery by triaging chief complaints and reducing unnecessary in-person visits. In addition, many patients in the developing world have no access to dermatologic expertise, rendering it possible for teledermatologists to make a significant contribution to patient health outcomes. Teledermatology also affords educational benefits to primary care providers and dermatologists, and enables patients to play a more active role in the health care process by promoting direct communication with dermatologists.

Abstract
INTRODUCTION Previous studies have shown that psoriasis has a significant effect on patients' health-related quality of life. The impact of psoriasis on household chores and the need for assistance with such tasks are not well documented. The aim of this study was to estimate the impact of psoriasis on the ability to carry out household chores, the time spent on skin care at home and the assistance that patients with psoriasis require with these activities. METHODS In a questionnaire study 262 patients with moderate-to-severe psoriasis, visiting a tertiary level dermatological clinic during a 1-year study period, listed household chores which they considered were particularly affected by psoriasis. This was done without a predefined list of chores. Questions on their ability to perform household chores as well as time spent on skin care at home were asked. The need for outside assistance with household chores and help received were also determined. RESULTS More than half of the patients (57.8%) reported difficulties with household chores because of psoriasis. Psoriasis affected a wide range of everyday household activities, with physically demanding tasks and those involving contact with water mentioned most often. Most of the patients (84.6%) reported that they have increased the time spent on skin care because of psoriasis, on average by 87 min per week. A quarter of patients received assistance in household chores. Women received more assistance than men (p < 0.01). The need for additional assistance was reported by a fifth of patients, women more often than men (p < 0.05). CONCLUSION When estimating the overall burden of psoriasis, considering only the economic and productivity consequences may underestimate the impact of the disease. The impact on everyday life events such as the ability to perform household chores should also be taken into account.

Abstract
Background: Currently available topical treatments for actinic keratosis (AK) adversely affect patients' quality of life because of long treatment durations and long-lasting local skin reactions (LSRs), which may result in poor treatment adherence and patient outcomes. Ingenol mebutate gel, a recently introduced treatment for AK, is administered for 2 or 3 days, and LSR's are predicable in onset and duration. Objectives: The objective of the study was to estimate the value of ingenol mebutate gel's shorter treatment duration and tolerability profile to potential patients, versus existing topical treatments (imiquimod 3.75%, imiquimod 5% and diclofenac 3%) in the United States. Methods: The open-ended Contingent Valuation (CV) approach was used to estimate incremental willingness-to-pay (WTP) for ingenol mebutate gel rather than treatment with imiquimod 5%, imiquimod 3.75% and diclofenac 3%. Profiles for each therapy differed in regards to treatment duration, time-to-LSR resolution, and price. Subjects were asked to state their maximum out-of-pocket WTP to receive ingenol mebutate gel instead of each of the three alternatives. Results: 103 subjects provided usable answers. Between 48% and 63% of subjects were willing to pay extra to gain access to treatment with the ingenol mebutate gel profile instead of the comparators, and the mean incremental WTP ranged from $475 to $518. Subjects with experience of topical treatment stated higher WTP for accessing ingenol mebutate gel. Subjects whose most bothersome AK area was the full scalp or forehead also claimed higher WTP for ingenol mebutate gel. Conclusions: Patients diagnosed with AK indicated an unmet need for fast-acting topical treatment with shorter LSR resolution time.

Abstract
BACKGROUND A 2010 CDC-sponsored consultation of psoriasis, psoriatic arthritis, and public health experts developed a public health agenda for psoriasis and psoriatic arthritis indicating that additional population-based research is needed to better characterize psoriasis in the population. PURPOSE To better characterize the burden of psoriasis in the U.S. using recent population-based, cross-sectional data in this 2012 analysis. METHODS A subset of 10,676 adults aged 20-59 years from the 2003-2006 and 2009-2010 National Health and Nutrition Examination Surveys was used to examine psoriasis prevalence, severity, disparities, health-related quality of life, and selected comorbidities. RESULTS The overall prevalence of psoriasis was 3.1% (95% CI=2.6, 3.6); extrapolating to older adults suggests that 6.7 million adults aged ≥20 years are affected. Psoriasis was significantly more prevalent among non-Hispanic whites than other race/ethnicity subgroups, as well as among those with arthritis. Approximately 82% reported no/little or mild disease; the impact of psoriasis on daily life increased with disease severity (p=0.0001 for trend). Those with psoriasis reported significantly more frequent mental distress or mild to severe depression than those without psoriasis. Psoriasis was also significantly associated with obesity and former smoking status. CONCLUSIONS Psoriasis is a large public health problem. Further characterizing psoriasis from a public health perspective will require better survey questions and inclusion of these questions in national surveys.

Abstract
BACKGROUND Many studies show gender and ethnic differences in healthcare utilization and outcomes. Patients' presurgical cognitions regarding surgical outcomes also may vary by gender and ethnicity and play a role in explaining utilization and outcome differences. However, it is unclear whether and to what extent gender and ethnicity play a role in patients' presurgical cognitions. QUESTIONS/PURPOSES Do gender and ethnicity influence outcome expectations? Is arthroplasty-related knowledge affected by gender and ethnicity? Do gender and ethnicity influence willingness to pay for surgery? METHODS In a prospective, multicenter study we gave 765 patients an anonymous questionnaire on expectations, arthroplasty knowledge, and preferences before their consultation for hip and/or knee pain, from March 2005 to July 2007. RESULTS Six hundred seventy-two of the 765 patients (88%) completed questionnaires. Non-Hispanics and men were more likely to indicate they would be able to engage in more activities. Non-Hispanics and men had greater arthroplasty knowledge. Hispanics and women were more likely to report they would not pay for a total joint arthroplasty (TJA) relative to non-Hispanics and men. CONCLUSIONS Sex and ethnic differences in patients presenting for their initial visit to the orthopaedists for hip or knee pain influence expectations, knowledge, and preferences concerning TJAs. Longitudinal study of relationships between patients' perceptions and utilization or outcomes regarding TJA is warranted.

Abstract
BACKGROUND Patient education in addition to standard treatment, with the aim of affecting care through courses, is a relatively new concept in dermatology. Here we introduce a randomized controlled trial (RCT) regarding a previously described 12-week educational programme for chronic skin diseases. OBJECTIVES The primary objective of the RCT was to measure the effect of an educational programme on disease severity and quality of life in patients with psoriasis or atopic dermatitis. METHODS We recruited 50 patients from Ghent University Hospital. Patients with diagnosed psoriasis or atopic dermatitis were randomized (1 : 1) to the intervention or control group. The clinical outcome was measured by two blinded observers using the Psoriasis Area and Severity Index (PASI), Scoring Atopic Dermatitis or the Eczema Area and Severity Index. Quality of life was measured by dermatology-specific quality-of-life questionnaires. There was a follow-up period of 9 months. RESULTS We found that disease severity and quality of life improved significantly for patients with psoriasis (n = 29) but not for patients with atopic dermatitis (n = 21) at 3 months. Patients in the intervention group showed a significant reduction in mean PASI (P = 0·036), mean Dermatology Life Quality Index (P = 0·019) and mean Psoriasis Disability Index (P = 0·015), compared with the control group at 3 months. This improvement continued for at least 6 months, i.e. 3 months after the intervention, but was lost at follow-up after 9 months. CONCLUSIONS Evaluating this form of educational programme, by means of a single-centre RCT, indicates its added value in the longer term management of psoriasis.

Abstract
BACKGROUND Patient preferences for psoriasis treatments can impact treatment satisfaction and adherence and may therefore influence clinical outcome. OBJECTIVE To assess the impact of treatment experience (satisfaction with current treatment, number of prior visits, disease duration, number of preceding therapies and currently prescribed treatment modalities) on treatment preferences. METHODS A computer-based conjoint analysis experiment was conducted to analyse preferences of patients with moderate or severe psoriasis (n = 163) treated at a German University Medical Center for outcome (probability, magnitude and duration of benefit; probability, severity and reversibility of side effects) and process attributes (location, frequency, duration, delivery method, individual cost) of psoriasis treatments. Relative importance scores (RIS) were calculated for each attribute and compared using anova, post hoc test and multivariate regression analysis. RESULTS Participants with longer disease duration attached significantly greater importance to duration of benefit (β = 0.206, P = 0.018), whereas participants on oral therapy were more concerned about magnitude of benefit by trend (β = 0.218, P = 0.058). Participants receiving injectables not only set higher value to probability of benefit (RIS = 32.80 vs. 21.89, P = 0.025) but also to treatment location (RIS = 44.74 vs. 23.03, P = 0.011), delivery method (RIS = 43.75 vs. 19.29, P = 0.019), treatment frequency (RIS = 31.24 vs. 16.89, P = 0.005) and duration (RIS = 32.54 vs. 16.57, P = 0.003) when compared with others. Treatment satisfaction was significantly higher in participants on infusions or injections compared with those on phototherapy and mere topical therapy. CONCLUSIONS Treatment preferences may change over time course and with treatment experience. Participants on injectables attach great importance to efficiency and convenience of therapies, and are highly satisfied with their treatment.

Abstract
BACKGROUND An obesity epidemic is spreading worldwide. In addition to comorbidities, social and emotional problems contribute to reduce the quality of life (QoL) of obese people. Considering the heterogeneity of outcomes from clinical and surgical approaches, it is recommended that severely obese patients participate in their treatment decisions. This study evaluated preferences of severely obese patients for obesity surgical treatment using the willingness to pay (WTP) and to assess the impact of the presence of some clinical disorders, socioeconomic conditions and QoL on their decisions. METHODS The selected patients were invited to answer the WTP questionnaire using two formats of contingent valuation questions: dichotomous choice (yes/no) and a bidding game. The answers were correlated with clinical features, QoL assessed by the SF-36 and the Moorehead-Ardelt Quality of Life Questionnaire II, Brazilian socioeconomic classification, and family and personal incomes. RESULTS The group of patients who accepted the first bid was older and had higher frequency of sleep apnoea when compared to those who rejected the offer. A significant correlation between the bidding game value and family income was found (r = 0.28; P < 0.02). In the logistic regression model, socioeconomic classification and sleep apnoea were shown to be independently associated with acceptance the bid. CONCLUSIONS Sleep apnoea was the comorbidity that most influenced the acceptance in dichotomous choice for bariatric surgery, probably due to the deleterious effects on daily activities induced by sleep disturbances. Our findings also suggest that the frequency of surgical procedures is below the preference of the obese population in Brazil.

Abstract
BACKGROUND Non-adherence rates are high among patients with psoriasis, partly because of discordance between recommended treatments and individual preferences. OBJECTIVES Our aim was to assess the impact of comorbidities on patients' preferences for psoriasis treatments. METHODS A computer-based conjoint analysis experiment was conducted to analyze preferences of patients with psoriasis (N = 163) for treatment outcome attributes (probability, magnitude and duration of benefit; probability, severity and reversibility of side effects) and process attributes (treatment location, frequency, duration, delivery method, individual cost). The impact of comorbidities (psoriatic arthritis, cardiovascular disease, diabetes, and depression) on relative importance scores of each attribute was assessed by analyses of variance, post hoc test, and multivariate regression analysis. RESULTS Among the participants included (58.9% males, mean age 49.3 yrs), 27% suffered from psoriatic arthritis, 13.5% from cardiovascular disease, 8% from diabetes, and 12.9% from depression. Preferences for treatment attributes varied significantly depending on comorbidities. Participants with psoriatic arthritis cared most about the probability of benefit (β 0.166; P = .037), whereas those participants with cardiovascular disease were highly concerned about the probability of side effects (β 0.179; P = .046). For participants with depression, treatment duration (β 0.163; P = .047), and individual cost (P = .023) were highly important. LIMITATIONS Only patients with moderate and severe psoriasis treated at a university medical center were included. CONCLUSIONS Integrating patients' preferences into shared decision-making may facilitate treatment adherence and optimize outcomes. Addressing patients' comorbidities, particularly depression, may be a currently neglected opportunity to improve care.

Abstract
OBJECTIVES Psoriatic arthritis (PsA) is a seronegative inflammatory arthritis found in up to 5 to 42% of patients with psoriasis. As current instruments do not fully capture health-related quality of life (HR-QOL) in PsA from the patient's perspective, we piloted a novel application of "willingness-to-pay" (WTP) as a Patient Reported Outcome to measure the relative impact of PsA in 8 domains of HR-QOL. METHODS Fifty-nine PsA patients were interviewed on 8 WTP HR-QOL domains (physical, emotional, sleep, work, social, self-care, intimacy, and concentration). Participants were asked to rank the 8 domains of health in order of HR-QOL impact. In each domain, participants were asked whether PsA affected that domain, whether they were willing to pay for a cure in that domain, and the amount they were willing to pay. Median WTP amounts were compared with the proportion of participants affected by and willing to pay in each domain. Responses in US dollars were interpreted as strength of preference rather than absolute monetary values. RESULTS The majority of participants were white (98%), > or =45 years of age (70%), insured (98%), and earned >$65,000/yr (66%). The physical domain was most affected by PsA; intimacy and concentration were ranked lowest. Participants reported a wide range of WTP amounts ($0 to $1,000,000), and median WTP amounts were highest in the physical, work, sleep, and self-care domains. Related domains elicited median WTP amounts that were highly correlated. No significant differences in median WTP amounts were found across ages, genders, and income levels for the different domains. CONCLUSIONS WTP is a novel quantitative patient-perspective measure that is comprehensible and feasible to administer in PsA patients. It represents a unique tool for capturing the complex manifestations of PsA and its impact on the individual, allowing the quantification of specific HR-QOL parameters and providing the potential for comparison across various disease processes in a given individual.
