Psychotropic medications and risk for falls among community-dwelling frail older people: an observational study

Intrinsic capacity and recent falls in adults 80 years and older living in the community: results from the ilSIRENTE Study

BACKGROUND

Falls in older adults significantly impact overall health and healthcare costs. Intrinsic capacity (IC) reflects functional reserve and is an indicator of healthy aging.

AIMS

To explore the association between IC and recent falls (≤ 90 days) in community-dwelling octogenarians from the Aging and Longevity in the Sirente geographic area (IlSIRENTE) study.

METHODS

The Minimum Data Set for Home Care (MDS-HC) and supplementary questionnaires and tests were used to assess the five IC domains: locomotion, cognition, vitality, psychology, and sensory. Scores in each domain were rescaled using the percent of maximum possible score method and averaged to obtain an overall IC score (range 0-100).

RESULTS

The study included 319 participants (mean age 85.5 ± 4.8 years, 67.1% women). Mean IC score was 80.5 ± 14.2. The optimal IC score cut-off for predicting the two-year risk of incident loss of at least one activity of daily living (ADL) was determined and validated in a subset of 240 individuals without ADL disability at baseline (mean age 84.7 ± 4.4 years, 67.1% women). Participants were then stratified into low (< 77.6) and high (≥ 77.6) IC categories. Those with high IC (63.9%) were younger, more often males, and had lower prevalence of recent falls, disability, multimorbidity, and polypharmacy. Logistic regression models including IC as a continuous variable revealed a significant association between higher IC and lower odds of falls. This association was significant in the unadjusted (odds ratio [OR] 0.96, 95% confidence interval [CI] 0.94-0.98, p < 0.001), age- and sex-adjusted (OR 0.96, 95% CI 0.94-0.98, p < 0.001), and fully adjusted models (OR 0.96, 95% CI 0.93-0.99, p = 0.003). When considering IC as a categorical variable, unadjusted logistic regression showed a strong association between high IC and lower odds of falls (OR 0.31, 95% CI 0.16-0.60, p < 0.001). This association remained significant in both the age- and sex-adjusted (OR 0.30, 95% CI 0.15-0.59, p < 0.001) and fully adjusted models (OR 0.33, 95% CI 0.16-0.82, p = 0.007). The locomotion domain was independently associated with falls in the unadjusted (OR 0.98, 95% CI 0.97-0.99, p < 0.001), age- and sex-adjusted (OR 0.97, 95% CI 0.96-0.99, p < 0.001), and fully adjusted model (OR 0.98, 95% CI 0.96-0.99, p < 0.001).

DISCUSSION

This is the first study using an MDS-HC-derived instrument to assess IC. Individuals with higher IC were less likely to report recent falls, with locomotion being an independently associated domain.

CONCLUSIONS

Lower IC is linked to increased odds of falls. Interventions to maintain and improve IC, especially the locomotion domain, may reduce fall risk in community-dwelling octogenarians.

Comparative analysis of psychiatric medications and their association with falls and fractures: A systematic review and network meta-analysis

An association between psychiatric medications and falls and fractures in people taking them has been demonstrated, but which class or medication leads to the greatest risk of falls or fractures should be further investigated. The aim of this study was to compare and rank the magnitude of risk of falls and fractures due to different psychiatric medications. Eight databases were searched for this meta-analysis and evaluated using a frequency-based network meta-analysis. The results included a total of 28 papers with 14 medications from 5 major classes, involving 3,467,314 patients. The results showed that atypical antipsychotics were the class of medications with the highest risk of falls, and typical antipsychotics were the class of medications with the highest risk of resulting in fractures. Quetiapine ranked first in the category of 13 medications associated with risk of falls, and class Z drugs ranked first in the category of 6 medications associated with risk of fractures. The available evidence suggests that atypical antipsychotics and typical antipsychotics may be the drugs with the highest risk of falls and fractures, respectively. Quetiapine may be the medication with the highest risk of falls, and class Z drugs may be the medication with the highest risk of fractures.

Exploring Predictive Factors for Potentially Avoidable Emergency Department Transfers: Findings From the FINE Study

OBJECTIVES

To assess the prevalence of potentially avoidable transfers (PAT) and identify factors associated with these transfers to emergency departments (EDs) among nursing home (NH) residents.

DESIGN

This is a secondary outcome analysis of the FINE study, a multicenter observational study collecting data on NH residents, NH settings, and contextual factors of ED transfers.

SETTINGS AND PARTICIPANTS

NHs in the former Midi-Pyrénées region of the southwest of France (n = 312); a total of 1037 NH residents who experienced ED transfers (n = 1017) between January 2016 and December 2016.

METHODS

The analysis included resident baseline characteristics and NH and transfer decision-making characteristics. An expert group categorized the transfer status as either PAT or unavoidable. Multivariable analysis using a mixed logistic model, accounting for intra-NH correlation, was conducted to assess factors independently associated with PAT.

RESULTS

Among 1017 included transfers, 87.02% (n = 885) were identified as PAT and 12.98% (n = 132) unavoidable transfers. Multivariable analysis revealed that the following patient-related factors were associated with a likely high rate of PAT: usual behavior disturbances before transfer, including productive trouble (OR 2.04, 95% CI 1.25-3.33; P = .0044) and unusual symptom of falling during the week preceding the transfer (OR 4.55, 95% CI 1.76-11.82; P = .0019). On the other hand, distance between ED and NH (OR 0.98, 95% CI 0.97-0.998; P = .0231), NH staff trained in palliative care in the last 3 years (OR 0.52, 95% CI 0.29-0.95; P = .0324), the impossibility of direct hospitalization to an appropriate unit (OR 0.54, 95% CI 0.34-0.87; P = .0117), and the resident Charlson Comorbidity Index (OR 0.90, 95% CI 0.82-0.99; P = .0369) were associated with a lower probability of PAT.

CONCLUSION AND IMPLICATIONS

Transfers from NHs to hospital EDs were frequently potentially avoidable, meaning that there are still significant opportunities to reduce PAT. Our findings may help to specifically identify interventions that should be targeted at both NH and resident levels.

Benzodiazepine Initiation and the Risk of Falls or Fall-Related Injuries in Older Adults Following Acute Ischemic Stroke

Background

Benzodiazepine use in older adults following acute ischemic stroke (AIS) is common, yet short-term safety concerning falls or fall-related injuries remains unexplored.

Methods

We emulated a hypothetical randomized trial of benzodiazepine use during the acute post stroke recovery period to assess incidence of falls or fall related injuries in older adults. Using linked data from the Get With the Guidelines Registry and Mass General Brigham's electronic health records, we selected patients aged 65 and older admitted for Acute Ischemic Stroke (AIS) between 2014 and 2021 with no documented prior stroke and no benzodiazepine prescriptions in the previous 3 months. Potential for immortal-time and confounding biases was addressed via separate inverse-probability weighting strategies.

Results

The study included 495 patients who initiated inpatient benzodiazepines within three days of admission and 2,564 who did not. After standardization, the estimated 10-day risk of falls or fall-related injuries was 694 events per 1000 (95% confidence interval CI: 676-709) for the benzodiazepine initiation strategy and 584 events per 1000 (95% CI: 575-595) for the non-initiation strategy. Subgroup analyses showed risk differences of 142 events per 1000 (95% CI: 111-165) and 85 events per 1000 (95% CI: 64-107) for patients aged 65 to 74 years and for those aged 75 years or older, respectively. Risk differences were 187 events per 1000 (95% CI: 159-206) for patients with minor (NIHSS≤ 4) AIS and 32 events per 1000 (95% CI: 10-58) for those with moderate-to-severe AIS.

Conclusions

Initiating inpatient benzodiazepines within three days of AIS is associated with an elevated 10-day risk of falls or fall-related injuries, particularly for patients aged 65 to 74 years and for those with minor strokes. This underscores the need for caution with benzodiazepines, especially among individuals likely to be ambulatory during the acute and sub-acute post-stroke period.

Original Research: What Health Care Staff Who Experienced Assisted Patient Falls Can Teach Us: Implications for Fall and Fall Injury Risk

PURPOSE

This quality improvement project had three aims: to identify common assisted falls scenarios, describe staff members' experiences with and risk perceptions of such falls, and explore factors that influenced their perceptions. The overarching goal was to gain useful insight for the development of assisted fall-related strategies and policies.

METHODS

In the fall of 2020, 16 staff members from 13 health care facilities were purposively recruited and interviewed. Transcript summaries of these interviews, along with secondary narrative data from employee and patient injury databases, were analyzed using thematic content analysis.

RESULTS

According to staff members' accounts, assisted falls most commonly took place in patient rooms or bathrooms when patients were ambulating or transferring. The interviewees described assisting falls by grabbing or holding the patient or by using their own body to brace or steady the patient. Interview and secondary narrative data noted various injuries that occurred during assisted fall events. These injuries most often involved the lower back (among staff) and the legs (among patients). Most interviewees perceived that using proper body mechanics would prevent injury.

CONCLUSIONS

Interviewees' experiences with assisted falls indicate areas of improvement for fall prevention. The perception that using proper body mechanics will protect staff from injury may be a misconception. Although the literature reports mixed findings concerning whether staff should assist patient falls, this project's results led us to conclude that there is no safe way to physically assist a falling patient without risk of staff injury.

Observational Prospective Study to Determine the Efficacy of 'Non-Slip Socks' vs. 'Adequate Footwear' Regarding the Number of Falls Observed among Admitted Patients

BACKGROUND

Fall prevention is an important indicator of the quality of patient care. Prevention includes the use of adequate footwear. Our objective is to determine the differences in the number of falls between patients with "adequate footwear" and "non slip socks", and their associated consequences, to support their use in the prevention of falls among hospitalized patients.

METHODS

This is an observational prospective study on inpatient falls. Patient characteristics, fall circumstances, and injuries were collected through Clinical Report Forms, a review of fall reports, and medical records. Admitted patients over 18 years old were recruited from Geriatric and Internal Medicine Units over a brief period of 3 months.

RESULTS

A total of 158 hospitalized patients were recruited. In total, 77 patients (48.73%) were assigned to the non-slip socks group, and 81 (51.27%) were assigned to the adequate footwear group. There were 21 falls during the study period, all of which were experienced by the adequate footwear group (p < 0.0001). The mean age of the patients who fell was 83.14 (range 60-100) years old. The most frequent reasons for admission among the patients who fell were COVID-19 infection (19%) and oncological complications (19%). Overall, 61.9% of patients had a high risk of falling. Most falls (76.1%) occurred in patient rooms, and most of these occurred while wandering around. The most frequent reason for falls was slipping (14/21). For 16 of 21 patients, falls did not have immediate consequences, while 5 had contusions and 1 suffered a wound. Nobody needed to be admitted to the ER or suffered external hemorrhages or loss of consciousness.

CONCLUSIONS

Non-slip socks represent an adequate alternative to well-fitting rubber-soled footwear. It seems that non-slip socks could prevent falls among hospitalized patients; nevertheless, further studies are necessary to clarify their role in preventing hospital falls and reducing injury rates.

Differences in fall-related characteristics across cognitive disorders

Approximately 40-60% of falls in the elderly lead to injuries, resulting in disability and loss of independence. Despite the higher prevalence of falls and morbidity rates in cognitively impaired individuals, most fall risk assessments fail to account for mental status. In addition, successful fall prevention programmes in cognitively normal adults have generally failed in patients with cognitive impairment. Identifying the role of pathological aging on fall characteristics can improve the sensitivity and specificity of fall prevention approaches. This literature review provides a thorough investigation into fall prevalence and fall risk factors, the accuracy of fall risk assessments, and the efficacy of fall prevention strategies in individuals with diverse cognitive profiles. We show that fall-related characteristics differ between cognitive disorders and fall risk assessment tools as well as fall prevention strategies should critically consider each patient's cognitive status to facilitate the identification of fallers at an earlier stage and support clinical decision-making.

Spatio-Temporal Gait Parameters in Association with Medications and Risk of Falls in the Elderly

Purpose

The aim of this study was to analyze factors affecting spatio-temporal gait parameters in elderly people of both genders and different ages with different risks of fall, fall history, and medications.

Patients and Methods

A total of 210 community-dwelling older adults (156 females, 54 males; mean age 72.84±6.26 years) participated in this study. To assess the risk of falls, the Downton Fall Risk Index was used. An additional question about medication intake (all prescribed drugs) was asked. To assess the spatio-temporal gait parameters, the Zebris FDM platform was used. Gait parameters and Downton Fall Risk Index, stratified by participants' history of falls, multiple medication use (0/1/2+), gender, age, and medication categories, were statistically analyzed using the Mann-Whitney U-test and Kruskal-Wallis test.

Results

When comparing different medication categories, a Downton Fall Risk Index score indicating a high risk of falls was observed in the psychotropic medication category (3.56±1.67). A gait velocity suggesting a higher risk of falls (≤3.60 km/h) was observed in the psychotropic (2.85±1.09 km/h) and diabetes (2.80±0.81 km/h) medication categories, in the age groups 70-79 years (3.30±0.89 km/h) and 80+ years (2.67±0.88 km/h), and in participants using two or more medications (3.04±0.93 km/h).

Conclusion

The results of this study confirm previous observations and show that higher age and multiple medication negatively affect the gait, and that the higher risk of falls is associated with psychotropic and diabetes medication use. These results provide important information for future fall preventive programs for the elderly that would be especially beneficial for elderly people taking psychotropic and diabetes medication.

Less Well-Known Consequences of the Long-Term Use of Opioid Analgesics: A Comprehensive Literature Review

BACKGROUND

The adverse effects of short-term opioid analgesics are well known and acknowledged; however, the spectrum of the sequelae of long-term use seems less clear. Some effects may remain undetected but still have the potential to cause harm and reduce patients' quality of life.

OBJECTIVE

To review the literature on the adverse effects of long-term opioid therapy.

METHODS

We performed a quasi-systematic search, analyzing articles published in the MEDLINE database between January 2000 and March 2021 that identified adverse effects of opioids used for chronic pain treatment.

RESULTS

Growing evidence indicates that there are multiple serious adverse effects of opioid treatment. Long-term opioid use may have significant effects on the endocrine, immune, cardiovascular, respiratory, gastrointestinal, and neural systems. Studies show that long-term opioid treatment increases the risk of fractures, infections, cardiovascular complications, sleep-disordered breathing, bowel dysfunction, overdose, and mortality. Opioids may potentially affect cancer development. Most consequences of the long-term use of opioids have been identified in studies of patients with non-malignant pain.

CONCLUSION

Studies indicate that long-term use of opioids increases the risk of drug-related events in a significant number of patients. Clinicians should be aware of these complications associated with prescribing opioids, discuss them with patients, prevent complications, if possible, and diagnose them early and manage adequately. More human studies are needed to assess the risk, including trials with individual opioids, because they have different adverse effect profiles.

Associated mortality risk of atypical antipsychotic medication in individuals with dementia

BACKGROUND

Antipsychotic medications such as risperidone, olanzapine and aripiprazole are used to treat psychological and behavioural symptoms among dementia patients. Current evidence indicate prescription rates for antipsychotics vary and wider consensus to evaluate clinical epidemiological outcomes is limited.

AIM

To investigate the potential impact of atypical antipsychotics on the mortality of patients with dementia.

METHODS

A retrospective clinical cohort study was developed to review United Kingdom Clinical Record Interactive Search system based data between January 1, 2013 to December 31, 2017. A descriptive statistical method was used to analyse the data. Mini Mental State Examination (MMSE) scores were used to assess the severity and stage of disease progression. A cox proportional hazards model was developed to evaluate the relationship between survival following diagnosis and other variables.

RESULTS

A total of 1692 patients were identified using natural language processing of which, 587 were prescribed olanzapine, quetiapine or risperidone (common group) whilst 893 (control group) were not prescribed any antipsychotics. Patients prescribed olanzapine showed an increased risk of death [hazard ratio (HR) = 1.32; 95% confidence interval (CI): 1.08-1.60; P < 0.01], as did those with risperidone (HR = 1.35; 95%CI: 1.18-1.54; P < 0.001). Patients prescribed quetiapine showed no significant association (HR = 1.09; 95%CI: 0.90-1.34; P = 0.38). Factors associated with a lower risk of death were: High MMSE score at diagnosis (HR = 0.72; 95%CI: 0.62-0.83; P < 0.001), identifying as female (HR = 0.73; 95%CI: 0.64-0.82; P < 0.001), and being of a White-British ethnic group (HR = 0.82; 95%CI: 0.72-0.94; P < 0.01).

CONCLUSION

A significant mortality risk was identified among those prescribed olanzapine and risperidone which contradicts previous findings although the study designs used were different. Comprehensive research should be conducted to better assess clinical epidemiological outcomes associated with diagnosis and therapies to improve clinical management of these patients.

Psychotropic drug use among older people with major neurocognitive disorder: a cross-sectional study based on Swedish national registries

AIM

Psychotropic medications include many drugs that may be inappropriate for older individuals with cognitive impairment. In Sweden, many people become registered in the Swedish Dementia Registry when they are diagnosed with major neurocognitive disorder (NCD). In this study, we aim to describe psychotropic drug use and associated factors among older Swedish people with major NCD.

METHODS

This study included 38,251 people ≥ 65 years from the Swedish registry for cognitive/dementia disorders diagnosed during 2007-2017. Drug use was defined as one or more filled prescription(s) recorded in the Swedish Prescribed Drug Register during 1 July to 31 December 2017. Associations between psychotropics and age, sex, diagnosis date, Mini-Mental State Examination score and major NCD subtype were analysed through multiple logistic regression.

RESULTS

We found that 12.0% of the individuals filled at least one prescription for antipsychotics, 22.0% for anxiolytics, 23.0% for sedatives or hypnotics, 43.2% for antidepressants and 56.7% for antidementia drugs. In brief, psychotropic use was associated with female sex, higher age, longer time since diagnosis and specific subtypes of major NCD; the strongest association was found between antipsychotics and Lewy body dementia (odds ratio 2.40, 95% confidence interval 2.04-2.82).

CONCLUSION

Psychotropic drugs were frequently dispensed among older Swedish people with major NCD. The use of antipsychotics and medications with sedative properties warrants concern, especially among those with Lewy body dementia who are severely sensitive to antipsychotics. A more restrictive prescribing pattern regarding these medications might reduce the risk of drug-related problems in this vulnerable group of people.

The Effects of Osteoporotic and Non-osteoporotic Medications on Fracture Risk and Bone Mineral Density

Osteoporosis is a highly prevalent bone disease affecting more than 37.5 million individuals in the European Union (EU) and the  United States of America (USA). It is characterized by low bone mineral density (BMD), impaired bone quality, and loss of structural and biomechanical properties, resulting in reduced bone strength. An increase in morbidity and mortality is seen in patients with osteoporosis, caused by the approximately 3.5 million new osteoporotic fractures occurring every year in the EU. Currently, different medications are available for the treatment of osteoporosis, including anti-resorptive and osteoanabolic medications. Bisphosphonates, which belong to the anti-resorptive medications, are the standard treatment for osteoporosis based on their positive effects on bone, long-term experience, and low costs. However, not only medications used for the treatment of osteoporosis can affect bone: several other medications are suggested to have an effect on bone as well, especially on fracture risk and BMD. Knowledge about the positive and negative effects of different medications on both fracture risk and BMD is important, as it can contribute to an improvement in osteoporosis prevention and treatment in general, and, even more importantly, to the individual's health. In this review, we therefore discuss the effects of both osteoporotic and non-osteoporotic medications on fracture risk and BMD. In addition, we discuss the underlying mechanisms of action.

Factors associated with Emergency Medical Dispatcher request and residents' inappropriate transfers from Nursing Homes to Emergency Department

PURPOSE

In the last decades, the amount of emergency department (ED) transfers of nursing home (NH) residents has disproportionally increased in western countries. The main role of emergency medical dispatcher (EMD) among this population is to refer residents to EDs in the most appropriate way. The aim of this study was to assess risk factors of inappropriate transfers from NH to ED after EMD request.

METHODS

This research was a secondary analysis of a prospective observational multicenter study carried out in 17 EDs entitled FINE aimed to assess potentially inappropriate transfer prevalence among this population. Inappropriate transfers were determined in the FINE study threw a standardized approach by a unique expert team.

RESULTS

Overall, 572/1037 (55.2%) of residents were transferred to the ED after an EMD's decision. Among them, 92/572 (16.1%) transfers was defined as inappropriate. The average age was 87.3 years old (SD = 0.3). The main reason for ED transfer were falls (217/572, 37.9%). In multivariate analysis, the presence of a Special Care Unit in NH was significantly associated with a high rate of inappropriate transfer (OR 1.78; 95 CI [1.07-2.93]; p = 0.02) whereas a medical examination by a general practitioner before the transfer (OR 0.55; 95 CI [0.33-0.83]; p = 0.02) and a prompt access to psychiatric advice (OR 0.54; 95 CI [0.33-0.84]; p = 0.007) were associated with a low rate of potentially inappropriate transfer.

CONCLUSION

Promoting onsite medical assessment and partnership thanks to available geriatrician's advice may help the emergency medical dispatcher to improve the appropriateness of residents' transfer from Nursing Home to the emergency department.

Herbal Medicine for Behavioral and Psychological Symptoms of Dementia: A Systematic Review and Meta-Analysis

Background: Dementia is a global health concern, causing serious health and socioeconomic burdens with population aging. The associated symptoms of dementia, called behavioral and psychological symptoms of dementia (BPSD), are factors contributing to the socioeconomic burden of dementia. Recently, herbal medicine (HM) has attracted attention as a potential complementary therapy for BPSD. Therefore, this systematic review was aimed at analyzing the effectiveness (or efficacy), safety, and research status of HM in BPSD management through a comprehensive review.

Methods: Thirteen electronic databases were searched comprehensively. Related clinical studies published until December 28, 2020, were collected. The methodological quality was evaluated using tools such as the Cochrane Collaboration’s risk of bias tool according to the study design. The effectiveness (or efficacy) was analyzed for randomized controlled trials (RCTs) only, and when sufficient homogeneity was assured, effect estimates were presented as mean difference (MD) and risk ratio (RR), with 95% confidence interval (CIs), through a meta-analysis.

Results: A total of 52 clinical studies, including 36 RCTs, were included in this review. As an adjunctive therapy, HM showed statistically significant benefits in BPSD severity assessed by the Behavior Pathology in Alzheimer’s Disease Rating Scale (combined with psychotropic drugs: MD = −3.48, 95% CI: −3.96 to −2.99; with anti-dementia drugs: MD = −2.81, 95% CI: −3.17 to −2.45) and Neuropsychiatric Inventory (with anti-dementia drugs: MD = −3.23, 95% CI: −4.06 to −2.40). Adverse events were significantly less frequent in the HM group (RR = 0.50; 95% CI: 0.28 to 0.88). However, the methodological quality of the RCTs included in this systematic review was not optimal overall.

Conclusion: According to the findings of this review, HM may be associated with additional benefits in BPSD treatment, particularly when used as an adjunct to conventional medications, including psychotropic and anti-dementia drugs. However, considering the methodological quality of the included RCTs, this clinical evidence is not robust. Nevertheless, dementia is a global health concern, and considering the limitations of conventional psychotropic drugs for BPSD, a major cause of the disease burden, HM appears to be a promising complementary therapy that warrants further research.

Kratom exposures among older adults reported to U.S. poison centers, 2014-2019

BACKGROUND

In recent years, use of the herbal supplement kratom has increased in the United States. The reasons for use include pain relief, particularly as a substitute for opioids.

OBJECTIVES

To describe epidemiologic trends in kratom-related exposures among older adults reported to U.S. poison centers.

DESIGN

Retrospective analysis of American Association of Poison Control Center's National Poison Data System (NPDS).

SETTING

Data from all U.S. poison centers from 2014 to 2019 were examined.

PARTICIPANTS

Kratom exposure cases involving adults aged 18 and older. Kratom cases were identified by product and NPDS generic codes. Non-human and information-only calls were excluded. Data were examined for all calls for exposures among adults, with a focus on older adults aged 60-69 years and above 70 years.

MEASUREMENTS

Descriptive analyses were used to characterize individual demographic, exposure information, clinical effects, and medical outcomes associated with kratom exposures among older adults. Comparisons across age groups (18-59, 60-69, and 70+ years) were made using Fisher's exact tests.

RESULTS

Among 3484 kratom-related exposures reported between 2014 and 2019, 4.6% (n = 162) were among adults over 60 years. The number of kratom-related exposures increased over time. Most cases originated with calls from healthcare facilities (81.1%) and involved kratom as a single ingestant (63.0%). The reason for most ingestions was intentional (74.5%). One in five exposures among adults aged 70 and older involved an adverse reaction (e.g., drug interaction; 21.9%), compared with 12.3% among ages 60-69 and 9.6% among ages 18-59 years. Neurological and cardiovascular clinical effects were observed. Twenty-three deaths were observed among older adults.

CONCLUSION

Healthcare providers and older adult patients should be aware of the potential risks of kratom use, including medication interactions and falls. When reviewing medication lists, providers should query this population for all medications and substances being used, especially in people being treated for pain.

Herbal medicine for behavioral and psychological symptoms of dementia: A protocol for systematic review

BACKGROUND

Dementia is becoming a major public health problem worldwide with the aging of the world's population. Behavioral and psychological symptoms of dementia (BPSD), associated symptoms of dementia, not only predicts the poor prognosis of patients with dementia, but is also a major factor causing the care burden on caregivers, especially informal caregivers. For BPSD management, an alternative to existing psychotropic drugs is needed, given the benefit-harm ratio. Therefore, in this systematic review, we will evaluate the effectiveness and safety of herbal medicine for BPSD.

METHODS AND ANALYSIS

Thirteen electronic databases will be comprehensively searched. Clinical studies reporting the efficacy (or effectiveness) and safety of herbal medicines in BSPD management published from their inception to December 2020 will be included. The primary outcome will be BPSD symptoms assessed by the validated tool. Moreover, total effective rate, daily living activities and quality of life of patients, burden and quality of life of caregiver, placement in a long-term care facility from home, and safety data will be regarded as the secondary outcome. Two independent researchers will perform the study selection, data extraction, and quality assessment process. To assess the methodological quality of the included studies, validated tools according to its design, such as the Cochrane Collaboration's risk of bias tool will be used. To perform meta-analysis, RevMan version 5.3 will be used, with mean differences for continuous outcomes and risk ratio for binary outcomes, and 95% confidence intervals. According to the heterogeneity and number of included studies, a fixed- or random-effects model will be used.

Prevalence and Associates of Fear of Falling among Community-Dwelling Older Adults

OBJECTIVES

We aimed to study the prevalence of fear of falling (FOF), and its association with physical performance, functionality, frailty, sarcopenia, and a variety of geriatric syndromes including cognitive impairment, depression, quality of life and hearing.

DESIGN

Retrospective, cross-sectional study.

SETTING

Community-dwelling older adults applied to the geriatric outpatient clinic of a university hospital.

PARTICIPANTS

A total of 1021community-dwelling older adults >= 60 years of age applying to the geriatric outpatient clinic of a university hospital.

MEASUREMENTS

We screened for falls and FOF by single close-ended questions. We performed screening and assessment of probable sarcopenia by SARC-F test and handgrip strength evaluation according to EWGSOP2. We used timed up and go test (TUG), usual gait speed (UGS) for physical performance, and Katz- activities of daily living (ADL) and Lawton-Brody instrumental activities of daily living (IADL) for functional evaluation. We screened anxiety with the Generalized Anxiety Disorder-7 scale.

RESULTS

The prevalence of FOF was 44.6% and falls, 37.7%. Prevalence of FOF in sarcopenia screening positive participants was 30.1%; in probable sarcopenic (35/20 kg) participants, 43.9%; in those with undernutrition, 45.7%; in fallers, 51.1%; in females, 80.4%; and in prefrail/frail was 74.7% Multivariate regression analyses revealed that female sex (OR=4.1, 95%CI= 2.0-8.4, p<0.001), anxiety (OR=2.7, 95%CI= 1.1-6.5, p=0.03) and ADL limitation (OR=2.5, 95%CI= 1.03-6.3, p=0.04) were independent associates of FOF.

CONCLUSION

FOF accompanied by fall experience or not is prevalent in community-dwelling older adults. It is associated with anxiety and ADL limitations apart from the female sex.

Systematic causality mapping of factors leading to accidental falls of older adults

Introduction

According to WHO’s statistical evidence, accidental falls are the second leading causes of death worldwide. This systematic literature review and meta-analysis aims to provide a holistic view of risk factors and unfold the missing or less addressed but crucial factors that lead to accidental falls of the older adults. It also intends to profile the risk factors at different levels, which helps exhibit the level of consistency relationship between various risk factors and falls.

Study design

Systematic literature review.

Methods

A systematic review on the risk factors leading to accidental falls of older adults by retrieving English journal papers published starting from 1980 was conducted on April 2018. A method of literature synthesis and causal mapping was adopted to aggregate those fall-leading factors into macro variables and a coherent causal tracing network was thereby built, which can reflect not only the causal relationship of various macro variables but also the “consistency of agreement” between macro variables and falls of the older adults.

Results

A hypothesized causal relationship diagram of 19 aggregated macro variables and their 31 causal relationship suggested by the observational evidences is demonstrated. The consistency relationship between macro variables and elderly accidental fall are summarized and demonstrated. Our analysis reveals that “Time”, “Season” and “Weather” are three less-studied factors in the literature. In our comprehensive analysis, our study also indicates neglected countries and senior populations such as Africa and Oceania, which requires more attention from the research community and global funding agencies. It is found that major quantitative tools focus on the traditional statistical analysis.

Conclusion

With the accelerated aging and increase of longevity worldwide, national and regional policies, and public health programs to provide adequate care services for the older people are crucially needed in both industrialized and developing countries. Evidences identified in the research are valuable inputs for policy design and decision makers of different stakeholders and prevention design of risk factors for falls in the older adults. The categorization of research methods in different literature also suggests that more quantitative approaches including simulation, optimization in operational research, and maybe machine learning are needed to enrich the research paradigm. We suggest researchers to consider using our presented causal map and the way of building it and explore the possibility of extending this framework to uncover more research topics in health-related research.

[Evaluation of drug interactions in patients treated for a lung or digestive cancer]

INTRODUCTION

Cancer patients are particularly at risk for drug interactions. However, in oncology, this risk has not been studied in depth in France. The main objective of this study was to describe the proportion of drug interactions in patients with lung or digestive cancer.

METHODS

The drug prescriptions of 93 patients were analyzed from may 27th, 2019 to July 07th, 2019 using two software programs (Thériaque™ and DDI Predictor™) in oncology patients hospitalized in our comprehensive cancer center.

RESULTS

Of the 88 patients included in the study, 544 drug interactions were identified, in 66 patients (75.0%, 95% CI: 64.6-83.6). For 20/88 patients (22.7% CI: 14.5-32.9) a non-recommended combination or a theoretical contraindication was reported. Etoposide was the anticancer molecule most involved in combinations that are contraindicated or not recommended. No combinations defined as not recommended or contraindicated were observed in any of the 49 patients treated with chemotherapy during their hospitalization. The most common toxicities were alertness and metabolic disorders, including hyperkalemia. The use of three or more drugs was a risk factor for drug interactions (83 vs. 23%, P<0.001).

CONCLUSION

Drug interactions remain a major concern in cancer hospitalized patients. It is important to continue and strengthen the collaboration between physicians and pharmacists in order to better prevent their occurrence.

Sedative Load in Community-Dwelling Older Adults with Mild-Moderate Alzheimer's Disease: Longitudinal Relationships with Adverse Events, Delirium and Falls

BACKGROUND

Older adults are frequently prescribed medications with sedative effects, which are associated with numerous adverse consequences. However, the prevalence and longitudinal associations of sedative medication use in community-dwelling older adults with mild-moderate Alzheimer's disease (AD) has not been explored to date.

OBJECTIVES

Our objective was to assess the prevalence of sedative medication use in community-dwelling older adults with mild-moderate AD and examine the longitudinal association between sedative medication use and adverse events (AEs).

METHODS

The association between baseline sedative load (SL) and AEs, unscheduled healthcare utilisation, delirium and falls was assessed in older adults with mild-moderate AD over 18 months using secondary analysis of NILVAD trial data (collected from 2014 to 2016). Baseline medication use was assessed, and the SL model was applied to each participant's medication individually. The SL model classifies medications into one of four categories: (1) primary sedatives, (2) medications with a sedating component or prominent side effect, (3) medications with sedation as a potential adverse reaction and (4) all other medications with no known sedative side effects. Medications in group 1 were assigned an SL score of 2, those in group 2 were assigned an SL score of 1, and those in categories 3 and 4 an SL score of 0. SL scores for each medication participants were taking were summed and the total SL calculated as an arithmetic sum of individual medications score. A total SL score ≥ 3 was classed as high. Statistical analysis was conducted using Poisson regression and mixed-effects linear regression, with adjustment for important clinical covariates. We also assessed the impact of SL on dementia progression and cognitive decline.

RESULTS

Over half (55.7% [284/510]) of those with mild-moderate AD (age 72.8 ± 8.3 years, 61.9% female) were prescribed a regular medication with sedation as a primary effect or prominent side effect, with 22.2% (113/510) having a high SL (≥ 3). The most common medications contributing to SL were antidepressants, antipsychotics, anxiolytics and hypnotics. Over 18 months, increasing baseline SL was associated with incident AEs (incidence rate ratio [IRR] 1.15; 95% confidence interval [CI] 1.11-1.19; p < 0.001), serious AEs (IRR 1.23; 95% CI 1.11-1.36; p < 0.001) and unscheduled general practitioner visits (IRR 1.23; 95% CI 1.13-1.34; p < 0.001). Further, increasing SL was associated with a greater likelihood of incident delirium (IRR 1.30; 95% CI 1.11-1.53; p < 0.001) and falls (IRR 1.20; 95% CI 1.03-1.42; p = 0.02). Associations persisted after robust covariate adjustment. SL was not associated with accelerated cognitive decline or AD progression.

CONCLUSIONS

In the current study, over half of older adults with mild-moderate AD were prescribed at least one drug with a sedative effect, and a significant minority had a high SL. Increasing baseline SL was associated with a greater likelihood of incident AEs, delirium and falls, highlighting the need for optimal prescribing in this potentially vulnerable cohort.

[Association Suvorexant and Ramelteon Use with the Risk of Falling: A Retrospective Case-control Study]

Sedative hypnotics are among the classes of drugs reported to influence falls. However, the effects of the sedative hypnotic drugs, suvorexant and ramelteon, on falls are not well known. Therefore, we conducted this retrospective case-control study to examine the association of the use of these two sedative hypnotics with the risk of falls. Conducted at the Sapporo Medical University Hospital in Japan, our study included 360 patients with fall incidents and 819 randomly selected control patients. Patients in the fall group were significantly older with a lower body mass index, and had a history of falls, disabilities in activities of daily living, cognitive impairment, and delirium. Monovariate analysis revealed that patients in the fall group frequently used ramelteon [odds ratio (OR) 2.38, 95% confidence interval (CI): 1.49-3.81, p<0.001], but rarely used suvorexant (OR 0.66, 95% CI: 0.29-1.39, p=0.317), compared with control patients. Furthermore, multivariate analysis revealed that ramelteon use did not increase the risk of falls (adjusted OR 1.43, 95% CI: 0.82-2.48, p=0.207), whereas suvorexant use significantly decreased the risk of falls (adjusted OR 0.32, 95% CI: 0.13-0.76, p=0.009). Although ramelteon tends to be used in patients at a high risk of falls, it may not increase the risk of falls. In contrast, the use of suvorexant may reduce the risk of falls.

The long-term but not short-term use of benzodiazepine impairs motoric function and upregulates amyloid β in part through the suppression of translocator protein

Many elderly American women use CNS depressant benzodiazepine (BZD) to ameliorate anxiety or insomnia. However, the chronic use of BZD (cBZD) is prevalent, causing adverse effects of BZD that include movement deficit. We previously reported that cBZD upregulates neurotoxic amyloid β42 (Aβ42) and downregulates neuroprotective translocator protein (TSPO) in the cerebellum, the brain area of movement and balance. The aim of the current study is two-fold: 1) to determine a direct effect of TSPO (inhibition) on cBZD-induced Aβ42 and Aβ-associated molecules; Aβ-producing-protein presenilin-1 (PS1) and Aβ-degrading-enzyme neprilysin and 2) to determine whether Aβ42 upregulation and motoric deficit occur upon a long-term (cBZD) rather than a short-term BZD (sBZD) treatment. Old female mice received BZD (lorazepam) for 20 days (cBZD) or 3 days (sBZD) with or without prototype TSPO ligand PK11195 and were tested for motoric performance for 3 days using Rotarod. ELISA was conducted to measure Aβ42 level and neprilysin activity in cerebellum. RT-PCR and immunoblot were conducted to measure the mRNA and protein levels of TSPO, PS1, and neprilysin. cBZD treatment decreased TSPO and neprilysin but increased Aβ42 accompanied by motoric deficit. Chronic PK11195 treatment acted as a TSPO inhibitor by suppressing TSPO expression and mimicked or exacerbated the effects of cBZD on all parameters measured except for PS1. None of the molecular and behavioral changes induced by cBZD were reproduced by sBZD treatment. These data suggest that cBZD upregulates Aβ42 and downregulates neprilysin in part through TSPO inhibition, the mechanisms distinct from sBZD, collectively contributing to motoric deficit.

Effectiveness of Best Practice Alerts for Potentially Inappropriate Medication Orders in Older Adults in the Ambulatory Setting

INTRODUCTION

Information is limited about the effectiveness of best practice alerts (BPAs) for potentially inappropriate medications (PIMs) in improving clinical outcomes in older adults.

OBJECTIVE

To assess clinical outcomes of 11 BPAs for PIMs in older adults in the ambulatory setting.

METHODS

A retrospective cohort study was conducted at an integrated health care delivery system with computerized provider order entry. Patients aged 65 years and older were included if they had a BPA triggered when a prescriber attempted to order a sedating PIM in the ambulatory setting. Patients were categorized into dispensed and nondispensed groups if they did and did not, respectively, have the study PIM for which the BPA was triggered dispensed within 30 days of the alert. Rates of fall, fracture, or other injury and cognitive impairment were measured during 180-day follow-up.

RESULTS

A total of 2704 patients were included: 1373 (50.8%) and 1331 (49.2%) in the dispensed and nondispensed groups, respectively. The dispensed group had a lower unadjusted rate of fall/fracture/injury (3.4% vs 5.3%, p = 0.019), but this difference was attenuated with multivariable adjustment (adjusted odds ratio = 0.77, 95% confidence interval = 0.51-1.13). There was no difference in the rate of cognitive impairment between groups (4.6% vs 4.4%, adjusted odds ratio = 1.40, 95% confidence interval = 0.95-2.05).

CONCLUSION

No association was identified between PIM dispensing after a prescriber was alerted with a BPA and reduced rates of falls/fractures/injuries and cognitive impairment.

Fall-Risk-Increasing Drugs: A Systematic Review and Meta-Analysis: II. Psychotropics

BACKGROUND AND OBJECTIVE

Falls are a major public health problem in older adults. Earlier studies showed that psychotropic medication use increases the risk of falls. The aim of this study is to update the current knowledge by providing a comprehensive systematic review and meta-analysis on psychotropic medication use and falls in older adults.

METHODS AND DESIGN

This study is a systematic review and meta-analysis. A search was conducted in Medline, PsycINFO, and Embase. Key search concepts were "falls," "aged," "medication," and "causality." Studies were included that investigated psychotropics (antipsychotics, antidepressants, anxiolytics, sedatives, and hypnotics) as risk factors for falls in participants ≥60 years of age or participants with a mean age of ≥70 years. Meta-analyses were performed using generic inverse variance method pooling unadjusted and adjusted odds ratio (OR) estimates separately.

RESULTS

In total, 248 studies met the inclusion criteria for qualitative synthesis. Meta-analyses using adjusted data showed the following pooled ORs: antipsychotics 1.54 [95% confidence interval (CI) 1.28-1.85], antidepressants 1.57 (95% Cl 1.43-1.74), tricyclic antidepressants 1.41 (95% CI 1.07-1.86), selective serotonin reuptake inhibitors 2.02 (95% CI 1.85-2.20), benzodiazepines 1.42 (95%, CI 1.22-1.65), long-acting benzodiazepines 1.81 (95%, CI 1.05-3.16), and short-acting benzodiazepines 1.27 (95%, CI 1.04-1.56) Most of the meta-analyses resulted in substantial heterogeneity that did not disappear after stratification for population and healthcare setting.

CONCLUSIONS

Antipsychotics, antidepressants, and benzodiazepines are consistently associated with a higher risk of falls. It is unclear whether specific subgroups such as short-acting benzodiazepines and selective serotonin reuptake inhibitors are safer in terms of fall risk. Prescription bias could not be accounted for. Future studies need to address pharmacologic subgroups as fall risk may differ depending on specific medication properties. Precise and uniform classification of target medication (Anatomical Therapeutic Chemical Classification) is essential for valid comparisons between studies.

Association Between Incident Exposure to Benzodiazepines in Early Pregnancy and Risk of Spontaneous Abortion

IMPORTANCE

Benzodiazepine use in early pregnancy is associated with spontaneous abortion (SA). However, to date, the association between specific benzodiazepine agent exposure and the risk of SA has not been examined.

OBJECTIVE

To quantify the risk of SA associated with gestational benzodiazepine incident use by drug class, duration of action, and specific benzodiazepine agent.

DESIGN, SETTING, AND PARTICIPANTS

This nested case-control study within the Quebec Pregnancy Cohort, Montreal, Quebec, Canada, includes all pregnancies covered by the Quebec Prescription Drug Insurance Plan from January 1, 1998, through December 31, 2015. Each case was randomly matched with up to 5 controls. Statistical analysis was performed from January 1, 1998, through December 31, 2015.

EXPOSURES

Benzodiazepine exposure was defined as 1 or more filled prescriptions between the first day of the last menstrual period and the index date (the calendar date of the SA diagnosis). Benzodiazepine exposure was categorized by overall use, long- or short-acting benzodiazepine, and specific benzodiazepine agents.

MAIN OUTCOMES AND MEASURES

Spontaneous abortion defined as a pregnancy loss between the beginning of the sixth week of gestation and the 19th completed week of gestation. Conditional logistic regression models were used to calculate odds ratios (OR) and 95% CIs.

RESULTS

Of the 442 066 pregnancies included in the Quebec Pregnancy Cohort, 27 149 (6.1%) ended with SA, with a mean (SD) maternal age of 24.2 (6.5) years. Among pregnancies ending with SA, 375 (1.4%) were among women exposed to benzodiazepines in early pregnancy compared with 788 (0.6%) of the 134 305 matched control pregnancies (crude OR, 2.39; 95% CI, 2.10-2.73). Adjusting for potential confounders, including maternal mood and anxiety disorders before pregnancy, and compared with nonuse, benzodiazepine exposure in early pregnancy was associated with an increased risk of SA (adjusted OR, 1.85; 95% CI, 1.61-2.12). The risk was similar among pregnancies exposed to short-acting (284 exposed cases; adjusted OR, 1.81; 95% CI, 1.55-2.12) and long-acting (98 exposed cases; adjusted OR, 1.73; 95% CI, 1.31-2.28) benzodiazepines during early pregnancy. All benzodiazepine agents were independently associated with an increased risk of SA (range of adjusted ORs, 1.13-3.43).

CONCLUSIONS AND RELEVANCE

An increased risk of SA was observed among early pregnancies with incident exposure to short- and long-acting benzodiazepines and all specific benzodiazepine agents during early pregnancy. Insomnia, anxiety, and mood disorders are prevalent during pregnancy; clinicians should carefully evaluate the risk-benefit ratio of prescribing benzodiazepines in early pregnancy since alternative nonpharmacologic treatments exist.

The Association Between Central Nervous System-Active Medication Use and Fall-Related Injury in Community-Dwelling Older Adults with Dementia

OBJECTIVES

To examine the association between central nervous system (CNS)-active medication use and the risk of fall-related injury in community-dwelling older adults following dementia onset. Further, to evaluate increased risk at higher doses or with a greater number of CNS-active medication classes.

METHODS

Participants included community-dwelling older adults aged 65 years and older with a dementia diagnosis participating in the Adult Changes in Thought Study. From automated pharmacy data, a time-varying composite measure of CNS-active medication use was created. Central nervous system-active medication use was classified as current (use within prior 30 days), recent (prior 31-90 days), past (prior 91-365 days), and nonuse (no exposure in prior year). For current users, standardized daily doses (SDDs) were calculated for each CNS-active medication and summed across medications, and the number of CNS-active medication classes used was also measured. The outcome was fall-related injury based on emergency department, inpatient, and outpatient International Classification of Diseases, Ninth Revision (ICD-9) and external cause of injury (E) codes.

RESULTS

Among 793 subjects, 303 fall-related injuries occurred over a mean follow-up of 3.7 years (2907 total person-years). Relative to nonuse, fall risk was significantly higher for current use (adjusted hazard ratio [HR] 1.59, 95% confidence internal [CI] 1.19-2.12) but not for past or recent use. Among current users, increased risk was seen across SDD levels: HRs (95% CI): 1.77 (1.19-2.62), 1.79 (1.25-2.56), and 1.35 (0.96-1.92) for less than 1 SDD, 1 to less than 2 SDDs, and 2 or more SDDs, respectively (trend test, p=0.14). A trend was seen for increasing risk with a greater number of CNS-active medication classes; however, this was not statistically significant (trend test, p=0.084).

CONCLUSIONS

Current use of CNS-active medications was associated with fall-related injury in community-dwelling older adults followed from time of dementia onset, with increased risk even with use of low doses.

A Literature Review of Psychotropic Medications and Alcohol as Risk Factors for Falls in Community Dwelling Older Adults

Psychotropic medications and alcohol are potential risk factors for falls in older adults. However, there has been no appraisal of the literature on whether these medications, both singly and in combination with alcohol, are associated with falls in community dwelling older adults (those aged 60 years and older living independently without care). Four databases (PubMed, EMBASE, CINAHL and SCOPUS) and the grey literature (i.e. WHO, Public Health Agency of Canada) were searched using the following terms: benzodiazepine, anti-psychotics, anti-depressants, anti-epileptic, lithium, memantine, anti-hypertensives: drug or medication, aged or elderly or older adult or senior, accidental falls or falls or falling, and alcohol. Studies were included if (1) they were primary studies; (2) included community dwelling persons aged 60 years and older; (3) alcohol use was an independent variable; (4) studied medications of interest; (5) falls was the outcome variable; and (6) published in English. Articles published until July 2018 were included. The search yielded 29 studies. The findings show that both benzodiazepines and antidepressants (particularly SSRIs) are associated with fall risk while antipsychotics, anti-hypertensives, anti-epileptics and alcohol are not. No statements were made about lithium or memantine due to a lack of research studies. Future studies with adequate power to detect significant associations between psychotropic medications and falls are needed, especially among individual benzodiazepine and antidepressant medications.

Evaluating the Impact of Music & Memory's Personalized Music and Tablet Engagement Program in Wisconsin Assisted Living Communities: Pilot Study

BACKGROUND

Individuals with Alzheimer disease or related dementia represent a significant and growing segment of the older adult (aged 65 years and above) population. In addition to physical health concerns, including comorbid medical conditions, these individuals often exhibit behavioral and psychological symptoms of dementia (BPSD). The presence of BPSD in long-term care residential facilities can disrupt resident's care and impact staff. Nonpharmacological interventions such as personalized music and tablet engagement maintain cognitive function, improve quality of life (QOL), and mitigate BPSD for older adults with dementia. Evidence of the impact of such interventions in assisted living communities (ALCs) is needed for widespread adoption and sustainment of these technologies.

OBJECTIVE

The aim of this study was to assess the impact of Music & Memory's personalized music and tablet engagement (PMATE) program on QOL, agitation, and medication use for residents living in 6 Wisconsin ALCs.

METHODS

The data collected were on the utilization of iPods and iPads by the residents. Residents' outcomes were assessed using the Pittsburgh Agitation Scale, the Quality of Life in Late Stage Dementia scale, and self-reported medication use. A mixed-methods approach was utilized to examine the impact of the PMATE program on these outcomes. Descriptive statistics were calculated. A paired t test explored changes in residents' QOL. A 1-way analysis of variance was utilized to examine changes in resident's agitation and QOL based on the resident's utilization of the PMATE program. Qualitative interviews were conducted with the individuals responsible for PMATE implementation in the ALC. Residents excluded from the analysis were those who passed away, were discharged, or refused to participate.

RESULTS

A total of 5 apps, based on average times used by residents, were identified. In all, 4 of the 5 apps were rated as being useful to promote residents' engagement. PMATE utilization was not associated with changes in the residents' agitation levels or antipsychotic medication use over time. Over a 3-month period, the change in residents' QOL was significant (P=.047), and the differences across ALCs were also significant (F₂₅=3.76, P=.02). High utilizers of the PMATE program (>2500 min over 3 months) showed greater improvements in QOL as compared with low utilizers (a change of -5.90 points vs an increase of 0.43 points). The difference was significant (P=.03). Similar significant findings were found between the high- and midutilizers.

CONCLUSIONS

The study is one of the first to explore the impact of Music & Memory's PMATE program on residents living in ALCs. Findings suggest that higher utilization over time improves residents' QOL. However, a more comprehensive study with improved data collection efforts across multiple ALCs is needed to confirm these preliminary findings.

Willingness to Change Medications Linked to Increased Fall Risk: A Comparison between Age Groups

OBJECTIVE

To describe and compare two age groups' knowledge of medications linked to falls and willingness to change these medications to reduce their fall risk.

METHOD

We analyzed data from community-dwelling adults age 55 and older (n = 1812): 855 adults aged 55 to 64 years and 957 older adults (65 and older) who participated in the 2016 summer wave of the ConsumerStyles survey, an annual Web-based survey. The data are weighted to match the US Current Population Survey proportions on nine US Census Bureau demographic characteristics.

MEASUREMENTS

Survey respondents were asked about medication use, knowledge of side effects, their willingness to change their medications to reduce fall risk, communication in the previous year about fall risk with their healthcare provider, and their comfort in discussing fall risk with their healthcare provider. All data were weighted to match the 2016 population estimates. Descriptive statistics and χ² (p ≤ .05) were used to identify differences between the two age groups.

RESULTS

About one-fifth of all respondents reported using at least one class of medication that increases fall risk. Older adults were less likely to report using medications for mood or sadness, less likely to report knowing the side effects of pain medications, and more willing to change their sleep medications compared with their younger counterparts. Among all respondents using these medication classes, less than one-third knew the potential fall-related side effects. However, most of them expressed willingness to change their medication if advised by their healthcare provider.

CONCLUSION

Most older adults were unaware of potential fall risks associated with medications prescribed to address pain, difficulty sleeping, mood or sadness, and anxiety- or nervousness-related health issues. However, most were willing to change their medication if recommended by a healthcare provider. J Am Geriatr Soc 67:527-533, 2019.

Sedative-hypnotic initiation and renewal at discharge in hospitalized older patients: an observational study

Background

Sedative-hypnotics (SHs) are widely used in France but there are no available data addressing their prescription specifically in hospitalized older patients. The objective is thus to determine the cumulative incidence of sedative-hypnotic (SH) medications initialized during a hospital stay of older patients, the proportion of SH renewal at discharge among these patients and to study associated risk factors.

Methods

We conducted a retrospective observational study in six internal medicine units and six acute geriatric units in eight hospitals (France). We included 1194 inpatients aged 65 and older without SH medications prior to hospitalization. Data were obtained from patients’ electronic pharmaceutical records. Primary outcome was the cumulative incidence of SH initiation in the study units. Secondary outcomes were the proportion of SH renewal at discharge and risk factors for SH initiation and renewal at discharge (patient characteristics, hospital organization). A Cox regression model was used to study risk factors for SH initiation. A mixed effects logistic regression was used to study risk factors for SH renewal at discharge.

Results

SH initiation occurred in 21.5% of participants 20 days after admission. SH renewal at discharge occurred in 38.7% of patients who had initiated it during their stay and were discharged home and in 56.0% of patients discharged to rehabilitation facilities. Neither patients’ characteristics nor hospital organization patterns was associated with SH initiation. SH initiation after the first six days after admission was associated with a lower risk of SH renewal in patients discharged to rehabilitation facilities (OR = 0.19, 95% CI: [0.04–0.80]).

Conclusions

Hospitalization is a period at risk for SH initiation. The implementation of interventions promoting good use of SHs is thus of first importance in hospitals. Specific attention should be paid to patients discharged to rehabilitation facilities.

Chronic benzodiazepine suppresses translocator protein and elevates amyloid β in mice

Benzodiazepine (BZD) is a commonly prescribed anxiolytic and sedation aid medication, especially in elderly women. However, long-term use of BZD provokes adverse nontherapeutic effects that include movement deficit. Here, we investigated motoric deficit and molecular changes in cerebellum associated with the chronic use of BZD (cBZD) in female mice. We measured neuroprotective translocator protein (TSPO), neurotoxic amyloid β (Aβ), Aβ-producing presenilin-1 (PS1), and Aβ-degrading neprilysin. We also tested whether cBZD treatment damages mitochondrial membranes by measuring mitochondrial membrane swelling and mitochondrial respiration. Young and old mice received BZD (lorazepam) for 20 days, were tested for motoric function using Rotarod, and then euthanized to collect cerebellum. The major methods were immunoblot and RT-PCR for TSPO, PS1, and neprilysin expressions; ELISA for Aβ level; spectrometry for mitochondrial membrane swelling; XF-respirometry for mitochondrial respiration. cBZD-treated old mice showed poorer motoric function than old control or young cBZD-treated mice. Old mice treated with cBZD showed a decrease in TSPO and neprilysin and an increase in Aβ and PS1 production compared to old control mice. Old cBZD-mice also showed an increase in mitochondrial membrane swelling and a decrease in mitochondrial respiration. These data suggest that cBZD exacerbates motoric aging in a manner that involves diminished TSPO, elevated Aβ, and mitochondrial damage.

Anticholinergic and sedative drug burden in community-dwelling older people: a national database study

OBJECTIVES

The Drug Burden Index (DBI) tool quantifies individual exposure to anticholinergic and sedative medications. The DBI has been internationally validated against adverse health outcomes in older people. DBI exposure has not been reported in the Irish older population. This study aimed to: (1) develop a list of drugs with clinically significant anticholinergic and/or sedative effects (DBI medications) relevant to Ireland; (2) examine, using the DBI formula, the prevalence of exposure to DBI medications in Irish older people and (3) explore patient factors associated DBI exposure.

DESIGN

A cross-sectional national pharmacy claims database study.

SETTING

Community setting using the General Medical Services (GMS) scheme pharmacy claims database maintained by the Health Service Executive Primary Care Reimbursement Services.

PARTICIPANTS

Irish older individuals (aged ≥65 years) enrolled in the GMS scheme and dispensed at least one prescription item in 2016 (n=428 516).

MAIN OUTCOME MEASURES

Prevalence of exposure to DBI medications and patient factors associated with DBI exposure.

RESULTS

282 874 (66%) of the GMS population aged ≥65 years were exposed to at least one DBI medication in 2016. Prevalence of exposure to DBI medications was significantly higher in females than males (females 71.6% vs males 58.7%, adjusted OR 1.65, 95% CI 1.63 to 1.68). Prevalence of DBI exposure increased progressively with the number of chronic drugs used, rising from 42.7% of those prescribed 0-4 chronic drugs to 95.4% of those on ≥12 chronic drugs (adjusted OR 27.8, 95% CI 26.7 to 29.0). The most frequently used DBI medications were codeine/paracetamol combination products (20.1% of patients), tramadol (11.5%), zopiclone (9.5%), zolpidem (8.5%), pregabalin (7.9%) and alprazolam (7.8%).

CONCLUSIONS

The majority of older people in Ireland are exposed to medications with anticholinergic and/or sedative effects, particularly females and those with multiple comorbidities. The high use of low-dose codeine/paracetamol combination products, Z-drugs and benzodiazepines, suggests there are opportunities for deprescribing.

Association between frailty and its individual components with the risk of falls in patients with schizophrenia spectrum disorders

Frailty is common among older people who carry an increased risk for poor outcomes, including falls, physical disabilities, infections, and mortality. However, the prevalence of frailty and the prognostic influence of frailty status are poorly understood in adults with schizophrenia. The present study aimed to assess the predictive ability of frailty and its individual components for the risk of falls in patients with chronic schizophrenia. Frailty status was assessed at baseline by using Fried frailty criteria after the enrollment of 561 patients with chronic schizophrenia. The patients were followed up for 18 months, and the outcome of the study was the incidence of falls. The mean age of the patients was 53.8 years, and a total of 35.3% were females. One-quarter (25.3%) of patients received typical antipsychotics. The prevalence of frailty was 10.2% at baseline. During follow-up, 40 patients (7.1%) experienced falls. Frailty status was associated with increased susceptibility to falling with an unadjusted hazard ratio of 5.27 (95% confidence interval: 2.75-10.10) and a hazard ratio of 4.65 (95% confidence interval: 1.88-11.54) after multivariate adjustment. Among the components of frailty, the most significant association was observed between low physical activity and falls (p < 0.05). In conclusion, frailty is highly prevalent in patients with chronic schizophrenia and is associated with the risk of adverse clinical events. Further studies are needed to explore the mechanisms underlying the relationship between schizophrenia and frailty in an attempt to develop an appropriate treatment plan for improving clinical outcomes for these patients.

Benzodiazepines Withdrawal: Initial Outcomes and Long-Term Impact on Falls in a French Nursing Home

Long-term use of benzodiazepines (BZDs) is known to induce tolerance and dependence, and increase the risk of falls-related injuries in older adults. We present a study carried out in a French nursing home that concerns the implementation of a BZD withdrawal program reassessed at one year. BZD deprescription was achieved by gradual cessation of doses. A secondary benefit of this program was assessed by comparing the number of falls among residents before and after withdrawal. The number of falls was recorded over a six-month period prior to the onset of withdrawal (T1) and then over a six-month period after reassessment at one year (T2). At the beginning, 31 (28.7%) of the patients were under BZD. Total deprescription was obtained for 11 patients. The number of falls per patient over the T1 period was not different between the two groups (future non-withdrawn and withdrawn patients in BZD): 2.1 ± 1.3 and 2.3 ± 0.6 falls per resident, respectively. Conversely, the number of falls per patient was significantly decreased in the population completely withdrawn in BZD between the T1 and T2 periods (2.3 ± 0.6 vs. 0.5 ± 0.2 falls, p = 0.01). The results show that BZD deprescription, through a gradual reduction of doses, is possible to achieve.

Use of benzodiazepines and cognitive performance in primary care patients with first cognitive complaints

ABSTRACTThe aim of the present study is to investigate the impact of benzodiazepine use on cognitive performance in primary care patients with first cognitive complaints. The association between the exposition to benzodiazepines (short and long half-life) and cognitive performance, evaluated through the Mini Mental State Examination (MMSE), was tested through analysis of the covariance and logistic regression models. Within the 4,249 participants (mean age 77.0 ± 8.2, 66.4% women), 732 (17%) were on benzodiazepines. When compared with non-users, short- and long-acting benzodiazepine users presented overlapping adjusted MMSE mean scores (respectively, mean MMSE score: 25.3, 95%CI 25.2-25.5; 25.4, 95%CI 25.1-25.7, and 25.9, 95%CI 25.3-26.4; p = 0.156). When tested according to the logistical regression model, after adjusting for potential confounders, no association was found between short and long acting benzodiazepine use and a MMSE < 24 (respectively, OR 0.9, 95%CI 0.7-1.2; OR 0.8, 95%CI 0.7-1.3) as compared with non-users. In conclusion, according to the results of our study, benzodiazepine use seems not to impact on cognitive performance- as assessed with the MMSE- of primary care patients referring to GPs for first cognitive complaints.

Z-drugs and risk for falls and fractures in older adults-a systematic review and meta-analysis

Objective

zolpidem, zopiclone, eszopiclone and zaleplon, also known as 'Z-drugs', are commonly used as alternatives to benzodiazepines (BZDs) to treat insomnia. Z-drugs are often perceived as safer than BZDs. We conducted a systematic review and meta-analysis evaluating the association between Z-drugs and fracutres, falls and injuries.

Methods

a systematic review was performed using MEDLINE, EMBASE and ClinicalTials.gov. Pooled effect-sizes were calculated comparing Z-drugs users with non-users, using fixed and random-effect models with corresponding 95% confidence of intervals (CI).

Results

we identified 14 eligible studies reporting on the association between Z-drugs and outcomes of interest. Z-Drugs were associated with a statistically significant increased risk for fractures, with evidence of considerable heterogeneity (OR = 1.63; 95% CI: 1.42-1.87; I2 = 90%; n = 830,877). Likewise, there was a trend suggesting a 2-fold increase in the odds for falls, however, this result was not statistically significant and there was evidence of considerable heterogeneity (OR = 2.40; 95% CI: 0.92-6.27; I2 = 95%; n = 19,505). In an analysis assessing the risk for injuries following exposure to zolpidem we found a statistically significant increased risk of injuries, with no evidence of heterogeneity (OR = 2.05; CI 95%: 1.95-2.15; I2 = 0; n = 160,502). Results were similar in sensitivity analyses, including analyses restricted to studies of high-quality, studies with control groups suffering from insomnia, and with specific Z-drugs.

Conclusion

our results indicate that Z-drugs are associated with an increased risk for fractures, and suggest a possible increased risk for falls and injuries as well. However, studies included were observational and susceptible to confounding. Physicians should consider these potential risks before prescribing these medications in older adults.

A systematic review of regulatory and educational interventions to reduce the burden associated with the prescriptions of sedative-hypnotics in adults treated for sleep disorders

BACKGROUND

The burden of Sedative-Hypnotics (SHs) has been known since the 1980s. Yet, their consumption remains high. A systematic review of the literature should help to assess efficient interventions to improve the appropriate use of SHs in sleep disorders.

OBJECTIVES

To identify and assess regulatory and educational interventions designed to improve the appropriate use of SHs for insomnia treatment.

METHODS

We conducted a systematic review of the literature according to PRISMA guidelines. A systematic search covering the period 1980-2015 was carried out in Medline, Web of Science, Embase and PsycInfo. We included studies reporting the implementation of regulatory or educational strategies directed towards patients and/or healthcare professionals to improve the appropriate use of SHs to treat insomnia in the community, hospitals and nursing homes.

RESULTS

Thirty-one studies were included: 23 assessed educational interventions (recommendations by mail/email, computer alerts, meetings, mass media campaigns, prescription profile), 8 assessed regulatory interventions (prescription rule restriction, end of reimbursement). The most recent was implemented in 2009. Restrictive prescription rules were effective to reduce the consumption of targeted SHs but led to a switch to other non-recommended SHs. Among educational interventions, only 3 studies out of 7 reported positive results of mono-faceted interventions; whereas, 13 out of the 16 multi-faceted interventions were reported as efficient: particularly, the active involvement of healthcare professionals and patients and the spread of information through mass media were successful. The risk of bias was high for 24 studies (mainly due to the design), moderate for 3 studies and weak for 4 studies.

CONCLUSION

Educational multifaceted studies are presented as the most efficient. But further better designed studies are needed to make evidence-based results more generalizable.

Research of falls risk of taking central nervous system drugs in oncology inpatients

This study aimed to analyze the medication use and related falls risk of central nervous system(CNS) drugs in oncology inpatients, explore the association between CNS drugs and falls. In this study, we enrolled inpatients, hospitalized in the oncology department of the Teaching Hospital of Chengdu University of Traditional Chinese Medicine, from March 2013 to October 2015. All inpatients were divided into two groups: taking-CNS drugs group (treatment group) and non CNS drugs group (control group). The falls risk between two groups were being compared and analyzed. Results showed that a total of 768 inpatients were enrolled in this study; 401 of them were males and 367 were females; the average age was 47.9±5.8 year-old. Of them, 129 were taking CNS drugs, while 639 were not. In the treatment group, the number of fall patients was 39, at an incidence rate of 30.23%; of the 39 fall patients, 3 suffered fractures, and 1 suffered an intracranialhemorrhage; while in the control group, the incidence of falls totaled at 45, at an incidence rate of 7.04%; 4 of the patients suffered fractures. The difference of incidence rate between two groups had statistical significance (P＜ 0.01). The incidence rate of falls in the treatment group was 4.29 times that in the control group. By the further analysis of CNS drugs, results implied that hypnotics, sedatives, selective serotonin reuptake inhibitors (no patient taking tricyclic antidepressants in this study), opioids, antiepileptics and antipsychotics had relationship with falls (OR>1). Our finding indicates that oncology inpatients have a higher risk of falls resulting from taking CNS drugs. Therefore, it is necessary to build up a systemic mechanism of nursing safety management on preventing falls of oncology inpatients, to improve nursing quality, and reduce the risk of falls.

High prevalence of prescription of psychotropic drugs for older patients in a general hospital

BACKGROUND

Many elderly patients receive psychotropic drugs. Treatment with psychotropic agents is associated with serious side effects including an increased risk of falls and fractures. Several psychotropic drugs are considered potentially inappropriate for treatment of the elderly.

METHODS

A retrospective chart review was conducted covering all patients aged ≥ 65 years who were admitted to Evangelisches Krankenhaus Göttingen-Weende between 01/01/2013 and 03/31/2013. Psychotropic drugs reviewed for included benzodiazepines, Z-drugs, antidepressants and neuroleptics, but not drugs for sedation during artificial ventilation or pre-medication before surgery. Potentially inappropriate drugs were identified according to the PRISCUS list. To assess which factors were associated with the administration of psychotropic drugs, univariate and multivariable logistic regression analyses were performed.

RESULTS

The charts of 2130 patients (1231 women) were analyzed. 53.9% of all patients received at least one psychotropic medication (29.5% benzodiazepines, 12.6% Z-drugs, 22.2% antidepressants, 11.9% neuroleptics). The mean number of psychotropic drugs prescribed per patient with at least one prescription was 1.6. Patients treated in the geriatric department most often received antidepressants (45.0%), neuroleptics (20.6%) and Z-drugs (27.5%). Benzodiazepines and Z-drugs were prescribed mostly as medication on demand (77.7% of benzodiazepines, 73.9% of Z-drugs). Surgical patients most frequently received benzodiazepines (37.1%). Nearly one-third of all patients ≥ 65 years was treated with at least one potentially inappropriate psychotropic medication. The mean number of potentially inappropriate psychotropic medications per patient with at least one psychotropic prescription was 0.69. The percentage of patients with potentially inappropriate psychotropic medication was highest in the surgical departments (74.1%). Female gender (adjusted OR 1.36; 95% CI 1.14 to 1.63), stay in the Department of Geriatrics (2.69; 2.01 to 3.60) or the interdisciplinary intensive care unit (1.87; 1.33 to 2.64) and age ≥ 85 years (1.33; 1.10 to 1.60) were associated with psychotropic drug treatment.

CONCLUSIONS

A high percentage of patients aged ≥ 65 years received psychotropic drugs. The chance that a potentially inappropriate psychotropic drug would be administered was highest in the surgical departments. Antidepressants, neuroleptics and Z-drugs were used surprisingly often in geriatric medicine. Educational strategies could reduce the use of psychotropic drugs and the prescription of potentially inappropriate medications.

An evaluation of medication appropriateness and frailty among residents of aged care homes in Malaysia: A cross-sectional study

Aging is significantly associated with the development of comorbid chronic conditions. These conditions indicate the use of multiple medications, and are often warranted by clinical guidelines. The aim of the present study was to evaluate medication appropriateness and frailty among Malaysian aged care home residents with chronic disease. The participants were 202 elderly (≥65 years) individuals, a cross-sectional sample from 17 aged care homes. After ethics approval, each participant was interviewed to collect data on sociodemographics, frailty status (Groningen Frailty Indicator [GFI]), medication appropriateness (Medication Appropriateness Index (MAI), the 2015 Beers' criteria (Potentially Inappropriate Medication [PIM]), and 2014 STOPP criteria (Potentially Inappropriate Prescribing [PIP]). The findings show that 81% (n = 164) and 42% (n = 85) were taking medications for cardiovascular and central nervous system-related conditions, respectively, and 34% were using medications for diabetes (n = 69). Each participant had a mean of 2.9 ± 1.5 chronic diseases, with an average GFI score of 6.4 ± 3.6. More than three-quarters of the participants (76%) were frail and polypharmacy was a factor in nearly half (48%); 41% and 36% were prescribed at least one PIP and PIM, respectively, whereas the average MAI score was 0.6 (range: 0-6). The number of medications used per participant correlated significantly and positively (0.21, P = .002) with GFI score. These findings reinforce the need for participants of aged care homes to receive periodic medication review aimed at minimizing morbidity associated with inappropriate pharmacotherapy.

Pre-operative predictors of post-operative falls in people undergoing total hip and knee replacement surgery: a prospective study

INTRODUCTION

Pain and disability often persist following hip (THR) and knee replacement (TKR) surgery predisposing patients to increased risk of falling. This study identified pre-operative predictors for post-operative falls in TKR and THR patients, and the incidence and circumstances of falls in the 12 months post-surgery.

MATERIALS AND METHODS

A survey was undertaken of patients before THR and TKR, and was repeated 12 months post-operation. The survey included (1) medical history and medications usage, (2) pain and function, (3) health-related and physical activity and (4) fear of falls and history of falls questionnaires. Patients were classified as 'fallers' (≥1 fall) or 'non-fallers' based on prospectively documented falls in the 12 months post-surgery. Binary logistic regression was conducted to identify independent pre-operative predictors of incident falls status.

RESULTS

Eighty-two of the 243 participants (33.7%) reported ≥1 fall in the 12 months post-operatively [60 (34.1%) patients following TKR and 22 (32.8%) following THR]. The logistic regression model was statistically significant, χ ² = 24.731, p < 0.001, the model explaining 22% of the variance in falls, and correctly classifying 73.7% of cases as fallers or non-fallers. Reduced SF-36v2 general health sub-scale, increased planned physical activity and previous falls in the preceding year were predictors of falls. Those reporting ≥1 fall pre-operatively were three times more likely to fall post-operatively.

CONCLUSION

People awaiting hip or knee joint replacement surgery might present with complex conditions that predispose them to greater risk of falling post-operation. Review of general health and history of falling is recommended pre-operatively to identify patients at risk.

Residual effects of eszopiclone and placebo in healthy elderly subjects: a randomized double-blind study

Next-day residual effects are a common problem with current hypnotics. The purpose of the present study was to evaluate the residual effects of eszopiclone on the physical and cognitive functions of healthy elderly people in the early morning and the day following drug administration. Four men and six women aged 63–72 years were administered eszopiclone 1 mg or placebo in a randomized, double-blind and crossover design. Measures of objective parameters and subjective ratings were obtained at 4:00, 6:00, and every 2 h from 6:00 to 16:00 hours. For the timed up-and-go test, the main effects of time were seen. For the critical flicker fusion, eszopiclone had significantly worse results compared to placebo in early morning (4:00). There were no significant differences between eszopiclone and placebo in other objective assessments. For the sleep latency, eszopiclone had significantly shorter results compared to placebo (eszopiclone vs placebo = 28.4 vs 52.5 min, p = 0.047). Feeling of deep sleep and the number of wake after sleep onset did not show any significant differences between eszopiclone and placebo. Based on the above results, the changes of physical and cognitive functions in the healthy elderly after taking hypnotics, it was found that eszopiclone 1 mg is likely to be unharmful for the healthy elderly. Further studies of elderly insomniacs with midnight awakenings are needed.
