RESUMEN
Objective: The Japanese government's physician workforce reform, which commenced in April 2024, introduced regulations on physicians' working hours. However, in areas facing physician shortages such as rural regions and surgical medical specialties, healthcare provision relies heavily on the extended working hours of each physician. The anticipated impact of this reform, when implemented, was significant. Materials and Methods: Using publicly available government data, we estimated the current working hours of physicians in various medical specialties in each prefecture across Japan. Subsequently, we calculated the ratio of surplus or deficit physicians when hypothetically assuming that all physicians adhered to the regulatory upper limit of 58.4 working hours per week nationwide. Results: Assuming that all physicians work to the regulated maximum, there would be a shortage of doctors in various medical specialties across Japan, such as surgery, neurosurgery, orthopedic surgery, obstetrics and gynecology, and emergency medicine. Geographically, shortages of doctors are observed in rural prefectures such as those in the Tohoku region, particularly in emergency- and surgery-related specialties, indicating a critical shortage of physicians in rural areas. Additionally, it has become evident that even in medical specialties with a calculated surplus of physicians nationwide, the margin of surplus is generally only a few percentage points. Conclusion: Currently, rural areas and surgical medical specialties in Japan have limited leeway in the physician workforce, and the strict application of workforce reform may lead to a severe shortage of physicians in these areas. It is noteworthy that as similar reforms may subsequently be implemented in other countries, analogous challenges would arise. Thus, the implementation of workforce reform requires a flexible approach to minimize its negative effects, which widen the existing disparity in the workforce.
RESUMEN
BACKGROUND: Physician shortage and maldistribution is an urgent health policy issue requiring resolution. Determination of factors associated with regional retention and development of effective policy interventions will help to solve this issue. The purpose of the present study was to identify factors associated with regional retention and discuss their policy implications. METHODS: We conducted a cross-sectional online survey from February to March of 2022 for graduates from regional quotas (special quotas for medical schools to select students engaged in community medicine) and Jichi Medical University (JMU) and students at 10 medical schools including JMU. Completed surveys were obtained from 375 graduates and 1153 students. Questions included intention to continue to work in their home prefecture in the future, as well as background information and potential factors associated with regional retention. In the analyses, regional quotas and JMU were referred to as community medicine-oriented programs and schools (CMPS). We performed logistic regression analyses to identify factors associated with regional retention. RESULTS: Among the students, scholarship-bonded obligatory service, satisfaction with current life, intention to belong to ikyoku (a traditional physician allocation/training system in Japanese medical schools), and interest in general practice/family medicine were significantly positively associated with regional retention. Among the graduates, satisfaction with training environment, intention to belong to ikyoku, and recommending their program to high school students were significantly positively associated with regional retention. For students of CMPS, satisfaction with the career development program was positively associated with future regional retention. For graduates, this association was observed only in the crude analysis. CONCLUSIONS: In addition to known factors such as interest in general practice/family medicine, intention to belong to ikyoku had a substantial impact on regional retention. The present results suggest that the career support system represented by ikyoku as well as a career development program are of potential importance for increasing regional retention through the mechanisms of a sense of belonging and a life-long education system. These findings provide useful information for the development of further policy interventions that interweave traditional and new systems to maximize their effectiveness.

The geographically inequitable distribution of physicians has long posed a serious social problem in Japan. The government tackled this problem by establishing and managing Jichi Medical University (JMU) and regional quotas (RQs) for medical schools. JMU/RQs recruit local students who hope to work as physicians in rural areas, educate them for 6 years without tuition (JMU) or with scholarship (RQs), and after graduation, assign them to their home prefectures for 9 years, including 4-6 years of rural service. JMU/RQs entrants now occupy 11.6% of all medical school entrants. While JMU/RQs have been shown to be highly effective in securing physicians for rural areas, ethical issues related to these policies have been raised, such as whether the government truly needs to implement these policies using tax money, and whether it is acceptable to limit the personal freedoms of the physicians. In this paper, we discuss these issues from the perspectives of social justice, utilitarianism, luck egalitarianism, liberty, medical professionalism and consistency with national health insurance and the Japanese Constitution. We conclude that JMU/RQs are necessary and ethically valid policies, and also propose some institutional improvements to better secure the integrity and maturity of these systems.
RESUMEN
BACKGROUND: Level of care-need (LOC) is an indicator of elderly person's disability level and is officially used to determine the care services provided in Japan's long-term care insurance (LTCI) system. The 2018 Japan Floods, which struck western Japan in July 2018, were the country's second largest water disaster. This study determined the extent to which the disaster affected the LOC of victims and compared it with that of non-victims. METHODS: This is a retrospective cohort study, based on the Japanese long-term care insurance claims from two months before (May 2018) to five months after the disaster (December 2018) in Hiroshima, Okayama, and Ehime prefectures, which were the most severely damaged areas in the country. A code indicating victim status, certified by a residential municipality, was used to distinguish between victims and non-victims. Those aged 64 years or younger, those who had the most severe LOC before the disaster, and those whose LOC increased even before the disaster were excluded. The primary endpoint was the augmentation of pre-disaster LOC after the disaster, which was evaluated using the survival time analysis. Age, gender, and type of care service were used as covariates. RESULTS: Of the total 193,723 participants, 1,407 (0.7%) were certified disaster victims. Five months after the disaster, 135 (9.6%) of victims and 14,817 (7.7%) of non-victims experienced the rise of LOC. The victim group was significantly more likely to experience an augmentation of LOC than the non-victim group (adjusted hazard ratio 1.24; 95% confidence interval 1.06-1.45). CONCLUSIONS: Older people who were affected by the disaster needed more care than before and the degree of care-need increase was substantially more than non-victims. The result suggests that natural disasters generate more demand for care services among the older people, and incur more resources and cost for society than before.

BACKGROUND: Floods and torrential rains are natural disasters caused by climate change. Unfortunately, such events are more frequent and are increasingly severe in recent times. The 2018 Japan Floods in western Japan were one of the largest such disasters. This study aimed to evaluate the effect of the 2018 Japan Floods on healthcare costs and service utilization. METHODS: This retrospective cohort study included all patients whose receipts accrued between July 2017 and June 2019 in Hiroshima, Okayama, and Ehime prefectures using the National Database of Health Insurance Claims. We used Generalized Estimating Equations (GEEs) to investigate yearly healthcare costs during the pre-and post-disaster periods, quarterly high-cost patients (top 10%), and service utilization (outpatient care, inpatient care, and dispensing pharmacy) during the post-disaster period. After the GEEs, we estimated the average marginal effects as the attributable disaster effect. RESULTS: The total number of participants was 5,534,276. Victims accounted for 0.65% of the total number of participants (n = 36,032). Although there was no significant difference in pre-disaster healthcare costs (p = 0.63), post-disaster costs were $3,382 (95% CI: 3,254-3,510) for victims and $3,027 (95% CI: 3,015-3,038) for non-victims (p < 0.001). The highest risk difference among high-cost patients was 0.8% (95% CI: 0.6-1.1) in the fourth quarter. In contrast, the highest risk difference of service utilization was in the first quarter (outpatient care: 7.0% (95% CI: 6.7-7.4), inpatient care: 1.3% (95% CI: 1.1-1.5), and dispensing pharmacy: 5.9% (95% CI: 5.5-6.4)). CONCLUSION: Victims of the 2018 Japan Floods had higher medical costs and used more healthcare services than non-victims. In addition, the risk of higher medical costs was highest at the end of the observation period. It is necessary to estimate the increase in healthcare costs according to the disaster scale and plan for appropriate post-disaster healthcare service delivery.

OBJECTIVES: As disasters become more frequent because of global warming, countries across the world are seeking ways to protect vulnerable older populations. Although these conditions may increase nursing home admission (NHA) rates for older persons, we know of no studies that have directly tested this hypothesis. DESIGN: This was a retrospective cohort study. SETTING AND PARTICIPANTS: We analyzed data from long-term care insurance (LTCI) users in 3 Japanese prefectures that incurred heavy damage from the 2018 Japan Floods, which is the largest recorded flooding disaster in national history. Specifically, we extracted NHA data from the LTCI comprehensive database, both for disaster-affected and unaffected individuals. METHODS: We employed the Cox proportional hazards model to calculate multivariate-adjusted hazard ratios (HRs) for NHAs within a 6-month period following the 2018 Japan Floods, with adjustments for potential confounding factors. RESULTS: Of the 187,861 individuals who used LTCI services during the investigated period, we identified 2156 (1.1%) as disaster affected. The HR for NHA was significantly higher for disaster-affected (vs unaffected) individuals (adjusted HR 3.23: 95% CI 2.88â3.64), and also higher than the HRs for older age (90-94 years vs 65-69 years: 2.29, CI 1.93â2.70), cognitive impairment (severe impairment vs normal: 1.40, CI 1.25â1.57), and physical function (bedridden vs independent: 2.27, CI 1.83â2.70). According to our subgroup analyses, the adjusted HR for disaster-affected individuals unable to feed themselves was 6.00 (CI 3.68â9.79), with a significant interaction between the 2 variables (P = .01). CONCLUSIONS AND IMPLICATIONS: Natural disasters increase the risk of NHA for older persons, especially those who are unable to feed themselves. Health care providers and policymakers should understand and prepare for this emerging risk factor.

Context: The association between primary aldosteronism and obesity, especially its sex difference, remains unknown. Objective: To assess the association for each subtype of primary aldosteronism with obesity parameters including visceral adipose tissue and differences between sexes. Methods: In this case-control study, 4 normotensive controls were selected for each case with primary aldosteronism. Multivariable conditional logistic regression models were used to estimate the association between each type of primary aldosteronism and obesity indicators. We used a random forest to identify which visceral or subcutaneous tissue areas had a closer association with disease status. Results: The study subjects included 42 aldosterone-producing adenoma cases (22 women) and 68 idiopathic hyperaldosteronism cases (42 women). In multivariable conditional logistic regressions, aldosterone-producing adenoma was significantly associated with body mass index only in men (odds ratio [OR] [95% CI)], 4.62 [1.98-10.80] per 2.89 kg/m2) but not in women (OR [95% CI], 1.09 [0.69-1.72] per 3.93 kg/m2) compared with the matched controls, whereas idiopathic hyperaldosteronism was associated with body mass index in both men (OR [95% CI], 3.96 [2.03-7.73] per 3.75 kg/m2) and women (OR [95% CI], 2.65 [1.77-3.96] per 3.85 kg/m2) compared with the matched controls. In random forests, visceral adipose tissue areas were the better predictor of both aldosterone-producing adenoma and idiopathic hyperaldosteronism than subcutaneous adipose tissue. Conclusions: Aldosterone-producing adenoma cases were obese among men, but not among women. Idiopathic hyperaldosteronism cases were obese among both men and women. Visceral adipose tissue may contribute to the pathophysiology of primary aldosteronism.
RESUMEN
INTRODUCTION: Solutions for geographic maldistribution of physicians is challenging around the world, but primary care specialists are expected to resolve this issue. This study compares the geographic distribution of family physicians in Japan and the USA, both of which are developed countries without a major system for physician allocation by the public sector; however, the two countries differ greatly in the maturity of family medicine (ie length of its history as part of the healthcare system and the population of qualified family medicine experts). METHODS: This cross-sectional comparative study used publicly available online databases for Japan in 2018 and 2017 in the USA. The municipalities in Japan and counties in the USA were divided into quintile groups according to population density. The number of family physicians per unit population in each group of areas was calculated, and was evaluated with a residual analysis. The geographic distribution of all physicians in Japan was simulated assuming that the proportion of family physicians among all physicians in Japan (0.16%) was increased to match that in the USA (11.8%). RESULTS: Of 320 084 physicians in Japan and 899 244 in the USA, 519 (77.2%) family physicians in Japan and 105 999 (100%) in the USA were included. The distribution of family physicians in Japan was noticeably shifted to areas with the lowest population density. In contrast, family physicians in the USA were distributed equally across areas. The distribution of physicians of other specialties (general internists, pediatricians, surgeons and obstetricians/gynecologists) was shifted heavily to areas with the highest population densities in both countries. The simulation analysis showed the geographic maldistribution of the total number of physicians improved substantially if the proportion of family physicians in Japan is increased to match that in the USA. CONCLUSION: The distribution of family physicians is more equitable than that of other medical specialists; however, an immature family medicine system can lead to an aggregation of family physicians in rural areas. This aggregation supports equity due to the broader scope of practice required by family physicians in rural areas. In countries where family medicine has not yet matured as a specialty, provided that the equitable aggregation of family physicians in rural areas can be maintained, increasing the number of family physicians as a proportion of the total number of physicians may improve the geographic maldistribution of the total number of physicians.

BACKGROUND: The frequency and intensity of natural disasters are increasing worldwide, which makes our understanding of disaster-related diseases more important than ever. Natural disasters cause mental stress and infectious diarrhea, but the causal relationship between disasters and a potential consequence of these conditions, irritable bowel syndrome (IBS), is unreported. The 2018 Japan Floods, which took place in July 2018 was one of the largest water disasters in Japan's recorded history. We investigate the change of drug prescriptions for IBS between disaster-suffers and non-sufferers throughout the disaster period to examine the relationship. METHODS: This is a retrospective cohort study based on the Japanese National Database of Health Insurance Claims and Specific Health Checkups in flood-stricken areas between July 2017 and June 2019. We included subjects older than 15 years of age who had visited a medical institution or been hospitalized in the hardest-hit areas of the disaster. Ramosetron, polycarbophil calcium, and mepenzolate bromide (IBS drugs) approved solely for the treatment of IBS in Japan were analyzed. The monthly rate of prescriptions for IBS drugs was compared between municipality-certified disaster victims and non-victims using a controlled interrupted time series analysis. For those who were not prescribed IBS drugs before the disaster (non-users), the occurrence of an IBS drug prescription after the disaster was evaluated using a multivariable logistic regression analysis adjusted for gender and age. RESULTS: Of 5,287,888 people enrolled, 32,499 (0.61%) were certified victims. The prescription rate for IBS drugs among victims increased significantly by 128% immediately after the disaster, while it was stable among non-victims. The trend for the post-disaster prescription rate among victims moved upward significantly when compared to non-victims (0.01% per month; 95% confidence interval (CI) 0.004-0.015; P = 0.001). Among non-users, the occurrence of an IBS drug prescription for victims was 0.71% and was significantly higher than non-victims (0.35%, adjusted odds ratio 2.05; 95% CI 1.81-2.32). CONCLUSIONS: The 2018 Japan Floods increased the rate of prescriptions for IBS drugs, suggesting that the disaster caused or worsened IBS among victims.

PURPOSE: Natural disaster has an impact on mental health. The 2018 Japan Floods, which took place in July 2018 were one of the largest water disasters in Japan's recorded history. We aimed to evaluate the change in the number of benzodiazepine prescriptions by physicians before and after the disaster. METHODS: A retrospective cohort study based on the National Database of Health Insurance Claims was conducted in the flood-stricken areas between July 2017 and June 2019. The subjects were divided between victims and non-victims according to certification by local governments. Members of both groups were then categorized into three groups based on their pre-flood use of benzodiazepines: non-user, occasional user, and continuous user. Difference-in-differences (DID) analysis with a logistic regression model was conducted to estimate the effect of the disaster among victims by comparing the occurrence of benzodiazepine prescriptions before and after the disaster. RESULTS: Of 5,000,129 people enrolled, 31,235 were victims. Among all participants, the mean prescription rate for benzodiazepines in victims before the disaster (11.3%) increased to 11.8% after the disaster, while that in non-victims (8.3%) decreased to 7.9%. The DID analysis revealed that benzodiazepine prescription among victims significantly increased immediately after the disaster (adjusted ratio of odds ratios (ROR) 1.07: 95% confidence interval 1.05-1.11), and the effect of the disaster persisted even 1 year after the disaster (adjusted ROR 1.2: 95% confidence interval 1.16-1.24). CONCLUSION: The flood increased the number of benzodiazepines prescriptions among victims, and the effect persisted for at least 1 year.

OBJECTIVE: To determine the impact of the 2018 Japan Floods, one of the largest water disasters in Japan, on the number of prescriptions for triptans and ergotamine (acute treatment). BACKGROUND: Natural disasters frequently occur worldwide and may cause psychological stress-related diseases. Acute migraine attacks can be triggered by psychological stress. Disaster victims are likely to experience tremendous psychological stress; however, the relationship between natural disasters and migraine attacks is not well investigated. METHODS: A retrospective longitudinal cohort study was conducted using the National Database of Health Insurance Claims in the hardest-hit areas of the disaster 1 year before and after the disaster. We included people between the ages of 15 and 64 years. Those who had a victim code that was certificated by a local government were assigned to the victim group, and others to the nonvictim group. For those who were not prescribed acute treatment before the disaster (i.e., group without previous acute treatment), the cumulative incidence of new prescriptions for acute treatment at 12 months of follow-up was calculated and compared between victims and nonvictims with survival analysis. RESULTS: Of 3,475,515 people aged 15 to 64 years enrolled in the study, 16,103 (0.46%) were assigned to the victim group. In the group without previous acute treatment, 111 (0.70%) of 15,933 victims and 14,626 (0.43%) of 3,431,423 nonvictims were newly prescribed acute treatment after the disaster, and new prescriptions for acute treatment were significantly more likely to occur in victims than in nonvictims (adjusted hazard ratio, 1.68; 95% CI, 1.39-2.02). CONCLUSIONS: The 2018 Japan Floods increased the number of prescriptions for acute migraine medications among victims, suggesting that acute migraine attacks occurred more frequently after a natural disaster.

BACKGROUND: Most older people with disabilities or illnesses continue to use long-term care (LTC) services for the rest of their lives. However, disasters can cause a discontinuation of LTC services, which usually means tragic outcomes of affected persons. In view of the recent progression of population aging and the increase in natural disasters, this study focuses on the impact of disasters on older people's discontinuation of LTC services, and those more risk of such discontinuation than others. However, current evidence is scarce. METHODS: We conducted a retrospective cohort study with 259,081 subjects, 2,762 of whom had been affected by disaster and 256,319 who had not been affected during the 2018 Japan Floods. The sample in the three most disaster-affected prefectures was drawn from the Long-term Care Insurance Comprehensive Database and included older people certified with care-need level. The observation period was two months before the disaster and five months after it. We calculated the hazard ratio (HR) of municipality-certified subjects affected by the disaster versus those who were not. Subgroup analyses were conducted for categories of individual-, facility- and region-associated factors. RESULTS: Affected persons were twice as likely to discontinue LTC services than those who were not affected (adjusted HR, 2.06 95% CI, 1.91-2.23). 34% of affected persons whose facilities were closed discontinued their LTC services at five months after the disaster. A subgroup analysis showed that the risk of discontinuing LTC services for affected persons compared to those who were not affected in the relatively younger subgroup (age < 80: adjusted HR, 2.55; 95% CI, 2.20-2.96 vs. age ≥ 80 : 1.91; 1.75-2.10), and the subgroup requiring a lower level of care (low: 3.16; 2.74-3.66 vs. high: 1.71; 1.50-1.96) were more likely to discontinue than the older and higher care level subgroups. CONCLUSIONS: A natural disaster has a significant effect on the older people's discontinuation of LTC services. The discontinuations are supposedly caused by affected persons' death, hospitalization, forced relocation of individuals, or the service provider's incapacity. Accordingly, it is important to recognize the risk of disasters and take measures to avoid discontinuation to protect older persons' quality of life.

BACKGROUND: Climate change has increased the frequency and severity of torrential rains and floods around the world. Estimating the costs of these disasters is one of the five global research priorities identified by WHO. The 2018 Japan Floods hit western Japan causing extensive destruction and many deaths, especially among vulnerable elderly. Such affected elderly would need long-term care due to the various health problems caused by the disaster. A Long-Term Care Insurance (LTCI) system provides care services in Japan. The aim of this study was to evaluate the effect of the 2018 Japan Floods on LTCI costs and service utilization. METHODS: The participants of this retrospective cohort study were all verified persons utilizing LTCI services in Hiroshima, Okayama and Ehime prefectures. The observation period was from 2 months before to 6 months after the disaster. We used Generalized Estimating Equations (GEEs) to examine the association between disaster status (victims or non-victims) and the monthly total costs of LTCI service (with gamma-distribution/log-link) by residential environment (home or facility). Among home residents, we also examined each service utilization (home-based service, short-stay service and facility service), using the GEEs. After the GEEs, we estimated Average Marginal Effects (AME) over all observation periods by months as the attributable disaster effect. RESULTS: The total number of participants was 279,578. There were 3024 flood victims. The disaster was associated with significantly higher total costs. The AME for home residents at 2 months after was $214 (Standard Error (SE): 12, p < 0.001), which was the highest through the observation period. Among facility residents, the AME immediately after the disaster increased by up to $850 (SE: 29, p < 0.001). The service utilization among home residents showed a different trend for each service. The AME of home-based services decreased by up to - 15.2% (SE:1.3, p < 0.001). The AME for short-stay service increased by up to 8.2% (SE: 0.9, p < 0.001) and the AME for facility service increased by up to 7.4% (SE: 0.7, p < 0.001), respectively. CONCLUSIONS: The 2018 Japan Floods caused an increase in LTCI costs and the utilization of short-stay and facility services, and a decrease in utilization of home-based services.

OBJECTIVES: Natural disasters can impair the cognitive function of older victims. However, it is unknown whether such natural disasters affect drug treatment for dementia. The aim of this study was to evaluate the effect of the 2018 Japan Floods, the second largest water-related disaster in Japan, on the prescriptions of antidementia drugs (ADD) for older people (≥65 years of age). DESIGN: Retrospective cohort study. SETTING AND PARTICIPANTS: Prescription data in Hiroshima, Okayama, and Ehime prefectures for 1 year before and after the disaster were extracted from the National Database of Health Insurance Claims. From the database, we selected 1,710,119 people age 65 years or over as the study participants. METHODS: In logistic regression models, sex- and age-adjusted odds ratios (ORs) of victims for new ADD prescriptions were calculated. Trends for the ORs before and after the disaster were evaluated using difference-in-difference models. Whether or not there was an increase in the trend for ADD prescriptions (daily dose or number of drug types) was also evaluated among continuous ADD users. RESULTS: Among 1,710,119 participants, 15,994 (0.9%) were recorded as a disaster-victims, and 112,289 (6.6%) were prescribed ADD. Among original nonusers, after the disaster, victims were more likely to start using ADD than nonvictims who had not been affected [adjusted OR = 1.33 (95% CI 1.16-1.52)]. Among continuous users, an increasing trend for ADD prescriptions was more often observed for victims than nonvictims [1.61 (1.13-2.31)]. This effect was robust even after the predisaster trend of ADD use was taken into consideration. CONCLUSIONS AND IMPLICATIONS: The disaster increased the number of users of antidementia medications. The findings suggest the need for evidence-based recommendations to address cognitive impairment among disaster victims, which is lacking in current clinical and disaster guidelines worldwide.

BACKGROUND: The July 2018 Japan Floods caused enormous damage to western Japan. Such disasters can especially impact elderly persons. Research has shown that natural disasters exacerbated a decline in cognitive function, but to date, there have been no studies examining the effects of this disaster on the elderly. The object of this study was to reveal the effect of this disaster in terms of cognitive decline among the elderly. METHODS: Study participants were certified users of the long-term care insurance (LTCI) system in Hiroshima, Okayama, and Ehime prefectures from May 2018 to June 2018. The observation period was from July 2018 to December 2018. Our primary outcome was cognitive decline after the disaster using a dementia symptomatology assessment. In addition to a crude model, a multivariate Cox proportional hazards model was used to assess the cognitive decline of victims, adjusting for age classification, gender, the level of dementia scale before the disaster occurred, residential environment, whether a participant used facilities shut down after the disaster, and population density. After we confirmed that the interaction term between victims and residential environment was statistically significant, we stratified them for the analysis. RESULTS: The total number of participants was 264,614. Victims accounted for 1.10% of the total participants (n = 2,908). For the Cox proportional hazards model, the hazard ratio of the victims was 1.18 (95% confidential interval (CI): 1.05-1.32) in the crude model and 1.12 (95% CI: 1.00-1.26) in the adjusted model. After being stratified by residential environment, the hazard ratio of home victims was 1.20 (95% CI: 1.06-1.36) and the hazard ratio of facility victims was 0.89 (95% CI: 0.67-1.17). CONCLUSIONS: This study showed that elderly living at home during the 2018 Japan Floods were at risk for cognitive decline. Medical providers, care providers, and local governments should establish a system to check on the cognitive function of elderly victims and provide necessary care support.

High-speed information and communication technology (ICT) networks stretch all over Japan. However, their utility in facilitating rural healthcare remains uncharacterized. A nationwide questionnaire survey was sent by mail to 1,018 rural clinics constructed in a public manner in municipalities throughout Japan. ICT use was classified by type, including a doctor-to-doctor manner. Only 19% of the 303 clinics surveyed (with a response rate of 30%) used ICT. Specifically, 50% used it in a doctor-to-doctor manner, while 35% used it to obtain electronic medical records. Differences in proficiency levels among ICT users were cited by 21% of the respondents as a major problem associated with ICT use. In Japan, the prevalence of ICT use for rural healthcare appeared low. We suggest a policy reform to facilitate ICT use in rural healthcare.
RESUMEN
This study aimed to examine the structure of the awareness of long-term care socialization by focusing on the younger generation's awareness in order to improve a sustainable long-term care system. A questionnaire that assessed personal attributes and awareness of long-term care socialization was administered. In total, the answers of 209 students (48.4%) were collected for factors related to the awareness of long-term care socialization extracted through exploratory factor analysis. Additionally, the responses 149 students (56.7%) were collected for the construct validity verified through confirmatory factor analysis. According to the exploratory factor analysis, awareness of long-term care socialization included 10 items and three factors: "care burden when caring for family", "feelings about leaving family care to society", and "sense of responsibility to care for family as a member of the family". The goodness-of-fit model in the confirmatory factor analysis proved the awareness of long-term care socialization scale's construct validity. The structure of the awareness of long-term care socialization included three factors: "care burden when caring for family", "sense of responsibility to care for family as a member of the family", and "feelings about leaving family care to society". This study demonstrated the scale's good reliability and validity.
RESUMEN
BACKGROUND: Japan has established comprehensive education-scholarship programs to supply physicians in rural areas. Their entrants now comprise 16% of all medical students, and graduates must work in rural areas for a designated number of years. These programs are now being adopted outside Japan, but their medium-term outcomes and inter-program differences are unknown. METHODS: A nationwide prospective cohort study of newly licensed physicians 2014-2018 (n = 2454) of the four major types of the programs-Jichi Medical University (Jichi); regional quota with scholarship; non-quota with scholarship (scholarship alone); and quota without scholarship (quota alone)-and all Japanese physicians in the same postgraduate year (n = 40,293) was conducted with follow-up workplace information from the Physician Census 2018, Ministry of Health, Labour and Welfare. In addition, annual cross-sectional survey for prefectural governments and medical schools 2014-2019 was conducted to obtain information on the results of National Physician License Examination and retention status for contractual workforce. RESULTS: Passing rate of the National Physician License Examination was highest in Jichi, followed in descending order by quota with scholarship, the other two programs, and all medical graduates. The retention rate for contractual rural service of Jichi graduates 5 years after graduation (n = 683; 98%) was higher than that of quota with scholarship (2868; 90%; P < 0.001) and scholarship alone (2220; 81% < 0.001). Relative risks of working in municipalities with the least population density quintile in Jichi, quota with scholarship, scholarship alone, and quota alone in postgraduate year 5 were 4.0 (95% CI 3.7-4.4; P < 0.001), 3.1 (2.6-3.7; < 0.001), 2.5 (2.1-3.0; < 0.001), and 2.5 (1.9-3.3; < 0.001) as compared with all Japanese physicians. There was no significant difference between each program and all physicians in the proportion of those who specialized in internal medicine or general practice in postgraduate years 3 to 5 CONCLUSIONS: Japan's education policies to produce rural physicians are effective but the degree of effectiveness varies among the programs. Policymakers and medical educators should plan their future rural workforce policies with reference to the effectiveness and variations of these programs.

ORIC ID: 0000-0002-3401-8191. It is unknown whether the interrelationship between diabetes and muscle loss is affected by ageing. Therefore, the serum creatinine levels, an indicator of muscle mass, were compared between older people with diabetes and those without diabetes, using a cross-sectional dataset from the Yuport Medical Checkup Center Study. We classified 6133 participants without kidney dysfunction into three age-groups: early-elderly (65-69 years), middle-elderly (70-74 years), and late-elderly (≥ 75 years). The association between diabetes and the lowest creatinine level, defined as less than or equal to the 25 percentile of serum creatinine, was evaluated in each age group, by calculating the odds ratio (OR) using logistic regression. Serum creatinine levels increased with ageing in the participants, and these trends were markedly observed in the non-diabetic group. Late-elderly people with diabetes were significantly more likely to have low creatinine levels than those without diabetes, with adjusted ORs 2.50 (95% CI 1.99-4.50) in men and 2.88 (95% CI 1.47-5.64) in women. Ageing modified the effect of their diabetes status towards a lower creatinine level (p for interactions between the diabetic status and age-groups were 0.01 in men and 0.05 in women, respectively). Ageing may thus accelerate the loss of muscle mass in people with diabetes.

BACKGROUND: Geographical imbalances in the health workforce, particularly the shortage of health care workers in rural areas, is an issue of social and political concern in most countries. Estimating the number of required doctors is essential for evidence-based health policy planning. In this study, we propose two methods for estimating the number of required doctors using a simple method. One is counting by unit and the other is incorporating access to medical institutions. The purpose of this study is to verify the need to incorporate access to medical institutions when estimating the number of required physicians in a region by comparing both estimation methods from the viewpoint of regional population density. METHODS: We calculated the ratio of outpatients who can access medical institutions and the number of required physicians using the travel time by car and the number of patients who can be treated per doctor per day (estimation method for the number of physicians based on the access simulation, hereinafter referred to as EAS). We compared the results of this estimation with those of a conventional method, such as the number of doctors per population (estimation method for the number of physicians based on the number of patients, hereinafter referred to as ENP) to show how important it is to incorporate the element of accessibility in such a simulation analysis. Based on the results, we discussed the applicability of the proposed method. RESULTS: ENP estimated that 38,685 outpatient primary care (PC) physicians were required and EAS estimated that 46,378 were required. There was a difference of about 8000. A comparison of the EAS-estimated number of physicians and the ENP-estimated number of physicians showed that the ENP-estimated number was small, particularly in areas with low population density. CONCLUSIONS: The results showed that it is effective to use the proposed EAS method for the estimation of PC physicians, particularly in areas with low population density. We showed that the method of allocating the number of physicians in proportion to the number of patients in a certain unit requires paying attention to the setting of the unit.
