Factors Related to Psychotropic Drug Prescription for Neuropsychiatric Symptoms in Nursing Home Residents With Dementia

OBJECTIVES The objective of this study is to explore factors that elucidate reasons for psychotropic drug (PD) prescription for neuropsychiatric symptoms (NPS) in nursing home (NH) residents with dementia. DESIGN A qualitative study using a grounded theory approach. SETTING Twelve NHs in The Netherlands. PARTICIPANTS Fifteen physicians and 14 nurses. MEASUREMENTS Individual, face-to-face, in-depth semistructured interviews. Interviews were audio recorded, transcribed, and qualitatively analyzed using Atlas.ti. RESULTS The qualitative analysis revealed 4 emerging themes with factors either or both enhancing or limiting PD prescription, which we used to develop a conceptual framework. First, the mindset of physicians and nurses toward NPS and PDs appeared to contribute. Second, inadequate knowledge of and experience with NPS and limited people skills of nurses may induce PD prescription. Also, knowledge of effectiveness and side effects of PDs from education, literature, and guidelines, and previous personal experiences was considered relevant. Third, effective communication and cooperation between professionals and with family may improve the appropriateness of PD prescription. Fourth, external factors including staffing issues, nursing home setting, access to consultants, national and local policies, and zeitgeist were considered to affect PD prescription. CONCLUSION We have developed a conceptual framework explaining how different factors influence PD prescription. This provides opportunities for improving PD prescription in NH residents with dementia.

PROPER I: frequency and appropriateness of psychotropic drugs use in nursing home patients and its associations: a study protocol.

BackgroundNursing home patients with dementia use psychotropic drugs longer and more frequently than recommended by guidelines implying psychotropic drugs are not always prescribed appropriately. These drugs can have many side effects and effectiveness is limited. Psychotropic drug use between nursing home units varies and is not solely related to the severity of neuropsychiatric symptoms. There is growing evidence indicating that psychotropic drug use is associated with environmental factors, suggesting that the prescription of psychotropic drugs is not only related to (objective) patient factors. However, other factors related to the patient, elderly care physician, nurse and the physical environment are only partially identified. Using a mixed method of qualitative and quantitative research, this study aims to understand the nature of psychotropic drug use and its underlying factors by identifying: 1) frequency and appropriateness of psychotropic drug use for neuropsychiatric symptoms in nursing home patients with dementia, 2) factors associated with (appropriateness of) psychotropic drug use.MethodsA cross-sectional mixed methods study. For the quantitative study, patients with dementia (n = 540), nursing staff and elderly care physicians of 36 Dementia Special Care Units of 12 nursing homes throughout the Netherlands will be recruited. Six nursing homes with high average rates and six with low average rates of psychotropic drug use, based on a national survey about frequency of psychotropic drug use on units, will be included. Psychotropic drugs include antipsychotics, anxiolytics, hypnotics, antidepressants, anticonvulsants and anti-dementia drugs. Appropriateness will be measured by an instrument based on the Medication Appropriateness Index and current guidelines for treatment of neuropsychiatric symptoms. Factors associated to psychotropic drug use, related to the patient, elderly care physician, nurse and physical environment, will be explored using multilevel regression analyses. For the qualitative study, in depth interviews with staff will be held and analyzed to identify and explore other unknown factors.DiscussionThis study will provide insight into factors that are associated with the frequency and appropriateness of psychotropic drug use for neuropsychiatric symptoms. Understanding psychotropic drug use and its associations may contribute to better dementia care.

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

BackgroundNeuropsychiatric 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/designThe 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.DiscussionThis 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.Trial registrationNetherlands Trial Registry (NTR): NTR3569.

The effect of biannual medication reviews on the appropriateness of psychotropic drug use for neuropsychiatric symptoms in patients with dementia: a randomised controlled trial

Objective We studied the efficacy of biannual structured medication reviews to improve the appropriateness of psychotropic drug (PD) prescriptions for neuropsychiatric symptoms (NPS) in nursing home patients with dementia. Study Design and Setting In this randomised controlled trial, the intervention encompassed a structured multidisciplinary medication review by physician, pharmacist and nurse. During this 18-month study, the patients medical files were assessed every 6 months. The primary outcome was the appropriateness of PD prescriptions defined by the Appropriate Psychotropic drug use In Dementia (APID) index sum score, lower scores indicating more appropriate use. Results At baseline, 380 patients were included, of which 222 were randomised to the intervention group. Compared to the control group, the APID index sum score in the intervention group improved significantly for all PD prescriptions (-5.28, P = 0.005). Conclusion We advise the implementation of a structured, repeated medication review with the essential roles of pharmacist, physician and nurse, into daily practice.

Factors associated with appropriate psychotropic drug prescription in nursing home patients with severe dementia

ABSTRACTBackground:We studied the patient and non-patients factors of inappropriate psychotropic drug (PD) prescription for neuropsychiatric symptoms (NPS) in nursing home patients with severe dementia. METHODS In a cross-sectional study, the appropriateness of prescriptions was explored using the Appropriate Psychotropic drug use In Dementia (APID) index sum score. This index assesses information from medical records on indication, evaluation, dosage, drug-drug interactions, drug-disease interactions, duplications, and therapy duration. Various measurements were carried out to identify the possible patient and non-patient factors. Linear multilevel regression analysis was used to identify factors that are associated with APID index sum scores. Analyses were performed for groups of PDs separately, i.e. antipsychotics, antidepressants, anxiolytics, and hypnotics. RESULTS The sample consisted of 338 patients with a PD prescription that used 147 antipsychotics, 167 antidepressants, 85 anxiolytics, and 76 hypnotics. It was found that older patients and more severe aggression, agitation, apathy, and depression were associated with more appropriate prescriptions. Additionally, less appropriate prescriptions were found to be associated with more severe anxiety, dementia diagnoses other than Alzheimer dementia, more physician time available per patient, more patients per physician, more years of experience of the physician, and higher nurses workload. CONCLUSIONS The association of more pronounced NPS with more appropriate PD prescriptions implies that physicians should pay more attention to the appropriateness of PD prescriptions when NPS are less manifest. Non-patient-related factors are also associated with the appropriateness of PD prescriptions. However, especially considering that some of these findings are counter-intuitive, more research on the topic is recommended.

Efficacy of antipsychotics in dementia depended on the definition of patients and outcomes: a meta-epidemiological study

OBJECTIVES Postulating that efficacy of antipsychotics for agitation and psychosis in dementia is best estimated in trials among patients with these symptoms and with symptom-specific outcomes, we investigated whether clinically broader definitions affected the pooled efficacy. STUDY DESIGN AND SETTING Trials were searched in multiple databases and categorized according to patient population (agitated, psychotic, and mixed) and outcome scale (agitation, psychosis, and generic). Standardized mean differences with 95% confidence intervals were calculated for conventional and atypical antipsychotics separately. RESULTS Thirty trials met our inclusion criteria. Conventional antipsychotics might have a small effect in agitated patients on agitation scales (-0.44, -0.88, 0.01) and in psychotic patients on psychosis scales (-0.31, -0.61, -0.02). There was no effect on generic scales. Efficacy of atypical antipsychotics was not established in agitated patients on agitation scales (-0.15, -0.43, 0.13) and in psychotic patients on psychosis scales (-0.11, -0.20, -0.03) but was small in mixed patients on agitation scales (-0.29, -0.40, -0.18). CONCLUSION Pooled efficacy of antipsychotics for agitation and psychosis in dementia is biased when based on trials that included patients without these target symptoms or on results measured with generic scales. This finding is important for reviewers and guideline developers who select trials for reviews.

Psychotropic drug prescription for nursing home residents with dementia: prevalence and associations with non-resident-related factors

ABSTRACT Objectives: To determine psychotropic drug prescription rates in nursing home residents with dementia and to identify associations with the so far understudied psychosocial non-resident-related factors. Method: A cross-sectional, observational, exploratory design as part of PROPER I (PRescription Optimization of Psychotropic drugs in Elderly nuRsing home patients with dementia). Participants were 559 nursing home residents with dementia, 25 physicians, and 112 nurses in the Netherlands. Psychotropic drug prescription, non-resident-related and known resident-related variables were measured to operationalize the themes of our previous qualitative analysis. Results: Fifty-six percent of residents were prescribed any psychotropic drug, 25% antipsychotics, 29% antidepressants, 15% anxiolytics, and 13% hypnotics, with large differences between the units. Multivariate multilevel regression analyses revealed that antipsychotic prescription was less likely with higher physicians’ availability (odds ratio 0.96, 95% confidence interval 0.93–1.00) and that antidepressant prescription was more likely with higher satisfaction of nurses on resident contact (odds ratio 1.50, 95% confidence interval 1.00–2.25). Resident-related factors explained 6%–15% of the variance, resident- and non-resident-related factors together 8%–17%. Conclusion: Prescription rates for antipsychotics are similar compared to other countries, and relatively low for antidepressants, anxiolytics, and hypnotics. Our findings indicate that improvement of prescribing could provisionally best be targeted at resident-related factors.
