The diagnostic pathway for patients with interstitial lung disease: a mixed-methods study of patients and physicians.

OBJECTIVES: The diagnostic process for patients with interstitial lung diseases (ILD) remains complex. The aim of this study was to characterise the diagnostic care pathway and identify barriers and potential solutions to access a timely and accurate ILD diagnosis. DESIGN: This mixed-method study was comprised of a quantitative chart review, patient and physician surveys and focus groups. RESULTS: Chart review was completed for 97 patients. Median time from symptom onset to ILD diagnosis was 12.0 (IQR 20.5) months, with 46% diagnosed within 1 year. Time from first computed tomography (CT) scan to respirology referral was 2.4 (IQR 21.2) months. Referrals with a prior CT were triaged sooner than referrals without (1.7±1.6 months vs 3.9±3.3 months, p=0.013, 95% CI 0.48 to 2.94). On patient surveys (n=70), 51% felt that their lung disease was not recognised early enough. Commonly reported challenges to timely diagnosis included delayed presentation to primary care, initial misdiagnoses and long wait-times for specialists. Forty-five per cent of physicians (n=20) identified diagnostic delays, attributed to delayed presentations to primary care (58%), initial misdiagnoses (67%) and delayed chest imaging (75%). Themes from patient and respirologist focus groups included patient-related, healthcare provider-related and system-related factors leading to delays in diagnosis. CONCLUSIONS: This mixed-methods study identified patient and system-related factors that contribute to diagnostic delays for patients with ILD, with most delays occurring prior to respirology referral. ILD awareness and education, earlier presentation to primary care, expedited access to chest imaging and earlier referral to respirology may expedite diagnosis.

Use of 6-minute walk distance to predict lung transplant-free survival in fibrosing non-IPF interstitial lung diseases.

BACKGROUND AND OBJECTIVE: The identification of progression in patients with fibrosing non-idiopathic pulmonary fibrosis (IPF) interstitial lung diseases (ILDs) represents an ongoing clinical challenge. Lung function decline alone may have significant limitations in the detection of clinically significant progression. We hypothesized that longitudinal changes of 6-min walk distance (6MWD) from baseline, simultaneously considered with measures of lung function, may independently predict survival and identifying clinically significant progression of disease. METHODS: Forced vital capacity (FVC), diffusing lung capacity (DLCO) and 6MWD were considered both at baseline and at 1 year in a discovery cohort (n = 105) and in a validation cohort (n = 138) from different centres. The primary endpoint was lung transplant (LTx)-free survival. RESULTS: Average follow-up was 3 years in both cohorts. Combined incidence of deaths and LTx was 29% and 21%, respectively. No collinearity and no strong correlations were observed among FVC, DLCO and 6MWD longitudinal changes. While age, gender and BMI were not significant, 6MWD decline ≥24 m predicted LTx-free-survival significantly and independently from FVC and DLCO declines, with high sensitivity and specificity, in both the discovery and the validation cohorts. Although FVC and DLCO declines remained significant predictors of LTx-free survival, 6MWD decline was more accurate than the proposed ATS/ERS/JRS/ALAT functional criteria. Results were confirmed after stratifying patients by baseline FVC. CONCLUSION: Longitudinal declines of 6MWD are associated with poor survival in fibrosing ILDs across a wide range of baseline severity, with high accuracy. 6MWD longitudinal decline is largely independent from lung function decline and may be integrated into the routine assessment of progression.

The Impact of Integrated Palliative Care on Survival in Idiopathic Pulmonary Fibrosis: A Retrospective Multicenter Comparison.

Background: Early and integrated palliative care is recommended for patients with idiopathic pulmonary fibrosis. Unfortunately, palliative care delivery remains poor due to various barriers in practice. This study describes various palliative care delivery models in a real-world cohort of patients with idiopathic pulmonary fibrosis, examines the predictors of survival in this cohort of patients, and explores the impact of palliative care on survival. Design: Charts were reviewed retrospectively and analyzed. The primary outcome was survival during a 4-year follow-up period. Two multivariable models were created to examine the impact of therapeutic strategies including palliative intervention on survival. Results: 298 patients with idiopathic pulmonary fibrosis were enrolled from 3 interstitial lung disease clinics with different palliative care models in Edmonton, Canada; Bristol, UK; and Kingston, Canada. 200 (67%) patients received palliative care and 119 (40%) died during follow up. Primary palliative care models (Edmonton and Bristol) delivered palliative care to 96% and 100% respectively compared 21% in the referral model (Queens). Palliative care [adjusted hazard ratio (aHR) .28 (.12-.65)] along with the use of antifibrotics [aHR .56 (.37-.84)], and body mass index >30 [aHR .47 (.37-.85)] reduced the risk of death in our idiopathic pulmonary fibrosis cohort. Opioid use was associated with worse survival [aHR 2.11 (1.30-23.43)]. Conclusions: Both palliative care and antifibrotic use were associated with survival benefit in this cohort of patients with idiopathic pulmonary fibrosis after adjusting for covariates. The benefit was seen despite differences in disease severity and different palliative care delivery models.

Validation of a Novel Clinical Dyspnea Scale - A Retrospective Pilot Study.

Objective: to examine the validity of a novel dyspnea scale, Edmonton Dyspnea Inventory in idiopathic pulmonary fibrosis (IPF). Methods: Edmonton Dyspnea Inventory (EDI), is a clinical instrument to measure dyspnea severity with activities of daily living, exercise and rest using a numeric rating scale (0 -10). Consecutive IPF patients (2012-2018) with baseline MRC and EDI were included. To validate EDI, psychometric analysis was conducted. Correlations between EDI, MRC and lung function were examined. Group-based trajectory modeling was used to group patients based on dyspnea severity. Net Reclassification Improvement (NRI) was calculated to assess the improvement in 1-year mortality prediction by adding trajectory groups to MRC grade. Results: 100 consecutive IPF patients were identified; mean age 73 years (SD = 9) and 65% males; 73% were in MRC grades ≥3. Item analysis showed all 8 EDI components have excellent discrimination power with ability to differentiate patients with varying dyspnea severity. EDI has good internal consistency (Cronbach α = .92). Exploratory factor analysis showed a one-factor solution with loadings from .66 to .89 suggesting 8 EDI components measured essentially one dimension of dyspnea. All EDI components were correlated with MRC and some with lung function. Modeling data identified three EDI dyspnea severity groups with differing mortality (P = .009). The addition of EDI dyspnea severity groups to the MRC score improved 1-year mortality prediction (NRI = .66; 95% CI, .18-1.14). Conclusions: EDI is a valid dyspnea instrument, correlated with MRC and lung function. It can categorize IPF patients into 3 dyspnea severity groups associated with increased mortality. Key Message: We describe the development of a novel scale, Edmonton Dyspnea Inventory, that facilitates measurement of dyspnea severity in the context of daily activities in patients with IPF. The results indicate that the new instrument is valid and correlated to MRC. It identifies 3 categories of severity not recognized by MRC with impact on mortality. Knowledge of dyspnea severity can help triage patients and assign appropriate therapies.

A Retrospective, Descriptive Study of Dyspnea Management in a Multidisciplinary Interstitial Lung Disease Clinic.

Background: Fibrotic interstitial lung diseases (F-ILDs) have a high symptom burden with progressive dyspnea as a primary feature. Breathlessness is underrecognized and undertreated primarily due to lack of consensus on how to best measure and manage it. Several nonpharmacologic and pharmacologic strategies are published in the literature, however there is a paucity of real-world data describing their systematic implementation. Objectives: We describe the types of breathlessness interventions and timing of implementation in our multidisciplinary collaborative care (MDC) ILD clinic and the impact of our approach on dyspnea trajectory and acute care use in ILD. Methods: A retrospective, observational study of deceased ILD patients seen in our clinic (2012-2018) was conducted. Patients were grouped by baseline medical research council (MRC) grade and dyspnea interventions from clinic enrolment until death were examined. Healthcare usage in the last 6 months of life was collected through Alberta's administrative database. Results: Eighty-one deceased ILD patients were identified. Self management advice was provided to 100% of patients. Pulmonary rehabilitation (PR) and home care (HC) referrals were made in 40% and 57% of patients, respectively. Eighty percent were treated with oxygen and 53% with opioids during the study. MDC-initiated referral to PR and HC, oxygen and opioid prescriptions were provided a median of 13, 9, 11, and 4 months prior to death, respectively. Stepwise implementation of interventions was observed more commonly in MRC 1-2 and concurrent implementation in MRC 4-5. Conclusions: Our clinic's approach allows early and systematic dyspnea management.

Redesigning interstitial lung disease clinic care through interprofessional collaboration.

Descriptions of how to foster and accomplish interprofessional collaboration (IPC) in practice across different healthcare settings are needed. This paper examines the transformation of a normative interstitial lung disease (ILD) clinic to an IPC delivering person-centric care across an outpatient specialty clinic and the community. It describes how the IPC was started; the actions undertaken to do this; and the processes supporting it within the outpatient clinic, and between it and its community-based partners. Qualitative research methods (participants-as-co-researchers, unstructured interviews, thematic content analysis) were used with the two physicians founding the IPC to understand this transformation process; this is supplemented with preliminary findings of interviews with patients/carers (N = 30) attending the outpatient clinic. Analysis suggests the power of IPC to improve patients' quality of life and death, reduce acute care use and hospitalization, and realize patient preferences for location of death. Despite this, the ILD IPC encounters resistance from larger institutional and political forces.

Advance Care Planning Needs in Idiopathic Pulmonary Fibrosis: A Qualitative Study.

INTRODUCTION: Advance care planning is recommended in chronic respiratory diseases, including Idiopathic Pulmonary Fibrosis. In practice, uptake remains low due to patient, physician and system-related factors, including lack of time, training and guidance on timing, components and content of conversations. Our aim was to explore perspectives, experiences and needs to inform a framework. METHODS: We conducted a qualitative study in western Canada, using semi-structured interviews and inductive analysis. Patient, caregiver and health care professional participants described advance care planning experiences with Idiopathic Pulmonary Fibrosis. RESULTS: Twenty participants were interviewed individually: 5 patients, 5 caregivers, 5 home care and 5 acute care health care professionals. Two categories, perceptions and recommendations, were identified with themes and subthemes. Participant perceptions were insufficient information and conversations occur late. Recommendations were: have earlier conversations; have open conversations; provide detailed information; and plan for end-of-life. Patients and caregivers wanted honesty, openness and clarity. Professionals related delayed timing to poor end-of-life care and distressing deaths. Home care professionals described comfort with and an engaged approach to advance care planning. Acute care professionals perceived lack of clarity of roles and described personal, patient and caregiver distress. INTERPRETATION: Analysis of diverse experiences provided further understanding of advance care planning in Idiopathic Pulmonary Fibrosis. Advance care planning is desired by patients and caregivers early in their illness experience. Health care professionals described a need to clarify role, scope and responsibility. Practical guidance and training must be available to care providers to improve competency and confidence in these conversations.

Patient-reported outcomes and patient-reported outcome measures in interstitial lung disease: where to go from here?

Patient-reported outcome measures (PROMs), tools to assess patient self-report of health status, are now increasingly used in research, care and policymaking. While there are two well-developed disease-specific PROMs for interstitial lung diseases (ILD) and idiopathic pulmonary fibrosis (IPF), many unmet and urgent needs remain. In December 2019, 64 international ILD experts convened in Erice, Italy to deliberate on many topics, including PROMs in ILD. This review summarises the history of PROMs in ILD, shortcomings of the existing tools, challenges of development, validation and implementation of their use in clinical trials, and the discussion held during the meeting. Development of disease-specific PROMs for ILD including IPF with robust methodology and validation in concordance with guidance from regulatory authorities have increased user confidence in PROMs. Minimal clinically important difference for bidirectional changes may need to be developed. Cross-cultural validation and linguistic adaptations are necessary in addition to robust psychometric properties for effective PROM use in multinational clinical trials. PROM burden of use should be reduced through appropriate use of digital technologies and computerised adaptive testing. Active patient engagement in all stages from development, testing, choosing and implementation of PROMs can help improve probability of success and further growth.

Action plans in idiopathic pulmonary fibrosis: a qualitative study-'I do what I can do'.

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a progressive, incurable fibrotic lung disease in which patients and caregivers report a high symptom burden. Symptoms are often poorly managed and patients and caregivers struggle to alleviate their distress in the absence of self-management support. AIM: To explore perceptions of symptoms, symptom management strategies and self-efficacy for patients with IPF and caregivers who received self-management education and action plans created and provided in a Multidisciplinary Collaborative Interstitial Lung Disease (MDC-ILD) Clinic. DESIGN: A qualitative study was conducted with participants recruited from the MDC-ILD Clinic. Participants received an early integrated palliative approach; most attended ILD pulmonary rehabilitation and some received home care support. Semistructured interviews were conducted. Patient participants completed Measure Yourself Medical Outcome Profile (MYMOP) for symptom assessment and Chronic Obstructive Pulmonary Disease Self-Efficacy Scale to assess self-management efficacy. RESULTS: Thirteen patients and eight self-declared caregiver participants were interviewed. IPF severity ranged from mild to advanced disease. Participants integrated and personalised self-management strategies. They were intentional and confident, focused on living well and engaged in anticipatory planning. Twelve participants completed the MYMOP. Five reported dyspnoea. Four reported fatigue as an additional or only symptom. One reported cough. Five declared no dyspnoea, cough or fatigue. Participants reported 80% self-efficacy in symptom management. CONCLUSIONS: The approach to symptom self-management and education was beneficial to patients with IPF and caregiver participants. Participants personalised the strategies, focusing on living, and planned both in the moment and for the future. They were confident and expressed dignity and meaning in their lives.

Idiopathic pulmonary fibrosis beyond the lung: understanding disease mechanisms to improve diagnosis and management.

Idiopathic pulmonary fibrosis (IPF) is a chronic and progressive disorder with an estimated median survival time of 3-5 years after diagnosis. This condition occurs primarily in elderly subjects, and epidemiological studies suggest that the main risk factors, ageing and exposure to cigarette smoke, are associated with both pulmonary and extrapulmonary comorbidities (defined as the occurrence of two or more disorders in a single individual). Ageing and senescence, through interactions with environmental factors, may contribute to the pathogenesis of IPF by various mechanisms, causing lung epithelium damage and increasing the resistance of myofibroblasts to apoptosis, eventually resulting in extracellular matrix accumulation and pulmonary fibrosis. As a paradigm, syndromes featuring short telomeres represent archetypal premature ageing syndromes and are often associated with pulmonary fibrosis. The pathophysiological features induced by ageing and senescence in patients with IPF may translate to pulmonary and extrapulmonary features, including emphysema, pulmonary hypertension, lung cancer, coronary artery disease, gastro-oesophageal reflux, diabetes mellitus and many other chronic diseases, which may lead to substantial negative consequences in terms of various outcome parameters in IPF. Therefore, the careful diagnosis and treatment of comorbidities may represent an outstanding chance to improve quality of life and survival, and it is necessary to contemplate all possible management options for IPF, including early identification and treatment of comorbidities.

Early Integrated Palliative Care Bundle Impacts Location of Death in Interstitial Lung Disease: A Pilot Retrospective Study.

BACKGROUND: Interstitial lung diseases (ILDs) comprise a heterogeneous group of fibrotic, progressive pulmonary diseases characterized by poor end-of-life care and hospital deaths. In 2012, we launched our Multidisciplinary Collaborative (MDC) ILD clinic to deliver integrated palliative approach throughout disease trajectory to improve care. We sought to explore the effects of palliative care and other factors on location of death (LOD) of patients with ILD. METHODS: The MDC-ILD clinic implemented a palliative care bundle including advance care planning (ACP), opiates use, allied health home care engagement, and use of supplemental oxygen and early caregiver engagement in care. Data from patients with ILD who attended the clinic and died between 2012 and 2019 were used to generate scores representing the components and duration of palliative care (palliative care bundle score) and caregiver involvement (caregiver engagement score). We examined the impact of these scores on patients' LOD. RESULTS: A total of 92 MDC-ILD clinic patients were included, 57 (62%) had home or hospice deaths. Patients who died at home or hospice had higher palliative care bundle scores (10.0 ± 4.0 vs 7.8 ± 3.9, P = .01) and caregiver engagement scores (1.7 ± 0.6 vs 1.3 ± 0.7, P = .01) compared to those who died in hospital. Patients were 1.13 times more likely to die at home or hospice following a 1-point increase in palliative care bundle score (95% CI: 1.01-1.29, P = .04) and 2.38 times more likely following a 1-point increase in caregiver engagement score (95% CI: 1.17-5.15, P = .02). CONCLUSIONS: Home and hospice deaths are feasible in ILD. Early initiation of palliative care bundle components such as ACP discussions, symptom self-management, caregiver engagement, and close collaboration with allied health home care supports can promote adherence to patient preference for home or hospice deaths.

Buccal Hydromorphone Syrup for Managing Dyspnea in Idiopathic Pulmonary Fibrosis.

CONTEXT: Dyspnea is a highly distressing symptom that characterizes idiopathic pulmonary fibrosis (IPF), a common idiopathic interstitial lung disease (ILD) with a high symptom burden, poor quality of life, and early mortality. Though opioids are mentioned in guidelines for dyspnea management, guidance on how and when to initiate opioids is lacking. Different pharmacologic strategies are needed to address different types of dyspnea (baseline, incident, and crisis). Due to a longer onset of action, the oral route (swallowed) may be less effective for prevention of incident dyspnea or for rapid relief of crisis dyspnea, prompting the use of alternative drug delivery strategies for self-management. We inadvertently discovered the efficacy of buccal administration of low dose, low volume hydromorphone oral syrup for dyspnea management in ILD, which has not been previously reported in the literature. CASE SERIES: We describe our approach to dyspnea assessment and management in IPF, including use of the Multidimensional Dyspnea Scale (MDDS), a novel instrument yet to be validated that we developed to better identify and categorize dyspnea into the types experienced by a patient with IPF over the course of a day. We then describe how buccal hydromorphone oral syrup is initiated and titrated for dyspnea management in 3 patients at different points in their disease trajectory. CONCLUSION: Buccal hydromorphone oral syrup is effective for dyspnea management across the spectrum of IPF. When integrated into a patient-centered algorithm for symptom assessment and management, it allows for rapid and easy self-management of dyspnea by patients and their caregivers.

Health Care Costs at the End of Life for Patients with Idiopathic Pulmonary Fibrosis. Evaluation of a Pilot Multidisciplinary Collaborative Interstitial Lung Disease Clinic.

Rationale: Even though idiopathic pulmonary fibrosis (IPF) is a disease with high morbidity and mortality and no cure, palliative care is rarely implemented, leading to high symptom burden and unmet care needs. In 2012, we implemented a multidisciplinary collaborative (MDC) care model linking clinic and community multidisciplinary teams to provide an early integrated palliative approach, focusing on early symptom management and advance care planning.Objectives: To evaluate the differences in resource use and associated costs of end-of-life care between patients with IPF who received early integrated palliative care and patients with IPF who received conventional treatment.Methods: Using administrative health data, we identified all patients in the Province of Alberta, Canada, who presented to a hospital with an IPF diagnosis between January 1, 2012, and December 31, 2018, and died within this time frame. We compared three groups of patients: those who received MDC care (our clinic patients), specialist care (SC; respirologist), or non-specialist care (NSC; no contact with a respiratory clinic). The primary outcomes were healthcare resource use and costs in the year before death.Results: Of 2,768 patients across the three study groups, in the last year of life, MDC patients were more than three times as likely as SC patients to have received antifibrotic therapies (odds ratio [OR], 3.0; 95% confidence interval [CI], 1.8-5.2), almost twice as likely to have received pulmonary rehabilitation (OR, 1.9; 95% CI, 1.1-3.4), and 36% more likely to have received opiates (OR, 1.4; 95% CI, 0.8-2.3). The median total healthcare costs in the last 3 months of life were approximately C$7,700 lower for MDC patients than for those receiving SC, driven primarily by fewer hospitalizations and emergency department visits. MDC patients were also less likely to die in the hospital (44.9% MDC vs. 64.9% SC vs. 66.8% NSC; P < 0.001) and had the highest rates of no hospitalization in the last year of life.Conclusions: An integrated palliative approach in IPF is associated with improvements in the quality of end-of-life care and reduction in costs. Transformation of care models is required to deliver palliative care for patients with IPF. MDC teams within such models can address the high burden of unmet needs for symptom management, advance care planning, and community support in this complex population.

What Patients With Idiopathic Pulmonary Fibrosis and Caregivers Want: Filling the Gaps With Patient Reported Outcomes and Experience Measures.

Idiopathic pulmonary fibrosis is a progressive disease, with a high mortality within the first 3-5 years from diagnosis and a poor quality of life mainly because of the burden of symptoms, such as dyspnea and cough, occurring usually many months before the diagnosis. Although available antifibrotic therapies slow down disease progression, they have no impact on quality of life. Moreover, health care around idiopathic pulmonary fibrosis patients is often "disease-centered" and relies on clinical surrogate outcomes that are poorly related to patients' quality of life and disease experience. Therefore, patients with idiopathic pulmonary fibrosis have several unmet needs in all domains of health that they wish to see recognized and addressed in the context of the treatment of their disease and its complications. In this review, we summarize the care pathway from the patients' perspective, identifying current gaps in care, education, support, and communication among patients with IPF, their caregivers, and care teams during the patient journey. The role of patient-reported outcomes (PROs), PRO measures (PROMs), and patient-reported experience measures (PREMs) in their care is discussed, as well as the need of disease-specific PROs, PROMs, and PREMs.

A comprehensive and practical approach to the management of idiopathic pulmonary fibrosis.

Introduction: Idiopathic pulmonary fibrosis (IPF) is a debilitating, progressive, and fatal fibrotic pulmonary disease with a prognosis comparable to that of lung cancer. IPF management is a complex process that involves pharmacological and nonpharmacological interventions, extensive patient education, and addressing patient needs that change through the course of the illness. Areas covered: This review summarizes the key aspects of a multifaceted, multidisciplinary, individualized approach to IPF care that incorporates available treatment options, strategies to improve compliance with antifibrotic therapies, pulmonary rehabilitation, and the integration of palliative care for symptom management. Aspects of care discussed include the use of antifibrotic therapy and nonpharmacological treatments, targeted education and psychosocial support, evaluation and management of comorbidities, and early integration of palliative care. Expert opinion: By incorporating this comprehensive approach to disease management, physicians can address most aspects of care for a patient with IPF to optimize survival and quality of life.

Early integrated palliative approach for idiopathic pulmonary fibrosis: A narrative study of bereaved caregivers' experiences.

BACKGROUND: Idiopathic pulmonary fibrosis has an uncertain and rapid trajectory after diagnosis. Palliative care is rarely utilized, although both patients and caregivers experience a distressingly high symptom burden. Most patients die in hospital. AIM: The purpose of this study was to explore bereaved caregivers' experiences and perceptions of an early integrated palliative approach implemented at a Multidisciplinary Interstitial Lung Disease Clinic. DESIGN: A narrative approach was used, with thematic and content analysis of open-ended interviews. SETTING/PARTICIPANTS: The clinic is located in a large western Canadian city. Caregivers of deceased patients were recruited through purposive sampling. The eight participants were either spouses or adult children. RESULTS: Five major themes were identified: Having a Terminal Disease; Planning Goals and Wishes for Care; Living Life and Creating Memories; Feeling Strain and Responsibility; and Nearing the End. Caregivers had little understanding of prognosis prior to advance care planning conversations at the clinic. Advance care planning conversations enabled caregivers to know and support patients' goals and wishes. Caregivers described feeling informed, prepared, and supported when death was near. They expressed neither distress nor anxiety related to patients' symptoms or strain of relationships. CONCLUSION: Collaboration and close communication among caregivers, respirologists, and home care enabled effective symptom management and out of hospital deaths. Patients and caregivers had opportunities to enjoy events, create memories, determine preferences, and make plans. Further research on an early integrated palliative approach in Idiopathic Pulmonary Fibrosis is warranted related to quality of life, experience with death and dying, and caregiver bereavement.
