Eliminating health care inequities through strengthening access to care.

OBJECTIVE: To provide a research agenda and recommendations to address inequities in access to health care. DATA SOURCES AND STUDY SETTING: The Agency for Healthcare Research and Quality (AHRQ) organized a Health Equity Summit in July 2022 to evaluate what equity in access to health care means in the context of AHRQ's mission and health care delivery implementation portfolio. The findings are a result of this Summit, and subsequent convenings of experts on access and equity from academia, industry, and the government. STUDY DESIGN: Multi-stakeholder input from AHRQ's Health Equity Summit, author consensus on a framework and key knowledge gaps, and summary of evidence from the supporting literature in the context of the framework ensure comprehensive recommendations. DATA COLLECTION/EXTRACTION METHODS: Through a stakeholder-engaged process, themes were developed to conceptualize access with a lens toward health equity. A working group researched the most appropriate framework for access to care to classify limitations identified during the Summit and develop recommendations supported by research in the context of the framework. This strategy was intentional, as the literature on inequities in access to care may itself be biased. PRINCIPAL FINDINGS: The Levesque et al. framework, which incorporates multiple dimensions of access (approachability, acceptability, availability, accommodation, affordability, and appropriateness), is the backdrop for framing research priorities for AHRQ. However, addressing inequities in access cannot be done without considering the roles of racism and intersectionality. Recommendations include funding research that not only measures racism within health care but also tests burgeoning anti-racist practices (e.g., co-production, provider training, holistic review, discrimination reporting, etc.), acting as a convener and thought leader in synthesizing best practices to mitigate racism, and forging the path forward for research on equity and access. CONCLUSIONS: AHRQ is well-positioned to develop an action plan, strategically fund it, and convene stakeholders across the health care spectrum to employ these recommendations.

Societal Costs and Outcomes of Medical and Recreational Marijuana Policies in the United States: A Systematic Review.

Significant support exists in the United States for legalization of marijuana/cannabis. As of 2021, 36 states and four territories approved the legalization of medical cannabis via medical marijuana laws (MMLs), and 15 states and District of Columbia (DC) have adopted recreational marijuana laws (RMLs). We performed structured and systematic searches of articles published from 2010 through September 2021. We assess the literature pertaining to adolescent marijuana use; opioid use and opioid-related outcomes; alcohol use; tobacco use; illicit and other drug use; marijuana growing and cultivation; employment, earnings, and other workplace outcomes; academic achievement and performance; criminal activity; perceived harmfulness; traffic and road safety; and suicide and sexual activity. Overall, 113 articles satisfied our inclusion criteria. Except for opioids, studies on use of other substances (illicit drugs, tobacco, and alcohol) were inconclusive. MMLs and RMLs do not generate negative outcomes in the labor market, lead to greater criminal activity, or reduce traffic and road safety.

Trends in Health Care Utilization and Expenditures in the United States Across 5 Decades: 1977-2017.

BACKGROUND: Health care expenditures in the United States are high and rising, with significant increases over the decades. The delivery, organization, and financing of the health care system has evolved over time due to technological innovation, policy changes, patient preferences, altering payment mechanisms, shifting demographics, and other factors. OBJECTIVE: The objective of this study was to examine trends over time in health care utilization and expenditures in the United States. RESEARCH DESIGN: This analysis employs descriptive statistics to examine 5 decades of health care utilization and expenditure data from the Agency for Healthcare Research and Quality (AHRQ) for 1977-2017. MEASURES: Measures include utilization and expenditures (not charges) for inpatient, emergency department, outpatient physician, outpatient nonphysician, office-based physician, dental, and out-of-pocket retail prescription drugs. RESULTS: We demonstrate that while health care expenditures have increased significantly overall and by type of care, utilization trends are less pronounced. The population of the United States grew 53% between 1977 and 2017, while annual total expenditures on health care increased by 208%. Amidst attention to out-of-pocket exposure for unexpected medical care bills, out-of-pocket payments for care have declined from 32% in 1977 to 12% in 2017 but increased in amount. CONCLUSIONS: This article provides the first extended snapshot of the dynamics of health care utilization and expenditures in the United States. Aspects of health care are much different today than in previous decades, yet the inpatient setting still dominates the expenditures.

Food insecurity, health care utilization, and health care expenditures.

OBJECTIVE: To disentangle the relationships among food insecurity, health care utilization, and health care expenditures. DATA SOURCES/STUDY SETTING: We use national data on 13 465 adults (age ≥ 18) from the 2016 Medical Expenditure Panel Survey (MEPS), the first year of the food insecurity measures. STUDY DESIGN: We employ two-stage empirical models (probit for any health care use/expenditure, ordinary least squares, and generalized linear models for amount of utilization/expenditure), controlling for demographics, health insurance, poverty status, chronic conditions, and other predictors. PRINCIPAL FINDINGS: Our results show that the likelihood of any health care expenditure (total, inpatient, emergency department, outpatient, and pharmaceutical) is higher for marginal, low, and very low food secure individuals. Relative to food secure households, very low food secure households are 5.1 percentage points (P < .001) more likely to have any health care expenditure, and have total health care expenditures that are 24.8 percent higher (P = .011). However, once we include chronic conditions in the models (ie, high blood pressure, heart disease, stroke, emphysema, high cholesterol, cancer, diabetes, arthritis, and asthma), these underlying health conditions mitigate the differences in expenditures by food insecurity status (only the likelihood of any having any health care expenditure for very low food secure households remains statistically significant). CONCLUSIONS: Policy makers and government agencies are focused on addressing deficiencies in social determinants of health and the resulting impacts on health status and health care utilization. Our results indicate that chronic conditions are strongly associated with food insecurity and higher health care spending. Efforts to alleviate food insecurity should consider the dual burden of chronic conditions. Finally, future research can address specific mechanisms underlying the relationships between food security, health, and health care.

Variation of preventive service utilization by state Medicaid coverage, cost-sharing, and Medicaid expansion status.

Preventive services can help reduce costs associated with chronic conditions. Medicaid beneficiaries have high rates of chronic conditions, but state Medicaid coverage and cost-sharing of preventive services varies widely. States that chose to expand Medicaid under the ACA were incentivized to cover recommended preventive services at no cost-sharing. This study evaluates whether state Medicaid policy and Medicaid expansion were associated with overall utilization, and disparities in utilization of preventive services among vulnerable populations. We used Medicaid policy data from Kaiser Family Foundation and MEPS data (2009-2014, n = 15,610), collected and analyzed in 2017. We used multivariable logistic regression, difference-in-differences, and difference-in-difference-in-differences models to examine the association between state Medicaid preventive service policy and Medicaid expansion on overall utilization, and disparities in utilization among race/ethnicity and income groups for blood pressure check, cholesterol screening, and flu shot. Medicaid coverage of flu shot was significantly associated with utilization (p < 0.001). Medicaid expansion significantly increased flu shot utilization among near-poor individuals (p < 0.01), Asians, and Latinos and blood pressure screening among African Americans (p < 0.05). For flu shot, the ACA is reaching its target audience: those in the coverage gap between Medicaid and private insurance. Increasing access to preventive services may not be enough to increase utilization, especially for vulnerable populations and/or the previously uninsured. Focusing on provider adherence to preventive service guidelines and education around who is eligible for what service and when could help increase utilization of preventive services in the future.

Medicaid Managed Care in Florida and Racial and Ethnic Disparities in Preventable Emergency Department Visits.

BACKGROUND: In an effort to address health care spending growth, coordinate care, and improve access to primary care in the Medicaid program, Florida implemented the Statewide Mandatory Managed Care (SMMC) program in May of 2014. OBJECTIVES: The objective of this study is to investigate the impact of implementation of mandatory managed care in Medicaid on the preventable emergency department (ED) utilizations, with a focus on racial/ethnic minorities. RESEARCH DESIGN: The primary data source is the universe of Florida ED visit and inpatient discharge data from 2010 to 2015, maintained by the Florida Agency for Health Care Administration. We adopt the New York University Billing's ED Classification Algorithm to create measures for preventable ED visits. Using difference-in-differences estimation, we examine preventable ED visits for Florida residents aged 18-64 with a primary payer of Medicaid (treatment group) and private health insurance (control group) pre-SMMC and post-SMMC reform. RESULTS: Our findings show that SMMC is statistically significantly associated with more reductions in preventable ED visits among non-Hispanic African American (incidence rate ratio=0.81; 95% confidence interval, 0.70-0.94) and Hispanic (incidence rate ratio=0.72; 95% CI, 0.60-0.87) Medicaid enrollees relative to their white counterparts. We also find significant reduction of racial/ethnic disparities only in counties with above median preimplementation Medicaid managed care penetration rate. CONCLUSIONS: Our findings suggest that implementation of Medicaid mandatory managed care in Florida is associated with reduced racial/ethnic disparities in preventable ED visits.

Global budgets in Maryland: early evidence on revenues, expenses, and margins in regulated and unregulated services.

Maryland implemented one of the most aggressive payment innovations the nation has seen in several decades when it introduced global budgets in all its acute care hospitals in 2014. Prior to this, a pilot program, total patient revenue (TPR), was established for 8 rural hospitals in 2010. Using financial hospital report data from the Health Services Cost Review Commission from 2007 to 2013, we examined the hospitals' financial results including revenue, costs, and profit/loss margins to explore the impact of the adoption of the TPR pilot global budget program relative to the remaining hospitals in the state. We analyze financial results for both regulated (included in the global budget and subject to rate-setting) and unregulated services in order to capture a holistic image of the hospitals' actual revenue, cost and margin structures. Common size and difference-in-differences analyses of the data suggest that regulated profit ratios for treatment hospitals increased (from 5% in 2007 to 8% in 2013) and regulated expense-to-gross patient revenue ratios decreased (75% in 2007 and 68% in 2013) relative to the controls. Simultaneously, the profit margins for treatment hospitals' unregulated services decreased (- 12% in 2007 and - 17% in 2013), which reduced the overall margin significantly. This analysis therefore indicates cost shifting and less profit gain from the program than identified by solely focusing on the regulated margins.

Mandatory Statewide Medicaid Managed Care in Florida and Hospitalizations for Ambulatory Care Sensitive Conditions.

OBJECTIVE: To investigate the impact of implementation of the Statewide Medicaid Managed Care (SMMC) program in Florida on access to and quality of primary care for Medicaid enrollees, measured by hospitalizations for ambulatory care sensitive conditions (ACSCs). DATA SOURCES: We examine inpatient data obtained from the Agency for Health Care Administration for 285 hospitals in Florida from January 2010 to June 2015. The analysis includes 3,645,515 discharges for Florida residents between the ages 18 and 64 with a primary payer of Medicaid or private insurance. STUDY DESIGN: We use a difference-in-differences approach, comparing the change in the incidence of ACSC-related inpatient visits among Medicaid patients before and after the implementation of SMMC, relative to the change among the privately insured. PRINCIPAL FINDINGS: After implementation of SMMC, Medicaid patients experienced a 0.35 percentage point slower growth in overall ACSC-related inpatient visits, and a 0.21 percentage point slower growth in chronic ACSC-related inpatient visits. The effects were significant in counties with above median Medicaid managed care penetration rates. CONCLUSIONS: Implementing mandatory managed care in Medicaid in Florida leads to slower growth in inpatient visits for conditions that can potentially be prevented with improved access to outpatient care.

Local Health Departments' Promotion of Mental Health Care and Reductions in 30-Day All-Cause Readmission Rates in Maryland.

BACKGROUND: Individuals affected with mental health conditions, including mood disorders and substance abuse, are at an increased risk of hospital readmission. OBJECTIVES: The objective of this study is to examine whether local health departments' (LHDs) active roles of promoting mental health are associated with reductions in 30-day all-cause readmission rates, a common quality metric. METHODS: Using datasets linked from multiple sources, including 2012-2013 State Inpatient Databases for the State of Maryland, the National Association of County and City Health Officials Profiles Survey, the Area Health Resource File, and US Census data, we employed multivariate logistic models to examine whether LHDs' active provision of mental health preventive care, mental health services, and health promotion were associated with the likelihood of having any 30-day all-cause readmission. RESULTS: Multivariate logistic regressions showed that LHDs' provision of mental health preventive care, mental health services, and health promotion were negatively associated with the likelihoods of having any 30-day readmission for adults 18-64 years old (odds ratios=0.71-0.82, P<0.001), and adults 65 and above (odds ratios=0.61-0.63, P<0.001, preventive care and services, respectively). These estimated associations were more prominent among individuals with mental illness and/or substance use disorders, African Americans, Medicare, and Medicaid enrollees. CONCLUSIONS: Our results suggest that LHDs in Maryland that engage in mental health prevention, promotion, and coordination activities are associated with benefits for residents and for the health care system at large. Additional research is needed to evaluate LHD activities in other states to determine if these results are generalizable.

The ACA's Dependent Coverage Expansion and Out-of-Pocket Spending by Young Adults With Behavioral Health Conditions.

OBJECTIVE: Young adults with behavioral health conditions (mental or substance use disorders) often lack access to care. In 2010, the Affordable Care Act (ACA) extended eligibility for dependent coverage under private health insurance, allowing young adults to continue on family plans until age 26. The objective of this study was to analyze out-of-pocket (OOP) spending as a share of total health care expenditures for young adults with behavioral health conditions before and after the implementation of the ACA dependent care provision. The study examined the population of young adults with behavioral health conditions overall and by race and ethnicity. METHODS: The study analyzed 2008-2009 and 2011-2012 nationally representative data from the Medical Expenditure Panel Survey with zero-or-one inflated beta regression models in a difference-in-differences framework to estimate the impact of the ACA's dependent coverage expansion. OOP spending was examined as a share of total health care expenditures among young adults with behavioral health disorders. The study compared the treatment group of individuals ages 19-25 (unweighted N=1,158) with a group ages 27-29 (unweighted N=668). RESULTS: Young adults ages 19-25 with behavioral health disorders were significantly less likely than the older group to have high levels of OOP spending after the implementation of the ACA's dependent coverage expansion. The reduction was pronounced among young adults from racial-ethnic minority groups. CONCLUSIONS: The extension of health insurance coverage to young adults with behavioral health disorders has provided them with additional financial protection, which can be important given the low incomes and high debt burden that characterize the age group.

Racial and Ethnic Disparities in Health Care Access and Utilization Under the Affordable Care Act.

OBJECTIVE: To examine racial and ethnic disparities in health care access and utilization after the Affordable Care Act (ACA) health insurance mandate was fully implemented in 2014. RESEARCH DESIGN: Using the 2011-2014 National Health Interview Survey, we examine changes in health care access and utilization for the nonelderly US adult population. Multivariate linear probability models are estimated to adjust for demographic and sociodemographic factors. RESULTS: The implementation of the ACA (year indicator 2014) is associated with significant reductions in the probabilities of being uninsured (coef=-0.03, P<0.001), delaying any necessary care (coef=-0.03, P<0.001), forgoing any necessary care (coef=-0.02, P<0.001), and a significant increase in the probability of having any physician visits (coef=0.02, P<0.001), compared with the reference year 2011. Interaction terms between the 2014 year indicator and race/ethnicity demonstrate that uninsured rates decreased more substantially among non-Latino African Americans (African Americans) (coef=-0.04, P<0.001) and Latinos (coef=-0.03, P<0.001) compared with non-Latino whites (whites). Latinos were less likely than whites to delay (coef=-0.02, P<0.001) or forgo (coef=-0.02, P<0.001) any necessary care and were more likely to have physician visits (coef=0.03, P<0.005) in 2014. The association between year indicator of 2014 and the probability of having any emergency department visits is not significant. CONCLUSIONS: Health care access and insurance coverage are major factors that contributed to racial and ethnic disparities before the ACA implementation. Our results demonstrate that racial and ethnic disparities in access have been reduced significantly during the initial years of the ACA implementation that expanded access and mandated that individuals obtain health insurance.

Linking uninsured patients treated in the emergency department to primary care shows some promise in Maryland.

Use of the emergency department (ED) has increased significantly over the past twenty years, especially among people who lack access to regular care, such as from a primary care provider. Not only are many ED visits avoidable, but receiving care through the ED also may disrupt continuity of care and result in increased overall health care costs. This article analyzes one of the twenty-nine local projects funded by the Centers for Medicare and Medicaid Services: the Emergency Department-Primary Care Connect initiative of the Primary Care Coalition of Montgomery County, Maryland. The initiative linked low-income or uninsured patients with local safety-net primary care providers. In the period 2009-11, five participating hospital EDs referred 10,761 low-income uninsured ED patients to four local primary care clinics. The intervention did not significantly reduce overall subsequent ED visits, but there was a significant reduction in subsequent ED visits among the subpopulation with chronic physical or behavioral conditions if they had more than two visits to the same primary care clinic. Our findings suggest that expansion of safety-net clinics, combined with strategies to link high-need patients in the ED with these primary care providers, can reduce subsequent ED use.

Access to primary and specialty care and emergency department utilization of medicaid enrollees needing specialty care.

OBJECTIVE: Medicaid enrollees are more likely to use the emergency department (ED) than the privately insured and uninsured, yet little is known about enrollees' problems in accessing primary care and specialty care providers among those needing specialty care. DATA SOURCES: The study sample is from the 2003-2010 Medical Expenditure Panel Survey (MEPS) of 2,733 Medicaid enrollees reporting a need for specialty care. METHODS: This paper estimates a two-part model to analyze the relationship between enrollees' access to providers and ED visits. PRINCIPAL FINDINGS: Perceived problems accessing a primary care physician are associated with ED use among Medicaid enrollees. Despite reporting need and facing barriers, access to specialty care is not significantly related to ED use. CONCLUSIONS: As states prepare for the impending expansion of Medicaid funded via the Affordable Care Act, they should address barriers to accessing primary care providers for Medicaid enrollees with high need.

Exploring contextual factors and patient activation: evidence from a nationally representative sample of patients with depression.

Patient activation has been considered as a "blockbuster drug of the century." Patients with mental disorders are less activated compared to patients with other chronic diseases. Low activation due to mental disorders can affect the efficiency of treatment of other comorbidities. Contextual factors are significantly associated with mental health care access and utilization. However, evidence of their association with patient activation is still lacking. Using data from the Health Tracking Household Survey 2007 and Area Health Resource File 2008, we examine the association between contextual factors and self-reported activation levels among patients with depression. We investigate two types of contextual factors--(a) site of usual source of care and (b) community characteristics, measured by mental health care resources availability, population demographics, and socioeconomic characteristics at the county level. Results show significant variation in activation levels by contextual factors. The availability of community mental health centers, lower proportion of foreign-born individuals, and higher income in the local community are associated with higher patient activation. Our results also show that depressed patients having a usual source of care at a physician's office have significantly higher patient activation levels than those with a usual source of care in the emergency department or hospital outpatient clinics. Results suggest that primary care setting is critical to having a sustained relationship between patients and physicians in order to enhance patient engagement in mental health care. Interventions in communities with low income and high immigrant populations are necessary.

Medicaid primary care physician fees and the use of preventive services among Medicaid enrollees.

OBJECTIVE: The Patient Protection and Affordable Care Act (ACA) increases Medicaid physician fees for preventive care up to Medicare rates for 2013 and 2014. The purpose of this paper was to model the relationship between Medicaid preventive care payment rates and the use of U.S. Preventive Services Task Force (USPSTF)-recommended preventive care use among Medicaid enrollees. DATA SOURCES/STUDY SESSION: We used data from the 2003 and 2008 Medical Expenditure Panel Survey (MEPS), a national probability sample of the U.S. civilian, noninstitutionalized population, linked to Kaiser state Medicaid benefits data, including the state Medicaid-to-Medicare physician fee ratio in 2003 and 2008. STUDY DESIGN: Probit models were used to estimate the probability that eligible individuals received one of five USPSF-recommended preventive services. A difference-in-difference model was used to separate out the effect of changes in the Medicaid payment rate and other factors. DATA COLLECTION/EXTRACTION METHODS: Data were linked using state identifiers. PRINCIPAL FINDINGS: Although Medicaid enrollees had a lower rate of use of the five preventive services in univariate analysis, neither Medicaid enrollment nor changes in Medicaid payment rates had statistically significant effects on meeting screening recommendations for the five screenings. The results were robust to a number of different sensitivity tests. Individual and state characteristics were significant. CONCLUSIONS: Our results suggest that although temporary changes in primary care provider payments for preventive services for Medicaid enrollees may have other desirable effects, they are unlikely to substantially increase the use of these selected USPSTF-recommended preventive care services among Medicaid enrollees.

Using quantile regression to examine health care expenditures during the Great Recession.

OBJECTIVE: To examine the association between the Great Recession of 2007-2009 and health care expenditures along the health care spending distribution, with a focus on racial/ethnic disparities. DATA SOURCES/STUDY SETTING: Secondary data analyses of the Medical Expenditure Panel Survey (2005-2006 and 2008-2009). STUDY DESIGN: Quantile multivariate regressions are employed to measure the different associations between the economic recession of 2007-2009 and health care spending. Race/ethnicity and interaction terms between race/ethnicity and a recession indicator are controlled to examine whether minorities encountered disproportionately lower health spending during the economic recession. PRINCIPAL FINDINGS: The Great Recession was significantly associated with reductions in health care expenditures at the 10th-50th percentiles of the distribution, but not at the 75th-90th percentiles. Racial and ethnic disparities were more substantial at the lower end of the health expenditure distribution; however, on average the reduction in expenditures was similar for all race/ethnic groups. The Great Recession was also positively associated with spending on emergency department visits. CONCLUSION: This study shows that the relationship between the Great Recession and health care spending varied along the health expenditure distribution. More variability was observed in the lower end of the health spending distribution compared to the higher end.

Decomposing the gap in satisfaction with provider communication between English- and Spanish-speaking Hispanic patients.

Disparities in patient-provider communication exist among racial/ethnic groups. Hispanics report the lowest satisfaction with provider communication compared to whites and blacks; these differences may be due to level of acculturation or patient-provider concordance according to their ability to speak English. Using data from the 2007-2009 Medical Expenditure Panel Survey, this study identifies and quantifies the components that constitute the gap in satisfaction with provider communication between English- and Spanish-speaking Hispanics. English-speaking Hispanics are 7.3 percentage points more likely to be satisfied with the amount of time their providers spent with them compared to Spanish-speaking Hispanics. Differences in acculturation between the two groups account for 77% of this gap. Satisfaction with provider listening is 6.8 percentage points higher for English-speaking Hispanics. Hispanics who speak English are more satisfied with provider communication. The gap in satisfaction is largely attributable to differences in health insurance, acculturation, and education.

Nonemergent emergency department use among patients with a usual source of care.

PURPOSE: Emergency department (ED) use for nonemergent conditions is associated with discontinuity of care at a greater cost. The objective of this study was to determine whether the quality of patient-provider communication and access to one's usual source of care (USC) were associated with greater nonemergent ED use. METHODS: A hurdle model was employed using data from the 2007 to 2009 Medical Expenditure Panel Survey. First, a multivariate logistic regression model was used to identify factors associated with the likelihood of a nonemergent ED visit. Given that one occurrence exists, a second negative binomial model was used to establish whether patient-provider communication or access are related to the frequency of nonemergent ED use. RESULTS: One element of communication, patient-provider language concordance, is associated with fewer nonemergent ED visits (P < .05). Several aspects of access are related to reduced ED use for nonemergent purposes. Patients whose USC is available after hours and those who travel less than an hour to get to their USC use the ED less for nonemergent care (P ≤ .05). CONCLUSIONS: Enhancing primary care by expanding interpreter services and access to care after hours may reduce the demand for nonemergent ED services.
