Relationship between state medicaid policies, nursing home racial composition, and the risk of hospitalization for black and white residents

Sociodemographic Disparities in the Use of Hospice by U.S. Nursing Home Residents: A Systematic Review

Hospice can improve end-of-life (EOL) outcomes in U.S. nursing homes (NHs). However, only one-third of eligible residents enroll, and substantial variation exists within and across NHs related to resident-, NH-, or community-level factors. We conducted a review of English-language, peer-reviewed articles 2008 to 2023 describing this variation in NH hospice use to characterize disparities and inform educational and quality initiatives to improve EOL care in NHs. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We screened 1595 records, reviewed 82 articles and included 13 articles. Eleven used pre-2009 data. Six evaluated national data and 7 used regional (n = 1), state (n = 4), or local (n = 2) data. One assessed hospice referral, 10 hospice use, and 3 length-of-stay. Twelve conducted regression analyses; 1 stratified by race, another evaluated interaction terms, and a third compared racial differences within-and between-facilities. Unadjusted and adjusted differences were evaluated by resident race-and-ethnicity (n = 6 unadjusted, n = 10 adjusted, respectively), sex (n = 5, n = 9), or payor (n = 1, n = 4), or by NH race-mix (n = 1, n = 2), ownership (n = 1, n = 7), payor-mix (n = 1, n = 5), or urban/rural location (n = 1 adjusted). Unadjusted differences showed lower hospice use by Non-White residents and varied results by sex. Studies adjusting for resident-, NH-, and community-level factors found lower hospice use among male residents, Black/Non-White residents, and residents of rural NHs, with mixed results by payor and ownership. Results were mixed for hospice referral and length-of-stay. These findings suggest complex influences on NH hospice use. Further study is warranted to identify targets for improving hospice access.

Impact of Extreme Weather Events on Health Outcomes of Nursing Home Residents Receiving Post-Acute Care and Long-Term Care: A Scoping Review

OBJECTIVES

To systematically examine the evidence of the association between extreme weather events (EWEs) and adverse health outcomes among short-stay patients undergoing post-acute care (PAC) and long-stay residents in nursing homes (NHs).

DESIGN

This is a scoping review. The findings were reported using the Preferred Reporting Items for Systematic Review and Meta-Analysis Extension for Scoping Reviews checklist.

SETTINGS AND PARTICIPANTS

Studies published on short-stay PAC and long-stay residents in NHs.

METHODS

A literature search was performed in 6 databases. Studies retrieved were screened for eligibility against predefined inclusion and exclusion criteria. Studies were qualitatively synthesized based on the EWE, health outcomes, and special populations studied.

RESULTS

Of the 5044 studies reviewed, 10 met our inclusion criteria. All were retrospective cohort studies. Nine studies examined the association between hurricane exposure, defined inconsistently across studies, and PAC patients and long-stay residents in the NH setting in the Southern United States; the other study focused on post-flood risk among North Dakota NH residents. Nine studies focused on long-stay NH residents receiving custodial care, and 1 focused on patients receiving PAC. Outcomes examined were unplanned hospitalization rates and mortality rates within 30 and 90 days and changes in cognitive impairment. Nine studies consistently found an association between hurricane exposure and increased risk of 30- and 90-day mortality compared to unexposed residents.

CONCLUSIONS AND IMPLICATIONS

Of the EWEs examined, hurricanes are associated with an increased risk of mortality among long-stay NH residents and those admitted to hospice, and with increased risk of hospitalization for short-stay PAC patients. As the threat of climate-amplified EWEs increases, future studies of NH residents should evaluate the impact of all types of EWEs, and not solely hurricanes, across wider geographic regions, and include longer-term health outcomes, associated costs, and analyses of potential disparities associated with vulnerable populations in NHs.

Addressing Systemic Racism in Nursing Homes: A Time for Action

Long-term services and supports for older persons in the United States are provided in a complex, racially segregated system, with striking racial disparities in access, process, and outcomes of care for residents, which have been magnified during the Coronavirus Disease 2019 pandemic. These disparities are in large measure the result of longstanding patterns of structural, interpersonal, and cultural racism in US society, which in aggregate represent an underpinning of systemic racism that permeates the long-term care system's organization, administration, regulations, and human services. Mechanisms underlying the role of systemic racism in producing the observed disparities are numerous. Long-term care is fundamentally tied to geography, thereby reflecting disparities associated with residential segregation. Additional foundational drivers include a fragmented payment system that advantages persons with financial resources, and reimbursement policies that systematically undervalue long-term care workers. Eliminating disparities in health outcomes in these settings will therefore require a comprehensive approach to eliminating the role of systemic racism in promoting racial disparities.

Cancer Pain in Relation to Metropolitan Area Segregation and Nursing Home Racial and Ethnic Composition

OBJECTIVES

To estimate pain reporting among residents with cancer in relation to metropolitan area segregation and NH racial and ethnic composition.

DESIGN

Cross-sectional study.

SETTING AND PARTICIPANTS

383,757 newly admitted black (B), Hispanic (H), or white (W) residents with cancer in 12,096 US NHs (2011-2013).

METHODS

Using the Minimum Data Set 3.0, pain in past 5 days was determined by self-report or use of pain management. The Theil entropy index, a measure of metropolitan area segregation, was categorized [high (up to 0.20), very high (0.20-0.30), or extreme (0.30-0.53)].

RESULTS

Pain prevalence decreased across segregation level (black: high = 77%, very high = 75%, extreme = 72%; Hispanic: high = 79%, very high = 77%, extreme = 70%; white: high = 80%, very high = 77%, extreme = 74%). In extremely segregated areas, all residents were less likely to have recorded pain [adjusted prevalence ratios: blacks, 4.6% less likely, 95% confidence interval (CI) 3.1%-6.1%; Hispanics, 6.9% less likely, 95% CI 4.2%-9.6%; whites, 7.4% less likely, 95% CI 6.5%-8.2%] than in the least segregated areas. At all segregation levels, pain was recorded more frequently for residents (black or white) in predominantly white (>80%) NHs than in mostly black (>50%) NHs or residents (Hispanic or white) in predominantly white NHs than mostly Hispanic (>50%) NHs.

CONCLUSIONS AND IMPLICATIONS

We observed decreased pain recording in metropolitan areas with greater racial and ethnic segregation. This may occur through the inequitable distribution of resources between NHs, resident-provider empathy, provider implicit bias, resident trust, and other factors.

Health Outcomes of Immigrants in Nursing Homes: A Population-Based Retrospective Cohort Study in Ontario, Canada

OBJECTIVE

Older adults account for a significant portion of Canadian immigrants, yet characteristics and health outcomes of older immigrants in nursing homes have not been studied. We aimed to describe the prevalence of immigrants living in nursing homes, their characteristics, and their hospitalization and mortality rates compared to long-term residents in the first year of entry to nursing homes.

DESIGN

Population-based, retrospective cohort study using linked health administrative databases.

SETTING AND PARTICIPANTS

We assessed all incident admissions into publicly funded nursing homes in Ontario between April 2013 and March 2016. Immigrants were defined as those who arrived in Canada after 1985; long-term residents are those who arrived before 1985 or are Canadian-born.

METHODS

The primary outcome was all-cause hospitalization and mortality rates within 1 year of nursing home entry. Nested Cox proportional hazards models were estimated to explore the associations of facility, demographic, and clinical characteristics to the primary outcomes.

RESULTS

Immigrants comprised 4.4% of residents in Ontario's nursing homes, compared to 13.9% in the general population. The majority were from East and Southeast Asia (52.2%), and more than half (53.9%) had no competency in either official language on arrival in Canada. At the time of nursing home entry, immigrants were younger than long-term residents but had greater functional and cognitive impairments. Immigrants had a lower rate of mortality [hazard ratio 0.58, 95% confidence interval (CI) 0.51, 0.68; P < .001] but were more likely to be hospitalized (hazard ratio 1.14, 95% CI 1.06, 1.23; P < .001). Adjusting for language ability, the effect of immigrant status on hospitalization was not statistically significant.

CONCLUSIONS AND IMPLICATIONS

Despite greater functional and cognitive impairments, immigrants in nursing homes had lower mortality than long-term residents, potentially reflecting the "healthy immigrant effect." Inability to speak English was associated with increased risk of hospitalization, highlighting the need for strategies to overcome communication barriers.

Racial Segregation Across U.S. Nursing Homes: A Systematic Review of Measurement and Outcomes

BACKGROUND AND OBJECTIVES

Nursing homes remain subjected to institutional racial segregation in the United States. However, a standardized approach to measure segregation in nursing homes does not appear to be established. A systematic review was conducted to identify all formal measurement approaches to evaluate racial segregation among nursing home facilities, and to then identify the association between segregation and quality of care in this context.

RESEARCH DESIGN AND METHODS

PubMed, Scopus, and Web of Science databases were searched (January 2018) for publications relating to nursing home segregation. Following the PRISMA guidelines, studies were included that formally measured racial segregation of nursing homes residents across facilities with regional-level data.

RESULTS

Eight studies met the inclusion criteria. Formal segregation measures included the Dissimilarity Index, Disparities Quality Index, Modified Thiel's Entropy Index, Gini coefficient, and adapted models. The most common data sources were the Minimum Data Set (MDS; resident-level), the Certification and Survey Provider Enhanced Reporting data (CASPER; facility-level), and the Area Resource File/ U.S. Census Data (regional-level). Most studies showed evidence of racial segregation among U.S. nursing home facilities and documented a negative impact of segregation on racial minorities and facility-level quality outcomes.

DISCUSSION AND IMPLICATIONS

The measurement of racial segregation among nursing homes is heterogeneous. While there are limitations to each methodology, this review can be used as a reference when trying to determine the best approach to measure racial segregation in future studies. Moreover, racial segregation among nursing homes remains a problem and should be further evaluated.

Inappropriate Antipsychotic Use: The Impact of Nursing Home Socioeconomic and Racial Composition

OBJECTIVES

Previous research suggests black nursing home (NH) residents are more likely to receive inappropriate antipsychotics. Our aim was to examine how NH characteristics, particularly the racial and socioeconomic composition of residents, are associated with the inappropriate use of antipsychotics.

DESIGN

This study used a longitudinal approach to examine national data from Long-Term Care: Facts on Care in the US (LTCFocUS.org) between 2000 and 2015. We used a multivariate linear regression model with year and state fixed effects to estimate the prevalence of inappropriate antipsychotic use at the NH level.

SETTING

Free-standing NHs in the United States.

PARTICIPANTS

The sample consisted of 12 964 NHs.

MEASUREMENTS

The outcome variable was inappropriate antipsychotic use at the facility level. The primary indicator variables were whether a facility had high proportions of black residents and the percentage of residents with Medicaid as their primary payer.

RESULTS

NHs with high and low proportions of blacks had similar rates of antipsychotic use in the unadjusted analyses. NHs with high proportions of black residents had significantly lower rates of inappropriate antipsychotic use (β = -2; P < .001) in the adjusted analyses. Facilities with high proportions of Medicaid-reliant residents had higher proportions of inappropriate use (β = .04; P < .001).

CONCLUSION

Findings from this study indicate a decline in the use of antipsychotics. Although findings from this study indicated facilities with higher proportions of blacks had lower inappropriate antipsychotic use, facility-level socioeconomic disparities continued to persist among NHs. Policy interventions that focus on reimbursement need to be considered to promote reductions in antipsychotic use, specifically among Medicaid-reliant NHs. J Am Geriatr Soc 68:630-636, 2020.

Does older adults' use of social care influence their healthcare utilisation? A systematic review of international evidence

Improving our understanding of the complex relationship between health and social care utilisation is vital as populations age. This systematic review aimed to synthesise evidence on the relationship between older adults' use of social care and their healthcare utilisation. Ten databases were searched for international literature on social care (exposure), healthcare use (outcome) and older adults (population). Searches were carried out in October 2016, and updated May 2018. Studies were eligible if they were published after 2000 in a high income country, examined the relationship between use of social care and healthcare utilisation by older adults (aged ≥60 years), and controlled for an indicator of need. Study quality and bias were rated using the National Institute of Health (NIH) Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Study data were extracted and a narrative synthesis was conducted. Data were not suitable for quantitative synthesis. Thirteen studies were identified from 12,065 citations. Overall, the quality and volume of evidence was low. There was limited evidence to suggest that longer lengths of stay in care homes were associated with a lower risk of inpatient admissions. Residents of care homes with onsite nursing had fewer than expected admissions to hospital, compared to people in care homes without nursing, and adjusting for need. Evidence for other healthcare use outcomes was even more limited and heterogeneous, with notable gaps in primary care. We conclude that older adults' use of care homes may moderate inpatient admissions. In particular, the presence of registered nurses in care homes may reduce the need to transfer residents to hospital. However, further evidence is needed to add weight to this conclusion. Future research should build on this evidence and address gaps regarding the influence of community based social care on older adults' healthcare use. A greater focus on primary care outcomes is imperative.

Exploring social-based discrimination among nursing home certified nursing assistants

Certified nursing assistants (CNAs) provide the majority of direct care to nursing home residents in the United States and, therefore, are keys to ensuring optimal health outcomes for this frail older adult population. These diverse direct care workers, however, are often not recognized for their important contributions to older adult care and are subjected to poor working conditions. It is probable that social-based discrimination lies at the core of poor treatment toward CNAs. This review uses perspectives from critical social theory to explore the phenomenon of social-based discrimination toward CNAs that may originate from social order, power, and culture. Understanding manifestations of social-based discrimination in nursing homes is critical to creating solutions for severe disparity problems among perceived lower-class workers and subsequently improving resident care delivery.

Examining Black-White Disparities Among Medicare Beneficiaries in Assisted Living Settings in 2014

OBJECTIVE

Assisted living (AL) provides housing and personal care to residents who need assistance with daily activities. Few studies have examined black-white disparities in larger (25 + beds) ALs; therefore, little is known about black residents, their prior residential settings, and how they compare to whites in AL. We examined racial differences among a national cohort of AL residents and how the racial variation among AL Medicare Fee-For-Service (FFS) beneficiaries compared to differences among community-dwelling and nursing home cohorts.

STUDY DESIGN

Retrospective cohort study.

PARTICIPANTS

We included (1) a prevalence sample of 442,018 white and black Medicare beneficiaries residing in large AL settings, (2) an incidence sample of new residents (n = 94,741), and (3) 10% random samples of Medicare FFS community-dwelling and nursing home beneficiaries in 2014.

MEASURES

The Medicare Master Summary Beneficiary File was used to identify AL residents and provided demographic, entitlement, chronic condition, and health care utilization information. We used the American Community Survey and prior ZIP code tabulation areas of residents to examine differences in prior neighborhoods. Medicare claims and the Minimum Data Set yielded samples of Medicare FFS community-dwelling older adults and nursing home residents.

RESULTS

Blacks were disproportionately represented in AL, younger, more likely to be Medicaid eligible, had higher levels of acuity, and more often lived in ALs with fewer whites and more duals. New black residents entered AL with higher rates of acute care hospitalizations and skilled nursing facility utilization. Across the 3 cohorts, blacks had higher rates of dual-eligibility.

CONCLUSIONS

Black-white differences observed among AL residents indicate a need for future work to examine how disparities manifest in differences in care received and residents' outcomes, as well as the pathways to AL. More research is needed to understand the implications of inequities in AL as they relate to quality and experiences of residents.

Examining Racial and Ethnic Differences in Nursing Home Quality

BACKGROUND

Identifying racial/ethnic differences in quality is central to identifying, monitoring, and reducing disparities. Although disparities across all individual nursing home residents and disparities associated with between-nursing home differences have been established, little is known about the degree to which quality of care varies by race//ethnicity within nursing homes. A study was conducted to measure within-facility differences for a range of publicly reported nursing home quality measures.

METHODS

Resident assessment data on approximately 15,000 nursing homes and approximately 3 million residents (2009) were used to assess eight commonly used and publicly reported long-stay quality measures: the proportion of residents with weight loss, with high-risk and low-risk pressure ulcers, with incontinence, with depressive symptoms, in restraints daily, and who experienced a urinary tract infection or functional decline. Each measure was stratified by resident race/ethnicity (non-Hispanic white, non-Hispanic black, and Hispanic), and within-facility differences were examined.

RESULTS

Small but significant differences in care on average were found, often in an unexpected direction; in many cases, white residents were experiencing poorer outcomes than black and Hispanic residents in the same facility. However, a broad range of differences in care by race/ethnicity within nursing homes was also found.

CONCLUSION

The results suggest that care is delivered equally across all racial/ethnic groups in the same nursing home, on average. The results support the call for publicly reporting stratified nursing home quality measures and suggest that nursing home providers should attempt to identify racial/ethnic within-facility differences in care.

Nursing home quality and financial performance: does the racial composition of residents matter?

OBJECTIVE

To examine the effects of the racial composition of residents on nursing homes' financial and quality performance. The study examined Medicare and Medicaid-certified nursing homes across the United States that submitted Medicare cost reports between the years 1999 and 2004 (11,472 average per year).

DATA SOURCE

Data were obtained from the Minimum Data Set, the On-Line Survey Certification and Reporting, Medicare Cost Reports, and the Area Resource File.

STUDY DESIGN

Panel data regression with random intercepts and negative binomial regression were conducted with state and year fixed effects.

PRINCIPAL FINDINGS

Financial and quality performance differed between nursing homes with high proportions of black residents and nursing homes with no or medium proportions of black residents. Nursing homes with no black residents had higher revenues and higher operating margins and total profit margins and they exhibited better processes and outcomes than nursing homes with high proportions of black residents.

CONCLUSION

Nursing homes' financial viability and quality of care are influenced by the racial composition of residents. Policy makers should consider initiatives to improve both the financial and quality performance of nursing homes serving predominantly black residents.

Prevalence of incontinence by race and ethnicity of older people admitted to nursing homes

OBJECTIVE

While admissions of minorities to nursing homes (NHs) are increasing and prevalence of incontinence in NHs remains high, little is known about incontinence among racial-ethnic groups of NH admissions other than blacks. The purpose of this study was to describe the prevalence of incontinence among older adults admitted to NHs by race/ethnicity at three levels of measurement: individual resident, NH, and Census division.

DESIGN

Cross-sectional and descriptive.

PARTICIPANTS AND SETTING

Admissions of persons age 65 or older to 1 of 457 NHs of a national, for-profit chain over 3 years 2000-2002 (n = 111,640 residents).

METHODS

Data sources were the Minimum Data Set v. 2.0 and 2000 US Census. Prevalence of the following definitions of incontinence was analyzed: Only Urinary Incontinence (UI), Only Fecal Incontinence (FI), Dual Incontinence (DI; UI and FI), Any UI (UI with or without FI), Any FI (FI with or without UI), and Any Incontinence (UI and/or FI and/or DI).

RESULTS

Asian patients, black patients, and Hispanic patients had a higher prevalence of Any Incontinence (67%, 66%, and 58%, respectively) compared to white patients (48%) and American Indian patients (46%). At the NH level, all prevalence measures of incontinence (except Only UI) appear to trend in the opposite direction from the percentage of NH admissions who were white. Among Asian and white patients, there was a higher prevalence of all types of incontinence in men compared with women except for Only UI. Among Census divisions, the prevalence of all types of incontinence, except Only UI, was lowest in the 2 divisions with the highest percentage of white admissions to their NHs.

CONCLUSIONS

NHs admitting more racial/ethnic minorities may be faced with managing more incontinence and needing additional staffing resources. The association of the prevalence of most types of incontinence with the race/ethnicity of NH admissions at all levels of measurement lend support to the growing evidence that contextual factors beyond individual resident characteristics may contribute to NH differences.

Medicaid bed-hold policies and hospitalization of long-stay nursing home residents

OBJECTIVE

To evaluate the effect of Medicaid bed-hold policies on hospitalization of long-stay nursing home residents.

DATA SOURCES

A nationwide random sample of long-stay nursing home residents with data elements from Medicare claims and enrollment files, the Minimum Data Set, the Online Survey Certification and Reporting System, and Area Resource File. The sample consisted of 22,200,089 person-quarters from 754,592 individuals who became long-stay residents in 17,149 nursing homes over the period beginning January 1, 2000 through December 31, 2005.

STUDY DESIGN

Linear regression models using a pre/post design adjusted for resident, nursing home, market, and state characteristics. Nursing home and year-quarter fixed effects were included to control for time-invariant facility influences and temporal trends associated with hospitalization of long-stay residents.

PRINCIPAL FINDINGS

Adoption of a Medicaid bed-hold policy was associated with an absolute increase of 0.493 percentage points (95% CI: 0.039-0.946) in hospitalizations of long-stay nursing home residents, representing a 3.883 percent relative increase over the baseline mean.

CONCLUSIONS

Medicaid bed-hold policies may increase the likelihood of hospitalization of long-stay nursing home residents and increase costs for the federal Medicare program.

The relationships among licensed nurse turnover, retention, and rehospitalization of nursing home residents

PURPOSE

Individuals receiving postacute care in skilled nursing facilities often require complex, skilled care provided by licensed nurses. It is believed that a stable set of nursing personnel is more likely to deliver better care. The purpose of this study was to determine the relationships among licensed nurse retention, turnover, and a 30-day rehospitalization rate in nursing homes (NHs).

DESIGN AND METHODS

We combined two data sources: NH facility-level data (including characteristics of the facility, the market, and residents) and the Florida Nursing Home Staffing Reports (which provide staffing information for each NH) for 681 Florida NHs from 2002 to 2009. Using a two-way fixed effects model, we examined the relationships among licensed nurse turnover rates, retention rates, and 30-day rehospitalization rates.

RESULTS

Results indicate that an NH's licensed nurse retention rate is significantly associated with the 30-day rehospitalization rate (est. = -.02, p = .04) controlling for demographic characteristics of the patient population, residents' preferences for hospitalization, and the ownership characteristics of the NH. The NHs experiencing a 10% increase in their licensed nurse retention had a 0.2% lower rehospitalization rate, which equates to 2 fewer hospitalizations per NH annually. Licensed nurse turnover is not significantly related to the 30-day rehospitalization rate.

IMPLICATIONS

These findings highlight the need for NH administrators and policy makers to focus on licensed nurse retention, and future research should focus on the measures of staff retention for understanding the staffing/quality relationship.

Racial inequities in receipt of influenza vaccination among nursing home residents in the United States, 2008-2009: a pattern of low overall coverage in facilities in which most residents are black

OBJECTIVES

Nationwide among nursing home residents, receipt of the influenza vaccine is 8 to 9 percentage points lower among blacks than among whites. The objective of this study was to determine if the national inequity in vaccination is because of the characteristics of facilities and/or residents.

DESIGN

Cross-sectional study with multilevel modeling.

SETTING AND PARTICIPANTS

States in which 1% or more of nursing home residents were black and the difference in influenza vaccination coverage between white and black nursing home residents was 1 percentage point or higher (n = 39 states and the District of Columbia). Data on residents (n = 2,359,321) were obtained from the Centers for Medicare & Medicaid Service's Minimum Data Set for October 1, 2008, through March 31, 2009.

MEASUREMENTS

Residents' influenza vaccination status (vaccinated, refused vaccine, or not offered vaccination).

RESULTS

States with higher overall influenza vaccination coverage among nursing home residents had smaller racial inequities. In nursing homes with higher proportions of black residents, vaccination coverage was lower for both blacks and whites. The most dramatic inequities existed between whites in nursing homes with 0% blacks (L1) and blacks in nursing homes with 50% or more blacks (L5) in states with overall racial inequities of 10 percentage points or more. In these states, more black nursing home residents lived in nursing homes with 50% or more blacks (L5); in general, the same homes with low overall coverage.

CONCLUSION

Inequities in influenza vaccination coverage among nursing home residents are largely because of low vaccination coverage in nursing homes with a high proportion of black residents. Findings indicate that implementation of culturally appropriate interventions to increase vaccination in facilities with larger proportions of black residents may reduce the racial gap in influenza vaccination as well as increase overall state-level vaccination.

Racial differences in dementia care among nursing home residents

OBJECTIVES

This article aims to describe potential racial differences in dementia care among nursing home residents with dementia.

METHODS

Using data from the 2004 National Nursing Home Survey (NNHS) in regression models, the authors examine whether non-Whites are less likely than Whites to receive special dementia care--defined as receiving special dementia care services or being in a dementia special care unit (SCU)--and whether this difference derives from differences in resident or facility characteristics.

RESULTS

The authors find that non-Whites are 4.3 percentage points less likely than Whites to receive special dementia care.

DISCUSSION

The fact that non-Whites are more likely to rely on Medicaid and less likely to pay out of pocket for nursing home care explains part but not all of the difference. Most of the difference is due to the fact that non-Whites reside in facilities that are less likely to have special dementia care services or dementia care units, particularly for-profit facilities and those in the South.

Health care segregation and race disparities in infectious disease: the case of nursing homes and seasonal influenza vaccinations

Examining nursing home segregation and race disparities in influenza vaccinations, this study demonstrates that segregation may increase both susceptibility and exposure to seasonal flu for black Americans. Evidence based on the 2004 U.S. National Nursing Home Survey shows that individuals in nursing homes with high percentages of black residents have less personal immunity to flu because they are less likely to have been vaccinated against the disease; they may also be more likely to be exposed to flu because more of their coresidents are also unvaccinated. This implies that segregation may generate dual disease hazards for contagious conditions. Segregation appears to limit black Americans' access to personal preventive measures against infection, while spatially concentrating those people who are most likely to become contagious.

Racial disparities in in-hospital death and hospice use among nursing home residents at the end of life

BACKGROUND

Significant racial disparities have been reported regarding nursing home residents' use of hospital and hospice care at the end of life (EOL).

OBJECTIVE

To examine whether the observed racial disparities in EOL care are due to within-facility or across-facility variations.

RESEARCH DESIGN AND SUBJECTS

Cross-sectional study of 49,048 long-term care residents (9.23% black and 90.77% white) in 555 New York State nursing homes who died during 2005-2007. The Minimum Data Set was linked with Medicare inpatient and hospice claims.

MEASURES

In-hospital death determined by inpatient claims and hospice use determined by hospice claims. For each outcome, risk factors were added sequentially to examine their partial effects on the racial differences. Hierarchical models were fit to test whether racial disparities are due to within-facility or across-facility variations.

RESULTS

40.33% of blacks and 24.07% of whites died in hospitals; 11.55% of blacks and 17.39% of whites used hospice. These differences are partially due to disparate use of feeding tubes, do-not-resuscitate and do-not-hospitalize orders. We find no racial disparities in in-hospital death [odds ratio (OR) of race=0.95; 95% confidence interval (CI), 0.87-1.04] or hospice use (OR of race=0.90, 95% CI, 0.79-1.02) within same facilities. Living in facilities with 10% more blacks increases the odds of in-hospital death by 22% (OR=1.22, 95% CI, 1.17-1.26) and decreases the odds of hospice use by 15% (OR=0.85, 95% CI, 0.78-0.94).

CONCLUSIONS

Differential use of feeding tubes, do-not-resuscitate and do-not-hospitalize orders lead to racial differences in in-hospital death and hospice use. The remaining disparities are primarily due to overall EOL care practices in predominately black facilities, not to differential hospitalization and hospice-referral patterns within facilities.

Racial disparities in rehospitalization among Medicare patients in skilled nursing facilities

OBJECTIVES

We examined racial disparities in rehospitalization rates among a cohort of non-Hispanic White and Black Medicare beneficiaries admitted to skilled nursing facilities for postacute care.

METHODS

We analyzed the 2008 national Nursing Home Minimum Data Set, augmented with other databases. We used multivariable logistic regression to estimate overall racial disparities in rehospitalization rates within 30 days and 90 days of nursing facility admission and the extent to which the disparities were explained by patient, facility, market, and state factors. Stratified analyses identified persistent disparities within patient subgroups, facility types, and states.

RESULTS

The 30-day rehospitalization rates were 14.3% for White patients (n = 865 993) and 18.6% for Black patients (n = 94 651); the 90-day rehospitalization rates were 22.1% and 29.5%, respectively. Both patient and admitting facility characteristics accounted for a considerable portion of overall racial disparities, but disparities persisted after multivariable adjustments overall and in patient subgroups.

CONCLUSIONS

We found persistent racial disparities in rehospitalization among the nation's skilled nursing facility patients receiving postacute care. Targeted efforts are needed to remove these disparities.

Temporal and Geographic variation in the validity and internal consistency of the Nursing Home Resident Assessment Minimum Data Set 2.0

Background

The Minimum Data Set (MDS) for nursing home resident assessment has been required in all U.S. nursing homes since 1990 and has been universally computerized since 1998. Initially intended to structure clinical care planning, uses of the MDS expanded to include policy applications such as case-mix reimbursement, quality monitoring and research. The purpose of this paper is to summarize a series of analyses examining the internal consistency and predictive validity of the MDS data as used in the "real world" in all U.S. nursing homes between 1999 and 2007.

Methods

We used person level linked MDS and Medicare denominator and all institutional claim files including inpatient (hospital and skilled nursing facilities) for all Medicare fee-for-service beneficiaries entering U.S. nursing homes during the period 1999 to 2007. We calculated the sensitivity and positive predictive value (PPV) of diagnoses taken from Medicare hospital claims and from the MDS among all new admissions from hospitals to nursing homes and the internal consistency (alpha reliability) of pairs of items within the MDS that logically should be related. We also tested the internal consistency of commonly used MDS based multi-item scales and examined the predictive validity of an MDS based severity measure viz. one year survival. Finally, we examined the correspondence of the MDS discharge record to hospitalizations and deaths seen in Medicare claims, and the completeness of MDS assessments upon skilled nursing facility (SNF) admission.

Results

Each year there were some 800,000 new admissions directly from hospital to US nursing homes and some 900,000 uninterrupted SNF stays. Comparing Medicare enrollment records and claims with MDS records revealed reasonably good correspondence that improved over time (by 2006 only 3% of deaths had no MDS discharge record, only 5% of SNF stays had no MDS, but over 20% of MDS discharges indicating hospitalization had no associated Medicare claim). The PPV and sensitivity levels of Medicare hospital diagnoses and MDS based diagnoses were between .6 and .7 for major diagnoses like CHF, hypertension, diabetes. Internal consistency, as measured by PPV, of the MDS ADL items with other MDS items measuring impairments and symptoms exceeded .9. The Activities of Daily Living (ADL) long form summary scale achieved an alpha inter-consistency level exceeding .85 and multi-item scale alpha levels of .65 were achieved for well being and mood, and .55 for behavior, levels that were sustained even after stratification by ADL and cognition. The Changes in Health, End-stage disease and Symptoms and Signs (CHESS) index, a summary measure of frailty was highly predictive of one year survival.

Conclusion

The MDS demonstrates a reasonable level of consistency both in terms of how well MDS diagnoses correspond to hospital discharge diagnoses and in terms of the internal consistency of functioning and behavioral items. The level of alpha reliability and validity demonstrated by the scales suggest that the data can be useful for research and policy analysis. However, while improving, the MDS discharge tracking record should still not be used to indicate Medicare hospitalizations or mortality. It will be important to monitor the performance of the MDS 3.0 with respect to consistency, reliability and validity now that it has replaced version 2.0, using these results as a baseline that should be exceeded.

Discharge destination's effect on bounce-back risk in Black, White, and Hispanic acute ischemic stroke patients

OBJECTIVE

To determine whether racial and ethnic effects on bounce-back risk (ie, movement to settings of higher care intensity within 30 d of hospital discharge) in acute stroke patients vary depending on initial posthospital discharge destination.

DESIGN

Retrospective analysis of administrative data.

SETTING

Four hundred twenty-two hospitals, southern/eastern United States.

PARTICIPANTS

All Medicare beneficiaries 65 years or more with hospitalization for acute ischemic stroke within one of the 422 target hospitals during the years 1999 or 2000 (N=63,679).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Adjusted predicted probabilities for discharge to and for bouncing back from each initial discharge site (ie, home, home with home health care, skilled nursing facility [SNF], or rehabilitation center) by race (ie, black, white, and Hispanic). Models included sociodemographics, comorbidities, stroke severity, and length of stay.

RESULTS

Blacks and Hispanics were significantly more likely to be discharged to home health care (blacks=21% [95% confidence interval (CI), 19.9-22.8], Hispanic=19% [17.1-21.7] vs whites=16% [15.5-16.8]) and less likely to be discharged to SNFs (blacks=26% [95% CI, 23.6-29.3], Hispanics=28% [25.4-31.6] vs whites=33% [31.8-35.1]) than whites. However, blacks and Hispanics were significantly more likely to bounce back when discharged to SNFs than whites (blacks=26% [95% CI, 24.2-28.6], Hispanics=28% [24-32.6] vs whites=21% [20.3-21.9]). Hispanics had a lower risk of bouncing back when discharged home than either blacks or whites (Hispanics=14% [95% CI, 11.3-17] vs blacks=20% [18.4-22.2], whites=18% [16.8-18.3]). Patients discharged to home health care or rehabilitation centers demonstrated no significant differences in bounce-back risk.

CONCLUSIONS

Racial/ethnic bounce-back risk differs depending on initial discharge destination. Additional research is needed to fully understand this variation in effect.
