Context: Episodic breathlessness is characterized by increased breathlessness intensity, and it is burdensome for patients. A vicious cycle of breathlessness-anxiety/panic-breathlessness leads to emergencies that can rarely be alleviated by drugs. Non-pharmacological interventions seem to be beneficial: Can a brief cognitive and behavioral intervention help patients to better manage episodic breathlessness?Objectives: To evaluate the feasibility, safety, acceptability, and potential effects of a brief cognitive and behavioral intervention for the management of episodic breathlessness.Methods: Between February 2019 and February 2020, 49 patients with life-limiting diseases suffering from episodic breathlessness were enrolled in the single-arm phase II study. The baseline assessment was followed by the one- to two-hour intervention. In weeks two, four, and six after the intervention, the outcomes (main outcome of potential effects: mastery of breathlessness) were assessed, and in week six, a qualitative interview, and the final assessment took place. A mixed-methods approach was used to evaluate mainly the feasibility, including interviewing informal carers.Results: 46/49 patients (24 female; 36 with COPD; mean age: 66.0 years) participated in the baseline assessment, 38 attended the intervention, 32 completed the final assessment, and 22 were interviewed. Study procedures and the intervention were feasible and mainly well accepted and patients did not experience burdens caused by it (28/32). In the interviews, patients described a positive change in their competencies in managing episodic breathlessness and feelings of anxiety during the episode. Mastery of breathlessness improved after the intervention.Conclusion: The brief cognitive and behavioral intervention and the study procedures are feasible, safe, and well accepted. We can describe a change for better management of episodic breathlessness in patients after the intervention, still, this needs to be evaluated in a Phase III trial for inclusion in the management of episodic breathlessness.

Context: Episodic breathlessness is a distressing and difficult to treat symptom because of its short duration. Fast actioned intranasal fentanyl (INF) is potentially more suitable than oral opioids.Objectives: To examine the feasibility, preliminary efficacy, and safety of INF for the treatment of episodic breathlessness from advanced nonmalignant conditions in hospice patients.Methods: Phase IIB, double-blind, randomized controlled, multisite, INF citrate solution vs. placebo crossover feasibility study. Opioid-tolerant patients were to treat six episodes of breathlessness using INF spray. The primary outcome was change in the Visual Analogue Scale for dyspnea (VAS-D) score from baseline to 15 minutes after study drug's administration (VAS-D15). Other outcomes were to collect demographic data and determine the use of rescue medications, safety, and feasibility of the study design.Results: Twenty-one of 49 eligible patients were enrolled, and 19 (90%) patients completed the study. The mean difference in VAS-D15 between fentanyl and placebo was -3.37 mm (95% CI = -10.35 to 3.61 mm; P = 0.337). There was no statistically significant or clinically meaningful difference between INF and placebo in relieving the sensation of discomfort in episodic breathlessness. No significant drug-related adverse event or detrimental effect on vital signs was observed.Conclusion: We found no difference between INF and placebo in relieving episodic breathlessness in nonmalignant conditions. INF was well tolerated, and the study design proved to be feasible in hospice patients with advanced diseases. Future study using higher concentration of fentanyl solution may be warranted.

Background: Episodic breathlessness is often accompanied by panic. A vicious cycle of breathlessness-panic-breathlessness leads to emergencies with severe breathlessness and/or fear of dying. However, the interaction between episodic breathlessness and panic is poorly understood. Thus, the aim is a better understanding of the interaction between panic and episodic breathlessness to develop appropriate support for patients suffering from this symptom., Methods: Patients suffering from episodic breathlessness due to life-limiting diseases answered questions on the characteristics of episodic breathlessness and panic-spectrum psychopathology, including underlying mechanisms. Using the Patient Health Questionnaire and the Structured Clinical Interview for DSM-IV Diagnoses (SCID), patients were screened for panic disorder. An open-ended question captured the patients' descriptions of panic during breathlessness episodes., Results: Forty-six patients [52% women, mean age =66 years; standard deviation (SD) 7.3 years] provided information: 61% suffered from panic during the entire breathlessness episode, 39% experienced panic in every episode, and 25% were diagnosed with panic disorder. Exploratory data analysis was conducted. Patients with high scores in breathlessness catastrophizing thoughts experienced more panic in a breathlessness episode (P<0.001) and considered themselves more panic than low-scorers (P=0.024). There was a significant indirect effect of episodic breathlessness intensity on the panic experienced in an episode, and this effect was mediated by catastrophizing thoughts regarding breathlessness (b=0.164; 95% CI: 0.105, 0.222). Patients described in the open-ended question experiencing only panic or breathlessness, or a combination of both. Some patients managed to differentiate panic from episodic breathlessness, and used strategies to avoid panic in an episode., Conclusions: Research on treatment options for episodic breathlessness should not only focus on panic in breathlessness episodes, but also on underlying mechanisms such as catastrophizing thoughts, as they aggravate the burden.

Purpose Breathlessness is a distressing symptom, particularly common in those with advanced lung cancer. Previous research has identified the symptom occurrence of episodic breathlessness, identifying average frequency, duration and severity of episodes, but has not explored the distress specifically associated with these episodes. This study explored the distress associated with episodic breathlessness for adults with advanced cancer and the relative impact of three elements; frequency, duration or severity. Methods Semi-structured interviews were conducted with four participants with advanced lung cancer. Analysis adopted an interpretative phenomenological approach. Results A complex relationship existed between distress caused by episodic breathlessness and its frequency, duration and severity for study participants. Episodic breathlessness had a significant impact on participant's perceptions of self and previous experience effected how distressed they were by their breathlessness. The emotional work created by the symptom was considerable for individuals. Conclusion The study highlights the importance of recognizing symptoms as a combination of different experiences that may each cause different levels of distress. Initial evidence is provided that the emotional work involved for patients to self-manage each separate element of breathlessness should be considered in its treatment. [ABSTRACT FROM AUTHOR]

Purpose: The internationally consented definition and categorization describe two categories of episodic breathlessness: predictable (with known triggers) and unpredictable. The link of known triggers only to predictable episodes can be read that unpredictable episodes have none known trigger. Our aim was to illuminate patients' experiences with episodes of unpredictable breathlessness, to collect descriptions of the episodes' impact on the patients' lives, and, in turn, the patients' individual coping strategies in this connection.Design: Qualitative study using semi-structured in-depth interviews with patients suffering from unpredictable episodes of breathlessness and chronic obstructive pulmonary disease (COPD; Global Initiative for Obstructive Lung Disease III and IV) or lung cancer (all stages). Interviews were audio-recorded, transcribed verbatim, and analyzed using Framework Analysis.Results: One hundred one patients were screened in a large university hospital; ten participants fulfilled the inclusion criteria and provided consent. The experienced episodes were evaluated as unpleasant and with higher intensity compared to predictable episodes. Non-pharmacological interventions were identified as useful coping strategies. Interestingly, although patients experienced the episodes in an unpredictable manner, a trigger could be detected retrospectively for the majority of cases (mostly emotions (especially panic) and, occasionally, physical exertion). Unpredictable episodes are less frequent than previously assumed.Conclusion: The unpredictability of unpredictable breathless episodes refers to the patients' experience that these episodes occur "out-of-the-blue." However, a known trigger can be identified for the majority of unpredictable breathless episodes. These are therefore triggered as well. Further research needs to describe more possible triggers, to inquire the prevalence of unpredictable episodic breathlessness, and to develop effective management strategies. [ABSTRACT FROM AUTHOR]

Background: The aim of this study was to assess the phenomenon of episodic breathlessness in advanced cancer patients followed by palliative care services at home.Methods: A consecutive sample of patients with advanced cancer, admitted to home care for a period of six months, was surveyed. The presence of background breathlessness and episodic breathlessness, their intensity, and drugs used for their treatment were collected. Factors inducing episodic breathlessness, and its influence on daily activities were investigated.Results: Three hundred forty-seven advanced cancer patients admitted to home palliative care were surveyed. The prevalence of breathlessness was 35.3%. The mean intensity of breathlessness was 3.8 (SD 1.96), out of a maximum score of 10 for worst imaginable. Sixty patients (49.2%) were receiving drugs for background breathlessness. In the multivariate analysis the risk of breathlessness increased with cardiovascular disease, chronic obstructive pulmonary disease, and lung cancer while it decreased in patients with a better performance status. The prevalence of episodic breathlessness in patients with background breathlessness was 79.5% and its mean intensity was 7.1 (SD 1.5, range 2-10). The mean duration of episodic breathlessness was 28.6 minutes (SD 47.1, range 1-300 minutes). Forty-three patients (44.3%) were receiving one or more drugs as needed. The majority of episodic breathlessness events were triggered by activity. Episodic breathlessness was interfering with daily activities in 65 patients (67%). Episodic breathlessness wasn't associated with any variable taken into consideration.Conclusion: This study showed that episodic breathlessness frequently occurs in advanced cancer patients admitted to home care, is severe in intensity, is triggered in most cases by activity, and is characterized by a short duration which requires rapid measures.

Context Episodic breathlessness is a frequent and burdensome symptom in cancer patients but pharmacological treatment is limited. Objectives To determine time to onset, efficacy, feasibility, and safety of transmucosal fentanyl in comparison to immediate-release morphine for the relief of episodic breathlessness. Methods Phase II, investigator-initiated, multicenter, open-label, randomized, morphine-controlled, crossover trial with open-label titration of fentanyl buccal tablet (FBT) in inpatients with incurable cancer. The primary outcome was time to onset of meaningful breathlessness relief. Secondary outcomes were efficacy (breathlessness intensity difference at 10 and 30 minutes; sum of breathlessness intensity difference at 15 and 60 minutes), feasibility, and safety. Study was approved by local ethics committees. Results Twenty-five of 1341 patients were eligible, 10 patients agreed to participate (four female, mean age 58 ± 11, mean Karnofsky score 67 ± 11). Two patients died before final visits and two patients dropped-out because of disease progression leaving six patients for analysis with 61 episodes of breathlessness. Mean time to onset was for FBT 12.7 ± 10.0 and for immediate-release morphine 23.6 ± 15.1 minutes with a mean difference of −10.9 minutes (95% CI = −24.5 to 2.7, P = 0.094). Efficacy measures were predominately in favor for FBT. Both interventions were safe. Feasibility failed because of too much study demands for a very ill patient group. Conclusion The description of a faster and greater relief of episodic breathlessness by transmucosal fentanyl versus morphine justifies further evaluation by a full-powered trial.

Context: Episodic breathlessness causes additional distress to breathless patients with advanced disease, but management is still insufficient and there is a lack of knowledge on effective coping strategies.Objectives: The aim was to explore patients' self-management strategies for episodic breathlessness.Methods: In-depth interviews with patients suffering from episodic breathlessness as a result of chronic heart failure, chronic obstructive pulmonary disease, lung cancer, or motor neuron disease were conducted. Interviews were transcribed verbatim and analyzed guided by the analytic hierarchy of Framework analysis.Results: A total of 51 participants were interviewed (15 chronic heart failure, 14 chronic obstructive pulmonary disease, 13 lung cancer, and nine motor neuron disease; age, mean [SD], 68 [12], 41% women, median Karnofsky index 60%). They described six main strategies for coping with episodes of breathlessness: reduction of physical exertion, cognitive and psychological strategies, breathing techniques and positions, air and oxygen, drugs and medical devices, and environmental and other strategies. Some strategies were used in an opposing way, e.g., concentrating on the breathing vs. distraction from any thoughts of breathlessness or laying down flat vs. standing up and raising hands.Conclusion: Patients used a number of different strategies to cope with episodic breathlessness, adding more detailed understanding of existing strategies for breathlessness. The findings, therefore, may provide a valuable aid for health care providers, affected patients, and their relatives. [ABSTRACT FROM AUTHOR]

Context: Episodic breathlessness is a relevant aspect in patients with advanced cancer.Objectives: The aim of this study was to assess the different aspects of this clinical phenomenon.Methods: A consecutive sample of patients with advanced cancer admitted to different settings for a period of six months was surveyed. The presence of background breathlessness and episodic breathlessness, their intensity (numerical scale 0-10), and drugs used for treatment were collected. Factors inducing episodic breathlessness and its influence on daily activities were investigated.Results: Of 921 patients, 29.3% (n = 269) had breathlessness and 134 patients (49.8%) were receiving drugs for background breathlessness. In the multivariate analysis, the risk of breathlessness increased with chronic obstructive pulmonary disease, although it decreased in patients receiving disease-oriented therapy and patients with gastrointestinal tumors. The prevalence of episodic breathlessness was 70.9% (n = 188), and its mean intensity was 7.1 (SD 1.6). The mean duration of untreated episodic breathlessness was 19.9 minutes (SD 35.3); 41% of these patients were receiving drugs for episodic breathlessness. The majority of episodic breathlessness events (88.2%) were triggered by activity. In the multivariate analysis, higher Karnofsky Performance Status levels were significantly related to episodic breathlessness, although patients receiving disease-oriented therapy were less likely to have episodic breathlessness.Conclusion: This study showed that episodic breathlessness frequently occurs in patients with breathlessness in the advanced stage of disease, has a severe intensity, and is characterized by rapid onset and short duration, which require rapid measures.

The article focuses on a study which aims to describe the characteristics of episodic breathlessness in patients with advanced chronic obstructive pulmonary disease or lung cancer. It says that episodic breathlessness is a form of refractory breathlessness and that better understanding of the symptom is necessary for effective management. It concludes that effective management strategies are guaranteed to improve symptom relief and coping.

Abstract: Context: Episodic breathlessness is a common and distressing symptom in patients with advanced disease. Still, it is not yet clearly defined. Objectives: The aim of this work was to develop an international definition, categorization, and terminology of episodic breathlessness. Methods: An online Delphi survey was conducted with international breathlessness experts. We used a structured questionnaire to identify specific aspects and reach agreement on a definition, categorization, and terminology (five-point Likert scale). Consensus was defined in advance as ≥70% agreement. Results: Thirty-one of 68 (45.6%), 29 of 67 (43.3%), and 33 of 67 (49.3%) experts responded in the first, second, and third rounds, respectively. Participants were 20–79 years old, about 60% male, and more than 75% rated their own breathlessness expertise as moderate to high. After three rounds, consensus was reached on a definition, categorization, and terminology (84.4%, 96.3%, and 92.9% agreement). The final definition includes general and qualitative aspects of the symptom, for example, time-limited severe worsening of intensity or unpleasantness of breathlessness in the patient's perception. Categories are predictable or unpredictable, depending on whether any triggers can be identified. Conclusion: There is high agreement on clinical and operational aspects of episodic breathlessness in advanced disease among international experts. The consented definition and categorization may serve as a catalyst for clinical and basic research to improve symptom control and patients' quality of life. [Copyright &y& Elsevier]

Background: Episodic breathlessness is a common form of chronic breathlessness that is highly distressing for patients with diseases such as chronic obstructive pulmonary disease (COPD) and lung cancer in advanced stages. Little is known about the experiences of informal caregivers who care for patients with episodic breathlessness. The present study aims to explore and describe the experiences and coping strategies of informal caregivers who deal with this challenging condition., Methods: This is a qualitative study based on semi-structured in-depth interviews with informal caregivers of patients suffering from episodic breathlessness. The interviews were recorded, transcribed verbatim, and analyzed using Mayring's qualitative content analysis., Results: Thirteen informal caregivers were interviewed. The results suggest that the distress patients often experience during episodic breathlessness causes concern and anxiety among most informal caregivers. Particularly stressful for them is their own helplessness and uncertainty, especially when episodic breathlessness occurs for the first time. Over time, all informal caregivers interviewed had developed strategies to cope with the patients' episodic breathlessness. These strategies can be divided into two categories: (I) strategies directed at the patient to provide appropriate support during episodic breathlessness, and (II) strategies aimed at coping with the caregiver's own emotional burden. Despite these strategies, the need for professional support for informal caregivers often remains unmet, especially during the initial onset of episodic breathlessness., Conclusions: Informal caregivers of patients with chronic breathlessness need support and advice on how to better cope with episodic breathlessness. Both patient and caregiver support need to be part of a comprehensive approach, e.g., as part of a breathlessness service.

Context: Episodic breathlessness is characterized by a severe worsening of breathlessness intensity that goes beyond usual fluctuations. Episodes are usually short; therefore, nonpharmacological strategies (cognitive and behavioral) seem most promising to be beneficial. Which strategies-delivered separately or in combination-might be most effective and feasible remains unclear.Objectives: The Delphi survey selects and determines different nonpharmacological strategies for coping with episodic breathlessness to develop a brief cognitive and behavioral intervention for the management of episodic breathlessness.Methods: Using an online Delphi survey comprising three rounds, international, multidisciplinary experts in breathlessness summarized and determined cognitive and behavioral strategies. The a priori target agreement for close-ended questions was 70%.Results: Experts (n = 41/87; n = 45/85; n = 36/85) agreed on 15 of the 31 cognitive and behavioral strategies. Based on the panellists' opinion, the final version of the cognitive and behavioral intervention comprised the following characteristics: individually tailored intervention, a high proportion of communication, short duration, the involvement of carers, and use of the Breathing, Thinking, Functioning Model of Spathis et al. Consensus upon the delivery of the subsequent strategies within the intervention was reached: handheld fan, forward lean, diaphragmatic breathing, distraction, pursed lips breathing, long breaths out, and relaxation training.Conclusion: Using the consented nonpharmacological strategies, a brief cognitive and behavioral intervention was developed that balances between individualization and standardization of the intervention.

Aim: To characterize episodic breathlessness (EB) in patients with advanced cancer, and to determine factors influencing its clinical appearance. Methods: A consecutive sample of advanced cancer patients admitted to an acute palliative care unit was surveyed. Continuous dyspnea and EB were measured by a numerical scale. The use of drugs used for continuous dyspnea and EB was recorded. Patients were asked about the characteristics of EB (frequency, intensity, duration and triggers). The Multidimensional dyspnea profile (MDP), the Brief dyspnea inventory (BDI), the Athens sleep scale (AIS) and the Hospital Anxiety and Depression Scale (HADS) were also administered. Results: From 439 advanced cancer patients surveyed, 34 and 27 patients had EB, without and with background dyspnea, respectively. The mean intensity and the number of episodes were higher in patients with background dyspnea (p < 0.0005 and p = 0.05, respectively). No differences in duration were observed. Most episodes lasted <10 min. A recognizable cause triggering EB was often found. The presence of both background dyspnea and EB was associated with higher values of MDP and BDI. EB was independently associated with frequency and intensity of background dyspnea (OR = 20.9, 95% CI (Confidence interval) 9.1–48.0; p < 0.0005 and OR = 1.97, 95% CI 1.09–3.58; p = 0.025, respectively) and a lower Karnofsky level (OR = 0.96, 95%CI 0.92–0.98, p = 0.05). Discussion: EB may occur in patients with and without continuous dyspnea, and is often induced by physical and psychological factors. EB intensity is higher in patients with continuous dyspnea. The duration was often so short that the use of drugs, as needed, may be too late, unless administered pre-emptively when the trigger was predictable. [ABSTRACT FROM AUTHOR]
