Neuropsychiatric symptoms in patients with dementia in primary care: a study protocol

BACKGROUND: Neuropsychiatric symptoms (NPS) frequently occur in patients with dementia. To date, prospective studies on the course of NPS have been conducted in patients with dementia in clinical centers or psychiatric services. The primary goal of this study is to investigate the course of NPS in patients with dementia and caregiver distress in primary care. We also aim to detect determinants of both the course of NPS in patients with dementia and informal caregiver distress in primary care. METHODS/DESIGN: This is a prospective observational study on the course of NPS in patients with dementia in primary care. Thirty-seven general practitioners (GPs) in 18 general practices were selected based on their interest in participating in this study. We will retrieve electronic medical files of patients with dementia from these general practices. Patients and caregivers will be followed for 18 months during the period January 2012 to December 2013. Patient characteristics will be collected at baseline. Time to death or institutionalization will be measured. Co-morbidity will be assessed using the Charlson index. Psychotropic drug use and primary and secondary outcome measures will be measured at 3 assessments, baseline, 9 and 18 months. The primary outcome measures are the Neuropsychiatric Inventory score for patients with dementia and the Sense of Competence score for informal caregivers. In addition to descriptive analyses frequency parameters will be computed. Univariate analysis will be performed to identify determinants of the course of NPS and informal caregiver distress. All determinants will then be tested in a multivariate regression analysis to determine their unique contribution to the course of NPS and caregiver distress. DISCUSSION: The results of this study will provide data on the course of NPS, which is clinically important for prognosis. The data will help GPs and other professionals in planning follow-up visits and in the timing for offering psycho-education, psychosocial interventions and the provision of care. In addition, these data will enlarge health professionals’ awareness of NPS in their patients with dementia

Is the approach of delirium in dutch nursing-homes in accordance with the national guideline?

Introduction: Delirium is a common disorder, affecting many patients in nursing-homes, with large impact on patients. Implementation of good care and treatment can potentially prevent development of a delirium or may reduce the severity or duration. This research was conducted to get an impression of delirium care in Dutch nursing homes, and of the implementation of the recommendations of the national guideline. Objectives: 1. How many Dutch nursing homes have a local protocol for delirium? 2. To what extend do doctors, specialised in care for older people in nursing homes, screen, diagnose and treat delirium according to the Dutch guideline for delirium? Methods: Between June and December 2016, Dutch nursing homes were approached with an online questionnaire. Data were collected in Survey Monkey and descriptive analyses were performed. Results: 68 nursing homes were included. 32% of the nursing homes had a local delirium protocol. 48% of the doctors knew about the national guideline delirium, 60% used preventive measures, and screening instruments were used in 98%. 29% used diagnostic criteria. Non-medical interventions were applied by 96%. In 98%, haloperidol was the drug of first choice. Preventive antipsychotics were prescribed by 21%. Conclusions: Only a third of the organisations developed a local delirium protocol. Standardising delirium care by a local delirium protocol, with special attention for prevention, diagnostics and aftercare of delirium, can be an important step in improving the quality of care in nursing homes.</p

Improving psychotropic drug prescription in nursing home patients with dementia:design of a cluster randomized controlled trial

Background: Neuropsychiatric symptoms are highly prevalent in nursing home patients with dementia. Despite modest effectiveness and considerable side effects, psychotropic drugs are frequently prescribed for these neuropsychiatric symptoms. This raises questions whether psychotropic drugs are appropriately prescribed. The aim of the PROPER (PRescription Optimization of Psychotropic drugs in Elderly nuRsing home patients with dementia) II study is to investigate the efficacy of an intervention for improving the appropriateness of psychotropic drug prescription in nursing home patients with dementia.Methods/design: The PROPER II study is a multi-center cluster randomized controlled, pragmatic trial using parallel groups. It has a duration of eighteen months and four six-monthly assessments. Six nursing homes will participate in the intervention and six will continue care as usual. The nursing homes will be located throughout the Netherlands, each participating with two dementia special care units with an average of fifteen patients per unit, resulting in 360 patients. The intervention consists of a structured and repeated multidisciplinary medication review supported by education and continuous evaluation. It is conducted by pharmacists, physicians, and nurses and consists of three components: 1) preparation and education, 2) conduct, and 3) evaluation/guidance. The primary outcome is the proportion of patients with appropriate psychotropic drug use. Secondary outcomes are the overall frequency of psychotropic drug use, neuropsychiatric symptoms, quality of life, activities of daily living, psychotropic drug side effects and adverse events (including cognition, comorbidity, and mortality). Besides, a process analysis on the intervention will be carried out.Discussion: This study is expected to improve the appropriateness of psychotropic drug prescription for neuropsychiatric symptoms in nursing home patients with dementia by introducing a structured and repeated multidisciplinary medication review supported by education and continuous evaluation.</p

The human keratins: biology and pathology

The keratins are the typical intermediate filament proteins of epithelia, showing an outstanding degree of molecular diversity. Heteropolymeric filaments are formed by pairing of type I and type II molecules. In humans 54 functional keratin genes exist. They are expressed in highly specific patterns related to the epithelial type and stage of cellular differentiation. About half of all keratins—including numerous keratins characterized only recently—are restricted to the various compartments of hair follicles. As part of the epithelial cytoskeleton, keratins are important for the mechanical stability and integrity of epithelial cells and tissues. Moreover, some keratins also have regulatory functions and are involved in intracellular signaling pathways, e.g. protection from stress, wound healing, and apoptosis. Applying the new consensus nomenclature, this article summarizes, for all human keratins, their cell type and tissue distribution and their functional significance in relation to transgenic mouse models and human hereditary keratin diseases. Furthermore, since keratins also exhibit characteristic expression patterns in human tumors, several of them (notably K5, K7, K8/K18, K19, and K20) have great importance in immunohistochemical tumor diagnosis of carcinomas, in particular of unclear metastases and in precise classification and subtyping. Future research might open further fields of clinical application for this remarkable protein family

Gender differences in clusters of NPS in Dutch nursing homes - a factor analysis

Item does not contain fulltextBACKGROUND: Neuropsychiatric symptoms (NPS) have a high prevalence among patients with dementia, up to 80%. NPS can be grouped by type and stage of dementia. However, NPS have not previously been grouped by gender. Our objective was to investigate whether NPS cluster differently in men or women in the nursing home patients. METHODS: Factor analysis to assess the clustering of items in the Cohen-Mansfield Agitation Inventory (CMAI) and Neuropsychiatric Inventory-Nursing home version (NPI-NH) into components, for both scales and for gender. Differences in symptom clustering between male and female patients were assessed using a three-step procedure: (1) identifying a gender specific distinctive item, (2) describe the correlation between the distinctive item with any other item in this cluster, (3) testing whether the correlation between a distinctive item and any other item in the cluster (which is present in both sexes) is different for males and females using a general linear model. RESULTS: Our database consisted of 1,609 patients. There were five male and three female clusters for NPI-NH and eight male and seven female clusters for CMAI. There were three distinctive items in the NPI-NH and ten in the CMAI. CONCLUSIONS: There are other clusters of NPS in males and females. Our analysis revealed more significant relations in female than male patients. This might have an implication on the clinical course

The course of neuropsychiatric symptoms in community-dwelling patients with dementia: a systematic review

Background: Neuropsychiatric symptoms (NPS) often occur in patients with dementia. Understanding the course of NPS in dementia is important for healthcare professionals for psycho-educational purposes and adequate and timely interventions to prevent or diminish NPS as much as possible. Methods: We conducted a systematic literature search in several electronic databases. We combined search strings for the terms dementia, community-dwelling, cohort studies and NPS. Screening titles and abstracts, assessing the methodological quality and data-extraction were independently conducted by at least two authors. Results: This literature search revealed 6605 unique records of which 23 studies were included in data synthesis. In total 7184 patients participated in the included studies with a mean number of 312. Sixty percent of the participants were female and the mean age of all participants was 74.8 years. Follow-up varied between 1 and 6 years; in 17 studies loss to follow-up was less than 20% per year. NPS are highly prevalent, incident and persistent although frequency parameters vary considerably across studies. Delusions/delusional misidentification, wandering/agitation, aberrant motor behavior/motor hyperactivity and apathy are the most common NPS. For hallucinations, delusions/delusional misidentification, paranoia, aggression, wandering/agitation, aberrant motor behavior/motor hyperactivity, disinhibition, apathy, and sleep disturbance increasing trends in point prevalence rates have been found. Conclusions: NPS in community-dwelling patients are frequent and persistent. The increasing trends of several NPS in the course of dementia require a preventive approach of professional caretakers. For such an approach, a timely diagnosis and adequate professional support to prevent or diminish these problems is necessary

Neuropsychiatric symptoms and psychotropic drug use in patients with dementia in general practices

Background. Neuropsychiatric symptoms (NPS) frequently occur in community-dwelling patients with dementia and they are also frequently prescribed psychotropic drugs. The prescription of psychotropic drugs has been found to be associated with the level of NPS. Data on NPS in patients with dementia in general practices are scarce. Objectives. The aim of this study was to assess the prevalence rates of NPS and psychotropic drug use (PDU) in patients with dementia in general practices. Methods. We analyzed data from the baseline measurement of a prospective cohort study in a sample of (Dutch) patients in general practices. Prevalence rates of NPS and subsyndromes assessed with the Neuropsychiatric Inventory (NPI) and of PDU were calculated. Prevalence rates of individual NPS are presented both as clinically relevant symptoms (NPI symptom score = 4) and as prevalence rates of symptoms with symptom score > 0. Results. Of the 117 patients, more than 90% had at least one symptom and more than 65% had at least one clinically relevant symptom. The most common NPS were agitation/aggression, dysphoria/ depression and irritability/lability. The most common clinically relevant NPS were aberrant motor behaviour, agitation/aggression and apathy/indifference. Only 28.7% of the patients used at least one, 7.0% used at least two different and 1.7% used at least three different types of psychotropic drugs (excluding anti-dementia medication). Conclusions. NPS are highly prevalent in patients with dementia in general practices, but PDU is rather low. The most common clinically relevant NPS were aberrant motor behaviour, agitation/ aggression and apathy/indifference

Validity of the Severe Impairment Battery Short Version

International audienceEfficient neuropsychological tests are needed to measure cognitive impairment in moderate to severe dementia

The course of neuropsychiatric symptoms in patients with dementia in primary care

BACKGROUND: During the course of dementia, most people develop some type of neuropsychiatric symptoms (NPS), which result in lower quality of life, high caregiver burden, psychotropic drug use and a major risk of institutionalization. Studies on NPS in people with dementia have been mainly conducted in clinical centres or psychiatric services. OBJECTIVES: To investigate the course of NPS in people with dementia in primary care. METHODS: Analysis of (cumulative) prevalence and incidence, persistence and resolution based on data collected during an assessment at home of a prospective naturalistic cohort study in primary care in a sample of 117 people with dementia and their informal caregivers. Subsyndromes of NPS were assessed with the Neuropsychiatric Inventory (NPI) and Cohen-Mansfield Agitation Inventory. Multivariate analyses were used to detect determinants for the course of NPS. RESULTS: The mean age of the people with dementia was 78.6 years, and 52% were female. Mean Mini-Mental State Examination total score was 19.5, mean NPI total score 15.7. The most prevalent clinically relevant subsyndromes of the NPI were hyperactivity and mood/apathy, and the most prevalent individual NPS were aberrant motor behaviour (28%), agitation/aggression (24%) and apathy/indifference (22%). Of the people with dementia, 72.3% had one or more symptoms of the mood/apathy and 75.3% of the hyperactivity subsyndrome. CONCLUSIONS: GPs should be aware of NPS in people with dementia and should actively identify them when they visit these patients or when informal caregivers consult them. Timely diagnosing facilitates adequate professional care
