Switch to biological agent in psoriasis significantly improved clinical and patient-reported outcomes in real-world practice

Disease severity, treatment patterns, and quality of life in patients with moderate-to-severe psoriasis routinely managed with systemic treatment: results of the CRYSTAL observational study in Central and Eastern European countries

Psoriasis is a common, life-long skin disease with a significant negative health and societal impact. Data on rates of disease control and treatment strategies are lacking in Central and Eastern European countries. We aimed to describe the real-world disease severity, control, and treatment strategies for psoriasis in patients from Central and Eastern European countries. CRYSTAL (EUPAS36459) was a cross-sectional, retrospective study in adults (18-75 years) from Bulgaria, Estonia, Hungary, Latvia, Lithuania, Romania, and Russia. We enrolled patients with moderate-to-severe psoriasis receiving continuous systemic treatment for ≥24 weeks. We used the Psoriasis Area and Severity Index (PASI) to describe disease severity and the Dermatology Life Quality Index (DLQI) to assess quality of life (QoL) and collected other outcomes [psoriasis work productivity and activity impairment (WPAI-PSO), patient satisfaction] at enrollment. Analyses were descriptive. A total of 690 patients were included in the analyses. Median disease duration was 11.8 years. Current treatment was monotherapy for most patients (95.8%) with either biological (BIO group; 88.4%) or conventional (NON-BIO group; 7.4%) agents. Mean (± standard deviation) absolute PASI scores were 3.5 ± 5.7, 3.1 ± 5.3, and 6.6 ± 7.4 in the overall population, the BIO group, and the NON-BIO group, respectively. Among patients treated with monotherapy, absolute PASI scores ≤1, ≤3, and ≤5 were observed for 44.1%, 72.0%, and 82.6% of BIO patients and 21.6%, 33.3%, and 49.0% of NON-BIO patients. Mean DLQI total score was 3.3 ± 5.1; higher scores were noted for higher absolute PASI. The most impacted WPAI-PSO domain was presenteeism; for all domains, impact increased with increased absolute PASI. A total of 91.8% of BIO patients and 74.5% of NON-BIO patients were satisfied with the current treatment. We observed a better disease control in BIO than NON-BIO patients. However, around half of BIO patients did not reach clear skin status and reported an impact on QoL. An improvement in treatment strategies is still needed in Central and Eastern European countries to optimize outcomes of moderate-to-severe psoriasis.

Real-world switching patterns and associated characteristics in patients with psoriasis treated with biologics in the United States

BACKGROUND

Switching therapies is common for patients with psoriasis.

OBJECTIVE

To quantify real-world switching rates and characteristics among patients initiating biologics over 24 months.

METHODS

Patients aged ≥18 years with ≥2 confirmed psoriasis diagnoses who initiated a new biologic were identified from a US-payer claims database (Merative® MarketScan^® Switching rates were reported over 24 months using Kaplan-Meier survival analysis, and multivariable Cox regression analyses were performed to identify associated patient characteristics.

RESULTS

7,997 patients were included, with overall treatment switch rates at 14.4% at 12 months and 26.0% at 24 months. IL-23 inhibitors were associated with the lowest risk of switching compared with TNF, IL-17, and IL-12/23 inhibitors over 24 months (P < 0.0001). Switch rates varied between specific biologics, with the lowest switch rates observed for patients treated with risankizumab at 8.5% followed by guselkumab at 15.7% over 24 months. Prior targeted immune modulator use, age, and female gender were predictors of switching (adjusted hazard ratio; 1.23, 1.31, and 1.40, respectively; P ≤ 0.0005).

LIMITATIONS

Claims data may be subject to data errors and reasons for switching cannot be determined.

CONCLUSION

Switching was common in psoriasis patients using biologics over 24 months, with the lowest risk of switching observed with IL-23 inhibitors.

A Cross-Indication Budget Impact Model of Secukinumab for the Treatment of Psoriasis, Psoriatic Arthritis, Ankylosing Spondylitis and Non-radiographic Axial Spondyloarthritis in Italy

BACKGROUND

Recent developments improved outcomes in patients with autoimmune diseases. Biologics were approved as first-line treatment in selected naïve patients with plaque psoriasis (PsO), psoriatic arthritis (PsA), ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nr-axSpA). Among them, secukinumab was most recently approved for treatment of active nr-axSpA in adults. In this work, we assessed the budget impact of new secukinumab treatment options in the Italian market.

METHODS

A cross-indication budget impact model was designed to estimate the effects of adding secukinumab in the Italian market from the National Health System perspective over a 3-year period. The model included all adults with PsO, PsA, AS and nr-axSpA, treated with biologics or biosimilars. It compared costs between two scenarios, secukinumab availability or absence, for the four diseases combined and taken individually. A sensitivity analyses was conducted.

RESULTS

There were 68,121 adult patients treated with biologics in 2021 and 68,341 in 2023. The budget impact analysis (BIA) on all indications showed a cost reduction of €33.7 million (- 1.5%) over 3 years with the introduction of secukinumab. PsA patients had the highest saving (- €34.9 million), followed by PsO patients (- €7.8 million). Cost saving in PsO patients was balanced by increased budget reported in AS patients (+ €8.0 million). In nr-axSpA patients, secukinumab reported no significant budget increase (+ 1.0%).

CONCLUSION

This BIA accounted for the new indication of secukinumab in nr-axSpA patients, reporting no significant changes in the required budget and adding an effective treatment option. Considering all indications, secukinumab is a sustainable treatment option.

Experiences and coping behaviours of patients with psoriasis: a qualitative study

BACKGROUND

Psoriasis is a complex, chronic, lifelong inflammatory skin disease characterized by the development of erythematous, indurated, scaly, pruritic and often painful skin plaques, and it is currently incurable. It profoundly affects psychological wellbeing and social functioning and has significant associated co-morbidities. To improve clinical approaches, understanding of the experiences of patients with psoriasis is needed.

OBJECTIVE

To explore the experiences and coping behaviours of patients with psoriasis.

METHODS

A qualitative study approach was conducted. Through semi-structured interviews, 20 patients with psoriasis were recruited from general practices and specialist dermatology practices in a regional teaching hospital in Taiwan. Recorded interviews were transcribed and analysed by content analysis.

RESULTS

Three themes and nine subthemes were identified: 1. Symptoms distress: (a) trouble with scaling, (b) bothersome itching, and (c) complex pain experiences; 2. Psychological distress: (a) encountering discrimination and (b) feeling stigmatised; 3. Managing psoriasis: (a) coping with symptoms, (b) seeking alternative methods, (c) using biologic agents, and (d) changing thinking and coexisting with the disease.

CONCLUSION

The experience of patients with psoriasis has significant negative impacts on their lives. The findings of this study can provide healthcare professionals with a reference for the care of patients with psoriasis.

Effectiveness of brodalumab in improving itching and skin pain in Japanese patients with psoriasis: The ProLOGUE study

Itching and skin pain are bothersome symptoms of psoriasis, but evidence is limited regarding the treatment effectiveness on these symptoms in daily clinical settings. We assessed the changes in the levels of itching and skin pain after brodalumab treatment in Japanese patients with psoriasis using patient-reported outcomes (PROs). Patients with psoriasis who have inadequate response to existing treatments were enrolled in the single-arm, open-label, multicenter, prospective ProLOGUE study and received brodalumab 210 mg subcutaneously in daily clinical practice. Psoriasis Area and Severity Index (PASI) and PRO assessments were performed at baseline and weeks 12 and 48. Seventy-three patients (men, 82.2%; median age, 54.0 years) were enrolled. The Itch Numeric Rating Scale (NRS; p < 0.0001 at weeks 12 and 48) and Skin Pain NRS (week 12, p = 0.0004; week 48, p < 0.0001) scores significantly decreased from baseline. The Itch NRS score was significantly higher in patients with a Dermatology Life Quality Index (DLQI) score of ≥2 (vs. 0/1; p < 0.0001 at weeks 12 and 48) and in patients with a Treatment Satisfaction Questionnaire for Medication-9 (TSQM-9) global satisfaction domain score of ≤70% (vs. >70%; week 12, p = 0.0120; week 48, p = 0.0348). The Itch NRS score cutoff value for achieving a PASI score of ≤2, DLQI score of 0/1, and TSQM-9 global satisfaction domain score of >70% was 1 at week 12 and 0 at week 48. Brodalumab treatment was associated with improvement in itching and skin pain in Japanese patients with psoriasis. An Itch NRS score of 0 can be a long-term treatment goal for psoriasis (Japan Registry of Clinical Trials identifier: jRCTs031180037).

Demographics, Disease Characteristics, and Patient-Reported Outcomes Among Patients with Psoriasis Who Initiated Guselkumab in CorEvitas' Psoriasis Registry

Introduction

Guselkumab is approved for the treatment of both moderate-to-severe plaque psoriasis and active psoriatic arthritis (PsA) in the USA. However, little is known about patients initiating guselkumab in a real-world setting. The objective of this study was to describe baseline characteristics among patients with plaque psoriasis who initiated guselkumab at or after enrollment in CorEvitas’ Psoriasis Registry.

Methods

Adult patients who initiated guselkumab in the Psoriasis Registry between July 18, 2017 and November 6, 2018 were included. Demographics, disease characteristics, and patient-reported outcome measures (PROMs) were assessed at the time of guselkumab initiation (baseline). Patients with psoriasis were stratified according to the number of previously received biologics (0 to 4+) for comparison. A subset of patients with psoriasis and concomitant dermatologist-diagnosed PsA were stratified into biologic-naïve and biologic-experienced groups.

Results

Among 687 patients with psoriasis who initiated guselkumab, biologic-naïve patients and those with four or more prior biologics had the most severe disease and the worst PROM scores at baseline. Among 251 patients with concomitant dermatologist-diagnosed PsA, biologic-naïve patients had more severe disease and worse PROM scores than biologic-experienced patients.

Conclusions

These findings highlight important differences in baseline characteristics according to biologic experience among patients with plaque psoriasis with or without concomitant PsA initiating guselkumab in a real-world setting.

Utility of the Dermatology Life Quality Index at initiation or switching of biologics in real-life Japanese patients with plaque psoriasis: Results from the ProLOGUE study

BACKGROUND

Plaque psoriasis significantly affects patients' health-related quality of life. To aid treatment decisions, not only objective assessment by physicians but also subjective assessment by patients is important.

OBJECTIVE

To assess the significance of Dermatology Life Quality Index (DLQI) evaluation at the time of biologics introduction in clinical practice in Japanese patients with plaque psoriasis.

METHODS

This was a single-arm, open-label, multicenter study. At baseline, Psoriasis Area and Severity Index (PASI) and DLQI scores were measured and stratified based on DLQI scores ≥6/≤5 and PASI scores ≤10/>10. Other patient-reported outcomes assessed included EQ-5D-5L, itch numerical rating scale (NRS), skin pain NRS, Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-8 (PHQ-8), Sleep Problem Index-II (SPI-II), and Treatment Satisfaction Questionnaire for Medication-9 (TSQM-9).

RESULTS

Of the 73 enrolled patients, 23 had PASI scores ≤10. Those with PASI/DLQI scores >10/≥6 had a significantly higher median PASI score than those with PASI/DLQI scores >10/≤5 (p = 0.0125). Regardless of PASI scores (>10/≤10), median itch NRS and GAD-7 scores were significantly higher in patients with DLQI scores ≥6 than in those with DLQI scores ≤5 (itch NRS, p = 0.0361 and p = 0.0086, respectively; GAD-7, p = 0.0167 and p = 0.0273, respectively). Patients with PASI/DLQI scores ≤10/≥6 had significantly higher skin pain NRS (p = 0.0292) and PHQ-8 (p = 0.0255) scores and significantly lower median SPI-II scores (p = 0.0137) and TSQM-9 Effectiveness domain scores (p = 0.0178) than those with PASI/DLQI scores ≤10/≤5.

CONCLUSION

DLQI may be useful for assessing patients' concerns that cannot be identified by PASI alone while initiating biologics or switching from other biologics in clinical practice.

Sustained long-term efficacy and safety of adalimumab in paediatric patients with severe chronic plaque psoriasis from a randomized, double-blind, phase III study

BACKGROUND

Adalimumab (ADA) (Humira^® , AbbVie Inc., U.S.A.) is approved by the European Medicines Agency for children aged ≥ 4 years with severe plaque psoriasis.

OBJECTIVES

To evaluate the long-term efficacy and safety of ADA in children with severe plaque psoriasis.

METHODS

Results are presented from the 52-week long-term extension (LTE) of the randomized, double-blind, double-dummy, phase III trial, in children with severe plaque psoriasis (results from prior periods have been published). Patients aged ≥ 4 and < 18 years were randomized 1 : 1 : 1 to ADA 0·8 mg kg^-1 (40 mg maximum) or 0·4 mg kg^-1 (20 mg maximum) every other week or to methotrexate (MTX) 0·1-0·4 mg kg^-1 (25 mg maximum) weekly. The 16-week initial treatment (IT) period was followed by a 36-week withdrawal period and a 16-week retreatment period. Patients could enter the LTE at prespecified time points to receive ADA 0·8 mg kg^-1 (blinded or open label) or ADA 0·4 mg kg^-1 (blinded), or to remain off treatment. Efficacy is reported for patient groups according to doses received in the IT and LTE periods.

RESULTS

Of the 114 patients randomized in the IT period, 108 entered the LTE (n = 36 in each group); 93 received ADA 0·8 mg kg^-1 . Efficacy (≥ 75% improvement from baseline in Psoriasis Area and Severity Index) was maintained or improved from entry to the end of the LTE: MTX(IT)/ADA 0·8(LTE) 31-86% of patients; ADA 0·4(IT)/0·4 or 0·8(LTE) 28-47%; ADA 0·8(IT)/0·8(LTE) 50-72%. No serious infections occurred in the LTE.

CONCLUSIONS

After 52 weeks of long-term ADA treatment in children aged 4-18 years with severe plaque psoriasis, disease severity was reduced and maintained or further improved, as demonstrated by efficacy outcomes. No new safety risks were identified. What's already known about this topic? The results from the first three periods of this phase III trial in children aged 4-18 years with severe plaque psoriasis suggest that adalimumab is a safe and efficacious treatment option in this population. What does this study add? This is the first study to evaluate long-term treatment of adalimumab in children with severe psoriasis, and the first to evaluate switching from methotrexate to adalimumab in this population.

Switching to secukinumab in difficult-to-treat psoriasis recalcitrant to methotrexate, cyclosporine and leflunomide, in a tuberculosis-endemic country

Several biological agents have been approved for the treatment of recalcitrant psoriasis. However, there is a lack of a consensus algorithm guiding the drug selection for patients who have failed conventional drugs. In cases not improving with cyclosporine, direct switching to a biological therapy usually leads to a disease flare owing to increased production of interleukin (IL)-17A. Thus, secukinumab, a rapidly acting anti-IL-17A drug, may be ideal in such situations.

Persistence and effectiveness of nonbiologic systemic therapies for moderate-to-severe psoriasis in adults: a systematic review

Background

The persistence and effectiveness of systemic therapies for moderate‐to‐severe psoriasis in current clinical practice are poorly characterized.

Objectives

To systematically review observational studies investigating the persistence and effectiveness of acitretin, ciclosporin, fumaric acid esters (FAE) and methotrexate, involving at least 100 adult patients with moderate‐to‐severe psoriasis, exposed to therapy for ≥ 3 months.

Methods

MEDLINE, Embase, the Cochrane Library and PubMed were searched from 1 January 2007 to 1 November 2017 for observational studies reporting on persistence (therapy duration or the proportion of patients discontinuing therapy during follow‐up) or effectiveness [improvements in Psoriasis Area and Severity Index (PASI) or Physician's Global Assessment (PGA)]. This review was registered with PROSPERO, number CRD42018099771.

Results

Of 411 identified studies, eight involving 4624 patients with psoriasis were included. Variations in the definitions and analyses of persistence and effectiveness outcomes prevented a meta‐analysis from being conducted. One prospective multicentre study reported drug survival probabilities of 23% (ciclosporin), 42% (acitretin) and 50% (methotrexate) at 1 year. Effectiveness outcomes were not reported for either acitretin or ciclosporin. The persistence and effectiveness of FAE and methotrexate were better characterized, but mean discontinuation times ranged from 28 to 50 months for FAE and 7·7 to 22·3 months for methotrexate. At 12 months of follow‐up, three studies reported that 76% (FAE), 53% (methotrexate) and 59% (methotrexate) of patients achieved ≥ 75% reduction in PASI, and one reported that 76% of FAE‐exposed patients achieved a markedly improved or clear PGA.

Conclusions

The comparative persistence and effectiveness of acitretin, ciclosporin, FAE and methotrexate in real‐world clinical practice in the past decade cannot be well described due to the inconsistency of the methods used.

What's already known about this topic?

Research examining acitretin, ciclosporin, fumaric acid esters (FAE) and methotrexate for the treatment of moderate‐to‐severe psoriasis has focused on safety and efficacy in randomized controlled trials.

The persistence and effectiveness of acitretin, ciclosporin, FAE and methotrexate since the introduction of biologic therapies in real‐world clinical practice are poorly understood.

What does this study add?

This systematic review examines the persistence and effectiveness of methotrexate, acitretin, ciclosporin and FAE for moderate‐to‐severe psoriasis.

Data on the persistence and effectiveness of systemic therapies are lacking, particularly for acitretin and ciclosporin.

The definitions of persistence and reporting of effectiveness are inconsistent.

Further good‐quality observational studies are needed to explore the real‐world persistence and effectiveness of systemic treatments used for psoriasis.

Budget impact model of secukinumab for the treatment of moderate-to-severe psoriasis, psoriatic arthritis, and ankylosing spondylitis in Italy: a cross-indication initiative

Objective

Secukinumab, a fully human monoclonal IgG1 antibody that selectively neutralizes the proinflammatory cytokine IL-17A, has been approved in Europe in 2015 for the treatment of adult patients with moderate-to-severe plaque psoriasis, psoriatic arthritis (PsA), and ankylosing spondylitis (AS). This analysis assessed the budget impact of introduction of secukinumab to the Italian market for all three indications from the perspective of the Italian National Health Service.

Materials and methods

A cross-indication budget impact model was developed and included biologic-treated adult patients diagnosed with psoriasis, PsA, and AS. The analyses were conducted over a 3-year time horizon and included direct costs (drug therapy costs, administration costs, diseases-related costs, and adverse events costs). Model input parameters (epidemiology, market share projections, resource use, and costs) were obtained from the published literature and other Italian sources. The robustness of the results was tested via one-way sensitivity analyses: secukinumab cost, secukinumab market share, intravenous administration costs, and adverse events costs were varied by ±10%.

Results

The total patient population for secukinumab over the 3-year timeframe was projected to be 6,648 in the first year, increasing to 12,001 in the third year, for all three indications combined (psoriasis, PsA, and AS). Compared to a scenario without secukinumab in the market, the introduction of secukinumab in the market for the treatment of psoriasis, PsA, and AS showed a cumulative 3-year incremental budget impact of −5%, corresponding to savings of €66.1 million and per patient savings of about €1,855. The majority of the cost savings came from the adoption of secukinumab in AS (58%), followed by PsA (29%) and psoriasis (13%). Sensitivity analyses confirmed the robustness of the results.

Conclusion

Results from this cross-indication budget impact model show that secukinumab is a cost-saving option for the treatment of PsA, AS, and psoriasis patients in Italy.

Impact of previous biologic use on the efficacy and safety of brodalumab and ustekinumab in patients with moderate-to-severe plaque psoriasis: integrated analysis of the randomized controlled trials AMAGINE-2 and AMAGINE-3

BACKGROUND

Biologics are being used increasingly to treat moderate-to-severe psoriasis. Efficacy may differ in patients with previous exposure to biologics.

OBJECTIVES

To investigate the impact of previous biologic exposure on the efficacy and safety of brodalumab and ustekinumab in patients with moderate-to-severe plaque psoriasis.

METHODS

Two placebo- and ustekinumab-controlled phase III clinical trials. There was an initial 12-week induction phase where patients were treated with brodalumab [210 mg or 140 mg every 2 weeks (Q2W)], ustekinumab or placebo. Efficacy end points included ≥ 75% improvement in Psoriasis Area and Severity Index (PASI 75) and static Physician's Global Assessment (score of 0 or 1) vs. placebo, PASI 100 vs. ustekinumab, Dermatology Life Quality Index and Psoriasis Symptom Inventory. Adverse events were monitored throughout.

RESULTS

In total, 493 patients [334 (27%) brodalumab 210 mg Q2W and 159 (26%) ustekinumab] had received prior biologics; 150 (12%) and 62 (10%), respectively, reported previously failed treatment with a biologic. Brodalumab efficacy in patients with or without previous exposure to biologics was statistically equivalent: 40·9% and 39·5% of biologic-naive and -experienced patients achieved PASI 100 at week 12, compared with 21·1% and 17·0% with ustekinumab (both P < 0·001). In patients where prior biologics had been successful or failed, 41·7% and 32·0% achieved PASI 100, compared with 21·1% and 11·3% with ustekinumab. Tolerability was similar, and did not appear to be influenced by previous treatment with biologics.

CONCLUSIONS

The efficacy of brodalumab 210 mg Q2W was similar regardless of prior biological therapy (P = 0·31, 0·32 and 0·64 for PASI 75, 90 and 100, respectively). Almost twice as many patients achieved PASI 100 or complete clearance with brodalumab at week 12 compared with ustekinumab; the differences were most noticeable where previous biologics had failed. Both treatments were well tolerated.

The impact of psoriasis on professional life: PsoPRO, a French national survey

BACKGROUND

The physical, social and mental burden of psoriasis is well known, but its occupational impact has been less investigated.

OBJECTIVE

To assess the impact of psoriasis on the working life of patients compared with the general population.

METHODS

A national survey compared people with and without psoriasis using online questionnaires. In addition to the demographic, medical and professional characteristics, data on recent absenteeism and presenteeism were captured using the validated WPAI-PSO questionnaire.

RESULTS

The patient sample comprised 714 with psoriasis (PsO), including 81 treated with systemic therapies (PsoST), and 84 with associated psoriatic arthritis (PsO + PsA). The control sample comprised 604 active subjects representative of the French population. Compared to controls, the impact of the disease on working life was no greater in PsO patients. Conversely, unemployment within the past 5 years and mean number of sick leaves within the previous year were more frequent in PsO + PsA. In patients with active psoriasis skin lesions, all aspects of the WPAI questionnaire were negatively impacted in PsoST and PsO + PsA patients, but not in PsO patients: Levels of absenteeism were 3.3% in controls, 5.6% in PsO (NS), 8.3% in PsoST (P < 0.05) and 13.0% in Ps0 + PsA (P < 0.05); impairment in presenteeism reached 27.0%, 21.2% (NS), 43.5% (P < 0.05) and 53.2% (P < 0.05), respectively, while overall work impairment was 27.9%, 22.2% (NS), 46.3% (P < 0.05) and 57.6% (P < 0.05), respectively. Nevertheless, a higher proportion of PsoST and PsO + PsA patients reported that work was more important than any other activity in their life.

CONCLUSION

The occupational impact of psoriasis is important and significant in patients who receive systemic therapy or have concurrent PsA but minimal or absent in other psoriasis patients. The findings show that psoriasis patients have a high level of motivation to work.

Differential Drug Survival of Second-Line Biologic Therapies in Patients with Psoriasis: Observational Cohort Study from the British Association of Dermatologists Biologic Interventions Register (BADBIR)

Little is known about the drug survival of second-line biologic therapies for psoriasis in routine clinical practice. We assessed drug survival of second-line biologic therapies and estimated the risk of recurrent discontinuation due to adverse events or ineffectiveness in patients with psoriasis who had failed a first biologic therapy and switched to a second in a large, multicenter pharmacovigilance registry (n = 1,239; adalimumab, n = 538; etanercept, n = 104; ustekinumab, n = 597). The overall drug survival rate in the first year after switching was 77% (95% confidence interval = 74–79%), falling to 58% (55–61%) in the third year. Female sex, multiple comorbidities, concomitant therapy with cyclosporine, and a high Psoriasis Area and Severity Index at switching to the second-line biologic therapy were predictors of overall discontinuation (multivariable Cox proportional hazard model). Compared to adalimumab, patients receiving etanercept were more likely to discontinue therapy (hazard ratio = 1.87, 95% confidence interval = 1.24–2.83), whereas patients receiving ustekinumab were more likely to persist (hazard ratio = 0.46; 95% confidence interval = 0.33–0.64). Discontinuation of the first biologic therapy because of adverse events was associated with an increased rate of second drug discontinuation because of adverse events (hazard ratio = 2.55; 95% confidence interval = 1.50–4.32). In conclusion, drug survival rates differed among biologic therapies and decreased over time; second-line discontinuation because of adverse events was more common among those who discontinued first-line treatment for this reason. The results of this study should support clinical decision making when choosing second-line biologic therapy for patients with psoriasis.

Comparative effectiveness of biological therapies on improvements in quality of life in patients with psoriasis

Background

Evidence of the comparative effectiveness of biological therapies for psoriasis on health‐related quality of life (HRQoL) in routine clinical practice is limited.

Objectives

To examine the comparative effectiveness of adalimumab, etanercept and ustekinumab on HRQoL in patients with psoriasis, and to identify potential predictors for improved HRQoL.

Methods

This was a prospective cohort study in which changes in HRQoL were assessed using the Dermatology Life Quality Index (DLQI) and EuroQoL‐5D (EQ‐5D) at 6 and 12 months. Multivariable regression models were developed to identify factors associated with achieving a DLQI of 0/1 and improvements in the EQ‐5D utility score.

Results

In total, 2152 patients with psoriasis were included, with 1239 patients on adalimumab, 517 on etanercept and 396 on ustekinumab; 81% were biologic naïve. For the entire cohort, the median (interquartile range) DLQI and EQ‐5D improved from 18 (13–24) and 0·73 (0·69–0·80) at baseline to 2 (0–7) and 0·85 (0·69–1·00) at 6 months, respectively (P < 0·001). Similar improvements were achieved at 12 months. At 12 months, multivariable regression modelling showed that female sex, multiple comorbidities, smoking and a higher DLQI or a lower EQ‐5D utility score at baseline predicted a lower likelihood of achieving a DLQI of 0/1 or improvement in the EQ‐5D. Compared with adalimumab, patients receiving etanercept, but not ustekinumab, were less likely to achieve a DLQI of 0/1. There was no significant difference between the biological therapies in EQ‐5D improvement.

Conclusions

In routine clinical practice biological therapies produce marked improvement in HRQoL, which is influenced by the choice of biological therapy, baseline impairment in HRQoL, lifestyle characteristics and comorbidities. These findings should help inform selection of optimal biological therapy for patients related to improvements in HRQoL.

What's already known about this topic?

Evidence of the comparative effectiveness of biological therapies for psoriasis on health‐related quality of life (HRQoL) in routine clinical practice is limited.

Earlier observational studies were either cross‐sectional, thereby limiting the ability to compare changes in HRQoL, or cohort studies that have not taken into account important clinical factors that could influence treatment response, such as alterations in dosing regimens of biological therapies and the concomitant use of conventional systemic treatments for psoriasis.

What does this study add?

This large prospective cohort study found that in routine clinical practice, the use of biological therapies for psoriasis was associated with marked improvements in HRQoL over 12 months.

These improvements were influenced by the choice of biological therapy, baseline impairment in HRQoL, lifestyle characteristics and comorbidities.

Compared with adalimumab, patients receiving etanercept were less likely to achieve a DLQI of 0/1, but there was no significant difference between ustekinumab and adalimumab in the proportion of patients achieving a DLQI of 0/1.

There was no significant difference between the three biological therapies in level of improvement in the EQ‐5D.

Sustained Psoriasis Area and Severity Index, Dermatology Life Quality Index and EuroQol-5D response of biological treatment in psoriasis: 10 years of real-world data in the Swedish National Psoriasis Register

BACKGROUND

Few studies have analysed the long-term effects of biological treatment in psoriasis. PsoReg, the Swedish national register for systemic psoriasis treatment, started in 2006 and now includes 10 years of real-world data on the effectiveness of biological treatment.

OBJECTIVES

To analyse the long-term real-world outcome data of patients who are biologically naïve with moderate-to-severe psoriasis after switching to biological treatment.

METHODS

An observational study of patients who are biologically naïve with at least one registration of outcome before switching to biological treatment while included in PsoReg and at least one follow-up visit. Psoriasis Area and Severity Index (PASI), Dermatology Life Quality Index (DLQI) and EuroQol-5D (EQ-5D) values were analysed at 3-5 months, 6-11 months and at least once after ≥ 1 year, up to 9 years after the switch to biological treatment.

RESULTS

In total, 583 patients fulfilled the inclusion criteria. Of these, 399, 395 and 373 patients had observed outcome data beyond 1 year on the PASI, DLQI and EQ-5D, respectively, and 164, 168 and 152, respectively, were observed in at least three time periods after the switch. Significant (P < 0·01) improvement in PASI, DLQI and EQ-5D scores was observed 3-5 months after the switch and sustained under the whole observation period. The mean PASI, DLQI and EQ-5D changed from 13·5 ± 9·1, 9·0 ± 8·1 and 0·74 ± 0·22, respectively, before the switch, to 4·0 ± 3·5, 3·7 ± 4·7 and 0·79 ± 0·21, respectively, 1-5 years after the switch.

CONCLUSIONS

Biological treatment, as used in clinical practice, shows a stable long-term effectiveness in all the measured dimensions, PASI, DLQI and EQ-5D.

Regional Differences in the Prescription of Biologics for Psoriasis in Sweden: A Register-Based Study of 4168 Patients

BACKGROUND

Observational studies suggest an inequitable prescription of biologics in psoriasis care, which may be attributed to geographical differences in treatment access. Sweden regularly ranks high in international comparisons of equitable healthcare, and is, in connection with established national registries, an ideal country to investigate potential inequitable access.

OBJECTIVE

The aim was to determine whether the opportunity for patients to receive biologics depends on where they receive care.

METHODS

Biologic-naïve patients enrolled in the Swedish National Register for Systemic Treatment of Psoriasis (PsoReg) from 2008 to 2015 (n = 4168) were included. The association between the likelihood of initiating a biologic and the region where patients received care was analyzed. The strength of the association was adjusted for patient and clinical characteristics, as well as disease severity using logistic regression analysis. The proportion of patients that switched to a biologic (switch rate) and the probability of switch to a biologic was calculated in 2-year periods.

RESULTS

The national switch rate increased marginally over time from 9.7 to 11.0%, though the uptake varied across regions. Adjusted odds ratios for at least one region were significantly different from the reference region in every 2-year period. During the latest period (2014-2015), the average patient in the lowest prescribing region was nearly 2.5 times less likely to switch as a similar patient in the highest prescribing region.

CONCLUSIONS

Geographical differences in biologics prescription persist after adjusting for patient characteristics and disease severity. The Swedish example calls for further improvements in delivering equitable psoriasis care.

EQ-5D health utilities: exploring ways to improve upon responsiveness in psoriasis

AIMS

To determine if EuroQoL 5-Dimension Health Questionnaire (EQ-5D) health utility scores were able to discriminate among different levels of improvement in psoriasis severity following therapy.

MATERIALS AND METHODS

Data were from three placebo-controlled phase 3 ixekizumab studies (UNCOVER-1, UNCOVER-2, and UNCOVER-3) with patients who had baseline Dermatology Life Quality Index scores >10 (DLQI >10). Psoriasis severity (Psoriasis Area and Severity Index [PASI]), general health utility (EQ-5D), and psoriasis-specific utility (EQ-PSO, UNCOVER-3 only) were assessed. EQ-5D-5L utility scores were generated using the England EQ-5D-5L value set, a crosswalk applied to the EQ-5D-3L United States (US) and United Kingdom (UK) value sets, and a regression-based exploratory scoring function for the EQ-PSO (UK). Analysis of variance was used to estimate change in EQ-5D-5L from baseline to Week 12 per PASI improvement level: PASI <50, PASI 50 to <75, PASI 75 to <90, PASI 90 to <100, and PASI 100. Missing data were imputed using the last observation carried forward method. Value sets for the UK, England, and the US were applied.

RESULTS

In total, 2085 patients across UNCOVER-1, UNCOVER-2, and UNCOVER-3 had baseline DLQI >10 and available utility scores. At Week 12, mean EQ-5D utility scores increased with increasing PASI improvement levels (p < 0.001, all analyses). Mean health utilities for PASI 90 to <100 and PASI 100 were similar when based on the generic classifier, whereas a clear differentiation between PASI 90 to <100 and PASI 100 was observed for EQ-PSO mean scores (UNCOVER-3 only, n = 645; PASI 90 to <100: 0.141, PASI 100: 0.200; adjusted p = 0.043).

LIMITATIONS

EQ-5D-5L index-based scores have limited ability to differentiate among psoriasis patients at the highest PASI improvement levels. ConclusionsL Adding psoriasis-specific EQ-PSO dimensions to the EQ-5D may enhance responsiveness to improvement in skin clarity at the highest PASI levels, and, therefore, generate utility scores that better reflect treatment benefit in cost-utility models.

Healthcare Provider Type and Switch to Biologics in Psoriasis: Evidence from Real-World Practice

BACKGROUND

Previous research indicates an uneven uptake of biologics in patients with moderate-to-severe psoriasis in Sweden. Therefore, it is essential to scrutinise variations in treatment patterns.

OBJECTIVE

The aim of this study was to evaluate the extent to which the uptake of biologics for psoriasis differs between types of healthcare provider.

METHODS

Three types of provider were identified within 52 units participating in the Swedish National Registry for Systemic Psoriasis Treatment (PsoReg): university hospitals, non-university hospitals and individual practices. Biologics-naïve patients (n = 3165) were included in analyses to investigate the probability of switch to biologics. The numbers of patients fulfilling the criteria for moderate-to-severe psoriasis [Psoriasis Area and Severity Index (PASI) ≥10 and Dermatology Life Quality Index (DLQI) ≥10] among patients who switched to biologics and patients who did not switch were reported. A logistic regression model was used to calculate how healthcare provider type influenced the probability of switch to biologics whilst adjusting for patient characteristics and disease severity.

RESULTS

During registration, 16% of patients switched to biologics while 84% remained on conventional systemic treatment. In 7% of patients, the criteria PASI ≥10 and DLQI ≥10 was fulfilled at their last visit without switching to biologics, whereas in 10% of patients the criteria was not fulfilled prior to switch. After controlling for patient characteristics and disease severity, small or no difference in the probability of switch was observed between provider types.

CONCLUSIONS

Disease severity does not explain the decision to switch or not to switch to biologics for a disproportionate number of patients. There seems to be an uneven uptake of biologics in Swedish clinical practice, but the type of healthcare provider cannot explain this variation. More research is needed on what factors influence the prescription of biologics.

Health-related quality of life in patients with psoriasis: a systematic review of the European literature

PURPOSE

To summarize the data published over the last 5 years in the European Union related to the health-related quality of life (HRQoL) of patients with psoriasis and its conditioning factors.

METHODS

International electronic databases and gray literature were searched to identify studies conducted on patient-reported outcomes in patients with psoriasis, published in Europe between January 1, 2009 and December 31, 2013. Bibliographic references were hand-searched. Editorials, letters, commentaries, opinion papers, and studies related to specific treatments were excluded.

RESULTS

A total of 46 studies met the inclusion criteria, 27 of them reporting data related to HRQoL or its conditioning factors. The publications reviewed highlighted the substantial negative impact of psoriasis on patients' HRQoL. Most of the studies that analyzed the relationship between HRQoL and sociodemographic characteristics described a relation between gender (female) and age (young patients) and poorer HRQoL. An association between HRQoL impairment and visibility of skin lesions and disease activity and severity was also established. Skin discomfort and pruritus were identified as elements that negatively influenced HRQoL. Use of biological agents had a positive impact on HRQoL and on treatment satisfaction, a better HRQoL being seen in patients treated with systemic therapies and biologics.

CONCLUSIONS

HRQoL has been broadly addressed in patients with psoriasis in Europe. Several disease- and patient-related factors contributed to its deterioration. Therapeutic measures with proven effectiveness in controlling disease symptoms and reducing PASI should be considered in patients with a severe disease who have a poorer HRQoL.

Quality of life and patient benefit following transition from methotrexate to ustekinumab in psoriasis

BACKGROUND

TRANSIT (NCT01059773) compared immediate and gradual transition from methotrexate to ustekinumab in psoriasis patients via multiple measures, including patient-reported outcomes.

OBJECTIVE

To evaluate patient perception of treatment benefits in TRANSIT.

METHODS

A total of 489 psoriasis patients received ustekinumab, with immediate cessation of methotrexate (Arm 1) or 4 weeks' overlap with decreasing methotrexate dose (Arm 2). Ustekinumab was administered at weeks 0, 4, 16, 28 and 40. Dermatology Life Quality Index (DLQI), EuroQol 5-item (EQ-5D), visual analogue scale (VAS) valuation technique and patient benefit index (PBI) were employed. Mean global PBI and sub-scores were calculated from the sum of the benefit items weighted by their respective relevance at baseline. Patient-relevant benefit was defined as PBI ≥1 (scale: 0 [no benefit] to 4 [maximum benefit]). Correlations of global PBI with Psoriasis Area and Severity Index (PASI) and DLQI were examined.

RESULTS

Relationships between PBI and clinical data were evaluable in 340 patients. The most important treatment goals at baseline included: 'be healed of all skin defects', 'have confidence in therapy', 'get better skin quickly' and 'regain control of the disease'. Benefit in PBI global score was achieved at week 4 by 93% of patients in Arm 1 and 91% in Arm 2. Global PBI scores increased in both Arms between weeks 4 and 52. Global PBI correlated weakly with PASI change from baseline (correlation coefficient range: -0.22 to -0.40), and moderately with DLQI (-0.29 to -0.54). Overall DLQI score was lower than baseline at all times; and the percentage of patients with an overall score of 0 or 1 increased with time. Correspondingly, EQ VAS scores increased with time. DLQI and EQ VAS results were similar between arms.

CONCLUSIONS

Regardless of the strategy for transitioning from methotrexate, ustekinumab was associated with rapid and sustained improvement in patient-reported outcomes. PBI appears a suitable tool for assessing patient-relevant treatment benefits in psoriasis patients.

Patient-reported outcomes in the Swedish National Quality Registers

Patient-reported outcomes (PROs) are important in the healthcare system to gain understanding of patients' views on the effects of a treatment. There is an abundance of available patient-reported outcome measures (PROMs), both disease specific and generic. In the Swedish healthcare system, the national quality registers are obliged to incorporate PROs for certification at a high level. A review of the latest annual applications for funding (n = 108) shows that at present, 93 national quality registers include some form of PROM or patient-reported experience measure (PREM). Half of the registers include some type of generic measure, more than half include disease/symptom-specific measures, and around 40% include PREMs. Several different measures and combinations of measures are used, the most common of which are the EQ-5D, followed by the SF-36/RAND-36. About one-fifth of the registers report examples of how patient-reported data are used for local quality improvement. These examples include enhancing shared decision-making in clinical encounters (most common), as a basis for care plans, clinical decision aids and treatment guidelines, to improve the precision of indications for surgery (patient and healthcare professional assessments may differ), to monitor complications after the patient has left hospital and to improve patient information. In addition, funding applications reveal that most registers plan to extend their array of PROMs and PREMs in future, and to increase their use of patient-reported data as a basis for quality improvement.

Providing Guidance for Patients With Moderate-to-Severe Psoriasis Who Are Candidates for Biologic Therapy

Psoriasis is a chronic, immune-mediated disease characterized by itchy, scaly, and often painful plaques in the skin. Psoriasis can have significant psychosocial burdens and increased risks for numerous comorbidities, including diabetes, hypertension, and cardiovascular disease, particularly in patients with moderate-to-severe disease. Dermatology nurse practitioners and physician assistants are an important part of the healthcare team, contributing to all aspects of psoriasis management. This review reinforces the unique aspects of care that nurse practitioners and physician assistants provide to patients with psoriasis, such as facilitating conversations about managing disease, setting appropriate expectations, and considering treatment options, including when treatment response or tolerability is suboptimal. The importance of relationship building is stressed. Patient management topics discussed include helpful tips about assessing treatment options, initiating biologic therapy, optimizing patient adherence, and managing comorbidities. Also reviewed are how to deal with common barriers including lack of knowledge about psoriasis or making healthy lifestyle changes, fear of injections or side effect risks, lack of health insurance, and concerns about treatment costs. Overall, by forming meaningful relationships and engaging patients in their psoriasis care, nurse practitioners and physician assistants can help to optimize clinical efficacy outcomes and consistently manage moderate-to-severe psoriasis and its comorbidities over the patient’s life course.

Secukinumab treatment of plaque psoriasis shows early improvement in DLQI response - results of a phase II regimen-finding trial

BACKGROUND

The social stigma and chronicity of psoriasis significantly affect health-related quality of life (HRQoL).

OBJECTIVE

We examined the effect of three regimens of secukinumab on HRQoL in moderate to severe psoriasis patients.

METHODS

Twelve-week data from a phase II, randomized, double-blind, placebo-controlled, regimen-finding study evaluated HRQoL, measured by the Dermatology Life Quality Index (DLQI). Secukinumab or placebo was administered subcutaneously in three treatment regimens: single (baseline only), monthly (baseline, weeks 4, 8) and early (baseline, weeks 1, 2, 4). Differences among regimens were assessed with logistic regression models and Fisher's exact test.

RESULTS

Patients (n = 404) were randomized to single (baseline) treatment regimen, n = 66; monthly, (baseline, weeks 4 and 8), n = 138; early, (baseline, weeks 1, 2, 4), n = 133; and placebo, n = 67. DLQI response was significantly higher in early, monthly and single regimens than in placebo regimen (40.8%, 33.6% and 13.1% vs. 1.6%, respectively; P < 0.001 for all).

CONCLUSION

Moderate to severe psoriasis patients receiving monthly and early treatment with secukinumab demonstrated improved HRQoL compared with placebo.

A patient-centred approach to biological treatment decision making for psoriasis: an expert consensus

Background

Each individual psoriasis patient has different expectations and goals for biological treatment, which may differ from those of the clinician. As such, a patient‐centred approach to treatment goals remains an unmet need in psoriasis.

Objective

The aim of this study was to review available data on patients’ and physicians’ decision criteria and expectations of biological treatment for moderate‐to‐severe psoriasis with the aim of developing a core set of questions for clinicians to ask patients routinely to understand what is important to them and thus better align physicians’ and patients’ expectations of treatment with biologics and its outcomes.

Methods

A literature search was conducted to identify key themes and data gaps. Aspects of treatment relevant when choosing a biological agent for an individual patient were identified and compared to an existing validated instrument. A series of questions aimed at helping the physician to identify the particular aspects of treatment that are recognised as important to individual psoriasis patients was developed.

Results

Key findings of the literature search were grouped under themes of adherence, decision‐making, quality of life, patient/physician goals, communication, patient‐reported outcomes, satisfaction and patient benefit index. Several aspects of treatment were identified as being relevant when choosing a biological agent for an individual patient.

The questionnaire is devised in two parts. The first part asks questions about patients’ experience of psoriasis and satisfaction with previous treatments. The second part aims to identify the treatment attributes patients consider to be important and may as such affect their preference for a particular biological treatment. The questionnaire results will allow the physician to understand the key factors that can be influenced by biological drug choice that are of importance to the patient. This information can be used be the physician in clinical decision making.

Conclusion

The questionnaire has been developed to provide a new tool to better understand and align patients’ and physicians’ preferences and goals for biological treatment of psoriasis.

An evolution in switching therapy for psoriasis patients who fail to meet treatment goals

Switching psoriasis treatment is a common, accepted practice that is used to improve disease management and improve patient outcomes (e.g., when patients are experiencing suboptimal efficacy and/or tolerability with a given therapy). Historically, switching treatment was often performed to limit patients’ cumulative exposure to conventional systemic agents (e.g., methotrexate, cyclosporine) with the goal of reducing end‐organ toxicity. However, the practice of switching treatments has evolved in recent years with the availability of highly effective and tolerable biologic agents. In current practice, near‐complete skin clearance with minimal side effects should be a realistic treatment goal for most patients with moderate‐to‐severe psoriasis, and consideration for switching therapies has shifted to become more focused on achieving maximum possible skin clearance, enhanced quality of life, and improved patient satisfaction. This review provides a discussion of recent guidance on switching psoriasis therapies, including initial considerations for when switching therapy may be advisable and challenges associated with switching therapy, along with an overview of published clinical studies evaluating outcomes associated with switching therapy. The goal of this review is to empower dermatologists to optimally manage their patients’ psoriasis by providing the tools needed to develop rational strategies for switching treatments based on the pharmacologic characteristics of available treatments and each patient's clinical needs and treatment preferences.

A systematic literature review to compare quality of life in psoriasis with other chronic diseases using EQ-5D-derived utility values

BACKGROUND

Psoriasis is a chronic, immune-mediated dermatological disease associated with substantial economic, clinical, and humanistic burden.

OBJECTIVE

The aim of this study was to understand the disutility of patients with psoriasis vulgaris, using mean baseline EuroQoL five dimensions (EQ-5D) index scores reported in the published literature, and to compare this to patients with other chronic diseases.

METHODS

Two systematic literature searches were conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Searches were conducted in ten databases including Embase, MEDLINE, and the Cochrane Central Register of Controlled Trials (CENTRAL). The first search (December 2013) used search terms psoria* AND (EQ5D OR EQ OR EUROQoL). Only publications of original research, which reported baseline EQ-5D scores for mild/moderate/severe psoriasis, were included. The second search (March 2014) used the terms (systematic review) AND (EQ5D OR EQ 5D OR EuroQoL). Titles were screened by two independent reviewers. Four independent reviewers reviewed titles and full-length papers. EQ-5D scores for psoriasis patients were qualitatively compared with scores from patients with other chronic diseases identified through the literature search.

RESULTS

Of 133 publications on psoriasis, 12 met the inclusion criteria. The mean EQ-5D index scores for psoriasis (all severities) ranged from 0.52 (standard deviation: 0.39) to 0.9 (standard deviation: 0.1). Of the 48 results from the second search, six met the inclusion criteria. The reported EQ-5D lower limit for other diseases ranged from 0.20 (Type 2 diabetes mellitus) to 0.66 (liver diseases). The highest EQ-5D estimates for other diseases ranged from 0.79 (liver diseases) to 0.93 (cancer patients). Both lower and upper EQ-5D estimates in psoriasis patients were within the range of those reported for other chronic diseases.

CONCLUSION

Comparative studies of morbidity are relevant in health care studies and patient advocacy. This systematic review demonstrates that the ranges of disutility among psoriasis patients are within the ranges of other chronic diseases (cardiovascular diseases, diabetes, end-stage renal diseases, liver diseases, cancer, and visual disorders).

Real-world outcome analysis of continuously and intermittently treated patients with moderate to severe psoriasis after switching to a biologic agent

BACKGROUND

Clinical studies of continuous versus intermittent biologic therapy for moderate to severe psoriasis demonstrate improved efficacy with continuous treatment.

OBJECTIVE

To analyse Swedish real-world data of continuously and intermittently treated biologic-naïve patients after switching to a biologic agent.

METHODS

This is an observational study based on PsoReg, the Swedish registry for systemic psoriasis treatment. Outcome effects in biologic-naïve patients who switched to a biologic agent (n = 351) were analysed in groups of continuous, intermittent and terminated treatment.

RESULTS

Intermittently treated patients (n = 50) reported higher Psoriasis Area and Severity Index and Dermatology Life Quality Index values after switching than patients with continuous (n = 260) or terminated treatment (n = 41).

STUDY LIMITATIONS

The reason for intermittent treatment was not recorded. The intermittently treated patients may be a heterogeneous group and a limitation is that it cannot be determined whether less than continuous use was offered to handle negative aspects.

CONCLUSION

Patients with continuous biologic treatment tend to achieve better outcomes compared to intermittently treated patients.

Improvements in patient-reported outcomes in patients with psoriasis receiving etanercept plus topical therapies: results from REFINE

Background

The REFINE study examined the efficacy and safety of adding topical corticosteroid therapy to etanercept when stepping down from the initial dose of etanercept to the maintenance dose. Clinical responses were shown to be similar in patients who remained on etanercept 50 mg twice weekly (BIW) and those who received etanercept 50 mg once weekly (QW) plus topical therapies through week 24.

Objective

The purpose of this analysis was to evaluate the effect of treatment on health‐related quality of life (HRQoL) for patients in REFINE.

Methods

All patients received etanercept 50 mg BIW for 12 weeks and were then randomized to etanercept 50 mg BIW or etanercept 50 mg QW plus topical corticosteroid as required to clear through week 24. HRQoL measures included the Dermatology Life Quality Index (DLQI), Treatment Satisfaction Questionnaire for Medication (TSQM) and the Economic Implications of Psoriasis Patient Questionnaire. No comparative testing was performed for this descriptive analysis. Missing data were imputed using the last observation carried forward.

Results

For 287 randomized patients (144 etanercept; 143 etanercept plus topical), the mean change [standard deviation (SD)] in DLQI from baseline to week 24 was 10.7 (7.8) for etanercept and 9.9 (6.9) for etanercept plus topical. Mean change (SD) in TSQM effectiveness, convenience, side‐effects and global satisfaction was 27.1 (36.1), 14.8 (25.9), −0.7 (22.0) and 26.7 (32.5) for the etanercept arm and 32.5 (40.3), 18.5 (29.0), 1.3 (19.4) and 28.4 (35.9) for etanercept plus topical. Economic implications, including healthcare visits, employment status, work productivity, ability to perform daily activities and out‐of‐pocket expenses were similar between treatment arms.

Conclusion

At week 24 of REFINE, measures of HRQoL were numerically similar in patients who stayed on etanercept 50 mg BIW and patients who received etanercept 50 mg QW plus topical therapies.

Review of 103 Swedish Healthcare Quality Registries

BACKGROUND AND OBJECTIVES

In the past two decades, an increasing number of nationwide, Swedish Healthcare Quality Registries (QRs) focusing on specific disorders have been initiated, mostly by physicians. Here, we describe the purpose, organization, variables, coverage and completeness of 103 Swedish QRs.

METHODS

From March to September 2013, we examined the 2012 applications of 103 QRs to the Swedish Association of Local Authorities and Regions (SALAR) and also studied the annual reports from the same QRs. After initial data abstraction, the coordinator of each QR was contacted at least twice between June and October 2013 and asked to confirm the accuracy of the data retrieved from the applications and reports.

RESULTS

About 60% of the QRs covered ≥80% of their target population (completeness). Data recorded in Swedish QRs include aspects of disease management (diagnosis, clinical characteristics, treatment and lead times). In addition, some QRs retrieve data on self-reported quality of life (EQ5D, SF-36 and disease-specific measures), lifestyle (smoking) and general health status (World Health Organization performance status, body mass index and blood pressure).

CONCLUSION

Detailed clinical data available in Swedish QRs complement information from government-administered registries and provide an important source not only for assessment and development of quality of care but also for research.

Moderate to severe psoriasis patients' subjective future expectations regarding health-related quality of life and longevity

BACKGROUND

Unrealistic expectations regarding treatments and clinical outcomes may lead to disappointment about therapy and sub-optimal compliance; nonetheless, these expectations have not been studied in psoriasis patients yet.

OBJECTIVE

To evaluate psoriasis patients' subjective future expectations regarding health-related quality of life (HRQOL) and life expectancy, and to explore clinical features associated with under- or overestimating behaviour.

METHODS

A cross-sectional questionnaire survey of consecutive adult patients with moderate to severe psoriasis was conducted. HRQOL expectations were recorded by applying the EQ-5D descriptive system for 6 months ahead and for future ages of 60, 70, 80 and 90 respectively.

RESULTS

In total, 167 patients (71% males) were included in the analysis with mean age of 50.4 ± 12.4 years and mean EQ-5D score of 0.71 ± 0.30. Overall 65% had chronic plaque psoriasis, 35% nail psoriasis, 35% scalp involvement, 29% psoriatic arthritis, 9% inverse psoriasis and 5% palmoplantar psoriasis respectively (combinations occurred). Participants expected 0.1 ± 0.23 mean improvement in EQ-5D within 6 months (P < 0.001) that achieves the minimum clinically important difference. Overall 37% expected improvement and 13% decline; however, 49% expected no changes in any of the five dimensions of EQ-5D within 6 months. Female gender, inverse or palmoplantar involvement and more severe psoriasis were likely associated with higher expectations. Patients at the initiation of their first biological at the time of the survey expected 0.18 ± 0.24 increase that seems to be realistic compared to the EQ-5D utility gain achieved in randomized controlled trials. Males expected by 2.7 ± 11.1 more, while females expected by 5.2 ± 9.3 less life years compared to the average statistical gender- and age-matched life expectancy (P < 0.05). Patients who expected to be alive at ages of 60, 70, 80 and 90 scored their future EQ-5D at ages of 60 to 90: 0.59 ± 0.46, 0.48 ± 0.41, 0.42 ± 0.41 and 0.22 ± 0.47 respectively.

CONCLUSION

Our findings highlight the importance of exploring expectations that might help to increase patients' compliance.
