The moderating role of housing quality on concentrated poverty and asthma-related emergency department visits among Hispanics/Latinos.

BACKGROUND: Rates of asthma-related emergency department visits have been shown to vary significantly by place (i.e. neighborhood) and race/ethnicity. The moderating factors of asthmatic events among Hispanic/Latino-specific populations are known to a much lesser degree. OBJECTIVE: To assess the extent to which housing moderates the effect of poverty on Hispanic/Latino-specific asthma-related emergency department (ED) visits at an ecological level. METHODS: Using data from the Office of Statewide Health Planning and Development (OSHPD) and the 2016-2017 U.S. Census, a cross-sectional ecological analysis at the census tract-level was conducted. Crosswalk files from the U.S. Department of Housing and Urban Development were used to associate zip codes to census tracts. Negative binomial regression was used to estimate rate ratios. RESULTS: The effect of poverty on asthma-related ED visits was significantly moderated by the median year of housing structures built. The effect of mid-level poverty (RR = 1.57, 95% CI 1.27, 1.95) and high-level poverty (RR = 1.47, 95% CI 1.22, 1.78) in comparison to low-level poverty, was significantly greater among census tracts with housing built prior to 1965 in comparison to census tract with housing built between 1965 and 2020. CONCLUSION: Communities with older housing structures tend to be associated with increased Hispanic/Latino ED visits apart from affluent communities.

Health care access, concentrated poverty, and pediatric asthma hospital care use in California's San Joaquin Valley: A multilevel approach.

BACKGROUND: California's San Joaquin Valley is a region with a history of poverty, low health care access, and high rates of pediatric asthma. It is important to understand the potential barriers to care that challenge vulnerable populations. OBJECTIVE: The objective was to describe pediatric asthma-related utilization patterns in the emergency department (ED) and hospital by insurance coverage as well as to identify contributing individual-level indicators (age, sex, race/ethnicity, and insurance coverage) and neighborhood-level indicators of health care access. METHODS: This was a retrospective study based on secondary data from California hospital and ED records 2007-2012. Children who used services for asthma-related conditions, were aged 0-14 years, Hispanic or non-Hispanic white, and resided in the San Joaquin Valley were included in the analysis. Poisson multilevel modeling was used to control for individual- and neighborhood-level factors. RESULTS: The effect of insurance coverage on asthma ED visits and hospitalizations was modified by the neighborhood-level percentage of concentrated poverty (RR = 1.01, 95% CI = 1.01-1.02; RR = 1.03, 95% CI = 1.02-1.04, respectively). The effect of insurance coverage on asthma hospitalizations was completely explained by the neighborhood-level percentage of concentrated poverty. CONCLUSIONS: Observed effects of insurance coverage on hospital care use were significantly modified by neighborhood-level measures of health care access and concentrated poverty. This suggests not only an overall greater risk for poor children on Medi-Cal, but also a greater vulnerability or response to neighborhood social factors such as socioeconomic status, community cohesiveness, crime, and racial/ethnic segregation.

Pollution, Poverty, and Potentially Preventable Childhood Morbidity in Central California.

OBJECTIVE: To measure ecological relationships between neighborhood pollution burden, poverty, race/ethnicity, and pediatric preventable disease hospitalization rates. STUDY DESIGN: Preventable disease hospitalization rates were obtained from the 2012 California Office of Statewide Health Planning and Development database, for 8 Central Valley counties. US Census Data was used to incorporate zip code level factors including racial diversity and poverty rates. The pollution burden score was calculated by the California Office of Environmental Health Hazard Assessment using 11 indicators. Poisson-based negative binomial regression was used for final analysis. Stratification of sample by age, race/ethnicity, and insurance coverage was also incorporated. RESULTS: Children experiencing potentially preventable hospitalizations are disproportionately low income and under the age of 4 years. With every unit increase in pollution burden, preventable disease hospitalizations rates increase between 21% and 32%, depending on racial and age subgroups. Although living in a poor neighborhood was not associated with potentially avoidable hospitalizations, children enrolled in Medi-Cal who live in neighborhoods with lower pollution burden and lower levels of poverty, face 32% lower risk for ambulatory care sensitive condition hospitalization. Children living in primary care shortage areas are at increased risk of preventable hospitalizations. Preventable disease hospitalizations increase for all subgroups, except white/non-Hispanic children, as neighborhoods became more racially diverse. CONCLUSIONS: Understanding the geographic distribution of disease and impact of individual and community level factors is essential to expanding access to care and preventive resources to improve the health of children in California's most polluted and underserved region.

Can more use of supporting primary care health practitioners increase efficiency of health clinics? Evidence from California's San Joaquin Valley.

This study examined 67 primary health care centers operating in the San Joaquin Valley, California, and explored the factors that may have contributed to productive efficiency gains. The study used the data envelopment analysis (DEA) technique to measure efficiency of the clinics and then used tobit regression analysis to understand the factors that affected efficiency. It was found that clinics that employed relatively more "unlicensed" supporting practitioners compared to "licensed" practitioners were more likely to be efficient. The results also showed that clinics that employed fewer physicians compared to all "licensed" practitioners were likely to be more efficient. In addition, providing transportation services to patients also enhanced clinics' efficiency.

Disparities in initiation and adherence to prenatal care: impact of insurance, race-ethnicity and nativity.

We used the intersectionality framework to examine impact of racial/ethnic, immigration, and insurance differences on the timing of initiation of prenatal care (PNC) and subsequent adherence. In this cross sectional study independent variables were women's race/ethnicity; nativity; age; education; and insurance. The dependent variables were late initiation and non-adherence to recommended number of PNC visits. We used multivariate analysis to evaluate the impact of the independent variables on late initiation and non-adherence. Analysis revealed that race/ethnicity/nativity (RE-N) was more consistently associated with late initiation and non-adherence for privately insured than publicly insured persons. While private insurance had a positive impact on initiation and adherence overall, its impact was greater for White women. Having private insurance coverage was most beneficial to White women. We contend that the intersectional approach provides promising avenues for expanding our knowledge of health disparities and of identifying new ways of going about eliminating the persistent and pervasive social inequalities and informing efforts to reduce them.

Community-based disability prevention programs for elders: predictors of program completion.

Strategies to foster elder well-being and reduce long-term care costs include efficacious community disability prevention programs. Program completion remains an important barrier to their effectiveness. We examined the association between provider relationships and client variables, and program completion in senior centers. Our mixed methods design used secondary data for 719 clients and primary data through telephone interviews with 20 nurses, 23 social workers, and 18 site managers. Quantitative data showed that higher client baseline self-efficacy positively influenced completion and minority status negatively influenced completion. Qualitative data showed that higher focus on provider-client relationships was associated with high completion.

Cumulative Impact of Environmental Pollution and Population Vulnerability on Pediatric Asthma Hospitalizations: A Multilevel Analysis of CalEnviroScreen.

The CalEnviroScreen created by the Office of Environmental Health Hazard Assessment, Sacramento, USA, is a place-based dataset developed to measure environmental and social indicators that are theorized to have cumulative health impacts on populations. The objective of this study was to examine the extent to which the composite scores of the CalEnviroScreen tool are associated with pediatric asthma hospitalization. This was a retrospective analysis of California hospital discharge data from 2010 to 2012. Children who were hospitalized for asthma-related conditions, were aged 0-14 years, and resided in California were included in analysis. Rates of hospitalization for asthma-related conditions among children residing in California were calculated. Poisson multilevel modeling was used to account for individual- and neighborhood-level risk factors. Every unit increase in the CalEnviroScreen Score was associated with an increase of 1.6% above the mean rate of pediatric asthma hospitalizations (rate ratio (RR) = 1.016, 95% confidence interval (CI) = 1.014-1.018). Every unit increase in racial/ethnic segregation and diesel particulate matter was associated with an increase of 1.1% and 0.2% above the mean rate of pediatric asthma, respectively (RR = 1.011, 95% CI = 1.010-1.013; RR = 1.002, 95% CI = 1.001-1.004). The CalEnviroScreen is a unique tool that combines socioecological factors and environmental indicators to identify vulnerable communities with major health disparities, including pediatric asthma hospital use. Future research should identify mediating factors that contribute to community-level health disparities.

The Association Between the Intersection of Immigrant Status and Insurance with Adverse Birth Outcomes Among Mexican Women Residing in the San Joaquin Valley: A Mediation Analysis of Late Initiation or No Prenatal Care.

Latinos are the largest growing population and have the highest fertility rates in the US. In response, this study assessed if late initiation of or no prenatal care (PNC) mediated the relationship among adverse birth outcomes and interactions between immigrant and insurance status. This study used cross-sectional data (2002-2004) limited to 109,399 women of Mexican ethnicity who had singleton births in the San Joaquin Valley, California. We conducted hierarchical mediation analyses. US-born Mexican women who used private or public insurance for PNC were more likely to have infants born at low-birth weight and premature compared to Mexican first generation immigrant women. Nonetheless, initiation of late or no PNC positively mediated the relationship between infants born premature to Mexican first generation immigrant women who used public insurance (ab/se(ab) = 2.123, p = .034). Findings from this study support acculturation theory and the need for multilevel approaches to address PNC among women of Mexican ethnicity.

Poor People Are Hospitalized Three Times More for Mental Health Services than the Non-Poor in Central Valley California.

Introduction: Providing health insurance to the poor has become a standard policy response to health disparities between the poor and the non-poor. It is often assumed that if the poor people are given health insurance, they will use preventative care, which will prevent more expensive emergency visits and inpatient hospitalization, and in turn, it will save healthcare cost in the long run. This paper presents the findings from our study in California about what happens to the poor when they are given health insurance. The purpose of the study was to understand how the healthcare system in California treats the poor patients differently than the non-poor. Method: Using multivariate logistic regressions, this study analyzed a large patient discharge data (PDD) from the California Office of Statewide Planning and Development (OSHPD) for eight counties in the Central Valley California (N = 423,640). First, utilizing International Classification of Diseases (ICD 10) as diagnostic criteria, mental-health vs. non-mental health hospitalization rates were estimated. Second, health insurance status was used as a proxy measure of poverty of the patients. Using chi-Square, the probability of hospitalization for mental health services was estimated based on their insurance types. Finally, using step-wise logistic regression, the odds of mental health hospitalization was estimated conditional on individual characteristics, health insurance types, and geographic characteristics. Findings: When the poor people were given health insurance, they were three times more likely to be hospitalized for mental health services than the non-poor. The more than three-fold variation in mental health hospitalization was not driven by demographic or geographic characteristics. The findings are new and have important implications for the healthcare policies for the poor. Further studies are needed to understand the extent to which the disproportionately high rate of mental health hospitalizations of the poor are driven by the provider-induced needs.

Preventing illegal tobacco and alcohol sales to minors through electronic age-verification devices: a field effectiveness study.

Efforts to prohibit the sales of tobacco and alcohol products to minors are widespread. Electronic Age Verification (EAV) devices are one possible means to improve compliance with sales to minors laws. The purpose of this study was to evaluate the implementation and effectiveness of EAV devices in terms of the frequency and accuracy of age verification, as well as to examine the impact of EAV's on the retailer environment. Two study locations were selected: Tallahassee, Florida and Iowa City, Iowa. Retail stores were invited to participate in the study, producing a self-selected experimental group. Stores that did not elect to test the EAV's comprised the comparison group. The data sources included: 1) mystery shopper inspections: two pre- and five post-EAV installation mystery shopper inspections of tobacco and alcohol retailers; 2) retail clerk and manager interviews; and 3) customer interviews. The study found that installing EAV devices with minimal training and encouragement did not increase age verification and underage sales refusal. Surveyed clerks reported positive experiences using the electronic ID readers and customers reported almost no discomfort about being asked to swipe their IDs. Observations from this study support the need for a more comprehensive system for responsible retailing.

Consumer-directed community care: race/ethnicity and individual differences in preferences for control.

PURPOSE: Even though consumer-directed care models are being advocated for use among elder populations, there are few data on the extent of elder interest in participating in the management of community long-term-care services, who they want involved in making these decisions, or their perceptions regarding the relative importance of different service choices. In addition, little is known about how elder preferences for consumer direction may vary by race/ethnicity. DESIGN AND METHODS: With use of a cross-sectional research design, a sample of 731 elders including 200 African American, 200 Chinese, 131 Latino, and 200 White Western European American elders was investigated. New measures were created to assess level of control desired by elders in different areas of community long-term-care service delivery and preference for consumer direction. RESULTS: Multivariate analyses found significant differences between and within race/ethnic groups for preferences for levels of consumer-directed care. IMPLICATIONS: Study findings suggest that consumer direction occurs along a continuum, with elders desiring control over some service areas but not others, and the importance of recognizing heterogeneity within racial/ethnic groups regarding consumer-directed care.

Implementation challenges and functional outcome predictors for elder community-based disability prevention programs.

BACKGROUND AND PURPOSE: Strategies to foster elder well-being and reduce long-term care costs include efficacious community disability prevention programs. However, it is often difficult to replicate clinical trials into real-world practice settings. We (a) compared replication and clinical trial functional changes, (b) compared replication and clinical trial program structures and processes of care, and, additionally, (c) examined how replication client and site features are associated with function. METHODS: We used secondary longitudinal data on 719 elder clients, and primary data through interviews with nurses, social workers, and site managers for the replication, and compared this to original trial data. We analyzed associations between baseline self-efficacy and functional outcomes and between site features and functional outcomes using multivariate and logistic models for the replication. RESULTS: Replication functional outcome changes were lower and structures and processes were less intense than in the original clinical trial. Baseline client higher self-efficacy positively influenced 12-month function, and smaller sites and urban sites had better functional outcomes than larger sites and rural sites for the replication. DISCUSSION AND CONCLUSION: Exploring systemic strategies for using available resources to improve research translation is essential. In addition, practitioners need to focus on client self-efficacy enhancement techniques, which may be more important in replication studies to improve function.

Policy barriers to health care access fuel discriminatory treatment: the role of Promotoras in overcoming malos tratos.

This article demonstrates that policy barriers resulting in access to health care inequities were significantly decreased by 2 Promotora interventions for 416 legal and undocumented Latino immigrants in the California Central Valley. Promotoras conducted baseline/follow-up assessments and referrals/phone-calls/visits during a 3-month period. In-depth interviews with Promotoras and a policy analysis on policy-driven access programs were carried out. Access to care was significantly increased between legal and undocumented immigrant from baseline to follow-up. Systemic barriers to access (malos tratos) reflected on personal barriers such as affordability of care. Promotoras help participants overcome barriers but do not change the policies determining access and procedures.

Lay health mentors in community-based older adult disability prevention programs: provider perspectives.

In this study, we explored provider perspectives on the benefits of and implementation challenges in using lay health mentor peers in a community-based replication of an efficacious 12-month older adult disability prevention program. In addition, we describe the association of the mentor program with site features and program completion. We conducted semi-structured telephone interviews with nurses, social workers, and site managers and obtained primary data on site features and secondary data on program completion. Major themes included the importance of the health mentor program and implementation challenges. Sites with mentor programs were more likely to have older adults complete the program compared with sites without mentor programs. Rural, small, and less diverse sites were more likely to have health mentor programs than urban, large, and more diverse sites. Implications include a need to fund more lay health mentor programs, obtain adequate staffing including minority staff for health mentor support, and implement strategies to improve program efficiency.

Measuring patient-level clinical outcomes of home health care.

PURPOSE: To examine the use of the Outcomes Assessment and Information Set (OASIS) data to analyze patient-level outcomes of home health care. DESIGN: OASIS data were obtained on 1,015 patients who received home health care services for 60 days or fewer from a large, independent home health agency between August 1998 and December 1999. METHODS: An index was constructed consisting of 16 OASIS measures, primarily activities of daily living (ADL) and instrumental activities of daily living (IADL). Scores were computed for functional status on admission and at discharge. Predictors of functional status at discharge were identified by regression analysis. FINDINGS: 78.1% of patients improved, 18.5% declined, and 2.8% showed no change. The model explained 57.2% of variance in functional status at discharge. Age, visual impairment, having Medicaid as a payer, urinary incontinence, cognitive impairment, and use of unplanned or emergency care were negatively associated with functional outcomes of care. Being treated for open wounds or lesions, cardiovascular and orthopedic conditions were positively associated with functional outcomes. CONCLUSIONS: OASIS data can be used to analyze patient-level functional outcomes of short-term home health services. Further research is needed to continue refining methods of analyzing patient outcomes and their predictors.
