RESUMO
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.

RESUMO
PURPOSE: Latent TGF-ß binding protein 4 (LTBP4) is involved in the production of elastin fibers and has been implicated in LTBP4-related cutis laxa and its complication, emphysema-like changes. Various factors have been implicated in the pathogenesis of emphysema, including elastic degeneration, inflammation, cellular senescence, mitochondrial dysfunction, and decreased angiogenesis in the lungs. We investigated the association between LTBP4 and emphysema using human lung fibroblasts with silenced LTBP4 genes. METHODS: Cell contraction, elastin expression, cellular senescence, inflammation, anti-inflammatory factors, and mitochondrial function were compared between the LTBP4 small interfering RNA (siRNA) and control siRNA. RESULTS: Under the suppression of LTBP4, significant changes were observed in the following: decreased cell contractility, decreased elastin expression, increased expression of the p16 gene involved in cellular senescence, increased TNFα, decreased GSTM3 and SOD, decreased mitochondrial membrane potential, and decreased VEGF expression. Furthermore, the decreased cell contractility and increased GSTM3 expression observed under LTBP4 suppression were restored by the addition of N-acetyl-L-cysteine or recombinant LTBP4. CONCLUSION: The decreased elastin expression, cellular senescence, inflammation, decreased antioxidant activity, mitochondrial dysfunction, and decreased VEGF expression under reduced LTBP4 expression may all be involved in the destruction of the alveolar wall in emphysema. Smoking is the most common cause of emphysema; however, genetic factors related to LTBP4 expression and other factors may also contribute to its pathogenesis.
RESUMO
OBJECTIVE: The purpose of the study is to assess if daily use of hypnotics increases mortality, aspiration pneumonia and hip fracture among relatively healthy individuals aged 75 years or older who lead independent lives in the community. METHOD AND PATIENTS: Of the adults aged 75 years or older residing in Hokkaido prefecture of Japan (n = 705,538), those who did not meet several exclusion criteria were eligible for generating propensity score-matched cohorts (n = 214,723). Exclusion criteria included co-prescribed medications acting on the central nervous system, diagnoses of malignant neoplasm, dementia, depression, etc. We compared 33,095 participants who were prescribed hypnotics for daily use (hypnotic group) with a propensity score-matched cohort without a prescription (control group). Participants were followed for more than 42 months. RESULTS: During the 42-month follow-up period, the incidence of the three outcome measures in the hypnotics group was significantly higher than that in the control group (aspiration pneumonia p < 0.001, hip fracture p = 0.007, and all-cause mortality p < 0.001). Sensitivity analyses utilizing inverse probability weighting demonstrated hazard ratios of 1.083 [1.023-1.146] for mortality, 1.117 [1.014-1.230] for aspiration pneumonia, and 1.720 [1.559-1.897] for hip fracture. Meanwhile, the attribute risk differences were 2.7, 1.5, and 1.0 per 1000 patient-years, respectively. CONCLUSIONS: Although daily use of hypnotics increased the risk of three events, their attribute risk differences were fewer than 3.0 per 1000 patient-years. The results will help provide guidance on whether it is reasonable to prescribe hypnotics to geriatric population aged 75 or older leading independent lives in the community.

AIM: The purpose of the present study was to clarify the association of pneumonia admission with polypharmacy and specific drug use in community-dwelling older people. METHODS: Using health insurance and long-term care insurance data from Kure city in Japan, we retrospectively collected data for older community-dwelling people (aged ≥65 years) from April 2017 to March 2019. The outcome was pneumonia admission. We carried out multivariate logistic regression analysis to identify the association of pneumonia admission with polypharmacy (≥5 drugs), the use of psychotropic drugs or anticholinergics with adjustment for patient backgrounds, such as comorbidity, and the daily life independence level for the older people with disability. RESULTS: Of 59 040 older people, 4017 (6.8%) participants were admitted for pneumonia in 2 years. The ratio of polypharmacy, and the use of psychotropic drugs and anticholinergics in the admission group were significantly higher than the non-admission group. Multivariate logistic regression analysis showed that polypharmacy (odds ratio 1.29, 95% confidence interval 1.18-1.41), and the use of conventional antipsychotic drugs (odds ratio 1.39, 95% confidence interval 1.02-1.90), atypical antipsychotic drugs (odds ratio 1.67, 95% confidence interval 1.37-2.05) and anticholinergics (odds ratio 1.22, 95% confidence interval 1.13-1.33) were significantly associated with pneumonia admission. CONCLUSION: The present results suggest that polypharmacy, and the use of psychotropic drugs and anticholinergics are risk factors for pneumonia admission. Geriatr Gerontol Int 2024; 24: 404-409.

BACKGROUND: Frailty often coexists with heart failure (HF), which significantly aggravates the clinical outcomes of older adults. However, studies investigating the interplay between frailty and HF in older adults are scarce. We aimed to assess the prevalence of frailty using the cumulative deficit approach and evaluate the impacts of frailty on health utilization, use of HF-related medications and adverse clinical outcomes (all-cause mortality, all-cause readmissions and HF readmissions) among older HF patients. METHODS: A total of 38 843 newly admitted HF patients were identified from Taiwan's National Health Insurance Research Database and categorized into three frailty subgroups (fit, mild frailty and severe frailty) based on the multimorbidity frailty index. Cox regression models and Fine and Gray subdistribution hazard models were used to estimate the impacts of frailty on clinical outcomes at 1 and 2 years of follow-up. Generalized estimating equation models were further conducted to evaluate the associations between longitudinal and time-varying use of HF-related medications and clinical outcomes among distinct frailty subgroups. RESULTS: Of 38 843 older HF patients (mean age 80.4 ± 8.5 years, 52.3% females) identified, 68.3% were categorized as frail (47.5% of mild frailty and 20.8% of severe frailty). The median number of readmissions (fit: 1 [inter-quartile range-IQR 2], mild frailty: 1 [IQR 2] and severe frailty: 2 [IQR 3]) increased with the severity of frailty. Only 27.3% of HF patients died of cardiovascular diseases regardless of their frailty status. Compared with the fit group, the severe frailty group was associated with increased risk of all-cause mortality (adjusted hazard ratio 1.16, 95% confidence interval [CI] 1.11-1.21), all-cause readmissions (subdistributional hazard ratio (sHR) 1.21, 95% CI 1.16-1.25) and HF-related readmissions (sHR 1.14, 95% CI 1.09-1.20) at 2 years of follow-up. Those who used triple or more HF-related medications were at lower risk for all-cause readmissions (adjusted odds ratio [aOR] 0.49, 95% CI 0.44-0.54) and HF-related readmissions (aOR 0.42, 95% CI 0.37-0.47) at 2 years of follow-up even in the severe frailty group. CONCLUSIONS: Frailty is highly prevalent and associated with increased risk of all-cause mortality, all-cause readmissions and HF readmissions among older HF patients. Those who were using triple or more HF-related medications were at lower risk of adverse clinical outcomes across distinct frailty subgroups. Further studies are needed to optimize the treatment strategies for older HF patients with distinct frailty status.

Background: Asthma and chronic obstructive pulmonary disease (COPD) overlap (ACO) is characterized by concurrent features of asthma and COPD. Since disease pathogenesis, severities, and treatments differ between asthma and ACO, it is important to differentiate them. Objective: To clarify and compare the characteristics of ACO and asthma and identify the serum biomarkers for differentiating them, especially in older patients. Methods: This study used the data of 639 participants from the nationwide cohort study, the NHOM-Asthma study, an asthma registry in Japan, with complete information on smoking history, respiratory function, and serum biomarkers. ACO was defined as the self-reported comorbidity of COPD or emphysema, or with obstructive pulmonary function and smoking history (pack-years≥10). The clinical characteristics of patients with ACO and asthma without COPD were compared. The serum biomarkers for differentiation were examined using receiver operating characteristic curves and multivariable analysis. The associations between the biomarkers and age were also analyzed. Results: Of the 639 asthma patients, 125 (19.6%) were diagnosed with ACO; these patients were older and male-dominant and had a higher prevalence of comorbidities such as hypertension, diabetes, and stroke. Among the serum biomarkers that were significantly different between ACO and asthma without COPD, the YKL-40/CHI3L1, MMP3, and IL-1RA levels showed a high area under the curve for discriminating ACO. Only the MMP3 and IL-1RA levels were significantly higher among ACO patients, regardless of age and sex; the YKL-40/CHI3L1 levels were not different due to the effect of age. Conclusion: MMP3 and IL-1RA may be useful serum biomarkers for distinguishing ACO from asthma.
RESUMO
BACKGROUND: With rising worldwide population aging, the number of homebound individuals with multimorbidity is increasing. Improvement in the quality of home medical care (HMC), including medications, contributes to meeting older adults' preference for "aging in place" and securing healthcare resources. OBJECTIVE: To evaluate the changes in drug prescriptions, particularly potentially inappropriate medications (PIMs), among older adults receiving HMC in recent years, during which measures addressing inappropriate polypharmacy were implemented, including the introduction of clinical practice guidelines and medical fees for deprescribing. DESIGN: A cross-sectional study. PARTICIPANTS: Using data from the national claims database in Japan, this study included older adults aged ≥ 75 years who received HMC in October 2015 (N = 499,850) and October 2019 (N = 657,051). MAIN MEASURES: Number of drugs, prevalence of polypharmacy (≥ 5 regular drugs), major drug categories/classes, and PIMs according to Japanese guidelines were analyzed. Random effects logistic regression models were used to evaluate the differences in medications between 2015 and 2019, considering the correlation within individuals who contributed to the analysis in both years. KEY RESULTS: The number of drugs remained unchanged from 2015 to 2019 (median: 6; interquartile range: 4, 9). The prevalence of polypharmacy also remained unchanged at 70.0% in both years (P = 0.93). However, the prescription of some drugs (e.g., direct oral anticoagulants, new types of hypnotics, acetaminophen, proton pump inhibitors, and ß-blockers) increased, whereas others (e.g., warfarin, vasodilators, H2 blockers, acetylcholinesterase inhibitors, and benzodiazepines) decreased. Among the frequently prescribed PIMs, benzodiazepines/Z-drugs (25.6% in 2015 to 21.1% in 2019; adjusted odds ratio: 0.52) and H2 blockers (11.2 to 7.3%; 0.45) decreased, whereas diuretics (23.8 to 23.6%; 0.90) and antipsychotics (9.7 to 10.5%; 1.11) remained unchanged. CONCLUSIONS: We observed some favorable changes but identified some continuous and new challenges. This study suggests that continued attention to medication optimization is required to achieve safe and effective HMC.

BACKGROUND: Polypharmacy and potentially inappropriate medications (PIM) are widely recognized as vital quality indicators of pharmacotherapy in older adults. As Taiwan and Japan grapple with the ongoing challenges of population aging, obtaining an accurate understanding of the prevalence of these indicators is crucial for developing effective strategies to optimize pharmacotherapy in older populations. The present study aims to comprehensively evaluate the prevalence of polypharmacy and PIMs in Taiwan and two Japanese cohorts, shedding light on the similarities and differences in prescribing practices across these populations. METHODS: This study employed a cross-sectional design to investigate individuals aged ≥65 years in Taiwan, as well as two Japanese cohorts: Japan Cohort 1 (dispensing data from chain pharmacies; year 2014 and 2019) and Japan Cohort 2 (claims data; year 2017 and 2019). The prescription records of these participants were collected from the national claims database in Taiwan for the years 2014, 2017, and 2019. To identify polypharmacy and hyper-polypharmacy, the study defined the use of 5-9 and 10+ drugs, respectively. Furthermore, the study identified PIMs based on the STOPP-J criteria. Notably, the study further explored the most frequently used PIMs (by categories) in Taiwan. RESULTS: In the year 2019, the prevalence of polypharmacy exhibited similar rates in Taiwan (35.4%) and Japan Cohort 2 (33.1%), while surpassing that of Japan Cohort 1 (25.6%). Nonetheless, the incidence of PIMs in Taiwan was the highest (66.5%), exceeding those of the two Japanese cohorts (Cohort 1: 43.7% and Cohort 2: 40.2%) in the same year. Notably, the top three categories of commonly used PIMs in Taiwan comprised non-steroidal anti-inflammatory drugs (NSAIDs), antithrombotic drugs, and benzodiazepines. CONCLUSIONS: This study highlights the varying prevalence of polypharmacy and PIMs between Taiwan and Japan, but emphasizes the need for collaborative efforts towards optimizing pharmacotherapy in older adults.

BACKGROUND: Clinical evidence demonstrating a longitudinal association between prescribed medications and sarcopenia onset is lacking. We investigated the association of polypharmacy (the use of five or more medications) and potentially inappropriate medications (PIMs) with sarcopenia risk in community-dwelling older adults. METHODS: In this longitudinal population-based cohort study, 2,044 older residents with no long-term care needs were randomly selected from a community in Kashiwa, Japan. Baseline data collection was conducted in 2012, with follow-ups in 2013, 2014, 2016, 2018, and 2021. Prescribed medications and PIMs (drugs listed in the Screening Tool for Older Person's Appropriate Prescriptions for the Japanese or potentially muscle-wasting drugs) were identified through interviews. New-onset sarcopenia was identified according to the 2019 criteria of the Asian Working Group for Sarcopenia over a 9-year period and analyzed. We used Cox proportional hazards models to test the longitudinal association of prescribed medications with sarcopenia onset. RESULTS: Of the 1,549 participants without sarcopenia at baseline (mean age, 72.5 ± 5.5 years; 49.1% women; median and interquartile range, 6.0 [4.0-9.0] years), 230 experienced new-onset sarcopenia during the follow-up. After adjusting for confounders, polypharmacy combined with PIM use was strongly associated with new-onset sarcopenia (adjusted hazard ratio, 2.35; 95% confidence interval, 1.58-3.51; P < 0.001). No significant associations were observed for either PIM use or polypharmacy alone. CONCLUSIONS: Polypharmacy combined with PIM use, but not polypharmacy alone, was associated with an increased risk of new-onset sarcopenia over the 9-year follow-up period among community-dwelling older adults. Limiting polypharmacy and imposing the prescription of appropriate medications may facilitate sarcopenia prevention.

Older adults are likely to develop adverse drug events owing to age-related changes in pharmacokinetics and polypharmacy. In terms of pharmacokinetics, the drug should be prescribed at a reduced dose, which should be reconsidered and reduced during long-term use. For polypharmacy, "List of drugs to be prescribed with special caution" should be referred and deprescription should be practiced in consideration of the priority of treatment. Because older adults often show reduced ability to manage their medication due to cognitive dysfunction, low visual acuity, and hearing loss, measures should be taken to maintain their adherence.

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.

AIMS: To investigate the influence of disability severity level on polypharmacy and the prescription of potentially inappropriate medication (PIM) using health insurance and long-term care (LTC) insurance claim data. METHODS: Data were obtained from a health-care insurance and long-term care insurance claims database of citizens of Kure city, Japan, in April 2017. Data including age, sex, and drug profile were obtained, and the level of LTC needs was used to measure disability level. Factors associated with polypharmacy (≥5 prescribed drugs) and PIM prescription (≥1 PIM) defined by STOPP-J were analyzed statistically. RESULTS: Among 67,169 people aged ≥65 (mean age 77.2 ± 7.9, male 40.7%), the frequency of polypharmacy increased with age until 85-89 (male 58.3%, female 57.6%) in both genders, and polypharmacy was most prevalent in those at the mildest LTC level (support level: male 68.9%, female 73.7%). PIM prescriptions was also frequent in those with LTC needs. On multiple logistic regression analysis, polypharmacy was significantly associated with older age and LTC needs, and PIM prescription was associated with older age and higher LTC level, suggesting that there is a large difference in prescription according to the person's age and disability level. CONCLUSION: Polypharmacy was prevalent especially in older persons which peaked at the age of 85-89 or at mild disability level, and PIM prescription was prevalent in those with older age and higher care levels. When optimizing polypharmacy or PIM prescription in older patients, healthcare providers should focus on not only age but also disability level.

BACKGROUND: Muscle disuse results in loss of skeletal muscle mass and function. Hochu-ekki-to (TJ-41; Bu-Zhong-Yi-Qi-Tang in Chinese) is an herbal medicinal formulation used to treat patients with frailty, fatigue and appetite loss. It has been suggested that two atrogenes, atrogin-1 and muscle Ring finger 1 (MuRF1), are ubiquitin ligases involved in disuse-induced muscle atrophy and that 5' adenosine monophosphate-activated protein kinase (AMPK) is involved in skeletal muscle metabolism. Effects of TJ-41 on disuse-induced muscle atrophy are unclear. METHODS: We subjected differentiated C2C12 myotubes to serum starvation, then examined the effects of TJ-41 on atrogenes expression, AMPK activity and the morphology of the myotubes. Male C57BL/6J mice were subjected to tail-suspension to induce hindlimb atrophy. We administered TJ-41 by gavage to the control group and the tail-suspended group, then examined the effects of TJ-41 on atrogene expression, AMPK activity, and the muscle weight. RESULTS: Serum starvation induced the expression of atrogin-1 and MuRF1 in C2C12 myotubes, and TJ-41 significantly downregulated the expression of atrogin-1. Tail-suspension of the mice induced the expression of atrogin-1 and MuRF1 in skeletal muscle as well as its muscle atrophy, whereas TJ-41 treatment significantly downregulated the expression of atrogin-1 and ameliorated the loss of the muscle weight. In addition, TJ-41 also activated AMPK and inactivated Akt and mTOR in skeletal muscle in vivo. CONCLUSION: TJ-41 inhibited atrogenes in an Akt-independent manner as well as activating AMPK in skeletal muscles in vivo, further implying the therapeutic potential of TJ-41 against disuse-induced muscle atrophy and other atrogenes-dependent atrophic conditions.

AIM: Older adults at the end-of-life stage receiving home visits from physicians often experience symptoms such as dyspnea, pain and fatigue, among others. This study aimed to investigate the practices and opinions of physicians providing home visits regarding palliative care for older adults with respiratory symptoms due to non-malignant diseases in Japan. METHODS: A nationwide questionnaire survey on home palliative care for non-cancer chronic respiratory diseases was sent to 2988 home-care physicians in 2020 through postal mail and/or email. The questions focused on their background, their use of rating scales to evaluate the intensity of dyspnea, and their practices and opinions regarding home palliative care for respiratory diseases or symptoms. RESULTS: Valid responses were collected from 592 physicians (19.8%). A total of 251 participants (43.1%) used a rating scale to evaluate the intensity of dyspnea. While 87.8%, 86.6%, 67.3%, and 60.0% of physicians considered pulmonary rehabilitation, morphine, sedative medications, and non-invasive positive pressure ventilation (NPPV), respectively, as effective in relieving respiratory distress, 73.0%, 66.9%, 57.3%, and 55.2% of those physicians, respectively, used each modality to relieve respiratory distress. Frequently involved physicians in the aforementioned care prescribed morphine or sedative medications and used NPPV more frequently. CONCLUSIONS: This study found a discrepancy between the proportion of physicians who considered palliative care as effective and those who prescribed it. Geriatr Gerontol Int 2022; 22: 943-949.

OBJECTIVES: This study aimed to evaluate the prescription patterns of drugs during the last year of life in homebound older adults who received home medical care. METHODS: We used a nationwide claims database in Japan and selected older adults aged ≥75 years who received home medical care services from ≥12 months before their death. We evaluated medications prescribed 12 months before death (month 12), 3 months before death (month 3) and in the last month of life (month 1). We explored the factors associated with the decreased number of cardiovascular preventive drugs from month 12 to both month 3 and month 1. RESULTS: A total of 118 661 participants were included, and the majority were aged ≥90 years and women. The prevalence of cardiovascular preventive drugs decreased but remained common in month 1, which included antihypertensives (34.7%), antiplatelets (15.9%), oral anticoagulants (7.6%), antidiabetic drugs (7.3%) and lipid-lowering drugs (6.1%). The relative decrease from month 12 to month 1 was the largest for lipid-lowering drugs (44.8%) and the smallest for oral anticoagulants (13.6%). Among other drugs, laxatives (enema), antiemetics, oral corticosteroids, analgesics, expectorants, bronchodilators and antibiotics showed a large relative increase. Older age, duration of home medical care services for <1 year and diagnoses of cancer, dementia and Parkinson's disease were associated with a greater likelihood of a decreased number of cardiovascular preventive drugs. CONCLUSIONS: There is room for deprescribing to avoid inappropriate polypharmacy by balancing preventive and symptom management drugs in those receiving home medical care with a limited life expectancy.
RESUMO
Background: Polypharmacy and its adverse drug events are a major healthcare challenge related to falls, hospitalisations and mortality. Comprehensive geriatric assessment (CGA) may contribute to polypharmacy improvement, however, there is no clear evidence so far. Methods: Using a national inpatient database in Japan from April 1, 2014 to March 31, 2018, we investigated the association between CGA and polypharmacy. We identified patients aged ≥65 years admitted for ischaemic stroke who could receive oral medications. Propensity score matching was conducted for patients with and without CGA during hospitalisation. The outcomes were polypharmacy (defined as use of five or more types of oral medications) at discharge, the number of medication types prescribed at discharge, and the difference between the numbers of medication types prescribed on admission and at discharge. Findings: A total of 162,443 patients were analysed, of whom 39,356 (24·2%) received CGA, and propensity score matching identified 39,349 pairs. Compared with non-CGA group, the CGA group had a significantly lower proportion of polypharmacy at discharge (34·3% vs. 32·9%, p < 0·001) and a smaller number of medication types prescribed at discharge (3·84 vs. 3·76, p < 0·001). Interpretation: This study shows the clear evidence that there is a positive relationship between CGA and a reduction in the number of medications in older inpatients with ischaemic stroke. Funding: The Ministry of Health, Labour and Welfare, Japan and the Ministry of Education, Culture, Sports, Science and Technology, Japan.
RESUMO
BACKGROUND: To elucidate recent prescription trends for older adults and the background underlying changes over time with a particular focus on the prevalence of polypharmacy and potentially inappropriate medications (PIMs). METHODS: We cross-sectionally collected prescription data of patients aged â§65 years who visited chain pharmacies dispensing prescribed drugs from all types of outpatient settings for one month in two sampling periods (October, 2014 and December, 2019), and the data were analysed. Prevalence of polypharmacy and factors associated with PIMs between the two periods were investigated. RESULTS: The average number of drugs prescribed decreased over time (4.05 ± 3.24 in 2014 vs. 3.98 ± 3.16 in 2019, p < 0.001), as did the prevalence of polypharmacy (50.1% in 2014 vs. 48.2% in 2019, p < 0.001). Meanwhile, the prevalence of PIMs exhibited a marked increase (overall: 26.8% in 2014 vs. 43.7% in 2019, aged 65-74: 25.6% in 2014 vs. 40.3% in 2019, aged 75-84: 27.4% in 2014 vs. 43.9% in 2019), which was the most pronounced in patients aged over 85 (29.4% in 2014 vs. 53.0% in 2019). The number of classes of drugs positively associated with PIMs in 2019 increased from that in 2014. The increasing trend was most prominently observed in the oldest age category (over 85 years, 2 in 2014 vs. 6 in 2019). CONCLUSIONS: The comparison of monthly prescribing data with an interval of 5 years suggested an increasing trend in the prevalence of PIMs, contrary to the declining prevalence of polypharmacy.

General muscle health declines with age, and in particular, sarcopenia-defined as progressive loss of muscle mass and strength/physical performance-is a growing issue in Asia with a rising population of community-dwelling older adults. Several guidelines have addressed early identification of sarcopenia and management, and although nutrition is central to treatment of sarcopenia, there are currently few guidelines that have examined this specifically in the Asian population. Therefore, the Asian Working Group for Sarcopenia established a special interest group (SIG) comprising seven experts across Asia and one from Australia, to develop an evidence-based expert consensus. A systematic literature search was conducted using MEDLINE on the topic of muscle health, from 2016 (inclusive) to July 2021, in Asia or with relevance to healthy, Asian community-dwelling older adults (≥60 years old). Several key topics were identified: (1) nutritional status: malnutrition and screening; (2) diet and dietary factors; (3) nutritional supplementation; (4) lifestyle interventions plus nutrition; and (5) outcomes and assessment. Clinical questions were developed around these topics, leading to 14 consensus statements. Consensus was achieved using the modified Delphi method with two rounds of voting. Moreover, the consensus addressed the impacts of COVID-19 on nutrition, muscle health, and sarcopenia in Asia. These statements encompass clinical expertise and knowledge across Asia and are aligned with findings in the current literature, to provide a practical framework for addressing muscle health in the community, with the overall aim to encourage and facilitate broader access to equitable care for this target population.
