Patient perception of disease burden in diffuse cutaneous systemic sclerosis.

Purpose: Systemic sclerosis is a rare multi-organ autoimmune rheumatic disease, resulting in progressive fibrosis of the skin/internal organs. This study aimed to understand the impact of diffuse cutaneous systemic sclerosis symptoms and disease burden from the patient's perspective. Methods: This was a mixed methodology, market research study involving ethnography, structured interviews, video diaries, and patient tasks. Patients had been diagnosed with diffuse cutaneous systemic sclerosis for ⩾ 6 months and were recruited via healthcare professionals or patient associations (France, Italy, the United Kingdom, and the United States). Patients filmed short (~15 min) daily video diaries about their lives over 7 days and participated in ethnographic sessions, patient tasks, and structured video interviews. In Germany and Spain, patients participated in 60-min telephone interviews. Results: Twenty-three patients (mean age: 54 years; 83% women; minimum disease duration: 6 months) participated in the study. Time to diagnosis was prolonged, as patients overlooked their symptoms and some healthcare professionals attributed symptoms to other causes. Patients rarely received additional information or support services at diagnosis. Importantly, although patients were aware of the seriousness of organ involvement, they reported that skin changes, pain, and fatigue impaired their ability to perform routine tasks. Patients had a high prescription treatment burden (mean: 10 tablets/day; up to >25 tablets/day) with additional non-prescription medication taken for other comorbidities. Treatment discontinuation was common due to side effects. Patients experienced diffuse cutaneous systemic sclerosis as a loss of independence and self-esteem. Moreover, patients tended to have small support networks, and emotional support services were not offered as standard care. Conclusion: Patients with diffuse cutaneous systemic sclerosis had high treatment and disease burdens, with skin changes, pain, and fatigue profoundly affecting their lives. There is an unmet need for patient information at the time of diagnosis and emotional support services throughout the patient's journey with diffuse cutaneous systemic sclerosis. Based on the results of this study, we provide recommendations for improving diffuse cutaneous systemic sclerosis care.

Factors influencing early referral, early diagnosis and management in patients with diffuse cutaneous systemic sclerosis.

Objective: To gain insight into clinical practice regarding referral, early diagnosis and other aspects of the management of patients with dcSSc in Europe and the USA. Methods: Semi-structured interviews were conducted with 84 rheumatologists (or internal medicine physicians) and 40 dermatologists in different countries (the UK, France, Germany, Italy, Spain and the USA). Physicians were asked to identify key steps in the patient pathway relating to patient presentation, diagnosis and referral, in addition to other treatment and follow-up processes. Results: The interviewed physicians reported that late presentation with dcSSc was common, with some patients presenting to primary care physicians after symptoms had persisted for up to 1 year. Awareness of dcSSc is reported to vary widely among primary care physicians. Final diagnosis, generally following guideline-based recommendations, was by rheumatologists in most cases (or internal medicine physicians in France) and they remained responsible for global patient management, with lesser involvement in diagnosis and management by dermatologists. Specialist centres were not well defined and did not exist in all countries. Conclusion: Patients and primary healthcare providers can be unaware of the symptoms of dcSSc, therefore presentation and referral to specialist care are often late. Thus, improved awareness among patients and primary care physicians is necessary to facilitate earlier referral and diagnosis. Once referred, more consistent use of the modified Rodnan skin score at diagnosis and follow-up may help to monitor disease progression. Furthermore, establishing specialist centres may help to promote such changes and improve patient care.

An epidemiological analysis of the burden of chronic thromboembolic pulmonary hypertension in the USA, Europe and Japan.

Epidemiological data for chronic thromboembolic pulmonary hypertension (CTEPH) are limited and there are conflicting reports regarding its pathogenesis.A literature review was conducted to identify CTEPH epidemiological data up to June 2014. Data were analysed to provide estimates of the incidence of CTEPH in the USA, Europe and Japan. An epidemiological projection model derived country-specific estimates of future incidence and diagnosis rates of CTEPH.Overall, 25 publications and 14 databases provided quantitative epidemiological data. In the USA and Europe, the crude annual incidence of diagnosed pulmonary embolism and crude annual full (i.e. diagnosed and undiagnosed) incidence of CTEPH were 66-104 and 3-5 cases per 100 000 population, respectively, while in Japan these rates were lower at 6.7 and 1.9 per 100 000 population, respectively. In 2013, 7-29% of CTEPH cases in Europe and the USA were diagnosed, and the majority of patients were in New York Heart Association functional class III/IV at diagnosis. The projection model indicated that incidence of CTEPH will continue to increase over the next decade.These data suggest that CTEPH is underdiagnosed and undertreated, and there is an urgent need to increase awareness of CTEPH. High-quality epidemiological studies are required to increase understanding of CTEPH.

An international physician survey of pulmonary arterial hypertension management.

We conducted an international study to evaluate practices in the diagnosis and management of pulmonary arterial hypertension (PAH) globally across different geographic regions. Between July and October 2012, PAH-treating physicians completed a 15-minute online questionnaire and provided patient record data for their 3 or 5 most recent patients with PAH. Overall, 560 physicians (Europe: 278; United States: 160; Argentina: 53; Japan: 69) completed the questionnaire and provided data for 2,618 patients. The proportion of physicians who described themselves as working in or affiliated with a specialized pulmonary hypertension center ranged from 13% in Argentina to 74% in the United States. At the time of diagnosis, patients' New York Heart Association functional class differed significantly between regions. At the time of last assessment, functional class had improved overall, and differences between regions had largely disappeared. A large proportion of patients did not undergo right heart catheterization for the diagnosis of PAH (Europe: 7%-21%; United States: 21%; Japan: 19%; Argentina: 51%). Variations in management included greater use of phosphodiesterase 5 inhibitors in the United States than in Europe and Japan and greater use of triple or greater combination therapy in Japan than in other regions. Results from this study, which includes a global aspect of PAH care, demonstrate that there are significant differences in PAH management between regions and low adherence to guidelines recommending right heart catheterization for the diagnosis of PAH.

An international physician survey of chronic thromboembolic pulmonary hypertension management.

We conducted an international study to evaluate practices in the diagnosis and management of patients with chronic thromboembolic pulmonary hypertension (CTEPH) globally across different regions. Between August and October 2012, CTEPH-treating physicians completed a 15-minute online questionnaire and provided patient record data for their 2-5 most recent patients with CTEPH. Overall, 496 physicians (Europe: 260; United States: 152; Argentina: 52; Japan: 32) completed the questionnaire and provided patient record data for 1,748 patients. The proportion of physicians who described themselves as working in or affiliated with a specialized pulmonary hypertension (PH) center ranged from 38% in France and Italy to 83% in the United States. A large proportion of patients did not undergo ventilation/perfusion scanning (46%-67%) or right heart catheterization (24%-57%) for the diagnosis of CTEPH. Referral rates for pulmonary endarterectomy evaluation ranged from 25% in Japan to 44% in Europe, with higher referral rates in PH centers; the main reasons for lack of referral were that surgery was not considered unless medical treatment was failing and patient refusal. Other variations in management included greater use of phosphodiesterase 5 inhibitors in the United States than in Europe and Japan and greater use of combination treatment in the United States than in Europe. Physicians' perceptions of their treatment strategy were generally consistent with patient record data. Results from this study, which includes a global aspect of CTEPH care, demonstrate not only regional differences in CTEPH management but, more importantly, considerable nonadherence to the diagnosis and treatment guidelines for CTEPH, even in PH centers.

Living with pulmonary hypertension: unique insights from an international ethnographic study.

OBJECTIVES: To better understand the patient's perspective of pulmonary hypertension (PH), including the impact of living with PH, disease management and treatment. DESIGN: This qualitative ethnographic study collected observational video footage, supplemented by field notes and patient diaries to assess the impact of PH on the patient's life. SETTING: Patients were observed and filmed in their home for up to 6 h, capturing the environment, interactions and activities of everyday life. PARTICIPANTS: Patients with pulmonary arterial hypertension (PAH) or chronic thromboembolic PH who were receiving PAH-specific medication were recruited through healthcare professionals (HCPs) and patient associations in seven countries across four continents. Sampling was purposive and subgroup analysis was not intended. RESULTS: Overall, 39 patients with PH were enrolled. Many patients had a poor understanding of PH and found their 'invisible' disease difficult to explain to others. An important finding was the secrecy surrounding PH. Feelings of insecurity and isolation were regularly reported, and many patients admitted to hiding their symptoms. The marked improvement in symptoms after therapy initiation made assessment of disease progression more difficult as patients compared their quality of life (QoL) against pretreatment levels. Extensive planning and adherence to daily routines were required in patients' everyday life. CONCLUSIONS: Ethnography was used for the first time, in several countries, to evaluate the patient's perception of living with PH. This approach revealed key findings that would not typically be uncovered using other qualitative techniques, including the secrecy surrounding PH, the difficulties in describing the disease and the challenges in assessing disease progression. A more tailored dissemination of information from HCPs and development of a simple and understandable PH definition may be beneficial in alleviating the secrecy reported by patients. A greater appreciation of how patients perceive their disease and QoL has the potential to improve PH management.
