Why do family dementia caregivers reject caregiver support services? Analyzing types of rejection and associated health-impairments in a cluster-randomized controlled intervention trial.

BACKGROUND: Although there are a number of support services accessible for most family dementia caregivers, many caregivers reject available and affordable support. Previous research suggests that rejections of support services may result from insufficient fit of available services with caregivers' unmet needs and a lack of acknowledgement of caregivers' unmet needs and associated support services. The present study investigates (a) the number, proportion and types of caregivers' rejection on recommended tailored support, (b) socio-demographic and clinical determinants of caregiver's rejection of both people with dementia (PwD) and caregivers, and (c) caregivers' health-related variables related to caregivers' rejection. METHODS: Caregivers' rejection of tailored support services was identified based on a standardized, computerized unmet needs assessment conducted by dementia-specific qualified nurses. The present analysis is based on data of n = 226 dyads of caregivers and their community-dwelling PwD who participated in a general practitioner (GP)-based, cluster-randomized intervention trial. The trial was approved by the Ethical Committee of the Chamber of Physicians of Mecklenburg-Western Pomerania, registry number BB 20/11. Data analyses were conducted using Stata/IC 13.1. We conducted Welch's t-test, Pearson's product-moment correlation, and conditional negative binomial regression models with random effects for GP to account for over-dispersed count data. RESULTS: In sum, n = 505 unmet needs were identified and the same number of tailored recommendations were identified for n = 171 family dementia caregivers from the intervention group at baseline. For n = 55 family dementia caregivers not a single unmet need and recommendation were identified. A total of 17.6% (n = 89) of the recommendations were rejected by caregivers. Rejection rates of caregivers differed by type of recommendation. Whereas caregivers' rejection rate on recommendations concerning mental health (3.6%), physical health (2.5%), and social, legal, and financial affairs (0%) were low, caregivers' rejection rates concerning social integration (especially caregiver supporting groups) was high (71.7%). Thus, the rejections of family dementia caregivers are mainly linked to the delegation to caregiver supporting groups. Caregivers' rejections were mainly related to personal factors of caregivers (n = 66), service-related factors (n = 6), relational factors (n = 1), and other factors (n = 17). Furthermore, our results showed that the number of caregivers' rejections was associated with a higher functional status of the PwD and are mainly associated with the rejection of caregiver supporting groups. Thus, caregivers visit supporting groups more often when the PwD shows low abilities in activities of daily living. Importantly, this is independent of the status of cognition and depression of the PwD as well as the physical and mental health of the family dementia caregivers. CONCLUSIONS: Our results underline the importance of understanding factors that determine caregivers' rejection of support services. These need to be specifically addressed in tailored solutions for caregivers' support services.

Cost-effectiveness of a collaborative dementia care management-Results of a cluster-randomized controlled trial.

INTRODUCTION: The purpose of this study was to determine the cost-effectiveness of collaborative dementia care management (DCM). METHODS: The cost-effectiveness analysis was based on the data of 444 patients of a cluster-randomized, controlled trial, conceptualized to evaluate a collaborative DCM that aimed to optimize treatment and care in dementia. Health-care resource use, costs, quality-adjusted life years (QALYs), and incremental cost per QALY gained were measured over a 24-month time horizon. RESULTS: DCM increased QALYs (+0.05) and decreased costs (-569€) due to a lower hospitalization and a delayed institutionalization (7 months) compared with usual care. The probability of DCM being cost-effective was 88% at willingness-to-pay thresholds of 40,000€ per QALY gained and higher in patients living alone compared to those not living alone (96% vs. 26%). DISCUSSION: DCM is likely to be a cost-effective strategy in treating dementia and thus beneficial for public health-care payers and patients, especially for those living alone.

Relatives' burden of caring for people screened positive for dementia in primary care : Results of the DelpHi study.

BACKGROUND: There is a lack of data describing caregiver burden in primary care where most (informal) caregiving is provided. OBJECTIVE: The aims of the paper are to describe the burden of people caring for persons with dementia (PWD) in primary care in multiple dimensions and to analyze factors associated with specific dimensions of caregiver burden. MATERIAL AND METHODS: Analyses are based on cross-sectional data of the general physician-based, cluster-randomized, controlled intervention trial DelpHi-MV (Dementia: life and person-centered help). A sample of n = 310 community dwelling PWD screened positive for dementia (DemTect < 9) and their caregivers provided sociodemographic and disease-related data, caregiver burden was assessed in 20 dimensions using the Berlin inventory on relatives' burden in dementia (Berliner Inventar zur Angehörigenbelastung - Demenz, BIZA-D). RESULTS: Depending on the dimension of objective burden due to caring, between 71.3 % and 92.3 % of the caregivers reported an objective burden. The average burden ranged from 3.68 to 9.81 (scale range 0-16). The subjective burden due to caring ranged from 0.1 to 1.1 (scale range 0-4). Between 22.6 and 51.6 % of our sample indicated burdens due to perceived conflicts. Logistic regression models associating caregiver burden with specifics of PWD and caregivers reached statistical significance for nearly all dimensions of the BIZA-D. Functional and cognitive impairment were statistically significant factors in 12 out of 20 and 5 out of 20 dimensions, respectively. CONCLUSION: This is first quantitative in-depth analysis of burden for caregiver of people screened positive for dementia in primary care in Germany. In general, caregiver burden was perceived as being low to moderate by caregivers and lower than reported from other settings.

Healthcare resource utilization and cost in dementia: are there differences between patients screened positive for dementia with and those without a formal diagnosis of dementia in primary care in Germany?

BACKGROUND: It is well-known that dementia is undiagnosed, resulting in the exclusion of patients without a formal diagnosis of dementia in many studies. Objectives of the present analyses were (1) to determine healthcare resource utilization and (2) costs of patients screened positive for dementia with a formal diagnosis and those without a formal diagnosis of dementia, and (3) to analyze the association between having received a formal dementia diagnosis and healthcare costs. METHOD: This analysis is based on 240 primary care patients who screened positive for dementia. Within the baseline assessment, individual data about the utilization of healthcare services were assessed. Costs were assessed from the perspective of insurance, solely including direct costs. Associations between dementia diagnosis and costs were evaluated using multiple linear regression models. RESULTS: Patients formally diagnosed with dementia were treated significantly more often by a neurologist, but less often by all other outpatient specialists, and received anti-dementia drugs and day care more often. Diagnosed patients underwent shorter and less frequent planned in-hospital treatments. Dementia diagnosis was significantly associated with higher costs of anti-dementia drug treatment, but significantly associated with less total medical care costs, which valuated to be € 5,123 compared, to € 5,565 for undiagnosed patients. We found no association between dementia diagnosis and costs of evidence-based non-medication treatment or total healthcare cost (€ 7,346 for diagnosed vs. € 6,838 for undiagnosed patients). CONCLUSION: There are no significant differences in total healthcare cost between diagnosed and undiagnosed patients. Dementia diagnosis is beneficial for receiving cost-intensive anti-dementia drug treatments, but is currently insufficient to ensure adequate non-medication treatment for community-dwelling patients.

Depressive symptoms and depression in people screened positive for dementia in primary care - results of the DelpHi-study.

BACKGROUND: Dementia and depression are common syndromes in the elderly. There is lack of knowledge concerning the frequency of depressive symptoms in people with dementia (PWD) and factors associated with depression. The aim of this analysis is to (a) describe the frequency of depressive symptoms in people screened positive for dementia, (b) describe differences between PWD with and without depressive symptoms, and (c) analyze associations between depressive symptoms and other dementia-related variables. METHODS: Analyses are based on data of the GP-based intervention trial DelpHi-MV. A sample of 430 (6.29%) people screened positive for dementia in primary care was analyzed regarding depression according to the German version of the Geriatric Depression Scale (GDS, 15-items), demographic variables, and dementia/depression-related variables. Multivariate analyses were conducted to identify factors associated with depressive symptoms. RESULTS: The mean GDS-score of depressive symptoms in n = 430 PWD was m = 3.21 (SD 2.45) with 67 PWD (15.55%) showing clinically relevant depression (GDS < 5) m = 7.71 (SD = 1.92). A total of n = 72 (16.74%) received a formal diagnosis of depression and n = 62 (14.42%) received antidepressive drug treatment. Depressive symptoms are significantly associated with age (OR = 0.93), functional impairment (OR = 1.36), and quality of life (OR = 0.01, CI: 0.00-0.06). CONCLUSION: Our results support previous findings that clinically relevant depressive symptoms are more common in people screened positive for dementia than in the general population and are often missed or mismanaged. Our findings underline the importance of managing quality of life, functional status, or depressive symptoms. Also, the results highlight the benefit of including the partner (and probably other carers) for adequate treatment of PWD.

Neuropsychiatric symptoms in people screened positive for dementia in primary care.

BACKGROUND: Neuropsychiatric symptoms are major determinants for caregiver distress and institutionalization in dementia. Little is known about the prevalence of neuropsychiatric symptoms and their association with use of medication, caregiver distress, and resource utilization in primary care. METHODS: We assessed frequency of neuropsychiatric symptoms in a sample retrieved from a primary care intervention study. Patients were screened for dementia by their primary care physicians. A study nurse assessed neuropsychiatric symptoms in 176 patients using the neuropsychiatric inventory (NPI) through face-to-face interviews by proxy during home visits. In addition, data on global cognition (MMSE), quality of life (QoL-AD), resource utilization in dementia (RUD), caregiver distress (BIS), and use of psychotropic medication in patients were obtained. We used linear mixed effect models taking into account the clustering of patients within general physician practices. RESULTS: Clinically relevant neuropsychiatric symptoms (NPI score ≥ 4) occurred in about 53% of the patients. Higher NPI scores were significantly associated with more severe cognitive impairment, higher caregiver distress, and higher utilization of caregiver resources by patients but not with a formal diagnosis of dementia from the primary care physician. Use of antipsychotics was associated with higher NPI scores, particularly in non-psychotic domains. CONCLUSIONS: Neuropsychiatric symptoms in a primary care cohort screened positive for dementia were associated with resource utilization and distress of caregivers. In contrast to guideline recommendations, the use of antipsychotics was associated with non-psychotic domains of behavioral symptoms. These findings underscore the relevance of neuropsychiatric symptoms for the design of future interventions in primary care.

The benefits of implementing a computerized intervention-management-system (IMS) on delivering integrated dementia care in the primary care setting.

BACKGROUND: A computerized Intervention-Management-System (IMS) has been developed and implemented to facilitate dementia care management. IMS is a rule-based expert decision support system that matches individual patient characteristics to a computerized knowledge base. One of the most important functionalities of IMS is to support the compilation of the individual intervention plan by systematically identifying unmet needs and suggesting the corresponding specific interventions for recommendation to the general practitioner (GP). The present analysis aimed to determine if the implementation of IMS improves the identification of unmet needs and the recommendation of adequate specific interventions. In addition, the feasibility and acceptability of the IMS were evaluated. METHODS: Delphi-MV is an on-going GP-based, cluster-randomized, controlled intervention trial to implement and evaluate a collaborative dementia care management program for community-dwelling PWDs and their caregivers. IMS was developed and implemented over the course of the DelpHi-trial. The identified unmet needs and the interventions that were recommended to the GP before and after the implementation of IMS were compared. To evaluate the feasibility and acceptability of the IMS, a survey was conducted among the current users of IMS. RESULTS AND CONCLUSIONS: After the implementation of IMS, the number of specific interventions recommended to the GP increased by 85%. Our findings provide evidence that IMS improves the systematic identification of unmet needs and the subsequent recommendation of interventions to address these needs. The users evaluated IMS as very helpful and would like to use it for their future work. However, the usability could be further improved.

Dementia care management: going new ways in ambulant dementia care within a GP-based randomized controlled intervention trial.

BACKGROUND: Increasing prevalence of dementia is a major challenge for the German healthcare system. The study DelpHi-MV ("Dementia: life- and person-centered help in Mecklenburg-Western Pomerania") aims to implement and evaluate an innovative subsidiary support system for persons with dementia (PwDs) living at home and their caregivers. METHODS: DelpHi-MV is a GP-based cluster randomized controlled intervention trial. DelpHi-Intervention aims to provide "optimum care" by integrating multi-professional and multimodal strategies to individualize and optimize treatment of dementia within the framework of the established healthcare and social service system. The intervention is conducted by Dementia Care Managers (DCMs)--nurses with dementia-specific training--at the people's homes. Based on German guidelines for evidence-based diagnoses and treatment of dementia, a comprehensive set of 95 interventio--modules--the "DelpHi-Standard"--was defined. Each module consists of predefined trigger condition(s), a subsequent intervention task, as well as at least one criterion for its completion. The intervention begins with a comprehensive assessment of the care situation, needs, and resources. The DCM develops and implements an intervention plan tailored to the individual conditions in close cooperation with the GP. EXPECTED RESULTS AND CONCLUSIONS: We expect statistically significant differences between control and intervention group in primary outcomes (quality of life, behavioral and psychological symptoms of dementia, pharmacotherapy, caregiver burden). Results can provide evidence for the effectiveness and efficacy of dementia care management according to the "Delphi-Standard"--prerequisites for implementing this concept into routine healthcare.

Who Benefits Most from Collaborative Dementia Care from a Patient and Payer Perspective? A Subgroup Cost-Effectiveness Analysis.

BACKGROUND: Dementia care management (DCM) aims to provide optimal treatment for people with dementia (PwD). Treatment and care needs are dependent on patients' sociodemographic and clinical characteristics and thus, economic outcomes could depend on such characteristics. OBJECTIVE: To detect important subgroups that benefit most from DCM and for which a significant effect on cost, QALY, and the individual cost-effectiveness could be achieved. METHODS: The analysis was based on 444 participants of the DelpHi-trial. For each subgroup, the probability of DCM being cost-effective was calculated and visualized using cost-effectiveness acceptability curves. The impact of DCM on individual costs and QALYs was assessed by using multivariate regression models with interaction terms. RESULTS: The probability of DCM being cost-effective at a willingness-to-pay of 40,000€ /QALY was higher in females (96% versus 16% for males), in those living alone (96% versus 26% for those living not alone), in those being moderately to severely cognitively (100% versus 3% for patients without cognitive impairment) and functionally impaired (97% versus 16% for patients without functional impairment), and in PwD having a high comorbidity (96% versus 26% for patients with a low comorbidity). Multivariate analyses revealed that females (b = -10,873; SE = 4,775, p = 0.023) who received the intervention had significantly lower healthcare cost. DCM significantly improved QALY for PwD with mild and moderate cognitive (b = +0.232, SE = 0.105) and functional deficits (b = +0.200, SE = 0.095). CONCLUSION: Patients characteristics significantly affect the cost-effectiveness. Females, patients living alone, patients with a high comorbidity, and those being moderately cognitively and functionally impaired benefit most from DCM. For those subgroups, healthcare payers could gain the highest cost savings and the highest effects on QALYs when DCM will be implemented.

Drug-Related Problems Increase Healthcare Costs for People Living with Dementia.

BACKGROUND: Drug-related problems (DRP) are common in the elderly population, especially in people living with dementia (PwD). DRP are associated with adverse outcomes that could result in increased costs. OBJECTIVE: The objective of the study was to analyze the association between DRP and healthcare costs in PwD. METHODS: The analysis was based on the cross-sectional data of 424 PwD. Compliance, adverse effects, and drug administration of prescribed and over-the-counter drugs taken were assessed. DRP were identified and classified by pharmacists using an adapted German version of "PIE-Doc®". Healthcare utilization was assessed retrospectively used to calculated costs from a public payer perspective using standardized unit costs. The associations between DRP and healthcare costs were analyzed using multiple linear regression models. RESULTS: 394 PwD (93%) had at least one DRP. An inappropriate drug choice was significantly associated with increased total costs (b = 2,718€; CI95% 1,448-3,988) due to significantly higher costs for hospitalization (b = 1,936€; 670-3,202) and for medications (b = 417€; 68-765). Problems with medication dosage and drug interactions were significantly associated with higher medication costs (b = 679€; 31-1,328; and b = 630€; 259-1,001, respectively). CONCLUSIONS: DRP could significantly lead to adverse outcomes for PwD and healthcare payers, reflected by a higher hospitalization and costs, respectively. Further research is needed to clarify on interventions and approaches efficiently avoiding DRP and on the effect on patient-reported and economic outcomes.

Comorbidity in Dementia Diseases and Associated Health Care Resources Utilization and Cost.

BACKGROUND: People with dementia (PwD) suffer from coexisting medical conditions, creating complex clinical challenges and increasing the risk of poor outcomes, which could be associated with high healthcare cost. OBJECTIVE: To describe the prevalence of comorbidity in PwD and to analyze the association between comorbidity in dementia diseases and healthcare costs from a payer's perspective. METHODS: This cross-sectional analysis was based on n = 362 PwD of the DelpHi-MV trial (Dementia: Life-and person-centered help in Mecklenburg-Western Pomerania). Comorbidity was assessed using the Charlson comorbidity index (CCI) and was categorized into low, high, and very high comorbidity. Healthcare resource utilization and unit costs were used to calculate costs. Multivariable regression models were applied to analyze the association between comorbidity and costs. RESULTS: Comorbidity was highly prevalent in the sample. 47% of PwD had a very high, 37% a high, and 16% a low comorbidity in addition to dementia. The most prevalent co-existing comorbidity were diabetes mellitus (42%), peripheral vascular disease (28%) and cerebrovascular disease (25%). Total costs significantly increased by 528€ (SE = 214, CI95 = 109-947, p = 0.014) with each further comorbidity, especially due to higher cost for medication and medical aids. Compared with a low comorbidity, a very high comorbidity was significantly associated with 818€ (SE = 168, CI95 = 489-1147, p < 0.001) higher medication costs and 336€ (SE = 161, CI95 = 20-652, p = 0.037) higher cost for medical aids. There were no significant association between a higher comorbidity and cost for formal care services. CONCLUSIONS: Comorbidity in PwD represents a substantial financial burden on healthcare payers and is a challenge for patients, healthcare providers, and the health systems. Innovative approaches are needed to achieve a patient-oriented management of treatment and care in comorbid PwD to reduce long-term costs.

Identifying Unmet Needs of Family Dementia Caregivers: Results of the Baseline Assessment of a Cluster-Randomized Controlled Intervention Trial.

BACKGROUND: Caregivers providing informal care for people with dementia (PwD) often report unmet needs, burden, and health impairments. Optimal support for family dementia caregivers will likely benefit from better understanding and assessment of the prevalence and types of caregivers' unmet needs and associated socio-demographic and clinical characteristics. OBJECTIVE: The present study investigates 1) the number and types of caregivers' unmet needs, 2) socio-demographic and clinical characteristics of both PwD and caregivers, and 3) caregivers' burden and health-related outcomes that are related to caregivers' unmet needs. METHODS: The present analyses are based on cross-sectional data of n = 226 dyads of caregivers and their community-dwelling PwD participating in a comprehensive standardized, computer-based caregivers' needs assessment within a general practitioner (GP)-based, cluster-randomized intervention trial. RESULTS: A total of n = 505 unmet needs were identified for n = 171 caregivers from the intervention group at baseline. Only 24.3% caregivers reported no unmet need (n = 55), whereas 75.7% caregivers had at least one unmet need (n = 171). Caregivers had on average 2.19 unmet needs (mean = 2.19, SD = 2.15). Specifically, 53.1% of caregivers had one up to three unmet needs (n = 120), 18.6% (n = 42) had three up to six unmet needs, and 4.0% (n = 9) had more than six unmet needs. DISCUSSION: Our results underline the importance of a comprehensive needs assessment for family dementia caregivers to develop and implement concepts that can provide family dementia caregivers with optimal support.

The Clock Drawing Test: A Reasonable Instrument to Assess Probable Dementia in Primary Care?

OBJECTIVE: The primary aim of the study was to determine accuracy, sensitivity and specificity of the Clock Drawing Test (CDT) in detecting probable dementia as compared to the multi-domain dementia screening test DemTect. METHODS: The sample was derived from the general practitioner (GP)-based, cluster-randomized controlled intervention trial DelpHi-MV (Dementia: life- and person-centered help in Mecklenburg-Western Pomerania). Selected from 6.440 patients systematically screened for dementia in primary care, we examined three groups (a,b,c) where the CDT (as index test) as well as the DemTect (as reference standard) were available. After excluding cases with missing values, we included a sample of n=462 with "probable dementia", n=586 with "mild cognitive impairment" and n=553 with "no cognitive impairment" matched for age and gender. We analyzed the accuracy of the CDT in identifying people with probable dementia by the DemTect and report sensitivity, and specificity for the CDT. We further analyzed age and gender differences associated with the groups. RESULTS: In comparison to the DemTect the CDT identified more than twice as many of the screened patients as cognitively impaired (63.1% in the CDT vs. 28.9% in the DemTect). The sensitivity and specificity for the CDT were 84.4% and 45.6% respectively. We found considerable age and gender differences for the performance of the CDT. Higher age (p < 0.001) and female sex (p < 0.001) were associated with incorrect clock drawings. CONCLUSION: The CDT shows a considerably high rate of false positive screening outcomes compared to the DemTect and disadvantages older people and women. Thus, in contrary to previous findings our results indicate that the CDT should not be used as exclusive instrument to screen for probable dementia in primary care.

Healthcare utilization and costs in primary care patients with dementia: baseline results of the DelpHi-trial.

The objectives of this cross-sectional analysis were to determine healthcare resource utilization and cost for community-dwelling patients with dementia (PWD) from a payer's and societal perspective, and to analyze the associations between costs and sociodemographic and clinical variables. Analysis of healthcare costs from a payer's perspective was based on a sample of 425 PWD, analysis of healthcare costs from societal perspective on a subsample of 254 PWD and their informal caregivers. Frequency of healthcare resource utilization was assessed by means of questionnaires. Informal care and productivity losses were assessed by using the Resource Utilization in Dementia questionnaire (RUD). Costs were monetarized using standardized unit costs. To analyze the associations, multiple linear regression models were used. Total annual costs per PWD valued 7016€ from a payer's and 25,877€ from a societal perspective, meaning that societal cost is approximately three and a half times as much as payer's expenditures. Costs valuated 5456 € for medical treatments, 1559 € for formal care, 18,327€ for informal care. Productivity losses valued 1297€ for PWD caregivers. Informal care could vary substantially (-21%; +33%) concerning different valuation methods. Medical care costs decreased significantly with progression of dementia and with age. Costs of care double over the stages of dementia. Formal care costs were significantly higher for PWD living alone and informal care costs significantly lower for PWD with an employed caregiver. For all cost categories, deficits in daily living activities were major cost drivers.

Patient Variables Associated with the Assignment of a Formal Dementia Diagnosis to Positively Screened Primary Care Patients.

BACKGROUND: Main objective was to analyze the associations of patient variables (depression, quality of life, anti-dementia drug treatment, knowledge about dementia) with the assignment of a formal diagnosis of dementia to community-dwelling primary care patients who have screened positive for dementia. METHODS: DelpHi-MV (Dementia: life- and person-centered help in Mecklenburg-Western Pomerania) is a general practitioner based randomized controlled intervention trial. Present analyses are based on cross-sectional data of 319 positively screened patients (age 70+, living at home) who had not been formally diagnosed with dementia before the screening. The medical diagnoses (ICD-10) were retrieved from the patient's medical records. Depression (Geriatric Depression Scale; GDS), quality of life in Alzheimer's disease (Qol-AD), knowledge about dementia, and anti-dementia drug treatment were assessed after the screening test at the baseline examination. RESULTS: At the baseline examination, 171 out of 319 patients (54%) had been formally diagnosed with dementia after they have screened positive. Univariate comparisons showed no statistically significant differences between diagnosed and undiagnosed patients regarding depression (GDS≥6: 11% vs. 15%; p=0.396), quality of life (mean (SD): 2.8 (0.3) vs. 2.8 (0.4); p=0.833), and the knowledge about dementia (75% vs. 75%; p>0.999). Patients who had received a formal diagnosis were more often treated with anti-dementia drugs (20% vs. 11%; p=0.040). Multivariate analyses controlled for confounding variables confirmed these findings. CONCLUSION: Present findings do not support concerns that the assignment of a formal dementia diagnosis after screening is associated with potential harms. If confirmed in a prospective study, our data would suggest that patients may benefit from being formally diagnosed regarding anti-dementia drug treatment.

Potentially Inappropriate Medication in Community-Dwelling Primary Care Patients who were Screened Positive for Dementia.

BACKGROUND: Potentially inappropriate medication (PIM) in older people is a risk factor for adverse drug effects. This risk is even higher in older people with dementia (PWD). OBJECTIVE: Our study aimed to determine (1) the prevalence of PIM among primary care patients who were screened positive for dementia and (2) the sociodemographic and clinical variables associated with the use of PIM. METHODS: DelpHi-MV (Dementia: life- and person-centered help in Mecklenburg-Western Pomerania) is a general practitioner-based, cluster-randomized, controlled intervention study to implement and evaluate an innovative concept of collaborative dementia care management in Germany. The comprehensive baseline assessment includes a home medication review. The present analyses are based on the data from 448 study participants (age 70+, DemTect <9). PIMs were identified using the list of Potentially Inappropriate Medications in the Elderly (Priscus). RESULTS: (1) A total of 99 study participants (22%) received at least one PIM. The highest prevalence was found for antidepressants, benzodiazepines, and analgetics. The most frequently prescribed PIMs were amitriptyline, etoricoxib, and doxazosin. (2) Use of a PIM was significantly associated with a diagnosis of a mental or behavioral disorder. CONCLUSIONS: The prescription rate of PIMs for community-dwelling PWD was comparable with the rates found for the general population of older people in Germany (20-29%). Antidepressants with anticholinergic properties and long-acting benzodiazepines were the most prescribed PIMs, despite having an unfavorable benefit-risk ratio. This high prevalence of PIM prescriptions in a vulnerable population of PWD indicates that standard care for dementia should include careful medication review and management.

Effectiveness and Safety of Dementia Care Management in Primary Care: A Randomized Clinical Trial.

Importance: Dementia care management (DCM) can increase the quality of care for people with dementia. Methodologically rigorous clinical trials on DCM are lacking. Objective: To test the effectiveness and safety of DCM in the treatment and care of people with dementia living at home and caregiver burden (when available). Design, Setting, and Participants: This pragmatic, general practitioner-based, cluster-randomized intervention trial compared the intervention with care as usual at baseline and at 12-month follow-up. Simple 1:1 randomization of general practices in Germany was used. Analyses were intent to treat and per protocol. In total, 6838 patients were screened for dementia (eligibility: 70 years and older and living at home) from January 1, 2012, to March 31, 2016. Overall, 1167 (17.1%) were diagnosed as having dementia, and 634 (9.3%) provided written informed consent to participate. Interventions: Dementia care management was provided for 6 months at the homes of patients with dementia. Dementia care management is a model of collaborative care, defined as a complex intervention aiming to provide optimal treatment and care for patients with dementia and support caregivers using a computer-assisted assessment determining a personalized array of intervention modules and subsequent success monitoring. Dementia care management was targeted at the individual patient level and was conducted by 6 study nurses with dementia care-specific qualifications. Main Outcomes and Measures: Quality of life, caregiver burden, behavioral and psychological symptoms of dementia, pharmacotherapy with antidementia drugs, and use of potentially inappropriate medication. Results: The mean age of 634 patients was 80 years. A total of 407 patients received the intended treatment and were available for primary outcome measurement. Of these patients, 248 (60.9%) were women, and 204 (50.1%) lived alone. Dementia care management significantly decreased behavioral and psychological symptoms of dementia (b = -7.45; 95% CI, -11.08 to -3.81; P < .001) and caregiver burden (b = -0.50; 95% CI, -1.09 to 0.08; P = .045) compared with care as usual. Patients with dementia receiving DCM had an increased chance of receiving antidementia drug treatment (DCM, 114 of 291 [39.2%] vs care as usual, 31 of 116 [26.7%]) after 12 months (odds ratio, 1.97; 95% CI, 0.99 to 3.94; P = .03). Dementia care management significantly increased quality of life (b = 0.08; 95% CI, 0 to 0.17; P = .03) for patients not living alone but did not increase quality of life overall. There was no effect on potentially inappropriate medication (odds ratio, 1.86; 95% CI, 0.62 to 3.62; P = .97). Conclusions and Relevance: Dementia care management provided by specifically trained nurses is an effective collaborative care model that improves relevant patient- and caregiver-related outcomes in dementia. Implementing DCM in different health care systems should become an active area of research. Trial Registration: clinicaltrials.gov Identifier: NCT01401582.

Qualifications for nurses for the care of patients with dementia and support to their caregivers: A pilot evaluation of the dementia care management curriculum.

BACKGROUND: A substantial increase of people with dementia (PwD) is predicted for the future. Nurses are taking over important tasks to support PwD, which requires a specialized qualification. OBJECTIVES: The aim was to identify points for revision and to further improve the Dementia Care Manager (DCM) curriculum as a basis for probable qualification of nurses caring for PwD. DESIGN: We conducted a summative evaluation study to revise the first version of the DCM curriculum. SETTING: The study was conducted in the primary health care setting. PARTICIPANTS: Nurses and lecturers of the first theoretical and practical implementation were involved. METHODS: Questionnaire-based interviews with nurses and lecturers after every module during the theoretical qualification. Besides, nurses rated the curriculum after the end of the theoretical part and evaluated the DCM tasks and the usefulness of the curriculum contents after the practical phase in questionnaire-based interviews. Descriptive statistics were used for analysis. RESULTS: A total of five nurses and 33 lecturers participated in the first theoretical and practical implementation of the DCM qualification. Generally, nurses and lecturers assessed the curriculum contents as "very important" or "important." In particular, the job-related issues, the variety of course topics and the close combination of theory and practice were highly valued. The practical implementation of the DCM was rated predominantly as "important" by nurses for the delivery of care for PwD. To optimize the theoretical DCM curriculum, participants suggested increasing the number of lessons for two of the modules (gerontopsychiatry, interdisciplinary case reviews). Furthermore, nurses preferred a longer practical phase, whereas some lecturers called for larger group sizes of participants. CONCLUSIONS: The DCM qualification enhances nurses' competencies to care for PwD. The curriculum regards an interprofessional, cooperative team approach as the potential to improve health care supply for demented people and to better support their caregivers.

Economic Analysis of Formal Care, Informal Care, and Productivity Losses in Primary Care Patients who Screened Positive for Dementia in Germany.

BACKGROUND: The majority of people with dementia (PwD) live at home and require professional formal care and informal care that is generally provided by close relatives. OBJECTIVE: To determine the utilization and costs of formal and informal care for PwD, indirect costs because of productivity losses of caregivers, and the associations between cost, socio-demographic and clinical variables. METHODS: The analysis includes the data of 262 community-dwelling PwD and their caregivers. Socio-demographics, clinical variables, and the utilization of formal care were assessed within the baseline assessment. To evaluate informal care costs, the Resource Utilization in Dementia (RUD) questionnaire was used. Costs were calculated from a social perspective. Associations were evaluated using multiple linear and logistic regression models. RESULTS: Formal care services were utilized less (26.3%) than informal care (85.1%), resulting in a cost ratio of one to ten(1,646 €; 16,473 €, respectively). In total, 29% of caregivers were employed, and every seventh (14.3%) experienced productivity losses, which corresponded to 1,258 € annually. Whereas increasing deficits in daily living activities were associated with higher formal and higher informal costs, living alone was significantly associated with higher formal care costs and the employment of a caregiver was associated with lower informal care costs. CONCLUSION: Informal care contributes the most to total care costs. Living alone is a major cost driver for formal costs because of the lower availability of potential informal care. The availability of informal care is limited and productivity losses are increased when a caregiver is employed.
