Aim: The importance of comprehensive geriatric assessment (CGA) is increasing in aging societies worldwide. However, there are few comprehensive studies on CGA, resulting in a limited understanding of its implementation rate, temporal changes and factors associated with its implementation. We aimed to investigate the implementation status of CGA and its regional variance in Japan. Methods: Using the Diagnosis Procedure Combination database, we investigated CGA trends, and identified the patient, hospital and regional factors associated with its implementation. We identified patients aged ≥65 years who were admitted for the first time between 2016 and 2020 with a diagnosis of stroke, heart failure, pneumonia, bone fracture or colorectal cancer. We examined the CGA implementation rate according to patient and hospital characteristics. We also investigated temporal changes and tendencies to carry out CGA in different prefectures. Results: A total of 1 974 817 patients were analyzed, of whom 570 696 (28.9%) underwent CGA. The implementation trend increased steadily from 25.3% in fiscal year 2016 to 33.4% in fiscal year 2019. The implementation rate also increased with patient age (30.3% in patients aged ≥95 years). Regional variations in its implementation status were observed, with a higher tendency to be implemented in areas near major metropolitan regions. A trend toward carrying out CGA for colorectal cancer, but not for other diseases, has been observed in eastern Japan. Conclusion: Although CGA is increasingly carried out, considerable regional differences remain in its implementation status. Initiatives to reduce variations are necessary.

Aim: Patients with dementia with Lewy bodies (DLB) are at a high risk for falls and fractures. Although cholinesterase inhibitors reportedly are effective in suppressing the progression of cognitive symptoms in DLB patients, their effects on fracture risk remain unclarified. This study aimed to evaluate the association between donepezil use and hip fracture risk in older patients with DLB. Methods: Using the Japanese insurance claim database, we collected the data of patients aged ≥65 years with DLB from April 2012 to March 2019. After propensity score matching, we compared the fracture rate over 3 years between DLB patients receiving donepezil and those not receiving antidementia drugs. Results: Altogether, 24 022 239 individuals aged ≥65 years were newly registered from April 2012 to March 2016 and had verifiable information from 6 months before to 3 years after the registration. We identified 6634 pure‐DLB patients and analyzed the data of 1182 propensity score‐matched pairs. The characteristics, including age, sex, fracture history, osteoporosis, and bone mineral density test rate, of the two groups were well balanced by propensity score matching. The incidence rate of hip fracture was significantly lower in DLB patients receiving donepezil than in those not receiving antidementia drugs (0.60 vs. 1.44/100 person‐years, P < 0.001), whereas that of vertebral fractures was the same. Conclusions: Donepezil administration in Japanese people aged ≥65 years with DLB was significantly associated with a decreased risk of hip fracture. Donepezil may provide new benefits to DLB patients. Geriatr Gerontol Int 2024; 24: 782–788. [ABSTRACT FROM AUTHOR]

Patients with osteoporosis are prone to fragility fractures. Evidence of the effects of active forms of vitamin D on hip fracture prevention is insufficient. We examined the association between vitamin D prescription and incidence of new fractures using the data of osteoporotic patients from the nationwide health insurance claims database of Japan. The follow-up period was 3 years after entry. The untreated patients were never prescribed vitamin D during follow-up (n = 422,454), and the treated patients had a vitamin D medication possession ratio of ≥ 0.5 at all time points (n = 169,774). Propensity score matching was implemented on these groups, yielding 105,041 pairs, and subsequently, the control and treatment groups were established and analyzed. The incidence of new fractures was significantly lower in the treatment group compared with the control group (6.25% vs. 5.69%, hazard ratio 0.936 [95% confidence interval 0.904–0.970], p < 0.001*). By site, hip fractures significantly decreased (0.89% vs. 0.42%, p < 0.001), but not vertebral and radial fractures. Subgroup analysis by vitamin D type showed a significantly lower incidence of total fractures only in alfacalcidol (hazard ratio 0.676 [95% confidence interval 0.628–0.728], p < 0.001*). The results suggest that vitamin D prescription was associated with a reduced incidence of hip fractures. [ABSTRACT FROM AUTHOR]

Aim: Hypnotics might increase the risk of falls and fractures in older patients with neurocognitive disorders. Orexin receptor antagonists have recently been approved, but the relationship between the new drugs and fractures remains unclarified. This study aimed to evaluate the association between the type of hypnotic and in‐hospital fractures in older patients with neurocognitive disorders using a nationwide inpatient database. Methods: Using the Japanese Diagnosis Procedure Combination database, we collected information on inpatients aged ≥65 years with neurocognitive disorders between April 2014 and March 2021. We examined trends in the prescription patterns of benzodiazepine drugs, Z‐drugs, orexin receptor antagonists and melatonin receptor agonists. We also carried out a 1:4 matched case–control analysis of in‐hospital fractures. The odds ratio of each hypnotic drug was estimated using a generalized estimating equation with adjustment for walking ability, comorbidities, osteoporosis, dialysis, selective serotonin reuptake inhibitor use and anti‐dementia drug use. Results: The prescription of benzodiazepine hypnotics decreased and that of orexin receptor antagonists increased. This case–control analysis included 6832 patients with fractures and 23 463 controls. Ultrashort‐acting benzodiazepines, short‐acting benzodiazepines and Z‐drugs were associated with an increased risk of bone fracture (odds ratio [95% confidence interval] 1.38 [1.08–1.77], 1.38 [1.27–1.50], 1.49 [1.37–1.61], respectively). Orexin receptor antagonists were not associated with an increased risk of bone fracture (1.07 [0.95–1.19]). Conclusions: In contrast to other types of hypnotics, orexin receptor antagonists were not associated with in‐hospital fractures in older patients with neurocognitive disorders. Geriatr Gerontol Int 2023; 23: 500–505. Recent trend in hypnotics prescription rates in Japanese older inpatients with neurocognitive disorders. In contrast to other types of hypnotics, orexin receptor antagonists were not associated with in‐hospital fractures among these patients. [ABSTRACT FROM AUTHOR]

This retrospective study aimed to evaluate the association between antidementia medication use and incidence of new vertebral, hip, and radial fractures in patients with Alzheimer's dementia (AD). We used the nationwide health insurance claims database of Japan from 2012 to 2019 and identified 12,167,938 patients aged ≥ 65 years who were newly registered from April 2012 to March 2016 and had verifiable data receipt from half-year before to 3 years after the registration. Among these patients, 304,658 were diagnosed with AD and we showed the prescription status of antidementia and osteoporosis medication among them. Propensity score matching was conducted for AD group with and without antidementia medication use, and 122,399 matched pairs were yielded. The incidence of hip fractures (4.0% vs. 1.9%, p < 0.001) and all clinical fractures (10.5% vs. 9.0%, p < 0.001) significantly decreased and that of radial fractures increased (0.6% vs. 1.0%, p < 0.001) in AD patients with antidementia medication use compared with AD patients without antidementia medication use. No significant difference was found in vertebral fractures (6.6% vs. 6.5%, p = 0.51). Overall, these results suggest a positive relationship between antidementia medication use and fracture prevention in patients with AD. [ABSTRACT FROM AUTHOR]

Background: Frailty is a state of increased vulnerability to poor resolution of homeostasis following a stress. Early diagnosis and intervention of frailty are essential to prevent its adverse outcomes. However, simple diagnostic criteria have not been established. The Questionnaire for Medical Checkup of Old-Old (QMCOO) is widely used for medical checkups of older adults in Japan. In our previous report, we developed a method to score the QMCOO and showed that frailty can be diagnosed with the highest accuracy when the score cutoff was set at 3/4 points. We aimed to validate the criteria in a larger cohort. Methods: Participants aged 65 years or over were recruited in the western region of Japan. They answered all the items of the Kihon Checklist (KCL) and the QMCOO. Based on the KCL score, they were diagnosed as robust (3 or lower), prefrail (4 to 7), or frail (8 or over). Then we tested the effectiveness to diagnose frailty using the QMCOO cutoff of 3/4 points. We also aimed to determine the score cutoff to separate robust and prefrail. Results: 7,605 participants (3,458 males and 4,147 females, age 77.4 ± 6.9 years) were recruited. 3,665 participants were diagnosed as robust, 2,448 were prefrail, and 1,492 were frail based on the KCL score. The diagnosis of frailty had a sensitivity of 84.0%, specificity of 82.5%, and accuracy of 82.8% with a QMCOO score cutoff of 3/4 points, suggesting its validity. To separate robust and prefrail, both the accuracy and the Youden index were the highest with the QMCOO cutoff of 2/3 points (sensitivity, specificity, and accuracy were 63.9%, 83.4%, and 75.6%, respectively). All the questions of the QMCOO except Q12 (about smoking) were significantly related to prefrailty status after a logistic regression analysis. Conclusion: Diagnosis of frailty using the QMCOO score cutoff of 3/4 points was validated. Prefrailty could be diagnosed using the score cutoff of 2/3 points. [ABSTRACT FROM AUTHOR]

Aim: Although frailty could be reversible by early diagnosis and interventions, it lacks definite diagnostic criteria. The Kihon Checklist is a 25‐item questionnaire that diagnoses frailty with a cutoff score of 7/8. The Questionnaire for Medical Checkup of Old‐Old (QMCOO) was recently established and used for medical checkups among Japanese older adults, but no method or cutoff score for diagnosing frailty has been established. Thus, we aimed to diagnose frailty using the QMCOO and to determine its cutoff score by comparing it with that of the Kihon Checklist. Methods: We recruited 223 older adults in Yasugi City and Yonago City to answer all the questions in the Kihon Checklist and the QMCOO at the same time. Those scoring ≥8 for the Kihon Checklist (n = 38) were diagnosed as frail. We also determined the cutoff score for frailty for the QMCOO and examined which questionnaire items affected the frailty status. Results: The QMCOO and the Kihon Checklist score showed a significant positive correlation (r = 0.670, P < 0.001). The area under the curve was 0.851. A cutoff score of 3/4 for the QMCOO represented the best results (sensitivity, 76.3%; specificity, 88.1%; and accuracy, 86.1%). Multiple linear regression analysis revealed that subjective health status, body weight loss, slowness, and forgetfulness still affected the frailty status. Conclusions: A cutoff score of 3/4 for the QMCOO might be effective in diagnosing frailty. Geriatr Gerontol Int 2022; 22: 127–131. [ABSTRACT FROM AUTHOR]
