Symptom Interference Severity and Health-Related Quality of Life in Pulmonary Arterial Hypertension

Evaluating Clinical and Sociodemographic Risk for Symptom Burden Associated Interference With Daily Functioning in the Primary Brain Tumor Patient Population

INTRODUCTION

Symptom burden associated with interference in daily functioning is worse in those with progression or higher-grade glial tumors. This exploratory study aims to identify factors associated with its severity in a diverse cross-sectional cohort of 566 brain tumor patients enrolled in a natural history study (NCT03251989, PI: T.S. Armstrong).

METHODS

Sociodemographic and clinical data and self-reported activity-related interference (work, general activity, walking), mood-related interference (relations with others, enjoyment of life, mood) were reported via the MD Anderson Symptom Inventory-Brain Tumor. Activity and mood-related interference mean scores ≥ 2 were categorized as moderate-severe. Logistic regression assessed univariate associations with moderate-severe interference. Characteristics significant in the univariate analysis were included in a multivariable analysis.

RESULTS

This patient sample had a median age of 48 years (18-85), was mostly male (57%), with a high-grade tumor (73%), glioblastoma (39%), and tumor recurrence (49%). Risk factors for moderate-severe activity-related interference included: ≥ 2 surgeries (OR = 1.64, 95% CI [1.10, 2.44], p = 0.015), ependymoma (OR = 2.59, 95% CI [1.21-5.53], p = 0.014), and childhood in a rural area (OR = 1.74, 95% CI [1.15-2.63] p = 0.009). Risk factors for moderate-severe mood-related interference included tumor progression (OR = 2.02, 95% CI [1.21-3.36], p = 0.009).

CONCLUSION

Patient reported interference with daily physical functioning is associated with sociodemographic and disease-related characteristics and notably worse mood-related interference in those with progression. Future studies should include social determinants of health and change over time to identify and plan interventions for those at risk.

Sleep Quality and Its Predictors among Dyspnea, Fatigue and Exercise Capacity in Pulmonary Arterial Hypertension

Background

Poor sleep quality is an overlooked symptom in patients with pulmonary arterial hypertension (PAH), however it may significantly contribute to disease burden.

Objectives

The aim of this study was to assess the sleep quality of patients with PAH and investigate its association with dyspnea, fatigue, and exercise capacity.

Methods

Forty-five patients were included. Sleep quality of the patients was assessed by the Pittsburgh Sleep Quality Index (PSQI), dyspnea levels were assessed by the UCSD-Shortness of Breath Questionnaire (UCSD-SOBQ), Baseline Dyspnea Index (BDI), Modified Medical Research Council (MMRC) dyspnea scale and Modified Borg Dyspnea scale, fatigue levels were evaluated with the Fatigue Severity Scale and Borg Rating of Perceived Exertion, and functional exercise capacity was evaluated with the 6-minute walk test (6MWT).

Results

Among the patients with PAH, 64% had poor sleep quality (PSQI > 5). PSQI score was significantly correlated with MMRC scale (r = -0.561), UCSD-SOBQ (r = 0.497), BDI (r = -0.468), and 6MWT (r = -0.412) (p < 0.05). There was no significant relationship between sleep quality and fatigue. A regression model including MMRC and 6MWT could explain 32% of variance in PSQI (p < 0.05), and MMRC score was an independent predictor for PSQI (p < 0.05). In addition, MMRC score had a greater influence on PSQI than 6MWT (β = 0.548 vs. 0.019).

Conclusions

Poor sleep quality is common in patients with PAH and is associated with poor exercise capacity and dyspnea. Patients with severe dyspnea are particularly at higher risk of poor sleep quality. Consideration of sleep-related complaints and underlying mechanisms when planning symptomatic treatments for these patients may help provide better management for PAH.

Does All Social Support Work? Examining the Mechanisms of Patient-Reported Symptom Interference after Esophagectomy Affecting Life Satisfaction

Purpose

We intended to explore the chain mediation role of resilience and different sources of social support on the relationship between symptom interference and life satisfaction from the patient-reported perspective.

Patients and Methods

Two hundred and twenty-six patients after esophagectomy were investigated using four validated scales to estimate the symptom interference, resilience, different sources of social support, and life satisfaction. The chain mediation analysis was conducted using SPSS PROCESS Macro Model 6.

Results

Mediation analysis showed that symptom interference indirectly influenced life satisfaction through two significant mediating pathways: (i) resilience (B = -0.138, 95% CI: -0.194 to -0.091); (ii) the chain mediators involving in resilience and family support (B = -0.049, 95% CI: -0.073 to -0.026). Surprisingly, the mediating pathway of family support was not significant.

Conclusion

Interventions for resilience and family support could mitigate the adverse effects of symptom interference in patients after esophagectomy, improving life satisfaction. Of these, resilience may be more critical in terms of the utilization of social resources than family support.

Use of the National Cancer Institute Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events to assess treatment tolerability in pulmonary arterial hypertension: qualitative patient research findings in current and former users of oral selexipag

BACKGROUND

Understanding patients' perspectives regarding drug tolerability, in addition to effectiveness, provides a complete picture of the patient experience and supports more informed therapeutic decision-making. The item library of the National Cancer Institute's Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) was developed to measure patient-reported frequency, severity, and interference of adverse events (AEs) associated with cancer therapies. This qualitative interview study assessed the suitability of items selected from the PRO-CTCAE library for assessing tolerability of selexipag, a medication targeting the prostacyclin pathway for patients with pulmonary arterial hypertension (PAH).

METHODS

Two rounds of 10 qualitative, web-assisted telephone interviews following a semi-structured guide were conducted in individuals with recent experience taking oral selexipag for PAH. Each interview included concept elicitation to gather participants' perspectives on symptomatic AEs (type, frequency, severity, and interference) and cognitive debriefing of PRO-CTCAE items addressing the most frequently reported AEs of oral selexipag.

RESULTS

Interviews were conducted with 20 participants with PAH (mean [range] age 50 [24-68] years; 75% female; 85% in World Health Organization Functional Class II-III), comprising different races/ethnicities, levels of education, and employment status. Fifteen participants were currently treated with selexipag; five had taken selexipag for ≥ 6 months before discontinuing. The most frequently reported AEs included headache, jaw pain, and nausea (n = 15, 12, and 10 participants, respectively). Diarrhea and headache were identified as the most bothersome AEs by 5 and 4 participants, respectively. Some AEs were transitory (e.g., jaw pain); others were long-lasting (e.g., muscle pain). Based on findings from Round 1 interviews, a flushing item was added and the PRO-CTCAE general pain item was modified to be specific to jaw pain for testing in Round 2. Interview findings identified the following AEs as relevant to assess in a PAH clinical trial: nausea, vomiting, diarrhea, flushing, jaw pain, headache, aching muscles, and aching joints.

CONCLUSIONS

The PRO-CTCAE items selected in this study and the additional symptomatic AEs identified as patient-relevant have the potential to be included in assessments capturing the patient perspective on tolerability in future studies of selexipag and possibly other PAH therapies.

Symptom phenotypes in pulmonary arterial hypertension: The PAH "symptome"

Women with pulmonary arterial hypertension (PAH) experience multiple symptoms, including dyspnea, fatigue, and sleep disturbance, that impair their health-related quality of life (HRQOL). However, we know little about phenotypic subgroups of patients with PAH with similar, concurrent, multiple symptoms. The objectives of this study were to define the "symptome" by symptom cluster phenotypes and compare characteristics such as biomarkers, cardiac structure and function (echocardiography), functional capacity (6-min walk distance), and HRQOL between the groups. This cross-sectional study included 60 women with PAH. Subjects completed an assessment battery: Pulmonary Arterial Hypertension Symptom Scale, Pittsburgh Sleep Quality Index, Multidimensional Dyspnea Profile, Patient-Reported Outcomes Measurement Information System (PROMIS®) Physical Function, PROMIS® Sleep-Related Impairment, and the emPHasis-10. Subjects also underwent transthoracic echocardiography, phlebotomy, 6-min walk distance, and actigraphy. The three symptoms of dyspnea, fatigue, and sleep disturbance were used to define the symptom clusters. Other PAH symptoms, plasma and serum biomarkers, cardiac structure and function (echocardiography), exercise capacity (6-min walk distance), sleep (actigraphy), and HRQOL were compared across phenotypes. The mean age was 50 ± 18 years, 51% were non-Hispanic white, 32% were non-Hispanic Black and 40% had idiopathic PAH. Cluster analysis identified Mild (n = 28, 47%), Moderate (n = 20, 33%), and Severe Symptom Cluster Phenotypes (n = 12, 20%). There were no differences for age, race, or PAH etiology between the phenotypes. WHO functional class (p < 0.001), norepinephrine levels (p = 0.029), right atrial pressure (p = 0.001), physical function (p < 0.001), sleep onset latency (p = 0.040), and HRQOL (p < 0.001) all differed significantly across phenotypes. We identified three distinctive symptom cluster phenotypes (Mild, Moderate, and Severe) for women with PAH that also differed by PAH-related symptoms, physical function, right atrial pressure, norepinephrine levels, and HRQOL. These phenotypes could suggest targeted interventions to improve symptoms and HRQOL in those most severely affected.

A wrinkle in time: circadian biology in pulmonary vascular health and disease

An often overlooked element of pulmonary vascular disease is time. Cellular responses to time, which are regulated directly by the core circadian clock, have only recently been elucidated. Despite an extensive collection of data regarding the role of rhythmic contribution to disease pathogenesis (such as systemic hypertension, coronary artery, and renal disease), the roles of key circadian transcription factors in pulmonary hypertension remain understudied. This is despite a large degree of overlap in the pulmonary hypertension and circadian rhythm fields, not only including shared signaling pathways, but also cell-specific effects of the core clock that are known to result in both protective and adverse lung vessel changes. Therefore, the goal of this review is to summarize the current dialogue regarding common pathways in circadian biology, with a specific emphasis on its implications in the progression of pulmonary hypertension. In this work, we emphasize specific proteins involved in the regulation of the core molecular clock while noting the circadian cell-specific changes relevant to vascular remodeling. Finally, we apply this knowledge to the optimization of medical therapy, with a focus on sleep hygiene and the role of chronopharmacology in patients with this disease. In dissecting the unique relationship between time and cellular biology, we aim to provide valuable insight into the practical implications of considering time as a therapeutic variable. Armed with this information, physicians will be positioned to more efficiently use the full four dimensions of patient care, resulting in improved morbidity and mortality of pulmonary hypertension patients.

Integrated Review of Psychosocial and Behavioral Health Assessments and Interventions in Pulmonary Hypertension

BACKGROUND

The medical management of patients with pulmonary hypertension (PH) has advanced, with few evidence-based recommendations about psychosocial and behavioral health interventions. There is also a lack of comprehensive understanding of PH psychosocial and behavioral health needs. Some psychosocial and behavioral health interventions have been tested; however, there is a gap in the systematic evaluation of nonpharmacological complementary approaches to augment PH management when addressing psychosocial and behavioral health needs.

OBJECTIVES

The objectives are to explore psychosocial and behavioral health needs and describe psychosocial and behavioral health interventions for patients with PH.

METHODS

We conducted an integrative systematic review of publications between January 1, 2010, and January 31, 2020, obtained from electronic databases: EMBASE, PubMed, Cumulative Index of Nursing and Allied Health Literature, Cochrane, PsycINFO, and Web of Science. The literature searches focused on empirical literature reporting psychosocial needs and psychosocial and behavioral health interventions for adult PH patients. We included peer-reviewed studies published in English. Search terms used in the study were: "hypertension," "pulmonary hypertension," "psychosocial," "depression," "anxiety," "quality of life," "behavioral health," "self-management," "psychosocial intervention," and "psychological distress." Excluded were opinion and discussion publications, reviews, non-PH populations, and pediatric articles. We used the constant comparison method to guide the synthesis of reports applying the Joanna Briggs quality assessment guidelines.

RESULTS

A total of 44 articles meeting the criteria were included for final consideration. We conducted an integrative systematic review of 27 quantitative studies, narrative synthesis of 10 qualitative studies, and 7 psychosocial and behavioral health intervention studies. PH patients reported psychosocial needs, such as financial, social connections, sexual health, and palliative care needs, as well as levels of psychological distress symptoms. The results from both quantitative and qualitative studies revealed similar overarching psychosocial and behavioral health conceptual categories. Patients described their ongoing needs in PH management by relying on their psychosocial and behavioral health capabilities to adjust to changes at each stage of disease progression. Patients had high levels of psychosocial and behavioral health needs requiring interventions beyond medical treatment.

DISCUSSION

Pilot studies testing psychosocial and behavioral health interventions reported improvement in levels of anxiety and depression and health-related quality of life. Larger scale studies are needed to advance this knowledge. Psychosocial and behavioral health interventions with cognitive-guided foci have the potential of meeting these unmet needs.

Implantable system for treprostinil: a real-world patient experience study

Parenteral prostanoids are effective for improving outcomes in patients with pulmonary arterial hypertension. However, subcutaneous or intravenous delivery via an external pump places a significant burden on patients. Consequently, the Implantable System for Remodulin© (treprostinil) was developed and is associated with a low rate of complications (United Therapeutics (Research Triangle Park, NC) in collaboration with Medtronic, Inc. (Mounds View, MN)). The current real-world experience study evaluated pulmonary arterial hypertension patients' perceptions of their quality of life, ability to perform activities of daily living, perceptions on the benefits and risks of the implantable system, and their social interactions before and after receiving the implantable system. Pulmonary arterial hypertension patients who had been transitioned from an external infusion pump to the implantable system completed a mix of quantitative and qualitative questions administered online over the course of a six-day period. A total of 20 patients completed the study. All patients reported that their quality of life, confidence out in public, and ability to travel long distances had improved. Over 90% of patients reported that their overall level of independence was better since receiving the implantable system, and most patients indicated that their ability to independently perform specific activities of daily living had improved. Responses to the qualitative questions suggested that the implantable system saved time, improved interpersonal relationships, and increased freedom. Results from this real-world patient experience study suggest this novel delivery system provides improvements in factors that are of substantial importance to patients.

Long-term health-related quality of life after surgery in patients with chronic thromboembolic pulmonary hypertension

PURPOSE

To assess the dynamic of various health-related quality of life (HRQoL) parameters 3 years after pulmonary thromboendarterectomy (PTE), and to identify factors affecting HRQoL parameters in patients with chronic thromboembolic pulmonary hypertension (CTEPH) in the long-term follow-up after surgery.

METHODS

This prospective cohort study included 128 patients with CTEPH before and after the PTE (3 year follow-up). The HRQoL was examined using the Short-Form 36 Health Survey Questionnaire (SF-36).

RESULTS

In patients with CTEPH 3 years after PTE, a significant improvement in all the HRQoL parameters. The summary indicators of the physical and mental components of health remained at the same level as 1 year after the PTE and did not exceed 50 points. The residual pulmonary hypertension was a leading factor limiting parameters of physical and mental health 3 years after a PTE. In addition, the parameters of physical activity were adversely affected by age and the age-adjusted Charlson Comorbidity Index.

CONCLUSIONS

In the study group of patients with CTEPH, PTE contributes to a significant improvement in all HRQoL parameters, which observed both 1 year and 3 years after surgery. The leading factor adversely affecting the physical and emotional components of health in the long-term period after PTE was residual pulmonary hypertension recorded in the early postoperative period. In addition, some physical HRQoL parameters are affected by age and age-adjusted Charlson Comorbidity Index.

Symptoms among emerging adults with inflammatory bowel disease: a descriptive study

Individuals with inflammatory bowel disease (IBD) are commonly diagnosed when they are between the ages of 18-29, a developmental period known as emerging adulthood. Typically, emerging adults are subsumed into the category of adults even though emerging adults have unique developmental needs. In this descriptive study of IBD in emerging adults, the aims were to (a) determine the prevalence of symptoms; (b) describe the severity of symptoms and their interference with daily activities; and (c) examine the association between individual symptom severity and presence of fatigue. Emerging adults with IBD were recruited using web-based convenience sampling. Sixty-one individuals met the inclusion criteria. They had a mean age of 24.7 and a disease duration of 6.4 years. The most prevalent symptoms reported were: fatigue (n = 44, 72.1%), abdominal cramps (n = 39, 63.9%), abdominal pain (n = 39, 63.9%), and diarrhea (n = 38, 62.3%). The symptom with the greatest severity and interference with daily activities was fatigue. Abdominal cramps, abdominal pain, diarrhea, passing gas, and abdominal tenderness were associated with fatigue when controlling for age, emerging adulthood, gender, time since diagnosis, and current steroid use. Among emerging adults with IBD, fatigue is the most prevalent symptom and is the symptom with the greatest severity and interference with daily activities. These results suggest a need for interventions aimed at reducing both fatigue and gastrointestinal symptoms among emerging adults with IBD.

Multidimensional fatigue in pulmonary hypertension: prevalence, severity and predictors

Pulmonary hypertension is a potentially fatal disease. Despite pharmacological advances in pulmonary hypertension, fatigue remains common in patients with pulmonary hypertension.

A convenience sample of 120 participants at an international patient conference completed the Multidimensional Fatigue Inventory (MFI)-20 scale. Data on New York Heart Association Functional Class, body mass index, oxygen use and medication type/use were also collected.

There was a high prevalence of “severe” to “very severe” fatigue for each dimension: General Fatigue (60%), Physical Fatigue (55.8%), Reduced Activity (41.7%), Reduced Motivation (32.5%) and Mental Fatigue (27.5%). The mean±sd overall MFI-20 score was 58±5.1. Dimensions with the highest averaged levels were General Fatigue (13.40±3.61), Physical Fatigue (13.23±3.67) and Reduced Activity (11.33±4.16). Body mass index correlated with higher fatigue scores. Phosphodiesterase inhibitor plus endothelin receptor antagonist combination negatively predicted General Fatigue, Physical Fatigue, Reduced Motivation and Reduced Activity. Triple therapy was a significant predictor of General Fatigue, Physical Fatigue and Reduced Activity. There were no significant predictors of Mental Fatigue.

Multidimensional fatigue is common and severe in patients with pulmonary hypertension. Phosphodiesterase inhibitor plus endothelin receptor antagonist combination resulted in lower scores in most fatigue dimensions. Comprehensive assessment of fatigue should be considered in the clinical care of patients with pulmonary hypertension and clinical research to develop formal interventions that target this disabling symptom.

Symptom severity and its effect on health-related quality of life over time in patients with pulmonary hypertension: a multisite longitudinal cohort study

Introduction

The aim of this cohort study was to examine health-related quality of life (HRQoL) and symptomatology in patients with pulmonary hypertension (PH) and explore factors that influence its evolution over time.

Methods

A prospective longitudinal multisite cohort study. Participants were recruited from specialist UK PH centres and completed a questionnaire pack at baseline, 6, 12 and 18 months to assess HRQoL (emPHasis-10), dyspnoea, fatigue, sleep, anxiety and depression.

Results

185 patients entered the study at baseline and 126 (68%) completed month 18. At baseline, patients had significant impairment of HRQoL, anxiety, depression, dyspnoea and severe fatigue. No significant changes, apart from a reduction in the Hospital Anxiety and Depression Scale-Anxiety score (P=0.04), were observed over 18 months. Depression and dyspnoea were predictors of HRQoL (P=0.002 and P=0.03, respectively). Oxygen use was also associated with diminished HRQoL and increased symptom severity.

Conclusion

Patients with PH experience high levels of symptom severity and the negative impact on HRQoL was unchanged over time. The use of oxygen therapy, in particular, was associated with a significant impact on HRQoL. Further study of factors impacting HRQoL and interventions that target a combination of physiological and psychosocial consequences of living with PH are needed.

Characterization of Prostacyclin-associated Leg Pain in Patients with Pulmonary Arterial Hypertension

RATIONALE

Prostacyclin-associated leg pain is a potentially debilitating adverse effect of prostacyclin therapy for patients with pulmonary arterial hypertension (PAH). However, to our knowledge, this entity has not been systematically studied.

OBJECTIVES

To characterize the clinical features and metabolic risk factors for prostacyclin-associated leg pain.

METHODS

At one academic medical center, we assembled and analyzed a case series of patients with PAH and prostacyclin-associated leg pain.

MEASUREMENTS AND MAIN RESULTS

Over a period of 2 years, we identified 11 patients with PAH and prostacyclin-associated leg pain who agreed to participate in this study. Subjects underwent a standardized clinical evaluation, electrodiagnostic assessment, and serologic screen for metabolic causes of peripheral neuropathy. All 11 patients were female; their mean (SD) age was 50 (±9) years; their median (interquartile range) PAH duration was 56 (20-96) months; and their prostacyclin therapy duration was a median (interquartile range) of 20 (14-36) months. All patients reported leg pain beginning soon after prostacyclin initiation and varying with dose. All described a neuropathic pain in a symmetric, distal, stocking distribution. Neurologic examination revealed a sensory, small-fiber, predominantly peripheral neuropathy in seven (78%) patients. Results of autonomic reflex testing and thermoregulatory sweat testing were abnormal in 82% and 90% of patients, respectively, suggesting small-fiber neuropathy. Serologic evaluation identified a new, previously unrecognized contributor to neuropathy in eight (73%) patients, including vitamin B₁₂ deficiency in six (55%), uncompensated hypothyroidism in three (27%), and diabetes mellitus in one (9%).

CONCLUSIONS

Chronic prostacyclin-associated leg pain is associated with a small-fiber neuropathy. Treatable metabolic contributors (vitamin B₁₂ deficiency, thyroid dysfunction, or diabetes) appear to be common possible "second hits" that may be underrecognized. We recommend screening for possible metabolic contributors in patients who have otherwise unexplained leg pain in the setting of PAH and current or anticipated prostacyclin therapy.

Safety and effectiveness of tadalafil in patients with pulmonary arterial hypertension: Japanese post-marketing surveillance data

OBJECTIVE

To evaluate the long-term safety and effectiveness of tadalafil in patients with pulmonary arterial hypertension (PAH) in real-world clinical practice.

METHODS

This prospective, multicenter, noninterventional, post-marketing surveillance included patients with PAH who were observed for up to 2 years after initiation of tadalafil. Safety was assessed by analyzing the frequency of adverse drug reactions (ADRs), discontinuations due to adverse events (AEs), and serious adverse drug reactions (SADRs). Effectiveness measurements included the assessment of the change in World Health Organization (WHO) functional classification of PAH, 6-minute walk test, cardiac catheterization, and echocardiography.

RESULTS

Among 1676 patients analyzed for safety, the overall incidence of ADRs was 31.2%. The common ADRs (≥1.0%) were headache (7.0%), diarrhea (1.9%), platelet count decreased (1.8%), anemia, epistaxis, and nausea (1.6% each), flushing (1.3%), hepatic function abnormal (1.1%), hot flush, and myalgia (1.0% each). The common SADRs (≥0.3%) were cardiac failure (0.7%), interstitial lung disease, worsening of PAH, and platelet count decreased (0.3% each). Among 1556 patients analyzed for effectiveness, the percentages of patients with improvement of WHO functional class at 3 months, 1 year, and 2 years after the initiation of tadalafil, and last observation were 17.1%, 24.8%, 28.9%, and 22.5%, respectively. At all observation points (except pulmonary regurgitation pressure gradient at end diastole at 3 months), the mean 6-minute walk distance, cardiac catheterization, and echocardiogram measurements showed statistically significant improvement.

CONCLUSION

This surveillance demonstrated that tadalafil has favorable safety and effectiveness profiles for long-term use in patients with PAH in Japan.

Systematic Review of Health-Related Quality of Life in Patients with Pulmonary Arterial Hypertension

BACKGROUND

The increasing survival of patients with pulmonary arterial hypertension (PAH) has shifted attention towards the disease burden that PAH imposes on patients and healthcare systems. Most studies emphasize epidemiology and medications, while large observational studies reporting on the health-related quality of life (HRQOL) of patients with PAH are lacking.

OBJECTIVE

Our objective was to study the HRQOL of patients with PAH and to summarize the factors that influence it.

METHODS

We conducted systematic literature searches in English (PubMed, Web of Knowledge, ScienceDirect and OVID) and Chinese (China National Knowledge Infrastructure, Wanfang Data, Chongqing VIP and SinoMed) databases to identify studies published from 2000 to 2015 assessing the HRQOL of patients with PAH. Search results were independently reviewed and extracted by two reviewers.

RESULTS

Of 3392 records identified in the initial search, 20 eligible papers (19 English, 1 Chinese) were finally included. Studies used a range of instruments; the generic 36-item Short Form Survey (SF-36) was the most widely used, and the disease-specific Cambridge Pulmonary Hypertension Outcome Survey (CAMPHOR) was the second mostly widely used. Mean HRQOL scores assessed via the SF-36 (physical component summary [PCS] 25.4-80.1; mental component summary [MCS] 33.2-76.0) and CAMPHOR (symptom scores 3.1-17; total HRQOL 2.8-12.6; activity scores 3.8-18.1) varied across studies, reporting decreased HRQOL in patients. Mental health (depression, anxiety, stress), physical health (exercise capacity, symptoms) and medical therapies were reported to affect HRQOL.

CONCLUSION

We found that PAH places a substantial burden on patients, particularly in terms of HRQOL; however, the paucity of large observational studies in this area requires the attention of researchers, especially in China.

Pulmonary Hypertension and Palliative Care: What, When, Where, and Why?

Summary:

Pulmonary hypertension (PH) can be associated with a high level of symptom burden from the disease as well as its treatment. Involvement of palliative care (PC) services may help facilitate discussion regarding goals of care, prognostic planning, and treatment options focused on improving quality of life (QOL).

Background:

PC is active total care of a patient whose disease is not fully responsive to curative therapies, with symptom control as the top priority. After a life-limiting diagnosis is made, health care teams and patients determine prognosis, whether cure is attainable or reasonable, what treatment options are available, risks and benefits of associated treatments, and how treatment or nontreatment will impact QOL and survival. QOL is often the focus of palliative interventions, with the goal to minimize symptoms and empower patients with accurate information to help affirm life and meet objectives of care.

Implications for clinicians:

PC can begin at the onset of symptoms in a disease that cannot be cured. Early PC may help facilitate discussion regarding goals of care when patient expectations are discordant with prognosis. While PC is a responsibility of all clinicians, subspecialist assistance can be helpful when a clinical decline occurs, in the setting of uncertainty, when patients are removed from the transplant list, or when long-term QOL issues are present.

Conclusion:

Communication with patients who have PH can be delicate and requires an understanding of the disease's process, trajectory, and prognosis. PC teams possess communication skills that may benefit patients and providers with QOL optimization, delivery of difficult news, advanced care planning, and shared decision-making.
