Scoping Review of Randomized Trials With Discontinuation of Medicines in Older Adults. J Am Med Dir Assoc 2022; 23:1926.e11-1926.e35. [PMID: 35850165 DOI: 10.1016/j.jamda.2022.06.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Revised: 05/31/2022] [Accepted: 06/12/2022] [Indexed: 12/15/2022]
Abstract
OBJECTIVES To map the randomized trial evidence describing the feasibility of discontinuing active medications with potential adverse effects in older patients. DESIGN Scoping review with systematic search of PubMed, Embase, and Cochrane Library. SETTING AND PARTICIPANTS Randomized trials investigating discontinuation of a single medicine or medicine class in patients with mean age ≥65 years. METHODS We extracted trial characteristics including study design and assessed bias. As proxies for the "feasibility of discontinuation," we extracted the "dropout rate" and "disease recurrence rate." RESULTS We identified 40 trials investigating discontinuation of symptomatic (n = 26), preventive (n = 6), or both preventive and symptomatic medicines (n = 8) against psychiatric (n = 10), neurologic (n = 9), musculoskeletal (n = 8), cardiovascular (n = 5), respiratory (n = 4), and urologic diseases (n = 4). Five discontinuation designs were used, 75% (30/40) of trials were placebo-controlled, and 48% (19/40) of trials had bias disfavoring discontinuation. The dropout rate was similar between the discontinuation group and the continuation group in 79% of the trials (30/38), whereas disease recurrence was similar in 72% (23/32) of the trials. In 42% (13/31) of trials reporting both dropout rate and disease recurrence rate, the differences between groups were statistically insignificant and less than 10%; these trials investigated discontinuation of cholinesterase inhibitors for Alzheimer's disease in various settings (n = 3), alendronate for osteoporosis (n = 3), glucosamine for osteoarthritis, lithium as adjunct for unipolar depression, statins for cardiovascular disease in patients with limited life expectancy, droxidopa for neurogenic orthostatic hypotension, tamsulosin for lower urinary tract symptoms, sertraline for major depressive episode, and fentanyl patch for low back or osteoarthritis pain. CONCLUSIONS AND IMPLICATIONS We identified 40 randomized trials using a variety of designs investigating discontinuation of both symptomatic and preventive medicines in older patients. Discontinuation of medicines seems feasible for most of the investigated medicines. This scoping review can guide clinical practice and future trials on deprescribing.

Abstract
Patients with dementia can experience hallucinations and delusions because of their underlying neurodegenerative condition, a syndrome known as dementia-related psychosis. Dementia-related psychosis contributes to morbidity and mortality among patients with dementia and increases the burden on caregivers and the health care system. With no pharmacological treatment currently approved in the United States for this condition, patients are often treated off-label with antipsychotics. Though typical and atypical antipsychotics have demonstrated variable to modest efficacy in dementia-related psychosis, serious safety concerns arise with their use. Accordingly, clinical and Centers for Medicare & Medicaid Services guidelines recommend trying antipsychotics only when other therapies have failed and encourage treatment discontinuation of antipsychotics after 4 months to assess whether ongoing therapy is needed. Discontinuation of effective antipsychotic treatment, however, may increase the risk for relapse of symptoms and the associated morbidities that accompany relapse. A randomized medication withdrawal clinical trial design allows assessment of relapse risk after discontinuation and can provide initial information on longer-term safety of therapy for dementia-related psychosis. Given the substantial unmet need in this condition, new, well-tolerated therapies that offer acute and sustained reduction of symptoms while also preventing recurrence of symptoms of psychosis are critically needed.

Abstract
Background Best practice guidelines recommend regular evaluation of antipsychotics in managing behaviours for dementia patients with a view to de-prescribing, given its significant mortality and adverse outcomes (Reus et al. in Am J Psychiatry 173(5):543-546, 2016, Deprescribing Guidelines and Algorithms in https://deprescribing.org/resources/deprescribing-guidelines-algorithms/ , 2019). The relationship between the dose of antipsychotic and the probability of discontinuation remains unknown in hospitalized dementia patients. Objectives This study aims to examine the relationship between high dose antipsychotic (greater than 62 mg chlorpromazine equivalent daily dose) and antipsychotics discontinuation in hospitalized dementia patients. Setting Specialized Dementia Behavioral Health Program in Hamilton, Ontario, Canada. Method A retrospective chart review was completed from August to December of 2019. A univariate logistic regression model was applied to antipsychotic doss (in chlorpromazine equivalent) and antipsychotic discontinuation outcome at 60 days (Narayan and Nishtala in Eur J Clin Pharmacol 73(12):1665-1672, 2017). A multivariant model was used to assess potential confounders, including other psychiatric medication exposure and Medicines Comorbidity Index (Luthra in J Gerontol Geriatr Res 4(260):2, 2015). Regression and dose-response models were utilized to identify the threshold dose (maximum daily dose). Main outcome measures Antipsychotic discontinuation at 60 days after the last dose. Results A total of 42 patients were eligible for outcome analysis. High dose antipsychotic was associated with worse discontinuation outcomes in both unadjusted (odds ratio, 0.09; 95% confidence interval, 0.02-0.37; p < 0.01) and adjusted generalized estimation equation models (odds ratio 0.65; 95% confidence interval, 0.59-0.72; p = 0.01). There were no statistically significant associations between baseline comorbidities (Medicines Comorbidity Index) (p = 0.68), mood stabilizer (p = 0.14), benzodiazepines (p = 0.93) and antidepressant exposure (p = 0.68) with antipsychotic discontinuation. The logistic regression model identified 40.7 mg of quetiapine, 1.7 mg of olanzapine and 0.51 mg of risperidone as the threshold dose, balancing sensitivity and specificity. The dose-response model also identified similar doses of 42 mg of quetiapine, 1.76 mg of olanzapine and 0.53 mg of risperidone. Conclusion The use of high dose antipsychotics is associated with worse discontinuation outcomes in hospitalized dementia patients. Therefore, our results suggest not exceeding a daily dose of 50 mg of quetiapine, 1.75 mg of olanzapine and 0.5 mg of risperidone when used for responsive behaviours and reassess the benefits and risks for each patient regularly.

Abstract
According to the World Alzheimer’s report, dementia was estimated to affect 50 million worldwide in 2018, number expected to increase to more than 150 million within 30 years. Alzheimer’s disease is the most common type of dementia, accounting on its own for 2/3 of all dementia cases. The initial signs and symptoms of Alzheimer’s disease relate to progressive cognitive decline, inexorably progressing until the loss of independence. Neuropsychiatric and behavioral symptoms may occur during the progression of the disease; around 20% of patients without any behavioral symptoms at the diagnosis will experience some of them within 2 years. Consequences are early institutionalization, lower quality of life, of both patients and carers, and more severe cognitive impairment. Treatment options for behavioral symptoms include pharmacological and non-pharmacological approaches. The latter are usually preferred, since antipsychotic therapy is not free from several, and often serious, adverse events. However, behavioral symptoms are not always controllable with non-pharmacological intervention. The psychotropic class of medication more frequently prescribed for behavioral symptoms are atypical antipsychotics; among them, risperidone is the only one licensed for the treatment of aggression, in Europe but not in the USA. On that regard, the use of antipsychotic drugs should be limited, due to the increased risk of mortality, stroke, hallucination, and higher risk of relapse after discontinuation. Some new agents are under evaluation, such as pimavanserin and lumateperone. In this review, we are evaluating the current available pharmacological options to treat behavioral symptoms as well as the forthcoming new agents.

Abstract
Dementia affects all domains of cognition. The relentless progression of the disease after diagnosis is associated with a 98% incidence of neuropsychiatric symptoms (NPS) at some point in the disease, including depression, psychosis, agitation, aggression, apathy, sleep disturbances, and disinhibition. These symptoms can be severe and lead to excess morbidity and mortality. The purpose of this article was to describe current literature on the medication management of NPS of dementia and highlight approaches to and concerns about the pharmacological treatment of NPS in the USA. Guidelines and expert opinion favor nonpharmacologic management of NPS as first-line management. Unfortunately, lack of adequate caregiver training and a high failure rate eventually result in the use of psychotropic agents in patients with dementia. Various psychotropic medications have been studied, although how they should be used in the management of NPS remains unclear. A systematic approach to evaluation, treatment, and monitoring, along with careful documentation and evidenced-based agent and dose selection, is likely to reduce risk and improve patient outcomes. Considerations should be given to the NPS presentation, including type, frequency, and severity, when weighing the risks and benefits of initiating, continuing, or discontinuing psychotropic management. Use of antidepressants, sedative/hypnotics, antipsychotics, and antiepileptic agents should include a clear and documented analysis of risk and benefit in a given patient with dementia.

Abstract
Behavioral and Psychological Symptoms of Dementia (BPSD), present in almost 90% of patients with Alzheimer's Disease (AD), cause extensive impairment leading to reduced independence and inability to complete activities of daily living. Though BPSD includes a wide range of symptoms, such as agitation, aggression, disinhibition, anxiety, depression, apathy, delusions, and hallucinations. Certain BPSD in AD co-present and can be clustered into distinct domains based on their frequency of co-occurrence. As these BPSD are so pervasive in any stages of AD, the disease may be better characterized as a disorder of heterogeneous degenerative symptoms across a number of symptom domains, with the most prominent domain comprising memory and cognitive deficits. Importantly, there are no FDA-approved drugs to treat these BPSD, and new approaches must be considered to develop effective treatments for AD patients. The biogenic monoamine 5-hydroxytryptamine (5-HT), or serotonin, works as both a neurotransmitter and neuromodulator, which has been tied to cognitive decline and multiple BPSD domains. This review summarizes the evidence for specific serotonergic system alterations across some of the well-studied cognitive, behavioral, and psychiatric domains. Though differences in overall serotonergic transmission occur in AD, circuit-specific alterations in individual 5-HT receptors (5-HTRs) are likely linked to the heterogeneous presentation of BPSD in AD.

Abstract
PURPOSE OF REVIEW This review presents the latest developments covered in the literature regarding psychosis in neurodegenerative disorders and discusses possible future research directions. RECENT FINDINGS Recent findings in the field of psychosis and neurodegenerative disorders revolve around four main themes. The first theme is the impact of sex on the expression of psychosis in neurodegenerative disorders. The second theme focuses on the relationship between psychosis and neurodegenerative disease biomarkers. The third concerns how psychotic symptoms in neurodegenerative disorders may share common mechanisms with other primary psychotic disorders such as schizophrenia. Finally, there have been some promising developments in the area of therapeutics to treat dementia-related psychosis involving both established and novel treatments. SUMMARY New findings in the field of neurodegeneration and psychosis parallel new directions in the field of neurodegeneration in general. More specifically, we have seen a shift in focus to issues highlighting the role of sex, biomarkers, translation to other disorders, and therapeutics.

Abstract
Behavioral and psychological symptoms of dementia (BPSD) are highly prevalent and represent a significant burden for patients and their caregivers. Early recognition and management of these symptoms is crucial as they are associated with increased risk of institutionalization, impairments in daily functioning, reduced quality of life, and more rapid progression to severe dementia. This chapter will discuss the pathophysiology, proposed diagnostic criteria, clinical features, and management of BPSD, including apathy, depression, agitation/aggression, psychosis, and sleep disturbances. Apathy and depression are the most common overall, and apathy is associated with high symptom severity likely because of its greater persistence. Symptoms such as agitation, aggression, hallucinations, and delusions may be especially distressing and dangerous to patients and caregivers. Nonpharmacologic management should be considered first-line therapy in most cases due to the modest and inconsistent evidence base for pharmacologic agents and greater risk of harm. However, the judicious use of pharmacologic agents may be warranted when symptoms are dangerous and/or severely distressing.

Abstract
OBJECTIVE The purpose of this study was to identify the association between antipsychotics and mortality in Alzheimer's disease patients. METHODS Using the Taiwan National Health Insurance Research Database, 735 newly diagnosed Alzheimer's disease patients aged over 65 years and receiving antipsychotic treatments, and 735 age, sex, physical comorbidity, and entry year with propensity scores, matched control subjects were enrolled and followed for a 10-year period until the end of 2011. Multivariate Cox proportional hazards regression models were used for analysis. RESULTS The mortality rate was 56% in Alzheimer's disease patients treated with antipsychotics, and 65% in Alzheimer's disease patients not treated with antipsychotics during an average of 5.2 years of follow-up. The use of antipsychotics, typical antipsychotics, and atypical antipsychotics was found to be associated with lower mortality (adjusted hazard ratio=0.66, 95% confidence interval 0.58-0.75; 0.69, 0.60-0.79; 0.56, 0.44-0.71, respectively, all p<0.001). In addition, Alzheimer's disease patients with higher cumulative dose and longer duration of exposure to antipsychotics showed a significantly reduced risk of mortality. Other variables associated with higher risk of mortality included age (adjusted hazard ratio=1.08, 95% confidence interval 1.07-1.09, p<0.001), male gender (1.27, 1.11-1.45, p<0.001), diabetes mellitus (1.30, 1.10-1.54, p<0.01), congestive heart failure (1.54, 1.11-2.12, p<0.01), and stroke (1.23, 1.05-1.44, p<0.01). CONCLUSION The use of antipsychotics was found to be associated with lower mortality in Alzheimer's disease patients. Moreover, dose and duration response effects were also identified.

Abstract
INTRODUCTION Antipsychotics have long been the mainstay of treatment for agitation and psychosis in Alzheimer's disease. Despite their current use successive studies have shown that they only confer a modest benefit which must be balanced against their well-established serious side effects (extrapyramidal symptoms, stroke, accelerated cognitive decline and mortality). Areas covered: This review outlines the current guidance on antipsychotic usage and the evidence of their continued usage against a backdrop of emerging pharmacological treatments and an increasing emphasis on the importance of non-pharmacological interventions. Expert commentary: The current justification for antipsychotic use in the context of the changing landscape of prescribing and provide a view on the most promising alternative candidates to this class of drug are appraised.

Abstract
BACKGROUND Antipsychotic agents are often used to treat neuropsychiatric symptoms (NPS) in people with dementia although there is uncertainty about the effectiveness of their long-term use for this indication and concern that they may cause harm, including higher mortality. When behavioural strategies have failed and treatment with antipsychotic drugs is instituted, regular attempts to withdraw them have been recommended in guidelines. Physicians, nurses and families of older people with dementia may be reluctant to stop antipsychotics, fearing deterioration of NPS.This is an update of a Cochrane Review published in 2013. OBJECTIVES To evaluate whether withdrawal of antipsychotic agents is successful in older people with dementia and NPS in primary care or nursing home settings, to list the different strategies for withdrawal of antipsychotic agents in older participants with dementia and NPS, and to measure the effects of withdrawal of antipsychotic agents on participants' behaviour and assess safety. SEARCH METHODS We searched the Specialized Register of the Cochrane Dementia and Cognitive Improvement Group (ALOIS), theCochrane Library, MEDLINE, Embase, PsycINFO, CINAHL, LILACS, clinical trials registries and grey literature sources up to 11 January 2018. SELECTION CRITERIA We included all randomised, controlled trials comparing an antipsychotic withdrawal strategy to continuation of antipsychotics in people with dementia who had been treated with an antipsychotic drug for at least three months. DATA COLLECTION AND ANALYSIS We used standard methodological procedures according to the Cochrane Handbook for Systematic Reviews of Interventions. We rated the quality of evidence for each outcome using the GRADE approach. MAIN RESULTS We included 10 studies involving 632 participants. One new trial (19 participants) was added for this update.One trial was conducted in a community setting, eight in nursing homes and one in both settings. Different types of antipsychotics at varying doses were discontinued in the studies. Both abrupt and gradual withdrawal schedules were used. Reported data were predominantly from studies at low or unclear risk of bias.We included nine trials with 575 randomised participants that used a proxy outcome for overall success of antipsychotic withdrawal. Pooling data was not possible due to heterogeneity of outcome measures used. Based on assessment of seven studies, discontinuation may make little or no difference to whether or not participants complete the study (low-quality evidence).Two trials included only participants with psychosis, agitation or aggression who had responded to antipsychotic treatment. In these two trials, stopping antipsychotics was associated with a higher risk of leaving the study early due to symptomatic relapse or a shorter time to symptomatic relapse.We found low-quality evidence that discontinuation may make little or no difference to overall NPS, measured using various scales (7 trials, 519 participants). There was some evidence from subgroup analyses in two trials that discontinuation may reduce agitation for participants with less severe NPS at baseline, but may be associated with a worsening of NPS in participants with more severe NPS at baseline.None of the studies assessed withdrawal symptoms. Adverse effects of antipsychotics (such as falls) were not systematically assessed. Low-quality evidence showed that discontinuation may have little or no effect on adverse events (5 trials, 381 participants), quality of life (2 trials, 119 participants), or cognitive function (5 trials, 365 participants).There were insufficient data to determine whether discontinuation of antipsychotics has any effect on mortality (very low-quality evidence). AUTHORS' CONCLUSIONS There is low-quality evidence that antipsychotics may be successfully discontinued in older people with dementia and NPS who have been taking antipsychotics for at least three months, and that discontinuation may have little or no important effect on behavioural and psychological symptoms. This is consistent with the observation that most behavioural complications of dementia are intermittent and often do not persist for longer than three months. Discontinuation may have little or no effect on overall cognitive function. Discontinuation may make no difference to adverse events and quality of life. Based on the trials in this review, we are uncertain whether discontinuation of antipsychotics leads to a decrease in mortality.People with psychosis, aggression or agitation who responded well to long-term antipsychotic drug use, or those with more severe NPS at baseline, may benefit behaviourally from continuation of antipsychotics. Discontinuation may reduce agitation for people with mild NPS at baseline. However, these conclusions are based on few studies or small subgroups and further evidence of benefits and harms associated with withdrawal of antipsychotic is required in people with dementia and mild and severe NPS.The overall conclusions of the review have not changed since 2013 and the number of available trials remains low.

Abstract
Behavioral and psychological symptoms represent common complications in patients with different types of dementia. Predominantly, they comprise psychosis, agitation and mood disorders, disinhibited behavior, impairment of the sleep and wakefulness rhythm, wandering, perseveration, pathological collecting, or shouting. Their appearance is related to more rapid progression of the disease, earlier institutionalization, use of physical restraints, and higher risk of mortality. Consequently, appearance of behavioral and psychological symptoms of dementia leads to higher costs of care provided and greater distress for caregivers. Clinical guidelines recommend nonpharmacological approaches as the first choice in the treatment of behavioral and psychological symptoms. Pharmacological therapy should be initiated only if the symptoms were not the result of somatic causes, did not respond to nonpharmacological interventions, or were not caused by the prior medication. Acetylcholinesterase inhibitors, memantine, antipsychotic drugs, antidepressants, mood stabilizers, and benzodiazepines are used. This review summarizes the current findings about the efficacy and safety of the treatment of the neuropsychiatric symptoms in dementias with psychopharmaceuticals. Recommendations for treatment with antipsychotics for this indication are described in detail as this drug group is prescribed most often and, at the same time, is related to the highest risk of adverse effects and increased mortality.
