  • Age Group Differences in Daily Life Changes among Community Residents during the COVID-19 Pandemic: A Pilot Study on Intergenerational Comparison

    Natsuki Yamamoto-takiguchi, Eiko Uchiyama, Hiroki Fukahori, Atsuko Taguchi, Satoko Nagata

    The Keio Journal of Medicine (Keio Journal of Medicine)  72 ( 1 ) 11 - 20 2023.01

    Lead author, Accepted,  ISSN  0022-9717

     View Summary

    This study investigated lifestyle changes and the self-reported mental health status of Japanese community residents during the COVID-19 pandemic. Differences in demography, daily lifestyle changes, and approaches to problem solving were analyzed in two age cohorts (<60 vs ≥60 years). The prevalence of moderate/increased psychological distress was 31.7%, with no significant difference between the cohorts. Compared with the pre-COVID-19 era, more than 80% of the participants stopped eating out and spent more time at home, and more than 70% used public transport less frequently. There were significant differences between the cohorts for the time spent at home, opportunities to eat meals outside of home, and shopping in stores. Participants aged under 60 years were less likely to use television and newspapers or to consult a family doctor. Those aged over 60 years were less likely to consult friends/colleagues or to use the Internet/social networking services. Identifying the risk factors for psychological distress is warranted for implementing measures to maintain and improve the physical and mental health of residents.

  • Characteristics of Patient Safety Incident Occurrences Reported by Japanese Homecare Nurses: A Prospective Observational Study

    Natsuki Yamamoto-Takiguchi, Takashi Naruse, Mahiro Fujisaki-Sueda-Sakai, Noriko Yamamoto-Mitani

    Nursing Reports (MDPI AG)  11 ( 4 ) 997 - 1005 2021.12

    Research paper (scientific journal), Joint Work,  ISSN  2039439X

     View Summary

    Patient safety incidents (PSIs) prevention is important in healthcare because PSIs affect patients negatively and increase medical costs and resource use. However, PSI knowledge in homecare is limited. To analyze patient safety issues and strategies, we aimed to identify the characteristics and contexts of PSI occurrences in homecare settings. A prospective observational study was conducted between July and November 2017 at 27 Japanese homecare nurse (HCN) agencies. HCNs at each agency voluntarily completed PSI reports indicating whether they contributed to PSIs or were informed of a PSI by the client/informal caregiver/other care provider during a period of three months. A total of 139 PSIs were analyzed, with the most common being falls (43.9%), followed by medication errors (25.2%). Among the PSIs reported to the HCN agencies, 44 were recorded on formal incident report forms, whereas 95 were reported as PSIs that required a response (e.g., injury care) but were not recorded on formal incident report forms. Most PSIs that occurred when no HCN was visiting were not recorded as incident reports (82.1%). Developing a framework/system that can accumulate, analyze, and share information on PSIs that occur in the absence of HCNs may provide insights into PSIs experienced by HCN clients.

  • Home safety practices to prevent child injury and its association with family and children's daily routines in Japan: A cross-sectional study

     View Summary

    © 2019 Japan Academy of Nursing Science Aim: To investigate the association between children and their families' daily life routines and the implementation of safety practices in their homes. Methods: A cross-sectional study was conducted using a self-administered questionnaire among parents of 3-year-old children, who visited a public health center in Tokyo for their health checkups. Associations between the implementation of safety practices and family and children's basic daily routines were assessed using a multivariate logistic regression. Results: Data from 336 parents were analyzed. Three items were found to be significantly related to the non-implementation of safety practices, such as “television-watching behavior: after 8:00 p.m.” (adjusted odds ratio = 1.88, p =.02), “washing hands: not every time after getting home” (adjusted odds ratio = 2.24, p =.02), and “Family Routines Inventory: lower score” (a measurement of the routinization of a family's daily life; adjusted odds ratio =.83, p =.01). Conclusion: The cumulative results suggest that the lack of safety practices implementation signify nonadherence to daily routine practices by parents.

  • Relationship between maternal mindfulness and anxiety 1 month after childbirth

    Yamamoto, Natsuki, Naruse, Takashi, Sakai, Mahiro, Nagata, Satoko

    JAPAN JOURNAL OF NURSING SCIENCE 14 ( 4 ) 267 - 276 2017.10

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  1742-7932

     View Summary

    AIM: To investigate the relationship between maternal mindfulness and maternal anxiety 1 month after childbirth. METHODS: A cross-sectional design was used, featuring anonymous questionnaires that were completed between July and December 2014 at two Japanese hospitals. The participants (n = 151) completed the Mindful Attention Awareness Scale (Japanese version) and the State-Trait Anxiety Inventory Form X (Japanese version). The data analysis was carried out by using a hierarchical multiple regression. RESULTS: The state and trait anxiety scores showed significant relationships with mindfulness, the mother's age, and the perceived difference between the expectations of motherhood before childbirth and the reality of post-partum daily life. Furthermore, the amount of average sleep time in the past week (including naps) showed a negative association with the state anxiety score, whereas the marital relationship showed a positive association with trait anxiety. Finally, at 1 month post-partum, the mothers with greater mindfulness scores showed lower anxiety. CONCLUSIONS: Improvements in mindfulness could help mothers to reduce their post-partum anxiety.

     View Summary

    (1) From the interviews after the trial of the prototype system, there were opinions that the system can be accessed from any location and that the reports are easy to make because the items are mainly selective. On the other hand, some respondents requested that the quality of the descriptive part of the case summary (descriptive type) be assured to a certain extent in order to grasp the details of the accident.
    (2) There was a tendency for homecare agencies (HCAs) with higher psychological safety of staff to regularly post-incident reviews were conducted (p=0.057).
    On the other hand, 20.5% of the HCAs regularly conduct post-incident review, and the highest proxy learning need of the homecare nurses was "recurrence prevention measures reviewed after an accident or other incident" (78.2%).
