RESUMEN

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.

RESUMEN

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.

RESUMEN

BACKGROUND: Pulmonary fibrosis (PF) is a rare, progressive disease that affects patients and their loved ones on many levels. We sought to better understand the needs and interests of PF patients and their loved ones (collectively "reader-participants") by systematically analyzing their engagement with the World Wide Web (the current version referred to as Web 2.0). METHODS: Data were collected from three PF-focused, interactive websites hosted by physician-investigators with expertise in PF. All data generated by reader-participants for approximately 10 months were downloaded and then analyzed using qualitative content analysis methods. RESULTS: PF experts posted 38 blog entries and reader-participants posted 40 forum entries. Blogs received 363 responses, and forum entries received 108 responses from reader-participants. Reader-participants primarily used the three websites to seek information from or offer a contribution to the PF community. Information was sought about PF symptoms, diagnosis, prognosis, treatments, research, pathophysiology, and disease origin; reader-participants also made requests for new posts and pleas for research and sought clarification on existing content. Contributions included personal narratives about experiences with PF, descriptions of activities or behaviors found to be helpful with PF symptoms, resources or information about PF, and supportive comments to other PF sufferers. CONCLUSIONS: PF patients and their loved ones engage the Web 2.0 environment at these PF-focused sites to satisfy their needs to better understand PF and its impacts and to support others facing similar challenges. Clinicians may find it beneficial to encourage PF patients' involvement in internet forums that foster dynamic, bi-directional information sharing.

RESUMEN

BACKGROUND: Little is known about whether or how supplemental oxygen affects patients with pulmonary fibrosis. METHODS/DESIGN: A mixed-methods study is described. Patients with pulmonary fibrosis, informal caregivers of pulmonary fibrosis patients and practitioners who prescribe supplemental oxygen will be interviewed to gather data on perceptions of how supplemental oxygen impacts patients. In addition, three hundred pulmonary fibrosis patients who do not use daytime supplemental oxygen will be recruited to participate in a longitudinal, pre-/post- study in which patient-reported outcome (PRO) and activity data will be collected at baseline, immediately before daytime supplemental oxygen is initiated, and then once and again 9-12 months later. Activity data will be collected using accelerometers and portable GPS data recorders. The primary outcome is change in dyspnea from before to one month after supplemental oxygen is initiated. Secondary outcomes include scores from PROs to assess cough, fatigue and quality of life as well as the activity data. In exploratory analyses, we will use longitudinal data analytic techniques to assess the trajectories of outcomes over time while controlling for potentially influential variables. DISCUSSION: Throughout the study and at its completion, results will be posted on the website for our research program (the Participation Program for Pulmonary Fibrosis or P3F) at http://www.pulmonaryfibrosisresearch.org.

RESUMEN

RATIONALE: Supplemental oxygen is prescribed to patients with pulmonary fibrosis to normalize oxygen saturations, decrease symptoms and improve quality of life. Along with potential benefits, patients face challenges as they incorporate oxygen into their lives. OBJECTIVE: Our aim was to better understand the perceptions and experiences of patients with pulmonary fibrosis as they confronted the possibility and realities of using supplemental oxygen. METHODS: We performed a mixed-methods study in which we conducted a series of four structured telephone interviews with five patients with pulmonary fibrosis enrolled in a longitudinal observational study. Questionnaires were administered at the time of the interviews, which were conducted at enrollment in the longitudinal study, immediately prior to starting supplemental oxygen, one month and then 9-12 months after starting oxygen. We used conventional content analysis to analyze interview data for themes within and across the four time points. RESULTS: Prior to starting supplemental oxygen, participants uniformly expected it would improve their physical function and quality of life. They also expected practical and psychological limitations, which after starting oxygen, they found to be more pronounced than anticipated. Despite the challenges, participants attributed benefits in symptoms, confidence and mobility to oxygen and came to a reluctant acceptance of it. Their expectations for guidance and support were inadequately met. CONCLUSIONS: For patients with pulmonary fibrosis, starting and using supplemental oxygen on an everyday basis confers benefits while also presenting a significant number of challenges. The process could be improved by providing them with clearer expectations and trustworthy educational resources. Oxygen case managers could help patients incorporate supplemental oxygen more seamlessly into their lives.
