Impression life with pulmonary hypertension: clinically relevant characteristics and quality of life among patients in Gansu, China.

BACKGROUND: The adverse effects of pulmonary arterial hypertension (PAH) on physical, emotional, and health-related quality of life (HRQoL) remain primarily unrecognized, especially in resource-limited settings. OBJECTIVES: This study aims to characterize the HRQoL of patients with PAH in this area and also identify the potential role of clinically relevant characteristics, including the 6-min walk distance test (6MWD), WHO-Functional Classification (WHO-FC), and mental health in the occurrence of lowering quality of life. DESIGN: This was a cross-sectional observational study. METHODS: Inpatients with PAH were chosen from a tertiary hospital located in Gansu province, China. All participants were interviewed face-by-face by using questionnaires, including items from the 36-Item Short Form Health Survey (SF-36), the self-rating anxiety scale, and the self-rating depression scale. Data on demographic and clinically relevant characteristics, including WHO-FC and 6MWD, were also collected by tracing medical recorders. Multiple linear regression analysis was used to determine the association between demographic, clinically relevant characteristics data, and physical component summary (PCS) or mental component summary (MCS) in SF-36. RESULTS: Of the 152 participants, SF-36 differed significantly from Chinese norms in all eight domains, with role-physical (21.55 ± 9.87) less than one-third of the norm (88.79 ± 28.49). Multiple linear regression results showed that the factors with the greatest impact on PCS were anxiety scores (ß = -0.22, p = 0.001), followed by WHO-FC (ß = -0.16, p = 0.014) and 6MWD (ß = 0.15, p = 0.036). The factors with the greatest impact on MCS were WHO-FC (ß = -0.30, p < 0.001), followed by anxiety (ß = -0.23, p = 0.001) and depression scores (ß = -0.16, p = 0.013). CONCLUSION: HRQoL was substantially reduced among PAH patients in the resource-limited area, mainly the physiological functions. WHO-FC and anxiety scores were independently associated with both PCS and MCS in SF-36. Clinicians should make reasonable rehabilitation programs and plans for patients according to their cardiac function grade and the severity of clinical symptoms. In addition, psychological interventions should also be taken, especially for those with anxiety symptoms, so as to improve their HRQoL.

Quality of life of patients with pulmonary arterial hypertension: a meta-analysis.

OBJECTIVE: Pulmonary arterial hypertension (PAH) is a rare condition, with an incidence of 15-50 cases per million annually. Available studies demonstrate that despite the longer survival of PAH patients, their quality of life (QoL) deteriorates as the condition progresses. Consequently, the goals of PAH therapy have expanded from increasing survival to improving health-related quality of life. The objective of this systematic review and meta-analysis was to summarize the available evidence about the level of QoL in patients with PAH. MATERIALS AND METHODS: A systematic search was performed using the Cochrane guidelines for conducting meta-analysis following the PRISMA statement. The meta-analysis includes findings from 11 studies evaluating the QoL of PAH patients at baseline and at follow-up (12 weeks) using the Short Form (36) Health Survey (SF-36), the Minnesota Living with Heart Failure Questionnaire (MLHFQ) and the Cambridge Pulmonary Hypertension Outcome Review (CAMPHOR). RESULTS: The mean physical component score (SF-36) for the group was 37.2 points (95% CI: 33.24-41.16) and the heterogeneity coefficient was I²=97.71% (p < 0.001). The mean mental component score (SF-36) was 46.38 (95% CI: 44.21-48.56) and the heterogeneity coefficient was I²=87.92% (p < 0.001). The result indicates improved QoL 12 weeks after the intervention, though three papers did not fully confirm this. The greatest improvement in QoL was found in patients treated with bosentan and iloprost and the smallest improvement in QoL was found in patients treated with epoprostenol sodium. The heterogeneity coefficient was I²=91.36%, p < 0.001 for CAMPHOR and I²=97.65%, p < 0.001 for MLHFQ. CONCLUSIONS: PAH patients tend to have a poor QoL, mainly in the physical functioning domain, less so in the psychological functioning domain. QoL may be improved by therapeutic interventions, mainly pharmaceutical ones. Patients with PAH also tend to suffer from depression, anxiety, stress, or sleep disorders. All these factors are significantly correlated with poorer QoL.

A Mobile Health Intervention to Increase Physical Activity in Pulmonary Arterial Hypertension.

BACKGROUND: Supervised exercise training improves outcomes in patients with pulmonary arterial hypertension (PAH). The effect of an unsupervised activity intervention has not been tested. RESEARCH QUESTION: Can a text-based mobile health intervention increase step counts in patients with PAH? STUDY DESIGN AND METHODS: We performed a randomized, parallel arm, single-blind clinical trial. We randomized patients to usual care or a text message-based intervention for 12 weeks. The intervention arm received three automated text messages per day with real-time step count updates and encouraging messages rooted in behavioral change theory. Individual step targets increased by 20% every 4 weeks. The primary end point was mean week 12 step counts. Secondary end points included the 6-min walk test, quality of life, right ventricular function, and body composition. RESULTS: Among 42 randomized participants, the change in raw steps between baseline and week 12 was higher in the intervention group (1,409 steps [interquartile range, -32 to 2,220] vs -149 steps [interquartile range, -1,010 to 735]; P = .02), which persisted after adjustment for age, sex, baseline step counts, and functional class (model estimated difference, 1,250 steps; P = .03). The intervention arm took a higher average number of steps on all days between days 9 and 84 (P < .05, all days). There was no difference in week 12 six-minute walk distance. Analysis of secondary end points suggested improvements in the emPHasis-10 score (adjusted change, -4.2; P = .046), a reduction in visceral fat volume (adjusted change, -170 mL; P = .023), and nearly significant improvement in tricuspid annular plane systolic excursion (model estimated difference, 1.2 mm; P = .051). INTERPRETATION: This study demonstrated the feasibility of an automated text message-based intervention to increase physical activity in patients with PAH. Additional studies are warranted to examine the effect of the intervention on clinical outcomes. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov; No. NCT03069716; URL: www.clinicaltrials.gov.

The effect of oral sildenafil therapy on health-related quality of life in adults with pulmonary arterial hypertension related to uncorrected secundum atrial septal defect: a quasi experimental study.

BACKGROUND: Assessment of health-related quality of life (HRQoL) are often measured as an important patient-reported outcome (PRO) in clinical studies. Pulmonary arterial hypertension (PAH) is a common complication of atrial septal defect (ASD). This study aimed to compare the HRQoL of PAH related uncorrected secundum ASD at pre and post therapy with oral sildenafil therapy. METHODS: We conducted quasi experimental study at Sardjito General Hospital Yogyakarta since April 2016 to August 2017. Adults with PAH related uncorrected secundum ASD, listed on Congenital Heart Disease and Pulmonary Hypertension (COHARD-PH) registry, and met the inclusion and exclusion criteria were recruited as subject. Interview was done at pre and 12 weeks post oral sildenafil therapy 3 × 20 mg using the EQ-5D-3L questionnaire. Statistical analysis was done using Wilcoxon test and paired T-test to determine the differences of EQ-5D utility and EQ-VAS score at pre and post therapy. RESULTS: A total of 18 adult patients with PAH related to uncorrected secundum ASD were enrolled in this study (83.33% female; mean age 38.72 ± 10.81 years old). The most frequent reported problems pre therapy were pain/discomfort (83%) and anxiety/depression (78%). Wilcoxon test showed the median of EQ-5D utility score were increased after sildenafil therapy (before = 0.604, after = 0.664; Z = - 2703; p:0.007), respectively. Meanwhile, the paired T-test results showed an increase of EQ-VAS mean difference 6.67 ± 8.75 (p:0.005; 95% CI 2.32-11.02) after sildenafil therapy. CONCLUSION: The administration of oral sildenafil therapy 3 × 20 mg during 12 weeks in adult patients with PAH related uncorrected secundum ASD gives better HRQoL.

Inpatient Palliative Care Use in Patients With Pulmonary Arterial Hypertension: Temporal Trends, Predictors, and Outcomes.

BACKGROUND: Pulmonary arterial hypertension (PAH) is a progressive disease associated with significant morbidity and mortality. Despite the negative impact of PAH on quality of life and survival, data on use of specialty palliative care services (PCS) is scarce. RESEARCH QUESTION: We sought to evaluate the inpatient use of PCS in patients with PAH. STUDY DESIGN AND METHODS: Using the National (Nationwide) Inpatient Sample, 30,495 admissions with a primary diagnosis of PAH were identified from 2001 through 2017. The primary outcome of interest was temporal trends and predictors of inpatient PCS use in patients with PAH. RESULTS: The inpatient use of PCS was low (2.2%), but increased during the study period from 0.5% in 2001 to 7.6% in 2017, with a significant increase starting in 2009. White race, private insurance, higher socioeconomic status, hospital-specific factors, higher comorbidity burden (Charlson Comorbidity Index), cardiac and noncardiac organ failure, and use of extracorporeal membrane oxygenation and noninvasive mechanical ventilation were independent predictors of increased PCS use. PCS use was associated with a higher prevalence of do-not-resuscitate status, a longer length of stay, higher hospitalization costs, and increased in-hospital mortality with less frequent discharges to home, likely because these patients were also sicker (higher comorbidity index and illness acuity). INTERPRETATION: The inpatient use of PCS in patients with PAH is low, but has been increasing over recent years. Despite increased PCS use over time, patient- and hospital-specific disparities in PCS use continue. Further studies evaluating these disparities and the role of PCS in the comprehensive care of PAH patients are warranted.

Conversational avoidance during existential interviews with patients with progressive illness.

We examined patterns of avoidance when existential emotional topics were raised during conversations with patients with pulmonary arterial hypertension (PAH), an incurable life-limiting disease. 30 adult outpatients with PAH were recruited for a 20 to 60-minute interview about their illness experience. Qualitative content analysis was used to identify avoidance strategies that patients employed. Participants averaged 58 years in age (SD = 18), 77% were female, and mean length of illness was 6.3 years (SD = 5.3). We found four avoidance strategies: (1) Reversal, when individuals would begin discussing a negative concern and then backtrack to more positive sentiments; (2) Diversion for when patients would sidetrack the conversation to a different and less uncomfortable topic; (3) Diminishment for when a concern is raised and then made to seem unimportant; and (4) Obstruction, when patients refuse to discuss a concern further. Exploration of existential concerns can elicit distress but may be necessary to promote adaptation to progressive illness and to the foreseeable challenges that may affect the sense of life meaning and value. By recognizing when existential concerns may be present but not adequately discussed, clinicians may be better able to assist patients to cope and prepare for the future.

Health-related quality of life, treatment adherence and psychosocial support in patients with pulmonary arterial hypertension or chronic thromboembolic pulmonary hypertension.

Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) share similar quality of life impairment. The aim of the present study was to investigate health-related quality of life (HRQoL) and its relation to the perception of treatment and psychosocial support among PAH and CTEPH patients. All adult PAH or CTEPH patients in the Swedish Pulmonary Arterial Hypertension Register were invited to participate in a national cohort survey. The survey included the EuroQol 5-dimensions (EQ-5D) instrument that measures an individual's HRQoL; the Beliefs about Medicines Questionnaire-Specific Scale that assesses the perception of PAH-specific treatment; the Mastery scale that evaluates the feeling of control and ability to cope with the disease; and the Social Network and Support Scale that maps the social support network. Of the 440 invited patients, 74% responded. Mean age was 66 ± 14 years, 58% were female and 69% diagnosed with PAH. Patients with PAH were younger, more often female and had a lower EQ-5D index (0.67 ± 0.29 vs. 0.73 ± 0.25, p = 0.050) than patients with CTEPH. Patients with a low EQ-5D index had more concerns about treatment ( p = 0.004), lower coping ability ( p < 0.001), less emotional support ( p = 0.003) and less accessible social network ( p = 0.002). In conclusion, patients with an impaired HRQoL also reported negative effects on their social support network, ability to handle stressors and concerns about treatment.

Perceived burden in dealing with different rare diseases: a qualitative focus group study.

OBJECTIVES: There are more than 6000 heterogeneous rare diseases and little is known about shared experiences of affected individuals in everyday life and healthcare. Objective of this study was to explore perceived burden of patients with rare chronic diseases and identify commonalities and differences in the experiences of patients with four heterogeneous conditions. DESIGN: A qualitative focus group study. SETTING: In four separate and diagnostically homogeneous focus groups, we asked patients about the perceived burden of living with their rare disease. The focus groups took place at a university medical centre in Germany. PARTICIPANTS: Individuals with neurofibromatosis type 1 (n=4), primary sclerosing cholangitis (n=5), pulmonary arterial hypertension (n=4) and Marfan syndrome (n=5). RESULTS: We identified five main themes: medical problems, psychological burden, problems with the healthcare system, constraints and interpersonal problems. While medical problems differed widely between the diagnostic groups, patients with different conditions independently reported many common problems including psychological burden, constraints in professional, personal and daily life, stigmatisation and others lacking understanding. Shared problems pertaining to the healthcare system seem related to the rarity of the conditions (eg, limited access to adequate care, lack of knowledge). CONCLUSIONS: Despite clinical heterogeneity of rare diseases, affected individuals have many common experiences. Some of these experiences may resemble the burden of living with a chronic disease. However, patients reported aspects, which seem to be specific for rare chronic diseases. Generic interventions targeting shared burdens among patients with different diseases could provide adequate treatment in light of finite healthcare resources.
