Prescription Patterns of Antidementia and Psychotropic Drugs in People Living With Dementia: Findings From the Clinical Pathway Study of Alzheimer's Disease in China

Patterns, determinants, and outcomes of early use of antidementia drugs: A 6-year multicenter cohort study in Thailand

BACKGROUND

Evidence on antidementia drugs (ADD) use in developing countries, where accessibility to ADD is challenging, is limited. Our aim was to examine prescribing patterns, factors, and outcomes associated with the early-ADD use (within 3 months from diagnosis) in people with dementia.

METHODS

A retrospective cohort study included individuals aged ≥ 60 years with dementia from three hospitals in Thailand between 2015 and 2020. Participants were categorized as non-ADD users, early-ADD users, and delayed users. ADD switching and one-year persistence were analyzed. Multivariable logistic regression was used to identify factors associated with early-ADD prescribing and its impact on clinical outcomes, including in-hospital death and hospitalization.

RESULTS

3,116 patients were included. The ADD prescription rate was 14.31 %, with 79.82 % of those being early-ADD users. Donepezil was the most prescribed (70.18 %). The one-year persistence rate of any ADD was 24.89 %. Factors associated with early-ADD use included the Civil Servant Medical Benefit Scheme, dyslipidemia, and dementia type. Early-ADD use was associated with reduced in-hospital death (adjusted odds ratio [aOR]=0.46, 95 % CI: 0.22-0.96, p = 0.038) and hospitalization (adjusted OR = 0.70 95 % CI: 0.51-0.97, p = 0.034) after controlling for age, sex, and Charlson Comorbidity Index.

CONCLUSION

ADD prescription rates were relatively low, with a one-year persistence rate of 25 %. Early-ADD use may improve clinical outcomes by reducing hospitalization and in-hospital mortality. These findings provide clinical features of ADD used in real-world settings and highlight the need for adherence to practice standards and strategies to promote ADD persistence among individuals with dementia.

Effect of choline alfoscerate in older adult patients with dementia: an observational study from the claims data of national health insurance

BACKGROUND

Choline alfoscerate, a cholinergic precursor with limited evidence of efficacy in dementia management, has been used for various cognitive impairments in Korea. Partly due to its insurance coverage, this agent appears to incur significant expense for the insurance system. Thus, we aimed to describe choline alfoscerate prescription patterns and analyze their long-term effects in an older adult cohort with dementia.

METHODS

This observational study used the National Health Insurance Service Senior Cohort Dataset. Choline alfoscerate -naïve patients who were diagnosed with dementia between 2003 and 2014 with at least 12 months of follow-up were selected. Time-dependent Cox regression was employed to estimate the association between drug exposure and the risk of treatment failure events.

RESULTS

There were 11,463 eligible participants, of whom approximately 73% were female, and 19% had been exposed to choline alfoscerate. According to the main regression survival analysis, the association between longitudinal choline alfoscerate use and the risk of progression events related to treatment failure was unclear. However, a significant decrease of nearly 20% in the risk of all-cause mortality was associated with choline alfoscerate exposure, and a slight reduction in progression regarding treatment failure was observed with CA use only during the early stages of diagnosis. Age, sex, insurance premiums, several comorbidities and concurrent medications were significantly associated with the probability of the events according to the multivariate models.

CONCLUSIONS

Further analyses are needed to confirm the early-stage and long-term effectiveness of choline alfoscerate in specific populations, which will help in considering its reimbursement.

Prescribing patterns in people living with dementia in the community: A cross-sectional study

OBJECTIVES

To identify the prevalence of and factors associated with medication use in people living with dementia in the community.

METHODS

A cross-sectional study using baseline data from a randomised controlled trial known as the Interdisciplinary Home-bAsed Reablement Program (I-HARP) between 2018 and 2021 in Sydney, Australia. Participants included people with mild-moderate dementia and their carers. Medication use was classified according to the Anatomical Therapeutic Chemical codes, while potentially inappropriate medications (PIMs) were defined using 2019 Beer's Criteria and 2024 Australian list. Logistic regression models were used to identify factors associated with use of medication classes.

RESULTS

A total of 130 people with dementia and their carers were included. Of the people with dementia, 35% were using antidementia medication, 48% psychotropics, 76% PIMs and 65% polypharmacy (≥5 medications). Polypharmacy was associated with the use of psychotropics (adjusted OR [aOR]: 5.09, 95% confidence interval [CI]: 1.94-13.39) and PIMs (aOR: 17.38, 95% CI: 5.12-59.02). Higher education level was associated with lower odds of psychotropic use (aOR: .33, 95% CI: .15-.76), and age over 80 years was associated with lower odds of antidementia medication use (aOR: .29; 95% CI: .12-.72).

CONCLUSIONS

The use of PIMs, psychotropics and polypharmacy were common in this sample of people with dementia living in the community. Associations were seen between participant characteristics and medication use. Future research should focus on reviewing PIMs and polypharmacy in people with dementia living in the community to assess the impact on health outcomes.

Prevalence and correlates of probable rapid eye movement sleep behavior disorder among middle-aged and older adults in a psychiatric outpatient clinic: A cross-sectional survey

OBJECTIVE

Rapid eye movement sleep behavior disorder (RBD) is often underdiagnosed among people living with mental disorders. The present study aimed to investigate the prevalence of probable RBD (pRBD) and its associated factors among middle-aged and older adults in a psychiatric outpatient clinic.

METHODS

We conducted a cross-sectional survey among 2907 people aged 45-80 years who visited the outpatient clinic between March 1 and August 31, 2022 in a psychiatric hospital. A cutoff score ≥5 on the RBD Screening Questionnaire (RBDSQ) was used to indicate the presence of probable RBD (pRBD). Potential factors associated with pRBD were also assessed with a structured checklist. The association between these factors and the presence of pRBD was examined with logistic regression.

RESULTS

The response rate was 64.3 %. Among 1868 respondents [age 58.5 ± 9.6 years, male n = 738 (39.5 %), female n = 1130 (60.5 %)], 15.9 % (95 % CI 14.2-17.6 %) screened positive for pRBD. Occupational exposure to chemicals; positive family history of psychotic disorders; a late start of mental health care; a medical history of autonomic dysfunction; mood problems; and use of antidepressants, hypnotics, and acetylcholinesterase inhibitors were associated with an increased likelihood of having pRBD (P < 0.05 for all).

CONCLUSION

pRBD is common among outpatients with mental disorders, especially in mental disorders due to neurological diseases and physical conditions, mood disorders and anxiety or somatoform disorders. The findings highlight the importance of identifying sleep behavior disorders among people living with mental disorders in clinical practice.

Dementia diagnostic and treatment services in the Western Pacific: challenges, preparedness and opportunities in the face of amyloid-targeting therapies

Here we first review the limited available literature addressing the current landscape of specialist assessment services for dementia and cognitive decline and the preparedness for new amyloid-targeting therapies for Alzheimer's disease across the Western Pacific region. Considering the scarcity of literature, as national representatives of Western Pacific nations we were then guided by the World Health Organization's Global Action Plan on Dementia to provide country-specific reviews. As a whole, we highlight that the existing diverse socioeconomic and cultural landscape across the region poses unique challenges, including varying access to services and marked differences among countries in their preparedness for upcoming amyloid-targeting therapies for Alzheimer's disease. Therefore, there is an urgent call for intergovernmental collaboration and investment across the Western Pacific to ensure that for all nations, citizens living with dementia and cognitive decline have access to effective and equitable methods of diagnosis, treatment and care.

Incremental value of amyloid PET in a tertiary memory clinic setting in China

INTRODUCTION

The objective of this study is to investigate the incremental value of amyloid positron emission tomography (Aβ-PET) in a tertiary memory clinic setting in China.

METHODS

A total of 1073 patients were offered Aβ-PET using 18F-florbetapir. The neurologists determined a suspected etiology (Alzheimer's disease [AD] or non-AD) with a percentage estimate of their confidence and medication prescription both before and after receiving the Aβ-PET results.

RESULTS

After disclosure of the Aβ-PET results, etiological diagnoses changed in 19.3% of patients, and diagnostic confidence increased from 69.3% to 85.6%. Amyloid PET results led to a change of treatment plan in 36.5% of patients. Compared to the late-onset group, the early-onset group had a more frequent change in diagnoses and a higher increase in diagnostic confidence.

DISCUSSION

Aβ-PET has significant impacts on the changes of diagnoses and management in Chinese population. Early-onset cases are more likely to benefit from Aβ-PET than late-onset cases.

HIGHLIGHTS

Amyloid PET contributes to diagnostic changes and its confidence in Chinese patients. Amyloid PET leads to a change of treatment plans in Chinese patients. Early-onset cases are more likely to benefit from amyloid PET than late-onset cases.
