Medical researchers' perceptions regarding research evaluation: a web-based survey in Japan.

OBJECTIVES: Japanese medical academia continues to depend on quantitative indicators, contrary to the general trend in research evaluation. To understand this situation better and facilitate discussion, this study aimed to examine how Japanese medical researchers perceive quantitative indicators and qualitative factors of research evaluation and their differences by the researchers' characteristics. DESIGN: We employed a web-based cross-sectional survey and distributed the self-administered questionnaire to academic society members via the Japanese Association of Medical Sciences. PARTICIPANTS: We received 3139 valid responses representing Japanese medical researchers in any medical research field (basic, clinical and social medicine). OUTCOMES: The subjective importance of quantitative indicators and qualitative factors in evaluating researchers (eg, the journal impact factor (IF) or the originality of the research topic) was assessed on a four-point scale, with 1 indicating 'especially important' and 4 indicating 'not important'. The attitude towards various opinions in quantitative and qualitative research evaluation (eg, the possibility of research misconduct or susceptibility to unconscious bias) was also evaluated on a four-point scale, ranging from 1, 'strongly agree', to 4, 'completely disagree'. RESULTS: Notably, 67.4% of the medical researchers, particularly men, younger and basic medicine researchers, responded that the journal IF was important in researcher evaluation. Most researchers (88.8%) agreed that some important studies do not get properly evaluated in research evaluation using quantitative indicators. The respondents perceived quantitative indicators as possibly leading to misconduct, especially in basic medicine (strongly agree-basic, 22.7%; clinical, 11.7%; and social, 16.1%). According to the research fields, researchers consider different qualitative factors, such as the originality of the research topic (especially important-basic, 46.2%; social, 39.1%; and clinical, 32.0%) and the contribution to solving clinical and social problems (especially important-basic, 30.4%; clinical, 41.0%; and social, 52.0%), as important. Older researchers tended to believe that qualitative research evaluation was unaffected by unconscious bias. CONCLUSION: Despite recommendations from the Declaration on Research Assessment and the Leiden Manifesto to de-emphasise quantitative indicators, this study found that Japanese medical researchers have actually tended to prioritise the journal IF and other quantitative indicators based on English-language publications in their research evaluation. Therefore, constantly reviewing the research evaluation methods while respecting the viewpoints of researchers from different research fields, generations and genders is crucial.

Relationship between health checkups and cancer screenings of wives and health checkups of their husbands: A cross-sectional study in Japan.

Objectives: This study investigated the relationship between health checkups, cervical cancer screenings, and breast cancer screenings (collectively referred to as wellness examinations) of wives and health checkups of their husbands. We aimed to develop strategies to encourage wellness examinations among married individuals in Japan. Methods: This study used the 2019 Comprehensive Survey of Living Conditions, focusing on married couples aged 40-64. We analyzed the percentage of wives undergoing wellness examinations, grouped based on whether their husbands had undergone health checkups. Subsequently, multivariable modified Poisson regression analysis was performed considering sociodemographic and health-related factors. All analyses considered medical insurance of wives because wellness examination methods varied depending on medical insurance type. Results: The sample comprised 40,560 couples undergoing health checkups, 39,870 undergoing cervical cancer screening, and 39,895 undergoing breast cancer screening. Regardless of the medical insurance type of the wife, a significant positive association was observed between the wellness examination of wives and the health checkup of husbands across all age groups. After adjusting for covariates, prevalence ratios (95% confidence intervals) for wives whose husbands underwent health checkups were 2.24 (2.09-2.40) for national health insurance, 1.18 (1.16-1.21) for employee insurance (employee), and 1.53 (1.44-1.63) for employee insurance (family) for health checkups. Similar trends were observed in cervical and breast cancer screening. Conclusions: Wellness examinations of wives were associated with those of their husbands, suggesting that couples often share similar health-seeking behaviors. Hence, targeted interventions are important for couples who do not undergo wellness examinations.

Implementation rate of diabetic self-management education and support for Japanese people with diabetes using the National Database.

People with diabetes are encouraged to receive diabetes self-management education and support (DSMES) appropriately. However, in Japan, the implementation rates of DSMES are not known. DSMES implementation rates were calculated using the National Database of claims data, which included nearly all insurance-covered medical procedures. The study enrolled participants who received regular antidiabetic medications between April 2017 and March 2018. The implementation rates of DSMES-related care were calculated by characteristics, visiting medical facilities and prefectures. In 4,465,513 participants receiving antidiabetic medications (men, 57.8%; insulin use, 14.1%), nutrition guidance (5.6%) was the most frequently provided care type. Insulin users and participants visiting Japan Diabetes Society-certified and large medical institutions had higher implementation rates of nutrition guidance. DSMES-related care might not be provided adequately for Japanese people with diabetes. Further studies are needed to develop an optimal diabetes care system.

Literature Review of Studies Using the National Database of the Health Insurance Claims of Japan (NDB): Limitations and Strategies in Using the NDB for Research.

The use of the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB) for research has increased over time. Researchers need to understand the characteristics of the data to generate quality-assured evidence from the NDB. In this review, we mapped and characterized the limitations and related strategies using the NDB for research based on the descriptions of published NDB studies. To find studies that used Japanese healthcare claims data, we searched MEDLINE, EMBASE, and Ichushi-Web up to June 2023. Additionally, we hand-searched the NDB data publication list from the Ministry of Health, Labour and Welfare (2017-2023). We abstracted data based on the NDB data type, research themes, age of the study sample or population, targeted disease, and the limitations and strategies in the NDB studies. Ultimately, 267 studies were included. Overall, the most common research theme was describing and estimating the prescriptions and treatment patterns (125 studies, 46.8%). There was a variation in the frequency of themes according to the type of NDB data. We identified the following categories of limitations: (1) lack of information on confounders/covariates, outcomes, and other clinical content, (2) limitations regarding patients not included in the NDB, (3) misclassification of data, (4) lack of unique identifiers and register of beneficiaries, and (5) others. Although the included studies noted several limitations of using the NDB for research, they also provided some strategies to address them. Organizing the limitations of NDB in research and the related strategies across research fields can help support high-quality NDB studies.

Long-term outcomes of stereotactic radiosurgery for intracranial schwannoma in neurofibromatosis type 2: a genetic analysis perspective.

PURPOSE: Neurofibromatosis type 2 (NF2) is intractable because of multiple tumors involving the nervous system and is clinically diverse and genotype-dependent. Stereotactic radiosurgery (SRS) for NF2-associated schwannomas remains controversial. We aimed to investigate the association between radiosurgical outcomes and mutation types in NF2-associated schwannomas. METHODS: This single-institute retrospective study included consecutive NF2 patients with intracranial schwannomas treated with SRS. The patients' types of germline mutations ("Truncating," "Large deletion," "Splice site," "Missense," and "Mosaic") and Halliday's genetic severity scores were examined, and the associations with progression-free rate (PFR) and overall survival (OS) were analyzed. RESULTS: The study enrolled 14 patients with NF2 with 22 associated intracranial schwannomas (median follow-up, 102 months).　The PFRs in the entire cohort were 95% at 5 years and 90% at 10-20 years. The PFRs tended to be worse in patients with truncating mutation exons 2-13 than in those with other mutation types (91% at 5 years and 82% at 10-20 years vs. 100% at 10-20 years, P = 0.140). The OSs were 89% for patients aged 40 years and 74% for those aged 60 years in the entire cohort and significantly lower in genetic severity group 3 than in the other groups (100% vs. 50% for those aged 35 years; P = 0.016). CONCLUSION: SRS achieved excellent PFR for NF2-associated intracranial schwannomas in the mild (group 2A) and moderate (group 2B) groups. SRS necessitates careful consideration for the severe group (group 3), especially in cases with NF2 truncating mutation exons 2-13.

Association between spatial access and hospitalization for ambulatory care sensitive conditions: A retrospective cohort study using claims data.

Background: Hospitalization for ambulatory care sensitive conditions (ACSCs) is potentially preventable with timely and effective primary care but may increase owing to poor access. Spatial access inequalities exist between Japan and other countries. This retrospective cohort study examined the association between admission for ACSC and spatial accessibility to primary care. Methods: We used claims data and spatial data of 50-74 years-old beneficiaries of the National Health Insurance program in a large city in Japan from April 2013-March 2014 and followed them until March 2015. We used a multilevel Poisson regression model to assess the association between the number of ACSC admissions, the distance to the nearest clinic, and the number of physicians in a given area, adjusting for age, gender, comorbidities, number of visits, and household income. Results: Among 126,666 eligible beneficiaries (mean age 65.8 years, 54% were women), 1,793 (1.4%) were hospitalized for ACSCs. The ACSC admission rate was significantly higher in those with a distance to the nearest clinic of >1 km than in those with <0.3 km (incident rate ratio [IRR] 1.32, 95% confidence interval [CI] 1.03-1.69). In the stratified analyses, a longer distance to the nearest clinic was associated with higher ACSC admission rates among women (≥0.3 km and <0.5 km: IRR 1.48, 95% CI 1.01-2.17; ≥0.5 km and <1 km: IRR 1.74, 95% CI 1.19-2.56; >1 km: IRR 1.98, 95% CI 1.29-3.03, respectively) and those aged ≥65 years (≥0.3 km and <0.5 km: IRR 1.38, 95% CI 1.07-1.79; ≥0.5 km and <1 km: IRR 1.38, 95% CI 1.06-1.80; >1 km: IRR 1.48, 95% CI 1.10-1.98). Conclusion: Unfavorable spatial access was associated with ACSC admissions, particularly among women and older adults.

Barriers to and facilitators of advance care planning implementation for medical staff after the COVID-19 pandemic: an overview of reviews.

OBJECTIVE: The COVID-19 pandemic has impacted the capacity for advance care planning (ACP) among patients, families and healthcare teams. We sought to identify and review the barriers to and facilitators of ACP implementation for medical staff in different settings (eg, hospitals, outpatient palliative care, nursing and care homes) during the pandemic. DESIGN: This study employed an overview of reviews design. We searched the MEDLINE, CENTRAL, Web of Science and Embase databases for studies published between 8 December 2019 and 30 July 2023. We used AMSTAR 2 to assess the risk of bias. RESULTS: We included seven reviews. Common barriers to ACP implementation included visitation restrictions, limited resources and personnel and a lack of coordination among healthcare professionals. In care and nursing homes, barriers included a dearth of palliative care physicians and the psychological burden on facility staff. Using telemedicine for information sharing was a common facilitator across settings. In hospitals, facilitators included short-term training in palliative care and palliative care physicians joining the acute care team. In care and nursing homes, facilitators included ACP education and emotional support for staff. CONCLUSIONS: Visitation restrictions and limited resources during the pandemic posed obstacles; however, the implementation of ACP was further hindered by insufficient staff education on ACP in hospitals and facilities, as well as a scarcity of information sharing at the community level. These pre-existing issues were magnified by the pandemic, drawing attention to their significance. Short-term staff training programmes and immediate information sharing could better enable ACP. PROSPERO REGISTRATION NUMBER: CRD42022351362.

Facility staffing associated with potentially avoidable hospitalizations in nursing home residents in Japan: a retrospective cohort study.

BACKGROUND: Wide variations in facility staffing may lead to differences in care, and consequently, adverse outcomes such as hospitalizations. However, few studies focused on types of occupations. Therefore, we aimed to examine the association between a wide variety of facility staffing and potentially avoidable hospitalizations of nursing home residents in Japan. METHODS: In this retrospective cohort study using long-term care and medical insurance claims data in Ibaraki Prefecture from April 2018 to March 2019, we identified individuals aged 65 years and above who were newly admitted to nursing homes. In addition, facility characteristic data were obtained from the long-term care insurance service disclosure system. Subsequently, we conducted a multivariable Cox regression analysis and evaluated the association between facility staffing and potentially avoidable hospitalizations. RESULTS: A total of 2909 residents from 235 nursing homes were included. The cumulative incidence of potentially avoidable hospitalizations at 180 days was 14.2% (95% confidence interval [CI] 12.7-15.8). Facilities with full-time physicians (adjusted hazard ratio [HR]: 0.59, 95% CI: 0.37-0.94) and a higher number of dietitians (HR: 0.72, 95% CI: 0.54-0.97) were significantly associated with a lower likelihood of potentially avoidable hospitalizations. In contrast, having nurses or trained caregivers during the night shift (HR: 1.72, 95% CI: 1.25-2.36) and a higher number of care managers (HR: 1.37, 95% CI: 1.03-1.83) were significantly associated with a high probability of potentially avoidable hospitalizations. CONCLUSIONS: We revealed that variations in facility staffing were associated with potentially avoidable hospitalizations. The results suggest that optimal allocation of human resources, such as dietitians and physicians, may be essential to reduce potentially avoidable hospitalizations. To provide appropriate care to nursing home residents, it is necessary to establish a system to effectively allocate limited resources. Further research is warranted on the causal relationship between staff allocation and unnecessary hospitalizations, considering the confounding factors.

Studies of Health Insurance Claims Data in Japan: A Scoping Review.

Background: Health insurance claims data are used in various research fields; however, an overview on how they are used in healthcare research is scarce in Japan. Therefore, we conducted a scoping review to systematically map the relevant studies using Japanese claims data. Methods: MEDLINE, EMBASE, and Ichushi-Web were searched up to April 2021 for studies using Japanese healthcare claims data. We abstracted the data on study characteristics and summarized target diseases and research themes by the types of claims database. Moreover, we described the results of studies that aimed to compare health insurance claims data with other data sources narratively. Results: A total of 1,493 studies were included. Overall, the most common disease classifications were "Diseases of the circulatory system" (18.8%, n = 281), "Endocrine, nutritional, and metabolic diseases" (11.5%, n = 171; mostly diabetes), and "Neoplasms" (10.9%, n = 162), and the most common research themes were "medical treatment status" (30.0%, n = 448), "intervention effect" (29.9%, n = 447), and "clinical epidemiology, course of diseases" (27.9%, n = 417). Frequent diseases and themes varied by type of claims databases. A total of 19 studies aimed to assess the validity of the claims-based definition, and 21 aimed to compare the results of claims data with other data sources. Most studies that assessed the validity of claims data compared to medical records were hospital-based, with a small number of institutions. Conclusions: Claims data are used in various research areas and will increasingly provide important evidence for healthcare policy in Japan. It is important to use previous claims database studies and share information on methodology among researchers, including validation studies, while informing policymakers about the applicability of claims data for healthcare planning and management.

Factors associated with non-participation in breast cancer screening: analysis of the 2016 and 2019 comprehensive survey of living conditions in Japan.

BACKGROUND: The participation rate for breast cancer screening remains to be suboptimal in Japan. Therefore, it is important to identify factors associated with non-participation and identify people at high risk for non-participation. METHODS: We carried out a cross-sectional study using the data of women aged 40-74 years from the 2016 and 2019 Comprehensive Survey of Living Conditions. We selected candidate predictor variables from the survey sheets and conducted a multivariable logistic regression for non-participation in breast cancer screening for the past 2 years. In addition, using data from 2016, we created an integer risk score for non-participation and tested its predictive performance in 2019. RESULTS: The proportion of participants in breast cancer screening in 2016 and 2019 were 46.7% (50,177/107,513) and 48.7% (49,498/101,716), respectively. In multivariable logistic regression analysis, age over 50 years, single/divorced/widowed, lower education level, lower household expenditure, being insured for National Health Insurance, employed to small/middle scale company, non-regularly employed, current smoker, never/quit drinking or middle/high-risk drinking, lower self-rated health status, higher Kessler Psychological Distress Scale score, non-participation in the annual health checkups for diseases other than cancer, not constantly visiting hospitals/clinics showed a positive association with non-participation. The 9-item risk score (age, marital status, education, health insurance plan, employment, smoking, drinking, non-participation in the annual health checkups for diseases other than cancer, and not constantly visiting hospitals/clinics) and 3-item risk score (age, health insurance plan, non-participation in the annual health checkups for diseases other than cancer) showed the area under the receiver operating characteristic curve of 0.744 and 0.720, respectively. CONCLUSION: We identified factors associated with non-participation in breast cancer screening. The simple risk score would be useful for public health sectors to identify people at risk for non-participation.

Different incidences of diabetic retinopathy requiring treatment since diagnosis according to the course of diabetes diagnosis: a retrospective cohort study.

We aimed to estimate the cumulative incidence of treatment-requiring diabetic retinopathy since clinical diagnosis of diabetes based on the course of diagnosis in a retrospective cohort study using Japan's medical claims and health checkup data (JMDC Claims Database; 2009-2020). We included patients whose diabetes was first diagnosed at medical facilities (hospitals/clinics). We grouped them by health checkup participation before diagnosis, health checkup results, and antidiabetic medication promptly after the diagnosis. The incidence of treatment-requiring diabetic retinopathy (laser photocoagulation, intraocular injection, or vitrectomy) was compared among the groups. Of 126,696 patients, those who started an antidiabetic medication promptly after diabetes diagnosis without a recent health checkup faced the highest risk of treatment-requiring diabetic retinopathy (1-/5-year cumulative incidence: 3.1%/6.0%). This increased risk was consistently observed across various analyses, including the Cox proportional hazard model, sensitivity analysis restricting to those with an eye examination, and sensitivity analysis using vitrectomy as the outcome. Among patients with HbA1c ≥ 6.5% at recent health checkups, those who promptly started an antidiabetic medication had a higher risk (1.4%/3.8%) than those who did not (0.7%/2.7%). Taking the information about the course of diabetes diagnosis is important to manage risk stratification for diabetic retinopathy appropriately.

Patient referral flow between physician and ophthalmologist visits for diabetic retinopathy screening among Japanese patients with diabetes: A retrospective cross-sectional cohort study using the National Database.

AIMS/INTRODUCTION: Regular screening for diabetic retinopathy is essential. This study aimed to show the process and current situation of diabetic retinopathy screening prescribed by physicians (internists) and ophthalmologists for Japanese patients with diabetes. MATERIALS AND METHODS: This retrospective cohort study used data from the Japanese National Database of Insurance Claims between April 2016 and March 2018. Ophthalmology visits and fundus examinations are defined using specific medical procedure codes. The proportion of ophthalmology visits for patients with diabetic medication and for fundus examination among those who visited ophthalmologists was calculated in the fiscal year 2017. A modified Poisson regression analysis was carried out to identify factors associated with retinopathy screening. Similarly, quality indicators by prefectures were also calculated. RESULTS: Among 4,408,585 patients receiving diabetic medications (57.8% men, 14.1% insulin use), 47.4% visited the ophthalmology department and 96.9% of those underwent fundus examination. Regression analysis showed that female sex, older age, insulin use, medical facilities with Japan Diabetes Society certification and large medical facilities were predictors of fundus examination. By prefecture, the ophthalmology consultation rate and the fundus examination ranged 38.5-51.0% and 92.1-98.7%, respectively. CONCLUSIONS: Less than half of the patients who were prescribed antidiabetic medication by their physicians visited an ophthalmologist. However, most of the patients who visited an ophthalmologist had a fundus examination carried out. A similar tendency was noted for each prefecture. It is essential to reaffirm the necessity of recommending ophthalmologic examinations to physicians and healthcare professionals who care for patients with diabetes.

Impact of COVID-19 pandemic on behavioral changes and glycemic control and a survey of telemedicine in patients with diabetes: A multicenter retrospective observational study.

AIMS/INTRODUCTION: To investigate whether the COVID-19 pandemic affected behavioral changes and glycemic control in patients with diabetes and to conduct a survey of telemedicine during the pandemic. MATERIALS AND METHODS: In this retrospective study, a total of 2,348 patients were included from 15 medical facilities. Patients were surveyed about their lifestyle changes and attitudes toward telemedicine. Hemoglobin A1c (HbA1c) levels were compared among before (from June 1 to August 31, 2019) and in the first (from June 1 to August 31, 2020) and in the second (from June 1 to August 31, 2021) year of the pandemic. A survey of physician attitudes toward telemedicine was also conducted. RESULTS: The HbA1c levels were comparable between 2019 (7.27 ± 0.97%), 2020 (7.28 ± 0.92%), and 2021 (7.25 ± 0.94%) without statistical difference between each of those 3 years. Prescriptions for diabetes medications increased during the period. The frequency of eating out was drastically reduced (51.7% in 2019; 30.1% in 2020), and physical activity decreased during the pandemic (48.1% in 2019; 41.4% in 2020; 43.3% in 2021). Both patients and physicians cited increased convenience and reduced risk of infection as their expectations for telemedicine, while the lack of physician-patient interaction and the impossibility of consultation and examination were cited as sources of concern. CONCLUSIONS: Our data suggest that glycemic control did not deteriorate during the COVID-19 pandemic with appropriate intensification of diabetes treatment in patients with diabetes who continued to attend specialized diabetes care facilities, and that patients and physicians shared the same expectations and concerns about telemedicine.

Hospital-Level Variation in Cardiac Rehabilitation After Myocardial Infarction in Japan During Fiscal Years 2014-2015 Using the National Database.

Background: Cardiac rehabilitation (CR) is an evidence-based medical service for patients with acute myocardial infarction (AMI); however, its implementation is inadequate. We investigated the provision status and equality of CR by hospitals in Japan using a comprehensive nationwide claims database. Methods and Results: We analyzed data from the National Database of Health Insurance Claims and Specific Health Checkups in Japan for the period April 2014-March 2016. We identified patients aged ≥20 years with postintervention AMI. We calculated hospital-level proportions of inpatient and outpatient CR participation. The equality of hospital-level proportions of inpatient and outpatient CR participation was evaluated using the Gini coefficient. We included 35,298 patients from 813 hospitals for the analysis of inpatients and 33,328 patients from 799 hospitals for the analysis of outpatients. The median hospital-level proportions of inpatient and outpatient CR participation were 73.3% and 1.8%, respectively. The distribution of inpatient CR participation was bimodal; the Gini coefficients of inpatient and outpatient CR participation were 0.37 and 0.73, respectively. Although there were statistically significant differences in the hospital-level proportion of CR participation for several hospital factors, CR certification status for reimbursement was the only visually evident factor affecting the distribution of CR participation. Conclusions: The distributions of inpatient and outpatient CR participation by hospitals were suboptimal. Further research is warranted to determine future strategies.

Japanese Local Governments' Dissemination Activities for Advance Care Planning: A Descriptive Analysis of a Nationwide Survey during the COVID-19 Pandemic.

This study aims to compare the awareness-raising activities between municipalities with and without focused anti-infection measures during the 2019 coronavirus disease (COVID-19) pandemic. Descriptive analysis was conducted using a nationwide self-administered questionnaire survey on municipalities' activities for residents and for healthcare providers and care workers (HCPs) in October 2022 in Japan. This study included 433 municipalities that had conducted awareness-raising activities before 2019 Fiscal Year. Workshops for residents were conducted in 85.2% of the municipalities, and they were more likely to be conducted in areas with focused anti-infection measures than those without measures (86.8% vs. 75.4%). Additionally, 85.9% of the municipalities were impacted by the pandemic; 50.1% canceled workshops, while 26.0% switched to a web-based style. Activities for HCPs were conducted in 55.2-63.7% of the municipalities, and they were more likely to be conducted in areas with focused anti-infection measures. A total of 50.6-62.1% of the municipalities changed their workshops for HCPs to a web-based style. Comparisons between areas with and without focused anti-infection measures indicated that the percentages of those impacted for all activities were not significantly different. In conclusion, awareness-raising activities in municipalities were conducted with new methods during the COVID-19 pandemic. Using information technology is essential to further promote such activities for residents.

Association between types of home healthcare and emergency house calls, hospitalization, and end-of-life care in Japan.

BACKGROUND: To meet the increasing demand for home healthcare in Japan, as part of the national healthcare system, home care support clinics/hospitals (HCSCs) and enhanced HCSCs were introduced in 2006 and 2012 respectively. This study aimed to evaluate whether HCSCs has succeeded in providing 24-h home care services through the end of life. METHODS: A retrospective cohort study was conducted using the national database in Japan. Participants were ≥ 65 years of age, had newly started regular home visits between July 2014 and September 2015, and used general clinics, conventional HCSCs, or enhanced HCSCs. Each patient was followed up for 6 months after the first visit. The outcome measures were (i) emergency house call(s), (ii) hospitalization(s), and (iii) end-of-life care defined as in-home death. Multivariable logistic regression analyses were performed for statistical analysis. RESULTS: The analysis included 160,674 patients, including 13,477, 64,616, and 82,581 patients receiving regular home visits by general clinics, conventional HCSCs, and enhanced HCSCs respectively. Compared to general clinics, the use of conventional and enhanced HCSCs was associated with an increased likelihood of emergency house calls (adjusted odds ratio [aOR] and 95% confidence intervals [CIs] of 1.62 [1.56-1.69] and 1.86 [1.79-1.93], respectively) and a decreased likelihood of hospitalizations (aOR [95% CIs] of 0.86 [0.82-0.90] and 0.88 [0.84-0.92] respectively). Among 39,082 patients who died during the follow-up period, conventional and enhanced HCSCs had more in-home deaths (aOR [95% CIs] of 1.46 [1.33-1.59] and 1.60 [1.46-1.74], respectively) compared to general clinics. CONCLUSIONS: HCSCs (especially enhanced HCSCs) provided more emergency house calls, reduced hospitalization, and enabled expected deaths at home, suggesting that further promotion of HCSCs (especially enhanced HSCSs) would be advantageous.

The Effect of Business Operating Systems on Nursing Home Termination.

Objectives: Nursing home terminations have increased worldwide due to rising costs, staffing shortages, and the coronavirus disease pandemic. However, little is known about the impact that business operating systems have on nursing home termination. Methods: This study used the National Long-term Care database, which comprised 7,842 operating nursing homes in January 2018. Nursing home termination was identified when nursing homes discontinued provision of long-term care services to all residents between January 2018 and December 2020. Business operating systems that were reimbursed by the LTC insurance system were the exposure of interest. The logistic regression model for nursing home termination included a series of organizational, internal, and external factors as covariates. Results: From 2018 to 2020, 83 (1.1%) nursing homes were terminated. The proportion of reimbursed nursing homes varied greatly depending on the type of business operating systems. Implementing physical function training and improving working conditions were significantly associated with a lower risk of nursing home termination. Conclusion: Financial incentives to several business operating systems are an effective way to build a sustainable environment for nursing homes to continue to exist.

Preferred Place of End-of-Life Care Based on Clinical Scenario: A Cross-Sectional Study of a General Japanese Population.

In Japan, which has an aging society with many deaths, it is important that people discuss preferred place for end-of-life care in advance. This study aims to investigate whether the preferred place of end-of-life care differs by the assumed clinical scenario. This clinical scenario-based survey used data from a nationwide survey conducted in Japan in December 2017. Participants aged 20 years and older were randomly selected from the general population. The survey contained questions based on three scenarios: cancer, end-stage heart disease, and dementia. For each scenario, respondents were asked to choose the preferred place of end-of-life care among three options: home, nursing home, and medical facility. Eight hundred eighty-nine individuals participated in this study (effective response rate: 14.8%). The proportions of respondents choosing home, nursing home, and medical facility for the cancer scenario were 49.6%, 10.9%, and 39.5%, respectively; for the end-stage heart disease scenario, 30.5%, 18.9%, and 50.6%; and for the dementia scenario, 15.2%, 54.5%, and 30.3% (p < 0.0001, chi-square test). The preferred place of end-of-life care differed by the assumed clinical scenario. In clinical practice, concrete information about diseases and their status should be provided during discussions about preferred place for end-of-life care to reveal people's preferences more accurately.

The Effect of Home Care Support Clinics on Hospital Readmission in Heart Failure Patients in Japan.

BACKGROUND: Heart failure is common and is associated with high rates of hospitalization. Home care support clinics/hospitals (HCSCs) and enhanced HCSCs were introduced in Japan in 2006 and 2012, respectively. OBJECTIVE: This study aimed to examine the effect of post-discharge care by conventional or enhanced HCSCs on readmission, compared with general clinics. DESIGN: Retrospective cohort study using the Japanese nationwide health insurance claims database. PARTICIPANTS: Participants were ≥65 years of age, admitted for heart failure and discharged between July 2014 and August 2015 and received a home visit within a month following the discharge (n=12,393). MAIN MEASURES: The exposure was the type of medical facility that provides post-discharge home healthcare: general clinics, conventional HCSCs, and enhanced HCSCs. The primary outcome was all-cause readmission for 6 months after the first visit; the incidence of emergency house calls was a secondary outcome. We used a competing risk regression using the Fine and Gray method, in which death was regarded as a competing event. KEY RESULTS: At 6 months, readmissions were lower in conventional (38%) or enhanced HCSCs (38%) than general clinics (43%). The adjusted subdistribution hazard ratio (sHR) of readmission was 0.87 (95% CI: 0.78-0.96) for conventional and 0.86 (0.78-0.96) for enhanced HCSCs. Emergency house calls increased with conventional (sHR: 1.77, 95% CI:1.57-2.00) and enhanced HCSCs (sHR: 1.93, 95% CI: 1.71-2.17). CONCLUSIONS: Older Japanese patients with heart failure receiving post-discharge home healthcare by conventional or enhanced HCSCs had lower readmission rates, possibly due to compensation with more emergency house calls. Conventional and enhanced HCSCs may be effective in reducing the risk of rehospitalization. Further studies are necessary to confirm the medical functions performed by HCSCs.
