INTRODUCTION: Seasonal influenza vaccination for the elderly is highly recommended during the COVID-19 pandemic. In Japan, the amount of subsidy for influenza differs among municipalities. Thus, we investigated the amount of and variation in subsidy for influenza vaccination for the elderly in 2020. METHODS: This was an ecological study of 1,922 municipalities in Japan. The amount of subsidy for influenza vaccines for the elderly in each municipality was surveyed through websites or via telephone. Geographic and financial data for municipalities and prefectures were obtained from the open data. The amount of co-payment for the influenza vaccine and the geographical and financial status of each municipality were compared, according to the aging rate. Univariate logistic regression analysis was performed to explore factors related to the free influenza vaccine. RESULTS: Municipalities with higher aging rates tended to have higher median co-payments for vaccines in 2020. (0 yen vs 1000 yen, p < 0.001) In addition, they tended to have worse financial conditions and lower per capita incomes. A similar trend was observed in the analysis by prefecture, i.e., a higher influenza mortality rate in prefectures with a higher aging rate. Despite having lower incomes, municipalities and prefectures with higher aging populations had higher mortality rates from influenza and higher co-payments for influenza vaccination. CONCLUSIONS: In Japan, there is a disparity among elderly people; areas with an aging population have higher co-payments for influenza vaccines despite lower incomes, suggesting that the government needs to implement corrective measures to reduce this disparity.

Background: Few studies have examined whether family caregivers' own primary care providers can affect caregiving-specific well-being, such as caregiver stress. In this pilot study, we explored whether primary care experiences when family caregivers report as patients were associated with the stress of caregiving. Methods: We used cross-sectional data from a survey conducted in Japan between November and December 2020. We recruited family caregivers aged 40–74 years who were caring for community-dwelling adults with chronic conditions. We assessed primary care experience using the Japanese version of the Primary Care Assessment Tool Short Form (JPCAT-SF) and caregiver stress using the Japanese short version of the Zarit Caregiver Burden Interview. Results: In total, 406 family caregivers were included in the analysis. The mean JPCAT-SF total score was 42.1 out of 100 points. The proportion of caregivers who had higher caregiver stress was 48.8%. After adjusting for possible confounders, the JPCAT-SF score was found to be significantly associated with caregiver stress (lower stress = 0 vs. higher stress = 1; adjusted prevalence ratio per 1 SD increase in JPCAT-SF score = 0.89; 95% CI 0.80–0.98). Among the subscales of the JPCAT-SF, longitudinality, and comprehensiveness (services available) were associated with caregiver stress. Conclusions: Better primary care experiences when family caregivers reported as patients were associated with lower caregiver stress. Longitudinality, which includes focusing attention on the individual as a whole person, and comprehensiveness in the context of building provider-patient relationships that make consultation easier when needed, were associated with lower stress.

BACKGROUND: Self-assessment of professionals' interprofessional competency is meaningful for benchmarking oneself and helping to identify training needs. We aimed to clarify differences in self-assessment of interprofessional competency in Japan by profession and type of facility. METHODS: We conducted a cross-sectional study using a web survey among primary healthcare providers in Japan, especially members of the Japan Primary Care Association, between June and October 2020. After sampling using the e-mail list, we used an exponential nondiscriminative snowball method as purposive sampling through key professional informants between November 2020 and February 2021. The questionnaire covered items including participant demographics (age, gender, years of experience as professionals, years of experience working at the current institution, attendance type (regular or part-time work), administrative experience, profession, and facility type) and included the Japanese version of the Self-assessment Scale of Interprofessional Competency (JASSIC). Differences between healthcare professions (physician, nurse, pharmacist, rehabilitation therapist, and social worker) and between types of facility (university hospital, medium-sized hospital, small hospital, and clinics) were compared using the Kruskal-Wallis test. RESULTS: A total of 593 people responded to the survey. Their mean age was 41.2 ± 11.3 years, and 312 (52.6%) were female. JASSIC scores of physicians and social workers were significantly higher than those of rehabilitation therapists (p < 0.01). Concerning facilities, professionals working in clinics rated themselves higher than those in medium-sized hospitals (p < 0.01). CONCLUSIONS: We revealed that self-assessment of interprofessional competency in Japan varied by profession and type of facility.

Since early 2020, the COVID-19 pandemic has been a pervasive global issue eliciting various responses at the local level. Drawing upon anthropologist Yanai Tadashi's concept “body social,” this article aims to discuss what Japanese general practitioners have attempted to protect from the uncontrollable “waves” of the pandemic. Based on the vivid narratives about their shifting patterns of responses from July 2020（the beginning of the so-called “second wave”） to February 2021（the end of the “third wave”）, it elucidates how the general practitioners' imaginings of the “body social” to be protected were flexibly transformed according to their perceptions of the pandemic situations in their immediate surroundings, from their physical bodies to their medical institutions, to their chiiki （communities）．Their engagements in expanding cooperation with other medical and non-medical actors to protect their chiiki as “body social” pose valuable lessons for anthropologists of infectious diseases and disasters beyond the realm of medicine.

© Objective Currently, use of social networking services (SNSs) for interprofessional collaboration is increasing. However, few studies have reported on virtual interprofessional interactions in community healthcare services. Revealing such structural characteristics of the networks can provide insight into the functions of the interprofessional information-sharing network and lead to smoother collaboration. Thus, we aimed to explore the structure of SNS-based information-sharing clinical networks. Design Social network analysis (SNA). Setting We selected a community in City X in Japan. Data collection We analysed SNS-based information-sharing clinical network data linked to patients receiving home medical care or care services between January and December 2018. A network was created for each patient to allow healthcare professionals to post and view messages on the web platform. In the SNA, healthcare professions registered in a patient group were represented as nodes, and message posting/viewing relationships were represented as links in the patient network. We investigated the structural characteristics of the target networks using several measures for SNA, including indegree centrality and outdegree centrality, which reflect the number of incoming and outgoing links to/from a node, respectively. Additionally, the professions forming the most central nodes were investigated based on their ranking to identify those with a central role in the networks. Finally, to compare the networks of nursing care levels 1-3 (lighter care requirement) and those with nursing care levels 4-5 (heavier care requirement), we analysed the structural differences in the networks and investigated the roles of healthcare professionals using centrality measures of nodes. Results Among 844 groups, 247 groups with any nursing care level data were available for analysis. Increasing nursing care level showed higher density, reciprocity and lower centralisation. Healthcare professions with high indegree centrality (physicians, care workers and physical therapists) differed from those with high outdegree centrality (home care workers, physical therapists, and registered dieticians). Visiting nurses and nurses in the clinic played a central role, but visiting nurses tended to have higher indegree and outdegree centrality, while nurses in the clinic had higher closeness and betweenness centrality in networks with heavier care requirement. Conclusion The SNS-based information-sharing clinical network structure showed that different professions played some form of a central role. Associations between network structures and patient outcomes, cost effectiveness and other factors warrant further investigation.
