Aim: To enhance health services that can address multifaceted issues, the Questionnaire for Medical Checkup of Old-Old (QMCOO) was strategically developed to ascertain frailty status. Using the National Health Insurance database system, we aimed to clarify whether the QMCOO can predict new certifications for long-term care for disabilities., Method: Of 20 151 adults aged ≥75 years who underwent health checkups in Kashiwa City, Japan, in fiscal year 2020 (examination rate 36.8%), 18 130 persons were included (mean age 80.1 ± 4.1 years, 55.1% women). The outcome was the new certification of long-term care until January 2022. From the medical care receipt data, QMCOO, age, sex, living arrangement, body mass index, comorbidity, and musculoskeletal and connective tissue diseases were evaluated., Result: During the follow-up period, 727 (4.0%) participants had an incident disability (median follow up 457 days [quartile range 408-519 days]). The QMCOO's predictive accuracy for new long-term care needs was optimal when the total score of 3/4 was used as the threshold. Older adults with scores ≥4 had a higher adjusted hazard ratio for incident disability (adjusted hazard ratio 2.5, 95% confidence interval 2.1-2.9). Furthermore, the adjusted hazard ratio was greatly enhanced with comorbidity (6.6, 95% confidence interval 4.8-8.9)., Conclusion: The QMCOO, which reflects multifaceted frailty, might be predictive of incident disability, and its predictive accuracy could be improved by considering comorbidities. The comprehensive QMCOO could contribute to extending healthy life expectancy through efficiently assessing health care and preventing long-term care, even among the old-old in the latter stage who tended to suffer from multimorbidity.

Background: Frailty, which is defined as aging-related multisystem impairments, can lead to adverse health outcomes. However, evidence for such a connection in Chinese older adults remains lacking. This study examined the association between frailty and future falls and disability among community-dwelling Chinese older adults., Methods: Data were obtained from the 2011 and 2015 waves of the China Health and Retirement Longitudinal Study. Participants were aged 60 years and above at baseline in 2011 and completed the follow-up survey in 2015. Outcome measures were future falls, incident disability in activities of daily living (ADLs) and instrumental activities of daily living (IADLs), and worsening performance of ADLs and IADLs. A multivariate logistic regression was conducted to examine the association between frailty phenotype and falls, incident disability, and worsening disability during a four-year period., Results: We found that frail participants were at increased risk at follow-up for: falls (OR 1.54, 95% CI, 1.14-2.08); developing new ADL difficulties (OR 4.10, 95% CI, 2.79-6.03) and IADL difficulties (OR 3.06, 95% CI, 2.03-4.61); and worsening ADLs performance (OR 2.27, 95% CI, 1.27-4.06), after adjusting for potential confounders. Prefrailty was also significantly associated with future falls, incident disability in ADLs and IADLs, but with a lower magnitude of effect., Conclusions: Frailty phenotype is an independent predictor of future falls, incident disability, and worsening performance in ADLs among Chinese older adults. The association suggests the need to pay special attention in caring for frail and prefrail elders and improving individuals' frailty status.
