    JAMA Network Open, 8, 12, e2549457, e2549457, American Medical Association (AMA), 2025年12月12日, [査読有り], [筆頭著者, 責任著者], [国際誌]
    英語, 研究論文(学術雑誌), Importance

    Hospitalization in older adults leads to a decline in daily living activities, and countries experiencing demographic aging face an increase in hospitalization rates and health care costs. Health care systems that can reduce the probability of ambulatory care–sensitive condition (ACSC) hospitalization among older populations are needed.

    Objective

    To comprehensively assess the association between regional factors and the probability of ACSC hospitalization among older adults and the extent to which regional factors explain this probability.

    Design, Setting, and Participants

    A retrospective cohort study in Hokkaido prefecture, Japan, focused on participants aged 65 years or older who were covered by community-based or older-age health insurance (all adults aged 72 years and older) and had at least 2 medical visits between July and December 2022. The patients were followed up until December 2023.

    Exposure

    Explanatory variables included municipal-level factors of residence categorized according to the Andersen behavioral model, which conceptualizes health service use as a function of predisposing, enabling, and need factors. At the municipal level, 9 predisposing, 11 enabling, and 10 need factors were included.

    Main Outcomes and Measures

    The primary outcome was the binary variable of whether an individual was hospitalized for ACSCs between January and December 2023.

    Results

    Among the 1 272 960 participants (median [IQR] age, 78 [73-84] years; 762 118 [59.9%] women), 51 623 (4.1%) had ACSC hospitalizations: 9492 for acute conditions, 41 271 for chronic conditions, and 3779 for vaccine-preventable conditions. A multilevel logistic regression analysis with individuals for level 1 and municipalities for level 2 revealed that 6.0% of the variance was attributable to municipal factors. Lower odds of hospitalization were associated with more clinics (odds ratio [OR], 0.933; 95% CI, 0.881-0.988), long-term care rehabilitation beds (OR, 0.996; 95% CI, 0.993-0.999), and higher financial power (OR, 0.359; 95% CI, 0.236-0.548); home care support clinics showed a similar direction (OR, 0.807; 95% CI, 0.636-1.024). Higher odds were associated with more nursing home beds (OR, 1.004; 95% CI, 1.000-1.009), a higher proportion of older adults living alone (OR, 1.073; 95% CI, 1.032-1.116), and a higher income (OR, 1.0004; 95% CI, 1.0001-1.0006).

    Conclusions and Relevance

    In this cohort study of older adults in Japan, ACSC hospitalizations were less likely in municipalities with more outpatient, in-home, and rehabilitation care resources and stronger financial capacity and more likely in those with more nursing home beds, greater social isolation, and higher income levels., 36703687

    英語, 研究論文(学術雑誌), Abstract

    Introduction

    High-income countries face the urgent task of reducing healthcare spending incurred by low-value care. However, evidence is limited as to whether high-cost or low-cost low-value care services contribute more to total unnecessary healthcare spending, especially outside the United States.

    Methods

    Using a claims database covering all age groups in Japan from April 2022 to March 2023 (approximately 2 million beneficiaries, or 2% of the total population), we examined 52 low-value care services using two versions of claims-based measures with different sensitivities and specificities (narrower and broader definitions).

    Results

    We identified 3.1 million (narrower) to 3.7 million (broader) episodes of low-value care services, accounting for 42.6–67.2 million USD, or 0.7–1.0% of total healthcare spending. In the narrower definition, lower-cost services (<80 USD per service) contributed to virtually all episodes of low-value care and 67% of total unnecessary healthcare spending—far exceeding the 33% attributed to the higher-cost services (≥80 USD).

    Conclusion

    This finding suggests that compared to focusing solely on higher- low-value care low-value care services, targeting the reduction of frequently performed, lower-cost low-value care services may be a more effective and efficient strategy for reducing wasteful spending.
  • Changes in inpatient and outpatient stroke admissions during COVID-19: a difference-in-differences analysis based on claims data from 242 acute care hospitals in Japan
    Kazuhiro Abe, Shota Shibata, Atsushi Miyawaki, Ichiro Kawachi
    BMJ Public Health, 3, 2, e001958, e001958, BMJ, 2025年09月, [査読有り], [筆頭著者, 責任著者], [国際共著], [国際誌]
    英語, 研究論文(学術雑誌), Introduction

    While COVID-19 has been associated with an elevated stroke risk due to its prothrombotic and inflammatory effects, previous studies have reported a decreased number of stroke hospitalisations during COVID-19. Patients with a stroke who could not be admitted might have been followed up in outpatient settings of these hospitals. Our study aimed to investigate the change in the number of patients who had a stroke admitted to inpatient and outpatient settings during COVID-19.

    Methods

    A difference-in-differences design using claims data in 242 acute-care hospitals was adopted to examine stroke admissions in Japan, contrasting the pre-pandemic period (2015–2019) to the pandemic period (2020). The Japanese government’s declaration of emergency in April 2020 was considered an exogenous shock. The outcomes were the numbers of ischaemic stroke (both embolic and non-embolic), intracerebral haemorrhage and subarachnoid haemorrhage admissions, with in-hospital mortality rates, modified Rankin Scale and procedure uses.

    Results

    From a total of 27 631 stroke cases (44.3% women, median age 75 years (IQR 66–83)), no statistically significant changes were observed in the overall count of stroke admissions during the pandemic. A decrease in ischaemic stroke hospitalisations was detected (incidence-rate ratios (95% CI), 0.83 (0.73 to 0.95)), which was somewhat offset by an increasing trend for patients treated in the outpatient setting (1.06 (0.91 to 1.22)). No significant differences were found in in-hospital mortality rate, proportion of severe modified Rankin Scale at discharge and thrombolysis treatment rate. Rates of mechanical thrombectomy in ischaemic stroke were reduced (0.60 (0.36 to 0.99)), and length of stay was reduced for all types of stroke except intracerebral haemorrhage.

    Conclusion

    When considering both inpatient and outpatient admissions for stroke, we found no statistically significant change in the number of stroke admissions in 2020 in Japan. In addition, our findings suggest that acute stroke inpatient care, at least during 2020, was appropriately managed despite limited resources., 36703687

    Age and ageing, 54, 9, 2025年08月29日, [査読有り], [国際誌]
    英語, 研究論文(学術雑誌), BACKGROUND: Little is known about how ambulatory care sensitive condition (ACSC)-related readmissions can be reduced in acute care settings. OBJECTIVE: This study examined the association between transitional care for hospitalised older patients with ACSC and ACSC-related readmissions. METHODS: This retrospective observational cohort study included patients aged 65 years and older admitted with ACSC as the primary diagnosis from 1 April 2022 to 31 January 2023, using linked data from the Diagnosis Procedure Combination and the medical functions of the hospital beds database. The primary outcomes were cumulative readmissions within 1-7, 1-14, 1-21, 1-30 and 1-60 days, analysed using inverse probability treatment weighting regression models. RESULTS: Among 85 582 patients from 711 hospitals, 39 916 (46.6%) were female, with a median age of 82 years (interquartile range: 75-88); 57 127 (66.8%) patients received transitional care. The overall readmission rates were 2.9%, 6.0%, 8.7%, 11.4% and 17.5% among total hospitalisations within 7, 14, 21, 30 and 60 days, respectively. Overall, transitional care was associated with reduced odds of ACSC-related readmission, with odds ratios ranging from 0.72 (95% CI: 0.65-0.78) within 7 days to 0.91 (95% CI: 0.87-0.95) within 60 days. The association between transitional care and readmission varied by ACSC category. In chronic ACSC, the association was strongest for 7-day readmission, followed by a downward trend. In acute and vaccine-preventable ACSC, the association was strongest for 7-day readmission but levelled off after 21 days. CONCLUSIONS: Transitional care in acute care hospitals may be associated with a reduced risk of early readmissions due to ACSC when older patients are hospitalised., 36703687

    英語, 研究論文(学術雑誌), ABSTRACT

    During the COVID‐19 pandemic, a decline in various infectious disease cases was observed. However, changes in dermatological infectious diseases, particularly cellulitis, and the potential impact of delayed consultations on severe cases have not been fully explored. To investigate changes in the number of cellulitis patients and severe cases during the COVID‐19 pandemic. We employed a difference‐in‐differences (DID) design using a de‐identified claims database from 242 acute‐care hospitals across Japan to compare the pre‐pandemic period (January 1, 2015, to December 31, 2019) with the pandemic period (January 1, 2020, to December 31, 2020). The national state of emergency, declared by the Japanese government in April 2020 in response to COVID‐19, was treated as an exogenous shock. The study analyzed outpatient, inpatient, and total cases, sepsis and bacteremia complications, ambulance transport rates, length of hospital stay, and inpatient comorbidities. A total of 28 673 cellulitis cases were analyzed (24 256 from 2015 to 2019; 4417 in 2020). Severity indicators included hospitalization (8.2%), sepsis (4.1%), bacteremia (1.7%), and ambulance transport (17.0%). In the DID analysis, a significant decrease was observed in total cellulitis cases (incidence rate ratio [IRR]: 0.91; 95% confidence interval [CI]: 0.85–0.97), outpatient cases (IRR: 0.92; 95% CI: 0.86–0.98), and inpatient cases (IRR: 0.81; 95% CI: 0.66–0.99). No significant differences were found in sepsis (IRR: 0.53; 95% CI: 0.26–1.10), bacteremia (IRR: 0.73; 95% CI: 0.19–2.86), ambulance transport (IRR: 0.81; 95% CI: 0.50–1.29), or length of hospital stay (IRR: 0.83; 95% CI: 0.66–1.03). During the pandemic, the number of cellulitis cases treated in Japanese acute‐care hospitals decreased without a significant rise in severe cases, suggesting the possibility that avoidance of medical consultations may not have worsened outcomes. Pandemic‐related behavioral changes may have contributed to the reduced incidence., 36703687

    英語, 研究論文(学術雑誌), IMPORTANCE: Evidence is limited regarding the physician characteristics associated with the provision of low-value services in primary care, especially outside of the US. OBJECTIVE: To measure physician-level use of 10 low-value care services that provide no net clinical benefit and to investigate the characteristics of primary care physicians who frequently provide low-value care in Japan. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional analysis used a nationwide electronic health record database linked with claims data in Japan to assess visits by adult patients (age ≥18 years) to a solo-practice primary care physician from October 1, 2022, through September 30, 2023. Data analysis was performed from June 2024 to February 2025. MAIN OUTCOMES AND MEASURES: Multivariable-adjusted composite rate of low-value care services delivered per 100 patients per year, aggregated across 10 low-value measures, after accounting for case mix and other characteristics. RESULTS: Among 2 542 630 patients (mean [SD] age, 51.6 [19.8] years; 58.2% female) treated by 1019 primary care physicians (mean [SD] age 56.4 [10.2] years; 90.4% male), 436 317 low-value care services were identified (17.2 cases per 100 patients overall). Nearly half of these low-value care services were provided by 10% of physicians. After accounting for patient case mix, older physicians (age ≥60 years) delivered 2.1 per 100 patients (95% CI, 1.0-3.3) more low-value care services than those younger than 40 years; not board-certified physicians delivered 0.8 per 100 patients (95% CI, 0.2-1.5) more than general internal medicine board-certified physicians; physicians with higher patient volumes delivered 2.3 per 100 patients (95% CI, 1.5-3.2) more than those with low patient volumes; and physicians practicing in Western Japan delivered 1.0 per 100 patients (95% CI, 0.5-1.5) more than those in Eastern Japan. CONCLUSIONS AND RELEVANCE: The findings of this cross-sectional analysis suggest that low-value care services were common and concentrated among a small number of primary care physicians in Japan, with older physicians and not board-certified physicians being more likely to provide low-value care. Policy interventions targeting at a small number of certain types of physicians providing large quantities of low-value care may be more effective and efficient than those targeting all physicians uniformly.

    英語, 研究論文(学術雑誌), Objectives

    In April 2012, the Japanese government launched a new nursing service called the nursing small-scale multifunctional home care (NSMHC) to meet the nursing care demands of individuals with moderate-to-severe activities of daily living (ADLs) dysfunction and who require medical care, thereby allowing them to continue living in the community. We aimed to preliminarily analyse the characteristics of first-time users of NSMHC service.

    Design

    This pooled cross-sectional study used the Japanese long-term care insurance (LTCI) claims data from the users’ first use of NSMHC (from April 2012 to December 2019).

    Setting

    NSMHC includes nursing home visits, home care, daycare, overnight stays and medical treatment.

    Participants

    The study population included LTCI beneficiaries who received their first long-term care requirement certification in Japan from April 2012 onwards, died between April 2012 and December 2019, and used any LTCI service at least once.

    Results

    Among the 836 563 individuals who used any LTCI service at least once, 3957 (0.47%) used NSMHC. We analysed 3634 individuals without any missing data regarding long-term care requirement certification. Most individuals were aged 80 years or older, with 64.3% requiring care level 3 or above, indicating complete assistance with ADLs. Regarding ADLs in individuals with dementia, 70.6% were at level 2 or below, indicating they can live almost independently even with dementia. A large proportion of NSMHC users availed the service approximately 6 months before death, with no prior use of any LTCI services; they continued using the service for around 4 months, although some people continued to use NSMHC until their month of death.

    Conclusions

    Using individual data on nationwide LTCI, we described the characteristics of first-time users of NSMHC among those who died within 7.5 years from the first certification of care needs. Further studies are needed to investigate the effect of NSMHC use on user outcomes.

    英語, 研究論文(学術雑誌), IMPORTANCE: The COVID-19 pandemic may have played a role in the deterioration of access to medical care for ambulatory care-sensitive conditions (ACSCs). OBJECTIVE: To ascertain whether the number of in-hospital deaths and in-hospital mortality rate associated with ACSC changed after the declaration of the COVID-19 national state of emergency in Japan. DESIGN, SETTING, AND PARTICIPANTS: This cohort study used a difference-in-differences design to compare outcomes for ACSC in the period before (January 1, 2015, to December 31, 2019) vs the period after (January 1, 2020, to December 31, 2020) Japan declared a national state of emergency for the COVID-19 pandemic. Analyses used discharge summary data from 242 acute care hospitals across Japan. The sample comprised unscheduled hospitalizations of patients with ACSC during the study period (January 1, 2015, to December 31, 2020). Data analyses were performed between August 16 and December 7, 2022. EXPOSURE: The declaration of the COVID-19 national state of emergency announced by the Japanese government in April 2020 was considered to be an exogenous shock. MAIN OUTCOMES AND MEASURES: Primary outcomes were the ACSC-associated number of in-hospital deaths, number of hospitalizations, and in-hospital mortality rate. RESULTS: A total of 28 321 ACSC-related hospitalizations were observed involving 15 318 males (54.1%), with a median (IQR) age of 76 (58-85) years. The number of in-hospital deaths was 2117 (7.5%). The number of hospitalizations decreased overall (incidence rate ratio [IRR], 0.84; 95% CI, 0.75-0.94), for chronic conditions (IRR, 0.84; 95% CI, 0.77-0.92), and for vaccine-preventable conditions (IRR, 0.58; 95% CI, 0.44-0.76). However, in-hospital deaths (IRR, 1.66; 95% CI, 1.15-2.39) and in-hospital deaths within 24 hours of hospital arrival (IRR, 7.27 × 106; 95% CI, 1.83 × 106 to 2.89 × 107) increased for acute conditions. The in-hospital mortality rate increased for acute conditions (IRR, 1.71; 95% CI, 1.16-2.54), and the 24-hour in-hospital mortality rates also increased overall (IRR, 1.87; 95% CI, 1.19-2.96), for acute conditions (IRR, 2.15 × 106; 95% CI, 5.25 × 105 to 8.79 × 106), and for vaccine-preventable conditions (IRR, 4.64; 95% CI, 1.28-16.77). CONCLUSIONS AND RELEVANCE: This cohort study found that in Japan, the number of in-hospital deaths increased after the declaration of the COVID-19 national state of emergency in 2020, particularly for acute ACSC and deaths within 24 hours of hospital admission. This finding suggests that access to good-quality primary care and inpatient care for patients with acute ACSC may have been compromised during the pandemic., 36703687

    英語, 研究論文(学術雑誌), Importance: The provision of in-home and community end-of-life care has emerged as an important policy issue for aging populations around the world. Despite most patients expressing the wish to die at home (as opposed to in the hospital), substantial geographic variation persists in the prevalence of in-home death at the end of life. Objective: To assess the association of municipal characteristics with variation in the place of death among care-dependent older people in Japan. Design, Setting, and Participants: In this cross-sectional study using multilevel logistic regression, analyses were performed using national claims data under Japan's long-term care insurance system. The study population included long-term care insurance beneficiaries 65 years and older who died in 2015, excluding those who died from external causes, such as unintentional injuries. Data analyses were conducted from January 1 to April 31, 2021. Exposures: Predisposing, enabling, and need factors at the individual and municipal levels according to a behavioral model. Main Outcomes and Measures: The outcome was whether individuals died at home or not. Results: This cross-sectional study analyzed 544 836 decedents (median [IQR] age, 87 [81-91] years; 300 142 [55.1%] female). The proportion of in-home deaths was 10.3%. In the multilevel null model, 7.2% of the variance in the place of death was associated with municipal-level characteristics. Municipal characteristics were associated with more of the variance than were prefectural characteristics (2.7%). The largest proportional change (7.3%) in variance at the municipality level was observed when enabling factors (ie, medical and long-term care resources) were added to the model. Municipalities with a high proportion of in-home death were more likely to have a higher supply of clinics, physicians, and care workers providing in-home services per population, as well as a lower number of hospital beds and long-term care facility workers per population. Conclusions and Relevance: In this cross-sectional study, municipal characteristics explained a substantial proportion of the geographic variance in in-home death in Japan. These results suggest that municipal policy makers need to ensure an adequate supply of clinics, physicians, and care workers providing in-home services to meet the preferences of care-dependent older people who wish to spend their final days at home., 29382350

    英語, 研究論文(学術雑誌), Abstract
    Background
    Japan has promoted end-of-life care at home and in long-term care facilities, and the total proportion of in-hospital deaths has decreased recently. However, the difference in trends of in-hospital deaths by the cause of death remains unclear. We investigated the variation in trends of in-hospital deaths among older adults with long-term care from 2007 to 2017, by cause of death and place of care.



    Methods
    Using the national long-term care insurance registry, long-term care claims data, and national death records, we identified people aged 65 years or older who died between 2007 and 2017 and used long-term care services in the month before death. Using a joinpoint regression model, we evaluated time trends of the proportion of in-hospital deaths by cause of death (cancer, heart diseases, cerebrovascular diseases, pneumonia, and senility) and place of care (home, long-term care health facility, or long-term care welfare facility).



    Results
    Of the 3,261,839 participants, the mean age was 87.0 ± 8.0 years, and 59.2% were female. Overall, the proportion of in-hospital deaths decreased from 66.2% in 2007 to 55.3% in 2017. By cause of death, the proportion of in-hospital deaths remained the highest for pneumonia (81.6% in 2007 and 77.2% in 2017) and lowest for senility (25.5% in 2007 and 20.0% in 2017) in all types of places of care. The joinpoint regression analysis showed the steepest decline among those who died of senility, especially among long-term care health facility residents.



    Conclusions
    The findings of this nationwide study suggest that there was a decreasing trend of in-hospital deaths among older adults, although the speed of decline and absolute values varied widely depending on the cause of death and place of care.

    英語, 研究論文(学術雑誌), AIM: The study assessed the association between boosting the workforce supply by types of long-term care services and in-home deaths among older people at the municipality level. METHODS: A fixed-effect panel data analysis was conducted using administrative data for every 3 years from 2008 to 2014. The outcome was the proportion of home deaths, excluding those due to external factors, such as suicide or accident. The explanatory variables were the full-time equivalent numbers of care workers engaged in in-home services, day services, short-stay services, and long-term care facilities per 1000 population aged 65 years and older. Ordinary least squares estimation was conducted, with standard errors corrected for clustering at the prefecture level, adjusting the covariates. RESULTS: Analysis included 1706 municipalities. One care worker increase providing day services per 1000 population aged 65 years and older was associated with a 0.09% increase in the proportion of deaths at home (95% CI: 0.008-0.17). Although statistically non-significant, the number of care workers providing in-home services was positively associated with the proportion of home deaths, whereas the number of those providing short-stay services and providing long-term care facilities and nursing home services were inversely associated with home deaths. CONCLUSIONS: Given the increased number of care-dependent older people who opt to stay at home until death, and their informal caregivers who have the burden and stress of care, the findings suggest that policymakers should ensure that the number of care workers for day services is sufficient for supporting care recipients and informal caregivers.

    英語, 研究論文(学術雑誌), OBJECTIVES: Despite the significant utilization of long-term care (LTC) services at the end of life, evidence on the trajectory of LTC expenditure in later life is scarce. This study aims to identify distinct trajectories of LTC expenditure in the last 5 years of life and to examine whether these trajectories differ according to cause of death. DESIGN: A nationwide retrospective longitudinal cohort study based on linked data of National LTC Claims and the Japan's National Vital Statistic. SETTING AND PARTICIPANTS: Participants comprised decedents aged 70 years or older and who died in 2017. METHODS: We assessed 5 years of monthly LTC expenditure among participants and applied group-based trajectory model to identify distinct trajectories of LTC expenditure. Subsequently multinominal logistic regression analysis was performed to investigate how these trajectories vary according to cause of death. RESULTS: Among 1,124,335 decedents, 4 distinct trajectories of LTC expenditure were identified: persistently low (58.5%), late increase (9.8%), progressive increase then late decrease (8.8%), and persistently high (22.9%). Approximately 80.7% of total LTC expenditure was spent by the persistently high group. After adjustment for age and sex; deaths due to age-related physical debility and dementia were associated with persistently high LTC expenditure. CONCLUSIONS AND IMPLICATIONS: Ongoing discussions of LTC policy and reducing LTC expenditure may be more effective when emphasizing persistently high spenders. In addition, budget allocation for LTC at the end of life should be combined with data for health conditions., 29382350

    Journal of epidemiology, 2020年06月13日, [査読有り], [国内誌]
    英語, 研究論文(学術雑誌), BACKGROUND: With increasing age globally, more people may become vulnerable to food choking. We investigated the nationwide epidemiology of food choking deaths in Japan. METHODS: Using Japanese Vital Statistics death data between 2006 and 2016, we identified food choking deaths based on the 10th revision of the International Statistical Classification of Diseases code W79 (Inhalation and ingestion of food causing obstruction of respiratory tract) as a primary diagnosis. We assessed the demographics of people with food choking deaths; temporal trends of food choking deaths by the year (overall and by age group), the day of year; and prefecture variations. RESULTS: Overall, 52,366 people experienced food choking deaths (median age, 82 years, 53% were male, and 57% occurred at home). The highest numbers occurred January 1-3, and were lowest in June. Despite a stable total number of cases at around 4,000 yearly, from 2006 to 2016 the incidence proportion declined from 16.2 to 12.1 per 100,000 population among people aged 75-84 years. Among people ≥85 years, the incidence proportion peaked at 53.5 in 2008 and decreased to 43.6 in 2016. The number of food choking deaths varied by prefecture. CONCLUSIONS: There are temporal and regional variations of food choking deaths in Japan, possibly due to the consumption of Japanese rice cake (mochi), particularly over the New Year's holiday.

    英語, 研究論文(学術雑誌), OBJECTIVES: To assess the association between receiving the certified care workers' home care service, which is provided by non-medical professionals prior to a patients' death and the probability of a home death. DESIGN: Observational research using the full-time translated number of certified care workers providing home care service per member of the population aged 65 or above, during the year prior to patient's death per municipality as an instrumental variable. SETTING: The certified care workers' home care service covered by the public long-term care insurance (LTCI) system in Japan. PARTICIPANTS: In total, 1 613 391 LTCI beneficiaries aged 65 or above who passed away, except by an external cause of death, between January 2010 and December 2013 were included in the analysis. PRIMARY OUTCOME MEASURES: Death at home or death at other places, including hospitals, nursing homes and clinics with beds. RESULTS: Out of all participants, 173 498 (10.8%) died at home. The number of patients who used the certified care workers' home care service more than once per each month during 1, 2 or 3 months prior to the month of death numbered 213 848, 176 686 and 155 716, respectively. This was associated with an increased probability of death at home by 9.1% points (95% CI 2.9 to 15.3), 10.5% points (3.3 to 17.6) and 11.4% points (3.6 to 19.2), respectively. CONCLUSIONS: The use of the certified care workers' home care service prior to death was associated with the increased probability of a home death.

    研究者が自らの研究成果を世界に還元する代表的な方法は、原著論文を執筆し、学術誌に発表することである。しかしながら、意外にも研究者にとって論文の書き方に関するトレーニングを受ける機会は非常に少ない。多くの場合は出版社が催すイベントに自主的に参加したり、論文の書き方に関する書籍を読んだり、先行研究を手本としたり、先輩研究者に添削をしてもらうことで独学してきたのではないだろうか。世界の読者に対して効果的に研究成果を届けるために、他の研究者は何を意識して論文を執筆しているのだろうか。

    このセッションでは、ハーバード大学T. H. Chan公衆衛生大学院で教わる原著論文の書き方を事例を含めて紹介する。その上で、参加者自身の論文執筆や指導、査読の経験を基に、原著論文の各セクション(IMRAD、抄録、タイトル)の書き方についての悩みを共有し、互いのアイデアを学び合う機会を提供する。
    主な対象者は、これまで筆頭著者として一編以上の英語原著論文を学術誌に発表した経験がある者、もしくは現在執筆中である者である。尚、研究分野や研究方法によって原著論文の書き方にはバリエーションがあるが、ここでは学会員にとって出版する機会が多いであろう量的手法を用いた疫学分野の英語原著論文の執筆について議論する。

    研究者同士で切磋琢磨しながら、日本のプライマリ・ケア領域から発表される質の高い原著論文を益々増やしていこう。

  • UHC Day 2019 - Lesson and message from Japanese experience
    UHC Youth Network, 2019年12月, UHC Youth Network has made short movies for sharing the lesson and message from the history of UHC in Japan, one of the world models of UHC. We filmed the speech or interview from seven persons who know Japan’s UHC history well and who contribute to create and maintain the system of UHC in Japan as a politician, an administrative officer, a medical provider, an academic, a member of civil society organization, and a goodwill ambassador.

    They tell us what the difficulties of developing the UHC were, how they overcame the challenges, and the current situation of Japan’s UHC in the videos. Moreover, they have given youths useful messages to progress the UHC in our own country.
  • Universal Health Coverage - Message from Japanese Youth
    UHC Youth Japan, 2017年12月, This is the message film from Japanese Youth to the world. Japan has greatly developed Universal Health Coverage(UHC) for the past 60 years, and we have accomplished the chance to be well off by UHC. We want to promote how wonderful it is to live in the world of UHC, and will drive UHC forward taking the baton from the forerunners.

    A chance for all.
