Rates of 30-day revisit to the emergency department among older adults living with dementia: a systematic review and meta-analysis. CAN J EMERG MED 2023; 25:884-892. [PMID: 37659987 DOI: 10.1007/s43678-023-00578-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Accepted: 08/09/2023] [Indexed: 09/04/2023]
Abstract
OBJECTIVE Older adults visit emergency departments (EDs) at higher rates than their younger counterparts. However, less is known about the rate at which older adults living with dementia visit and revisit EDs. We conducted a systematic review and meta-analysis to quantify the revisit rate to the ED among older adults living with a dementia diagnosis. METHODS We searched MEDLINE, Embase, and CINAHL, as well as gray literature, to identify observational studies reporting on older adults living with dementia that revisited an ED within 30 days of a prior ED visit. We calculated pooled rates of 30-day revisit as percentages using random effects models, and conducted stratified analyses by study data source, study population, and study period. We assessed between-studies heterogeneity using the I2 statistic and considered [Formula: see text] > 50% to indicate substantial heterogeneity. All analyses were performed in R software. RESULTS We identified six articles for inclusion. Percentages of 30-day ED revisit among older adults living with dementia ranged widely from 16.1% to 58.0%. The overall revisit rate of 28.6% showed significant heterogeneity. Between-studies heterogeneity across all stratified analyses was also high. By data source, 30-day revisit percentages were 52.3% (public hospitals) and 20.0% (administrative databases); by study population, revisit percentages were 33.5% (dementia as main population) and 19.8% (dementia as a subgroup). By study period, revisit percentages were 41.2% (5 years or greater) and 18.9% (5 years or less). CONCLUSION Existing literature on ED revisits among older adults living with dementia highlights the medical complexities and challenges surrounding discharge and follow-up care that may cause these patients to seek ED care at an increased rate. ED personnel may play an important role in connecting patients and caregivers to more appropriate medical and social resources in order to deliver an efficient and more rounded approach to care.

Abstract
OBJECTIVES This study aimed to determine the feasibility and acceptability of a multi-modal performing arts intervention (MPAI) for caregivers of people with mild to moderately severe dementia. The secondary objective was to examine how MPAI might change caregiver burden, caregiver resiliency, and perceived quality of life (QoL) for care recipients. METHOD The study features a mixed-methods design. Caregivers (N = 32) completed the Zarit Burden Interview (caregiver burden) Brief Resilience Scale (resiliency) and Quality of Life-Alzheimer's disease measure (care recipient QoL) at five study timepoints. Semi-structured interviews (N = 15) documented the intervention's acceptability and caregivers' subjective experiences. Feasibility was indexed through withdrawal and attendance analysis. Braun and Clarke (2006) thematic analysis guided the qualitative analysis. RESULTS Caregiver burden significantly declined from baseline through final follow-up. Caregiver resiliency and care recipient QoL were not significantly changed but trended up during the intervention until it dropped at the end of the program. Qualitative data suggests the reversal in resiliency and QoL may be explained by caregivers' increased anxiety as the program ended. Acceptability data indicated caregivers were unanimously highly satisfied with the intervention, desiring to continue participation. Feasibility findings provide recommendations for intervention improvements. CONCLUSION MPAI could reduce caregiver burden and increase resilience for informal caregivers of a person with dementia. Effects drop off quickly at the end of the program, indicating the need for ongoing interventions that provide social support, a respite from the pressures of care recipients' dependency, and the relief that caregivers experience when they perceive benefits to their care recipient's well-being.

Abstract
OBJECTIVES This study aimed to examine the influence of cognitive impairment on preventive health services utilization among older adults. METHODS The study sample came from 1995 to 2014 waves of the Health and Retirement Study (HRS), consisting of 19,644 adults aged 51 years or older. Mixed-effects logistic regression was used to analyze the influence of cognitive impairment, measured using the Telephone Interview for Cognitive Status, on the utilization of four types of preventive health care services, including flu shots, cholesterol tests, mammography for women, and prostate cancer screening for men. RESULTS Persons with cognitive impairment with no dementia were less likely to receive cholesterol tests (OR=0.68, 95% CI=0.64-0.73, p<.001), flu shots (OR=0.86, CI=0.80-0.92, p<.001), mammograms (OR=0.88, CI=0.78-0.99, p<.05), and prostate cancer screenings (OR=0.71, CI=0.71-0.98, p<.05) compared with those without cognitive impairment. Having dementia was associated with a lower odds of receiving cholesterol tests (OR=0.42, CI=0.38-0.47, p<.001), flu shots (OR=0.65, CI=0.57-0.74, p<.001), mammograms (OR=0.70, CI=0.55-0.89, p<.01), and prostate cancer screening (OR=0.68, CI=0.47-0.99, p<.05). CONCLUSIONS Cognitive impairment with or without dementia is a significant barrier to utilizing preventive health services among older adults. Targeted health promotion prevention and intervention strategies and caregiver education are warranted to improve preventive services among older adults with cognitive impairment.

Abstract
BACKGROUND Although one third of Medicare beneficiaries are enrolled in Medicare Advantage (MA) plans, there is limited information about the cost of treating Alzheimer disease and related dementias (ADRD) in these settings. OBJECTIVE The objective of this study was to estimate direct health care costs attributable to ADRD among older adults within a large MA plan. RESEARCH DESIGN A retrospective cohort design was used to estimate direct total, outpatient, inpatient, ambulatory pharmacy, and nursing home costs for 3 years before and after an incident ADRD diagnosis for 927 individuals diagnosed with ADRD relative to a sex-matched and birth year-matched set of 2945 controls. SUBJECT Adults 65 years of age and older enrolled in the Kaiser Permanente Washington MA plan and the Adult Changes in Thought (ACT) Study, a prospective longitudinal cohort study of ADRD and brain aging. MEASURES Data on monthly health service use obtained from health system electronic medical records for the period 1992-2012. RESULTS Total monthly health care costs for individuals with ADRD are statistically greater (P<0.05) than controls beginning in the third month before diagnosis and remain significantly greater through the eighth month following diagnosis. Greater total health costs are driven by significantly (P<0.05) greater nursing home costs among individuals diagnosed with ADRD beginning in the third month prediagnosis. Although total costs were no longer significantly greater at 8 months following diagnosis, nursing home costs remained higher for the people with dementia through the 3 years postdiagnosis we analyzed. CONCLUSION Greater total health care costs among individuals with ADRD are primarily driven by nursing home costs.

Abstract
OBJECTIVES We conducted a systematic review of studies reporting the direct healthcare costs of treating older adults with diagnosed Alzheimer disease and related dementias (ADRD) within private Medicare managed care plans. STUDY DESIGN A systematic review of all studies published in English reporting original empirical analyses of direct costs for older adults with ADRD in Medicare managed care. METHODS All papers indexed in PubMed or Web of Science reporting ADRD costs within Medicare managed care plans from 1983 through 2018 were identified and reviewed. RESULTS Despite the growth in Medicare managed care enrollment, only 9 papers report the costs of care for individuals with ADRD within these plans, and only 1 study reports data less than 10 years old. This limited literature reports wide ranges for ADRD-attributable costs, with estimates varying from $3738 to $8726 in annual prevalent costs and $8938 to $38,794 in 1-year immediate postdiagnosis incident costs. Reviewed studies also used varied study populations, case and cost ascertainment methods, and analytic methods, making cross-study comparisons difficult. CONCLUSIONS The expected continued growth in Medicare managed care enrollment, coupled with the large and growing impact of ADRD on America's healthcare delivery and finance systems, requires more research on the cost of ADRD within managed care. This research should use more consistent approaches to identify ADRD prevalence and provide more detail regarding which components of care are included in analyses and how the costs of care are captured and measured.

Predictors of high hospital care and medication costs and cost trajectories in community-dwellers with Alzheimer's disease. Ann Med 2019; 51:294-305.

Abstract
Objectives: We studied the determinants of high healthcare costs (highest decile of hospital care and medication costs) and cost trajectories among all community-dwellers with clinically verified Alzheimer's disease (AD), diagnosed during 2005-2011 in Finland (N = 70,531). Methods: The analyses were done separately for hospital care costs, medication costs and total healthcare costs that were calculated for each 6-month period from 5 years before to 3 years after AD diagnosis. Results: Total healthcare costs were driven mainly by hospital care costs. The definition of "high-cost person" was time-dependent as 63% belonged to the highest 10% at some timepoint during the study period and six distinct cost trajectories were identified. Strokes, cardiovascular diseases, fractures and mental and behavioural disorders were most strongly associated with high hospital care costs. Conclusions: Although persons with AD are often collectively considered as expensive patient group, there is large temporal and inter-individual variation in belonging to the highest decile of hospitalization and/or medication costs. It would be important to assess whether hospitalization rate could be decreased by, e.g., comprehensive outpatient care with more efficient management of comorbidities. In addition, other interventions that could decrease hospitalization rate in persons with dementia should be studied further in this context. Key messages Persons with AD had large individual fluctuation in hospital care costs and medication costs over time. Hospital care costs were considerably larger than medication costs, with fractures, cardiovascular diseases and mental and behavioural disorders being the key predictors. Antidementia medication was associated with lower hospital care costs.

Abstract
Objectives To develop a simple dementia screening tool to assist primary care physicians in identifying patients with cognitive impairment among subjects with memory complaints or at a high risk for dementia. Design The Brain Health Test (BHT) was developed by several experienced neurologists, psychiatrists, and clinical psychologists in the Taiwan Dementia Society. Validation of the BHT was conducted in the memory clinics of various levels of hospitals in Taiwan. Participants All dementia patients at the memory clinics who met the inclusion criteria of age greater or equal to 50 years were enrolled. Besides the BHT, the Mini-Mental State Examination and Clinical Dementia Rating were used to evaluate the cognition state of the patients and the severity of dementia. Results The BHT includes two parts: a risk evaluation and a cognitive test (BHT-cog). Self or informants reports of memory decline or needing help from others to manage money or medications were significantly associated with cognitive impairment. Among the risk factors evaluated in the BHT, a total risk score greater or equal to 8 was defined as a high risk for dementia. The total score for the finalized BHT-cog was 16. When the cutoff value for the BHT-cog was set to 10 for differentiating dementia and a normal mental state, the sensitivity was 91.5%, the specificity was 87.3%, the positive predictive value was 94.8%, and the negative predictive value was 80.1% The area under the receiver operating characteristic curve between dementia and healthy subjects was 0.958 (95% CI = 0.941–0.975). Conclusions The BHT is a simple tool that may be useful in primary care settings to identify high-risk patients to target for cognitive screening.

Abstract
OBJECTIVE The challenges posed by people living with multiple chronic conditions are unique for people with dementia and other significant cognitive impairment. There have been recent calls to action to review the existing literature on co-occurring chronic conditions and dementia in order to better understand the effect of cognitive impairment on disease management, mobility, and mortality. METHODS This systematic literature review searched PubMed databases through 2011 (updated in 2016) using key constructs of older adults, moderate-to-severe cognitive impairment (both diagnosed and undiagnosed dementia), and chronic conditions. Reviewers assessed papers for eligibility and extracted key data from each included manuscript. An independent expert panel rated the strength and quality of evidence and prioritized gaps for future study. RESULTS Four thousand thirty-three articles were identified, of which 147 met criteria for review. We found that moderate-to-severe cognitive impairment increased risks of mortality, was associated with prolonged institutional stays, and decreased function in persons with multiple chronic conditions. There was no relationship between significant cognitive impairment and use of cardiovascular or hypertensive medications for persons with these comorbidities. Prioritized areas for future research include hospitalizations, disease-specific outcomes, diabetes, chronic pain, cardiovascular disease, depression, falls, stroke, and multiple chronic conditions. CONCLUSIONS This review summarizes that living with significant cognitive impairment or dementia negatively impacts mortality, institutionalization, and functional outcomes for people living with multiple chronic conditions. Our findings suggest that chronic-disease management interventions will need to address co-occurring cognitive impairment. Copyright © 2017 John Wiley & Sons, Ltd.

Abstract
Understanding expenditure patterns for hospital and emergency department (ED) use among individuals with dementia is crucial to controlling Medicare spending. We analyzed Health and Retirement Study data and Medicare claims, stratified by beneficiaries' residence and proximity to death, to estimate Medicare expenditures for all-cause and potentially avoidable hospitalizations and ED visits. Analysis was limited to the Medicare fee-for-service population age 65 and older. Compared with people without dementia, community residents with dementia had higher average expenditures for hospital and ED services; nursing home residents with dementia had lower average expenditures for all-cause hospitalizations. Decedents with dementia had lower expenditures than those without dementia in the last year of life. Medicare expenditures for individuals with and without dementia vary by residential setting and proximity to death. Results highlight the importance of addressing the needs specific to the population with dementia. There are many initiatives to reduce hospital admissions, but few focus on people with dementia.

Abstract
Although persons with dementia are frequently hospitalized, relatively little is known about the health profile, patterns of health care use, and mortality rates for patients with dementia who access care in the emergency department (ED). We linked data from our hospital system with Medicare and Medicaid claims, Minimum Data Set, and Outcome and Assessment Information Set data to evaluate 175,652 ED visits made by 10,354 individuals with dementia and 15,020 individuals without dementia over 11 years. Survival rates after ED visits and associated charges were examined. Patients with dementia visited the ED more frequently, were hospitalized more often than patients without dementia, and had an increased odds of returning to the ED within 30 days of an index ED visit compared with persons who never had a dementia diagnosis (odds ratio, 2.29; P<0.001). Survival rates differed significantly between patients by dementia status (P<0.001). Mean Medicare payments for ED services were significantly higher among patients with dementia. These results show that older adults with dementia are frequent ED visitors who have greater comorbidity, incur higher charges, are admitted to hospitals at higher rates, return to EDs at higher rates, and have higher mortality after an ED visit than patients without dementia.

Abstract
Objective: The aim of this study was to explore gender and race-specific mortality and comorbidities associated with dementia hospitalizations among the oldest-old. Method: Using the 1999-2008 Nationwide Inpatient Sample, we identified the association between dementia mortality and hospital characteristics in the oldest-old population. Results: The oldest-old population was mostly comprised of Whites (81.1%) and women (76.0%), had shorter length of hospital stay (6.12 days), and lower hospital charges (US$18,770.32) than the young-old, despite the higher in-hospital mortality. Crude in-hospital mortality was higher for White males in the young-old population, followed by Hispanics and African Americans. However, Hispanic males had the highest mortality, followed by Whites then African Americans in the oldest-old group. After adjusting for different variables, these relationships did not change. Discussion: There should be a greater focus on potential pre-existing biases regarding hospital care in the elderly, especially the oldest-old and elderly minority groups.

Abstract
BACKGROUND Approximately 3.2 million hospital stays annually involve a person with dementia, leading to higher costs, longer lengths of stay, and poorer outcomes. Older adults with dementia are vulnerable when hospitals are unable to meet their special needs. METHODS We developed, implemented, and evaluated a training program for 540 individuals at 4 community hospitals. Pretest, posttest, and a 120-day delayed posttest were performed to assess knowledge, confidence, and practice parameters. RESULTS The mean age of the sample was 46 years; 83% were White, 90% were female, and 60% were nurses. Upon completion, there were significant gains (P's <0.001) in knowledge and confidence in recognizing, assessing, and managing dementia. Attendees reported gains in communication skills and strategies to improve the hospital environment, patient safety, and behavioral management. At 120 days, 3 of 4 hospitals demonstrated maintenance of confidence. In the hospital that demonstrated lower knowledge and confidence scores, the sample was older and had more nurses and more years in practice. CONCLUSIONS We demonstrate the feasibility of training hospital staff about dementia and its impact on patient outcomes. At baseline, there was low knowledge and confidence in the ability to care for dementia patients. Training had an immediate impact on knowledge, confidence, and attitudes with lasting impact in 3 of 4 hospitals. We identified targets for intervention and the need for ongoing training and administrative reinforcement to sustain behavioral change. Community resources, such as local chapters of the Alzheimer Association, may be key community partners in improving care outcomes for hospitalized persons with dementia.

Abstract
BACKGROUND Over 35 million people are estimated to be living with dementia in the world and the societal costs are very high. Case management is a widely used and strongly promoted complex intervention for organising and co-ordinating care at the level of the individual, with the aim of providing long-term care for people with dementia in the community as an alternative to early admission to a care home or hospital. OBJECTIVES To evaluate the effectiveness of case management approaches to home support for people with dementia, from the perspective of the different people involved (patients, carers, and staff) compared with other forms of treatment, including 'treatment as usual', standard community treatment and other non-case management interventions. SEARCH METHODS We searched the following databases up to 31 December 2013: ALOIS, the Specialised Register of the Cochrane Dementia and Cognitive Improvement Group,The Cochrane Library, MEDLINE, EMBASE, PsycINFO, CINAHL, LILACS, Web of Science (including Science Citation Index Expanded (SCI-EXPANDED) and Social Science Citation Index), Campbell Collaboration/SORO database and the Specialised Register of the Cochrane Effective Practice and Organisation of Care Group. We updated this search in March 2014 but results have not yet been incorporated. SELECTION CRITERIA We include randomised controlled trials (RCTs) of case management interventions for people with dementia living in the community and their carers. We screened interventions to ensure that they focused on planning and co-ordination of care. DATA COLLECTION AND ANALYSIS We used standard methodological procedures as required by The Cochrane Collaboration. Two review authors independently extracted data and made 'Risk of bias' assessments using Cochrane criteria. For continuous outcomes, we used the mean difference (MD) or standardised mean difference (SMD) between groups along with its confidence interval (95% CI). We applied a fixed- or random-effects model as appropriate. For binary or dichotomous data, we generated the corresponding odds ratio (OR) with 95% CI. We assessed heterogeneity by the I² statistic. MAIN RESULTS We include 13 RCTs involving 9615 participants with dementia in the review. Case management interventions in studies varied. We found low to moderate overall risk of bias; 69% of studies were at high risk for performance bias.The case management group were significantly less likely to be institutionalised (admissions to residential or nursing homes) at six months (OR 0.82, 95% CI 0.69 to 0.98, n = 5741, 6 RCTs, I² = 0%, P = 0.02) and at 18 months (OR 0.25, 95% CI 0.10 to 0.61, n = 363, 4 RCTs, I² = 0%, P = 0.003). However, the effects at 10 - 12 months (OR 0.95, 95% CI 0.83 to 1.08, n = 5990, 9 RCTs, I² = 48%, P = 0.39) and 24 months (OR 1.03, 95% CI 0.52 to 2.03, n = 201, 2 RCTs, I² = 0%, P = 0.94) were uncertain. There was evidence from one trial of a reduction in the number of days per month in a residential home or hospital unit in the case management group at six months (MD -5.80, 95% CI -7.93 to -3.67, n = 88, 1 RCT, P < 0.0001) and at 12 months (MD -7.70, 95% CI -9.38 to -6.02, n = 88, 1 RCT, P < 0.0001). One trial reported the length of time until participants were institutionalised at 12 months and the effects were uncertain (hazard ratio (HR): 0.66, 95% CI 0.38 to 1.14, P = 0.14). There was no difference in the number of people admitted to hospital at six (4 RCTs, 439 participants), 12 (5 RCTs, 585 participants) and 18 months (5 RCTs, 613 participants). For mortality at 4 - 6, 12, 18 - 24 and 36 months, and for participants' or carers' quality of life at 4, 6, 12 and 18 months, there were no significant effects. There was some evidence of benefits in carer burden at six months (SMD -0.07, 95% CI -0.12 to -0.01, n = 4601, 4 RCTs, I² = 26%, P = 0.03) but the effects at 12 or 18 months were uncertain. Additionally, some evidence indicated case management was more effective at reducing behaviour disturbance at 18 months (SMD -0.35, 95% CI -0.63 to -0.07, n = 206, 2 RCTs I² = 0%, P = 0.01) but effects were uncertain at four (2 RCTs), six (4 RCTs) or 12 months (5 RCTs).The case management group showed a small significant improvement in carer depression at 18 months (SMD -0.08, 95% CI -0.16 to -0.01, n = 2888, 3 RCTs, I² = 0%, P = 0.03). Conversely, the case management group showed greater improvement in carer well-being in a single study at six months (MD -2.20 CI CI -4.14 to -0.26, n = 65, 1 RCT, P = 0.03) but the effects were uncertain at 12 or 18 months. There was some evidence that case management reduced the total cost of services at 12 months (SMD -0.07, 95% CI -0.12 to -0.02, n = 5276, 2 RCTs, P = 0.01) and incurred lower dollar expenditure for the total three years (MD= -705.00, 95% CI -1170.31 to -239.69, n = 5170, 1 RCT, P = 0.003). Data on a number of outcomes consistently indicated that the intervention group received significantly more community services. AUTHORS' CONCLUSIONS There is some evidence that case management is beneficial at improving some outcomes at certain time points, both in the person with dementia and in their carer. However, there was considerable heterogeneity between the interventions, outcomes measured and time points across the 13 included RCTs. There was some evidence from good-quality studies to suggest that admissions to care homes and overall healthcare costs are reduced in the medium term; however, the results at longer points of follow-up were uncertain. There was not enough evidence to clearly assess whether case management could delay institutionalisation in care homes. There were uncertain results in patient depression, functional abilities and cognition. Further work should be undertaken to investigate what components of case management are associated with improvement in outcomes. Increased consistency in measures of outcome would support future meta-analysis.

Abstract
BACKGROUND We examined emergency room (ER) utilization by persons with dementia (PWDs) using caregiver and patient characteristics as predictors. METHODS A secondary analysis of 296 veteran-caregiver dyads. Caregivers recorded PWD baseline characteristics and noted ER visits over the next year. Two sets of regression models analyzed categorical ER use and repeat ER use. RESULTS In the univariate analysis, categorical use of the ER was predicted by patients' functional status (P ≤ .008) and Veterans Affairs priority grouping (P ≤ .02). Repeat ER admissions were predicted by functional status (P ≤ .04), number of chronic conditions (P ≤ .01), and caregiver-reported relationship strain (P ≤ .04). In multivariate analysis, categorical ER use was predicted by functional status (P ≤ .02), priority grouping (P ≤ .03), and number of chronic conditions (P ≤ .06). CONCLUSIONS Functional status most strongly predicted ER use, highlighting the promise of home-based interventions to improve activities of daily living. Number of chronic conditions and caregiver-reported relationship strain are potential targets of intervention during discharge process.

Abstract
Aim. This paper reviews the theoretical and research-based literature related to the management of people with chronic confusion as a consequence of dementia in the acute care setting. Background. People aged 65 years and over are at increased risk of poor outcomes when admitted to the acute care setting as a result of comorbity and mismanagement of their chronic confusion. The challenge of caring for people with dementia in acute care is one that requires special attention. Results. The theoretical literature outlines a number of principles of care necessary for best practice in the care of people with dementia. A number of different models of care are reported in the literature and some evaluative research has been undertaken to assess the benefits of the different models. Conclusion. There are a number of interventions that if put into place in acute care may improve care of people with dementia and reduce the burden of care. There is emerging evidence that interventions such as staff education, skilled expertise, standardized care protocols and environmental modification help to meet the needs of people with dementia in acute hospital settings. This paper adds to our current understanding of management of dementia in the acute care setting, an area that demonstrates the need to move from descriptive to intervention studies to ensure evidence for care of persons with a dementing condition.

Abstract
BACKGROUND/RATIONALE Alzheimer's disease (AD) represents a serious public health issue affecting approximately 5.4 million individuals in the United States and is projected to affect up to 16 million by 2050. This study examined health care resource utilization (HCRU), costs, and comorbidity burden immediately preceding new diagnosis of AD and 2 years after diagnosis. METHODS This study utilized a claims-based, retrospective cohort design. Medicare Advantage members newly diagnosed with AD (n = 3374) were compared to matched non-AD controls (n = 6748). All patients with AD were required to have 12 months of continuous enrollment prior to AD diagnosis (International Classification of Diseases, Clinical Modification [ICD-9] 331.0), during which time no diagnosis of AD, a related dementia, or an AD medication was observed. Non-AD controls demonstrated no diagnosis of AD, a related dementia, or a prescription claim for an AD medication treatment during their health plan enrollment. Medical and pharmacy claims data were used to measure HCRU, costs, and comorbidity burden over a period of 36 months (12 months pre-diagnosis and 24 months post-diagnosis). RESULTS The HCRU and costs were greater for AD members during the year prior to diagnosis and during postdiagnosis years 1 and 2 compared to controls. The AD members also displayed greater comorbidity than their non-AD counterparts during postdiagnosis years 1 and 2, as measured by 2 different comorbidity indices. CONCLUSIONS Members newly diagnosed with AD demonstrated greater HCRU, health care costs, and comorbidity burden compared to matched non-AD controls.

Abstract
We performed a systematic review and meta-analysis to explore whether type 2 diabetes mellitus (T2DM) increases the risk of Alzheimer's disease (AD). We also reviewed interactions with smoking, hypertension, and apolipoprotein E ɛ4. Using a series of databases (MEDLINE, EMBASE, PubMed, Current Contents Connect, and Google Scholar), we identified a total of 15 epidemiologic studies. Fourteen studies reported positive associations, of which 9 were statistically significant. Risk estimates ranged from 0.83 to 2.45. The pooled adjusted risk ratio was 1.57 (95% confidence interval: 1.41, 1.75), with a population-attributable risk of 8%. Smoking and hypertension, when comorbid with T2DM, had odds of 14 and 3, respectively. Of the 5 studies that investigated the interaction between T2DM and apolipoprotein E ɛ4, 4 showed positive associations, of which 3 were significant, with odds ranging from 2.4 to 4.99. The pooled adjusted risk ratio was 2.91 (95% confidence interval: 1.51, 5.61). Risk estimates were presented in the context of a key confounder-cerebral infarcts-which are more common in those with T2DM and might contribute to the manifestation of clinical AD. We provide evidence from clinico-neuropathologic studies that demonstrates the following: First, cerebral infarcts are more common than AD-type pathology in those with T2DM and dementia. Second, those with dementia at postmortem are more likely to have both AD-type and cerebrovascular pathologies. Finally, cerebral infarcts reduce the number of AD lesions required for the manifestation of clinical dementia, but they do not appear to interact synergistically with AD-type pathology. Therefore, the increased risk of clinically diagnosed AD seems to be mediated through cerebrovascular pathology.

Abstract
BACKGROUND High levels of out-of-pocket (OOP) spending for health care may lead patients to forego needed services and medications as well as hamper their ability to pay for other essential goods. Because it leads to disability and the loss of independence, dementia may put patients and their families at risk for high OOP spending, especially for long-term care services. METHODS We used data from the Aging, Demographics, and Memory Study, a nationally representative subsample (n = 743) of the Health and Retirement Study, to determine whether individuals with dementia had higher self-reported OOP spending compared with those with cognitive impairment without dementia and those with normal cognitive function. We also examined the relationship between dementia and utilization of dental care and prescription medications-two types of health care that are frequently paid for OOP. Multivariate and logistic regression models were used to adjust for the influence of potential confounders. RESULTS After controlling for demographics and comorbidities, those with dementia had more than three times the yearly OOP spending compared with those with normal cognition ($8216 for those with dementia vs. $2570 for those with normal cognition, P < .01). Higher OOP spending for those with dementia was mainly driven by greater expenditures on nursing home care (P < .01). Dementia was not associated with the likelihood of visiting the dentist (P = .76) or foregoing prescription medications owing to cost (P = .34). CONCLUSIONS Dementia is associated with high levels of OOP spending but not with the use of dental care or foregoing prescription medications, suggesting that excess OOP spending among those with dementia does not "crowd out" spending on these other health care services.

Abstract
Objective: Estimating cost savings based on limited health care events within a short time span for a dementia care program. Method: Data on health care utilization of persons with dementia (PWDs) and caregivers were gathered in the Dementia Care Services Program in North Dakota from January 2010 to January 2012. Data were aggregated into 3-month intervals and compared to 3 months before program intervention. Paired and cross-time models were used to estimate cost savings. Results: Health care cost savings for PWDs were estimated at US$143,118 to US$180,102 during the first 3 months after intervention, then decreased over time. Only the first 9 months could be used in the paired model due to small N and low power. Discussion: For programs with short time spans and limited health care events, a cross-time model can be used to estimate cost savings while producing results similar to paired models.

Abstract
Prevalence of Alzheimer's disease (AD) will reach epidemic proportions in the United States and worldwide in the coming decades, and with substantially higher rates in African Americans (AAs) than in Whites. Older age, family history, low levels of education, and ɛ4 allele of the apolipoprotein E (APOE) gene are recognized risk factors for the neurodegeneration in AD and related disorders. In AAs, the contributions of APOE gene to AD risk continue to engender a considerable debate. In addition to the established role of cardiovascular disease (CVD) risk in vascular dementia, it is now believed that CVD risk and its endophenotype may directly comediate AD phenotype. Given the pleiotropic effects of APOE on CVD and AD risks, the higher rates of CVD risks in AAs than in Whites, it is likely that CVD risks contribute to the disproportionately higher rates of AD in AAs. Though the advantageous effects of aerobic exercise on cognition is increasingly recognized, this evidence is hardly definitive, and data on AAs is lacking. In this paper, we will discuss the roles of CVD risk factors in the development of AD and related dementias, the susceptibility of these risk factors to physiologic adaptation, and fitness-related improvements in cognitive function. Its relevance to AD prevention in AAs is emphasized.

Abstract
Objective To test the hypothesis that aerobic-related leisure-time physical activity (PA) is associated with better cognitive function and that the effect varies among apolipoprotein E (APOE) genotype groups. Design Cross-sectional study of persons examined in the Third National Health and Nutrition Examination Survey (NHANES-III; 1988–1994). Setting US noninstitutionalized population. Participants and methods From a sample of 7159, aged ≥60 years, we analyzed data for 1799 older American men and women who had information on PA, a short mental status examination (SMSE), and were genotyped at the apolipoprotein E gene locus. Results In the initial bivariate analysis, non-ɛ4 carriers and ɛ4-heterozygotes performed better than ɛ4-homozygotes in the 60–69 age group. After controlling for multiple confounders including mobility limitation, PA correlated with a higher SMSE score in non-ɛ4 carriers (P = 0.014), but not in ɛ4 carriers (P = 0.887). At ≥70 years, PA also correlated with higher adjusted SMSE scores in non-ɛ4 carriers (P = 0.02); but this association became nonsignificant after controlling for mobility limitation (P = 0.12). Conclusion In a nationally representative sample, PA was associated with enhanced cognition, an effect that was differentially influenced by apolipoprotein E genotype. Experimental studies are needed to determine whether or not PA can attenuate cognitive decline.

Abstract
CONTEXT Dementia is associated with increased rates and often poorer outcomes of hospitalization, including worsening cognitive status. New evidence is needed to determine whether some admissions of persons with dementia might be potentially preventable. OBJECTIVE To determine whether dementia onset is associated with higher rates of or different reasons for hospitalization, particularly for ambulatory care-sensitive conditions (ACSCs), for which proactive outpatient care might prevent the need for a hospital stay. DESIGN, SETTING, AND PARTICIPANTS Retrospective analysis of hospitalizations among 3019 participants in Adult Changes in Thought (ACT), a longitudinal cohort study of adults aged 65 years or older enrolled in an integrated health care system. All participants had no dementia at baseline and those who had a dementia diagnosis during biennial screening contributed nondementia hospitalizations until diagnosis. Automated data were used to identify all hospitalizations of all participants from time of enrollment in ACT until death, disenrollment from the health plan, or end of follow-up, whichever came first. The study period spanned February 1, 1994, to December 31, 2007. MAIN OUTCOME MEASURES Hospital admission rates for patients with and without dementia, for all causes, by type of admission, and for ACSCs. RESULTS Four hundred ninety-four individuals eventually developed dementia and 427 (86%) of these persons were admitted at least once; 2525 remained free of dementia and 1478 (59%) of those were admitted at least once. The unadjusted all-cause admission rate in the dementia group was 419 admissions per 1000 person-years vs 200 admissions per 1000 person-years in the dementia-free group. After adjustment for age, sex, and other potential confounders, the ratio of admission rates for all-cause admissions was 1.41 (95% confidence interval [CI], 1.23-1.61; P < .001), while for ACSCs, the adjusted ratio of admission rates was 1.78 (95% CI, 1.38-2.31; P < .001). Adjusted admission rates classified by body system were significantly higher in the dementia group for most categories. Adjusted admission rates for all types of ACSCs, including bacterial pneumonia, congestive heart failure, dehydration, duodenal ulcer, and urinary tract infection, were significantly higher among those with dementia. CONCLUSION Among our cohort aged 65 years or older, incident dementia was significantly associated with increased risk of hospitalization, including hospitalization for ACSCs.

Abstract
OBJECTIVES With the growing number of older adults, understanding expenditures associated with treating medical conditions that are more prevalent among older adults is increasingly important. The objectives of this research were to estimate incremental medical encounters and incremental Medicaid expenditures associated with dementia among Indiana Medicaid recipients 40 years or older in 2004. METHODS A retrospective cohort design analyzing Indiana Medicaid administrative claims files was used. Individuals at least 40 years of age with Indiana Medicaid eligibility during 2004 were included. Patients with dementia were identified via diagnosis codes in claims files between July 2001 and December 2004. Adjusted annual incremental medical encounters and expenditures associated with dementia in 2004 were estimated using negative binomial regression and zero-inflated negative binomial regression models. RESULTS A total of 18,950 individuals (13%) with dementia were identified from 145,684 who were 40 years or older. The unadjusted mean total annualized Medicaid expenditures for the cohort with dementia ($28,758) were significantly higher than the mean expenditures for the cohort without dementia ($14,609). After adjusting for covariates, Indiana Medicaid incurred annualized incremental expenditures of $9,829 per recipient with dementia. Much of the annual incremental expenditure associated with dementia was driven by the higher number of days in nursing homes and resulting nursing-home expenditures. Drug expenditures accounted for the second largest component of the incremental expenditures. On the basis of disease prevalence and per recipient annualized incremental expenditures, projected incremental annualized Indiana Medicaid spending associated with dementia for persons 40 or more years of age was $186 million. CONCLUSIONS Dementia is associated with significant expenditures among Medicaid recipients. Disease management initiatives designed to reduce nursing-home use among recipients with dementia may have much potential to decrease Medicaid expenditures associated with dementia.

Abstract
This paper investigates the coding of dementia in the episode of care in a pilot study group ( N=48) post hospital discharge and the possible implications of under-coding. The assigned ICD-10-AM codes and Diagnosis Related Groups were reviewed. Results demonstrate under-coding of dementia and of cognitive deficits; poor correlation between admission diagnoses and dementia codes on separation; and changes in individual patients' cognitive status across forms and assessments in the same admission. The complexities of accurately coding dementias will impact upon planning for future treatments and service provision and will have a flow-on effect for patients, hospitals, and patient care in Australia.

Abstract
A systematic review of dementia cost-of-illness (COI) studies in the US and Canada was conducted to explore the policy-making relevance of these studies. MEDLINE, CINAHL, EconLit, AMED and the Cochrane Library were searched from inception to March 2010 for English-language COI articles. Content analysis was used to extract common themes about dementia cost from the conclusions of articles that passed title, abstract and full-text screening. These themes informed our exploration of the policy-making relevance of COI studies in dementia. The literature search retrieved 961 articles and data were extracted from 46 articles. All except three articles reported data from the US; 27 articles included Alzheimer's dementia only. Common themes pertained to general observations about dementia cost, cost drivers in dementia, caregiver cost, items that may lower dementia cost, social service cost, Medicare and Medicaid cost, and cost comparisons with other diseases. The common themes suggest policy-oriented research for the future. However, the extracted COI studies were typically not conducted for policy-making purposes and they did not commonly provide prescriptive policy options. Researchers and policy makers need to consider whether the optimal research focus in dementia should be on programme evaluations instead of more COI studies.

Abstract
This study aimed to examine longitudinal patterns of VA-only use, dual VA and Medicare use, or Medicare-only use among veterans with dementia. Data on VA and Medicare use (1998-2001) were obtained from VA administrative datasets and Medicare claims for 2,137 male veterans with a formal diagnosis of Alzheimer's disease or vascular dementia enrolled in the National Longitudinal Caregiver Study. A random effects multinomial logit model accounting for unobserved individual heterogeneity was used to estimate the effects of patient and caregiver characteristics on use group over time. Compared to VA-only use, dual VA and Medicare use was associated with being white, married, higher education, having private insurance, Medicaid, low VA priority level, more functional limitations, and having lived in a nursing home or died in that year. Medicare-only use was associated with older age, being married, higher education, having private insurance, low VA priority level, living further from a VA Medical Center, having more comorbidities, functional limitations, and having lived in a nursing home or died. Veterans whose caregivers reported better health were more likely to be dual users, but those whose caregivers reported more comorbidities were more likely to use Medicare only. Different aspects of veterans' needs and caregiver characteristics have differential effect on where veterans seek care. Efforts to coordinate care between VA and Medicare providers are necessary to ensure patients receive high quality care.

Abstract
The objectives of this study were to examine longitudinal patterns of Department of Veterans Affairs (VA)-only use, dual VA and Medicare use, and Medicare-only use by veterans with dementia. Data on VA and Medicare use were obtained from VA administrative datasets and Medicare claims (1998-2001) for 2,137 male veterans who, in 1997, used some VA services, had a formal diagnosis of Alzheimer's disease or vascular dementia in the VA, and were aged 65 and older. Generalized ordered logit models were used to estimate the effects of patient characteristics on use group over time. In 1998, 41.7% of the sample were VA-only users, 55.4% were dual users, and 2.9% were Medicare-only users. By 2001, 30.4% were VA-only users, 51.5% were dual users, and 18.1% were Medicare-only users. Multivariate results show that greater likelihood of Medicare use was associated with older age, being white, being married, having higher education, having private insurance or Medicaid, having low VA priority level, and living in a nursing home or dying during the year. Higher comorbidities were associated with greater likelihood of dual use as opposed to any single system use. Alternatively, number of functional limitations was associated with greater likelihood of Medicare-only use and less likelihood of VA-only use. These results imply that different aspects of veterans' needs have differential effects on where they seek care. Efforts to coordinate care between VA and Medicare providers are necessary to ensure that patients receive high-quality care, especially patients with multiple comorbidities.

Abstract
The case-control approach has been a mainstay of epidemiological studies, particularly those investigating aetiology. Many articles addressing pharmacoeconomic topics have reported studies purported to be of the case-control type. However, on examination, these were actually standard cohort studies that were misnamed because they compared cases of a particular illness to 'controls' without the illness. The actual case-control design involves a series of cases with the outcome of interest. In pharmacoeconomic applications, the outcome of interest would typically be high cost, or hospitalization, or return to full quality of life. The illness does not define cases, but rather is actually the 'exposure'. The 'controls' must be a sample of the study base, not subjects without the illness. In this article, we review the features of a proper case-control study and contrast them with those of the more common cohort study. Confusing the control series of a cohort study with the 'controls' in a case-control study leads to serious problems with understanding the research, its strengths and drawbacks (e.g. confounding concerns), and interpretation of the findings. Although the case-control design has so far been used little to address pharmacoeconomic questions, it can be very efficient in certain situations, particularly when obtaining data on all subjects is burdensome or when conditions provide a ready case series but not the rest of the subjects.

Abstract
Families provide a considerable amount of informal care and support for older adults living with dementia. And when an older adult with dementia is hospitalized, family caregivers should be seen as important sources of information and included as valuable members of the health care team.

Abstract
The National Health Insurance database to determine the treated prevalence and incidence of dementia in Taiwan was used in this study. A population-based random sample of 22 118 subjects aged 65 or older was obtained as a dynamic cohort. Those study subjects who had filed at least one service claim from 1996 to 2003 for either outpatient care or inpatient care with a principal diagnosis of dementia were identified. The annual treated prevalence increased from 0.71% to 1.92% from 1996 to 2003. The annual treated incidence rates were around 0.76% to 1.04% per year from 1997 to 2003. The annual treated incidence rates for the 5-year age groups, from 65 to 90 years and older, were 0.44%, 0.65%, 0.98%, 1.46%, 1.81%, and 1.80%, respectively. Both the treated prevalence and incidence rates of dementia in National Health Insurance were lower than those of community studies.

Abstract
Background Alzheimer's disease (AD) is a neurodegenerative disorder incurring significant social and economic costs. This study uses a US administrative claims database to evaluate the effect of AD on direct healthcare costs and utilization, and to identify the most common reasons for AD patients' emergency room (ER) visits and inpatient admissions. Methods Demographically matched cohorts age 65 and over with comprehensive medical and pharmacy claims from the 2003–2004 MEDSTAT MarketScan® Medicare Supplemental and Coordination of Benefits (COB) Database were examined: 1) 25,109 individuals with an AD diagnosis or a filled prescription for an exclusively AD treatment; and 2) 75,327 matched controls. Illness burden for each person was measured using Diagnostic Cost Groups (DCGs), a comprehensive morbidity assessment system. Cost distributions and reasons for ER visits and inpatient admissions in 2004 were compared for both cohorts. Regression was used to quantify the marginal contribution of AD to health care costs and utilization, and the most common reasons for ER and inpatient admissions, using DCGs to control for overall illness burden. Results Compared with controls, the AD cohort had more co-morbid medical conditions, higher overall illness burden, and higher but less variable costs ($13,936 s. $10,369; Coefficient of variation = 181 vs. 324). Significant excess utilization was attributed to AD for inpatient services, pharmacy, ER visits, and home health care (all p < 0.05). In particular, AD patients were far more likely to be hospitalized for infections, pneumonia and falls (hip fracture, syncope, collapse). Conclusion Patients with AD have significantly more co-morbid medical conditions and higher healthcare costs and utilization than demographically-matched Medicare beneficiaries. Even after adjusting for differences in co-morbidity, AD patients incur excess ER visits and inpatient admissions.

Abstract
Dementia and delirium, the most common causes of cognitive impairment (CI) among hospitalized older adults, are associated with higher mortality rates, increased morbidity and higher health care costs. A growing body of science suggests that these older adults and their caregivers are particularly vulnerable to systems of care that either do not recognize or meet their needs. The consequences can be devastating for these older adults and add to the burden of hospital staff and caregivers, especially during the transition from hospital to home. Unfortunately, little evidence exists to guide optimal care of this patient group. Available research findings suggest that hospitalized cognitively impaired elders may benefit from interventions aimed at improving care management of both CI and co-morbid conditions but the exact nature and intensity of interventions needed are not known. This article will explore the need for improved transitional care for this vulnerable population and their caregivers.

Abstract
Alzheimer’s disease is a devastating chronic disease that significantly increases healthcare costs and affects the quality of life (QoL) of the afflicted patients and their caregivers. Population aging and other demographic changes may further increase the already staggering costs of this devastating disease. While few pharmacoeconomic studies have used a prospective health economics design to assess resource utilization, most studies showed beneficial treatment effects and suggested potential savings in healthcare costs and reductions in caregiver burden. Various degrees of cost savings have been reported depending on the type of economic model, treatment evaluated, and region used in the studies. Direct comparisons of the results are difficult because different methods have been used in these evaluations. The preference of patients and families for home care for as long as possible suggests that promoting noninstitutional care for these patients should become a priority. Continued home care for patients under pharmacological treatment may reduce caregiver burden, healthcare costs, and ultimately improve patients’ and caregivers’ QoL.

Abstract
OBJECTIVES This study estimated the prevalence of diagnosed dementia among Indiana Medicaid beneficiaries in 2004. The dependence of prevalence estimates upon use of several patient selection criteria to identify patients with dementia also was evaluated. METHODS Indiana Medicaid claims data were analyzed for the period July 1, 2002 to December 31, 2004. An expert panel survey was conducted to assess perceived specificity of ICD codes used in previous studies to define dementia. Prevalence estimates were calculated with varying levels of each selection criteria, that is, ICD code set, interval of data examined, and number of occurrences of dementia-related claims. To assess specificity and sensitivity of the dementia patient selection criteria, Minimum Data Set data for a subset of beneficiaries that resided in a nursing home any time in 2004 were examined. RESULTS Depending on the patient selection criteria used, estimates of prevalence of diagnosed dementia for individuals 40 years old or older varied from 7.7% to 15.3%, whereas prevalence estimates for individuals 60 years old or older varied from 14.5% to 26.6%. When the following selection criteria were used: (1) occurrence of one or more dementia-related claims, (2) the expert panel ICD set, and (3) up to 30 months of data for defining dementia, the prevalence estimates in the Indiana Medicaid population were 10.9% for individuals 40 years old or older and 20.3% for individuals 60 years old or older. CONCLUSIONS Careful selection of claims-based criteria for identifying patients with dementia is important because the criteria may affect estimates by 100%. Prevalence of diagnosed dementia among Indiana Medicaid beneficiaries was 3 to 4 times higher than the reported prevalence from a decade ago in Medicaid populations of other states, even when the same patient selection criteria were used. A number of factors beyond increased occurrence of the disease including increased screening, greater likelihood of recording dementia codes in claims, or other factors may be responsible. The combination of patient selection criteria used in this study had good sensitivity, specificity, and accuracy when compared with Minimum Data Set data.

Abstract
BACKGROUND Dementia is expected to become a significant social burden in the future. However, there are few reports that have estimated the total economic cost of dementia, particularly according to the limitation in the activities of daily living (ADL) in Korea. OBJECTIVES This study is to analyze the health care expenditures and cost per dementia patient, and estimated the total economic cost of dementia. METHODS Caregivers of 609 dementia patients, who were randomly selected from a nationwide claim database of the Korean National Health Insurance Corporation, were interviewed using structured questionnaire in the period of September 2005. The total cost including the direct and indirect costs during a year was calculated. The patients were stratified into three limitation groups according to their ADL score. The cost according to the three limitation groups was analyzed. The national cost of dementia patients was then estimated. RESULTS The total cost per dementia patient in Korea was $7,462. The direct and indirect costs were $6,626 and $836 per patient, respectively. The cost increased with increasing degree of limitation in the patient's ADL. Over a 1-year period, the total cost per patient in the low limitation group was lower ($3,698) than that of the moderate ($6,064) and high ($11,428) limitation group. CONCLUSIONS This study demonstrates that the direct and indirect costs of dementia are considerately small for patients with lower limitation in their ADL. The total economic cost of dementia per year was estimated to be in the range of 1.3 to 3.3 billion dollars on assumptions in Korea.

Abstract
Alzheimer’s dementia manifests in a complex clinical presentation that has been addressed from both biomedical and phenomenological perspectives. Although each of these paradigmatic perspectives has contributed to advancement of the science, neither is adequate for theoretically framing a person-centered approach to nursing care. The need-driven dementia-compromised behavior (NDB) model is discussed as an exemplar of midrange nursing theory that promotes the integration of these paradigmatic views to promote a new level of excellence in person-centered dementia care. Clinical application of the NDB promotes a new level of praxis, or thoughtful action, in the care of persons with dementia.

Abstract
Given the challenges and benefits of timely and accurate diagnosis of neurodegenerative disorders and the importance of appropriate subsequent treatments, physicians and patients alike desire tools that aid in diagnosing dementia as early and as precisely as possible. One of these tools may be functional brain imaging, specifically positron emission tomography (PET). Recent technological advancements, ongoing research studies, and approval for reimbursement by various insurance companies and Medicare, under certain circumstances, have led to an increased interest in the use of this tool in the evaluation of dementia. This article will review PET brain imaging in the initial assessment and diagnosis of dementia, including its place in current guidelines and role in diagnostic algorithms, its applicability in differentiating among various dementia syndromes and major psychiatric disorders, and some of the controversies surrounding its utility in general clinical practice.

Abstract
The objective of this study was to undertake a retrospective analysis of claims data of diabetic foot ulcer (DFU) patients to determine the rates of amputation and identify the risk and protective factors. Rates of amputation were calculated in patients diagnosed with DFU in the MEDSTAT Marketscan database between January 2000 and December 2002, who had prediagnosis coverage of 90 days. A nested case-control study was conducted using a 1 : 10 ratio of amputee cases to randomly selected nonamputee controls matched on follow-up days. The association of co-morbid conditions, demographic factors, and severity (5+ outpatient claims for DFU) on amputation was estimated by adjusted odds ratios (AOR) with 95% confidence intervals (CIs). The 5911 eligible patients yielded an incidence density rate of 2.30 amputations per 100 person years (95% CI = 1.91, 2.77). The 116 cases and 1153 controls averaged 307.3 and 308.5 observation days, respectively. Amputation was significantly increased by male gender (AOR 1.98), Charlson co-morbidity scores of 4-5 and 6+ (AOR = 2.89 and 5.36, respectively), renal disease (AOR = 2.11), peripheral vascular disease (AOR = 2.67), and 5+ outpatient DFU services (AOR = 2.17). Practitioners may consider more aggressive care and earlier referral to specialists for DFU patients who fit risk profiles for amputation, which include peripheral vascular disease, multiple co-morbid conditions, and repeated outpatient DFU services.

Abstract
OBJECTIVE The apolipoprotein E (ApoE) epsilon4 allele is a well-documented genetic risk factor for Alzheimer's disease (AD). Its role, if any, in the progression of cognitive and functional impairment in AD has been the subject of discrepant reports in the literature. This study aimed to determine whether ApoE epsilon4 dose is related to the progression of cognitive and functional decline in AD patients by combined retrospective and prospective analyses. METHODS A sample of 366 AD patients was genotyped for ApoE. Subjects received tests of cognition (Mini-Mental State Examination, MMSE; Alzheimer's Disease Assessment Scale-Cognitive subscale, ADAS-Cog) and daily function (Instrumental Activities of Daily Living, IADL; Alzheimer's Disease Cooperative Study-Activities of Daily Living, ADCS-ADL) at baseline and at multiple subsequent time points during their participation in a variety of research protocols. In retrospective analyses, scores on baseline cognitive and functional measures were compared cross-sectionally among genotype groups, controlling for duration of symptoms. In prospective analyses, longitudinal rates of change for each measure were computed by linear regression and compared across genotype groups. RESULTS No association was observed between ApoE epsilon4 dose and any of the retrospective or prospective measures of cognitive or functional decline in this AD patient sample. CONCLUSIONS Although ApoE epsilon4 increases the risk for AD and decreases the age of disease onset in population studies, it did not significantly influence the rate of disease progression in cognitive or functional domains in our sample.

Abstract
BACKGROUND Few studies on cost of caring for patients with Alzheimer disease (AD) have simultaneously considered multiple dimensions of disease costs and detailed clinical characteristics. OBJECTIVE To estimate empirically the incremental effects of patients' clinical characteristics on disease costs. METHODS Data are derived from the baseline visit of 180 patients in the Predictors Study, a large, multicenter cohort of patients with probable AD followed from early stages of the disease. All patients initially lived at home, in retirement homes, or in assisted living facilities. Costs of direct medical care included hospitalizations, outpatient treatment and procedures, assistive devices, and medications. Costs of direct nonmedical care included home health aides, respite care, and adult day care. Indirect costs were measured by caregiving time. Patients' clinical characteristics included cognitive status, functional capacity, psychotic symptoms, behavioral problems, depressive symptoms, extrapyramidal signs, comorbidities, and duration of illness. RESULTS A 1-point increase in the Blessed Dementia Rating Scale score was associated with a $1,411 increase in direct medical costs and a $2,718 increase in unpaid caregiving costs. Direct medical costs also were $3,777 higher among subjects with depressive symptoms than among those who were not depressed. CONCLUSIONS Medical care costs and unpaid caregiving costs relate differently to patients' clinical characteristics. Poorer functional status is associated with higher medical care costs and unpaid caregiving costs. Interventions may be particularly useful if targeted in the areas of basic and instrumental activities of daily living.

Abstract
BACKGROUND Alzheimer's disease (AD), the most common cause of dementia, is a major cause of disability and care burden in the elderly. This study aims to estimate the costs of formal and informal care and identity determinants of care costs. MATERIALS AND METHODS Two hundred and seventy-two (AD) patients and their caregivers were recruited among patients attending regular visits at six memory clinic in Sweden, Denmark, Norway and Finland. Patients with a diagnosis of AD and with an identifiable primary caregiver were eligible for inclusion. Data was collected by questionnaires at baseline, and at scheduled follow-up visits after 6 months and again after 12 months. Cognitive function was assessed with the Mini Mental State Examination (MMSE) and behavioural disturbances were measured using a brief version of the neuropsychiatric inventory (NPI). RESULTS Total annual costs were on average 172,000 SEK, ranging from 60,700 SEK in mild dementia to 375,000 SEK in severe dementia. Costs for community care (special accommodation, home help, etc.) constituted about half of total costs of care and increase sharply with increasing cognitive impairment. Informal care costs, valued at the opportunity cost of the caregiver's time, make up about a third of total costs and also increased significantly with disease severity. Medical care costs (inpatient care, outpatient care, pharmaceuticals), on the other hand, were not significantly related to disease severity. Regression analysis confirmed a strong association between costs and cognitive function, between patients as well as within patients over time. There was also a significant influence on costs from behavioural disturbances. Sensitivity analysis showed that the method chosen to value informal care can have considerable impact on results. CONCLUSIONS Costs of care in patient with AD are high and related to dementia severity as well as presence of behavioural disturbances. The cost estimates presented have implications for future economic evaluation of treatments for Alzheimer's disease.

Abstract
Given the intermittent use of special care units (SCUs), we consider economic aspects associated with dementia SCUs by reviewing the literature and surveying 2 nursing homes in the VA healthcare network. In addition to reporting the features in different types of facilities in the Veterans Affairs (VA), we present an economic characterization useful for hospital and nursing home administrators whose decision-making processes incorporate clinical, management, and financial factors. We conclude that, theoretically, benefits likely outweigh the costs of instituting dementia SCUs in VA nursing homes with a large number of cognitively impaired residents.

Abstract
PURPOSE Our objective in this study was to compare Medicare costs of treating older adults with and without dementia in nursing home settings. DESIGN AND METHODS An expert panel established the dementia status of a stratified random sample of newly admitted residents in 59 Maryland nursing homes between 1992 and 1995. Medicare expenditures per-person month (PPM) were compared for 640 residents diagnosed with dementia and 636 with no dementia for 1 year preadmission and 2 years postadmission. Multivariate analysis with generalized estimating equations was used to identify the source of Medicare cost differentials between the two groups. RESULTS Medicare expenditures peaked in the month immediately preceding admission and dropped to preadmission levels by the third month in a nursing home. Adjusted PPM costs postadmission for the dementia group as a whole were 79% (p < .001) of the Medicare costs of treating residents without dementia. For the subgroup of residents admitted without a Medicare qualified stay (MQS), those with dementia had Medicare costs of just 63% (p < .001) of those without dementia. Overall Medicare costs PPM were insignificantly different between the two groups admitted with a MQS. IMPLICATIONS Whether nursing home residents are admitted with a MQS is the single most important factor in assessing treatment cost differentials between residents admitted with and without dementia. Failure to consider this factor may lead researchers and policy makers to misdirect their attention from the true source of the differential-dementia patients admitted without a qualifying stay.
