An international multi-centre analysis of current prescribing practices and shared decision-making in psoriatic arthritis.

OBJECTIVES: Shared decision-making (SDM) is advocated to improve patient outcomes in Psoriatic arthritis (PsA). We analysed current prescribing practices and the extent of SDM in PsA across Europe. METHODS: The ASSIST study was a cross-sectional observational study of PsA patients aged ≥18 years attending face-to-face appointments between July 2021-March 2022. Patient demographics, current treatment and treatment decisions were recorded. SDM was measured by the clinician's effort to collaborate (CollaboRATE questionnaire) and patient communication confidence (PEPPI-5 tool). RESULTS: 503 patients were included from 24 centres across the UK, France, Germany, Italy and Spain. Physician- and patient-reported measures of disease activity were highest in the UK. Conventional synthetic DMARDs constituted a higher percentage of current PsA treatment in UK than continental Europe (66.4% vs 44.9%), which differed from biologic DMARDs (36.4% vs 64.4%). Implementing treatment escalation was most common in the UK. CollaboRATE and PEPPI-5 scores were high across centres. Of 31 patients with low CollaboRATE scores (<4.5), no patients with low PsAID-12 scores (<5) had treatment escalation. However, of 465 patients with CollaboRATE scores ≥4.5, 59 patients with low PsAID-12 scores received treatment escalation. CONCLUSIONS: Higher rates of treatment escalation seen in the UK may be explained by higher disease activity and a younger cohort. High levels of collaboration in face-to-face PsA consultations suggests effective implementation of the SDM approach. Our data indicate that, in patients with mild disease activity, only those with higher perceived collaboration underwent treatment escalation. Prospective studies should examine the impact of SDM on PsA patient outcomes. TRIAL REGISTRATION: clinicaltrials.gov, NCT05171270.

Validation of the Psoriatic Arthritis Impact of Disease (PsAID) Questionnaire and its potential as a single-item outcome measure in clinical practice.

OBJECTIVES: The Psoriatic Arthritis Impact of Disease (PsAID) Questionnaire is a recently developed patient-reported outcome measure (PROM) of disease impact in psoriatic arthritis (PsA). We set out to assess the validity in an independent cohort of patients, estimate the minimally important difference for improvement and explore the potential of individual components of the PsAID in clinical practice. METHODS: Data were collected prospectively for a single-centre cohort of patients with PsA. Construct validity was assessed by Spearman correlation with other PROMs and reliability by intraclass correlation coefficient (ICC) at 1 week. Sensitivity to change at 3 months was determined by the standardised response mean (SRM) in those patients with active disease requiring a change in treatment. RESULTS: A total of 129 patients (mean ±SD age 52.1±13.3, 57% women, disease duration 10.2±8 years) completed the baseline questionnaires and assessments. The mean baseline PsAID12 score was 3.92±2.26 with an ICC of 0.91 (95%CI 0.87 to 0.94). The SE of measurement was 0.51 and the minimal detectable change was 1.41. There was strong correlation (r≥0.70) with most of the PROMs studied and moderate correlation with clinical outcomes (r=0.40-0.57). The SRM of the PsAID12 was 0.74 (95%CI 0.45 to 0.97). There was strong correlation with individual PsAID items and their corresponding PROM questionnaires (r≥0.67). CONCLUSION: The PsAID is a reliable, feasible and discriminative measure in patients with PsA. The good responsiveness of the PsAID and strong correlation of individual items with other PROMS represent an opportunity to reduce questionnaire burden for patients in studies and clinical practice.

Patients' perspectives of telemedicine appointments for psoriatic arthritis during the COVID-19 pandemic: results of a patient-driven pilot survey.

BACKGROUND: Over recent years the lack of patient involvement in the design, set-up and implementation of clinical research studies has been well recognised; as such there has been a drive within research communities to increase patient participation. Patient perspectives on telemedicine differ widely, with variation in whether patients feel remote consultations are beneficial. By means of a patient-driven survey, we aimed to formally evaluate patient perspectives on its benefits and pitfalls, focusing on patients with psoriatic arthritis (PsA). METHODS: An e-survey was developed by two patient representatives on the BritPACT steering committee, with a view to determining unmet needs and the perceived impact on clinical care of virtual consultations amongst patients with PsA. RESULTS: 128 patients responded to the e-survey. 109 patients rated the effectiveness of their telemedicine appointment and, of these, 18% felt their virtual consultation was very/extremely effective compared to an in-clinic consultation and 49% felt it was somewhat/equally as effective; furthermore, 48% (51/107) felt that such virtual consultations would be of benefit to them after the pandemic. 36% of respondents felt their virtual consultation was not as effective as an in-clinic review. Themes identified from open-ended questions included the lack of visual cues, lack of physical examination and effect on rapport and ease of open communication as the main pitfalls of virtual consultations. Patients with well-controlled symptoms appeared more satisfied with remote reviews compared to those with active disease, though on the whole respondents recognised the benefits, such as saving travel time and costs. Those who had an established relationship with their health professional appeared less concerned regarding virtual consultations though a recurring view was that newly diagnosed patients should have in-clinic appointments to build rapport and improve symptom control at an early stage. CONCLUSIONS: Overall patients' perspectives on virtual consultations varied widely though patients with well-controlled symptoms and those who had a previously established relationship with their healthcare professionals and well-controlled disease appeared more satisfied with remote reviews.

A Multicenter Nominal Group Study to Rank Outcomes Important to Patients, and Their Representation in Existing Composite Outcome Measures for Psoriatic Arthritis.

OBJECTIVE: To rank outcomes identified as important to patients with psoriatic arthritis (PsA) and examine their representation in existing composite measures. METHODS: Seven nominal group technique (NGT) meetings took place at 4 hospital sites. Two sorting rounds were conducted to generate a shortlist of outcomes followed by a group discussion and final ranking. In the final ranking round, patients were given 15 points each and asked to rank their top 5 outcomes from the shortlist. The totals were summed across the 7 NGT groups and were presented as a percentage of the maximum possible priority score. RESULTS: Thirty-one patients took part: 16 men and 15 women; the mean age was 54 years (range 24-77; SD 12.2), the mean disease duration was 10.3 years (range 1-40; SD 9.2), and mean Health Assessment Questionnaire was 1.15 (range 0-2.63; SD 0.7). The highest-ranked outcomes that patients wished to see from treatment were pain with 93 points (20.0%), fatigue 62 (13.3%), physical fitness 33 (7.1%), halting/slowing damage 32 (6.9%), and quality of life/well-being 29 (6.2%). Reviewing existing composite measures for PsA demonstrated that no single measure adequately identifies all these outcomes. CONCLUSION: Pain and fatigue were ranked as the outcomes most important to patients receiving treatment for PsA and are not well represented within existing composite measures. Future work will focus on validating composite measures modified to identify outcomes important to patients.

Development of a Flare Instrument for Use in Psoriatic Disease: A Report from the 2015 GRAPPA Annual Meeting.

OBJECTIVE: The objective of this Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) initiative is to develop a questionnaire to determine the presence of a flare of disease activity in psoriatic disease (PsD), for use in clinical care and research settings. METHODS: In 2014 and 2015, 2 online Delphi surveys of patients and physicians attempted to achieve consensus about items that might discriminate a flare of disease. In the first round, items were derived from previous qualitative studies with patients; in the second round, new items, suggested by both patients and physicians, were added. Survey results were discussed at the 2015 GRAPPA annual meeting, and 8 breakout groups discussed specific aspects of PsD flares. RESULTS: Survey participants were patients (n = 103 and n = 57 in rounds 1 and 2) and physicians (n = 125 and n = 81). Items for flare covered 6 domains (joints, skin, emotion, participation, fatigue, and unclassified). Patients agreed that 20 items were important (10 joints, 1 participation, 8 fatigue, 1 unclassified), and physicians agreed on 23 items (5 skin, 11 joints, 4 participation, 3 unclassified). Eight items were selected as important by both groups: 7 joint items and 1 unclassified. Patients emphasized fatigue and physicians emphasized skin and participation. Breakout groups concluded that the components of a flare instrument should be derived from patients. A flare should be defined as a change in disease state requiring intervention. CONCLUSION: The concept of flare in PsD covers articular, skin, emotional, participation, and fatigue domains. Further work is required to specify items that represent these domains.
