Treatment satisfaction in patients with hidradenitis suppurativa: A real-world survey from the EU5 and US.

Introduction Hidradenitis suppurativa (HS) is a debilitating, inflammatory skin disorder. Treatment strategies in patients with HS are challenging; real-world evidence in a HS population is warranted for greater disease understanding. The objective of this analysis was to describe real-world treatment patterns and treatment satisfaction in patients with HS. Methods This was a cross-sectional market research survey with retrospective data collection in patients with HS from the United States and five European countries (France, Germany, Italy, Spain, United Kingdom) between November 2020 and April 2021, using physician- and patient-reported surveys. Eligible physicians were general dermatologists actively managing patients with HS; dermatologists were required to have consulted with ≥2 patients with HS in the previous 12 months. Adult (≥18 years) and adolescent (10‒17 years) HS patients visiting a participating dermatologist were included. Outcomes included treatment patterns, flare status, treatments prescribed in response to flares, previous surgeries, barriers to biologics, and patient- and physician-reported satisfaction with the disease control provided by treatment. Results Survey data from 1787 patients were collected from 312 dermatologists. The most frequently prescribed treatments were topicals, oral antibiotics, and antiseptic washes/creams at diagnosis and sampling. At sampling, biologics were more frequently prescribed in patients with more severe disease (prescribed in 26.6%, 31.0% and 52.4% of patients with mild, moderate, and severe disease, respectively); oral antibiotics (48.8%), topicals (37.4%), and biologics (34.3%) were the most frequently prescribed treatment classes in response to a flare. Of patients currently not receiving a biologic, dermatologists reported that 18.9% of patients' condition warranted their use. Approximately one quarter of dermatologists (24.5%) and patients (27.4%) were not satisfied with current treatment; of patients who were dissatisfied, 12.8% reported they would never raise their dissatisfaction with their doctor. Conclusion These real-world data suggest a high disease burden and potential undertreatment in patients with HS. Patients received multiple treatments, and a notable proportion underwent surgery. Robustly integrating the patient voice in HS treatment decisions may lead to better outcomes and improved treatment satisfaction.

Equity and Outcome Events in Hidradenitis Suppurativa: Exploring Effect Modifiers Associated with Diagnostic Delay in the Real World.

Patients with hidradenitis suppurativa (HS) experience significantly delayed diagnoses of 7-10years from symptom onset on average, but the reasons for this remain largely unknown. This study investigated drivers of diagnostic delay from the perspective of healthcare system equity. A literature review was performed to identify published factors associated with delayed HS diagnosis to inform data analysis. Clinical and demographic data from the Adelphi HS Disease Specific Programme (DSP)™, a real-world cross-sectional survey of dermatologists and their consulting patients in France, Germany, Italy, Spain, the UK and the USA in 2020/2021, were used to model factors influencing delay to diagnosis from onset of symptoms and first consultation. Factors influencing delay to HS diagnosis in the literature with the most available evidence were misdiagnosis, delay in specialist referral and patient embarrassment. Data analysis revealed that increasing age was associated with reduced diagnostic delay after symptom onset. Patients with HS who were White or in Germany were also more likely to receive a faster diagnosis. Smokers, patients with concomitant conditions, or a family history of HS were slower to be diagnosed. When time to diagnosis following first consultation was assessed, increasing age was associated with quicker diagnosis. Moreover, patients with a family history of HS were diagnosed quicker, whereas those with high body mass index, more concomitant conditions, in employment, managed by multiple physicians or European were more delayed. On the basis of a thorough analysis of real-world data, multiple factors that potentially influenced the timely diagnosis of HS have been identified. For the first time, this study quantifies the relative impact of these modifiers, providing valuable insights into areas that require attention for faster diagnoses and improved disease outcomes.

Clinical characteristics and burden of non-obstructive hypertrophic cardiomyopathy: a real-world survey in Italy and Spain

Abstract Background Research describing non-obstructive hypertrophic cardiomyopathy (nHCM) and the associated burden of illness is sparse. Purpose This research aimed to describe the clinical characteristics of patients with nHCM and the associated clinical and societal burden of illness in Italy (IT) and Spain (ES). Methods Data were from the Adelphi HCM Disease Specific Programme (DSP), a cross-sectional survey with retrospective data collection in IT and ES (July 2022–January 2023). Ethics approval was obtained from the Pearl Institutional Review Board. Cardiologists provided data on patient demographics, employment, clinical characteristics, symptoms, support needs and treatment for up to ten consecutively consulting adult HCM patients. Patients voluntarily completed a survey containing the Kansas City Cardiomyopathy Questionnaire-23 (KCCQ). Analyses were descriptive and the mean [SD] was summarized for continuous variables. Results Overall, 112 cardiologists provided data for 483 patients with nHCM from IT (243) and ES (240). The mean age [SD] was 54.3 [14.1] and 58.0 [16.0], with 66.3% and 61.7% of patients being male, in IT and ES respectively. Eighty-four percent and 92.1% of patients were classified as New York Heart Association (NYHA) II, 14.8% and 7.1% were NYHA III, and 1.2% and 0.8% were NYHA IV, in IT and ES respectively. Among patients who completed the KCCQ, the mean [SD] KCCQ-clinical summary score was 84.9 [12.9] in IT and 81.8 [20.7] in ES. Regarding work-related impact, 30.8% (IT) and 16.7% (ES) of patients had taken time off work due to nHCM in the last three months, and 41.6% (IT) and 48.4% (ES) were not working full-time, of which 5.6% (IT) and 11.0% (ES) were not working full time due to nHCM. Additionally, 17.6% and 18.2% of patients experienced a delayed diagnosis in IT and ES respectively, with 24.0% (IT) and 25.0% (ES) having multiple delays to diagnosis. The most common symptoms reported by physicians were dyspnoea when active (83.7%), palpitations (29.3%) and fatigue (25.7%). The most prevalent concomitant conditions were hypertension (20.5%), anxiety (18.6%), and atrial fibrillation (18.4%). In IT and ES, respectively, 77.8% and 74.2% of patients were currently prescribed treatment for nHCM. The most frequently prescribed treatments were beta-blockers (83.3%), diuretics (32.1%) and angiotensin converting enzyme inhibitors (20.5%), alone or in combination. In IT and ES respectively, 14.4% and 18.8% of patients required caregiver support, at a mean [SD] of 46.3 [52.4] and 44.2 [47.5] hours per week. Conclusions While the majority of patients with nHCM were classified as NYHA II, a considerable clinical and societal burden is evident. Burden was demonstrated by the high prevalence of symptoms, comorbidities, disruptions to employment and the requirement for caregiver support among these patients, highlighting the need for new treatment and management approaches to enhance health outcomes and reduce societal impact.

Clinical and Humanistic Burden of IgAN in Adult Patients: A Global Real-World Survey.

Immunoglobulin A nephropathy (IgAN) is a chronic, progressive kidney disease in which proteinuria, reduced estimated glomerular filtration rate (eGFR), pain and fatigue are common. How symptoms interact and impact patient quality of life (QoL) in real-world practice is poorly studied. This study investigated how patient and physician symptom perceptions differ and how proteinuria and eGFR correlate with pain, fatigue, and QoL in adult IgAN patients. Data were drawn from the Adelphi IgAN Disease Specific Programme™, a cross-sectional survey of physicians and their biopsy confirmed IgAN patients in China, France, Germany, Italy, Spain, the United Kingdom, United States, and Japan, from June-October 2021. Physicians provided demographics and clinical characteristics, including pain and fatigue severity. The same patients completed a self-completion form containing questions on symptom severity, the EQ-5D-5L, Kidney Disease Quality of Life, and Work Productivity and Activity Impairment questionnaires. Symptom scores were grouped by severity and patients grouped by proteinuria and eGFR. Analysis of variance, chi-squared or Fisher's exact tests were performed as appropriate and Dunn's multiple comparisons with Bonferroni adjustment for pair-wise comparisons. Overall, 1515 patients were included (mean [standard deviation] age: 43 [15] years, 60% [n=903] male, 70% [n=1020/1459] diagnosed >1 year ago). Pain was reported by 46% (n=374) of physicians and 47% (n=384) of patients and fatigue by 65% (n=530) of physicians and 76% (n=620) of patients. Both pain and fatigue increased with increased proteinuria and reduced eGFR (all p<0.001). Finally, patients with increased proteinuria and reduced eGFR experienced worse (p<0.05) QoL and work productivity across all measures (except work absenteeism). Patients with higher proteinuria and lower eGFR face higher symptom burden and reduced QoL than their counterparts. Physicians underestimated fatigue levels faced by patients. In order to improve QoL, more effective treatments are needed to prevent high proteinuria and preserve eGFR.

Questionnaire-based real-world survey of diagnosing food allergy in children: Utilization of oral food challenge tests and other diagnostic methods

BackgroundOral food challenge tests are considered the gold standard for diagnosing food allergies; however, studies on their real-world implementation rates are limited. ObjectiveThe study aimed to investigate the proportion of school-aged children who underwent the oral food challenge test and to understand the motivations behind food elimination and utilization of various healthcare services. MethodsThe questionnaire-based survey for the parents of the students who submitted the "certificate for school life management (for allergic diseases)" was conducted across public elementary and junior high schools in Gifu Prefecture, Japan. ResultsThe study encompassed parents of 3457 children with food allergies who submitted the certificate. Approximately one-third of those eliminating the three major allergens—eggs (32.5%), milk (27.6%), and wheat (33.5%)—were diagnosed via oral food challenge tests, and approximately two-thirds were diagnosed using a combination of symptoms and blood tests, suggesting that majority of them were diagnosed appropriately. However, many children were diagnosed and eliminated foods based solely on blood tests without any symptoms of other allergens, such as buckwheat (55.8%), peanuts (29.2%), and tree nuts (21.2%), suggesting that there was likely unnecessary food elimination in these children. The elimination of buckwheat due to anxiety was associated with eliminating other foods for the same reason and eliminating two or more foods. ConclusionExamination of the real-world application of the proposed recommendations for the accurate diagnosis of food allergies suggests that close monitoring of the practical application should be conducted in each case to avoid unnecessary food elimination from children's diets.

Alopecia Areata Treatment Patterns and Satisfaction: Results of a Real-World Cross-Sectional Survey in Europe.

Alopecia areata (AA) is an autoimmune disease that causes scalp, face, and/or body hair loss. Recently, oral treatments with kinases inhibition became the first approved therapies for severe AA. An understanding of the use and effectiveness of traditional therapies in real-world treatment settings is needed to guide integration of novel therapies into the treatment paradigm. This study aimed to describe traditional treatment patterns, dermatologists' reasons for therapy choice, and dermatologists' satisfaction with disease control among patients with AA. Data were drawn from the 2021-2022 Adelphi Real World AA Disease Specific Programme™, a cross-sectional survey of dermatologists and adult patients with AA, conducted in France, Germany, Italy, Spain, and the UK. For each patient, using data from patient consultation and medical records, dermatologists reported % scalp hair loss (SHL), characteristics of current and prior AA therapies, and satisfaction with disease control. Overall, 239 dermatologists provided data for 1720 patients with AA. Mean (SD) patient age was 35.8 (11.6) years, and 51% were male. Based on dermatologist perception, among patients with ≤ 10% SHL, 74% were experiencing mild AA, while ≥ 95% of patients with ≥ 50% SHL were experiencing severe/very severe AA. In patients with ≥ 50% SHL, the most common therapies received included systemic immunosuppressants (31%), topical corticosteroids (24%), and oral corticosteroids (24%). Among all patients who had switched therapies, 49%, 26%, and 24% switched because of worsening AA, lack of initial efficacy with prior treatment, and loss of response over time, respectively. Among those with SHL ≥ 50%, dermatologists reported satisfaction with current therapy in < 30% of patients. Dermatologists reported low satisfaction with traditional AA therapies used in patients with extensive SHL, with some patients discontinuing treatment because of worsening disease. This suggests more effective treatments are needed for patients with severe AA.

Managing perceptions on the linguistic terms of qualitative scales

In this paper, we consider the problem of how individuals perceive the ordinal proximities between the linguistic terms of an ordered qualitative scale. We address the challenge of accurately measuring these ordinal proximities in ordered qualitative scales used in surveys. To tackle this issue, we have devised a visual procedure, managed through sliders, and an appropriate software that generates the metrizable ordinal measure which represents the ordinal arrangement of the proximities between the linguistic terms of an ordered qualitative scale. The procedure has been applied to real-world survey data to validate its effectiveness. The results indicate that the new proposal significantly outperforms traditional techniques in terms of accuracy and reliability, providing a robust tool for researchers in fields requiring precise ordinal data analysis.

A least-squares framework for developing interval type-2 fuzzy semantics

The developing of IT2 fuzzy semantics is critical for computing with words (CWW), but exiting approaches lack flexibility and fail to adapt user’s diversified demands. The study proposes a least-squares framework for designing CWW encoders that construct interval type-2 fuzzy sets (IT2 FSs) to represent the semantic meanings of linguistic words. In the least-squares framework, an CWW encoder is characterized by two elements: an intra-uncertain semantic mapping and an inter-uncertain semantic family. The intra-uncertain semantic mapping transforms data intervals into type-1 fuzzy sets (T1 FSs), then an optimal IT2 FS is derived from the inter-uncertain semantic family using the least-squares method. Furthermore, several intra-uncertain semantic mappings are introduced, and a compatibility measure is defined to facilitate model selection. The least-squares framework benefits from the flexible selection of intra-uncertain semantic mappings and least-squares optimization-based construction of IT2 FSs. In experiments, the least-squares framework is applied to handle real-world online survey data and the large-scale online review data set of a Chinese life service review site, Dianping.com. Compared to the enhanced interval approach and the Hao-Mendel approach, the least-squares framework shows its favorable efficiency in experiments and statistical tests, and adapts to user-defined intra- and inter-uncertain semantic families.

Patterns of Care for Brain Metastases in Asia: A Real-World Survey Conducted by the Federation of Asian Organizations for Radiation Oncology.

To report the patterns of care for brain metastases (BMs) in the Federation of Asian Organizations for Radiation Oncology (FARO). Overall, 37 questions were prepared. The survey was conducted online using Google Forms, and the URL was distributed to members of the FARO research committee. Radiation oncologists associated with FARO responded to the questionnaire between May 2023 and June 2023, and their answers were analyzed. Responses were received from 32 radiation oncologists in 13 countries participating in FARO. Twenty-six physicians (81.3%) were affiliated with academic centers, and 22 (68.8%) were able to perform stereotactic radiosurgery (SRS) or fractionated stereotactic radiotherapy (fSRT) for BMs at their institution. The most typically used prognostic index for BM was the recursive partitioning analysis classification (17 physicians, 53.1%). The maximum number of BMs indicated for SRT/SRS was ≤three (11 physicians, 34.4%), whereas eight (25.0%) physicians answered for 6-10 BMs. The maximum size of BMs considered for SRS/fSRT was ≤3 cm (14 physicians, 43.8%), whereas nine (28.1%) answered that SRS/fSRT was preferred if the maximum size was >4 cm. When whole-brain radiotherapy (RT) was indicated, hippocampal avoidance and memantine usage were limited to 50.0% and 25.0% of patients, respectively. The most typical RT modality after BM resection was SRS/fSRT alone, regardless of whether the margin was positive (19 physicians, 59.4%) or negative (13 physicians, 40.6%). We report the survey results of the patterns of care for BMs in the FARO. This survey was conducted only among a limited number of FARO members. Since many respondents were affiliated with relatively large-scale academic centers, large-scale surveys, including community hospitals, are warranted for future initiatives.

Cost-effectiveness of a novel AI technology to quantify coronary inflammation and cardiovascular risk in patients undergoing routine Coronary Computed Tomography Angiography.

Coronary Computed Tomography Angiography (CCTA) is a first line investigation for chest pain in patients with suspected obstructive coronary artery disease (CAD). However, many acute cardiac events occur in the absence of obstructive CAD. We assessed the lifetime cost-effectiveness of integrating a novel artificial intelligence-enhanced image analysis algorithm (AI-Risk) that stratifies the risk of cardiac events by quantifying coronary inflammation, combined with the extent of coronary artery plaque and clinical risk factors, by analysing images from routine CCTA. A hybrid decision-tree with population cohort Markov model was developed from 3,393 consecutive patients who underwent routine CCTA for suspected obstructive CAD and followed up for major adverse cardiac events over a median(IQR) of 7.7(6.4-9.1) years. In a prospective real-world evaluation survey of 744 consecutive patients undergoing CCTA for chest pain investigation, the availability of AI-Risk assessment led to treatment initiation or intensification in 45% of patients. In a further prospective study of 1,214 consecutive patients with extensive guideline recommended cardiovascular risk profiling, AI-Risk stratification led to treatment initiation or intensification in 39% of patients beyond the current clinical guideline recommendations. Treatment guided by AI-Risk modelled over a lifetime horizon could lead to fewer cardiac events (relative reductions of 4%, 4%, 11%, and 12% for myocardial infarction, ischaemic stroke, heart failure and cardiac death, respectively). Implementing AI-Risk classification in routine interpretation of CCTA is highly likely to be cost-effective (Incremental cost-effectiveness ratio £1,371-3,244), both in scenarios of current guideline compliance or when applied only to patients without obstructive CAD. Compared with standard care, the addition of AI-Risk assessment in routine CCTA interpretation is cost effective, by refining risk guided medical management.

Vaccination strategies for patients with lymphoma treated in early lines of therapies: a real-world practice survey among Fondazione Italiana Linfomi centers

Patient diagnosed with lymphoma presents a greater risk of infection, mainly if undergoing anti-CD20 therapy, splenectomized, hypogammaglobulinemic. They can therefore benefit from a vaccination program, especially in the watchful waiting phases or before starting oncologic treatment. The COVID-19 pandemic has raised awareness on vaccinations in frail patients, but a homogeneous approach has yet to be achieved across different vaccinations. In this sense, FIL researchers conducted a multicenter survey to evaluate the attitude of hematologists to anamnestically evaluate the patient’s vaccination history and to plan vaccinations before treatments. In this work we present the results of the survey which denote attention to the topic but not homogeneous behavior regarding the proposal and timing of vaccinations.

A real-world survey on expensive drugs used as first-line chemotherapy in patients with HER2-negative unresectable advanced/recurrent gastric cancer in the stomach cancer study group of the Japan clinical oncology group.

Molecular-targeted drugs and immune checkpoint inhibitors have been developed for various malignant diseases, thereby improving clinical outcomes. However, these drugs are expensive, and few studies have assessed their actual use and costs in Japan. This study aimed to survey the use and costs of first-line chemotherapy for advanced/recurrent gastric cancer (AGC) in real-world settings. The survey included patients with human epidermal growth factor receptor type2 (HER2)-negative AGC who initiated first-line chemotherapy from January 2022 to December 2022 at the participating 92 institutions in the Japan Clinical Oncology Group. Data on the regimens were collected using Google Forms. A regimen that costs >500 000 Japanese yen (JPY) per month was defined as expensive. Data on chemotherapy regimens were collected from 2173 patients at all 92 institutions between March 2023 and May 2023. We analyzed 2113 patients who underwent the chemotherapy with recommended regimens and conditionally recommended regimens according to the Japanese Gastric Cancer Treatment Guidelines sixth edition. The expensive regimens were triplet chemotherapy with fluoropyrimidine (S-1 or capecitabine or 5-fluorouracil/levofolinate), oxaliplatin, and nivolumab. Their monthly costs ranged from 767 648 to 771 046 JPY. Nivolumab-containing regimens cost more than 20 times the price of conventional chemotherapy with fluoropyrimidine and oxaliplatin. These regimens were used in 1416 (67%) of 2113 patients: in 71% of patients aged ≤74years and in 59% of patients aged ≥75years. The regimens with >20-fold cost of conventional chemotherapy were used as first-line chemotherapy in two-thirds of patients and more than half even in the elderly population with HER2-negative AGC. This finding is important for future health economic studies on drug cost-efficacy.

Diagnosis, treatment and burden in advanced ovarian cancer: a UK real-world survey of healthcare professionals and patients.

Aim: Little is known regarding uptake of epithelial ovarian cancer (EOC) treatments or patient burden in UK real-world practice.Methods: Cross-sectional surveys of patients with advanced EOC and healthcare professionals (HCPs).Results: 101 HCPs and 142 patients participated. Time from initial primary care consultation to diagnosis was ∼7weeks. 83% patients were offered hereditary genetic testing, with 89% uptake. 53% HCPs reported surgery was performed ≤1month in non-neoadjuvant setting. Surgery delay negatively impacted patient quality of life(61%), mental health (89%), and surgical outcomes (63%). 56% patients received active first-line maintenance treatment; patients on active surveillance had greater emotional/psychological distress.Conclusion: Treatment delays and low uptake of active first-line treatment should be addressed. Emotional support must be readily accessible throughout treatment.

Healthcare resource utilization and economic burden of multiple sclerosis in Chinese patients: results from a real-world survey

Multiple sclerosis (MS) is uncommon in China and the standard of care is underdeveloped, with limited utilization of disease-modifying treatment (DMT). An understanding of real-world disease burden (including direct medical, non-medical, and indirect costs, such as loss of productivity), is currently lacking in this population. To investigate the overall burden of managing patients with MS in China, a cross-sectional survey of physicians and their consulting patients with MS was conducted in 2021. Physicians provided information on healthcare resource utilization (HCRU; consultations, hospitalizations, tests, medication) and associated costs. Patients provided data on changes in their life, productivity, and impairment of daily activities due to MS. Results were stratified by disease severity using generalized linear models, with a p value < 0.05 considered statistically significant. Patients with more severe disease had greater HCRU, including hospitalizations, consultations and tests/scans, and incurred higher direct and indirect costs and productivity loss, compared with those with milder disease. However, the use of DMT was higher in patients with mild disease severity. With the low uptake and limited efficacy of non-DMT drugs, Chinese patients with MS experience a high disease burden and significant unmet needs. Therapeutic interventions could help save downstream costs and lessen societal burden.

Androgen deprivation therapy in advanced prostate cancer: insights from a real-world patient survey on health-related quality of life and information and communication sources.

Androgen deprivation therapy (ADT) is a cornerstone treatment for advanced and metastatic prostate cancer. Real-world and patient-reported insights into ADT's impact on health-related quality of life (HRQoL) and communication experiences in healthcare settings remain underexplored. This patient organisation-initiated online survey aimed to assess these aspects. Between December 2022 and August 2023, the patient organisation Think Blue Vlaanderen and the AZ Sint-Jan Hospital (Bruges, Belgium) invited ADT-treated patients to participate in a prospective, online, cross-sectional, patient-reported outcome survey. Demographic, clinical, HRQoL (FACT and EPIC-26), communication sources and information modality data were collected. Descriptive statistics and comparative analyses were applied. A total of 276/312 (88.5%) participating patients were on ADT at time of survey administration and completion, with the majority receiving a 3-monthly regimen. Sexual HRQoL was low and narrowly distributed (median (IQR): 16.7 (16.7-16.7)), with 84% of patients having erectile dysfunction (ED). Patients finding their ED problematic were more likely to seek pharmaceutical treatment. Hormonal HRQoL was widely distributed (median (IQR): 65 (45-85)), which improved with prolonged ADT duration. Physically active patients reported less lack of energy, but increased hot flashes. Within consistent FACT-G summary scores (median (IQR): 64.50 (54.75-77.00)), improved emotional wellbeing with prolonged ADT was noted. Multidisciplinary communication and multimodal information provision improved patient satisfaction. Patient organisation-initiated surveys offer real-world and patient-reported insights. Patient-tailored HRQoL assessments and longitudinal follow-up, physical activity, and multidisciplinary and multimodal communication approaches are warranted to improve patient-centred care in patients receiving ADT.
