Changing home care aides: Differences between family and non-family care in California Medicaid home and community-based services.

In California Medicaid home-and-community-based services (HCBS), recipients' family members receive payment as home care aides (HCAs). We analyzed data on first-time HCBS recipients to examine factors associated with the likelihood of switching HCAs within the first year of services. Those with family HCAs were less than half as likely to change than those with non-family HCAs and racial/ethnic minorities with non-family HCAs had the highest switching rates. Lower wages and local unemployment were associated with switching of non-family HCAs but not family HCAs. Policymakers can foster continuity of home care by paying family members for home care and raising worker wages.

Predictors of Nursing Facility Entry by Medicaid-Only Older Adults and Persons With Disabilities in California.

Nearly one-third of adult Medicaid beneficiaries who receive long-term services and supports (LTSS) consist of older adults and persons with disabilities who are not eligible for Medicare. Beneficiaries, advocates, and policymakers have all sought to shift LTSS to home and community settings as an alternative to institutional care. We conducted a retrospective cohort study of Medicaid-only adults in California with new use of LTSS in 2006-2007 (N = 31 849) to identify unique predictors of entering nursing facilities versus receiving Medicaid home and community-based services (HCBS). Among new users, 18.3% entered into nursing facilities, whereas 81.7% initiated HCBS. In addition to chronic conditions, functional and cognitive limitations, substance abuse disorders (odds ratio [OR] 1.35; 95% confidence interval [CI]: 1.23, 1.48), and homelessness (OR: 4.35, 9% CI: 3.72, 5.08) were associated with higher odds of nursing facility entry. For older adults and persons with disabilities covered by Medicaid only, integration with housing and behavioral health services may be key to enabling beneficiaries to receive LTSS in noninstitutional settings.

Health Care Use Before and After Entering Long-Term Services and Supports.

OBJECTIVE: We examined the health care utilization patterns of Medicare and Medicaid enrollees (MMEs) before and after initiating long-term care in the community or after admission to a nursing facility (NF). METHOD: We used administrative data to compare hospitalizations, emergency department (ED) visits, and post-acute care use of MMEs receiving long-term care in California in 2006-2007. RESULTS: MMEs admitted to a NF for long-term care had much greater use of hospitalizations, ED visits, and post-acute care before initiating long-term care than those entering long-term care in the community. Post-entry, community service users had less than half the average monthly hospital and ED use compared with the NF cohort. CONCLUSION: Hospital and ED use prior to and following NF and personal care program entry suggest a need for reassessing the monitoring of these high-risk populations and the communication between health and community care providers.

Health Care Expenditures After Initiating Long-term Services and Supports in the Community Versus in a Nursing Facility.

BACKGROUND: Individuals who receive long-term services and supports (LTSS) are among the most costly participants in the Medicare and Medicaid programs. OBJECTIVES: To compare health care expenditures among users of Medicaid home and community-based services (HCBS) versus those using extended nursing facility care. RESEARCH DESIGN: Retrospective cohort analysis of California dually eligible adult Medicaid and Medicare beneficiaries who initiated Medicaid LTSS, identified as HCBS or extended nursing facility care, in 2006 or 2007. SUBJECTS: Propensity score matching for demographic, health, and functional characteristics resulted in a subsample of 34,660 users who initiated Medicaid HCBS versus extended nursing facility use. Those with developmental disabilities or in managed care plans were excluded. MEASURES: Average monthly adjusted acute, postacute, long-term, and total Medicare and Medicaid expenditures for the 12 months following initiation of either HCBS or extended nursing facility care. RESULTS: Those initiating extended nursing facility care had, on average, $2919 higher adjusted total health care expenditures per month compared with those who initiated HCBS. The difference was primarily attributable to spending on LTSS $2855. On average, the monthly LTSS expenditures were higher for Medicare $1501 and for Medicaid $1344 when LTSS was provided in a nursing facility rather than in the community. CONCLUSIONS: The higher cost of delivering LTSS in a nursing facility rather than in the community was not offset by lower acute and postacute spending. Medicare and Medicaid contribute similar amounts to the LTSS cost difference and both could benefit financially by redirecting care from institutions to the community.

Payment rates for personal care assistants and the use of long-term services and supports among those dually eligible for Medicare and Medicaid.

OBJECTIVE: To examine the association between payment rates for personal care assistants and use of long-term services and supports (LTSS) following hospital discharge among dual eligible Medicare and Medicaid beneficiaries. DATA SOURCES: State hospital discharge, Medicaid and Medicare claims, and assessment data on California Medicaid LTSS users from 2006 to 2008. STUDY DESIGN: Cross-sectional study. We used multinomial logistic regression to analyze county personal care assistant payment rates and postdischarge LTSS use, and estimate marginal probabilities of each outcome across the range of rates paid in California. DATA EXTRACTION METHODS: We identified dual eligible Medicare and Medicaid adult beneficiaries discharged from an acute care hospital with no hospitalizations or LTSS use in the preceding 12 months. PRINCIPAL FINDINGS: Personal care assistant payment rates were modestly associated with home and community-based services (HCBS) use versus nursing facility entry following hospital discharge (RRR 1.2, 95 percent CI: 1.0-1.4). For a rate of $6.75 per hour, the probability of HCBS use was 5.6 percent (95 percent CI: 4.2-7.1); at $11.75 per hour, 18.0 percent (95 percent CI: 12.5-23.4). Payment rate was not associated with the probability of nursing facility entry. CONCLUSIONS: Higher payment rates for personal care assistants may increase utilization of HCBS, but with limited substitution for nursing facility care.

The effects of cognitive impairment on nursing home residents' emergency department visits and hospitalizations.

BACKGROUND: Little is known about the relationship of cognitive impairment (CI) in nursing home (NH) residents and their use of emergency department (ED) and subsequent hospital services. METHODS: We analyzed 2006 Medicare claims and resident assessment data for 112,412 Medicare beneficiaries aged >65 years residing in US nursing facilities. We estimated the effect of resident characteristics and severity of CI on rates of total ED visits per year, then estimated the odds of hospitalization after ED evaluation. RESULTS: Mild CI predicted higher rates of ED visits relative to no CI, and ED visit rates decreased as severity of CI increased. In unadjusted models, mild CI and very severe CI predicted higher odds of hospitalization after ED evaluation; however, after adjusting for other factors, severity of CI was not significant. CONCLUSIONS: Higher rates of ED visits among those with mild CI may represent a unique marker in the presentation of acute illness and warrant further investigation.

Identifying at-risk dementia caregivers following institutionalization: the nursing home admission-burden and nursing home admission-depression prognostic tools.

The current study developed prognostic tools to identify dementia caregivers at-risk for clinically relevant burden or depressive symptoms following nursing home admission (NHA) of their family members. A retrospective, longitudinal design was used that included 1,610 dementia caregivers who provided data prior to and up to 6 months following nursing home admission. Response operant characteristic (ROC) curves were constructed to test and validate two prognostic tools: the NHA-Burden and NHA-Depression tools. An ROC curve yielded a sensitivity of 77% and a specificity of 62.5% at a cutoff score of 5.41 for the NHA-Burden Prognostic tool. A second ROC curve indicated a sensitivity of 75.4% and a specificity of 62.5% at a cutoff score of 7.45 for the NHA-Depression tool. Clinicians may wish to utilize cutpoints on the NHA-Burden and NHA-Depression tools to ensure that more persons who are at-risk for clinically significant burden or depression during NHA are identified.

Personal service assistance: musculoskeletal disorders and injuries in consumer-directed home care.

BACKGROUND: Like other types of care for disabled or elderly adults, consumer-directed personal assistance services may present multi-factorial risks for work-related musculoskeletal disorders (WRMSDs). METHODS: Using survey data, we compared providers experiencing WRMSDs in the previous year to those who did not, seeking to identify functional, temporal, physical, and relationship risk factors for transient and chronic conditions. RESULTS: Longer work experience with the recipient and more frequent bending increased the risk of being in the most chronic group (≥12 painful episodes), whereas predictable work hours with rest breaks and greater social support from the recipient appeared protective. For transient conditions (one to two episodes), longer work experience with the recipient and predictable hours with rest breaks appeared protective. CONCLUSIONS: We offer recommendations to improve hazard assessment as well as training and information distribution related to home care programs. With the population aging, home care jobs require increasing oversight to prevent WRMSDs.

In-home supportive services for individuals with cerebral palsy in California.

INTRODUCTION: Individuals with cerebral palsy (CP) may require personal assistance services for optimal functioning. The primary goal of this project is to determine if differences in health services exist between individuals with CP with family versus non-family member paid personal assistance providers. The secondary goal is to describe the population of children and non-elderly adults with CP receiving in-home supportive services (IHSS) and determine their health care costs compared to other IHSS recipients. METHODS: Administrative data from the California Departments of Health and Human Services, Social Services and Developmental Services were linked and de-identified to provide information about individuals receiving IHSS in California in 2005. Recipients with CP were characterized and compared by age. Then to determine the factors associated with hospital use and emergency room (ER) use for IHSS recipients with CP adjusted odds were calculated. Monthly expenditures were calculated from claims data. RESULTS: 2.3% of all IHSS recipients in 2005 had CP of which 46% were children. 59% of recipients with CP have a parent as their paid provider. The presence of other medical diagnoses was the only factor associated with increased adjusted odds of hospital and ER use for both child-aged and non-elderly adult recipients with CP. Functional limitations and provider type were not associated with increased odds of health care utilization. Monthly health care expenditures for recipients with CP were ∼$1000 higher than for other IHSS recipients. CONCLUSIONS: Having a parent as the IHSS provider was not associated with difference in health service utilization. This finding supports the policy of allowing parents to be paid providers.

Allowing spouses to be paid personal care providers: spouse availability and effects on Medicaid-funded service use and expenditures.

PURPOSE OF THE STUDY: Medicaid service use and expenditure and quality of care outcomes in California's personal care program known as In-Home Supportive Service (IHSS) are described. Analyses investigated Medicaid expenditures, hospital use, and nursing home stays, comparing recipients who have paid spouse caregivers with those having other relatives or unrelated individuals as their caregivers. DESIGN AND METHODS: Medicaid claims and IHSS assessment data for calendar year 2005 were linked for IHSS recipients aged 18 years or older (n = 386,447) RESULTS: The rates of ambulatory care-sensitive hospital admissions and Medicaid-covered nursing home placements were at least comparable among IHSS recipients' with spouse, parent, other relative, or nonrelative caregivers. Statistically significant differences reflected more desirable outcomes for those with relatives as paid caregivers. In no comparisons did those with spouse providers have worse outcomes than those with nonrelative providers. Average monthly Medicaid expenditures for all services were also lower for IHSS recipients with family provider. IMPLICATIONS: There were no financial disadvantages and some advantages to Medicaid in terms of lower average Medicaid expenditures and fewer nursing home admissions when using spouses, parents, and other relatives as paid IHSS providers. This argues in favor of honoring the recipient's and family's preference for such providers.

Emergency department use by nursing home residents: effect of severity of cognitive impairment.

PURPOSE: To examine the 1-year prevalence and risk of emergency department (ED) use and ambulatory care-sensitive (ACS) ED use by nursing home (NH) residents with different levels of severity of cognitive impairment (CI). DESIGN AND METHODS: We used multinomial logistic regression to estimate the effect of CI severity on the odds of any ED visit and any ACS ED visit in a 2006 national random sample of NH residents, controlling for predisposing, enabling, and need characteristics. RESULTS: Of 132,753 NH residents, 62% had at least one ED visit and approximately 24% had at least one ACS ED visit in 2006. The probability of any ED visit or any ACS ED visit varied with the severity of resident CI. Residents with mild CI had up to 15% higher odds of any ED or any ACS ED visit and those with more moderate CI had 9% higher odds of an ACS ED visit compared with those without CI. The probability of any ED visit was negatively associated with advanced dementia (adjusted odds ratio = 0.60; 95% CI = 0.55-0.65). IMPLICATIONS: Earlier identification of persons with mild CI may facilitate patient, family, and staff education, as well as advanced care planning to reduce ACS ED visits. Both ACS ED use and hospitalizations, adjusted for case mix, should be used as quality indicators to help ensure greater accountability for high-quality NH care and more appropriate utilization of ED resources.

High rate of unemployment after liver transplantation: analysis of the United Network for Organ Sharing database.

The goal of liver transplantation (LT) is to maximize the length and quality of a patient's life and facilitate his or her return to full productivity. The aims of this study were (1) to use the United Network for Organ Sharing (UNOS) data set to determine the proportions of recipients who were employed and unemployed within 24 months after LT between 2002 and 2008 and (2) to examine the factors associated with a return to employment. UNOS data that were collected since the adoption of the Model for End-Stage Liver Disease scoring system on February 27, 2002 were analyzed. There were 21,942 transplant recipients who met the inclusion criteria. The employment status of the recipients was analyzed within a 60-day window at the following times after transplantation: 6, 12, and 24 months. Approximately one-quarter of the LT recipients (5360 or 24.4%) were employed within 24 months after transplantation, and the remaining recipients had not returned to work. The demographic variables that were independently associated with posttransplant employment included an age of 18 to 40 years, male sex, a college degree, Caucasian race, and pretransplant employment. Patients with alcoholic liver disease had a significantly lower rate of employment than patients with other etiologies of liver disease. The recipients who were employed after transplantation had significantly better functional status than those who were not employed. In conclusion, the employment rate after LT is low, with only one-quarter of LT recipients employed. New national and individual transplant program policies are needed to assess the root causes of unemployment in recipients who wish to work after LT.

Consumer-directed personal care: comparing aged and non-aged adult recipient health-related outcomes among those with paid family versus non-relative providers.

Risk factors associated with the incidence of recipient injuries, bedsores and contractures, and health care use (i.e., emergency department and hospital use) among aged and non-aged adult personal care recipients are investigated. Data are from a statewide survey of aged and non-aged adult personal assistance service (PAS) recipients (n = 913) in California's In-Home Supportive Services (IHSS) program. This is a consumer-directed PAS program. Outcomes among recipients using relatives (other than spouses or parents) as paid providers are compared with those of recipients having non-relatives as providers. No differences were found by provider-recipient relationships. Non-aged recipients, those in poorer health, those with more than three activities of daily living (ADL) limitations, and those changing providers during the year were all at greater risk for adverse health outcomes. African American, Hispanic, and Asian recipients were at lower risk for injuries and hospital stays than were White recipients.

Does caregiver burden mediate the effects of behavioral disturbances on nursing home admission?

OBJECTIVES: The primary objective of this study was to determine whether caregiving burden mediated the relationship between specific behavior disturbances and time to nursing home admission (NHA) for persons with dementia (i.e., Alzheimer disease or a related disorder). DESIGN: The study used secondary longitudinal data from the Medicare Alzheimer's Disease Demonstration, a Medicare-covered home care benefit and case management program for family caregivers of persons with dementia. Primary caregivers of persons with dementia were assessed via in-person and telephone interviews every 6 months over a 3-year period. SETTING: Dementia caregivers were recruited from eight catchment areas throughout the United States. PARTICIPANTS: The baseline sample included 5,831 dementia caregivers. Just more than 40% (43.9%; N = 2,556) of persons with dementia permanently entered a nursing home during the 3-year study period. MEASUREMENTS: Individual behavior problems were measured with the Memory and Behavior Problem Checklist. Caregiving burden was assessed with a short version of the Zarit Burden Inventory. Key covariates, including sociodemographic background, functional status, and service utilization, were also considered. RESULTS: Event history analyses revealed that time-varying measures of caregiver burden fully mediated the relationship between four behavioral disturbances (episodes of combativeness, property destruction, repetitive questions, and reliving the past) and NHA. CONCLUSIONS: The findings highlight the multifaceted, complex pathway to NHA for persons with dementia and their family caregivers. The results emphasize the need for comprehensive treatment approaches that incorporate the burden of caregivers and the behavioral/psychiatric symptoms of persons with dementia simultaneously.

Human coronary artery smooth muscle cell responses to bioactive polyelectrolyte multilayer interfaces.

Under normal physiological conditions, mature human coronary artery smooth muscle cells (hCASMCs) exhibit a "contractile" phenotype marked by low rates of proliferation and protein synthesis, but these cells possess the remarkable ability to dedifferentiate into a "synthetic" phenotype when stimulated by conditions of pathologic stress. A variety of polyelectrolyte multilayer (PEMU) films are shown here to exhibit bioactive properties that induce distinct responses from cultured hCASMCs. Surfaces terminated with Nafion or poly(styrenesulfonic acid) (PSS) induce changes in the expression and organization of intracellular proteins, while a hydrophilic, zwitterionic copolymer of acrylic acid and 3-[2-(acrylamido)-ethyl dimethylammonio] propane sulfonate (PAA-co-PAEDAPS) is resistant to cell attachment and suppresses the formation of key cytoskeletal components. Differential expression of heat shock protein 90 and actin is observed, in terms of both their magnitude and cellular localization, and distinct cytoplasmic patterns of vimentin are seen. The ionophore A23187 induces contraction in confluent hCASMC cultures on Nafion-terminated surfaces. These results demonstrate that PEMU coatings exert direct effects on the cytoskeletal organization of attaching hCASMCs, impeding growth in some cases, inducing changes consistent with phenotypic modulation in others, and suggesting potential utility for PEMU surfaces as a coating for coronary artery stents and other implantable medical devices.

Clinically significant changes in burden and depression among dementia caregivers following nursing home admission.

BACKGROUND: Although extensive research exists on informal long-term care, little work has examined the clinical significance of transitions in family caregiving due to a lack of established clinical cut-points on key measures. The objectives of this study were to determine whether clinically significant changes in symptoms of burden and depression occur among caregivers within 12 months of nursing home admission (NHA) of their relatives with dementia, and to identify key predictors of clinically persistent burden and depression in the first year after institutionalization. METHODS: Secondary longitudinal analysis of dementia caregivers were recruited from eight catchment areas in the United States with 6- and 12-month post-placement follow-up data. The sample included data on 1,610 dementia caregivers with pre- and six-month post-placement data and 1,116 with pre-placement, six-month, and 12-month post-placement data. Burden was measured with a modified version of the Zarit Burden Inventory. Depressive symptoms were assessed with the Geriatric Depression Scale. RESULTS: Chi-square analyses found significant (P < .05) reductions in the number of caregivers who reported clinically significant burden and depressive symptoms after NHA compared to pre-placement. Logistic regression models revealed that wives and daughters were most likely to experience clinically persistent burden and husbands were most likely to experience clinically significant depression after NHA. CONCLUSIONS: In addition to suggesting that clinically significant decreases in caregiver burden and depression are likely to occur following institutionalization, the results reveal particular subsets of caregivers who are at continued risk of distress. Such findings can facilitate development of screening processes to identify families at-risk following institutionalization.

Do trajectories of at-home dementia caregiving account for burden after nursing home placement? A growth curve analysis.

Transitioning to the nursing home setting is a complex process for family caregivers of older adults with dementia. While nursing home placement (NHP) can alleviate certain caregiving responsibilities, new stressors can also emerge. In the present study, the researchers examined how care-related factors can change leading up to NHP and how these factors influence caregiver outcomes following NHP. A sample of 634 family dementia caregivers (n = 634) were surveyed at three six-month intervals prior to NHP and once during the 12 month period following institutionalization. Growth curve modeling revealed dynamic changes in certain factors leading up to NHP (e.g., caregivers' perceived health), while other factors remained stable (e.g., caregiver burden). Several factors emerged as significant predictors of caregiver burden following NHP, including pre-placement burden and adult day service utilization. For geriatric social workers, these findings may be useful in assessing family caregivers, and in the development and utilization of appropriate interventions.

The effects of incident and persistent behavioral problems on change in caregiver burden and nursing home admission of persons with dementia.

BACKGROUND: The individual contributions of behavior problems to key and related outcomes in dementia, such as nursing home admission (NHA) or caregiver burden, remain unclear. OBJECTIVES: This study sought to determine the ramifications of temporal change in individual behavior problems when accounting for increases in caregiver burden and time to NHA. Although burden is sometimes conceptualized as an antecedent to NHA, it has also emerged as a relevant outcome in dementia caregiving research. METHODS: A sample of 4545 dementia caregivers who participated in the Medicare Alzheimer disease Demonstration Evaluation was selected for this secondary analysis. Various patterns of change in individual behavior problems were considered as predictors of increases in caregiver burden and time to NHA over a 3-year period via mixed effects and Cox proportional hazards models, respectively. RESULTS: Caregivers who did not indicate a care recipient's dangerous behavior initially but did so subsequently (ie, an "incident" behavior problem) were more likely to experience increases in burden (P < 0.0026). Alternatively, the persistent occurrence of behavior disturbances (particularly memory problems) emerged as the strongest predictors of time to NHA. DISCUSSION: The findings of this study suggest the benefit of examining temporal patterns of individual behavioral disturbances, and that incident and persistent problems account for different dementia outcomes over time. Considering the temporal ramifications and potency of specific behavior problems can facilitate the targeted and timely delivery of effective clinical interventions.

Alteration in protein expression in estrogen receptor alpha-negative human breast cancer tissues indicates a malignant and metastatic phenotype.

Ductal carcinoma in situ (DCIS) represents the earliest identifiable breast cancer lesion. Disruption of the myoepithelial cell layer and basement membrane is a prerequisite for DCIS to initiate invasion into the stroma. The majority of epithelial cells overlying a focally-disrupted myoepithelial cell layer are estrogen receptor-alpha negative (ER(-)); however, adjacent cells within the same duct confined by an intact myoepithelial cell layer express high levels of ER. These ER (+) and ER (-) cells were microdissected from the same ducts of breast cancer patients. Differential proteins expressed by ER(+) and ER(-) cells were identified using two-dimensional gel electrophoresis followed by mass spectrometry and Western blot analysis. ER(-) cells express lower levels of superoxide dismutase, RalA binding protein, galectin-1, uridine phosphorylase 2, cellular retinoic acid-binding protein 1, S100 calcium binding protein A11, and nucleoside diphosphate kinase A or non-metastasis protein 23-H1 (nm23-H1). The upregulated protein, Rho GDP-dissociation inhibitor 1 alpha, may induce chemotherapy resistance. The significant findings are that the microdissected ER(-) cells express 12.6 times less cellular retinoic acid-binding protein 1, a protein involved in cellular differentiation, and 4.1 times less nucleoside diphosphate kinase A or nm23-H1, a metastasis suppressor, and express fewer proteins than adjacent ER(+) cells. The collective role of the alterations of protein expression in ER(-) cells may be to promote a more malignant phenotype than adjacent ER(+) cells, including a decreased ability to undergo apoptosis and differentiation, and an increased potential to damage DNA, metastasize, and resist to chemotherapy.
