    英語, 研究論文(学術雑誌), BACKGROUND: Palliative care phase is a tool to assess five phases that reflect a patient's care needs: stable, unstable, deteriorating, terminal, and bereavement. The palliative care phase is routinely used to describe the clinical status of patients and their families. Australia has established nationwide benchmarks for comparing care services. However, the reliability of palliative care in Japan has not yet been verified. This study aimed to develop a Japanese version of the palliative care phase and examine its inter-rater reliability. METHODS: This was a multicenter, cross-sectional study. Based on previous studies, two healthcare providers evaluated the single-patient phase and calculated kappa coefficients. The reliability was assessed between March 2024 and November 2024 in a palliative care facility in Japan. RESULTS: A total of 419 phase evaluations were conducted. The inter-rater reliability was a kappa of 0.47 (95% confidence interval 0.40-0.54). Assessment disagreements were most common during the unstable and deteriorating phases (11.7%). There were no statistically significant differences in the matches or mismatches in the assessment of the adequacy of the phases (P = 0.338). CONCLUSION: The Japanese version of the palliative care phase was well-adapted for use in clinical palliative care. However, the concepts underlying these phases are not clearly distinguishable. In the future, we need to further educate healthcare providers and accumulate experience through on-the-job training to improve the quality of care through palliative care outcome measurements and benchmarking during the palliative care phase.

    英語, 研究論文(学術雑誌), BACKGROUND: Although the relationship between medication status, symptomatology, and outcomes has been evaluated, data on the prevalence of polypharmacy and potentially inappropriate medications (PIMs) and the association of polypharmacy and PIMs with swallowing function during follow-up are limited among hospitalized patients aged ≥65 years with dysphagia. METHODS: In this 19-center cohort study, we registered 467 inpatients aged ≥65 years and evaluated those with the Food Intake LEVEL Scale (FILS) scores ≤8 between November 2019 and March 2021. Polypharmacy was defined as prescribing ≥5 medications and PIMs were identified based on the 2023 Updated Beers criteria®. We applied a generalized linear regression model to examine the association of polypharmacy and PIMs with FILS score at discharge. RESULTS: We analyzed 399 participants (median age, 83.0 years; males, 49.8%). The median follow-up was 51.0 days interquartile range, 22.0-84.0 days]. Polypharmacy and PIMs were present in 67.7% of and 56.1% of patients, respectively. After adjusting for covariates, neither polypharmacy (β = 0.05 [95% confidence interval (CI), -0.04-0.13], p = 0.30) nor non-steroidal anti-inflammatory medications (β = 0.09 [95%CI, -0.02-0.19], p = 0.10) were significantly associated with FILS score at discharge. CONCLUSIONS: The results of this study indicated a high proportion of polypharmacy and PIMs among inpatients aged ≥65 years with dysphagia. Although these prescribed conditions were not significantly associated with swallowing function at discharge, our findings suggest the importance of regularly reviewing medications to ensure the appropriateness of prescriptions when managing older inpatients.

    英語, 研究論文(学術雑誌), OBJECTIVES: To clarify the relationship between Phase of Illness at the time of admission to palliative care units and symptoms of patients with advanced cancer. METHODS: This study was a secondary analysis of the East Asian collaborative cross-cultural Study to Elucidate the Dying process. Palliative physicians recorded data, including Phase of Illness, physical function and the Integrated Palliative care Outcome Scale. We used multinomial logistic regression to analyse ORs for factors associated with Phase of Illness. Twenty-three palliative care units in Japan participated from January 2017 to September 2018. RESULTS: In total, 1894 patients were analysed-50.9% were male, mean age was 72.4 (SD±12.3) years, and Phase of Illness at the time of admission to the palliative care unit comprised 177 (8.9%) stable, 579 (29.2%) unstable, 921 (46.4%) deteriorating and 217 (10.9%) terminal phases. Symptoms were most distressing in the terminal phase for all items, followed by deteriorating, unstable and stable (p<0.001). The stable phase had lower association with shortness of breath (OR 0.73, 95% CI 0.57 to 0.94) and felt at peace (OR 0.73, 95% CI 0.56 to 0.90) than the unstable phase. In the deteriorating phase, weakness or lack of energy (OR 1.20, 95% CI 1.02 to 1.40) were higher, while drowsiness (OR 0.82, 95% CI 0.71 to 0.97) and felt at peace (OR 0.81, 95% CI 0.71 to 0.94) were significantly lower. CONCLUSION: Our study is reflective of the situation in palliative care units in Japan. Future studies should consider the differences in patients' medical conditions and routinely investigate patients' Phase of Illness and symptoms. TRIAL REGISTRARION NUMBER: UMIN000025457.

    英語, 研究論文(学術雑誌), The accuracy of body mass index (BMI) for sarcopenic dysphagia diagnosis, which remains unknown, was evaluated in this study among patients with dysphagia. We conducted a 19-site cross-sectional study. We registered 467 dysphagic patients aged ≥ 20 years. Sarcopenic dysphagia was assessed using a reliable and validated diagnostic algorithm. BMI was assessed using the area under the curve (AUC) in the receiver operating characteristic analysis to determine diagnostic accuracy for sarcopenic dysphagia. The study included 460 patients (median age, 83.0 years (76.0-88.0); men, 49.8%). The median BMI was 19.9 (17.3-22.6) kg/m2. Two hundred eighty-four (61.7%) patients had sarcopenic dysphagia. The AUC for sarcopenic dysphagia was 0.60-0.62 in the overall patients, male, female, and patients aged ≥ 65 years The BMI cut-off value for sarcopenic dysphagia diagnosis was 20.1 kg/m2 in the overall patients (sensitivity, 58.1%; specificity, 60.2%) and patients aged ≥ 65 years (sensitivity, 59.8%; specificity, 61.8%). Conclusion: Although the AUC, sensitivity and specificity of BMI for sarcopenic dysphagia diagnosis was approximately 0.6, BMI < 20.0 kg/m2 might be a predictor for sarcopenic dysphagia. In clinical settings, if patients with dysphagia have a BMI < 20.0 kg/m2, then sarcopenic dysphagia should be suspected as early as possible after admission.

    Annals of palliative medicine, 2022年09月30日, [査読有り], [筆頭著者], [国際誌]
    英語, 研究論文(学術雑誌), BACKGROUND: People receiving palliative care have complex, wide-ranging, and changing needs, not just physical distress, but also psychosocial, practical, and spiritual. Influences on complexity in palliative care are different among healthcare providers and may depend on diverse aspects of the patient's condition, time, and environment. Therefore, this study aimed to integrate and describe the perspective of complexity in palliative care. METHODS: We used an integrative review, which is a method of compiling, summarizing, and analyzing existing insights from previous studies. We conducted an electronic literature search in MEDLINE (Ovid), PsycINFO (EBSCOhost), Web of Science Core Collection, and CINAHL (EBSCOhost), examining literature from May 1972 to September 2020 and updated in December 2020. Subsequently, synthesis without meta-analysis of the findings was completed. RESULTS: We identified 32 peer-reviewed articles published in English. The included literature mainly originated in Europe and the United States. The research methods included quantitative studies (n=13), qualitative studies (n=12), case studies (n=3), and reviews (n=4). We identified 29 that influenced complexity in palliative care, 25 perceptions of the patient, including background and physical, psychological, social, and spiritual; two perceptions in the healthcare setting; and two perceptions in the socio-cultural setting. Above all, the perceptions of complexity in palliative care included younger age, prognosis, and spirituality. In addition, we added the identified perceptions of complexity with references to the complexity model in palliative care. DISCUSSION: Although this review was limited in its search strategy and some data sources may have been overlooked, it still provided perceptions that influenced complexity in palliative care. These complex influencing perceptions are necessary for patients to receive appropriate palliative care at the right time and for health care providers to conduct a multi-disciplinary team approach. Furthermore, longitudinal prospective data are needed to examine the changes and relationships among complexity over time.

    本研究は、緩和ケアの必要性を評価するための尺度である「Phase of Illness」の信頼性と妥当性を検証し、緩和ケアの経過を俯瞰するディスカッションマップを作成することを目標としている。この尺度は、緩和ケアの適切な時期の判断や、緩和ケアの介入のアウトカムとして有効であるかどうかを明らかにすることも可能であると考えられている。
    初年度にあたる2023年度は、Phase of Illnessに関する文献レビューを実施し、海外でのPhase of Illnessの研究状況や活用の方法を集約し、日本における実用性を評価した。その結果、「Phase of Illness」はがん患者だけでなく非がん患者にも適用可能であり、医療提供体制や職種を問わず、医療者が容易に評価できることが明らかになった。さらに、「Phase of Illness」は、患者の病状の変化に応じて柔軟に対応できるため、緩和ケアの質を向上させるための有効なツールであると考えられた。これらのことから、Phase of Illnessの評価一致性による信頼性と症状評価による概念妥当性を検証するため、新たな調査項目をエキスパートパネルで検討を行った。対象施設は、緩和ケア病棟および在宅緩和ケア施設を含む複数の医療機関で、データ収集と分析を進めている。この調査により、Phase of Illnessが実際の臨床現場でどのように活用されているか、また、その活用が緩和ケアの質にどのような影響を与えているかを評価することができる。
