Determinants for the use of psychotropics among nursing home residents

Association between changes in the use of psychotropic drugs and behavioural and psychological symptoms of dementia over 1 year among long-term care facility residents

AIM

Pharmacological treatments are often used in treating the behavioural and psychological symptoms of dementia (BPSD) in nursing homes, despite the fact that non-pharmacological treatments are recommended as a first-line treatment and can provide a suitable alternative. Because the course of BPSD is known to fluctuate depending on individual symptoms over time, the frequencies of drug use and BPSD, as well as their association, should be observed over a longer period. We investigated the association between the changes in psychotropic drug (PD) use and BPSD, focusing on the number of symptoms, severity, and care burden over 1 year among long-term care facility residents.

METHODS

A 1-year follow-up study was conducted among older residents with dementia or similar symptoms (n = 312 at baseline; n = 237 at follow-up) by using a care staff questionnaire in 10 long-term care facilities in Hokkaido, Japan. Medication use was determined based on prescription information. The brief questionnaire form of the Neuropsychiatric Inventory was used to assess BPSD.

RESULTS

Among residents followed up for 1 year, new users of PD-particularly anxiolytics and hypnotics-had a significantly increased number and severity of BPSD, compared with non-PD users. Continuing PDs was also related to increased severity over the year. Among residents with any persistent BPSD for 1 year, new use of PDs-particularly anxiolytics and hypnotics-was significantly associated with an increased care burden of BPSD, compared with the non-use of PDs. The discontinuation of PDs was significantly associated with a decreased care burden, compared with the non-use of PDs.

CONCLUSIONS

Our study suggests that PDs, particularly anxiolytics and hypnotics, may be prescribed carefully in response to exacerbation of BPSD in terms of the number of symptoms, severity, and care burden in long-term care facilities. Continuous monitoring of PDs use and BPSD is important to effectively address BPSD.

Medication use in a cohort of newly admitted nursing home residents (Ageing@NH) in relation to evolving physical and mental health

BACKGROUND

Medication use is high among nursing home (NH) residents, but there is a lack of longitudinal studies, determining medication use at admission and its evolution over time.

AIM

Describing the evolution of the medication use two years after entering a NH, compared to the baseline observations and exploring the relation to the physical and mental health.

METHODS

Data from the observational prospective Ageing@NH study, based on an inception cohort of newly admitted residents at NHs (65+) was used, selecting those consenting and with medication chart available. Information about socio-demographic, functional and mental characteristics, as well as medication use, was collected at baseline, year 1 and year 2.

RESULTS

Medication chart was available for n = 741 at baseline (mean age 83.8, 66% female), and for n = 342 residents in year 2. The mean number of total medications increased from 8.9 to 10.1 (p-value < 0.001). Polypharmacy was high, with an increase in extreme polypharmacy from 23% to 32%. The biggest increase was noted in the respiratory (from 17% to 27%) and alimentary medications (from 80% to 87%). Cardiovascular medication use in year 2, was lower in those with stable high dependency (77%) and those evolving from low to high dependency (79%), than those with stable low dependency (89%) (p < 0.025). For residents with or evolving to dementia symptoms, decline in most medication groups was observed, especially in pain and sleeping medications, while antipsychotics use increased.

CONCLUSION

Although medication use was high, signs of deprescribing were noted when the physical and mental health of the residents declined.

Use of medicines in nursing homes for older people

The National Health Service (NHS) spent £10 billion (40%) of its total budget on people aged 65 and over in 1998/1999. The profile of the health and social care of older people has been raised recently by the publication of the National Service Framework (NSF) for Older People (Department of Health, 2001). The NSF contains standards that older people can expect when they receive health and social care (Box 1). The document also discusses in detail medication management issues in older people. Its two aims in this area are to ensure that older people gain the maximum benefit from their medication in order to maintain or improve quality and duration of life, and do not suffer unnecessarily from illness caused by excessive, inappropriate or inadequate consumption of medicines.

The use of psychotropic drugs for behavioral and psychological symptoms of dementia among residents in long-term care facilities in Japan

OBJECTIVE

To examine whether the use of psychotropic drugs (PDs) was related to behavioral and psychological symptoms of dementia (BPSD) focusing on the prevalence, numbers of symptoms, severity, and care burden among the elderly with BPSD living in long-term care facilities in Japan.

METHOD

We conducted a cross-sectional survey among older people with dementia or similar symptoms (n = 312) using a questionnaire for care staff in 10 selected long-term care facilities. A brief questionnaire form of the Neuropsychiatric Inventory was used to assess BPSD.

RESULTS

PDs were used in 45% among all participants and 47.5% among those exhibiting at least one BPSD. We found that use of PDs was associated with greater numbers, severity, and care burden of BPSD. Also, there was significantly more use of PDs among people who had specific BPSD symptoms, such as delusions, anxiety, and disinhibition, compared with those who did not.

CONCLUSION

The use of PDs among residents in long-term care facilities with dementia or similar symptoms was relatively low compared with previous reports from other countries. Nonetheless, the greater numbers, severity, and care burden of BPSD were associated with the use of PDs.

Associations between conflictual relationships, psychopathology, and the use of psychotropic drugs among older people living in residential facilities

BACKGROUND

Psychiatric symptoms and conflictual relationships (CR) may negatively affect the delivery of care in residential facilities (RF). This study aims to analyze neuropsychiatric symptoms, their correlations with CR among older people living in RF, and their associations with the prescription of psychotropic drugs.

METHODS

A total of 1215 RF residents in five Italian regions were selected for this cross-sectional study. Psychiatric symptoms and CR were assessed with the Neuropsychiatric Inventory and the Resident Assessment Instrument, respectively. Associations between Neuropsychiatric Inventory items, CR, and the use of psychotropic drugs were tested via multiple logistic regressions.

RESULTS

About half (52.7%) of the RF residents experienced one or more clinically relevant neuropsychiatric symptoms. At least one category of CR was reported for 223 residents (19%). Although reciprocal associations were found between different categories of CR, only conflictuality with other residents was associated with the use of antipsychotics (odds ratio (OR) = 2.12). Significant associations were found with irritability (with staff: OR = 2.35; with relatives: OR = 3.09), aberrant motor behaviour (with staff: OR = 2.02), and elation (with relatives: OR = 10.55).

CONCLUSIONS

Neuropsychiatric symptoms and CR are common among RF residents and are reciprocally associated. Further research with longitudinal design is needed to better understand this relationship.

Antipsychotic prescribing in care homes before and after launch of a national dementia strategy: an observational study in English institutions over a 4-year period

OBJECTIVES

To assess associations between the launch of the National Dementia Strategy (NDS) and antipsychotic prescribing in long-term residential care (LTC) in England.

SETTING AND PARTICIPANTS

Retrospective analysis of prescribing patterns in 616 LTC institutions (31 619 residents) following launch of the NDS, using information from electronic medicines management system.

PRIMARY AND SECONDARY OUTCOME MEASURES

Antipsychotic prescribing point prevalence (PP) for all residents in a cross section of LTC settings over a 4-year period following NDS launch. Secondary outcomes included dosages, length of treatment and use of recommended second-generation antipsychotics (SGAs) versus first-generation antipsychotics (FGAs). Associations between facility-level PP values and institutional characteristics, resident demographics were explored. Variations across geographical areas examined. Prescription net ingredient costs calculated.

RESULTS

No statistically significant difference was observed in overall prescribing rates over the 4-year period (Kolmogorov-Smirnov (KS) test p=0.60), and there was no significant shift towards newer SGAs (KS test p=0.32). Dosages were above the maximum indicated in only 1.3% of cases, but duration of prescribing was excessive in 69.7% of cases. Care homes in the highest prescribing quintile were more likely to be located in a deprived area (rate ratio (Q5/Q1) RR=5.89, 95% CI 4.35 to 7.99), registered for dementia (RR=3.38, 95% CI 3.06 to 3.73) and those in the lowest quintile were more likely to be served by a single general practitioner (GP) practice (RR=0.48; 95% CI 0.37 to 0.63); p<0.001 all. A sixfold variation in PP levels was observed between geographical areas. The average annual expenditure on antipsychotics was £65.6 per person resident (2012 prices).

CONCLUSIONS

The NDS in England was not associated with reduced PP levels or the types of antipsychotic prescribing in care homes. Further research is needed to explore why. Clear standards specifying recommended agents, dosages and length of treatment, together with routine monitoring and greater accountability for antipsychotic prescribing, may be required.

Psychotropic Drug Prescription and the Risk of Falls in Nursing Home Residents

BACKGROUND

Falling is a common and serious problem in the elderly. Previous studies suggest that the use of psychotropic drugs increases the risk of falling. However, the contribution of these drugs on fall risk has not been quantified on a daily basis among the general population of nursing homes until now.

OBJECTIVE

To assess the association between fall incidence and the prescription of psychotropic drugs and different categories of psychotropic drugs (antipsychotics, antidepressants, and benzodiazepines) among a general nursing home population.

DESIGN

Retrospective observational study, data collection per person-day.

SETTING

9 nursing homes in Eindhoven, the Netherlands.

PARTICIPANTS

2368 nursing home residents, resulting in 538,575 person-days.

MAIN OUTCOME MEASURE

Association between the prescription of psychotropic drugs and falls.

RESULTS

A total of 2368 nursing home residents were included, which resulted in a data set of 538,575 person-days. Prescription of at least 1 psychotropic drug per day occurred during a total of 318,128 person-days (59.1%). Scheduled prescriptions with or without an as-needed prescription were involved in a total of 270,781 person-days (50.3%). The prescription of psychotropic drugs on a scheduled basis was found to be associated with almost a 3-fold increase in fall incidence (OR 2.88; 95% CI 1.52-5.44). An increase in fall incidence was found following the prescription of antipsychotics (OR 1.97; 95% CI 1.51-2.59) and antidepressants (OR 2.26; 95% CI 1.73-2.95). This increased fall risk was found for prescriptions on a scheduled basis as well as for prescriptions on an as-needed basis.

CONCLUSION

The prescription of psychotropic drugs is associated with a strongly increased risk of falling among nursing home residents. To our knowledge, this is the first study among the general nursing home population in which the association between daily falls and daily prescriptions of psychotropic drugs and groups of psychotropic drugs was specified.

Determinants of Neuroleptic Drug Use in Long-Term Facilities for Elderly Persons

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.

Psychopharmacological medication use among older adults with dementia in nursing homes

Historically, the use of psychopharmacological medications, such as antipsychotic, antidepressant, and anxiolytic agents, have been scrutinized due to concerns with safety and efficacy especially in older adults with dementia. Over the past year, the Centers for Medicare & Medicaid Services launched a national initiative to improve the behavioral health of older adults residing in America's nursing homes with a focus on reducing the inappropriate use of these medications to inform the practitioner of the importance of not just evaluating antipsychotic agents but all medications that an older person with dementia may be prescribed. This is critical due to the increased vulnerability of this population to adverse effects coupled with varying degrees of efficacy. Online national resources are also provided.

Non-pharmacological management of behavioural symptoms of dementia

This article describes a 6-month pilot project in which a community mental health team provided a dementia inreach service into 4 care homes in Birmingham, UK. The project included analysis of the impact of the service at the end of the project as well as a literature review of dementia care in care homes, and especially the issue of antipsychotic medication use and non-pharmacological approaches in managing behavioural and psychological symptoms of dementia (BPSD). The project included training care home staff in the management of BPSD; 2 questionnaires distributed at the beginning of the project found that 65% of care home staff felt a need for education and awareness, practical problem-solving and counselling in managing BPSD. Self-reported knowledge of common mental health problems and dementia increased in care home staff at the end of the project by a margin of 7% and 11% respectively. Reported confidence in managing behavioural problems increased by 9% among care home staff at the end of the project. The project achieved regular monitoring of psychotropic medications, and enabled the discharge of 14 out of 63 existing patients in the selected homes. The project also provided guidance for non-pharmacological techniques for management of BPSD, which included relaxation techniques, distraction techniques, reality orientation, reminiscence work, needs led therapy, music therapy, person-centred approach and behaviour therapy.

Psychotropic medication use in canadian long-term care patients referred for psychogeriatric consultation

Background and Puspose

Prior studies have shown a high prevalence of psychotropic medication use among patients residing in long-term care homes (LTCHs). The purpose of this study was to examine psychotropic medication use by LTCH patients in a metropolitan Canadian city referred to outreach teams for psychiatric assessment.

Methods

A retrospective review of charts from specialized psychogeriatric outreach teams serving a large metropolitan city in Canada was undertaken. Data from 68 charts were reviewed. Data were analyzed using descriptive and correlational statistics.

Results

Antipsychotic medications were the most frequent drugs prescribed to patients referred for psychogeriatric assessment (55.9%), followed by antidepressants (50.0%), cognitive enhancers (44.1%) and benzodiazepines (29.4%). More than a quarter of patients (26.5%) were on three psychotropic medications. Medications were adjusted in 35.3% of cases mostly resulting in dose increases. Only 5.9% of patients had their medication dose reduced.

Conclusions

This preliminary exploratory study suggests that patients referred to specialized outreach teams may be a difficult-to-treat population. Further studies are required to establish effective prescribing practices and service delivery models.

Reasons for psychiatric medication prescription for new nursing home residents

OBJECTIVES

This article focuses on justification of psychoactive medication prescription for NH residents during their first three months post-admission.

METHOD

We extracted data from 73 charts drawn from a convenience sample of individuals who were residents of seven nursing homes (NHs) for at least three months during 2009. Six focus groups with NH staff were conducted to explore rationales for psychoactive medication usage.

RESULTS

Eighty-nine percent of the residents who received psychoactive medications during the first three months of residence had a psychiatric diagnosis, and all residents who received psychoactive medications had a written physician's order. Mental status was monitored by staff, and psychoactive medications were titrated based on changes in mental status. One concern was that no Level II Preadmission Screening and Annual Resident Review (PASRR) evaluations were completed during the admissions process. Further, while 73% had mental health diagnoses at admission, 85% of the NH residents were on a psychoactive medication three months after admission, and 19% were on four or more psychoactive medications. Although over half of the residents had notes in their charts regarding non-psychopharmacological strategies to address problem behaviors, their number was eclipsed by the number receiving psychopharmacological treatment.

CONCLUSIONS

While the results suggest that NHs may be providing more mental health care than in the past, psychopharmacological treatment remains the dominant approach, perhaps because of limited mental health training of staff, and lack of diagnostic precision due to few trained geriatric mental health professionals. A critical review of the role of the PASRR process is suggested.

Prevalence and predictors of antidepressant prescribing in nursing home residents in the United States

BACKGROUND

Late-life depression is a common psychiatric disorder associated with increased morbidity and mortality. Depression is often under-detected and undertreated in elderly nursing home residents.

OBJECTIVES

The aim of this study was to examine the prevalence of antidepressant drug use and to identify the factors associated with its use among elderly nursing home residents.

METHODS

The study involved the analysis of a nationally representative sample of prescription and resident files from the 2004 National Nursing Home Survey (NNHS). The study sample included all elderly nursing home residents ≥65 years of age. The analysis focused on prescribing from any antidepressant class, including selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants (TCAs), serotonin modulators, serotonin-norepinephrine reuptake inhibitors (SNRIs), monoamine oxidase inhibitors (MAOIs), and others. Descriptive weighted analysis was performed to examine antidepressant use prevalence patterns in elderly nursing home residents. Multiple logistic regression analysis within the conceptual framework of Anderson's behavioral model was used to examine the predisposing, enabling, and need characteristics associated with antidepressant use.

RESULTS

According to the 2004 NNHS, overall prevalence of antidepressant use among elderly nursing home residents was 46.22% (95% CI, 45.16-47.27). Most antidepressant users were ≥85 years of age (49.7%), female (75.7%), non-Hispanic (96.4%), and white (91.1%). The most prescribed class of antidepressants was SSRIs (31.09%; 95% CI, 30.12-32.07), followed by serotonin modulators (4.65%; 95% CI, 4.22-5.09), SNRIs (2.78%; 95% CI, 2.45-3.12), TCAs (2.34%; 95% CI, 2.03-2.65), and MAOIs (0.01%; 95% CI, 0.00-0.03). Citalopram (12.92%; 95% CI, 12.21-13.63) was the most prescribed individual antidepressant, followed by mirtazapine (10.19%; 95% CI, 9.55-10.84). Among the predisposing characteristics, age, race, and marital status were significantly associated with antidepressant use. The odds of receiving an antidepressant were lower for those aged ≥85 years and those who were unmarried elderly residents, when compared with their counterparts; whites were more likely to receive an antidepressant than nonwhites. Enabling factors such as Medicaid and bed capacity significantly predicted antidepressant use. Having Medicaid was positively associated with antidepressant prescription, whereas an increase in the total number of beds decreased the probability of an antidepressant prescription. Among need characteristics, the likelihood of antidepressant prescription use decreased with increased dependence in decision-making ability and out-of-bed mobility. The presence of depressed mood indicators and a history of falls/fractures increased the likelihood of antidepressant prescription use. The odds of receiving an antidepressant increased with diagnosis of depression but decreased with diagnosis of anxiety.

CONCLUSION

Nearly half of elderly nursing home residents received antidepressants. In addition to need factors, predisposing and enabling factors played an important role in influencing the use of antidepressants in elderly nursing home residents.

Prevalence of psychotropic medication use among German and Austrian nursing home residents: a comparison of 3 cohorts

BACKGROUND

Despite increasing knowledge about the limited effectiveness and severe adverse effects, the prescription rate of psychotropic medications in frail elderly persons remains high. Prescriptions are mainly made to control behavioral and psychological symptoms of dementia, although factors associated with prescriptions are rarely reported. However, such information is a prerequisite to develop intervention programs aiming to safely reduce psychotropic medication in nursing home residents.

METHODS

We report the comparison of cross-sectional data of psychotropic medication prescription rates from 3 large studies including nursing home residents in Germany and Austria. We aimed to compare the prevalence of (1) psychotropic medication, (2) different classes of psychotropic medication, (3) psychotropic medication administered for bedtime use, and (4) associations between prescription of psychotropics and institutional and residents' characteristics. Confidence intervals of prevalences and multiple logistic regression analyses were adjusted for cluster correlation.

RESULTS

Data from 5336 residents in 136 long term care facilities were included. In Austria, 74.6% (95% CI 72.0-77.2%) of all residents had a prescription of at least one psychotropic medication compared to Germany with about 51.8% (95% CI 48.3-55.2%) and 52.4% (95% CI 48.7-56.1%). Of all antipsychotics, 66% (Austria) and 47% (Germany) were prescribed for bedtime use. Most prescriptions were conventional, low-potency antipsychotics. In all 3 studies, there was no statistically significant association between psychotropic medication prescription and nursing home characteristics. On the level of residents, consistent positive associations were found for higher level of care dependency and permanent restlessness. Consistent negative associations were found for older age and male gender.

CONCLUSION

Frequency of psychotropic and especially antipsychotic medication is substantial in nursing home residents in Germany and Austria. The high number of prescriptions is likely to be an indicator for a perceived or actual lack of strategies to handle behavioral and psychological symptoms of dementia.

Correlations of nursing home characteristics with prescription of osteoporosis medications

BACKGROUND

Osteoporosis is highly prevalent in the nursing home (NH) populations but medications that increase bone mineral density are used infrequently. Prior research finds few patient characteristics predict treatment. NH characteristics have been associated with prescription of some medications. We examined associations of NH-level characteristics with osteoporosis treatment in elderly patients admitted to a NH after a fracture.

METHOD

We conducted a cohort study of patients with hip, wrist and humeral fractures admitted to a NH in NJ. They were followed for 12 months from 1999 to 2004. Possible NH-level predictors of receiving osteoporosis treatment were assessed in mixed multivariable models to account for clustering within individual NHs.

RESULTS

Of the 2838 post-fracture patients identified from 180 NHs, 156 (5.5%) were prescribed an osteoporosis medication. There was wide variation in treatment between individual NHs (0-40%), which was substantially reduced after adjusting for patient case mix. Several patient characteristics did associate with osteoporosis treatment-female gender (odds ratio (OR) 2.56, 95% confidence interval (CI) 1.42, 4.61), younger age per year (OR 0.98, 95%CI 0.96, 0.99), white race (OR 2.37, 95%CI 1.23, 4.56) and prior history of fracture (OR 4.41, 95%CI 1.04, 18.73). However no NH characteristics significantly associate with treatment (profit status, NH chain member, occupancy rate, and bed size).

CONCLUSION

NH characteristics did not predict pharmacological treatment of osteoporosis. Further studies of osteoporosis prescribing in NHs need to consider other types of variables as possible correlates of prescribing.

Geriatric drug utilisation of psychotropics in Belgian nursing homes

OBJECTIVE

To determine the prevalence of psychotropic drug use in Belgian nursing homes, in relation to residents' and institutional characteristics.

METHODS

The PHEBE project (Prescribing in Homes for the Elderly in Belgium, 2005) was a cross-sectional study, investigating drug use in 76 nursing homes. Psychotropics were categorised into antidepressants, antipsychotics, benzodiazepines and anti-dementia drugs using the ATC classification.

RESULTS

Residents' mean age (n=1730) was 85 (SD: 8) years and 78% were female. The overall prevalence of psychotropic drug use among nursing home residents was 79%. Benzodiazepines were used by 54% and antipsychotics by 33% of all residents. Residents received a higher number of antipsychotics ( p<0.001) but fewer antidepressants (and other medicines) with increasing severity of dementia. Antidepressants were prescribed in 40% of which 2/3 was indicated for depression and 1/3 for insomnia. Anti-dementia drugs were used by 8%. Institutional characteristics showed no relationship with psychotropic drug use, except for a lower use when medication was dispensed by a hospital pharmacist (p=0.001).

CONCLUSION

As in other European countries, the prevalence of psychotropic utilisation in Belgian nursing homes is exceedingly high, with excessive duplicate use. Guidelines, education and clinical practice recommendations focusing on initiation, reassessment and withdrawal of psychotropic therapy, are needed.

Changes to psychotropic medications in the six months after admission to nursing homes in Melbourne, Australia

BACKGROUND

Nursing home residents are often prescribed large numbers of psychotropic medications. Previous studies suggest that antipsychotic medications are often unnecessary and can be withdrawn without ill effects. Depression, in contrast, is believed to be under-recognized and under-treated.

METHOD

A six-month audit was carried out of the antipsychotic, antidepressant, anxiolytic and hypnotic medications prescribed to 166 newly admitted residents of a convenience sample of seven nursing homes in Melbourne, Australia.

RESULTS

Over the six-month period, antidepressants were started in 6% of all cases and stopped in 2% of treated cases. Antipsychotics were added in 5% of all cases and stopped in 15% of treated cases. Residents were switched from one antidepressant to another in 5% of treated cases and from one antipsychotic to another in 4%. Benzodiazepine use was relatively modest.

CONCLUSIONS

Judging from epidemiological data, treatment revisions were almost certainly insufficient to address residents' mental health needs. We discuss ways of harnessing existing nursing and pharmacy resources to ensure better care for aged residents.

Withholding, discontinuing and withdrawing medications in dementia patients at the end of life: a neglected problem in the disadvantaged dying?

Recent years have seen a growing recognition that dementia is a terminal illness and that patients with advanced dementia nearing the end of life do not currently receive adequate palliative care. However, research into palliative care for these patients has thus far been limited. Furthermore, there has been little discussion in the literature regarding medication use in patients with advanced dementia who are nearing the end of life, and discontinuation of medication has not been well studied despite its potential to reduce the burden on the patient and to improve quality of life. There is limited, and sometimes contradictory, evidence available in the literature to guide evidence-based discontinuation of drugs such as acetylcholinesterase inhibitors, antipsychotic agents, HMG-CoA reductase inhibitors (statins), antibacterials, antihypertensives, antihyperglycaemic drugs and anticoagulants. Furthermore, end-of-life care of patients with advanced dementia may be complicated by difficulties in accurately estimating life expectancy, ethical considerations regarding withholding or withdrawing treatment, and the wishes of the patient and/or their family. Significant research must be undertaken in the area of medication discontinuation in patients with advanced dementia nearing the end of life to determine how physicians currently decide whether medications should be discontinued, and also to develop the evidence base and provide guidance on systematic medication discontinuation.

Sedative load and mortality among residents of long-term care facilities: a prospective cohort study

BACKGROUND

Older people are often prescribed multiple drugs with sedative properties. Most research has focused on specific classes of sedative and psychotropic drugs. The cumulative effect of taking multiple drugs with sedative properties has been termed 'sedative load'. Few previous studies have investigated the sedative load among residents of long-term care facilities. No previous studies have assessed the possible association between sedative load and mortality.

OBJECTIVE

The objective of this study was to describe the sedative load among residents of long-term care facilities, and to investigate a possible association between sedative load and mortality.

METHODS

This was a prospective cohort study. The study population comprised all 1444 residents of 53 long-term care wards in seven hospitals in Helsinki during September 2003. Of the eligible residents, 1087 residents or their proxies provided written informed consent to participate. Medical, medication and follow-up mortality data were available for 1004 residents. The main outcome measures were sedative load and all-cause mortality.

RESULTS

The mean age of the residents was 81.3 (SD 10.9) years, and the mean number of regularly used drugs per resident was 7.1 (SD 3.4). Fifteen percent of residents were categorized as non-users of sedative drugs, 32% as users of some drugs with sedative properties and 53% as residents with a high sedative load. There was a bivariate association between having a higher sedative load and younger age (p < 0.001), male sex (p = 0.006), not being widowed (p = 0.001), diagnosis of depression (p < 0.001), diagnosis of psychiatric illness other than depression (p < 0.001), not being diagnosed with dementia (p = 0.009) and a shorter duration of institutional care (p = 0.02). Unadjusted analysis revealed that having a higher sedative load was associated with increased survival (p = 0.04, log rank test). However, in the adjusted Cox proportional hazard model, only poor nutritional status (hazard ratio [HR] 1.55; 95% CI 1.32, 1.82), male sex (HR 1.37; 95% CI 1.12, 1.69), increasing age (HR 1.04; 95% CI 1.03, 1.05) and co-morbidity (HR 1.07; 95% CI 1.02, 1.13) were significantly associated with risk of death.

CONCLUSIONS

There is a very high rate of sedative and psychotropic drug use among residents of long-term care facilities in Helsinki. However, having a high sedative load was not associated with an increased risk of death. Further research is needed to investigate the possible association between sedative load and mortality using alternative models and methods, and in different resident populations.

Psychotropic medication use among nursing home residents in Austria: a cross-sectional study

Background

The use of psychotropic medications and their adverse effects in frail elderly has been debated extensively. However, recent data from European studies show that these drugs are still frequently prescribed in nursing home residents. In Austria, prevalence data are lacking. We aimed to determine the prevalence of psychotropic medication prescription in Austrian nursing homes and to explore characteristics associated with their prescription.

Methods

Cross-sectional study and association analysis in forty-eight out of 50 nursing homes with 1844 out of a total of 2005 residents in a defined urban-rural region in Austria. Prescribed medication was retrieved from residents' charts. Psychotropic medications were coded according to the Anatomical Therapeutic Chemical Classification 2005. Cluster-adjusted multiple logistic regression analysis was performed to investigate institutional and residents' characteristics associated with prescription.

Results

Residents' mean age was 81; 73% of residents were female. Mean cluster-adjusted prevalence of residents with at least one psychotropic medication was 74.6% (95% confidence interval, CI, 72.0–77.2). A total of 45.9% (95% CI 42.7–49.1) had at least one prescription of an antipsychotic medication. Two third of all antipsychotic medications were prescribed for bedtime use only. Anxiolytics were prescribed in 22.2% (95% CI 20.0–24.5), hypnotics in 13.3% (95% CI 11.3–15.4), and antidepressants in 36.8% (95% CI 34.1–39.6) of residents. None of the institutional characteristics and only few residents' characteristics were significantly associated with psychotropic medication prescription. Permanent restlessness was positively associated with psychotropic medication prescription (AOR 1.54, 95% CI 1.32–1.79) whereas cognitive impairment was inversely associated (AOR 0.70, 95% CI 0.56–0.88).

Conclusion

Frequency of psychotropic medication prescription is high in Austrian nursing homes compared to recent published data from other countries. Interventions should aim at reduction and optimisation of prescriptions.

Antipsychotic drug use among elderly nursing home residents in the United States

BACKGROUND

Antipsychotic utilization in elderly nursing home residents has increased substantially in recent years, primarily due to the use of atypical antipsychotic agents. However, few studies have examined antipsychotic utilization patterns in nursing home residents in the United States since the introduction of atypical agents in the 1990s.

OBJECTIVE

The goal of this study was to examine the prevalence of and the factors associated with antipsychotic drug use among elderly nursing home residents in the United States.

METHODS

This study involved a cross-sectional analysis of prescription and resident data files from the 2004 National Nursing Home Survey (NNNHS). The analysis focused on the use of 11 typical and 6 atypical antipsychotic agents among a nationally representative sample of elderly patients (aged > or =65 years). Descriptive weighted analysis was performed to examine antipsychotic prevalence patterns. Multiple logistic regression analysis within the conceptual framework of the Andersen behavioral model was used to examine the factors associated with antipsychotic drug use among the elderly nursing home residents.

RESULTS

According to the 2004 NNHS, 0.32 million elderly nursing home residents received antipsychotic medications, for an overall prevalence of 24.82%. Most received atypical agents (23.45%), while 1.90% received typical agents. Frequently reported diagnoses among the elderly using an antipsychotic agent were dementia (70%), depression (41%), and anxiety (18%). Among the predisposing characteristics, female gender and age (> or =85 years) were negatively associated with antipsychotic drug use. Need factors such as increasing dependence in decision-making ability regarding tasks of daily life, depressed mood indicators, behavioral symptoms, history of falls, and bowel incontinence were positively associated with antipsychotic drug use. In addition to the use of antipsychotic agents in schizophrenia and bipolar mania, this study found high use in conditions such as dementia, anxiety, depression, and parkinsonism in the elderly.

CONCLUSIONS

Nearly 1 in 4 elderly nursing home residents in the United States received antipsychotic agents. Predisposing and need factors played a vital role in determining the use of antipsychotic agents in these elderly patients. Overall, the study findings suggest that there is a need to monitor antipsychotic drug use by elderly patients in US nursing homes in light of recent efficacy and safety data on atypical agents.

Does the presence of a dementia special care unit improve nursing home quality?

OBJECTIVE

This study quantifies the effect of a new dementia special care unit (D-SCU) on the provision of care to all residents in a nursing home (NH).

METHOD

The authors use data from the On-line Survey Certification and Reporting system to identify free-standing NHs that first reported a D-SCU between 1996 and 2003 (N = 1,519). Fixed-effects models estimate the effect of a new D-SCU on the prevalence of each outcome (physical restraints, feeding tubes, and psychotropic medications) while controlling for secular trends.

RESULTS

For all NHs, the use of physical restraints declined, the use of antipsychotics increased, and other measures remained relatively constant. The introduction of a D-SCU was not associated with changes in trends for any measure.

DISCUSSION

Differences in care processes between NHs with and without D-SCUs are the result of differences in their underlying approach to care, not the result of care practice diffusion from the D-SCU.

Stopping antipsychotic drug therapy in demented nursing home patients: a randomized, placebo-controlled study--the Bergen District Nursing Home Study (BEDNURS)

BACKGROUND

Despite modest efficacy, unpredictable individual utility, and a high rate of adverse effects, behavioural and psychological symptoms of dementia (BPSD) are common determinants for antipsychotic drug therapy in nursing home patients.

AIMS

To explore the impact on BPSD of stopping long-term antipsychotic treatment in nursing home patients with dementia.

METHODS

Fifty-five patients (43 women; mean age 84.1) taking haloperidol, risperidone, or olanzapine for BPSD were randomly assigned to cessation (intervention group, n=27) or continued treatment with antipsychotic drugs (reference group, n=28) for 4 consecutive weeks. The Neuropsychiatric Inventory (NPI) Questionnaire was used to examine changes in behavioural and psychological symptoms.

RESULTS

By study completion, 23 of the 27 intervention group patients were still off antipsychotics. Symptom scores (NPI) remained stable or even improved in 42 patients (intervention group, 18 out of 27; reference group, 24 out of 28; p=0.18). As compared to patients with stable or improved symptom scores, patients with behavioural deterioration after antipsychotic cessation used higher daily drug doses at baseline (p=0.42).

CONCLUSION

A large share of elderly nursing home patients on long-term treatment with antipsychotics for BPSD, do well without this treatment. Standardized symptom evaluations and drug cessation attempts should therefore be undertaken at regular intervals.

Clinical diagnosis of dementia, not behavioral and psychologic symptoms, is associated with psychotropic drug use in community-dwelling elders classified as having dementia

Little is known about the prevalence and correlates of psychotropic drug use in community-dwelling elders with dementia. Baseline data from 285 community-dwelling elders with a research classification of dementia enrolled in the observational Memory and Medical Care Study were analyzed. Of these, 33.3% with a research classification of dementia were clinically diagnosed, 28.8% used at least 1 psychotropic drug, and 61.8% had at least 1 behavioral or psychologic symptom of dementia. Presence of a behavioral or psychologic symptom of dementia was associated with a higher likelihood of a clinical diagnosis of dementia. A clinical diagnosis of dementia, not a behavioral or psychologic symptom of dementia, was associated with psychotropics use. Clinical recognition of dementia appears to be an intermediate step between presence of symptoms of dementia and the prescription of psychotropics. Most community-dwelling elders meeting the research criteria for dementia were not clinically diagnosed, despite contact with a physician (89%) in the previous year.

CNS-active drugs in aging population at high risk of cerebrovascular events: evidence from preclinical and clinical studies

The recovery process following cerebral insults such as stroke is affected by aging and pharmacotherapy. The use of medication including CNS-active drugs has increased in the elderly during recent years. However, surprisingly little is known about how safe they are with respect to severity of sensorimotor and cognitive impairments or recovery of function following possible cerebrovascular accidents. This review examines the experimental and clinical literature, primarily from 1995 onwards, concerning medication in relation to cerebrovascular events and functional recovery. Special attention is directed to polypharmacy and to new CNS-active drugs, which the elderly are already taking or are prescribed to treat emerging, stroke-induced psychiatric symptoms. The neurobiological mechanisms affected by these drugs are discussed.

Neither atypical nor conventional antipsychotics increase mortality or hospital admissions among elderly patients with dementia: a two-year prospective study

BACKGROUND

Antipsychotics are widely used to manage behavioral disorders in patients with dementia. Recently, serious concerns have been raised about the stroke and mortality risk of atypical antipsychotics when administered to patients with dementia.

AIM

The aim of this study was to examine the impact of atypical and conventional antipsychotics on mortality and hospital admissions among Finnish elderly institutionalized patients with dementia in a two-year follow up and to compare their prognosis with that of nonusers.

PATIENTS AND METHODS

The authors examined 254 very frail patients with dementia, mean age 86 years, from seven Finnish nursing homes and two hospitals in 1999-2000. Medical records provided information on the use of daily antipsychotic medication; central registers confirmed mortality for up to two years.

RESULTS

Nearly one-half (48.4%) of the patients used antipsychotic medication: 37.4% received conventional neuroleptics (N = 95) and 11.0% received atypical antipsychotics (N = 28). The mean number of hospital admissions was higher among the nonusers than among the users of conventional or atypical antipsychotics. Of the users of atypical antipsychotics (risperidone, olanzapine), 32.1% died within 2 years. The respective figures for users of conventional neuroleptics were 45.3%, and for the nonusers, 49.6%. In the Cox proportional hazard model, a high number of medications and the use of physical restraint predicted higher mortality at two years. The use of atypical antipsychotics showed lower risk of mortality, if any. The respective test for conventional antipsychotics was nonsignificant.

CONCLUSION

Among these frail and very old patients with dementia, neither the use of atypical antipsychotics nor the use of conventional neuroleptics increased mortality or hospital admissions. The use of restraints, however, doubled the risk of mortality.

Clinical diagnosis of dementia, not presence of behavioral and psychological symptoms, is associated with psychotropic use in community-dwelling elders classified as having dementia

Little is known about the prevalence and correlates of psychotropic use in community-dwelling elders with dementia. Baseline data from 285 community-dwelling elders with a research classification of dementia (based on a neuropsychological battery of 4 tests) and their knowledgeable informants enrolled in the observational Memory and Medical Care Study were analyzed. A total of 33.3% of subjects with a research classification of dementia were clinically diagnosed, 28.8% used at least 1 psychotropic drug, and 61.8% had at least 1 behavioral or psychological symptom of dementia (BPSD). Presence of BPSD was associated with a higher likelihood of a clinical diagnosis of dementia. Multivariate logistic regression showed a clinical diagnosis of dementia, not BPSD, was associated with psychotropic use; clinical recognition of dementia appears to be an intermediate step between presence of BPSD and prescription of psychotropics. In addition, most community-dwelling elders meeting the research criteria for dementia were not clinically diagnosed, despite contact with a physician (89%) in the previous year.

Factors influencing psychotropic prescription by non-psychiatrist physicians in a nursing home for the elderly in Brazil

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.

Factors Associated With Psychotropic Drug Usage Among Nursing Home Residents With Dementia

BACKGROUND

Although federal regulations hold nursing homes responsible for monitoring psychotropic drug (PD) usage, there is a high prevalence of PD usage and significant variation in use across nursing homes.

OBJECTIVES

The aims of study were to (a) describe current PD usage in nursing homes and (b) examine resident and nursing home factors associated with PD usage in nursing home residents with dementia.

METHODS

A multivariate, multisite, cross-sectional descriptive study was used on data from 107 dementia patients residing in nine randomly selected nursing homes in southeastern Michigan. The PD usage of interest included antipsychotics, antidepressants, anxiolytics or sedatives, and mood stabilizers. Regression analysis tested resident factors, including cognitive ability, functional ability, presence of depressive symptoms, and demographic characteristics, and three facility factors (nursing home size, type of ownership, and level of registered nurse [RN] staffing) in comparison with PD usage.

RESULTS

In this study, 67.3% of the participants received at least one PD. The most frequently prescribed PDs were antidepressants (41.1%) and antipsychotics (37.4%). Newly developed antipsychotics such as risperidone were given more frequently to residents than were conventional drugs such as haloperidol. Regression analysis suggests that the presence of depressive symptoms (odds ratio [OR]= 3.5, p < .01) and low levels of RN staffing (OR = 1.0, p < .01) were associated with the use of PD.

DISCUSSION

Psychotropic drugs are prescribed frequently for nursing home residents, although such usage is variable. Behavioral symptoms were not an independent predictive factor for PD use. Rather, combined resident and facility characteristics best predicted the use of PDs in nursing home residents. The evaluation of nursing home systems for these characteristics as predictive factors for PD usage in nursing home patients with dementia is suggested by the results. Likewise, attention to new drugs such as selective serotonin reuptake inhibitors and their appropriate use is recommended.

Use of antipsychotic medications among elderly residents in long-term institutional care: a three-year follow-up

OBJECTIVE

To analyse the use of antipsychotic medications, change over time and associated factors in a three-year follow-up among elderly residents in long-term institutional care.

DESIGN

Retrospective study was designed with three identical cross-sectional samples originating from the same long-term care facilities, and collected 1 July to 31 December in 2001, 2002 and 2003, in Finland. These were extracted from the Resident Assessment Instrument (RAI) database, based on Minimum Data Set (MDS) assessments.

SETTING

Of the data providers 16 were hospital-based institutions and 25 residential homes.

PARTICIPANTS

Each of the data sets included 3,662-3,867 resident assessments.

RESULTS

The prevalence use of one or more antipsychotic decreased from 42% in 2001 to 39% in 2003. The overall confounder-adjusted decrease in antipsychotic use was not statistically significant. However, the use of antipsychotics decreased among residents who had wandering as a behavioural problem (OR 0.79, 95% CI 0.63-0.99) and increased among residents with concomitant use of anxiolytic medications (OR 1.23, 95% CI 1.03-1.48).

CONCLUSIONS

The use of antipsychotic medications among residents in long-term institutional care was common and the caring patterns were quite stable during the observation period. Adequate indications may not have been achieved in all cases. More attention should be paid to the appropriate use of antipsychotics in this frail population.

Prevalence of insomnia and its associated factors in elderly long-term care residents

Insomnia is a significant problem that may jeopardize elderly residents' quality of life in long-term care settings. However, there are only a few studies dealing with sleeping disturbances among nursing home residents. The goal of this study was to determine the prevalence of insomnia and its associated factors in nursing home residents. A cross-sectional study (n=2332) was conducted among seniors living in long-term care facilities. The findings indicate that 144 (6.2%) participants had an insomnia disorder according to DSM-IV criteria, 17% displayed at least one symptom of insomnia, and more that half of the subjects were benzodiazepine users. According to multivariate analysis, psychological distress (adjusted odds ratio=1.51) and disruptive behaviors (adjusted odds ratio=2.10) were the only factors associated with an insomnia disorder among this population. In conclusion, insomnia is a fairly important problem, as a symptom or a syndrome, among elderly people and deserves attention from caregivers. Alternative interventions to benzodiazepine drugs, which are suited to long-term care residents while tailored to these specific care settings, should be developed.

From psychophysiological insomnia to organic sleep disturbances: a continuum in late onset insomnia - with special concerns relating to its treatment

The population suffering from insomnia in old age onset (LOI) is quite large. LOI might include a larger scale of syndromes ranging from typical psychophysiological insomnia to night delirium. The correlation between the biological, biochemical changes and the quantitative as well as the qualitative alterations of the sleep process through aging has not been fully explored. One can suppose that any cerebral lesion leading to a dysfunction in mental performance can also act on the sleep. The majority of LOI brain metabolic disturbances might therefore have some etiological role. The authors suggest the application of this concept in the clinical evaluation of LOI. The authors constructed a heuristic model for the pathophysiology and treatment of LOI. It is a bipolar axis containing the most typical symptoms of LOI. On the opposite margins psychophysiological insomnia and organic/metabolic insomnia (up to delirious states) are settled. The position on the axis (i.e., its distance from the "edge syndromes") gives information on the probability of its organic nature. Based on their clinical experiences and considering the data of the very few studies, they suppose that with the help of a detailed analysis of the symptoms of LOI and using some additional (electrophysiological and neuroimaging) laboratory methods most patients with LOI can get a strict diagnostic position on the LOI axis. Using the LOI axis not only a detailed evaluation of the symptomatology but also more sophisticated therapeutic interventions become possible. Symptoms on the "metabolic side" can be cured by a single evening application of any drugs improving the function of the brain (like nootropics, neuroprotective agents or even slight stimulants, e.g., caffeine) might show a "paradoxical hypnotic" effect, or in combination with sleeping pills they can cause an additive effect in LOI patients. The efficacy of this treatment can also have a diagnostic value: i.e., it helps to differentiate between the primary (organic) and psychophysiological (exogenous or emotional/psychic) forms of LOI.

Prevalence of psychotropic drug use in nursing homes for the aged in Quebec and in the French-speaking area of Switzerland

BACKGROUND

The use of psychotropic drugs is high in institutionalised elderly, which raises the question of its appropriateness. This study aimed to: (1) estimate the use of psychotropics, for each family, in terms of the prevalence and dosage among the elderly in nursing homes in French-speaking Switzerland and Quebec; and (2) assess, for each family of psychotropic drugs and for each care facility, the prevalence of use and departure from average prescription (ratio of observed-to-expected prevalence).

METHOD

An administrative database was used for this cross-sectional analysis. The sample included 8183 Quebec and 7592 Swiss long-term care residents. Three classes of psychotropics (antipsychotics, antidepressants, hypnotics-anxiolytics) were defined as dichotomous variables. Logistic regressions were conducted to identify residents characteristics associated with the use of each psychotropic type and to compute expected prevalence.

RESULTS

Swiss residents were slightly older and less dependent than Quebec residents. Use of psychotropic drugs was higher in Swiss than in Quebec residents, on the whole as well as for each family of drug. A total of 78.1% of Swiss residents used at least one drug as compared to 66.9% in Quebec. Ninety percent of residents were given less than 7 defined daily doses per week, irrespective of the drug family. According to Beer's criteria, only 4.9% of prescriptions were inadequate. In Quebec and in Switzerland, the prevalence of antidepressant use was associated with the prevalence of hypnotic-anxiolytic use. No ratios of observed-to-expected reached statistical significance.

INTERPRETATION

There was a considerable use of psychotropics in Quebec and Switzerland with, seemingly, no dramatic departure from the average practice. Our data cannot tell if there is a global overuse of psychotropics, but indicated that dosage and medication selection seem adequate. Physicians should critically reassess the necessity of prescribed medications for their patients.

Perceived anxiety, depression, and sleeping problems in relation to psychotropic drug use among elderly in assisted-living facilities

OBJECTIVE

The aim of the present study was to investigate the perceived anxiety, depression, sleeping habits, and participation in social activities in relation to psychotropic drug use among elderly in assisted-living facilities and to identify factors of importance for the use of these drugs.

METHOD

The study had a cross-sectional design and included 93 residents living in old-age homes or in nursing homes in a municipality in southern Sweden. Data regarding medication was obtained from medical records and included all psychoactive drugs. The perceived anxiety, depression and sleeping habits of the residents were assessed using a structured interview questionnaire.

RESULTS

Many of the residents had sleeping problems and also reported problems concerning anxiety and depression. Of the study population, 65 (70%) used one or more psychoactive drug; 9 were prescribed neuroleptics (10%), 29 anxiolytics (31%), 43 hypnotics (43%) and 31 were prescribed anti-depressants (33%). The most commonly used psychotropic drugs as it related to the residents' problems were: benzodiazepines (oxazepam) against anxiety, benzodiazepine-related agents (zoldipem and zopiclon) against insomnia and serotonin reuptake inhibitors (SSRI; citalopram) against depression. The residents who had been treated with psychotropic drugs at home continued this treatment after moving to assisted-living facilities and approximately 30% of the residents were prescribed new psychotropic drugs. Of those that perceived anxiety, insomnia or felt depressed, between 58% and 69%, respectively, had spoken to neither a nurse nor a physician about these problems. Of those that had talked to a nurse/physician about these problems, a majority had been prescribed psychotropic drugs. Factors of importance for treatment with psychotropic drugs against anxiety, insomnia and depression were: prior treatment with these drugs at home and discussing their problems with a physician.

CONCLUSION

The communication between the residents and the nurses/physicians appears to be insufficient as the residents state that they have not discussed their problems with a nurse or a physician and that the prescription of psychotropic drugs does not seem to be in proportion to the residents' perceived problems.

Vocally disruptive behaviour in dementia: development of an evidence based practice guideline

Vocally Disruptive Behaviour (VDB) is a term that includes screaming, abusive language, moaning, perseveration, and repetitive and inappropriate requests. It is one of the most challenging behaviours for nursing home staff, caregivers for people with dementia, and other nursing home residents. As with other behavioural disturbances, multiple causal factors have been identified in the literature and individual cases may have a number of interacting factors. There is a lack of consensus about how to treat VDB. Systematic treatment studies are few and there is a lack of empirical data supporting the effectiveness of specific interventions commonly used in clinical practice. This hinders clinicians and may result in the use of inappropriate treatments. Our aim was to systematically review the literature in order to develop a practice guideline for the assessment and management of VDB. The review will examine the typology, risk factors and management of VDB.

Use of Psychotropic Drugs in Elderly Nursing Home Residents with and without Dementia in Helsinki, Finland

OBJECTIVE

Use of psychotropic medication is very common in nursing home residents. Our objective was to describe the use of psychotropic drugs in all long-term nursing home residents > or =65 years of age with and without dementia in Helsinki, Finland.

METHOD

The study was a cross-sectional assessment of the nursing home population. The residents' health status was assessed and data on their demographic factors, health and medication use were collected from medical charts in February 2003.

RESULTS

Of all nursing home residents in Helsinki, 82% (n = 1987) participated in the study. The nursing home residents' mean age was 83.7 (SD 7.7) years, 80.7% were female, and 69.5% were diagnosed with dementia. The mean number of drugs [corrected] given regularly was 7.9 (SD 3.6) per day per resident[corrected] Of the participants, 79.7% were regularly taking psychotropic medication. Conventional antipsychotics were administered to 18.9% of residents and atypical antipsychotics to 27.0%. Of the residents, 26.7% were on selective serotonin reuptake inhibitors (SSRIs), 3.1% on tricyclic antidepressants and 17.6% on other antidepressants. Altogether, 44.6% of residents were taking one or more antidepressant. More than a quarter (26.3%) were taking at least one anxiolytic drug. Hypnotics were used by 27.5%. However, only moderate dosages of psychotropic drugs were being taken. Only 10.4% of individuals with dementia were regularly taking cholinesterase inhibitors and four residents were taking memantine.

CONCLUSIONS

Use of psychotropic drugs is very common in nursing homes in Helsinki, Finland, with four of five nursing home residents regularly receiving psychotropic drugs. Only one in ten residents were receiving cholinesterase inhibitors. Physicians caring for nursing home residents require further education on the benefits and adverse effects of psychotropic drugs in frail elderly people.

Concealment of drugs in food and beverages in nursing homes: cross sectional study

OBJECTIVE

To examine the practice of concealing drugs in patients' foodstuff in nursing homes.

DESIGN

Cross sectional study with data collected by structured interview.

SETTING

All five health regions in Norway.

PARTICIPANTS

Professional carers of 1362 patients in 160 regular nursing home units and 564 patients in 90 special care units for people with dementia.

MAIN OUTCOME MEASURES

Frequency of concealment of drugs; who decided to conceal the drugs; how this practice was documented in the patients' records; and what types of drugs were given this way.

RESULTS

11% of the patients in regular nursing home units and 17% of the patients in special care units for people with dementia received drugs mixed in their food or beverages at least once during seven days. In 95% of cases, drugs were routinely mixed in the food or beverages. The practice was documented in patients' records in 40% (96/241) of cases. The covert administration of drugs was more often documented when the physician took the decision to hide the drugs in the patient's foodstuff (57%; 27/47) than when the person who made the decision was unknown or not recorded (23%; 7/30). Patients who got drugs covertly more often received antiepileptics, antipsychotics, and anxiolytics compared with patients who were given their drugs openly.

CONCLUSIONS

The covert administration of drugs is common in Norwegian nursing homes. Routines for such practice are arbitrary, and the practice is poorly documented in the patients' records.

Effect of antipsychotic withdrawal on behavior and sleep/wake activity in nursing home residents with dementia: a randomized, placebo-controlled, double-blinded study. The Bergen District Nursing Home Study

OBJECTIVES

To explore the effect on sleep/wake activity and on behavioral and psychological symptoms of the withdrawal of antipsychotic medications from nursing home (NH) patients with dementia.

DESIGN

Randomized, placebo-controlled, double-blind trial.

SETTING

NHs in Bergen, Norway.

PARTICIPANTS

Thirty patients (mean age 83.5) taking haloperidol, risperidone, or olanzapine for nonpsychotic symptoms.

INTERVENTION

Study participants were randomly assigned to withdrawal (intervention group) or continued treatment with antipsychotic medications (reference group) for 4 consecutive weeks.

MEASUREMENTS

Behavioral rating using the Neuropsychiatric Inventory Questionnaire (NPI-Q) and actigraphy.

RESULTS

After antipsychotic withdrawal, behavioral scores remained stable or improved in 11 of 15 patients, whereas four had worsening scores. Actigraphy revealed decreased sleep efficiency after drug discontinuation and increased 24-hour and night activity in both groups. Actigraphy records of nighttime and daytime activity indicated sleep problems and restlessness, in terms of the NPI-Q. One patient was restarted on antipsychotics.

CONCLUSION

Antipsychotic drug withdrawal affected activity and sleep efficiency over the short term. Increases in total activity and impaired sleep quality after drug discontinuation should be monitored, because the long-term effect of these changes is not known. The NPI-Q and actigraphy are feasible tools that disclose relevant changes occurring during antipsychotic withdrawal in NH patients with dementia. Their use in clinical practice should be substantiated by larger studies.

Which organizational characteristics are associated with increased management of depression using antidepressants in US nursing homes?

BACKGROUND

There is universal agreement that organizational characteristics of nursing facilities can and do influence the quality of care and resident outcomes.

OBJECTIVE

This study evaluated the relation between organizational characteristics and management of depression using antidepressants.

RESEARCH DESIGN

This was a cross-sectional study of Medicare/Medicaid certified nursing homes in 6 states in 2000.

SUBJECTS

We studied 87,907 residents with depression in 2,128 facilities.

MEASURES

Minimum Data Set (MDS) provided information regarding use of antidepressants and resident factors. On-line Survey and Certification of Automated Records (OSCAR) provided facility characteristics information including structural, resource, and staffing levels. Adjusted estimates of organizational effects on antidepressant drug use were derived from generalized estimating equations.

RESULTS

Increased treatment of depression with antidepressants was associated with facilities with a higher percentage of residents from payer sources other than Medicare/Medicaid (odds ratio [OR], 1.04; 95% confidence interval [CI], 1.02-1.06) and more professional nursing staff (OR, 1.15; 95% CI, 1.05-1.26). Decreased treatment tended to be related to larger homes (OR, 0.76; 95% CI, 0.68-0.84) or if the home employed full-time physicians (OR, 0.87; 95% CI, 0.78-0.96). Once the decision to treat was made, treatment with tricyclics tended to be inversely related to larger homes, for-profit facilities, and homes with more Medicare residents.

CONCLUSIONS

Facilities that are required to be more fiscally conservative, be it larger facilities with fewer private pay patients or for profit facilities, have lower rates of pharmacologic treatment. Resource and structural characteristics influence the type of antidepressant being prescribed; resident characteristics may not be the over-riding factor in prescribing.

Not less but different: psychotropic drug utilization trends in Norwegian nursing homes during a 12-year period. The Bergen District Nursing Home (BEDNURS) Study

BACKGROUND AND AIMS

The use of psychotropic drugs in nursing homes is generally considered to be inappropriately high. The aim of the present survey was to compare psychotropic drug use in nursing homes (NHs) in 1985 relative to 1996/97, and to explore predictors for this drug use.

METHODS

Cross-sectional study. Mental capacity was assessed by means of the Clinical Dementia Rating scale (CDR), and behavior registered by trained nurses. Scheduled, daily use of psychotropic drugs among long-term care residents in 1985 (N=1247) and 1996/97 (N=1035) was recorded. Bivariate analyses and logistic regression analyses were applied to establish predictors for psychoactive drug use.

RESULTS

From 1985 to 1996/97, the proportion of residents using any psychotropic drug increased from 52 to 57%. Antipsychotic drug use decreased from 33 to 22%, while anxiolytics increased from 11 to 16%, hypnotics from 11 to 14%, and antidepressants from 12 to 31%. Psychotropic drug use was predominantly associated with behavioral symptoms and not with mental impairment. Concurrent use of two or more psychotropic drugs increased from 23 to 32% of all psychotropic users.

CONCLUSIONS

During the study period, a substantial decline in the use of antipsychotics was observed, but a generally increased overall use of psychotropic drugs, particularly antidepressants. Psychotropic drug treatment was mainly associated with behavioral symptoms.

Factors influencing prescription of CNS medications in different elderly populations

Factors influencing the use of neuroleptic and other CNS-acting medications ('antidepressants' and 'hypnotics/anxiolytics') were examined in different elderly populations (> 65 years): long-stay care hospital subjects (n = 381), nursing home subjects (n = 1247), private residential home subjects (n = 321), statutory residential home subjects (n = 525), old age psychiatry facility subjects (n = 48), community dwellers (n = 97), in different geographical areas (urban n = 1223 and rural n = 1396). Neuroleptics were prescribed in 28% of the individuals, hypnotics/anxiolytics in 33% and antidepressants in 12%. Prescription of neuroleptics was significantly predicted by institutional placement (other than long-stay care hospital facility), lower cognitive function and rural geographical area. Age greater than 75 years and lower functional score (lower dependency) significantly decreased the likelihood of receipt of neuroleptics. Antidepressant use was significantly less likely in male subjects, patients with cognitive impairment and patients greater than 85 years. Institutional placement (other than long-stay care hospital facility and old age psychiatry facility) and rural locality predicted increased likelihood of antidepressant prescription. Institutional placement (other than long-stay care hospital facility) and geographical (rural) location were significant independent predictors of hypnotic/anxiolytic use. Prescription of hypnotic/anxiolytic drug class was significantly less likely in those individuals with lower cognitive status. In this representative elderly cohort, patient characteristics: age, sex, cognitive score, functional score, place of residence and geographical location markedly influenced drug utilisation.

Multidisciplinary medication review in nursing home residents: what are the most significant drug-related problems? The Bergen District Nursing Home (BEDNURS) study

AIM

Based on a multidisciplinary review of drug use in nursing home residents, this study aimed to identify the most frequent clinically relevant medication problems and to analyse them according to the drugs involved and types of problems.

METHODS

Cross sectional study auditing drug use by 1354 residents in 23 nursing homes in Bergen, Norway. Data were collected in 1997. A physician/pharmacist panel performed a comprehensive medication review with regard to indications for drug use and active medical conditions. The drug related problems were subsequently classified according to the drugs involved and types of problems (indication, effectiveness, and safety issues).

RESULTS

2445 potential medication problems were identified in 1036 (76%) residents. Psychoactive drugs accounted for 38% of all problems; antipsychotics were the class most often involved. Multiple psychoactive drug use was considered particularly problematic. Potential medication problems were most frequently classified as risk of adverse drug reactions (26%), inappropriate drug choice for indication (20%), and underuse of beneficial treatment (13%).

CONCLUSIONS

Three of four nursing home residents had clinically relevant medication problems, most of which were accounted for by psychoactive drugs. The most frequent concerns were related to adverse drug reactions, drug choice, and probable undertreatment.
