Prevalencia de síntomas neuropsiquiátricos en pacientes institucionalizados con diagnóstico de demencia y factores asociados: estudio transversal multicéntrico

Objective

The aim was to estimate the prevalence and severity of neuropsychiatric symptoms in patients with dementia in nursing homes, assessing their association with certain factors that may influence their occurrence.

Material and methods

A cross-sectional study was carried out, and included all elderly patients diagnosed with degenerative, vascular, or mixed dementia, stage 4 to 7 on the Global Deterioration Scale of Reisberg (GDS), and residents in 6 nursing homes in the province of Ourense (Spain). A sample size of 120 individuals was determined to be necessary. The assessment of symptoms was performed using the Neuropsychiatric Inventory-Nursing Home test. The influence of the determined factors was investigated using logistic and linear regression analysis, and subsequently corrected for possible confounding factors.

Results

A total of 212 cases were included, with a mean age of 85.7 (SD = 6.7) years. The prevalence of neuropsychiatric symptoms was 84.4%. The most common symptom was apathy, followed by agitation and delirium, and the least frequent were euphoria and hallucinations. The symptom that produced most occupational disruption was agitation. Multivariate analysis showed that a higher score on the NPI-NH was associated with a higher score on the Global Deterioration Scale of Reisberg, the use of neuroleptics, cholinesterase inhibitors, and memantine.

Conclusions

In nursing home patients, prevalence of neuropsychiatric symptoms was high, and associated with the severity of dementia (GDS), the use of neuroleptics, cholinesterase inhibitors, and memantine.     

Cognitive and behavioural impairment among elderly people in institutions providing different levels of care.

OBJECTIVE: To compare the prevalence and degree of cognitive and behavioural impairment in elderly patients in institutions providing different levels of care. DESIGN: Prevalence study. SETTING: A nursing home, a home for the aged and psychogeriatric wards in a provincial psychiatric hospital. PATIENTS: Only subjects 65 years of age or older were eligible for inclusion. A random sample was selected comprising 25% of the residents in the nursing home and the home for the aged; of the 119 asked to participate 95 agreed (44 in the nursing home and 51 in the home for the aged). All 50 on the psychogeriatric wards agreed to participate. MAIN OUTCOME MEASURES: The Mini-Mental State Examination (MMSE) and the Kingston Dementia Rating Scale (KDRS). RESULTS: An MMSE score of less than 24 (cognitive impairment) was given to 37 (84%) of the residents in the nursing home, 43 (84%) of those in the home for the aged and 48 (96%) of the patients in the psychiatric hospital; the corresponding numbers for a KDRS score of more than 0 (cognitive impairment) were 41 (93%), 48 (94%) and 50 (100%). The seven patients receiving the highest level of care at the home for the aged (special care) had more behavioural problems than those in the psychiatric hospital did (p less than 0.001). CONCLUSIONS: Cognitive and behavioural impairment was widespread in the three institutions regardless of the level of care. When planning services and allocating resources government funding agencies should consider the degree and prevalence of such impairment among elderly people in institutions.     

Patients with Korsakoff's syndrome in a nursing home: characteristics and comorbidity

This article presents characteristics and co-morbidity of patients with Korsakoff's syndrome after admission to a nursing home. The medical charts were studied of all patients with Korsakoff's syndrome, admitted between 1984 and 1998 to the special ward for Korsakoff patients of a nursing home in the eastern part of the Netherlands. The 'Standard of classification for diseases in nursing homes' ('Standaard van classificatie voor ziekten in de verpleeghuisgeneeskunde') was used to classify co-morbidity. The group included 77 patients. Almost 75% were male. The average age was 53 years on admission. More than 50% of the patients were divorced. After admission, 30% of the group was transferred to a different setting. The estimated average follow-up period was 7.1 year. Patients had 2.9 co-morbid conditions at admission. Diseases due to alcoholism were frequently diagnosed. During the stay skin diseases, psychological disorders and behavioural disorders were frequently noticed. The prevalence of cognitive impairment and alcohol dementia was surprisingly high. Thirteen patients died, most of them of cancer or combined cardiovascular and respiratory diseases. We conclude that patients with Korsakoff's syndrome are an unexplored area in nursing homes. This group of nursing home inhabitants shows its own characteristics and co-morbidity.     

Onthand Ouderenbeleid. Kanttekeningen bij regeringsplannen 2007

In 1993 Ribbe en Hertogh published a paper in which they expressed their concern about the high prevalence of psychotropic drug use in Dutch nursing homes. Since then, this situation does not seem to have been changed significantly. Recent figures from psychotropic drug use in patients with dementia show prevalence rates of over 60%. The Dutch government decided to choose the prevalence of psychotropic drug use as an indicator of the quality of care and invested in a specific improvement project that aims to reduce psychotropic drug use among nursing home patients. There is a small body of evidence from international research that antipsychotics safely can be reduced without a rise in problem behaviours. In combination with the limited effectiveness and the risk of stroke and increased mortality, the question raises whether these agents should be prescribed at all at least for patients with dementia. A recent study from the UK however, found a significant decrease of antipsychotic drug use by heavily investing in all kinds of person-centered care skills of the nursing staff. These findings underscore the necessity of investing in the caregivers of nursing homes to be able to cope with the complex problems they are faced with.

Do neuroleptic drugs hasten cognitive decline in dementia? Prospective study with necropsy follow up.

OBJECTIVE: To investigate the contribution of neuroleptic drugs to cognitive decline in dementia. DESIGN: Two year prospective, longitudinal study consisting of interviews every four months, with necropsy follow up. SETTING: Community settings in Oxfordshire. SUBJECTS: 71 subjects with dementia, initially living at home with informant. MAIN OUTCOME MEASURES: Cognitive function (score from expanded minimental state examination); behavioural problems (physical aggression, hallucinations, persecutory ideas, and disturbance of diurnal rhythm); and postmortem neuropathological assessment (cortical Lewy body pathology). RESULTS: The mean (SE) decline in cognitive score in the 16 patients who took neuroleptics was twice that in the patients who did not (20.7 (2.9) v 9.3 (1.3), P = 0.002). An increased rate of decline was also associated with aggression, disturbed diurnal rhythm, and persecutory ideas. However, only use of neuroleptics and severity of persecutory ideas were independently associated with more rapid cognitive decline when all other variables were adjusted for. The start of neuroleptic treatment coincided with more rapid cognitive decline: median rate of decline was 5 (interquartile range 8.5) points per year before treatment and 11 (12) points per year after treatment (P = 0.02). Cortical Lewy body pathology did not account for association between neuroleptic use and more rapid decline. CONCLUSIONS: Neuroleptic drugs that are sometimes used to treat behavioural complications of dementia may worsen already poor cognitive function. Randomised controlled trials are needed to confirm a causal relation.     

Anxiety disorders in nursing homes: a literature review of prevalence, course and risk indicators

Psychiatric disorders such as dementia and depression are highly prevalent in nursing homes. The prevalence of anxiety disorders is less clear. Prevalence, course and risk-indicators of anxiety disorders among nursing home residents were examined, based on a review of the literature. Medline and PsychINFO searches were conducted for 1966-2002. Twelve studies were considered relevant. These differed substantially with respect to study-population, diagnostic instruments and diagnostic criteria that were used and the specific anxiety disorders investigated. The prevalence of anxiety disorders ranged from 0-20%. Only in one study the course of anxiety disorders was investigated. About 60% of the nursing home residents recovered in one year. The most important risk-indicators for anxiety disorders identified were: female sex, depression, lack of social support, poor physical health and functional and cognitive impairments. Generalization of these results to the Dutch nursing home population is restricted by the substantial heterogeneity of the studies. Further studies are required to provide reliable estimates of prevalence, course and risk-indicators of anxiety disorders among nursing home residents using appropriate diagnostic instruments and adjusted diagnostic criteria. This will enhance detection and improve treatment of anxiety disorders among nursing home residents.     

Change in Care Dependency and Nursing Care Problems in Nursing Home Residents with and without Dementia: A 2-Year Panel Study

Over time, chronic conditions like dementia can lead to care dependency and nursing care problems, often necessitating nursing home admission. This panel study (2012–2014) aims to explore changes in care dependency and nursing care problems (incontinence, malnutrition, decubitus, falls and restraints) in residents with and without dementia over time. In total, nine Austrian nursing homes participated, including 258 residents (178 with, 80 without dementia) who completed all five measurements. Data were collected with the International Prevalence Measurement of Care Problems questionnaire, the Care Dependency Scale and the Mini-Mental State Examination-2. Repeated measures ANOVA and crosstabs were used to analyse changes. The results showed that care dependency in dementia residents increased significantly for all 15 items of the Care Dependency Scale, with the highest increase being residents’ day-/night pattern, contact with others, sense of rules/values and communication. In contrast, care dependency in residents without dementia increased for four of the 15 items, with the highest increase being for continence, followed by getting (un)dressed. With respect to the assessed nursing care problems, residents with dementia and those without only differed significantly in terms of an increase in urinary- (12.3% vs. 14.2%), fecal- (17.4% vs. 10%), and double incontinence (16.7% vs. 11.9%). The results indicated that residents with dementia experienced increased care dependency in different areas than residents without dementia. Furthermore, residents with dementia experienced a lower increase in urinary incontinence but a higher increase in fecal- and double incontinence. These results help professionals to identify areas for improvement in dementia care.     

The final phase of dementia in a group of nursing home patients: prevalence and characteristics

There is scant literature about patients in the final phase of dementia. Uniform terminology and operational definition of the final phase of dementia is lacking. Furthermore, it is difficult to monitor these patients because existing assessment scales face bottom- or ceiling effects in this population. The aim of this study was to assess the prevalence and the characteristics of patients in the final phase of dementia in a group of 210 Dutch nursing home patients with dementia. Stage 7 of the Global Deterioration Scale of Reisberg et al. was used to operationally define the final phase of dementia. All patients were scored on a self-constructed assessment scale. Furthermore, treatment aspects and advance directives were registered.     

Prevalence of xerostomia and hyposalivation in the nursing home and the relation with number of prescribed medication

In nursing homes, the number of patients with their own dentition increases. Many of them, however, are unable to perform oral hygiene procedures. Medication is considered to be an important cause of hyposalivation, which may lead to oral alterations and loss of teeth. The aim of the present study was to investigate the prevalence of xerostomia and hyposalivation in a Dutch nursing home and to examine the possible relation with medication usage. Between January and March 2001, the salivary flow rates were measured in 50 patients residing in a nursing home in Amsterdam. Unstimulated saliva, parafilm-stimulated saliva and citric acid stimulated saliva were determined. Xerostomia was determined by the question "My mouth feels dry" and the medication used was examined. The data were analysed with (M)ANOVA. The average age of the patients was 78.1 +/- 9.7 years. Forty-eight % of the patients had an unstimulated flow rate of less then 0.20 ml/min and 24% had a flow rate even lower than 0.10 ml/min (reference values: 0.25-0.50 ml/min). The flow rate of women was significantly lower than that of men (p < 0.01), even after correction for age, smoking and the number of prescribed medications. Salivary flow rates decreased significantly with age (p < 0.05). The number of prescribed medication was significantly higher in patients over the age of 70 (p < 0.01, n = 42) and also in women (p < 0.01). The prevalence of xerostomia was 52% with no difference between men and women. In nursing homes, the prevalence of hyposalivation and xerostomia is high. The number of xerogenic medications used seems to be an important factor. Women and patients aged over the age of 70 years need special attention with respect to oral health.     

Seroprevalence of Helicobacter pylori and Length of Stay in a Nursing Home

Background. Helicobacter pylori infection appears to be contracted mainly in childhood, and it is associated with disadvantaged socioeconomic conditions, overcrowding, and living in institutions. In this study we determined the seroprevalence of H. pylori among elderly patients (age ≥ 70 years) admitted to a major medical center in Israel, and studied the relationship between seroprevalence of H. pylori and the duration of stay in a nursing home prior to the admission.
Patients and Methods. Whole blood from 182 consecutive patients hospitalized at the Rabin Medical Center was tested for the presence of anti- H. pylori IgG using Helisal Rapid Blood Test kit (Cortecs Diagnostics). Multivariate logistic regression analysis was used to study the relation between H. pylori seropositivity and possible predictive factors such as age, gender and duration of stay in a nursing home.
Results. Of the 182 patients included in the study, 80 (44%) were living in nursing homes (NH) and 102 (56%) were living in their own homes (H) prior to admission. Subjects that stayed in nursing homes for more than 15 months were significantly more likely to be seropositive than subjects with a shorter duration of stay (84% and 63% respectively, p = 0.03). Using a multivariate logistic regression analysis on both the NH group and the whole group, seropositivity was found to be significantly associated with duration of stay in a nursing home (  p = 0.03 and p = 0.01 respectively). Seropositivity was not associated with age in either group.
Conclusions. Living in a nursing home is associated with increased risk for H. pylori infection in the elderly. There is a strong correlation between the duration of stay in a nursing home and the prevalence of H. pylori infection.     

Behavioural differences between individuals and two populations of stickleback (Gasterosteus aculeatus)

Behavioural syndromes are correlations between behaviours in different functional contexts. Behavioural syndromes are attracting the attention of evolutionary biologists because they mean that different behaviours might not be free to evolve independently of one another. In a landmark study, Huntingford (1976) showed that individual stickleback which were bold toward predators were also aggressive toward conspecifics and active in an unfamiliar environment. Here, I revisited the activity-aggression-boldness syndrome in stickleback and tested the hypothesis that correlations between behaviours might act as evolutionary constraints. I measured a suite of behaviours on wild-caught individuals and their offspring from two different populations and calculated heritabilities and genetic correlations between the different behaviours. I found that these behaviours were phenotypically and genetically correlated in one population but not another. On average, boldness and aggression were negatively related to each other across the populations. These results suggest that behavioural syndromes don't always act as evolutionary constraints.     

Oral health‐related quality of life in patients receiving home‐care nursing: associations with aspects of dental status and xerostomia

doi:10.1111/j.1741‐2358.2009.00344.x
Oral health‐related quality of life in patients receiving home‐care nursing: associations with aspects of dental status and xerostomia Objective: To explore the differences in oral status, dental attendance and dry mouth problems between patients with long‐term disease with high and low scores on Oral Health Impact Profile 14 (OHIP 14) and how patients cope with oral problems such as xerostomia and a reduced ability to brush their teeth. Background: There has been a lack of studies of oral health and oral health‐related quality of life in the frail elderly within the community services. Materials and methods: A cross‐sectional questionnaire study was conducted with 137 patients receiving home‐care nursing. Structured interviews were conducted by student nurses using OHIP‐14, items from the Xerostomia Inventory and questions concerning dental visit habits, brushing of teeth and data from medical records. Results: Eighty‐three per cent of patients had natural teeth and 60% had only natural teeth. ‘Natural teeth only’ indicated a low score on OHIP‐14. Problems with brushing and items concerning xerostomia indicated a high score on OHIP‐14. Contrasts in the assessments concerning brushing of teeth and xerostomia indicated low priority from the patients themselves and the nursing staff. Conclusion: Community health services should focus upon oral health. Both patients and nurses should assess the need for regular brushing of teeth carried out by home‐care nurses. Assessment and treatment of dry mouth problems should have higher priority.     

Factors Associated with Nursing Home Placement of All Patients Admitted for Inpatient Rehabilitation in Singapore Community Hospitals from 1996 to 2005: A Disease Stratified Analysis

Objectives

To (1) identify social and rehabilitation predictors of nursing home placement, (2) investigate the association between effectiveness and efficiency in rehabilitation and nursing home placement of patients admitted for inpatient rehabilitation from 1996 to 2005 by disease in Singapore.

Design

National data were retrospectively extracted from medical records of community hospital.

Data Sources

There were 12,506 first admissions for rehabilitation in four community hospitals. Of which, 8,594 (90.3%) patients were discharged home and 924 (9.7%) patients were discharged to a nursing home. Other discharge destinations such as sheltered home (n = 37), other community hospital (n = 31), death in community hospital (n = 12), acute hospital (n = 1,182) and discharge against doctor’s advice (n = 24) were excluded.

Outcome Measure

Nursing home placement.

Results

Those who were discharged to nursing home had 33% lower median rehabilitation effectiveness and 29% lower median rehabilitation efficiency compared to those who were discharged to nursing homes. Patients discharged to nursing homes were significantly older (mean age: 77 vs. 73 years), had lower mean Bathel Index scores (40 vs. 48), a longer median length of stay (40 vs. 33 days) and a longer time to rehabilitation (19 vs. 15 days), had a higher proportion without a caregiver (28 vs. 7%), being single (21 vs. 7%) and had dementia (23 vs. 10%). Patients admitted for lower limb amputation or falls had an increased odds of being discharged to a nursing home by 175% (p<0.001) and 65% (p = 0.043) respectively compared to stroke patients.

Conclusions

In our study, the odds of nursing home placement was found to be increased in Chinese, males, single or widowed or separated/divorced, patients in high subsidy wards for hospital care, patients with dementia, without caregivers, lower functional scores at admission, lower rehabilitation effectiveness or efficiency at discharge and primary diagnosis groups such as fractures, lower limb amputation and falls in comparison to strokes.     

Cognition problems during rehabilitation of stroke patients in a nursing home

In many regions in the Netherlands the care for stroke patients is organised in a coordinated stroke service. Within these stroke services, each year more patients are referred to nursing homes for a period of rehabilitation. A stroke leads to lasting cognitive and emotional consequences in more than half of the stroke patients. These consequences interfere with the daily life of the patients and their caregivers. Due to the nature and severity of these problems specific care is needed in the nursing home. In the present article a procedure for cognitive screening in a nursing home is described and data of a large group of patients are presented. These data clearly show the magnitude of the cognitive problems: high percentages of impairments are found in many cognitive domains. In the discussion therefore arguments are given for specialised care - assessment as well as treatment - in the nursing home for stroke patients with cognitive deficits.     

Changes in behavioural characteristics of elderly populations of local authority homes and long-stay hospital wards, 1976-7.

Behavioural characteristics of the elderly populations of seven local authority residential homes and three long-stay hospital wards were assessed in 1976 and 1977 with the Crichton Royal behavioural rating scale. In 1977 the levels of behavioural problems had increased in the residential homes, but declined in the hospital wards. Differences between the homes had decreased as the overall level of problems increased. The findings suggested that the additional burden of caring for increasing numbers of severely disabled elderly people was affecting the balance of institutional care, and a radical reappraisal of present patterns of care may be necessary to meet their future needs.     

Palliatieve zorg bij dementie en de ontmanteling van de behandelfunctie van het verpleeghuis

Palliative care in dementia and the dismantlement of nursing home medicinePalliative care is mostly restricted to the terminal phase of incurable illness. According to the WHO revised definition palliative care is specifically directed towards patients and families facing life-threatening illness. This definition is not adequate to orient and direct palliative care policies in non-cancer diseases such as dementia. Although dementia is incurable from the outset, its course is often protracted, resulting in a terminal stage only after several years. This disease trajectory necessitates an alternative palliative approach, implying a proactive attitude of nursing home physicians in facilitating early and timely discussions with patients and their proxies on advance care planning and treatment of complications and concomitant diseases. This, together with their specific training in the treatment of the long term sequelae of chronic diseases, defines the success of Dutch nursing home medicine in foregoing inappropriate hospital admissions and providing adequate medical care in the nursing home. However, recent reorganisations of nursing home care and its funding threaten to downgrade the quality of medical care for patients with dementia in Dutch nursing homes by focusing unilaterally on welfare ideology and ‘marketization’ of long term care, thus underestimating the importance of a palliative care policy in dementia.
