AIM: Older adults at the end-of-life stage receiving home visits from physicians often experience symptoms such as dyspnea, pain and fatigue, among others. This study aimed to investigate the practices and opinions of physicians providing home visits regarding palliative care for older adults with respiratory symptoms due to non-malignant diseases in Japan. METHODS: A nationwide questionnaire survey on home palliative care for non-cancer chronic respiratory diseases was sent to 2988 home-care physicians in 2020 through postal mail and/or email. The questions focused on their background, their use of rating scales to evaluate the intensity of dyspnea, and their practices and opinions regarding home palliative care for respiratory diseases or symptoms. RESULTS: Valid responses were collected from 592 physicians (19.8%). A total of 251 participants (43.1%) used a rating scale to evaluate the intensity of dyspnea. While 87.8%, 86.6%, 67.3%, and 60.0% of physicians considered pulmonary rehabilitation, morphine, sedative medications, and non-invasive positive pressure ventilation (NPPV), respectively, as effective in relieving respiratory distress, 73.0%, 66.9%, 57.3%, and 55.2% of those physicians, respectively, used each modality to relieve respiratory distress. Frequently involved physicians in the aforementioned care prescribed morphine or sedative medications and used NPPV more frequently. CONCLUSIONS: This study found a discrepancy between the proportion of physicians who considered palliative care as effective and those who prescribed it. Geriatr Gerontol Int 2022; 22: 943-949.

BACKGROUND: We developed a novel training program for health care professionals that incorporated shared decision making (SDM) skills training into an advance care planning (ACP) training course, the first in Japan. This study aimed to assess the training program's impact on health care professionals' knowledge, skill, attitudes, and confidence to initiate ACP. METHODS: Using the novel Japanese educational program, we evaluated the effect of 8-month programs conducted eight community training sites of professionals who can practice ACP in a local area in Aichi Prefecture (the Aichi ACP Project). SDM skills training was provided during the workshops conducted in the ACP training course, and the participants' satisfaction and understanding of the training were assessed. After the completion of two workshops, information on SDM skill results from the training and submitted assignments were collected anonymously from the training sites. RESULT: A total of 404 participants completed all education programs. After the first workshop, at least 95% of trainees stated that they were satisfied with the training and that it was useful for ACP practice. The evaluation of the results between the first and second workshops indicated improvement in SDM skills on some items of the SDM measures. In the second workshop, at least 90% of participants submitted implementation reports, and after the second workshop, a survey of confidence in ACP practice was administered, with responses indicating improvement. There were high levels of interest in education related to the ACP practices of oneself and others. CONCLUSIONS: This educational program can be an effective for developing professionals who can practice ACP with SDM skills.

PURPOSE: Severe cardiac dysfunction can manifest with diurnal breathing irregularity. However, it remains to be clarified whether or not diurnal breathing irregularity is observed in patients with heart diseases, including relatively mild chronic heart failure (CHF), compared to those without heart diseases. METHODS: In this cross-sectional study, consecutive inpatients who were admitted for evaluation of sleep-disordered breathing were enrolled. We extracted 3.5 min of stable respiratory signals before sleep onset using polysomnography, analyzed the airflow data using fast Fourier transform, and quantified breathing irregularities using Shannon entropy S. RESULTS: A total of 162 subjects were evaluated. Among these, 39 subjects had heart diseases, including ischemic heart disease (IHD), atrial fibrillation (Af), CHF, and a history of aortic dissection. The values of Shannon entropy S of airflow signals in subjects with heart diseases were significantly higher than in those without heart diseases (p < 0.001). After excluding CHF, the Shannon entropy S was also significantly higher in subjects with heart diseases than in those without heart diseases (p < 0.001). The values of Shannon entropy S were significantly correlated with plasma brain natriuretic peptide levels (r = 0.443, p < 0.001). Although the values were also significantly correlated with body mass index, the presence of heart diseases was independently associated with breathing irregularity in the multiple logistic analysis. Matching analysis revealed consistent differences between subjects with heart diseases and without heart diseases. CONCLUSION: Breathing irregularity was observed before sleep onset in subjects with heart diseases who underwent polysomnography to diagnose sleep-disordered breathing.
