The impact of cardiac rehabilitation for older adults with heart failure who underwent invasive cardiac treatment eligible for long-term care needs certification: A retrospective cohort study.

Background: This study aimed to assess the usefulness of cardiac rehabilitation (CR) for older adults with heart failure (HF) who need nursing care and investigate the effect of CR on cognitive function (CF) and basic activities of daily living (BADL). Methods: This was a retrospective cohort study. The study included older adults with HF eligible for long-term care insurance in fiscal year 2014 (FY2014) as the baseline and followed them up until March 2018. Patients were divided into two groups, CR (+) and CR (-), and the changes in their CF and BADL scores over time for 3 years were investigated. Results: Of the 765 patients included in the study, 36.5% performed CR. BADL scores in the CR (+) and CR (-) groups (mean (SE)) were 5.81 (0.26) vs. 5.87 (0.20) in FY2014, 5.6 (0.28) vs. 5.92 (0.21) in FY2015, 5.72 (0.31) vs. 6.15 (0.22) in FY2016, and 5.64 (0.33) vs. 6.40 (0.25) in FY2017, respectively. BADL scores worsened over time in the CR (-) group but had a trend to inhibit decline in the CR (+) group, and a significant difference was observed between both groups (p = 0.04). Multivariate analysis showed a significant difference in CR as a factor suppressing ADL decline after 1 year (adjusted odds ratios: 0.54, 95% confidence intervals: 0.36-0.82; p = 0.004). However, no significant difference in the CF scores was observed. Conclusion: CR for older adults with HF eligible for long-term care needs certification does not affect CF and may suppress ADL decline.

Real-world data on home end-of-life care for older adults with cancer: A retrospective claims data analysis.

Background: Cancer incidence is expected to increase with population aging, making the availability of places for treating patients with terminal cancer a pressing issue. However, little is known about the actual state of home end-of-life care (HEC) in Japan. Objective: The objective of this study was to examine the real-world state of HEC for older adults with cancer. Methods: The Yokohama Original Medical Database was used to identify the cohort. Data of target patients was extracted based on three criteria: age ≥65 years, malignant neoplasm diagnosis, and having a specific billing code of HEC. Multivariable linear and logistic regression models were used to evaluate the association between age groups and HEC services or outcome indexes. Results: Overall, 1323 people (554 and 769 aged < 80 and ≥ 80 years, respectively; men, 59.2%) had planned to receive HEC. The < 80 years group had more frequent emergent home visits than the ≥ 80-year group (P < 0.001), but the number of monthly home visits was similar between the two groups (P = 0.267). The rate of emergent admission was 5.9% in the ≥ 80-year group, which was higher than that in the < 80-year group (3.1%; P = 0.018). Conversely, the rates of central venous nutrition and opioid use were higher in the < 80-year group than those in the ≥ 80-year group. Conclusions: This study reported patterns of use of HEC among older adults with cancer in the terminal stage. Our findings may provide the basis for providing HEC for older adults with cancer.

Predictors of Major Adverse Cardiovascular and Cerebrovascular Events After Acute Coronary Syndromes: A Retrospective Observational Study Using YoMDB Database.

Objectives: Despite the rapid aging of the population in Japan, clinical predictors for major adverse cerebrovascular and cardiovascular events (MACCE) in patients with new onset of acute coronary syndromes (ACS) have not been well studied. This study therefore aimed to identify the predictors of MACCE in the first onset of ACS patients requiring care. Materials and Methods: Using the Yokohama Original Medical Database, we identified 3,373 patients who experienced a first onset of ACS and had certified care information from April 2014 to March 2016. The incidence proportion of MACCE from June 2014 to March 2018 was retrospectively investigated. Each patient's independence of daily living (IDL) was classified as one of three categories (reference, mild and severe). Results: Predictors of MACCE were identified using multivariate logistic regression analysis. Impaired IDL was associated with increased MACCE, with adjusted odds ratios for reference, mild and severe of 1.00, 1.35 (95% confidence intervals 1.14-1.60) and 2.12 (95% confidence intervals 1.61-2.80; P for trend < 0.001), respectively. Conclusions: This study revealed that male sex, chronic kidney disease, atrial fibrillation, high-intensity statin use, low-intensity statin use, and lower IDL (representing less independence) were the predictors of MACCE requiring care for a first onset of ACS. Further research will be required to understand the results of interventions for the identified predictors of MACCE.

Fragmentation of ambulatory care among older adults: an exhaustive database study in an ageing city in Japan.

OBJECTIVES: Continuity of care is a core dimension of primary care, and better continuity is associated with better patient outcomes. Therefore, care fragmentation can be an indicator to assess the quality of primary care, especially in countries without formal gatekeeping system, such as Japan. Thus, this study aimed to describe care fragmentation among older adults in an ageing city in Japan. DESIGN: Cross-sectional study. SETTING: The most populated basic municipality in Japan. PARTICIPANTS: Older adults aged 75 years and older. INTERVENTIONS: This study used a health claims database, including older adults who visited medical facilities at least four times a year in an urban city in Japan. The Fragmentation of Care Index (FCI) was used as an indicator of fragmentation. The FCI was developed from the Continuity of Care Index and is based on the total number of visits, different institutions visited and proportion of visits to each institution. We employed Tobit regression analysis to examine the association between the FCI and age, sex, type of insurance and most frequently visited facility. RESULTS: The total number of participants was 413 600. The median age of the study population was 81 years, and 41.6% were men. The study population visited an average of 3.42 clinics/hospitals, and the maximum number of visited institutions was 20. The proportion of patients with FCI >0 was 85.0%, with a mean of 0.583. Multivariable analysis showed that patients receiving public assistance had a lower FCI compared with patients not receiving public assistance, with a coefficient of 0.137. CONCLUSIONS: To our knowledge, this is the first study to demonstrate care fragmentation in Japan. Over 80% of the participants visited two or more medical facilities, and their mean FCI was 0.583. The FCI could be a basic indicator for assessing the quality of primary care.

Ecology of medical care for 90+ individuals: An exhaustive cross-sectional survey in an ageing city.

AIM: Urbanization and ageing are worldwide issues for healthcare providers. In particular, older adults aged 90 years and older have increased cognitive impairment and lower daily functioning than younger adults. However, the healthcare use of the oldest old remains unclear. This study aimed to describe the healthcare use of the oldest old compared with younger older adults in a city using the ecology of medical care model. METHODS: We conducted a cross-sectional study. This study targeted all residents aged 75 years and older registered in a city in Japan for one year. We described healthcare use per 1000 inhabitants over a 1-month period and included: outpatient visits, emergency department visits, hospitalizations, home visits, home care services, and facility services. We also compared healthcare use among older adults aged 75-89 years and 90 years and older. RESULTS: We described the healthcare use of 454 366 (male/female: 186 177/268 189) older adults. The numbers of persons per 1000 residents who used healthcare resources at least once in 1 month (75-89 years/90 years and older) were: outpatient clinic visits, 622/570; hospital outpatient visits, 300/263; advanced treatment hospital outpatient visits, 16/6; emergency department visits, 10/27; hospitalizations, 45/96; advanced treatment hospital hospitalizations, 2/1; planned home visits, 36/228; urgent home visits, 6/38; home care services, 173/533; and facility services, 32/178. CONCLUSIONS: The results revealed that older adults over 90 years had more hospitalizations, emergency department visits and home visits, and used facility/home care services more compared with older adults aged 75-89 years. The results provide a useful benchmark for healthcare use estimation. Geriatr Gerontol Int 2022; 22: 483-489.
