It is considered that olfactory stimulation by fragrance inhalation is one of the methods of relaxation. We examined the possibility by using fragrance inhalation essential oils, such as sweet orange oil and peppermint oil. We measured salivary alpha-amylase activity and state anxiety levels in undergraduate students before and after inhalation. Salivary alpha-amylase activity levels have been utilized to assess the sympathetic nervous activity.
Our results indicate that both salivary alpha-amylase activity and state anxiety levels are significantly reduced after fragrance inhalation of the sweet orange oil. Consequently, our research suggests that sweet orange essential oil has a relaxation effect.

The primary aim of this study was to estimate the number of cancer patients who wanted home death based on the bereaved family survey.A postal survey performed on 1,137 bereaved family members in 4 regions to clarify the degree what they believed that the patient actually died where s/he had wanted on the Good Death Inventory, and to explore the preferred place of death. We calculated estimated number of patients who had wanted home death as a total of (1) the actual number of home death × the percentages of the family members who agreed that the patient actually died where s/he had wanted, and × the actual number of hospital death × the percentages of the family members who disagreed that the patient actually died where s/he had wanted and home was the preferred place of death. Estimated number of cancer patients who wanted home death was 32.8%［95%C.I., 31.7, 33.9］ in the surveyed regions, and 31.2%［95%C.I., 31.1, 31.4］ for national data.

The primary aim of this study was to collect the views of physicians and nurses in the regions where community-based palliative care intervention trial, the OPTIM-study, was performed. A content analysis of free comments of the questionnaire survey was conducted. Questionnaires were mailed to 1,763 physicians and 3,156 nurses after the intervention, and 706 and 2,236 responses were obtained, respectively. A content analysis identified 327 free comments from physicians and 737 from nurses. As favorable effects, the categories [Multidisciplinary teams and community networks were established] [Home-based care is widespread] [Medical knowledge and skills are acquired just as those involved in palliative care] emerged. The main effects of the community palliative care program included the establishment of multidisciplinary teams and community networks, development of home-based care, and increasing knowledge, skills, and awareness about palliative care.

Purpose：To explore a methodology for evaluating end-of-life （EOL） cancer care using diagnosis procedure combination （DPC） administrative data. Methods： We investigated care provided to inpatients whose deaths were attributed to cancer and occurred between August 2010 and December 2012. We measured the quality of palliative care by dividing the decedents into two groups： those who died in the palliative care unit （PCU） and those who died in the general wards（GW）. Results： A total of 311 inpatient deaths were identified as cancer deaths. Of these, 147 patients were included in the PCU group and 164 in the GW group. We calculated the DPC data as follows： the rates of chemotherapy administered within 30 days before death （PCU 0％, GW 27％） and within 14 days before death （PCU 0％, GW 10％）, admission to the intensive care unit （PCU 0％, GW 2％）, life-sustaining interventions （PCU 0％, GW 3％）, rehabilitation sessions （PCU 10％, GW 26％）, emergency admission （PCU 2％, GW 27％）, and antibiotics （PCU 32％, GW 28％）. In the PCU group, rates of chemotherapy and emergency admission were significantly lower（＜0.0001；＜0.0001, respectively）, and rehabilitation sessions were significantly higher （p＝0.0002） than in the GW group. Conclusion： EOL care in a university hospital can be easily investigated using DPC data. Some limitations are the single-site study design, the health insurance system, and secondary use of administrative data. However, this methodology may be adapted to investigate the entire Japanese claim database and to evaluate EOL cancer care.

The purpose of this study was to explore the burden of introducing LCP-J in two wards（medical oncology and respiratory medicine）in Tohoku University Hospital. We administered audit evaluations about dying cancer patients and interviewed 2 doctors and 8 nurses regarding LCP-J intervention. LCP-J was used for 22 patients（38％）, and no significant difference in infusion, potent opioid analgesic and sedative medication within last 48 hours were seen between users and nonusers. Responses were categorized into［confirm directions about dying care among health care professionals］, and［training in dying care in a structured way］as usefulness facets of the LCP-J, and［difficulty in assessment of dying］,［burden of health care professionals］, and［difficulty using LCP-J without knowledge and training in dying care］as burdens of the LCP-J. We explored the burden of LCP-J in general wards, and found that use of the LCP-J could need education in dying care and backup of the palliative care team.

Purpose: To examine the feasibility of the Integrated Palliative care Outcome Scale (IPOS), a comprehensive palliative care scale, for non-cancer patients. Methods: Twenty non-cancer patients and 20 healthcare providers who provide care to the participating patients were asked to complete the IPOS questionnaire, and cognitive interviews were conducted with them. The interviews were analysed using content analysis, a qualitative analysis method. Results: About half to 90% of both patients and healthcare providers answered that they did not find it difficult to answer or understand all items of the IPOS. Therefore, we confirmed its surface validity, and the content validity of the IPOS was confirmed. Conclusion: The surface validity and content validity of the IPOS for non-cancer patients were confirmed, and it became clear that the IPOS can be used as a comprehensive assessment tool for the palliative care of non-cancer patients.

Objective: This study aimed to investigate the feasibility of a patient registry system for assessing PCT (palliative care team) by PRO (Patient-reported outcome) in Japan. Methods: We operated a patient registry system with electronic data collection at eight hospitals in 2021 in Japan. We consecutively included newly referred patients for a month and followed up with them for a month. IPOS or ESAS obtained as PRO at the start of the intervention, three days later, and every week after. The primary endpoint was the response rate to the symptom rating scale by patients and providers. Results: 318 patients were enrolled. The patient response rate was 59.1% at intervention and 37.0% after intervention, and the medical provider response rate was 98.4% at intervention and 70.3% after intervention. Interviews with PCT members indicated that participants required support to input PRO responses required support and paper questionnaire was better and that managing the survey date and overall management was burdensome. Discussion: Although only about half of the patients were able to respond to the PRO, this was the same level as in previous studies. The system and its operation method have many problems. We found that improvements such as reducing items and making the patient interviews paper-based are necessary to expand the system nationwide.
