Medicare expenditures among spouses of persons with dementia.

BACKGROUND: Spouses of persons living with dementia face intense strains on their well-being compared with similarly aged adults and spouses of partners with no dementia. This strain can impact spouses' health and healthcare needs, and therefore affect their healthcare utilization and expenditures. METHODS: Using data from the Health and Retirement Study linked with Medicare claims, we matched dyads of spouses and their partners with dementia (SPWD) to a comparison group of similar spouses and their partners with no dementia (SPWND). We then examined Medicare expenditures for spouses in the 5 years following their partner's dementia onset month using a two-part regression model. RESULTS: SPWD cumulative total Medicare expenditures were, on average, $60,043 in the 5 years post dementia onset, compared to $56,068 for SPWND. This difference ($3974, 95% CI = [-$3,199; $11,477]) was not significant. However, there were significant differences in the 5th year's total expenditures (+$2,748 [$321; $5,447]), driven by inpatient expenditures ($1,562 [$22; $3,277]). CONCLUSIONS: Despite the differences in partner's dementia status, we found no significant difference in the 5-year cumulative Medicare expenditures between SPWD and SPWND. Compared to previous studies, we likely captured an earlier stage of dementia more consistently for a broader population which may be less straining on spouses. Further research should examine patterns of expenditures in later years and around critical timepoints in caregiving, such as partner transitions to formal long-term care settings and death, to better understand healthcare expenditures for spouses of persons living with dementia.

Caregiving for dementia: trends pre-post onset and predictive factors of family caregiving (2002-2018).

Persons living with Alzheimer's and other related forms of dementia rely heavily on care from family and friends for assistance with daily activities ("family care"), but little is known about care transitions over time. We analyzed data from the Health and Retirement Study to describe caregiving patterns, from 2 years before dementia onset and up to 6 years after. Using sociodemographic data from the interview prior to dementia onset, we determined if there are significant factors that predict receipt of family care at dementia onset. We found that one-third (33%) of people living with dementia were receiving help with daily activities 2 years prior to their first positive dementia screen and this increased to 60% during the first positive screen. Nearly all of those receiving assistance received family care. We found multiple significant predictors of receiving family care at onset, including race, education, access to private health insurance, number of activities of daily living that were difficult, number of chronic conditions, and already receiving help. This demonstrates potential gaps in dementia care, and which subpopulations may benefit most from targeted interventions for household members who do not have adequate caregiving resources or programs that provide additional formal care.

Modeling the impact of financial hardship and age on self-rated health and depressive symptoms pre/post the great recession.

Stressful life events such as a recession, could be devastating on a macro and micro level. Although there have been a number of articles written examining the health effects of the recession, little is known about age differences in the relationship between financial stressors and health pre and post the 2008 recession. Using the Health and Retirement study, we investigated the relationship between two forms of financial hardships, mental and physical health among middle aged (N = 4403) and older adults) (N = 2709). Our findings indicate that with regard to financial hardships experienced pre/post recessionary periods there are differences by age. Specifically, older adults tend to report having less financial hardship than their younger counterparts. Additionally, reduced medication use due to costs was a significant predictor of poor self-rated health among middle aged participants compared to older adults. These results highlight the selective impact of recessions on certain age groups. They also suggests that economic recessions may also produce short-term procyclical health effects. Future research should focus on the relationship between other sources of financial hardship among middle-aged and older adults pre/post-recession at shorter time intervals.

Observational study of patient characteristics associated with a timely diagnosis of dementia and mild cognitive impairment without dementia.

BACKGROUND: Timely diagnosis of cognitive impairment is a key goal of the National Plan to Address Alzheimer's Disease, but studies of factors associated with a timely diagnosis are limited. OBJECTIVE: To identify patient characteristics associated with a timely diagnosis of dementia and mild cognitive impairment (MCI). DESIGN: Retrospective observational study using survey data from the Health and Retirement Study (HRS) from 1995-2016 (interview waves 3-13). PARTICIPANTS: 4,760 respondents with incident dementia and 1,864 with incident MCI identified using longitudinal measures of cognitive functioning. MAIN MEASURES: Timely or delayed diagnosis based on the timing of a self or proxy report of a healthcare provider diagnosis in relation to respondents first dementia or MCI-qualifying cognitive score, sociodemographic characteristics, health status, health care utilization, insurance provider, and year of first qualifying score. KEY RESULTS: Only 26.0% of the 4,760 respondents with incident dementia and 11.4% of the 1,864 respondents with incident MCI received a timely diagnosis. Non-Hispanic Black respondents and respondents with less than a college degree were significantly less likely to receive a timely diagnosis of either dementia or MCI than Non-Hispanic White respondents (dementia odds ratio (OR): 0.61, 95% CI: 0.50, 0.75; MCI OR: 0.40, 95% CI: 0.23, 0.70) and those with a college degree (dementia OR for less than high school degree: 0.30, 95% CI: 0.23, 0.38; MCI OR: 0.36, 95% CI: 0.22, 0.60). Respondents that lived alone were also less likely to receive a timely diagnosis of dementia (OR: 0.69, 95% CI: 0.59, 0.81), though not MCI. Timely diagnosis of both conditions increased over time. CONCLUSIONS: Targeting resources for timely diagnosis of cognitive impairment to individuals from racial and ethnic minorities, lower educational attainment, and living alone may improve detection and reduce disparities around timely diagnosis of dementia and MCI.

Statewide Evaluation of Washington's State Innovation Model Initiative: A Mixed-Methods Approach.

The Washington State Innovation Model (SIM) $65 million Test Award from the Center for Medicare and Medicaid Innovation is a statewide intervention expected to improve population health, quality of care, and cost growth through 4 initiatives in 2016-2018: (1) regional accountable communities of health linking health and social services to address local needs; (2) a practice transformation support hub; (3) four value-based payment reform pilot projects mainly in state employee and Medicaid populations; and (4) data and analytic infrastructure development to support system transformation with common measures. A mixed-methods study design and data from the 2013-2018 Behavioral Risk Factor Surveillance System Surveys are used to estimate whether SIM resulted in changes in access to care, health behaviors, and health status in Washington's adult population. Semi-structured qualitative interviews also were conducted to assess stakeholder perceptions of SIM performance. SIM may have reduced binge drinking, but no effects were detected for heavy drinking, physical activity, smoking, having a regular doctor checkup, unmet health care needs, and fair or poor health status. Complex interventions, such as SIM, may have unintended consequences. SIM was associated unexpectedly with increased unhealthy days, but whether the association was related to the Initiative or other factors is unclear. Over 3 years, stakeholders generally agreed that SIM was implemented successfully and increased Washington's readiness for system transformation but had not yet produced expected outcomes, partly because SIM had not spread statewide. Stakeholders perceived that scaling up SIM statewide takes time to achieve and remains challenging.

Family Medicine Resident Knowledge of Adverse Childhood Experiences.

INTRODUCTION: Exposure to adverse childhood experiences (ACEs) has been associated with poor health in adulthood. Primary care providers can provide more appropriate medical care and intervene if they ask patients about ACEs. The purpose of this study is to determine existing knowledge and attitudes about ACEs among family medicine residents within the Washington, Wyoming, Alaska, Montana, and Idaho (WWAMI) region. METHODS: Researchers developed a nine-question survey to assess family medicine residents' knowledge and attitudes about ACEs, and their comfort level in addressing ACEs. The survey was distributed to 540 residents in 22 family medicine residency programs in the WWAMI region. RESULTS: Most residents reported they had some (32%) or moderate (35%) knowledge of the ACEs study. However, 30% reported no knowledge of the ACEs study, and very few (3%) reported significant knowledge. Of 117 respondents reporting at least some prior knowledge of ACEs, 42% had first heard about ACEs during residency. The ACEs topics that respondents felt least comfortable addressing during a patient encounter were a patient's personal history of sexual abuse (75%) and witnessing physical abuse (47%). Most residents (84%) indicated that they would like to see ACEs integrated into their residency curriculum. DISCUSSION: This study demonstrates a gap in residency training on the topic of ACEs in family medicine residencies within the WWAMI region. Residents are uncomfortable addressing ACEs with patients but are receptive to learning about this topic. More teaching about ACEs can increase residents' comfort level with addressing these topics in the primary care setting.

The one-year impact of accountable care networks among Washington State employees.

OBJECTIVE: To estimate the impact of a new, two-sided risk model accountable care network (ACN) on Washington State employees and their families. DATA SOURCES/STUDY SETTING: Administrative data (January 2013-December 2016) on Washington State employees. STUDY DESIGN: We compared monthly health care utilization, health care intensity as measured through proxy pricing, and annual HEDIS quality metrics between the five intervention counties to 13 comparison counties, analyzed separately by age categories (ages 0-5, 6-18, 19-26, 18-64). DATA COLLECTION/EXTRACTION METHODS: We used difference-in-difference methods and generalized estimating equations to estimate the effects after 1 year of implementation for adults and children. PRINCIPAL FINDINGS: We estimate a 1-2 percentage point decrease in outpatient hospital visits due to the introduction of ACNs (adults: -1.8, P < .01; age 0-5: -1.2, P = .07; age 6-18: -1.2, P = .06; age 19-26; -1.2, P < .01). We find changes in primary and specialty care office visits; the direction of impact varies by age. Dependents age 19-26 were also responsive with inpatient admissions declines (-0.08 percentage points, P = .02). Despite changes in utilization, there was no evidence of changes in intensity of care and mixed results in the quality measures. CONCLUSIONS: Washington's state employee ACN introduction changed health care utilization patterns in the first year but was not as successful in improving quality.

Predictors and Outcomes of Patient Knowledge of Plan of Care in Hospital Medicine: A Quality Improvement Study.

BACKGROUND: Patient understanding of plan of care is associated with positive outcomes in ambulatory settings. In hospital medicine settings, patient-physician agreement on plan of care (concordance) has been limited and difficult to improve. This study examined the impact of adding a hospitalist to interdisciplinary rounds (IDR) on physician-patient-nurse concordance and the relationship between concordance and outcomes. METHODS: IDR were conducted by core teams made up of unit-based nurses, a case manager, and a pharmacist. Over time, with cohorting, hospitalists were included in IDR (hospitalist IDR) for some patients assigned to unit-based hospitalists. In developing hospitalist IDR, the researchers emphasized using an IDR checklist, including a patient communication plan. Patient-nurse-physician interviews were used to assess concordance in the domains of diagnosis, tests and procedures, and expected discharge date. Using two-hospitalist review, agreement was rated as none, partial, or complete, and a total concordance score was calculated for each patient in both IDR groups. Multivariate analysis was used to examine the relationship between concordance, IDR type, patient factors, and utilization outcomes. RESULTS: For 658 patients, the mean concordance score was 11.71 out of a possible 18. There was no difference in concordance between hospitalist and core IDR groups (11.68 vs. 11.84, p = 0.7). Higher total concordance score was associated with lower lengths of stay (p < 0.001) and readmission rates (p = 0.001). Total concordance had a negative association with patient age (p = 0.04). CONCLUSION: Concordance did not change with IDR type. Higher concordance appears to be related to positive utilization outcomes. Future studies are needed to evaluate potential interventions to improve concordance.

Health Care Costs of Alzheimer's and Related Dementias Within a Medicare Managed Care Provider.

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.

Cost of dementia in Medicare managed care: a systematic literature review.

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.

Assessing Occupancy and Its Relation to Healthcare-Associated Infections.

Occupancy has been associated with risk for healthcare-associated infections, yet its definition varies widely. Occupancy can be modeled as a function of census, acuity of the patient care unit, staffing ratio, or some combination. This article discusses the appropriate parameterization of these measures and how to interpret their impact. Infect Control Hosp Epidemiol 2016:1-3.

Reductions in High-End Imaging Utilization With Radiology Review and Consultation.

Following the uptake of value-based purchasing in concert with health care reform in the United States, providers, insurers, and patients are looking for ways to reduce excessive, dangerous, and/or inappropriate high-end imaging utilization (HEIU). Inappropriate HEIU is associated with patient safety risks due to unnecessary exposure to radiation, misappropriation of scarce equipment resources and staff, complications to clinical care, and needless, excessive costs for the patient, hospital, and payer. This paper presents a cost-effective radiology-initiated improvement program piloted in the Christiana Hospital Coordinated Care Network. The pilot demonstrated the effectiveness of regulating high-end imaging orders through radiologists' review of requests of the order as part of the consult process. Over the 2014-2015 fiscal year, 2,177 high-end imaging orders were reviewed by 26 radiologists for approval, rejection, or recommendation of an alternate examination. Of the orders, 86.7% (1887) were approved, 4.0% (87) were rejected, and 9.3% (203) received recommendation for an alternate examination. Based on improved patient safety, cost savings, and appropriate resource use, these findings suggest that radiologists' review can effectively reduce excessive HEIU. This method, with an appropriate algorithm to assist with handling a larger volume of orders, would be ideal to implement systemwide to manage HEIU cost efficiency, simultaneously providing radiologists with more control in their area of expertise and positively impacting quality, safety, and value-based purchasing goals.
