Background The occurrence of multimorbidity (i.e., the coexistence of multiple chronic diseases) increases with age in older adults and is a growing concern worldwide. Multimorbidity has been reported to be a driving factor in the increase of medical expenditures in OECD countries. However, to the best of our knowledge, there is no published research that has examined the associations between multimorbidity and either long-term care (LTC) expenditure or the sum of medical and LTC expenditures worldwide. We, therefore, aimed to examine the associations of multimorbidity with the sum of medical and LTC expenditures for older adults in Japan. Methods Medical insurance claims data for adults ≥75 years were merged with LTC insurance claims data from Kashiwa city, a suburb in the Tokyo metropolitan area, for the period between April 2012 and September 2013 to obtain an estimate of medical and LTC expenditures. We also calculated the 2011 updated and reweighted version of the Charlson Comorbidity Index (CCI) scores. Then, we performed multiple generalized linear regressions to examine the associations of CCI scores (0, 1, 2, 3, 4, or ≥ 5) with the sum of annual medical and LTC expenditures, adjusting for age, sex, and household income level. Results The mean sum of annual medical and LTC expenditures was ¥1,086,000 (US$12,340; n = 30,042). Medical and LTC expenditures accounted for 66 and 34% of the sum, respectively. Every increase in one unit of the CCI scores was associated with a ¥257,000 (US$2920); 95% Confidence Interval: ¥242,000, 271,000 (US$2750, 3080) increase in the sum of the expenditures ( p < 0.001; n = 29,915). Conclusions Using a merged medical and LTC claims dataset, we found that greater CCI scores were associated with a higher sum of annual medical and LTC expenditures for older adults. To the best of our knowledge, this is the first study to examine the associations of multimorbidity with LTC expenditures or the sum of medical and LTC expenditures worldwide. Our study indicated that the economic burden on society caused by multimorbidity could be better evaluated by the sum of medical and LTC expenditures, rather than medical expenditures alone.

During the COVID-19 pandemic, social interactions were restricted, including community services for disabled older adults. This study aimed to describe the change of use in community services related to long-term care insurance (LTCI) during the pandemic in Japan. A retrospective descriptive study was conducted using data collected via a cloud-based management support platform for older adult care provider “Kaipoke”, by a private-sector company “SMS Co., Ltd.”, in which care-managers of LTCI manage their office work. Data collection occurred from July 2019 to June 2020. Study subjects were LTCI service users aged 65 years and above. Subjects were living at home. We examined changes in the number of users of LTCI services before and after the COVID-19 pandemic began, using an interrupted time-series analysis. Results indicated that the use of outpatient services was reduced; however, home-visit services were maintained. The decrease in use was significant in the seven prefectures where the infection initially spread. There are concerns that older adults or surrounding caregivers can be affected by such changes in LTC service use. It is therefore necessary to implement sustainable measures from a long-term perspective and investigate their influence as part of future studies.

Aim: To determine the resident and facility characteristics associated with residents' care-need level deterioration in long-term care welfare facilities in Japan.Methods: A nationally representative sample of 358 886 residents who lived in 3774 long-term care welfare facilities for at least 1 year from October 2012 was obtained from long-term care insurance claims data. Facility characteristics were linked with a survey of institutions and establishments for long-term care in 2012. We used a multilevel logistic regression according to the inclusion and exclusion of lost to follow-up to define the resident and facility characteristics associated with resident care-need level deteriorations (lost to follow-up: the majority were hospitalized residents or had died; were treated as deterioration in the including loss to follow-up model).Results: Adjusting for the covariates, at the resident level, older age and lower care-need level at baseline were more likely to show deterioration in the care-need level. At the facility level, metropolitan facilities, unit model (all private room settings) and mixed-model facilities (partly private room settings) were less likely to experience careneed level deterioration. A higher proportion of registered nurses among all nurses was negatively related to careneed level deterioration only in the model including lost to follow-up. A higher proportion of registered dietitians among all dietitians and the facilities in business for fewer years were negatively associated with care-need level deterioration only in the model excluding lost to follow-up. Conclusions:The present study could help identify residents who are at risk of care-need level deterioration, and could contribute to improvements in provider quality performance and enhance competence in the market.

This is the first study to estimate healthcare and long-term care expenditures post-hip fracture using claims data in Japan. Further studies are needed that include healthcare claims data at both DPC/PDPS and non-DPC/PDPS hospitals to capture the lifelong course of long-term care required post-hip fracture.
