Does Dialysis Therapy Cause Cognitive Impairment in Older Adults? A Propensity Score Matching Retrospective Study From a Japanese Long-Term Care Insurance Certification Survey.

This study explored the longitudinal connection between dialysis therapy in older adults and the incidence of cognitive impairment, and trends of general abilities. We conducted a retrospective propensity score matching (PSM) analysis of data from the care-needs certification survey in City A, Japan, spanning 2017 to 2021. Our sample comprised 11 443 initially cognitively intact older adults from the baseline year 2017.

Risk factors for nursing home admission among older adults: Analysis of basic movements and activities of daily living.

This retrospective study aimed to clarify the risk of older adults' nursing home placement in terms of basic movements and activities of daily living (ADLs) by analyzing data from a long-term care insurance certification survey in 2016‒2018 in City A. Of the 21,520 people certified as needing care, 16,865 could be followed up until 2018. Data on sex, age, household structure, and level of care required were obtained.

Older Adults Used Fewer Home Care Services during the COVID-19 Pandemic: Findings from a Secondary Analysis of an Urgent Survey in Japan.

Background: This study aimed to identify reduced home care use among older people and its impact on user numbers and service provider revenues during the coronavirus disease 2019 (COVID-19) pandemic.

Methods: We conducted this secondary analysis of cross-sectional data from long-term care providers in Japan and estimated the probability of client cancellations and service contraction for institutional and home care services adjusted for the service type, area, size, infection occurrence, and staff employment impacts. We then estimated the rate of change in user numbers and revenue related to reduced usage.

Long-Term Changes in Older Adults' Independence Levels for Performing Activities of Daily Living in Care Settings: A Nine-Year Follow-Up Study.

This study aimed to clarify the variability in the independence profiles of specific activities of daily living (ADL) among older men and women. The research subjects were 5872 older adults (1143 men and 4729 women) certified as requiring nursing care or support (based on data obtained from the nursing care insurance certification survey database) who could be surveyed in both 2009 and 2018. Using item response theory, this study compared longitudinal data of difficulties faced by older adults during ADL.

Causes of changes in basic activities of daily living in older adults with long-term care needs.

Objective: To elucidate basic activities of daily living (BADL) changes, and the causes, in older adults with long-term care needs.

Methods: This retrospective study utilised long-term care insurance (LTCI) certification survey data from 2010 to 2017 in City A.

Results: In decreasing likelihood of requiring assistance, BADL items were grooming, bathing, getting dressed/undressed, mobility, toilet hygiene, functional mobility and self-feeding.

Impact of sensory impairments on dementia incidence and symptoms among Japanese older adults.

Background: Dementia and behavioural and psychological symptoms of dementia affect older adults' care-need levels. With aging comes an increase in the incidence of sensory impairments, which promotes the development of dementia. We investigated the association between sensory impairments - visual impairment (VI), hearing impairment (HI), and dual sensory impairment (DSI), the behavioural and psychological symptoms of dementia, and dementia incidence.

Impact of Outpatient Rehabilitation Service in Preventing the Deterioration of the Care-Needs Level Among Japanese Older Adults Availing Long-Term Care Insurance: A Propensity Score Matched Retrospective Study.

Outpatient rehabilitation (OR) and outpatient day long-term care (ODLC) services are frequently used by older adult patients in Japan. However, there is a need to clarify that OR service, which has more rehabilitation professionals than ODLC, has the role of providing rehabilitation. This retrospective study examined the impact of OR services by comparing the two services based on City A data from the care-needs certification survey conducted between 2015 to 2017.

Clinical status and dependency of the elderly requiring long-term care in Japan.

More than 4 million of the elderly receive long-term care services using the public long-term care insurance in Japan. In order to use the insurance system, the insured person needs to be classified in one of the six care levels according to his/her clinical status. Though each level is defined in terms of the total amount of estimated care time needed per day, the clinical status of each level is not precisely defined.

[A longitudinal study of cognitive function and the relationship between cognition and activities of daily living in the elderly].

Aim: To describe fundamental cognitive function and change in the elderly and examine interaction between cognition and ADL.

Methods: We investigated the mental and physical condition of 12,140 persons aged 65 years or over in 2000 and 2002 according to the Eligibility Survey Questionnaire for Long-term Care Insurance. The percentage correct and correlation coefficients of six items in the Questionnaire concerning "Understanding" : "Understands daily activities", "Answers date of birth and age", "Remembers what the subject did before interview", "Says own name", "Knows what season it is now", "Knows the place where the subject is" were determined.
