Addressing refugee health through evidence-based policies: A case study
(Elsevier, 2018-06) Thiel de Bocanegra, Heike; Carter-Pokras, Olivia; Ingleby, J. David; Pottie, Kevin; Tchangalova, Nedelina; Allen, Sophia I.; Smith-Gagen, Julie; Hidalgo, Bertha
The cumulative total of persons forced to leave their country for fear of persecution or organized violence reached an unprecedented 24.5 million by the end of 2015. Providing equitable access to appropriate health services for these highly diverse newcomers poses challenges for receiving countries. In this case study, we illustrate the importance of translating epidemiology into policy to address the health needs of refugees by highlighting examples of what works as well as identifying important policy-relevant gaps in knowledge. First, we formed an international working group of epidemiologists and health services researchers to identify available literature on the intersection of epidemiology, policy, and refugee health. Second, we created a synopsis of findings to inform a recommendation for integration of policy and epidemiology to support refugee health in the United States and other high-income receiving countries. Third, we identified eight key areas to guide the involvement of epidemiologists in addressing refugee health concerns. The complexity and uniqueness of refugee health issues, and the need to develop sustainable management information systems, require epidemiologists to expand their repertoire of skills to identify health patterns among arriving refugees, monitor access to appropriately designed health services, address inequities, and communicate with policy makers and multidisciplinary teams.
ADVANCING THE HEALTH OF UNDERSERVED COMMUNITIES ACROSS THE UNITED STATES: OPPORTUNITIES TO IMPROVE HEALTH CENTER QUALITY OF CARE AND PATIENT EXPERIENCE
(2017) Nair, Suma; Chen, Jie; Health Services Administration; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
1 in 13 people in the United States receives care at a community health center. As health center services become an increasing percentage of all primary care services delivered in the United States, their success is vital to national efforts to advance health and manage costs. This dissertation presents three studies, addressing critical gaps in our understanding of health center quality and quality improvement opportunities. The first study examined the association between ambulatory care accreditation and 14 clinical quality measures in 1,198 health centers. Results demonstrated that accredited centers achieved higher performance on adult weight screening and follow up, tobacco cessation intervention, and use of lipid-lowering therapy. Universal accreditation could lead to an additional 552,087 patients receiving weight screening and follow up, 157,434 receiving tobacco cessation interventions, and 25,289 receiving lipid-lowering therapy. Findings suggest universal accreditation could contribute to quality gains and facilitate health disparity reduction. The second study used the first nationally representative dataset of health center PEC, to investigate the association between five measures of PEC (access to care, provider communication, office staff interactions, follow up on results and overall provider rating) and patient and health center characteristics. Results demonstrated that PEC ratings varied significantly by race/ethnicity, health and mental health status, education and income levels, and language. Findings highlight PEC improvement opportunities as well as the importance of patient-mix adjustment of PEC ratings in value-based payment. The third study evaluated the association between PEC and health center quality of care. Quality of care metrics included receipt of care, health behaviors, patient activation, and clinical outcomes in health center patients. Results showed that PEC ratings were associated with receipt of care, as well as patient adherence and activation. The findings support the importance of measuring PEC as a key determinant of quality, as well improving PEC as a driver for improvement for other aspects of care quality. All three studies were the first to our knowledge to use nationally representative health center data to examine these dimensions of quality and provide significant contributions towards our understanding of health center quality and related quality improvement and policy implications.
Adverse Childhood Experiences and Preterm Birth: A Systematic Review
(2019) Wiggan, Morgan Lynn; Franzin, Luisa; Shenassa, Edmond; Health Services Administration; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Adverse childhood Experiences (ACEs) elevate one’s risk for poor health outcomes later in life such as psychiatric disorders, cardiovascular disease, depression, anxiety, obesity, diabetes, poor fetal health, and liver disease (Poulton et al., 2002, Anda et al., 2007, Jimenez et al., 2017, Talbot et al., 2009. While the association between ACEs and negative health outcomes is well established in the literature, only ten studies examine the effect of ACEs on one’s risk for preterm birth (Benedict et al. 1999; Bublitz et al., 2014; Cammack et al., 2019; Christiaens et al. 2015; Jacobs 1998; Gillespie et al. 2017; Grimstad et al. 1998; Leeners et al. 2010; Margerison-Zilko et al., 2016; Noll et al. 2007). Preterm birth accounts for 60% of neonatal deaths and elevates an infant’s risk for poor health outcomes later in life ranging from behavioral issues to heart disease (WHO, 2018) and the rate of preterm birth in the United States has steadily risen since 2015, reaching about 10% in 2018 (CDC, 2018). This systematic review seeks to critically assess and synthesize these ten studies and identify proposed mediators and identify gaps in the literature for future research.
Analyzing the Effect of Vaping Use in Teens: A Literature Review and Proposed Solutions
(Journal of Student Research, 2021-03-31) Ajayi, Damilola; Fuchs, Bruce; Reiss, Dana
Teenage vaping is a major public health issue that is emerging globally. This review article examines what influences teens to use electronic cigarettes (e-cigarettes) and vapes, including families, communities, social media, and brand marketing. Nicotine, a common component of e-cigarettes and vapes, is addictive, and teens who are using these products are starting to report negative health outcomes. After a review of the current literature, three recommendations/solutions are proposed to combat this public health issue. As teen e-cigarette use is on the rise, it is clear that the FDA and the federal government need to enforce tougher regulations on e-cigarette and vaping brands, teens need to be properly educated about these products that are on the market, and advertisements for these products need to be regulated.
Assessing Changes in Access to Health care and Utilization of Preventive Services among Immigrants of African Descent Before and After Implementation of the Affordable Care Act
(2020) Williams-Parry, Kester F; Chen, Jie; Thomas, Stephen B.; Health Services Administration; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
In the U.S., African Americans experience a disproportionate burden of health disparities. The African American population includes 4.3 million people who are foreign-born. Yet, a paucity of empirical data exists on the health of immigrants of African descent. The lack of data disaggregation by subpopulations of African Americans, disregards the unique characterization of the African American diaspora and the influence of different cultural, linguistic, political, social, economic, environmental, and historical experience on the overall health of the population. Access to health care including lack of health insurance coverage has been a longstanding contributor to poor health outcomes among African Americans. The passage of the Affordable Care Act aimed to improve access to care including health insurance coverage and utilization of preventive services with no cost-sharing. Studies have shown significant reductions in the uninsured rate among African Americans and uptake in some preventive services, but the impact of the ACA on immigrants of African descent is not well understood. This dissertation research examined changes in access to health care, and utilization of preventive screenings for cancer, high blood pressure, diabetes, and high cholesterol among immigrants of African descent and U.S.-born African Americans before and after implementation of the ACA. This research integrated three studies to understand changes in access and utilization of health care using t-test for descriptive analyses and multivariable logistic regressions to assess any differences post-ACA. Results showed lower odds of being uninsured (OR=0.52, p=0.000), delaying care (OR=0.72, p=0.000), and forgoing care (OR=0.71, p=0.000) post-ACA, for all groups. There were higher odds of having cholesterol (OR=1.33, p=0.000) and hypertension screenings (OR=1.32, p=0.000) after the ACA. Cancer screening results found slightly higher odds of obtaining a mammogram (OR=1.07, p=0.069) after the ACA, but lower odds of having a pap smear (OR=0.89, p=0.002) or colorectal cancer (OR=0.91, p=0.021) screening. Citizenship was a significant factor that influenced screening rates with non-citizen immigrants having the lowest screenings for all groups.
ASSESSING IMPACT OF CANCER AND DEPRESSION ON THE FINANCIAL HEALTH OF MIDDLE AGED AND OLDER AMERICANS
(2023) Omeaku, Nina; Boudreaux, Michel; Health Services Administration; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
This dissertation examines the impact of cancer on financial outcomes for individuals aged 50 and older and documents how this relationship varies by sex and race/ethnicity. I then turn to the impact of depression on out-of-pocket medical spending among those with a history of cancer. Findings suggest cancer can have a deleterious effect on the financial outcomes of those who are diagnosed with cancer. Out-of-pocket spending rises in the year of diagnosis, reduced earnings persist beyond diagnosis, and depression increases out-of-pocket spending. I fail to find evidence that the relationship between cancer and financial outcomes is moderated by sex or race-ethnicity.
ASSESSING THE IMPACT OF POLYPHARMACY ON THE ELDERLY USING NATIONALLY REPRESENTATIVE SURVEY DATA
(2023) Eschenlauer, Adam; Franzini, Luisa; Health Services Administration; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Background: Polypharmacy is a growing issue that affects individuals of all ages yet is most prevalent among patients aged 65 and older with chronic comorbidities. Although integral to most treatment plans, pharmaceutical intervention may negatively impact one’s health when five or more medications are taken daily. Given the concurrent rise in elderly population and polypharmacy prevalence, it is vital that we better understand the impact that concomitant medication use has on this vulnerable segment of population.Purpose: This research examines the factors leading to polypharmacy among the elderly population and explores its various impacts on healthcare utilization. Data and Methods: This study uses Medical Expenditure Panel Survey (MEPS) Data. Fixed-Effects regression analyses examine relationships between predictive factors and polypharmacy, polypharmacy and expenditures, and polypharmacy and utilization. Classification models assess the ability of machine learning to correctly predict utilization within the sample population. Key Results: Aside from clinical indicators, demographic and socio-economic factors play a role in determining polypharmacy status. Polypharmacy risk is higher for women (1.088, p < 0.001), high income individuals (1.107, p < 0.01), and those covered by Medicaid (1.110, p < 0.001). Conversely, married individuals (0.930, p < 0.001) and non-Hispanic Blacks (0.864, p < 0.001) have reduced risks of polypharmacy. We find polypharmacy to be associated with higher total (p < 0.001), inpatient (p < 0.01), outpatient (p < 0.01), and prescription medical expenditures (p < 0.001) when holding other predictors constant. We find the risk of hospitalization to be higher for polypharmacy patients (RR: 1.592, p < 0.001) than nonpolypharmacy patients after controlling for multimorbidity and medication class. Lastly, machine learning algorithms classify admissions with an overall accuracy of 84.9%; however, a low true positive rate (TPR) of 41.7% and high true negative rate (TNR) of 96.5% indicate best performance is achieved in predicting non-admissions. Conclusion: Polypharmacy is associated with several non-clinical factors and has a statistically significant impact on medical expenditures and admissions. Though imperfect, predictive analysis methods improve our ability to identify patients at risk for admissions and present a potential opportunity for future applications aimed at reducing utilization and costs.
BARRIERS OF AGING: THE IMPACT OF HOUSING ON U.S. OLDER ADULT HEALTH
(2020) Hall, Quinshay; Roby, Dylan H; Health Services Administration; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Today, millions of older adults aged 65 and older, face the challenges of aging. In the past ten years, the number of people aged 65 and older in the U.S. increased from 37.2 million to 49.2 million, and by 2040 an estimated one in five Americans will be age 65 or older (Administration for Community Living & Administration on Aging, 2018; Urban Institute, 2014). Housing is a significant factor in health outcomes for this population because of their increased time spent in the home, which can put them at an increased risk for home accidents (Newman, 2003). Using the Health and Retirement Study, this study explores the association of assistive features being present in one’s home on health status and provides evidence to identify the housing needs of the older adult population.

Changes in prenatal care and birth outcomes after federally qualified health center expansion
(Wiley, 2022-11-07) Gourevitch, Rebecca A.; Hatfield, Laura A.
Objective To evaluate whether the expansion of Federally Qualified Health Centers (FQHCs) improved late prenatal care initiation, low birth weight, and preterm birth among Medicaid-covered or uninsured individuals. Data Sources and Study Setting We identified all FQHCs in California using the Health Resources and Services Administration's Uniform Data System from 2000 to 2019. We used data from the U.S. Census American Community Survey to describe area characteristics. We measured outcomes in California birth certificate data from 2007 to 2019. Study Design We compared areas that received their first FQHC between 2011 and 2016 to areas that received it later or that had never had an FQHC. Specifically, we used a synthetic control with a staggered adoption approach to calculate non-parametric estimates of the average treatment effects on the treated areas. The key outcome variables were the rate of Medicaid or uninsured births with late prenatal care initiation (>3 months' gestation), with low birth weight (<2500 grams), or with preterm birth (<37 weeks' gestation). Data Collection/Extraction Methods The analysis was limited to births covered by Medicaid or that were uninsured, as indicated on the birth certificate. Principal Findings The 55 areas in California that received their first FQHC in 2011–2016 were more populous; their residents were more likely to be covered by Medicaid, to be low-income, or to be Hispanic than residents of the 48 areas that did not have an FQHC by the end of the study period. We found no statistically significant impact of the first FQHC on rates of late prenatal care initiation (ATT: −10.4 [95% CI −38.1, 15.0]), low birth weight (ATT: 0.2 [95% CI −7.1, 5.4]), or preterm birth (ATT: −7.0 [95% CI −15.5, 2.3]). Conclusions Our results from California suggest that access to primary and prenatal care may not be enough to improve these outcomes. Future work should evaluate the impact of ongoing initiatives to increase access to maternal health care at FQHCs through targeted workforce investments.
CHARACTERISTICS AND HEALTH INSURANCE COVERAGE AMONG ADOPTED CHILDREN IN THE UNITED STATES
(2024) Fleishman, Jamie Lin; Yue, Dahai; Health Services Administration; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
The practice of adopting a child is a common occurrence within the United States. Research on adoption, birth parents, and adoptive parents has traditionally focused on psychology and social work outcomes. This master’s thesis shifts the focus of adoption outcomes to a public health perspective, examining the demographics, socioeconomic conditions, and health insurance rates of domestic and international adoptees. To help determine the rates of any health insurance, public health insurance, and private health insurance, this thesis examined American Community Survey 2022 5-year data, a nationally representative study of adoptees and their counterparts—non-adoptees who are biologically related to their parents or head of household. It was determined that domestic adoptees and non-adoptees had similar demographic and socioeconomic statuses whereas international adoptees were predominantly non-Hispanic Asians, females, and have wealthier and White heads of households. After controlling for demographic and socioeconomic variables, it was discovered that international adoptees have higher uninsured rates compared to non-adoptees and domestic adoptees, which could be attributed to geographic differences in health insurance coverage. Further research is needed to examine health insurance coverage rates in the United States for adoptees.
Clinical Bioinformatics
(Philips Research, 2007-05) E. Z. Silfen
This article describes the emergence of the hybrid discipline of clinical bioinformatics. Specifically, it defines biomedical informatics as well as the four compositional domains of bioinformatics, imaging informatics, clinical informatics and public health informatics. Furthermore, it describes the relationship between bioinformatics, molecular medicine and clinical decision support, and offers a definition of clinical bioinformatics that arises from the integration of these domains. After establishing this background, the article discusses use cases for clinical bioinformatics, summarizes the field of clinical bioinformatics, and posits its potential for biomedicine research.
Community Living and Health Services Utilization among the Aging Services Network Population
(2017) Gaeta, Raphael; Simon-Rusinowitz, Lori; Chen, Jie; Health Services Administration; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
By 2050, the number of older adults will increase from 67 million to 111 million, or roughly 28 percent of the total U.S. population. Age is a principal predictor of physical health status as well as functional and cognitive limitation. As the aging population grows, so too will the demand for long-term services and supports (LTSS) and healthcare services. Despite this intersection, LTSS and healthcare systems are highly disconnected. The Aging Services Network, authorized and partially financed by the Older Americans Act (OAA), may play an important role in an emerging trend toward integrating services. Yet, OAA research is lacking. Existing OAA research faces several obstacles, including handling program variation resulting from a decentralized Aging Services Network, identifying non-user comparison groups for OAA study samples, and limited utility of national datasets. Studies often rely on highly descriptive methods, indirect comparisons to the general population of older adults, or state-restricted analysis. This dissertation addresses several gaps in the research. The first study aims to identify factors associated with community tenure and participation among low-income elderly living in subsidized housing. The research is grounded in conceptual frameworks from the World Health Organization. In-depth interviews and focus groups are used to explore these associations among elderly HUD building residents in Prince George's County, Maryland. The second study aims to identify multilevel predictors of OAA Title III services participation. This study develops a conceptual framework based on the Andersen Behavioral Model of Health Services Use, and uses a merged data set from the nationally representative Health and Retirement Study with geographic data and relevant state policies. The third study further examines the relationship between OAA Title III services participation and patterns of healthcare utilization. This dissertation research provides evidence for the importance of OAA Title III services, including for elderly HUD beneficiaries. Findings from multivariate regression analyses provide evidence for (1) county level targeting criteria used to measure LTSS need and direct OAA Title III funding, (2) substantial influence of Medicaid on access to OAA Title III services, and (3) changes in mix of health care services use among OAA Title III services participants over time.
Competition and Consolidation in Medicare Advantage
(2020) Chao, Sandra; DuGoff, Eva H.; Health Services Administration; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Background: Medicare Advantage (MA) serves roughly one in three (24 out of 68 million) Medicare beneficiaries and this number is expected to grow to about half (40 out of 80 million) of Medicare beneficiaries by 2030. Given this expected increase in demand for MA health plans, it is important to assess the relationship between market structure and benefit generosity to ensure that beneficiaries have equal access to high quality plans at low prices.Purpose: The purpose of this research is to assess how policy changes and market structures influence Medicare Advantage plan benefit designs. Data and Methods: This study uses publicly available MA data from the Centers for Medicare & Medicaid Services and the Area Health Resources File. Retrospective cross-sectional analyses examine contract consolidation and reconsolidation from 2012–2020, market competition and supplemental benefits in 2013, and market competition and maximum out-of-pocket limits in 2018. Key Results: Contract consolidations have declined in recent years, likely as a result of a policy that changed the calculation method of the star ratings among consolidated contracts. During the years that contract consolidations peaked, market concentration also increased. We find that the odds of a plan in a nonconcentrated market offering a transportation supplemental benefit is 2.8 times higher than a plan operating in a highly concentrated market, when holding all other predictors constant (p < 0.001). Similarly, plans in nonconcentrated service areas are 2.4 times more likely to offer a hearing benefit (p < 0.001) and 2.3 times more likely to offer a dental benefit (p < 0.001) than plans in highly concentrated markets. Regarding maximum out-of-pocket limits, we find that the odds of a plan in a highly concentrated market having a higher maximum limit is 1.6 times higher than a plan with a nonconcentrated market, when holding all other predictors constant (p = 0.049). Conclusion: MA contract consolidations have declined since 2016 but market concentration continues to increase. Market structure is important because we find that MA market concentration is associated with the offering of supplemental benefits and the level of maximum out-of-pocket limits.
Connecting the Dots Across the Care Continuum: Addressing Behavioral Health in ACO Networks
(2019) Anderson, Andrew; Franzini, Luisa; Health Services Administration; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Accountable Care Organizations (ACOs) represent a shift from traditional fee-for-service payment systems that reward volume to payment models that reward providers for value (e.g. quality improvement and cost reduction). Hospitals that lead or participate in ACOs have the potential to work with other providers to bridge the gap between traditional medical and behavioral health services. The goal of this dissertation was to examine the structures, processes, and outcomes of care for hospitals that lead or participate in ACO networks. The overarching hypothesis was that ACO-affiliated hospitals provide better behavioral health care due to increased care coordination and increased connections to behavioral health providers. This dissertation had three aims: 1) compare the implementation of care coordination strategies between ACO affiliated hospitals and unaffiliated hospitals and examine whether the implementation of care coordination strategies varies by hospital payment model types; 2) compare the use of care coordination strategies between ACO-affiliated hospitals with and without in-network behavioral health providers; and 3) compare rates of follow-up after a hospitalization for mental illness between ACO-affiliated and unaffiliated hospitals. These aims build on each other to illustrate how hospitals that participate in ACOs are improving care coordination and the provision of behavioral health services. There were several meaningful findings. ACO-affiliated hospitals were more likely to use care coordination strategies compared to unaffiliated hospitals. Participation in global capitation and shared savings models was associated with greater use of care coordination strategies. Nearly two-thirds of ACO-affiliated hospitals did not have in-network behavioral health providers. ACO-affiliated hospitals had a significantly higher average unadjusted rates of follow-up after a hospitalization for mental illness at 7 days and 30 days post-discharge compared to unaffiliated hospitals. Hospitals are important components of the care continuum and will play a critical role in improving outcomes for patients with behavioral health conditions. Policy makers should include behavioral health related performance measures tied to performance-based payment arrangements in ACO programs. ACOs can be used as way to bridge behavioral, clinical, and social services to address the unique needs of individuals with behavioral health conditions.
COVID-19 public health measures and patient and public involvement in health and social care research: An umbrella review
(International Journal of Environmental Research and Public Health, 2023-03-10) Fouladi, Negin; Tchangalova, Nedelina; Ajayi, Damilola; Millwee, Elizabeth; Lovett, Corinne; Del Sordi, Alana; Liggett, Samantha; De Silva, Malki; Bonilla, Laura; Nkwonta, Angel; Ramnarine, Leah; Munoz, Allyssa; Frazer, Kate; Kroll, Thillo
An umbrella review of previously published systematic reviews was conducted to determine the nature and extent of the patient and public involvement (PPI) in COVID-19 health and social care research and identify how PPI has been used to develop public health measures (PHM). In recent years, there has been a growing emphasis on PPI in research as it offers alternative perspectives and insight into the needs of healthcare users to improve the quality and relevance of research. In January 2022, nine databases were searched from 2020–2022, and records were filtered to identify peer-reviewed articles published in English. From a total of 1437 unique records, 54 full-text articles were initially evaluated, and six articles met the inclusion criteria. The included studies suggest that PHM should be attuned to communities within a sociocultural context. Based on the evidence included, it is evident that PPI in COVID-19-related research is varied. The existing evidence includes written feedback, conversations with stakeholders, and working groups/task forces. An inconsistent evidence base exists in the application and use of PPI in PHM. Successful mitigation efforts must be community specific while making PPI an integral component of shared decision-making.
Determinants of Unintended Pregnancy and Modern Family Planning Use
(2017) Kim, Theresa Youngjoo; Boudreaux, Michel H; Health Services Administration; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Unintended pregnancy, defined as a pregnancy that is mistimed or unwanted, is one of the world’s most common negative health outcomes. Furthermore, the United Nations Population Fund has found that 225 million women wish to delay or avoid pregnancy yet do not engage in modern family planning method use. Unintended pregnancy affects both maternal health (by way of nutrient deficiency, reproductive organ deficiency, and mental health) and child health (low birth weight, reduced gestational age, and nursing difficulties). The most life-saving and cost-saving means to prevent unintended pregnancy is to encourage modern family planning use. This dissertation examines family planning and unintended pregnancy in three different national contexts. In these studies, I: 1. Decompose the differences in unintended pregnancy rates for black and Hispanic women compared to white women in the United States; 2. Examine the relationship among indicators of health literacy, health system access, and utilization of modern family planning in Senegal; 3. Evaluate an intervention in Benin designed to increase modern family planning use. My research found that black and Hispanic women had a greater likelihood of unintended pregnancy compared to white women. However, psychosocial and socioeconomic factors contributed to the greater likelihoods of unintended pregnancy among racial and ethnic minorities. Among indicators of health literacy, oral and visual messages were the strongest predictors of health system access and modern family planning use in Senegal. The conclusion of the intervention in Benin found that social diffusion behaviors increased among people in the treatment group, and furthermore, the intervention did reduce unmet need for modern family planning use. These research results, though from different research studies, can imply that increasing access as much as possible to modern family planning use can ultimately prevent unintended pregnancy.
Differential associations of homelessness with emergencydepartment visits and hospitalizations by race, ethnicity, andgender
(Wiley, 2022-05-20) Yue, Dahai; Pourat, Nadereh; Essien, Elsie A.; Chen, Xiao; Zhou, Weihao; O'Masta, Brenna
Objective To investigate the differential associations of homelessness with emergency department (ED) visits and hospitalizations by race, ethnicity, and gender. Data Sources California Medicaid enrollment and claims. Study Design We identified beneficiaries experiencing homelessness (BEH) and those who did not (NBEH) using diagnosis and place of service codes and residential addresses. Outcomes include four ED visit measures and four hospitalization measures. We compared the use of these services by BEH to NBEH overall and by race, ethnicity, and gender groups in regression models controlling for covariates. Data Collection We used a sample of Medicaid beneficiaries who met eligibility criteria for a California Medicaid demonstration program in 2017 and 2018 but were not enrolled in the program. We identified 473,069 BEH, and the rest (1,948,422) were considered NBEH. We used the 2018 data for utilization analyses and most covariates. We constructed lagged measures of health conditions using 2017 data. Principal Findings We found that homelessness was significantly associated with 0.34 more ED visits (p < 0.01) and a higher likelihood of frequent ED visits (2.77 percentage points [pp], p < 0.01), any ED visits due to mental health conditions (0.79 pp, p < 0.01), and any ED visits due to substance use disorders (1.47 pp, p < 0.01). Experiencing homelessness was also significantly associated with 0.03 more hospitalizations (p < 0.01), a higher likelihood of frequent hospitalizations (0.68 pp, p < 0.01) and high frequent hospitalizations (0.28 pp, p < 0.01), and a longer length of stay (0.53 days, p < 0.01). We found a larger association for American Indian and Alaska Native, Black, Native Hawaii or Pacific Islander, and White populations than that for Asian and Hispanic populations. The associations are larger for males than females. Conclusions Our findings identified distinct utilization patterns by race, ethnicity, and gender. They indicated the need for developing race, ethnicity, and gender-specific strategies to reduce ED visits and hospitalizations of BEH.
DISPARITIES IN ADOLESCENT MENTAL HEALTH SERVICES UTILIZATION AND HELP-SEEKING
(2024) Truong, Michelle L; Sehgal, Neil J; Boudreaux, Michel; Health Services Administration; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Inequities in access to and utilization of mental and behavioral health care for adolescents have persisted for numerous decades. Adolescents from racial and ethnic minority backgrounds, as well as those in underserved geographic regions, are disproportionately impacted. As the youth mental health crisis escalates, it is critical to study the mechanisms driving these disparities to inform effective and targeted interventions and policies. Divided into three studies, this dissertation explored the influence of individual, cultural, and contextual factors on adolescent help-seeking behaviors using data from the 2009 and 2011 to 2019 California Health Interview Survey (CHIS).The first study employed mediation analyses to assess the extent to which having a subjective or perceived need for mental health care, conditional on objective need, contributes to racial and ethnic disparities in mental health services utilization. I found significant racial and ethnic differences in subjective needs for mental health services and that these differences partially explain the racial and ethnic disparities in service utilization. The second study explored differences in mental health service utilization among subgroups of non-Hispanic (NH) Asian and Latino/Hispanic adolescents compared to NH white adolescents. I found that Vietnamese and Mexican adolescents were significantly less likely to utilize mental health services relative to their NH white counterparts. The third study merged the adolescent data with provider data from the National Plan and Provider Enumeration System (NPPES), facility data from the National Substance Use and Mental Health Services Survey (N-SUMHSS), and population data from the US Decennial Census Redistricting Data Summary Files to assess the moderating effects of distance to the nearest pediatric mental health facility and provider-to-population densities on the relationship between subjective mental health care needs and service utilization. I discovered that provider density and subjective needs interact, resulting in a diminished effect of subjective needs on service utilization among adolescents residing in areas with lower primary care provider density. I did not find that distance to the nearest pediatric mental health facility had a significant impact on service utilization. This dissertation examined racial, ethnic, and geographic mental health care disparities among a diverse adolescent population in California. Findings from this work contribute to the understanding of adolescent help-seeking behaviors and provide insights for targeted interventions and policies to advance mental health care equity.
Distress and Deaths of Despair in the U.S. Healthcare Delivery System: Understanding Patterns in Healthcare among Distressed Americans
(2024) Spencer, Merianne Rose Tiglao; Chen, Jie; Health Services Administration; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
The United States has experienced rising mortality rates for the past several decades. Drug poisonings have increased nearly five-fold, suicide rates by nearly 40%, and by nearly 30% percent for alcohol-induced deaths between 1999 and 2021. This collection of drug-, alcohol- and suicide deaths are oftentimes referred to as “deaths of despair”, first coined by economists Anne Case and Angus Deaton who cited health and socioeconomic disparities driving Americans into mental distress, depression, and anxiety. The impact on the mental health of Americans was further exacerbated by the COVID-19 pandemic; this exposed vulnerabilities in the mental healthcare system as well as the various stressors that negatively impacted individuals across the globe. Using nationally representative data, this dissertation delves into the deaths of despair phenomenon using a multidisciplinary health services research lens. Access, utilization, and risk from deaths of despair are examined by using psychological distress (which is treated as a proxy for despair in the first two aims). Using the Kessler-6 scale, a well-accepted and clinically valid tool for non-specific mental distress, this dissertation explores patterns of healthcare spending among those with varying severity levels of psychological distress over a two-decade period; delves into patterns of healthcare utilization among young adults aged 18-30 (a population disproportionately impacted by stressors during the COVID-19 pandemic) by psychological distress; and quantifies the risk of death among those with varying severity levels of psychological distress.
