The outcome was the new certification of long\u2010term 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.<\/jats:p><\/jats:sec><jats:sec><jats:title>Result<\/jats:title><jats:p>During the follow\u2010up period, 727 (4.0%) participants had an incident disability (median follow up 457\u2009days [quartile range 408\u2013519\u2009days]). The QMCOO's predictive accuracy for new long\u2010term care needs was optimal when the total score of 3\/4 was used as the threshold. Older adults with scores \u22654 had a higher adjusted hazard ratio for incident disability (adjusted hazard ratio 2.5, 95% confidence interval 2.1\u20132.9). Furthermore, the adjusted hazard ratio was greatly enhanced with comorbidity (6.6, 95% confidence interval 4.8\u20138.9).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>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\u2010term care, even among the old\u2010old in the latter stage who tended to suffer from multimorbidity. <jats:bold>Geriatr Gerontol Int 2023; 23:
