ABSTRACT

INTRODUCTION: Dementia is among the costliest of medical conditions, but it is not known how these costs vary by dementia subtype. METHODS: The effect of dementia diagnosis subtype on direct health care costs and utilization was estimated using 2015 California Medicare fee-for-service data. Potential drivers of increased costs in Lewy body dementia (LBD), in comparison to Alzheimer's disease, were tested. RESULTS: 3,001,987 Medicare beneficiaries were identified, of which 8.2% had a dementia diagnosis. Unspecified dementia was the most common diagnostic category (59.6%), followed by Alzheimer's disease (23.2%). LBD was the costliest subtype to Medicare, on average, followed by vascular dementia. The higher costs in LBD were explained in part by falls, urinary incontinence or infection, depression, anxiety, dehydration, and delirium. DISCUSSION: Dementia subtype is an important predictor of health care costs. Earlier identification and targeted treatment might mitigate the costs associated with co-occurring conditions in LBD.

ABSTRACT

OBJECTIVE: To investigate the use of formal care during the first three years after diagnosis of mild dementia and identify cost-predicting factors. DESIGN: Prospective longitudinal study over three years. SETTING: An incidence-based bottom-up cost-of-illness study where information about formal health care services was drawn from the municipalities' registers during the first three years after the diagnosis of mild dementia. PARTICIPANTS: 109 patients with mild dementia at baseline, diagnosed according to consensus criteria based on standardized assessments. MEASUREMENT: The use of formal care as registered by the municipalities' registration systems. Costs were estimated by applying unit costs, including municipal expenses and out-of-pocket contributions. Clinical data were collected at baseline to identify cost-predicting factors. RESULTS: Costs for formal care were increasing from € 535 per month of survival (MOS) at baseline to € 3,611 per MOS during the third year, with a mean of € 2,420 during the whole observation period. The major cost driver (74%) was institutional care. The costs for people with dementia with Lewy bodies (€ 3,247 per MOS) were significantly higher than for people with Alzheimer disease (€ 1,855 per MOS). The most important cost-predicting factors we identified were the living situation, a diagnosis of non-Alzheimer disease, comorbidity, and daily living functioning. The use of cholinesterase inhibitors was related to lower costs. CONCLUSION: Formal care costs increased significantly over time with institutional care being the heaviest cost driver. Studies with longer observation periods will be necessary to evaluate the complete socioeconomic impact of the course of dementia.

ABSTRACT

OBJECTIVES: Age-related dementia is a progressive degenerative brain syndrome whose prevalence increases with age. Dementias cause a substantial burden on society and on families who provide informal care. This study aims to review the relevant papers to compare informal care time and costs in different dementias. METHODS: A bibliographic search was performed on an international medical literature database (MEDLINE). All studies which assessed the social economic burden of different dementias were selected. Informal care time and costs were analyzed in three care settings by disease stages. RESULTS: 21 studies met our criteria. Mean informal care time was 55.73 h per week for Alzheimer disease and 15.8 h per week for Parkinson disease (P = 0.0076), and the associated mean annual informal costs were $17,492 versus $3,284, respectively (P = 0.0393). CONCLUSION: There is a lack of data about informal care time and costs among other dementias than AD or PD. Globally, AD is the most costly in terms of informal care costs than PD, $17,492 versus $3,284, respectively.

ABSTRACT

OBJECTIVE: To assess the cost effectiveness of cholinesterase inhibitor (ChEI) treatment in patients with Alzheimer's disease (AD) and Dementia with Lewy bodies (DLB). METHOD: We used 4-month open label follow-up data from routine memory clinic patients. There were 852 patients with AD and 112 with DLB. We applied three predictive models to estimate clinical and economic outcomes at five years, comparing AD and DLB patients with hypothetical untreated controls. RESULTS: The mean improvement in MMSE in 852 AD patients was 0.57 (SD 3.4) at 4 months, and in the subgroup with baseline MMSE of 10-20 (moderate) was 1.6 (SD 3.7). Overall, the 112 DLB patients improved by 1.4 (SD 3.7). DLB patients with an MMSE 10-20 improved by 3.1 (SD 4.5) points. These efficacy data were input into the SHTAC, microsimulation and Markov models and produced estimated costs per QALY gained (CQG) for all AD of pound194,066, pound67,904 and pound123,935 respectively. In comparison, the CQGs for all DLB were pound46,794, pound2,706 and pound35,922. For the moderate subgroups only the SHTAC and microsimulation models were applicable. These gave CQG estimates for moderate AD of pound39,664 and cost saving respectively. For moderate DLB, both estimates were cost saving. CONCLUSION: The cost per QALY gained of cholinesterase treatment of all patients with DLB (including those with MMSE outside the 10-20 range) is comparable to that of patients with moderate AD, and is probably cost saving.

ABSTRACT

BACKGROUND: The objective of this study was to compare total costs of care and its major components for community-living patients with Alzheimer's disease (AD) or dementia with Lewy bodies (DLB). This cross-sectional analysis of baseline data from the Predictors II Study took place in three university-based AD centers in the U.S. METHODS: Community-living patients clinically diagnosed with probable AD (n = 170) or DLB (n = 25) with a modified Mini-Mental State examination (mMMS) score > or =30, equivalent to a score of approximately > or =16 on the Folstein Mini-Mental State Examination (MMSE), participated in this study. Patient and informant reported on patients' use of direct medical care, direct nonmedical care, and informal care. Patients' clinical and demographic characteristics included global cognitive status (measured by MMSE), functional capacity (measured by Blessed Dementia Rating Scale), psychotic symptoms, behavioral problems, depressive symptoms, extrapyramidal signs, comorbidities, age, and sex. Costs were compared by using covariate matching methods. RESULTS: Unadjusted total costs and direct medical costs were not significantly different between AD and DLB patients. Compared with AD patients, unadjusted indirect costs were significantly higher and unadjusted direct nonmedical costs were significantly lower among DLB patients. After adjusting for age, sex, cognitive and functional status, differences in all cost components between DLB and AD patients were no longer statistically significant. CONCLUSIONS: Apparent cost differences were largely attributed to differences in patients' cognitive and functional status. However, the small sample size for DLB patients might have limited power to detect statistically significant differences in costs of care between these groups.

ABSTRACT

The purpose of this study was to examine the strength of the associations between 5 measures of need that are potentially modifiable in degenerative dementia patients and direct costs of care from 5 payer perspectives in the US healthcare system. Data were derived from a cohort study of 150 patients with a degenerative dementia. We measured need variables at baseline and utilization of healthcare in the year before and after baseline. Utilization data were converted into estimated direct costs and totaled based on the costs paid for by 5 payers in the US healthcare system. Path models were used to quantify and compare the relationships between need variables and direct costs. From Medicare's perspective, comorbid medical conditions were the most important predictor of Medicare costs. From Medicaid's perspective, neuropsychiatric symptoms and signs of parkinsonism were additional significant predictors. From the perspective of patients, their families and society, all 5 need variables were significant predictors of direct costs (ie, those above, plus cognitive impairment, and dependency). The relationship between evaluated need variables and direct costs depends on the perspective of the payer and provide insights into which need variables could be targeted with interventions to control costs and improve patient outcomes.

ABSTRACT

OBJECTIVES: The purpose of this study was to compare resource use and costs in patients with dementia with Lewy bodies (DLB) and Alzheimer's disease (AD) and to assess determinants of costs of care in DLB. METHOD: Thirty-four patients with DLB were included in a cross-sectional study. The patients were matched with respect to age, gender and Mini Mental State Examination (MMSE) score to 34 patients with AD. Both groups were examined using Resource Utilisation in Dementia (RUD Lite), MMSE and the Neuropsychiatric inventory (NPI). The DLB patients were additionally examined using the Disability Assessment for Dementia Scale (DAD). RESULTS: Costs of care in patients suffering from DLB was on average 348,000 SEK (37,500 euro) per year compared to 169,000 SEK (18,200 euro) in the AD group (p < 0.001). Within the DLB group, care costs correlated significantly (r(c) = 2.77, p < 0.001) with dependency in instrumental activities of daily living measured with DAD, whereas MMSE and NPI were not significantly correlated to resource use in the DLB group. CONCLUSIONS: DLB patients use more resources, and are more costly than AD patients. Dependency in instrumental activities of daily living is strongly correlated to resource use in DLB patients.

ABSTRACT

OBJECTIVE: To compare the annual direct costs for patients with Alzheimer's disease (AD) and no parkinsonism (AD), patients with AD and parkinsonism (AD/P), and patients with dementia with Lewy bodies (DLB). For the entire sample, the authors examined the incremental costs associated with increasing parkinsonism. METHODS: Cross-sectional comparisons of 1 year of direct costs were done. Fifteen patients met criteria for DLB, and 133 met criteria for probable AD, of whom 39 had signs of parkinsonism and 94 did not. Patients' caregivers reported on the patient's use of health care services, receipt of unpaid care, and comorbid medical conditions. Severity of cognitive impairment and parkinsonism were determined during patient examinations. Costs were estimated by multiplying utilization data by a unit cost for each type of care. Costs were compared after adjustment for covariates using multiple regression equations. RESULTS: After adjusting for important covariates, patients with AD/P or DLB had significantly higher annual direct costs than patients with AD. The average adjusted increases in costs above the AD baseline costs were 7,119 dollars (AD/P) and 13,754 dollars (DLB) for formal direct costs and 7,394 dollars (AD/P) and 19,564 dollars (DLB) for total direct costs. Models for the entire sample estimated that a 1-point increase in a parkinsonism scale would result in an annual increase of 784 dollars in formal costs and 827 dollars in total costs of care. CONCLUSIONS: Patients with Alzheimer's disease and parkinsonism or dementia with Lewy bodies have significantly higher formal and total direct costs of care than patients with Alzheimer's disease. Signs of parkinsonism in patients with degenerative dementias are significant independent predictors of costs of care.
