Prevalence, country-specific prescribing patterns and determinants of benzodiazepine use in community-residing older adults in 7 European countries. BMC Geriatr 2024; 24:240. [PMID: 38454372 PMCID: PMC10921596 DOI: 10.1186/s12877-024-04742-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2023] [Accepted: 01/24/2024] [Indexed: 03/09/2024] Open
Abstract
BACKGROUND The use of benzodiazepines (BZDs) in older population is often accompanied by drug-related complications. Inappropriate BZD use significantly alters older adults' clinical and functional status. This study compares the prevalence, prescribing patterns and factors associated with BZD use in community-dwelling older patients in 7 European countries. METHODS International, cross-sectional study was conducted in community-dwelling older adults (65 +) in the Czech Republic, Serbia, Estonia, Bulgaria, Croatia, Turkey, and Spain between Feb2019 and Mar2020. Structured and standardized questionnaire based on interRAI assessment scales was applied. Logistic regression was used to evaluate factors associated with BZD use. RESULTS Out of 2,865 older patients (mean age 73.2 years ± 6.8, 61.2% women) 14.9% were BZD users. The highest prevalence of BZD use was identified in Croatia (35.5%), Spain (33.5%) and Serbia (31.3%). The most frequently prescribed BZDs were diazepam (27.9% of 426 BZD users), alprazolam (23.7%), bromazepam (22.8%) and lorazepam (16.7%). Independent factors associated with BZD use were female gender (OR 1.58, 95%CI 1.19-2.10), hyperpolypharmacy (OR 1.97, 95%CI 1.22-3.16), anxiety (OR 4.26, 95%CI 2.86-6.38), sleeping problems (OR 4.47, 95%CI 3.38-5.92), depression (OR 1.95, 95%CI 1.29-2.95), repetitive anxious complaints (OR 1.77, 95%CI 1.29-2.42), problems with syncope (OR 1.78, 95%CI 1.03-3.06), and loss of appetite (OR 0.60, 95%CI 0.38-0.94). In comparison to Croatia, residing in other countries was associated with lower odds of BZD use (ORs varied from 0.49 (95%CI 0.32-0.75) in Spain to 0.01 (95%CI 0.00-0.03) in Turkey), excluding Serbia (OR 1.11, 95%CI 0.79-1.56). CONCLUSIONS Despite well-known negative effects, BZDs are still frequently prescribed in older outpatient population in European countries. Principles of safer geriatric prescribing and effective deprescribing strategies should be individually applied in older BZD users.

Abstract
RESUMO: Objetivo: Investigar a prevalência e os fatores associados ao uso de psicofármacos entre idosos. Métodos: O estudo, realizado em 2003, baseou-se no Inquérito de Saúde da Região Metropolitana de Belo Horizonte (RMBH). Participaram do estudo 1.635 idosos (60 anos ou mais) residentes nos municípios da RMBH, selecionados por meio de amostra probabilística complexa. Modelos de regressão logística foram utilizados para identificar os fatores associados ao uso de psicofármacos, considerando o nível de significância de 5,0%. Resultados: A prevalência de uso de psicofármacos foi de 13,4%, sendo 8,3% para uso de benzodiazepínicos e 5,0% para antidepressivos. Os fatores independentemente associados ao uso de psicofármacos foram sexo feminino (OR = 2,20; IC95% 1,49 - 3,27), relato de diagnóstico médico para depressão (OR = 6,42; IC95% 4,31 - 9,55), ter realizado 5 ou mais consultas médicas nos últimos 12 meses (OR = 2,15; IC95% 1,32 - 3,53) e afiliação a plano de privado saúde (OR = 2,69; IC95% 1,86 - 3,88). Conclusão: A prevalência observada foi semelhante ao verificado entre idosos brasileiros e o padrão de associações detectado foi consistente com o observado em populações idosas de países de maior renda, sendo o relato de diagnóstico médico para depressão o fator mais fortemente associado ao uso de psicofármacos.

Abstract
Aim To investigate whether the use of long-acting benzodiazepines, in individuals aged 65 and over is mediated by physical or psychological factors. BACKGROUND Long-acting benzodiazepine consumption among older people has implications for mortality, morbidity and cost-effective prescribing. Two models explain benzodiazepine use in this age group, one linked to physical illness and disability and one to psychological factors. METHODS Secondary analysis of baseline data from a study of 1059 community-dwelling non-disabled people aged 65 years and over recruited from three general practices in London. For this analysis, use of long-acting benzodiazepines was defined as any self-reported use of diazepam or nitrazepam in the last four weeks. Associations between demographic factors, health service use, and physical and psychological characteristics and benzodiazepine use were investigated. Findings The prevalence of benzodiazepine use in this sample was 3.3% (35/1059). In univariate analyses, benzodiazepine use was associated with female gender, low income, high consultation rates, physical factors (medication for arthritis or joint pain, polypharmacy, difficulties in instrumental activities of daily living, recent pain) and psychological factors (poor self-perceived health, social isolation, and symptoms of anxiety or agitation). In a multivariate logistic regression analysis only two factors retained statistically significant independent associations with benzodiazepine use: receiving only the state pension (OR=4.0, 95% CI: 1.70, 9.80) and pain in the past four weeks (OR=3.79, 95% CI: 1.36, 10.54).

Abstract
This study aimed to determine if self-reported social support and life events explained differences in levels of anxiety and depression among 109 elderly psychotropic drug users compared to 90 nonusers (aged 62 to 98). Two thirds of the respondents were French-speaking, mostly female (82.1%) and widowed (57.4%), and recipients of a home care program in Montreal, Canada. The life event and social support scales, broken down by item value, did not differentiate users from nonusers, except for feelings of loneliness reported by 40% of users compared to only 16% of nonusers (p < .001). Analysis of the relation between psychiatric symptomatology and psychosocial variables, broken down by item value, showed greater sensitivity among users to perceived (subjective) lack in social support. In contrast, only “feelings of loneliness” had an effect on the level of mental health of nonusers. There was no effect with regard to objective items of social support.

Abstract
Neuroleptics, also called antipsychotic drugs (e.g., haloperidol, risperidone) are the cornerstone drug therapy for psychiatric disorders. Despite the fact that they are widely used in nursing homes, little is known about their clinical determinants. The goal of this cross-sectional study was to determine the prevalence rate of neuroleptic administration and to identify their determinants among 2,332 elderly residents in nursing homes. Among the residents, 649 (27.8%) had taken at least one neuroleptic drug. According to the logistic regression, the factors associated with neuroleptic drug consumption were younger age, few hours of family visits, severe cognitive impairment, insomnia, physical restraint, and disruptive behavior. In conclusion, neuroleptic drugs are administered to more than a quarter of residents in nursing homes. Alternative solutions to sleep problems and disruptive behaviors of the elderly living in long-term-care facilities should be implemented in order to reduce unnecessary use of neuroleptics.

Social differences associated with the use of psychotropic drugs among men and women aged 65 to 74 years living in the community: the International Mobility in Aging Study (IMIAS). BMC Geriatr 2015; 15:85.

Abstract
Background Elderly persons make greater use of psychotropic drugs, but there are few international studies on social differences in the use of these medications. The aim of this study is to examine social differences in the use of psychotropic drugs among persons aged 65–74 years in the International Mobility in Aging Study (IMIAS). Methods The sample consisted of 1,995 participants in the IMIAS 2012 baseline study in Saint-Hyacinthe (Canada), Kingston (Canada), Tirana (Albania), Manizales (Colombia), and Natal (Brazil). During home visits, all medication taken by the participants in the previous 15 days was recorded. We then used the Anatomical Therapeutic Chemical classification system to code psychotropic drugs as anxiolytics, sedatives, hypnotics (ASH); antidepressants (ADP); or analgesics, antiepileptics, or antiparkinsonians (AEP). Prevalence ratios for psychotropic drug use according to sex, education, income, and occupation were estimated by fitting a Poisson regression and controlling for demographic and health covariates. Results Psychotropic drug use was higher among Canadian participants than among those living outside Canada. Prevalence of AEP drug use was higher for women than men in the Canadian and Latin American sites. In Tirana, antidepressant drugs were rarely used. Socioeconomic differences varied among sites. In the Canadian cities, low socioeconomic standing was associated with higher frequency of psychotropic drug use. In the Latin American cities, elderly people with high education and income levels showed a higher level of antidepressant drug use, while people with manual occupations had a higher use of AEP drugs. In Tirana, ASH drug use was higher among those with low income. Conclusion An inverse association was observed between socioeconomic standing and psychotropic drug use in Canada, while the opposite was true in Latin America. Albania was notable for an absence of antidepressant use and greater use of ASH drugs among low-income groups.

Abstract
Objective Estimate the prevalence of psychotropic drugs use in the city of Rio de Janeiro, Brazil, and establish its relationship with the presence of mental disorders. Methods A probabilistic sample of non-institutionalized individuals, from the general population of Rio de Janeiro (n = 1208;turn out:81%), 15 years or older, who were interviewed using the Composite International Diagnostic Interview 2.1 (depression, anxiety-phobia, OCD\PTSD, alcoholism sections), and asked about their psychotropic use during a 12 and one-month period before the interview. Data were collected between June/2007-February/2008.The prevalence was estimated with a confidence interval of 95%. The associations between psychotropics use and mental disorders were analyzed through a logistic regression model (Odds Ration – OR). Results The one-month prevalence of psychotropic drug use was 6.55%, 3.19% for men and 9.13% for women. Antidepressants were the most frequently used drug (2.78%), followed by anorectics (1.65%), tranquilizers (1.61%) and mood stabilizers (1.23%). General practitioners issued the highest number of prescriptions (46.3%), followed by psychiatrists (29.3%); 86.6% of the psychotropic drugs used were paid for by the patient himself. Individuals with increased likelihood of using psychotropic drugs were those that had received a psychiatric diagnosis during a one-month period before the study (OR:3.93), females (OR:1.82), separated/divorced (OR:2.23), of increased age (OR:1.03), with higher income (OR:2.96), and family history of mental disorder (OR:2.59); only 16% of the individuals with a current DSM IV diagnosis were using a psychotropic drug; 17% among individuals with a depression-related diagnosis and 8% with Phobic Anxiety Disorders-related diagnosis used psychotropics. Conclusion Approximately 84% of individuals displaying some mental disorder did not use psychotropic drugs, which indicates an important gap between demand and access to treatment. A significant failure is evident in the health system for patients with mental disorders; this could be due to health workers' inability to recognize mental disorders among individuals.

Abstract
ESA study data were paired with Quebec medical and pharmaceutical services records to document potentially inappropriate benzodiazepines (Bzs) prescriptions among community-dwelling adults aged 65 and older. Results indicate that 32 per cent of respondents took a mean daily dose of 6.1 mg of equivalent diazepam for, on average, 205 days per year. Almost half (48%) of Bzs users received a potentially inappropriate benzodiazepine prescription at least once during the year preceding the survey. About 23 per cent received at least one concomitant prescription of a Bz and another drug that could result in serious interaction. In addition, individuals aged 75 and older were more likely to receive Bzs for a longer period of time than those aged 65-74. Number of pharmacies used was associated with inappropriate Bzs prescriptions. Our results argue in favour of a more integrated health services system, including a regular review of older adults' drug regimens.

Abstract
OBJECTIVE The prevalence of benzodiazepine use among community-dwelling older persons varies between 10% and 30%. The aim of this study was to explore the association between leisure activities and the use of benzodiazepine among older persons living at home. METHODS The study population included 4848 persons aged 65 years and over living in either of two French cities. Information was collected from a questionnaire administered to the respondents by trained psychologists during face-to-face interviews at home and from a self-administered questionnaire. Baseline examination included socio-demographic characteristics, drug use and leisure activities. We classified as benzodiazepine users subjects who reported use of at least one benzodiazepine during the month preceding the interview. The association between the use of benzodiazepine and leisure activities was assessed by logistic regression adjusted on known potential confounders. RESULTS More than 18% of participants reported use of at least one benzodiazepine. The adjusted odds ratio (OR) of benzodiazepine use associated with no or lower participation versus participation in the following activities were as follows: OR = 1.31 (95% confidence interval (CI): 1.09 to 1.58) for mental activity; OR = 1.50 (CI: 1.12 to 2.03) for physical activity; OR = 1.28 (CI: 1.05 to 1.55) for productive activity and OR = 0.82 (CI: 0.69 to 0.97) for recreational activity. CONCLUSION Low engagement in stimulating activities and high engagement in sedentary activities were associated with recent benzodiazepine use.

Abstract
BACKGROUND Drugs with sedative properties are among the most widely used drugs in community-dwelling older people. Use of sedative drugs has been associated with falls and fractures, cognitive and memory impairment and impaired physical function among older people. The sedative load model has been developed to quantify the cumulative effect of taking multiple drugs with sedative properties. OBJECTIVE The objective of the study was to investigate factors associated with sedative load among community-dwelling older people, using data collected as part of the Finnish Geriatric Multidisciplinary Strategy for the Good Care of the Elderly (GeMS) study. METHODS The GeMS study was a randomized, comparative study that evaluated a model for geriatric assessment, care and rehabilitation using a study sample of 1000 persons aged≥75 years who were living in Kuopio, Finland. Of these, 700 people consented to participate and were community-dwelling. Demographic, diagnostic and drug use data (both regular and when-required drugs) were elicited during nurse interviews. For the current analysis, sedative load was computed using a previously published model, in which drugs taken on a regular and when-required basis were classified into one of four groups according to their sedative potential. Group 1 included primary sedatives (sedative rating 2) and group 2 included drugs with sedation as a prominent side effect (sedative rating 1). Each participant's sedative load was calculated by summing the sedative ratings of group 1 and 2 drugs. Logistic regression models were used to investigate factors associated with sedative load. RESULTS Twenty-nine percent of participants (n=205) had a sedative load of ≥1 (i.e. used one or more drugs with sedative properties), and 22% (n=158) had a sedative load of ≥2 (i.e. used either one primary sedative or two drugs with sedation as a prominent adverse effect or preparations with a sedating component) when considering regularly used drugs. A sedative load of ≥2 that related to regularly used drugs was associated with female sex (odds ratio [OR] 1.65; 95% CI 1.02, 2.67), poor self-perceived health (OR 2.06; 95% CI 1.25, 3.38), impaired instrumental activities of daily living [IADL] (OR 1.89; 95% CI 1.18, 3.01) and often feeling lonely (OR 4.72; 95% CI 2.15, 10.40). The same factors remained significantly associated with a sedative load of ≥2 after drugs used on a when-required basis were included in the analyses. CONCLUSIONS The advantages of the sedative load model were that it included drugs with sedative properties prescribed for somatic diseases, described cumulative exposure to drugs that exert sedative effects through multiple mechanisms in the CNS, and incorporated a sedative rating for each drug. In an older population, female sex, impaired IADL, poor self-perceived health, and loneliness were associated with higher sedative load. Clinicians should remain cognizant of these factors when reviewing drug regimens and targeting interventions to optimize sedative use.

Abstract
OBJECTIVES To assess: (1) changes in use of psychotropic medications across two cohorts, 10 years apart, of community-dwelling elderly and the socio-demographic, physical and mental health correlates of their use; and (2) changes in psychotropic medication use over 3.5 years follow-up. METHODS Data were taken from two national surveys of the Israeli Jewish population aged 75–94, which, respectively, sampled two cohorts in 1989 (n=1200) and again in 1999 (n=421). Psychotropic medications were assessed from the list of all medications recorded during a face-to-face interview. The current analysis focused on two medication groups: anxiolytics and sedatives/hypnotics and antidepressants. RESULTS Sedatives/hypnotics and anxiolytics use increased from 22.2% in 1989 to 25.4% in 1999 and antidepressants from 3.8% to 4.8% (both nonsignificantly) corresponding to a decline in the health profile of community-dwelling older adults. Similar patterns of associations were observed for socio-demographics, physical, and mental health status indicators with the use of psychotropic medications across the two cohorts. The pooled multivariate analysis showed significantly higher use of sedative/hypnotics and anxiolytics among women and lower use among religious elderly. Additional risk factors were sleeping problems, number of other medications, depressive symptoms, and traumatic life events. Antidepressants use was related to a higher education, ADL disability, and depressive symptoms. Longitudinally, use of psychotropic medications was not significantly different among participants who were followed again after 3.5 years. CONCLUSIONS Sedative/hypnotics and anxiolytics use was relatively high while antidepressants use was low even among depressed elderly suggesting that some depressed elderly were treated inappropriately with benzodiazepines.

Abstract
BACKGROUND Longitudinal research on determinants of initiated and continued benzodiazepine (BZD) use is inconsistent and has identified many possible determinants. It is unclear which of those are most important in the prediction of BZD use. We aimed to identify the most important predictors of initiated and continued BZD use. Therefore, we analyzed the most consistently identified determinants from previous research plus some new determinants. METHODS We identified baseline and 2-year longitudinal predictors of initiated BZD use (vs nonuse) among 2205 baseline BZD nonusers and of continued use (vs discontinued use) among 369 baseline BZD users in the Netherlands Study of Depression and Anxiety using logistic regression analyses. RESULTS During follow-up, BZD use was initiated by 4.9% of BZD nonusers at baseline. Initiated use was predicted by insomnia (odds ratio [OR], 1.60), enduring anxiety symptoms (OR, 2.02), entering secondary care during follow-up (OR, 2.85), and past BZD use (OR, 3.57). Positive life events during follow-up reduced the likelihood of BZD initiation (OR, 0.76). Of BZD users at baseline, 54.2% continued use during the entire follow-up period. Continuation of BZD use was predicted by higher age (OR, 1.03), severe anxiety (OR, 1.85), and a long duration of BZD use (OR, 1.54). Leaving secondary care was associated with less continued BZD use (OR, 0.29). CONCLUSION Insomnia and anxiety were the main risk factors of initiated use, whereas advanced age and anxiety severity were the main risk factors of continued use. Sex, education, pain, and physical health seemed to be less important.

Abstract
INTRODUCTION Many studies have reported excessive consumption of psychotropic drugs in the elderly but none have related psychotropic drug use to psychiatric symptoms and sleep disorders in community-dwelling patients aged more than 65 years old in Spain. MATERIAL AND METHODS We performed a cross sectional study in a representative sample (9,739 persons) from the population aged more than 55 years old in the city of Zaragoza in 2001. A total of 3,714 persons aged more than 65 years old were interviewed. The data belonged to the ZARADEMP project. RESULTS The mean age of the sample was 76.9 years (59.2% women and 40.8% men). Anxiolytics or antidepressants were consumed by 22.6% of the sample. A diagnosis of depression was made in 12.9%, anxiety in 1.6% and insomnia in 36%. We found high consumption of anxiolytics, especially in persons with depression (42.2%) and low consumption of antidepressants, especially in persons with a diagnosis of depression (15.4%) and in those with depressive symptoms (8.2%). CONCLUSIONS A correct psychiatric diagnosis is essential before psychotropic drugs are used to ensure appropriate treatment of the elderly with psychiatric symptoms.

Abstract
OBJECTIVE To measure the prevalence of benzodiazepine (BZD) use and to explore associated demographic and clinical variables of BZD use within a cohort of 75-year- old inhabitants of an urban district of Vienna. METHODS This is a prospective, interdisciplinary cohort study on aging. Our investigation is based on the first consecutive 500 subjects that completed the study protocol. Demographic and clinical characteristics, benzodiazepine and antidepressant use were documented using a standardized questionnaire. Affective status was assessed using the Hamilton Depression Rating Scale (HAMD), the Geriatric Depression Scale (GDS), and the Spielberger State-and Trait Anxiety Inventory subscales (STAI). RESULTS Prevalence of BZD use was 13.8%. Compared to non-users, BZD users had significantly higher mean scores at the HAMD (p = 0.001), the GDS (p = 0.026), and the Spielberger State-and Trait Anxiety Inventory subscales (p = 0.003; p = 0.001). Depression was found in 12.0% (HAMD) and 17.8% when using a self-rating instrument (GDS). Less than one-third of depressed subjects were receiving antidepressants. Statistically equal numbers were using benzodiazepines. CONCLUSIONS Inappropriate prescription of BZD is frequent in old age, probably indicating untreated depression in many cases. The implications of maltreated geriatric depression and the risks associated with benzodiazepine use highlight the medical and socioeconomic consequences of inappropriate BZD prescription.

Abstract
Background Benzodiazepines are frequently prescribed to elderly patients' despite concerns about adverse effects leading to injurious falls. Previous studies have not investigated the extent to which patients with pre-existing risk factors for falls are prescribed benzodiazepines. The objective of this study is to assess if some of the risk factors for falls are associated with new benzodiazepine prescriptions in elderly persons. Methods Using provincial administrative databases, elderly Quebec residents were screened in 1989 for benzodiazepine use and non-users were followed for up to 5 years. Logistic regression models were used to evaluate potential predictors of new benzodiazepine use among patient baseline characteristics. Results In the 252,811 elderly patients who had no benzodiazepine prescription during the baseline year (1989), 174,444 (69%) never filled a benzodiazepine prescription and 78,367 (31%) filled at least one benzodiazepine prescription. In the adjusted analysis, several risk factors for falls were associated with statistically significant increases in the risk of receiving a new benzodiazepine prescription including the number of prescribing physicians seen at baseline (OR: 1.12; 95% CI 1.11–1.13), being female (OR: 1.20; 95% CI 1.18–1.22) or a diagnosis of arthritis (OR: 1.11; 95% CI 1.09–1.14), depression (OR: 1.42; 95% CI 1.35–1.49) or alcohol abuse (OR: 1.24; 95% CI 1.05–1.46). The strongest predictor for starting a benzodiazepine was the use of other medications, particularly anti-depressants (OR: 1.85; 95% CI 1.75–1.95). Conclusion Patients with pre-existing conditions that increase the risk of injurious falls are significantly more likely to receive a new prescription for a benzodiazepine. The strength of the association between previous medication use and new benzodiazepine prescriptions highlights an important medication safety issue.

Abstract
Benzodiazepines and other omega-receptor agonists are frequently used for sleep and anxiety disorders. We studied the rates, correlates, and safety of individual benzodiazepines and zolpidem use from the records of 3690 patients in a national cohort of Dialysis Morbidity and Mortality Study Wave 2 data. We assessed drug utilization and an association between drug use and all-cause mortality. Overall, 14% of incident dialysis patients used a benzodiazepine or zolpidem. Women, Caucasians, current smokers, and patients with chronic obstructive pulmonary disease were more likely to use these drugs, whereas patients with cerebrovascular disease were less likely to use these drugs. In adjusted analyses, benzodiazepine or zolpidem use was associated with a 15% higher mortality rate. Chronic obstructive pulmonary disease significantly modified this association, suggesting that these patients were at higher risk. No association was found between benzodiazepine use and greater risk for hip fracture. We conclude that benzodiazepine or zolpidem use is common in incident dialysis patients and may be associated with greater mortality. Further studies are needed to elucidate the safety of these drugs in the dialysis population, which may lead to cautious and restrictive utilization of omega-receptor agonists in dialysis patients.

Abstract
PURPOSE This study mainly aimed at describing the prevalence of psychotropic medication consumption in the Spanish elderly population between the years 1993 and 2003. METHODS Descriptive, cross-sectional study covering the Spanish population aged 65 years and over, using data drawn from the 1993 and 2003 Spanish National Health Surveys (ENSS). A total of 9570 interviews were analysed (3436 from 1993 and 6134 from 2003). The independent variables were sociodemographic and health-related, and the dependent variable was total consumption of psychotropic medication. Using logistic multivariate regression models, we have analysed the temporal evolution of psychotropic medication consumption between 1993 and 2003. RESULTS The prevalence of consumption was significantly higher in women (6.7% from 1993 and 26.4 % from 2003) versus men (2.4% from 1993 and 10.6% from 2003) (p < 0.001). Multivariate analysis, highlighted the association between increased psychoactive drug intake and sex, nervous, depressive, sleep disorders and negative perception of health, displayed a strong association with consumption of psychoactive drugs across the 2 years. CONCLUSIONS In Spain, the prevalence of psychoactive drug consumption is higher among elderly women than men, and increases with negative perception of health. The prevalence of consumption was significantly higher in the year 2003.

Abstract
CONTEXT AND OBJECTIVE Although psychotropics are one of the classes of medications most prescribed in nursing homes for the elderly, studies examining prescribing patterns are limited in both number and scope. The present study was undertaken to investigate factors associated with general psychotropic use in a nursing home in Brazil. DESIGN AND SETTING Retrospective observational study at the Nursing Home for the Elderly, Institute of Biosciences, Universidade Estadual Paulista. METHODS Information on prescriptions was retrieved from the medical records of 108 elderly residents in a nursing home. Sixty-five of these patients, with mean age 74.5 years (+/-standard deviation 9.4 years), who were taking medications on a regular basis, comprised the sample. The effects of demographic and clinical variables on the psychotropic prescription pattern were examined. RESULTS Females were more likely to receive psychotropics (p = 0.038). Individuals on medicines for cardiovascular diseases received psychotropics less frequently (p = 0.001). The number of prescribed psychotropics correlated negatively with both age (p = 0.009) and number of non-psychotropic drugs (p = 0.009). CONCLUSIONS Although preliminary, the present results indicated that cardiovascular disease was the clinical variable that most influenced psychotropic prescription. Physicians' overconcern regarding drug interactions might at least partially explain this result. Further investigations involving larger sample sizes from different regions are warranted to confirm these findings.

Abstract
OBJECTIVES To determine whether benzodiazepine use is associated with incident disability in mobility and activities of daily living (ADLs) in older individuals. DESIGN A prospective cohort study. SETTING Four sites of the Established Populations for Epidemiologic Studies of the Elderly. PARTICIPANTS This study included 9,093 subjects (aged > or =65) who were not disabled in mobility or ADLs at baseline. MEASUREMENTS Mobility disability was defined as inability to walk half a mile or climb one flight of stairs. ADL disability was defined as inability to perform one or more basic ADLs (bathing, eating, dressing, transferring from a bed to a chair, using the toilet, or walking across a small room). Trained interviewers assessed outcomes annually. RESULTS At baseline, 5.5% of subjects reported benzodiazepine use. In multivariable models, benzodiazepine users were 1.23 times as likely as nonusers (95% confidence interval (CI) = 1.09-1.39) to develop mobility disability and 1.28 times as likely (95% CI = 1.09-1.52) to develop ADL disability. Risk for incident mobility was increased with short- (hazard ratio (HR) = 1.27, 95% CI = 1.08-1.50) and long-acting benzodiazepines (HR = 1.20, 95% CI = 1.03-1.39) and no use. Risk for ADL disability was greater with short- (HR = 1.58, 95% CI = 1.25-2.01) but not long-acting (HR = 1.11, 95% CI = 0.89-1.39) agents than for no use. CONCLUSION Older adults taking benzodiazepines have a greater risk for incident mobility and ADL disability. Use of short-acting agents does not appear to confer any safety benefits over long-acting agents.

Abstract
Benzodiazepine (BZD) drug use among community-dwelling seniors is a significant health issue. Although long-term use of BZDs by seniors is a recognized problem, little is known about the mental health of the consumers. Better knowledge of their mental health would help nurses in identifying the psychological needs of this population. The goals of this longitudinal study1 (n = 138) were to describe the mental health status of long-term users of BZDs and to compare it with the mental health of seniors who have either begun or stopped consuming BZDs over a 1-year period (from Phase 1 to Phase 2). Results showed that one third of long-term users of BZDs do not present any mental health problem. Furthermore, no differences were observed between the mental health statuses of new users of BZDs, individuals who stopped using BZDs, and long-term users of BZDs. In conclusion, at least one third of long-term users of BZDs should stop using these drugs, and nurses should play a leading role in helping these seniors withdraw from BZD consumption.

Abstract
OBJECTIVE The aim of this study was to estimate the incidence of benzodiazepine use in an elderly population and to identify associated factors. METHODS Data were collected in four self-report questionnaires on the use of sedatives and sleeping drugs. These questionnaires were sent every 6 months, over a 2-year period, to the 1272 elderly subjects interviewed at the first follow-up examination of the EVA (Epidemiology of Vascular Aging) Study. RESULTS The incidence rate of benzodiazepine use was 4.7 per 1000 person-months (95% confidence interval [CI] 3.6, 5.8). In multivariable analyses (logistic regression model), incident use of benzodiazepines was significantly associated with depressive or anxious symptoms (odds ratio [OR] = 3.3; 95% CI 1.7, 6.4), high use of non-psychotropic drugs (> or = 3; OR = 1.8; 95% CI 1.1, 3.1) and female gender (OR = 1.9; 95% CI 1.1, 3.3). CONCLUSION Simultaneous use of benzodiazepines and other medications should be carefully assessed in elderly patients, considering the risk of adverse drug reactions and drug-drug interactions.

Abstract
Résumé
La consommation non appropriée d’anxiolytiques, de sédatifs et d’hypnotiques (ASH) chez les personnes âgées est un problème de santé publique important. Près de 35 % de la population âgée vivant à domicile consomment ces médicaments, en moyenne 206 jours par an. Selon les données québécoises, les personnes âgées de plus de 65 ans consomment cinq fois plus d’ASH que les individus âgés entre 18 et 64 ans. L’utilisation des ASH ne serait pas uniquement déterminée par la présence de symptômes, mais aussi par les caractéristiques psychosociales des sujets. En outre, plusieurs chercheurs ont suggéré que l’entourage et le système de soins étaient des facteurs environnementaux pouvant faciliter ou inhiber la consommation de ces médicaments chez les personnes âgées. Un cadre conceptuel est proposé pour aider à spécifier adéquatement les diverses hypothèses explicatives de ce comportement social de santé et, par conséquent, pour aider à mieux cibler les interventions visant à le modifier.

Abstract
BACKGROUND: In the many descriptive studies on prescribed psychotropic drug use by community-dwelling older persons, several sociodemographic and other factors associated with drug use receive inconsistent support. METHOD: Empirical reports with data on at least benzodiazepine or antidepressant drug use in samples of older persons published between 1990 and 2001 (n = 32) were identified from major databases and analyzed to determine which factors are most frequently associated with psychotropic drug use in multivariate analyses. Methodological aspects were also examined. RESULTS: Most reports used probability samples of users and non-users and employed cross-sectional designs. Among variables considered in 5 or more reports, race, proximity to health centers, medical consultations, sleep complaints, and health perception were virtually always associated to drug use. Gender, mental health, and physical health status were associated in about two-thirds of reports. Associations with age, marital status, medication coverage, socioeconomic status, and social support were usually not observed. CONCLUSIONS: The large variety of methods to operationalize drug use, mental health status, and social support probably affected the magnitude of observed relationships. Employing longitudinal designs and distinguishing short-term from long-term use, focusing on samples of drug users exclusively, defining drug use and drug classes more uniformly, and utilizing measures of psychological well-being rather than only of distress, might clarify the nature of observed associations and the direction of causality. Few studies tested specific hypotheses. Most studies focused on individual characteristics of respondents, neglecting the potential contribution of health care professionals to the phenomenon of psychotropic drug use among seniors.

Abstract
OBJECTIVE We estimated prescription psychotropic medication use among US adults. METHODS We examined household interview data from the third National Health and Nutrition Examination Survey (1988-1994) for persons 17 years and older (n=20,050). STUDY DESIGN AND SETTING An estimated 10 million adults (5.5%) reported psychotropic medication use during a 1-month period. The use of anxiolytics, sedatives, and hypnotics (ASH) was most common (3.2%), followed by antidepressants (2.3%), antipsychotics (0.7%), and antimanics (0.1%). Psychotropic medication use was more prevalent among women than men (P<.001), non-Hispanic whites than non-Hispanic blacks (P<.001) and Mexican Americans (P<.001), and older rather than younger age groups (P<.001). Psychotropic medication use was also most common among those below the federal poverty level, those with no high school education, and among insured persons. Only 1% of adults used two or more psychotropic medications monthly. CONCLUSION Many adults use psychotropic medications on a monthly basis. ASH users comprised the largest proportion of psychotropic medication users. Patterns of use varied by several socio-demographic factors.

Abstract
Gender differences in depressive symptoms, in the diagnosis of major/minor depression, and in the use of antidepressant medication were investigated. The sample included 249 pairs of unlike-sex twins, who were between 70 and 80 years of age at the initial, baseline assessment. A follow-up, in which both members of 145 twin pairs participated, was carried out four years later. Participants completed the Centre for the Epidemiologic Studies Depression Scale (CES-D) for depressive symptoms. Current use of antidepressant medicine was assessed. Medical records of major/minor depression from the period 1985-1998, including a summary of those diagnoses in earlier years, were gathered from several sources. Women had a higher frequency of depressive symptoms and depression diagnoses than their twin brothers. Depressive symptoms and diagnosis of depression increased over time, slightly more among men. The gender difference and increase over time in the depressive symptoms were related to differences in socio-economic status and physical functioning in men and women. No gender difference was found in the use of antidepressant medication.

Abstract
BACKGROUND There have been few general population studies of the effects of psychotropic treatment on cognitive functioning in the elderly. Current evidence based on studies with numerous procedural shortenings supports the notion of the detrimental effect. OBJECTIVES To examine changes in a wide range of specific cognitive abilities across time in a general population sample in order to establish a relationship between psychotropic drug use and cognitive performance, and to estimate to what extent such cognitive changes may be attributable to psychotropic use or other factors, notably age and co-morbidity. METHOD We analysed the data from the Eugeria longitudinal study of cerebral ageing. Three hundred and seventy two subjects (263 female and 109 male) were visited at their place of residence and given a computerized cognitive examination. Depressive symptomatology and depressive episodes were defined according to ICD-9 criterias and medication use were established. Four categories of psychotropic consumers was differentiated. Using a logistic regression model, comparisons were made between consumers and non-consumers. RESULTS A significant positive effect in chronic consumers was found on tests of secondary memory (delayed verbal recall: Odds Ratio (OR)=1.22; 95% Confidence Intervals (CI) [1.04-1.43]; p=0.013) and this effect is principally attributable to antidepressants with significant effects being shown for both verbal (OR=1.59; 95%CI [1.18-2.14]; p=0.002) and visual recall (OR=1.51; 95%CI [1.05-2.16]; p=0.025). No effect is found for benzodiazepines. CONCLUSIONS Contrary to the common belief that psychotropic drug use has a detrimental effect on cognitive function of elderly people, even long term use is seen to be benign. We attest to the positive effects of antidepressant therapy on secondary memory.

Abstract
OBJECTIVES To examine psychotropic prescription use in community-dwelling elderly in the United States and its association with predisposing, enabling, and need factors. DESIGN Retrospective analysis of the 1996 Medical Expenditure Survey (MEPS). SETTING A national representative sample survey of the United States non-institutionalized population. PARTICIPANTS Community-dwelling persons aged 65 and older participating in the MEPS. MEASUREMENTS Psychotropic prescription use patterns and factors associated with the use of psychotropics in general as well as of individual classes, specifically antidepressants, antianxiety agents, and sedative/hypnotics. RESULTS According to the MEPS, more than 6 million (19%) community-dwelling elderly persons used psychotropic medications in 1996. Nearly 3 million (9.1%) elderly were taking antidepressants, almost 2.5 million (7.5%) antianxiety agents, and 1.5 million (4.8%) sedative/hypnotics. Several correlates of psychotropic prescription use were identified. Enabling (e.g., prescription insurance) and need (e.g., health status) factors were found to be consistently associated with the use of antidepressant, antianxiety, and sedative/hypnotic agents. Predisposing factors such as sex, race, region, and education varied with the type of psychotropic drug class examined. CONCLUSION Nearly one in five community-dwelling elderly persons used psychotropic medications, primarily antidepressants followed by antianxiety agents. Enabling and need factors were consistently associated with psychotropic classes examined, whereas most predisposing factors varied with the type of psychotropic drug class.

Abstract
UNLABELLED The terms regular, excessive or intermittent consumption do not characterize type of consumption, the profile of the drug user, or the threshold of drug dependence. OBJECTIVE To characterize trajectories of consumption over a 5-year period and identify sociodemographic and medical characteristics, and modes of consumption associated with the types of trajectories. METHODS 286 drug users from the cohort SUVIMAX agreed to take part in our study. SUVIMAX is a controlled randomized primary prevention trial using nutritional doses of a combination of anti-oxidant vitamins and minerals to reduce cardiovascular diseases and cancers. The data came from the questionnaire that examined each psychotropic drug taken between 1994 and 1998, rates of consumption and the beliefs associated with the drug users' modes of consumption and their dependence profiles. RESULTS A continuous trajectory is defined as uninterrupted consumption during the 5-year follow-up, and an occasional trajectory as an interruption of consumption for at least 1 month. Only 30% of the drug users with a continuous trajectory considered they could do without psychotropic agents. CONCLUSION The consumption of psychotropic drugs is not in itself harmful, but the duration and regularity of drug intake registered over a 5-year period indicate the drug dependence profile. The trajectory is a relevant and operational tool for better adapting therapeutic follow-up.

Abstract
OBJECTIVES To investigate sociodemographic characteristics (SDCs) and health status of older Chinese newly admitted to a nursing home (NH) and to compare them with the characteristics of residents from other racial/ethnic groups. DESIGN Secondary analysis of the admission Minimum Data Set Plus (MDS+). SETTING A New York City municipal NH near Chinatown. PARTICIPANTS Two hundred fifty-eight (125 Chinese, 57 white, 53 Hispanic, and 23 black) of 292 residents consecutively admitted from November 1992 to May 1997 were selected after excluding those younger than 60 or transferred from another NH. MEASUREMENTS SDCs, health status parameters (cognitive performance, physical functioning, mood/behavior patterns, and psychosocial well-being), and morbidity information (most-frequent diagnoses/conditions and medication use) documented in or generated from the MDS+. RESULTS The majority of these Chinese were first-generation immigrants and spoke primarily Cantonese or Mandarin Chinese. Compared with whites, they were more likely to be married, less likely to have lived alone, more likely to be using Medicaid, less likely to make medical decision alone, and more likely to depend on family members for decision-making. Nearly three-quarters of Chinese had cognitive impairment. There was an underdiagnosis of dementia in the Chinese subjects on admission. Severe dependence in activity of daily living was identified in more than one-third of Chinese. Fewer Chinese were using psychotropic medications on admission than the whites. Similar to other groups, many of the Chinese subjects were incontinent of bowel and bladder and had chewing or swallowing problems, hypertension, anemia, and stroke. CONCLUSION This is the first systematic report of the SDCs and health status of a group of newly admitted older Chinese to an urban NH in the United States using the Minimum Data Set database. These findings suggest that Chinese residents are as frail as other racial/ethnic residents on admission. NHs caring for older Chinese need to be sensitive to the presence of dementia, and require a staff that can speak Cantonese and Mandarin Chinese and is comfortable negotiating with families who are more likely to be the designated decision makers.

Abstract
Providing high-quality mental health nursing care should be an important and continuous preoccupation in the gerontological nursing field. As the proportion of elderly people in our society is growing, the emphasis on high-quality care will receive increasing attention from administrators, politicians, organized groups, researchers and clinical nurses. Recent findings illustrate unequivocally the important contribution of nurses to achieving the goal of high-quality geriatric care. However, the quality of care for the elderly with psychological difficulties has not been addressed. The objective of this article is to illustrate that while nurses can accomplish much to improve the well-being and mental health of the elderly, their skills are often underutilized. Psychotropic drugs are often the first-line interventions used by health-care professionals to treat mental health concerns of elderly persons. Alternative therapies that could be implemented and evaluated, such as psychological counselling, supportive counselling, education and life review, are infrequently used. Nevertheless, current scientific data suggest that it would be very advantageous if nurses were to play a dominant role in the care of elderly people who are depressed or experiencing sleep pattern disturbances. The same can be said about elderly chronic users of benzodiazepines, as well as those with cognitive impairment. Evidence for the use of psychotropic medications as a viable treatment option for the elderly both in the community and in the long-term care setting who are experiencing mental health challenges is examined. Alternative non-pharmacological approaches that nurses can use to augment care are also briefly discussed.

Abstract
OBJECTIVES The use of psychotropic drugs has increased continuously over recent years in industrialized countries. In Europe, France has the highest consumption of such drugs. The aim of this study was to identify the sociodemographic and medical factors associated with the use of psychotropic agents. METHODS Data, collected as part of the SUVIMAX (SUpplementation en VItamines et sels Mineraux AntioXydants) prevention trial, from a self- administered questionnaire involving 7299 subjects aged 45-60 years, were subjected to logistic regression analysis. RESULTS A total of 467 subjects used psychotropic drugs (8.4% of the women, 4.6% of the men). Use of psychotropic drugs increased in subjects of both sexes with past history of depression, perception of poor health and use of other drug treatments. Widowhood in men [odds ratio (OR) = 3.4; 95% CI = 1.6-7.3] and divorce in women (OR = 2; 95% CI = 1.2-3.2) were also associated with an increased use of psychotropic drugs. Interaction was demonstrated between educational level and occupational satisfaction in men (OR = 2.9; 95% CI = 1.5-5.8) and between perception of health status and use of other types of medication in women (OR = 6.5; 95% CI = 4.6-9.5). CONCLUSION The results of our study are consistent with those of others in demonstrating that specific socio-occupational factors in men and specific medical factors in women influence extent of use of psychotropic drugs.

Abstract
OBJECTIVES To compare the prevalence of Restless Legs Syndrome (RLS) symptoms in older African-American and Caucasian chronic renal failure patients undergoing maintenance hemodialysis (HD). BACKGROUND Few data are available about the prevalence of RLS in racial groups, although it has been suggested that the African-American population is at lower risk relative to the Caucasian population. Chronic renal failure patients on HD are known to be at increased risk for RLS. METHODS In-person interviews with 308 chronic renal failure patients aged 60-87 living in Georgia being treated by in-center HD. RESULTS More Caucasian patients than African-American patients reported experiencing RLS symptoms during the past 6 months (68 vs. 48%; P=0.0006). In a logistic regression analysis, African-American patients' reduced risk of RLS complaint was independent of patients' age, gender, education, body mass index (BMI), months on dialysis, diabetes as primary diagnosis, presence of cardiovascular comorbidity, and average number of weekly hours of HD. CONCLUSIONS Our data suggested a lower prevalence of RLS among older African-American than among older Caucasian patients on chronic HD. Further study is needed to determine whether this difference also occurs in idiopathic RLS and/or at different ages. The possibility of systematic reporting differences related to race should also be considered.

Abstract
Psychotropic medications are an important treatment approach to mental health disorders; such disorders are common in the elderly population. Elderly patients are more likely to experience adverse effects from these agents than their younger counterparts due to age-related changes in pharmacodynamic and pharmacokinetic parameters. Because of these factors, inappropriate use of psychotropic medications in elderly patients has become a focus of concern. In general an agent is considered inappropriate if the risk associated with its use exceeds its benefit. Implicit and explicit criteria for inappropriate use of medications in the elderly have been created and include psychotropic agents. These criteria vary in their make-up but the explicit criteria tend to agree that amitriptyline, doxepin, and benzodiazepines that have long half-lives are not appropriate. Although explicit inappropriate medication criteria have been in existence since 1991, elderly patients continue to receive inappropriate psychotropic medications. A wide array of factors may be responsible for this practice. Provider-related causes include deficits in knowledge, confusion due to the lack of a consensus on the inappropriate psychotropic criteria, difficulties in addressing an inappropriate medication started by a previous provider, multiple prescribers and pharmacies involved in the care of a patient, negative perceptions regarding aging, and cost issues. Patients may contribute to the problem by demanding an inappropriate medication. Finally, the healthcare setting may inadvertently contribute to inappropriate prescribing by such policies as restrictive formularies or lack of reimbursement for pharmacists' clinical services. Successful approaches to optimising prescribing have been either educational or administrative. Educational approaches (e.g. one-on-one sessions, academic detailing) seek to influence decision making, while administrative approaches attempt to enforce policies to curtail the undesired practice. The US Omnibus Budget Reconciliation Act of 1987, which improved psychotropic medication use in long-term care, is an excellent example of administrative intervention. More research specifically focused on the causes of inappropriate psychotropic medication use and methods to avoid this practice is needed before targeted recommendations can be made.

Abstract
OBJECTIVES Falls among elderly are a well-recognised public health problem. The purpose of the present study was to explore the relation between dementia, number of depressive symptoms, activities of daily living, setting, and risk of falling. METHODS Data for the analysis came from a cross-sectional study about dementia, depression, and disabilities, carried out 1995/96 in Zurich and Geneva. The random sample stratified, by age and gender consisted of 921 subjects aged 65 and more. The interview was conducted by means of the Canberra interview for the Elderly, extended by short questionnaire. The subject was classified as a faller if the subject and/or the informant had reported a fall within the last 12 months prior to the interview. Logistic-regression analysis was used to determine the independent impact of dementia, depressive symptoms, and ADL-score on risk of falling. RESULTS The stepwise logistic regression analysis has revealed a statistically significant association between dementia (OR 2.14, 95% CI 1.15-3.96), two resp. three depressive symptoms (OR 1.64, 95% CI 1.04-2.60) as well as four or more depressive symptoms (OR 2.64, 95% CI 1.39-5.02) and the risk of falling. There was no statistically significant relationship between studied risk factors and the risk of being one-time faller. However, we found a strong positive association between dementia (OR 3.92, 95% CI 1.75-8.79), four or more depressive symptoms (OR 3.90, 95% CI 1.55-9.83) and the risk of being recurrent faller. Moreover, residents of nursing homes (OR 8.50, 95% CI 2.18-33.22) and elderly aged 85 or more (OR 2.29, 95% CI 1.08-4.87) were under statistically significant higher risk of sustaining recurrent falls. CONCLUSIONS The results of the present study confirm that dementia and depression substantially increase the risk of falling.

Abstract
The goal of the study was to compare caregivers who used psychotropic drugs with caregivers who were non-users in order to pinpoint differences in coping styles between the two groups. We performed a secondary analysis of a study on the stress and psychological well-being of persons caring for relatives with dementia. We compared elderly caregivers, as either psychotropic drug users (n = 61) or non-users (n = 133), over various psychosocial characteristics relating to the care-giving context. Results reveal that users, as compared to non-users were: (a) more disturbed (appraised a greater stress) by the relative's dysfunctional behaviours, after controlling for the frequency of the behaviours; and (b) experienced more conflict during interpersonal interactions, although their appraisal of self-satisfaction with formal and informal support to their care-giving activities did not differ significantly. Strikingly, users combined and called on a greater number of problem-focused and emotion-reducing coping strategies than did non-users. They more frequently used affective regulation and information seeking coping styles. Stress-related measures (especially stress appraisal and conflict) contributed more to the variation in mental distress of users than of non-users. Results provide a theoretical and empirical rationale for therapeutic interventions such as the cognitive behavioural approach.

Abstract
This study documents correlates of psychotropic drug use among older adults and compares the results observed in this group to those observed in individuals aged 18-64. A multivariate logistic regression analysis using data from the Quebec Health Survey (1992-1993) was employed to study predisposing and facilitating factors of this behavior. Results showed that 22% of the elderly reported having used anxiolytics, sedatives or hypnotics during the two days preceding the survey, compared to 4.9% of the respondents aged 18-64. Combining both samples, perceived health status, physical functional status, and health services utilization for psychological distress symptoms were the main health factors associated with psychotropic drug use. A significant difference was observed between the two age groups with regard to the association between the respondents' health status and the use of anxiolytics, sedatives or hypnotics. When the effect of other explanatory factors was controlled, older adults in poor health used anxiolytics, sedatives or hypnotics 2.21 times more than individuals aged 18-64 with a similar health condition, whereas older adults in good health used these drugs 7.49 times more than healthy individuals aged 18-64. Furthermore, after controlling for the effect of the respondents' physical and psychological health status, our results showed that more women than men used psychotropic drugs (OR = 1.57; 99% CI = 1.26-1.94). Low-income respondents were also more likely to report using these medications (OR = 1.53; 99% CI = 1.22-1.90). These results were interpreted as supporting the socio-cultural hypothesis of psychotropic drug use, which suggests that the prescribing and utilization of psychotropic drugs is influenced not only by symptoms but also by the social characteristics of individuals. It is suggested that future research may contribute to a better understanding of psychotropic drug utilization in the older adult community-dwelling population by examining consumers' attitudes and health care providers' social values concerning the appropriateness of this behavior.

Abstract
OBJECTIVES Prescriptions of sedatives, hypnotics, and antianxiety medications have decreased over the past 15 years. However, racial differences have not been well investigated in controlled analyses. DESIGN A prospective cohort study. SETTINGS AND PARTICIPANTS The authors analyzed data from a community-based, biracial cohort of older adults (n = 4,000 at baseline) followed for 10 years to determine sociodemographic and health characteristics associated with the use of these medications between 1986 and 1996. MAIN OUTCOME MEASURES Information about sedative, hypnotic, and antianxiety medication use and demographic and health characteristics was obtained from a race-stratified, probability-based sample of black and white community-dwelling older adults in the Piedmont region of North Carolina during four in-person interviews spanning 10 years. Descriptive statistics were calculated. Logistic regression was used for the final models. RESULTS A total of 13.3% of the subjects were taking these medications in 1986, with the frequency of use declining only to 11.8% in 1996 despite the cohort aging 10 years. Correlates of use at baseline were female gender, white race, depressive symptoms, poor self-rated health, impaired physical function, and health services use. These correlates persisted for each of the three follow-up waves of the survey. In 1996, the odds for being white and using these medications was 4.70 in controlled analyses. CONCLUSIONS Despite the overall decline in the use of sedative, hypnotics, and antianxiety agents in the general population in recent years, over the 10 years of this survey, an aging cohort continued to use these medications at a frequency greater than the general population and did not demonstrate a significant decline in use. Factors unrelated to health status, specifically being white, were among the strongest correlates of use throughout the years of follow-up.

Abstract
This descriptive, retrospective, population-based study assessed patterns of antidepressant medication use in elderly patients in Nova Scotia during fiscal years 1993 through 1996. Individuals > or =65 years of age who were registered with Nova Scotia's Seniors Pharmacare program and filled a prescription for an antidepressant medication during the specified period were included in the study. We determined the number of individuals who filled > or =1 prescription for an antidepressant, the number whose prescription for an antidepressant could be matched with a diagnosis of depression in the physician's billing database, the number who used antidepressants that were judged inappropriate based on published criteria for medication prescribing in the elderly, the number who used a therapeutic antidepressant dose based on published dosing guidelines for the elderly, and the number who used antidepressants for > or =6 months. A total of 12,048, 12,317, and 13,419 individuals filled prescriptions for antidepressants during the 1993 to 1994, 1994 to 1995, and 1995 to 1996 fiscal years, respectively. In each fiscal year, approximately 70% had received a diagnosis of depression based on the International Classification of Diseases, Ninth Revision, Clinical Modification, making it likely that 70% of antidepressant users were receiving these drugs for a primary diagnosis of depression. The number of antidepressant prescriptions that were classified as inappropriate for use in the elderly was 67% in 1993 to 1994, 61% in 1994 to 1995, and 55% in 1995 to 1996. These decreases over time were statistically significant (P < 0.001). Among those using serotonin reuptake inhibitors, secondary tricyclic antidepressants, or tertiary tricyclic antidepressants, 79%, 45%, and 31%, respectively, appeared to be using therapeutic doses. Of 23,553 antidepressant treatment courses, 11,028 (47%) were for < or =180 days. During the study, a significant number of elderly individuals were prescribed antidepressant medications that are judged by expert consensus to be inappropriate for use in this population because of an unfavorable toxicity profile, although the number declined significantly from year to year (P < 0.001 for year-to-year comparisons). Many individuals also appeared to be using antidepressant doses that are probably subtherapeutic, but this finding seemed heavily dependent on the class of antidepressant used. Nearly half of the individuals studied appeared to be treated for inadequately short periods.

Abstract
OBJECTIVE To evaluate the relation between benzodiazepine use and cognitive function among community-dwelling elderly. METHODS This prospective cohort study included 2765 self-reporting subjects from the Duke Established Populations for Epidemiologic Studies of the Elderly. The subjects were cognitively intact at baseline (1986-1987) and alive at follow-up data collection 3 years later. Cognitive function was assessed with the Short Portable Mental Status Questionnaire (unimpaired versus impaired and change in score) and on the basis of the number of errors on the individual domains of the Orientation-Memory-Concentration Test. Benzodiazepine use was determined during in-home interviews and classified by dose, half-life, and duration. Covariates included demographic characteristics, health status, and health behaviors. RESULTS After control for covariates, current users of benzodiazepine made more errors on the memory test (beta coefficient, 0.35; 95% confidence interval [CI], 0.10 to 0.61) than nonusers. Further assessment of the negative effects on memory among current users suggested a dose response in which users taking the recommended or higher dose made more errors (beta coefficient, 0.57; 95% CI, 0.26 to 0.88) and a duration response in which long-term users made more errors (beta coefficient, 0.39; 95% CI, 0.05 to 0.73) than nonusers. Users of agents with long half-lives and users of agents with short half-lives both had increased memory impairment (beta coefficient, 0.32; 95% CI, 0.01 to 0.64 and beta coefficient, 0.38; 95% CI, 0.02 to 0.75, respectively) relative to nonusers. Previous benzodiazepine use was unrelated to memory problems, and current and previous benzodiazepine use was unrelated to level of cognitive functioning as measured with the other 4 tests. CONCLUSIONS The results suggested that current benzodiazepine use, especially in recommended or higher doses, is associated with worse memory among community-dwelling elderly.

Abstract
The pharmacokinetics and pharmacodynamics of the benzodiazepine anxiolytic alprazolam (1 mg orally) were compared between young and elderly healthy volunteers. Eight young subjects (mean age 29.8 years) and eight elderly volunteers (mean age 68.4 years) received oral placebo and alprazolam (1.0 mg) in a randomized, double-blind, single-dose crossover study. In the elderly subjects, plasma concentrations were higher, although not significantly so, than in young volunteers 0.25, 0.5, and 0.75 hours after dosage. Apparent elimination half-life, time of maximum concentration, maximum concentration, volume of distribution, and apparent clearance were similar for the two groups. In both groups, alprazolam treatment (versus placebo) produced significant changes in typical benzodiazepine agonist effects, such as increased sedation and fatigue, reduced excitement, increased feelings of spaciness, and perception of thinking slowed. For some measures, the alprazolam-placebo difference was greater in young than in elderly subjects. In both groups, alprazolam significantly impaired performance on the digit-symbol substitution test (DSST). EEG studies indicated significant increases in relative beta amplitude (13-30 Hz range) after alprazolam compared to placebo. Percent DSST decrement and percent EEG change were highly correlated with plasma alprazolam concentrations for both groups. There were modest increases in alprazolam plasma concentration in the elderly compared to the younger group shortly after drug administration, but there was no evidence of increased sensitivity to the pharmacodynamic effects of alprazolam in the elderly.
