Essential Components of an Interstitial Lung Disease Clinic: Results From a Delphi Survey and Patient Focus Group Analysis.
BACKGROUND: Management of patients with interstitial lung disease (ILD) requires subspecialized, comprehensive, multidisciplinary care. The Pulmonary Fibrosis Foundation established the Care Center Network (CCN) in 2013 with identified criteria to become a designated CCN site. Despite these criteria, the essential components of an ILD clinic remain unknown. RESEARCH QUESTIONS: How are ILD clinics within the CCN structured? What are the essential components of an ILD clinic according to ILD physician experts, patients, and caregivers? STUDY DESIGN AND METHODS: This study had three components. First, all 68 CCN sites were surveyed to determine the characteristics of their current ILD clinics. Second, an online, three-round modified Delphi survey was conducted between October and December 2019 with 48 ILD experts participating in total. Items for round 1 were generated using expert interviews. During rounds 1 and 2, experts rated the importance of each item on a 5-point Likert scale. The a priori threshold for consensus was more than 75% of experts rating an item as important or very important. In round 3, experts graded items that met consensus and ranked items deemed essential for an ILD clinic. Third, ILD patient and caregiver focus groups were conducted and analyzed for content to determine their perspectives of an ideal ILD clinic. RESULTS: Forty items across four categories (members, infrastructure, resources, and multidisciplinary conference) achieved consensus as essential to an ILD clinic. Patient and caregiver focus groups identified three major themes: comprehensive, patient-centered medical care; expanded access to care; and comprehensive support for living and coping with ILD. INTERPRETATION: The essential components of an ILD clinic are well-aligned between physician experts and patients. Future research can use these findings to evaluate the impact of these components on patient outcomes and to inform best practices for ILD clinics throughout the world
Idiopathic pulmonary fibrosis: Educational needs of health-care providers, patients, and caregivers
Informal caregivers experience of supplemental oxygen in pulmonary fibrosis
Abstract Background Patients prescribed supplemental oxygen (O2) therapy face challenges as they adjust to being constantly “tethered” to an oxygen delivery device. Informal caregivers (ICs) of patients with pulmonary fibrosis (PF) face their own, often overlooked hardships when O2 is brought into their home and added to their lives. Our aim was to understand the multiple effects of supplemental oxygen therapy on ICs of patients with PF. Methods We conducted single, semi-structured telephone interviews with twenty ICs of patients with PF who were using O2 for at least 8 months. We performed a qualitative, content analysis based in grounded theory to examine data across subjects. Results ICs initially reacted to O2 with trepidation and sadness as they came to recognize the changes it would cause in the lives of their patient-loved one (PLO). ICs recognized both beneficial and negative effects of O2 on their PLOs. ICs also realized that O2 created significant changes in their own lives, including introducing new roles and responsibilities for them, altering their home environments and significantly impacting their relationships with their PLOs. Although O2 was a tangible and constant reminder of disease progression, over time ICs were able to adapt and accept their new lives with O2. Conclusion ICs of patients with PF experience many life changes when their PLO is prescribed O2. Having O2 prescribers anticipate and recognize these challenges provides an opportunity to give support and guidance to ICs of PF patients who require O2 in the hopes of limiting the negative impact of O2 on their lives.

Tracking dyspnea up to supplemental oxygen prescription among patients with pulmonary fibrosis
Abstract Background Dyspnea is the hallmark symptom of pulmonary fibrosis. Supplemental oxygen (O2) is prescribed to many patients with pulmonary fibrosis in hopes of alleviating dyspnea and improving physical functioning. We used response data from the University of California San Diego Shortness of Breath Questionnaire (UCSD) which was administered monthly in the context of a longitudinal, observational study to plot a rich trajectory for dyspnea over time in patients with pulmonary fibrosis. We used other data from that study to identify clinical predictors of being prescribed O2 and to provide additional information for how UCSD scores could be used for clinical purposes. Methods We used linear mixed-effects models and multivariate Cox proportional hazards to model change in dyspnea scores over time and to identify significant predictors of time-to-O2-prescription among a pool of clinically-meaningful candidate variables. In the longitudinal study, all decisions, including whether or not to prescribe O2, were made by subjects’ treating physicians, not members of the research team. Results One-hundred ninety-four subjects with pulmonary fibrosis completed more than one UCSD or were prescribed O2 at some point during the follow-up period (N = 43). Twenty-eight of the 43 had analyzable, longitudinal data and contribute data to the longitudinal UCSD analyses. All 43 were included in the time-to-O2-prescription analyses. Subjects prescribed O2 had more severe dyspnea at enrollment (38.4 ± 19.6 vs. 22.6 ± 18.7, p < 0.0001) and a steeper increase in UCSD scores over time (slope = 1.18 ± 0.53 vs. 0.24 ± 0.09 points per month, p = 0.02) than subjects not prescribed O2. Controlling for baseline UCSD score and FVC%, subjects with a clinical summary diagnosis of idiopathic pulmonary fibrosis (IPF) were far more likely to be prescribed O2 than subjects with other forms of pulmonary fibrosis (hazard ratio = 4.85, (2.19, 10.74), p < 0.0001). Conclusions Baseline dyspnea and rise in dyspnea over time predict timing of O2 prescription. Accounting for disease severity, patients with IPF are more likely than patients with other forms of pulmonary fibrosis to be prescribed O2. UCSD scores provide clinically useful information; frequent administration could yield timely data on changes in disease status in patients with pulmonary fibrosis. Trial registration The longitudinal study is registered on ClinicalTrials.gov ( NCT01961362 ). Registered October 9, 2013
Physical activity and activity space in patients with pulmonary fibrosis not prescribed supplemental oxygen
Abstract Background Patients with pulmonary fibrosis (PF) have impaired quality of life, and research suggests that dyspnea and physical activity are primary drivers. As PF progresses, some patients notice the disease “shrinks their worlds”. The objective of this study is to describe movement (both physical activity and activity space) in a cohort of patients with PF of various etiologies who have not been prescribed supplemental oxygen (O2). Methods Subjects with PF not on supplemental O2 during the day were enrolled from across the U.S. from August 2013 to October 2015. At enrollment, each subject completed questionnaires and, for seven consecutive days, wore an accelerometer and GPS tracker. Results One hundred ninety-four subjects had a confirmed diagnosis of PF and complete, analyzable GPS data. The cohort was predominantly male (56%), Caucasian (95%) and had idiopathic pulmonary fibrosis (30%) or connective tissue disease related-PF (31%). Subjects walked a median 7497 (interquartile range [IQR] 5766-9261) steps per day. Steps per day were correlated with symptoms and several quality of life domains. In a model controlling for age, body mass index, wrist- (vs. waist) worn accelerometer and percent predicted diffusing capacity (DLCO%), fatigue (beta coefficient = −51.5 ± 11.7, p < 0.0001) was an independent predictor of steps per day (model R2=0.34). Conclusions Patients with PF, who have not been prescribed O2 for use during the day, have wide variability in their mobility. Day-to-day physical activity is related to several domains that impact quality of life, but GPS-derived activity space is not. Wearable data collection devices may be used to determine whether and how therapeutic interventions impact movement in PF patients. Trial registration NCT01961362 . Registered 9 October, 2013

Home oxygen therapy for adults with chronic lung disease an official american thoracic society clinical practice guideline
Background: Evidence-based guidelines are needed for effective delivery of home oxygen therapy to appropriate patients with chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD). Methods: The multidisciplinary panel created six research questions using a modified Delphi approach. A systematic review of the literature was completed, and the Grading of Recommendations Assessment, Development and Evaluation approach was used to formulate clinical recommendations. Recommendations: The panel found varying quality and availability of evidence and made the following judgments: 1) strong recommendations for long-term oxygen use in patients with COPD (moderate-quality evidence) or ILD (low-quality evidence) with severe chronic resting hypoxemia, 2) a conditional recommendation against long-term oxygen use in patients with COPD with moderate chronic resting hypoxemia, 3) conditional recommendations for ambulatory oxygen use in patients with COPD (moderate-quality evidence) or ILD (low-quality evidence) with severe exertional hypoxemia, 4) a conditional recommendation for ambulatory liquidoxygen use in patients who are mobile outside the home and require .3 L/min of continuous-flow oxygen during exertion (very-lowquality evidence), and 5) a recommendation that patients and their caregivers receive education on oxygen equipment and safety (bestpractice statement). Conclusions: These guidelines provide the basis for evidence-based use of home oxygen therapy in adults with COPD or ILD but also highlight the need for additional research to guide clinical practice
