“…There was insufficient information to determine the risk of allocation bias in the other RCTs. (44,(47)(48)(49)(51)(52)(53) Blinding: two of the fan studies attempted to blind the participants (16,17); a placebo wristband was used as a comparator (16) and participants were not told if the fan to face or fan to leg was the active intervention. (17) There was no blinding in two studies, a cohort and phase II RCT (13,14), and the fifth study stated single blinding that could not be verified from the methods described.…”

Nonpharmacological Interventions for Managing Breathlessness in Patients With Advanced Cancer

et al. 2021

View full text Add to dashboard Cite

IMPORTANCE Breathlessness is a frequent and debilitating symptom in patients with advanced cancer. Often, in the context of breathlessness, aggressive cancer treatment is not beneficial, feasible, or aligned with goals of care. Targeted symptom-focused interventions may be helpful in this scenario.OBJECTIVE To evaluate the advantages and harms of nonpharmacological interventions for managing breathlessness in adults with advanced cancer.EVIDENCE REVIEW PubMed, Embase, CINAHL, Web of Science, and the Cochrane Central Register of Controlled Trials were searched from inception through May 2020 for published randomized clinical trials (RCTs), nonrandomized controlled trials, and observational studies of the advantages and/or harms of nonpharmacological interventions on alleviating breathlessness in adults with advanced cancer. Only English-language studies were screened for eligibility, titles, abstracts, and full text. Risk of bias and strength of evidence (SOE) were independently assessed. The key outcomes reported in studies were breathlessness, anxiety, exercise capacity, health-related quality of life, and harms. Data were analyzed from October 1, 2019, to June 30, 2020.FINDINGS A total of 29 RCTs (2423 participants) were included. These RCTs evaluated various types of interventions, such as respiratory (9 RCTs), activity and rehabilitation (7 RCTs), behavioral and psychoeducational (3 RCTs), integrative medicine (4 RCTs), and multicomponent (6 RCTs). Several nonpharmacological interventions were associated with improved breathlessness, including fan therapy (standardized mean difference [SMD], −2.09; 95% CI, −3.81 to −0.37; I 2 = 94.3%; P for heterogeneity = .02; moderate SOE) and bilevel ventilation (estimated slope difference, −0.58; 95% CI, −0.92 to −0.23; low SOE), lasting for a few minutes to hours, in the inpatient setting. In the outpatient setting, nonpharmacological interventions associated with improved breathlessness were acupressure and reflexology (integrative medicine) (low SOE) and multicomponent interventions (combined activity and rehabilitation, behavioral and psychoeducational, and integrative medicine) (low SOE) lasting for a few weeks to months. Five of the 29 RCTs (17%) reported adverse events, although adverse events and study dropouts were uncommon.CONCLUSIONS AND RELEVANCE Findings of this review include the safety and association with improved breathlessness of several nonpharmacological interventions for adults with advanced cancer. Guidelines and clinical practice should evolve to incorporate nonpharmacological interventions as first-line treatment for adults with advanced cancer and breathlessness.

AimTo explore nurses' perceptions to alleviate dyspnoea in inpatients with advanced cancer while receiving palliative care.DesignA descriptive qualitative design.MethodsSeven focus groups were conducted with nurses (n = 27) from five specialized palliative care wards in four hospitals in south and southwest Finland. The focus groups were conducted between June and November 2019, and the transcripts were analysed using inductive analysis.ResultsThe findings revealed three categories: recognizing dyspnoea is a multi‐faceted problem, dealing with the complexity of assessment of dyspnoea and strategies for relieving dyspnoea. Nurses perceived the complexity of dyspnoea as a symptom and emphasized the importance of utilizing patients' subjective experiences and consistent assessment scales to determine its severity. Furthermore, nonpharmacological interventions are as pertinent as pharmacological and medical interventions. The findings can assist nurses in selecting appropriate interventions for dyspnoea care, ultimately enhancing the quality of patient care and patient safety.

The Effect of Using an Electric Fan on Dyspnea in Chinese Patients With Terminal Cancer

Abstract: The results of the study suggested that fan therapy could be effective in alleviating dyspnea in Chinese patients with advanced cancer. It should be considered as one of the nonpharmacological treatment option. Future large-scale phase 3 clinical trials are warranted.
