Categorization using the Dementia Assessment Sheet for Community-Based Integrated Care System 8-items (DASC-8) based on cognitive function and activities of daily living predicts frailty, disability and mortality in older adults.

AIM: This longitudinal study aimed to determine whether categorization by the Dementia Assessment Sheet for Community-based Integrated Care System 8-items (DASC-8) is associated with risk of frailty onset, disability, and mortality. METHODS: We analyzed longitudinal data from outpatients aged 65 years and older evaluated for the DASC-8 at the Frailty Clinic. The outcomes during the 3-year follow-up period were (Study A) frailty onset (Kihon Checklist ≥8) and (Study B) disability (new certification of nursing care needs) or mortality. Multivariate Cox regression analyses were performed to examine independent associations between the DASC-8 category and outcomes, and hazard ratios and 95% confidence intervals (CIs) were calculated after adjustment for age, sex, and the presence or absence of diabetes, hypertension, and dyslipidemia. RESULTS: (Study A) Out of the 216 patients without frailty in Categories I or II at baseline, 40 (20.4%) and 11 (55.0%) developed frailty, respectively. The adjusted hazard ratio was 3.62 (95% CI: 1.69-7.76, P < 0.001). (Study B) Out of the 350 patients who did not require long-term care at baseline, disability or death occurred for 20 (7.3%) in Category I, 14 (23.0%) in Category II, and 9 (56.3%) in Category III. The adjusted hazard ratios were 2.40 (Category I vs. II; 95% CI: 1.13-5.11, P = 0.023) and 5.43 (Category I vs. III; 95% CI: 2.23-13.3, P < 0.001). CONCLUSION: Categorization according to DASC-8 is associated with the risk of frailty, disability, and mortality in older patients. Geriatr Gerontol Int 2024; 24: 150-155.

Use of Dementia Assessment Sheet for Community-based Integrated Care System 8-items (DASC-8) for the screening of frailty and components of comprehensive geriatric assessment.

AIM: We examined whether the Dementia Assessment Sheet for Community-based Integrated Care System 8-items (DASC-8) is useful for screening frailty and as a comprehensive geriatric assessment (CGA). METHODS: Outpatients (N = 431; 269 women; Mage = 78.9 ± 6.8 years) with cardiometabolic disease from a frailty clinic participated. Frailty status was assessed using modified Cardiovascular Health Study criteria, the Clinical Frailty Scale and the Kihon Checklist. Cognition, higher-level activities of daily living, sarcopenia, physical activities, depression, nutrition, medication adherence, social network and quality of life were assessed as CGA components. We examined the association of DASC-8 category with frailty or CGA components using multiple logistic regression analyses, adjusted for age and sex. RESULTS: Most participants (n = 310, 71.9%) were in Category I, 90 (20.9%) were in Category II and 31 (7.1%) were in Category III. There were no significant differences in sex, body mass index, or past medical history, except regarding age or cerebral infarction. Logistic regression analyses showed that, for all definitions of frailty, the odds ratios of frailty significantly increased as category progressed. Cognitive function, higher-level activities of daily living, handgrip strength, gait speed, physical activities, medication adherence, social network and quality of life decreased as the category increased. Although depressive tendency increased in Category II, there was no significant difference in muscle mass or prevalence of sarcopenia among the categories. Malnutrition was observed in Category III. CONCLUSIONS: DASC-8 category was associated with frailty and several CGA components in older patients with cardiometabolic disease. Geriatr Gerontol Int 2020; 20: 1157-1163.

Development of the Dementia Assessment Sheet for Community-based Integrated Care System 8-items, a short version of the Dementia Assessment Sheet for Community-based Integrated Care System 21-items, for the assessment of cognitive and daily functions.

AIM: The present study aimed to: (i) examine the reliability and validity of the Dementia Assessment Sheet for Community-based Integrated Care System 21-items for classifying patients to the appropriate categories for glycemic targets in older patients; and (ii) develop a short version of the tool and examine its reliability and validity. METHODS: A total of 410 older individuals were recruited for this multicenter cross-sectional study. We classified them into three categories used for determining the glycemic target in older patients in Japan based on cognitive functions and activities of daily living. Exploratory factor analyses were used to select the eight items of the shorter version. The reliability and validity of the assessment tools were assessed using Cronbach's alpha coefficients and receiver operating characteristic analyses, respectively. RESULTS: The Dementia Assessment Sheet for Community-based Integrated Care System 21-items had three latent factors: cognitive function, instrumental activities of daily living and basic activities of daily living. The Dementia Assessment Sheet for Community-based Integrated Care System 8-items was developed based on each factor load quantity and was confirmed to have a strong correlation with the original version (r = 0.965, P < 0.001). Both tools significantly discriminated older adults belonging to category I from those belonging to category II or III, and category III from category I or II. CONCLUSIONS: Both tools had sufficient internal consistency and validity to classify older patients into the categories for determining the glycemic target in this population based on cognitive and daily functions.
