Assessment of dementia in nursing home residents by nurses and assistants: criteria validity and determinants.

OBJECTIVES: To describe the criterion validity of nursing home staff's assessment of organic disorder compared with ICD-10 criteria, and to identify determinants of staff assessment of organic disorder. METHOD: Two hundred and eighty-eight residents were diagnosed using the GMS-AGECAT. Nursing staff members were interviewed about the residents' activities of Daily Living, behavioural problems, orientation in surroundings and communication skills, and asked if the resident had an organic disorder. Multiple logistic regression was used to select the items that most strongly determined staff assessment of organic disorder. RESULTS: Sixty-two per cent of the residents were diagnosed by GMS-AGECAT as having organic disorder, 78% of these were correctly identified by the staff. Whether analysed among residents with or without organic disorder, or in the total group of residents, the staff assessment of the presence of organic disorder depended on a limited set of behavioural characteristics of the resident, namely 'going to the toilet in inappropriate places', 'saying things that do not make sense' and impairment in orientation. CONCLUSIONS: Staff comprehension of organic disorder resulted in over- as well as under-labelling of residents, a tendency that will affect communication with medical personnel and may lead to inadequate or wrong medical treatment and to negative performance as well as negative role expectations in everyday life in nursing homes.

Determinants for the use of psychotropics among nursing home residents.

PURPOSE: To characterise the prescription pattern of psychotropics in Danish nursing homes and to identify diagnostic, behavioural, cognitive and performance characteristics associated with prevalent psychotropic drug use. METHODS: Prescribed daily medication was recorded from nurses' files. Based on the Anatomical Therapeutical Chemical (ATC) classification index, psychotropics were categorised into neuroleptics, benzodiazepines and antidepressants. Two hundred and eighty-eight residents were diagnosed using the GMS-AGECAT. One hundred and eighteen staff members were interviewed about the residents's Activities of Daily Living (ADL), behavioural problems (Nursing Home Behavior Problem Scale), orientation, communication skills and if the resident had any psychiatric disorder. Multiple logistic regression was used to select the items that determined the use of psychotropics. RESULTS: Fifty-six percent of the residents received a psychotropic, 21% received neuroleptics, 38% received benzodiazepines and 24% received antidepressants. In the multivariate analysis, staff assessment of the resident's mental health was a determinant for the use of all types of specific psychotropics, whereas a GMS-AGECAT diagnosis only determined the use of neuroleptics. Behavioural problems were a determinant for the use of neuroleptics and the use of benzodiazepines irrespective of the psychiatric diagnosis of the resident. Use of antidepressants was associated with male gender and increasing age. CONCLUSIONS: Staff perceptions of psychiatric morbidity and norms have a greater impact on the prescription of psychotropics than standardised clinical criteria.

Empirical weighting of the Standardized Mini Mental State Examination items among nursing home residents.

Missing items in the Mini Mental State examination are dealt with in different ways. The main aims of this study were to calculate a weighted item score for organic disorder on the basis of the item score of the Standardized Mini Mental State Examination (SMMSE) test regardless of the completeness of the test and to compare the criterion validity of the weighted scores with the ordinal scores for the SMMSE test. With a participation of 91%, the study included 100 nursing residents. All residents were tested with the SMMSE test and concurrently diagnosed in accordance with the ICD-10 by a consultant psychiatrist. The two assessments were mutually blinded. Multiple conditional forward logistic regression was used to select the items that most strongly predicted organic disorder as assessed by the psychiatrist. The weighted score had significantly better validity parameters, performed better on a receiver operating curve (ROC), and was better at dichotomizing the population into organic disorder than the commonly used ordinal score. We propose that missing items in the SMMSE should be scored as missing and included in empirical weighting on SMMSE items, which will then be substantially more valid than the SMMSE score itself.

[Prevalence of depressive disorders among frail elderly, assessed by psychogeriatricians, general practitioners and geriatricians]. / Praevalens af depressionssygdom blandt svage aeldre, vurderet ved gerontopsykiater, praktiserende laeger og geriater.

UNLABELLED: The prevalence of depressive disorders (D) in 70 years of age or older frail elderly was studied. Two hundred and eleven (81%) recipients of Municipal Home Help Service (frail elderly) in a rural area of Jutland were included and screened by the Geriatric Depression Scale-15 (GDS). If participants had: a) a GDS-score > or = 5 points or/and b) a history of depression, further evaluation was given by: 1) general practitioners (GPs) (implicit criteria), 2) a psycho-geriatrician (ICD-10 criteria), and 3) a geriatrician with the Hamilton Test for Depression. Prevalence rates for D among the evaluators: 15-18%. The diagnostic agreement was only fair. IN CONCLUSION: 18% of the studied population fulfilled the ICD-10 research criteria for depression. The GDS may help GPs in diagnosing depression among frail elderly. False GDS negatives, found among GDS negatives with a history of depression, should be evaluated thoroughly when identifying depression in the target group.

[Nursing home residents in Northern Jutland]. / Plejehjemsbeboere i Nordjylland.

The purpose of the study was to describe a Danish nursing home population. The study consists of 288 nursing home residents (median age 84.6 years, 68% females). The psychiatric morbidity of the residents was diagnosed with the GMS-AGECAT. The staff was interviewed about the residents' ADL, disturbing behaviour and therapeutic measures. Seventy-one percent had a psychiatric disorder, with organic disorder as the most frequent (61%). Demented residents received significantly less hypnotics, were more often physically restrained and had lower ADL levels compared to other residents. The situation in Denmark can be seen as a paradox. While substantial effort has been made to increase the possibility of choice and to "deinstitutionalize" nursing homes, the majority of the residents are demented and thus not capable of making valid choices.

[Treatment of delirium in a psychogeriatric university hospital department. Etiology, treatment concept and outcome]. / Behandling af delirium på en gerontopsykiatrisk universitetsafdeling. Aetiologi, behandlingskoncept og behandlingsresultater.

The purposes of the study were to account for aetiology, treatment concept, outcome of treatment, and discharge destination of delirious elderly inpatients. During one year all patients in a psychogeriatric university department were assessed on admission and at discharge with a selection of assessments measuring psychopathology, behavioural disorders, depressive symptoms, intellectual functioning, activities of daily living, and gait. Diagnoses were made according to the ICD-10 criteria for research. All patients with a principal diagnosis of delirium (n = 26) are accounted for. Delirious patients improved their health status significantly in all the assessments, and 86% of patients admitted from independent living were discharged to independent living. It is concluded that elderly inpatients with severe or prolonged delirium profit significantly from the treatment concept in all of the rated health aspects.

[A symptom profile of hospitalization-requiring depression among the elderly related to clinical subgroups. A way to improve diagnostics]. / Symptomprofil ved indlaeggelseskraevende depression hos aeldre, relateret til kliniske undergrupper. En genvej til forbedret diagnostik.

UNLABELLED: The objectives were to study clinical symptoms of major depression in later life by using relevant assessment scales of psychopathology, behavioural disorders, and physical functioning. The evaluations on admission and at discharge were based on interdisciplinary observations and interview of patients. The study was carried out during twelve months in a psychogeriatric university department and encompassed 202 patients. All (N = 80) (40%) patients who had a principal diagnosis of major depression are accounted for. Mean age was 79.5 years. Results of the assessments all showed significant improvements (p = 0.0000-0.0024). The overall results of the assessments show that the key symptom of sadness is often missing, muted, or overshadowed by other symptoms, and that behavioural disturbancies and functional disability may be important symptoms in geriatric depression. IN CONCLUSION: adequate treatment of major depression in the elderly significantly improves psychopathology, behavioural disorders and physical functioning. When dealing with mental disorders in this age group, awareness of the five clinical presentations in major geriatric depression, i.e. dementoform, somatoform neurotiform, eretic and classic geriatric depression, may target the diagnostic procedure.

Concurrent validity of the GMS-AGECAT (A3) package in a Danish nursing home population.

AIM: To validate the Danish version of the GMS-AGECAT (A3), the Standardized Mini Mental State Examination (SMMSE) and the Geriatric Depression Scale-15 (GDS-15) by comparing them to clinical ICD-10 criteria in a Danish nursing home population. METHODS: With a participation of 91%, the study included 100 residents. All residents were interviewed with the GMS-AGECAT (A3), SMMSE and GDS-15 by an MD and then blindly diagnosed by a consultant geriatric psychiatrist. All residents approached for an interview were included, also those who were not able to communicate (the non-accessibles). RESULTS: The prevalence of clinical psychiatric ICD-10 main diagnoses was 56%. The non-accessibles had significantly higher psychiatric morbidity and lower ADL scores (modified Barthel ADL index) compared to those who were able to communicate. With the non-accessibles (N = 100) included, the optimal screening and diagnostic cutpoint for the GMS-AGECAT organic diagnoses was 2/3, with 96% sensitivity, 73% specificity, 77% predictive value of a positive test and 95% predictive value of a negative test. The SMMSE and GDS-15 had better screening properties compared to the GMS-AGECAT but only 60% of the residents were able to complete the SMMSE and 78% were able to complete the GDS-15. CONCLUSION: The Danish version of the GMS-AGECAT has relevant diagnostic and screening properties for organic disorders in Danish nursing home populations.

Psychopathologic and functional outcome in the treatment of elderly inpatients with depressive disorders, dementia, delirium and psychoses.

The objectives of this report were to investigate the functional implications and the possible rehabilitation potentials of dementia, delirium, and psychosis in elderly inpatients, compared with that in depression. During 1 year, all patients in a psychogeriatric university clinic were assessed on admission and at discharge with a selection of rating scales and diagnosed according to ICD-10 by consultants with no knowledge of the results of the ratings. All patients who had a principal diagnosis of major depression, dementia, delirium, or a psychosis are discussed. Ratings were made for psychopathology, behavioral disorders, depressive statements, intellectual functioning, activities of daily living, and gait. Depressive and delirious patients improved their status significantly (p < or = .03) in all six assessments, and patients with dementia improved their psychopathology status (p = .002), but the other assessments were unchanged. Results from the small sample (n = 8) of psychotic patients were mainly inconclusive, but there was a tendency for improvement with respect to psychopathology and gait.

[A clinic for the study of dementia--110 consecutive patients]. / Klinik for demensudredning--110 konsekutive patienter.

Case reports of 110 patients referred to a neurological dementia clinic were reviewed to evaluate a standardized diagnostic program. The patients were evaluated by a neurologist, a gerontopsychiatrist, and a neuropsychologist. ICD-10 criteria were used. Fifty-two patients had dementia while 58 had not; of these, 27 suffered from other non-dementia diseases and 31 were without dementia or other psychiatric or neurological disease. Thirteen patients with Alzheimer's disease were treated with tacrine. Four patients underwent cobalamin substitution treatment and seven started antidepressant medication. Ten patients received acetylsalicylic acid (150 mg Q.D.) and two a levo-dopa-type drug. Twenty-six patients were followed by gerontopsychiatric district care. Because only 47% of the patients suspected of dementia actually fulfilled dementia criteria, the evaluation suggests that patients suspected of dementia benefit from a standardized diagnostic program in a specialist setting.

[Improvement of functional abilities after treatment of depression in the elderly]. / Funktionsforbedring ved behandling af depression hos aeldre.

During one year all patients with a diagnosis of depression in accordance with ICD-10, referred to a psychogeriatric department, were assessed at admission and discharge with a number of rating scales: The Brief Geriatric Depression Scale, Katz' ADL-index, the Multidimensional Dementia Assessment Scale, the Mini-Mental State Examination and the Functional Ambulation Classification. The department has an active stepwise treatment strategy: SSRI (selective serotonin reuptake inhibitor), potentiation with mianserin, lithium potentiation, ECT. The 87 depressive patients had a median age of 79 and most had one or more severe somatic conditions. Fifty-nine were severely depressed at admission, 19 at discharge; the number of functionally disabled dropped from 22 to seven and the number of cognitively impaired from 35 to 19. In conclusion, a nihilistic approach to treatment in the very old is unfounded.

Serum cobalamin and methylmalonic acid in Alzheimer dementia.

The cobalamin status was evaluated in Alzheimer dementia (n = 26), other dementias (n = 24), various gerontopsychiatric disorders (n = 25), and in neuro-psychiatrically healthy controls (n = 20). Supplementing serum cobalamin we measured methylmalonic acid (MMA), a metabolite accumulating early in cobalamin deficiency. Subnormal cobalamin and/or clearly elevated MMA concentrations were found in 11 cases: 7 Alzheimer patients (27%), 2 with other dementias (8%), one psychiatric patient (4%), and one control (5%). None presented the typical neurologic features of cobalamin deficiency and macrocytosis was found in only one. The mean cobalamin concentration was significantly lower in Alzheimer patients (179 +/- 18 pmol/l) than in the age-matched controls (256 +/- 23 pmol/l) (p = 0.013) and the other patient groups. Correspondingly, the mean MMA level was higher in the Alzheimer group (0.480 +/- 0.062 mumol/l) than in any other diagnostic group (controls: 0.347 +/- 0.040 mumol/l). Comparing the Alzheimer group to the other groups as a whole, the elevation was significant (p = 0.0097). Our findings indicate that Alzheimer patients are particularly prone to cobalamin deficiency, and even subtle biochemical signs of deficiency seem to justify treatment.

[Psychopharmacological treatment of elderly patients with dementia. Recommendations and guidelines]. / Psykofarmakologisk behandling af demente aeldre. Forslag og retningslinier.

Behavioral-disturbed elderly patients with dementia are often treated with psychotropic drugs, frequently by doctors who only have sporadic contact with such cases. Knowledge concerning psychotic symptoms and behavioural disturbances in dementia has increased over the past years, as to a certain extent has the number of investigations of psychopharmacological therapy in demented patients. Based on results of controlled drug trials and empiric consensus among psychogeriatricians, recommendations and guidelines regarding indications for drug therapy and type of psychotropic drug suitable for the treatment of psychiatric problems in dementia are given.

[Inappropriate psychopharmacological treatment of the elderly. A 1-year study]. / Uhensigtsmaessig psykofarmakologisk behandling af aeldre. En årsopgørelse.

The psychogeriatric department in the county of Arhus is in a unique position to collect cases of old people treated with psychotropics in various inappropriate ways in hospital wards or by general practitioners. In 1991 the department was in contact with 768 elderly people mostly on an outpatient basis among whom 40 patients exhibited accumulated errors of psychopharmacologic treatment. The treatment episodes were analysed. The patients were very old (mean 80.8 years) with severe somatic morbidity. A majority were demented or delirious. 75% were living in nursing homes. The treatment episodes exhibited polypharmacy and large doses of neuroleptics (mean 0.7 DDD/day) or benzodiazepines (mean 1.41 DDD/day). Psychotropics not suitable for elderly patients were used in 34 patients. Indications for treatment were mostly unspecified behavioural disturbances, sometimes reflecting inappropriate social support. The majority of patients had side effects, sometimes rendering the patient more acceptable to staff and other residents.

[Dementia and ethics. From psychopharmacologic agents to living wills]. / Demens og etik. Fra psykofarmaka til livstestamente.

Psychotropics are to a great extent used in nursing homes to sedate and incapacitate the residents for social reasons. The very high prescription rate also reflects gerontophobic and dementophobic myths placing the old and disturbing patient beyond general accepted ethical rules. The problem is highlighted by the new Danish law concerning the uncurable ill patient. Under certain conditions it is now legal not to treat demented people for a life threatening but treatable physical illness. The boundaries between active and passive euthanasia seem more and more blurred concerning old demented patients.

[Use of psychopharmaceuticals in municipal nursing homes. A nationwide survey]. / Brug af psykofarmaka på kommunale plejehjem. En landsdoekkende undersøgelse.

In 32 nursing homes selected at random in the 16 counties in Denmark, the use of psychotropic medication was studied in all residents aged over 65 years (1454 persons) by interview of nursing staff and review of treatment records regarding drug group, dose, duration of treatment and target symptoms. Psychotropic prescriptions were recorded in 56% of the elderly. The frequency of residents receiving daily treatment with neuroleptics was 20% and for anxiolytics, hypnotics and antidepressants 13%, 33% and 11%, respectively. The duration of treatment was two to three years. The indications were mostly unspecified behavioural disturbances. The use reflects the high psychiatric morbidity in nursing home residents, especially regarding dementia. From what is known of therapeutic efficacy and side-effects, it is concluded that the prescription rate is too high, duration of treatment much longer than necessary and that drugs inappropriate for elderly are often used.

Dementia in Denmark from a medical view.

The field of psychogeriatrics, including diagnosis and treatment of age-associated dementia, is still in its early years in Denmark. Most of the treatment of the elderly with psychiatric conditions lies in the hands of general practitioners and staff of somatic nursing homes. In a few places in Denmark, a more academic approach to the elderly patients has developed in general psychiatric hospitals. Psychogeriatric department D at The Psychiatric University Hospital in Arhus is an example. Treatment ideology, strategies, education, outpatient treatment and hospital-treatment is described, especially regarding age-associated dementia.

[The admission and discharge patterns of patients with dementia in psychiatric hospitals]. / Demente patienters indlaeggelses- og udskrivningsmønster på psykiatriske hospitaler.

This paper describes the admission and discharge pattern in a psychiatric hospital for 315 senile and arteriosclerotic demented patients (290.09, 293.09 ICD-8) aged 65 years and over and admitted for the first time. 47% (149) of the patients were admitted from other hospitals and temporary stays in nursing homes. A total of 203 (65%) of the patients experienced one or more changes of residence during the three months prior to admission to the psychiatric hospital. A Kaplan-Meier analysis showed that 25% of the patients were still hospitalized 48 weeks after admission. A total of 62 patients died in the psychiatric hospital, one patient was still hospitalized when the investigation ceased. Of those discharged alive 201, (80%) were discharged to nursing homes 26 (10%) to their own homes and 25 (10%) to hospitals. Of those who had their own home at the time of admission and were discharged alive only 16% were discharged to their own homes, the remainder were discharged to nursing homes and hospitals. On account of the many changes of environment the demented patients experience prior to admission to the psychiatric hospital, they risk developing confusional psychoses which may be disastrous to their physical and mental health.

[Use of psychopharmaceuticals and commitment in psychiatric admissions of elderly patients with dementia]. / Brug af psykofarmaka og tvang ved psykiatriske indlaeggelser af aeldre demente.

Case records of 404 elderly patients (aged 65 years or more) who were admitted for the first time to the Psychiatric Hospital in Aarhus were investigated retrospectively. In 315 patients the diagnoses were senile dementia (290.09) and arteriosclerotic dementia (293.09) according to ICD-8. Information about use of psychotropic drugs before admission and on discharge alive was obtained from the patient case records. In the present study, the use of drugs was not found to be correlated with age, sex and degree of dementia. Significantly fewer committed patients were treated with psychoactive drugs and significantly fewer lived independently in their own homes. Only 42 (13%) patients had a crude psychiatric disorder while 251 (80%) were admitted on account of unacceptable behaviour. 90% of the latter group of patients had been treated with one or more psychoactive drugs on admission. The risks involved in the use of psychoactive drugs are discussed. On account of demographic changes in the Danish population and the recent decrease in psychiatric hospital beds and nursing home beds, it is recommended that the patterns of committed admissions of demented patients to psychiatric hospitals should be followed closely.
