  • Factors Influencing Psychological Safety Among Japanese Home Care Nurses

    Natsuki Yamamoto-Takiguchi, Satoko Nagata

    Home Health Care Management & Practice (SAGE Publications)   2025.05

    Lead author, Corresponding author, Accepted,  ISSN  1084-8223

    　View Summary

    Aim:

    This study aimed to identify factors related to the psychological safety of Japanese home care nurses (HCNs).

    Methods:

    This cross-sectional study recruited Japanese HCNs. The HCNs completed a questionnaire based on the Japanese version of the Psychological Safety Scale at their home care nursing agency (HCN agency) from May to July 2022; the responses were analyzed to determine the characteristics of the HCNs and HCN agencies. Multiple regression analysis was conducted to determine the factors associated with HCNs’ psychological safety.

    Results:

    This study included 145 HCNs from 73 HCN agencies. The mean age of the HCNs was 43.46 years, and the mean score on the Japanese version of the psychological safety scale was 27.19. Psychological safety was significantly associated with HCNs’ perceptions of follow-up systems for adverse events (β = .355, p  < .001), perceptions of management’s attitude toward problem-solving (β = .309, p  < .001), and management’s efforts to create a consultative environment (β = .183, p  = .009). Furthermore, psychological safety was negatively correlated with agency-level factors, including the average number of visits per month by HCNs (β = −.184, p  = .012) and the use of social networking services (SNS) for business communication in daily work (β = −.173, p  = .018).

    Conclusions:

    Supportive management practices are crucial to shaping the psychological safety of Japanese HCNs, whereas heavy workloads and frequent SNS use for communication may hinder it; thus, organizational improvements and workload adjustments are necessary.

  • COVID-19感染拡大が地域住民や地域活動に及ぼす影響とポストコロナ社会での住民主体型地域活動再興に向けた課題の検討

    　View Summary

    新型コロナウイルス感染症(COVID-19)感染拡大(コロナ禍)が地域住民や地域活動に及ぼす影響とポストコロナ社会での住民主体型地域活動再興へ向けた課題の検討に資することを目的とした。2023年2月～3月に、神奈川県A市の1地区の自治会所属世帯(1400世帯)を対象に、世帯の中で「地域での活動・行事に参加している/関心がある者」1名へコロナ禍における困りごと、心理的ストレス指標(Kessler Psychological Distress Scale:K6)を用いた心理的ストレスなどについて質問紙調査を行い、318名より有効回答を得た。同市においてコロナ禍前より市から事業承認を受け、地域住民を対象とした地域活動である「地域の縁側」を実施している運営6団体(17名)を対象に、「コロナ禍での[地域の縁側]の活動再開や継続のための取り組み」などについて半構成的面接を行った(調査期間:2022年10月～2023年3月)。その結果、質問紙調査では、対象の70%近くが地域活動への参加頻度の減少を経験しており、K6を用いた精神的健康評価では31.5%が支援を必要とする中等症以上のストレスを有していることが分かった。半構成的面接では、コロナ禍での「地域の縁側」活動継続のための取り組みとして、「運営メンバー間での意見交換」「自分たちの活動が担う社会的役割の再確認」「活動再開/継続のメリットとリスクの検討」「活動再開/継続のための情報収集」「コロナ禍で自分たちが活用できる資源の検討」「コロナ禍での新しい活動場所/方法の検討と実践」などの【自分たちの活動への社会的役割認識を根本とした柔軟で臨機応変な取り組み】が行われていることが分かった。

  • Association between obtaining injury prevention information and maternal and child health services during COVID-19

    BMC Health Services Research (Springer Science and Business Media LLC)  24 ( 1 )  2024.03

    　View Summary

    Abstract

    Background

    Coronavirus disease 2019 disrupted the delivery of public maternal and child health services to caregivers of preschool children, leading to decreased opportunities for injury prevention education. We aim to 1) explore the timing, content, and methods of providing injury prevention information desired by pregnant women and mothers and 2) identify mothers who experienced difficulty in obtaining injury prevention information owing to reduced maternal and child health services.

    Methods

    From March 24 to 29, 2022, we conducted a population-based cross-sectional study and web-based survey. Of the registered monitors of the internet research company Rakuten Insight, 675 mothers raising their first child aged 0–2 during the COVID-19 period (February 2020 to March 2022) were included in the analysis.

    Results

    Over half of the mothers wanted injury prevention information throughout their pregnancy. They preferred receiving information through traditional face-to-face services provided by local governments, such as antenatal classes or checkups. However, 34.1% of mothers said they did not obtain the information they needed; this was particularly true of unemployed mothers, had children aged 0–1, and had children with illnesses requiring hospital visits.

    Conclusions

    Mothers who could not obtain injury prevention information were originally disadvantaged mothers concerning access to information. The decrease in maternal and child health services may have widened this information gap. These findings can inform recommendations for caregivers, particularly those susceptible to information gaps during emergencies, and offer insights into future injury prevention education strategies.

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

    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.

    　View Summary

    医療現場で発生した事故やインシデントは、その発生報告だけでなく、発生要因や再発予防策を検討する組織学習の過程を経て医療安全の実現に貢献する。特に医療や看護など、業務上の失敗が致命的な結果となり得るハイリスク組織では、他組織の失敗から間接的に学ぶ代理学習が不可欠であるが、訪問看護サービスには、代理学習の機会を提供する社会システムが存在しない。
    本研究では、訪問看護師を対象に、事故等の発生情報や、各訪看ＳＴ内での再発予防策等の検討過程に関する情報について、訪看ST間で共有／参照できるオンラインシステムを開発、展開し、訪看STへの代理学習の機会付与が、訪看STの安全管理方略へ与える効果を比較検証する。

    　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%).
