Chronic Health Outcomes and Prescription Drug Copayments in Medicaid.

BACKGROUND: Prescription drug copayments and cost-sharing have been linked to reductions in prescription drug use and expenditures. However, little is known about their effect on specific health outcomes. OBJECTIVE: To evaluate the association between prescription drug copayments and uncontrolled hypertension, uncontrolled hypercholesterolemia, and prescription drug utilization among Medicaid beneficiaries with these conditions. SUBJECTS: Select adults aged 20-64 from NHANES 1999-2012 in 18 states. MEASURES: Uncontrolled hypertension, uncontrolled hypercholesterolemia, and taking medication for each of these conditions. RESEARCH DESIGN: A differencing regression model was used to evaluate health outcomes among Medicaid beneficiaries in 4 states that introduced copayments during the study period, relative to 2 comparison groups-Medicaid beneficiaries in 14 states unaffected by shifts in copayment policy, and a within-state counterfactual group of low-income adults not on Medicaid, while controlling for individual demographic factors and unobserved state-level characteristics. RESULTS: Although uncontrolled hypertension and hypercholesterolemia declined among all low-income persons during the study period, the trend was less pronounced in Medicaid beneficiaries affected by copayments. After netting out concurrent trends in health outcomes of low-income persons unaffected by Medicaid copayment changes, we estimated that introduction of drug copayments in Medicaid was associated with an average rise in uncontrolled hypertension and uncontrolled hypercholesterolemia of 7.7 and 13.2 percentage points, respectively, and with reduced drug utilization for hypercholesterolemia. CONCLUSIONS: As Medicaid programs change in the years following the Affordable Care Act, prescription drug copayments may play a role as a lever for controlling hypertension and hypercholesterolemia at the population level.

Clinical Preventive Services Coverage and the Affordable Care Act.

The Affordable Care Act requires many health plans to provide coverage for certain recommended clinical preventive services without charging copays or deductible payments. This provision could lead to greater uptake of many services that can improve health and save lives. Although the coverage provision is broad, there are many caveats that also apply. It is important for providers and public health professionals to understand the nuances of the coverage rules to help maximize their potential to improve population health.

Receipt of Selected Clinical Preventive Services by Adults ­ United States, 2011-2012.

Preventive services are available for nine of the ten leading causes of death in the United States. The Affordable Care Act (ACA) has reduced cost as a barrier to care by expanding access to insurance and requiring many health plans to cover certain recommended preventive services without copayments or deductibles. To establish a baseline for the receipt of these services for monitoring the effects of the law after 2012, CDC analyzed responses from persons aged ≥18 years in the National Health Interview Survey (NHIS) for the years 2011 and 2012 combined. NHIS is an in-person interview administered annually to a nationally representative sample of the noninstitutionalized, U.S. civilian population. This report summarizes the findings for nine preventive services covered by the ACA. Having health insurance or a higher income was associated with higher rates of receiving these services, affirming findings of previous studies. Securing health insurance coverage might be an important way to increase receipt of clinical preventive services, but insurance coverage is not sufficient to ensure that everyone is offered or uses clinical services proven to prevent disease. Greater awareness of ACA provisions among the public, public health professionals, partners, and health care providers might help increase the receipt of recommended services.

Relationship of income and health care coverage to receipt of recommended clinical preventive services by adults - United States, 2011-2012.

Each year in the United States, an estimated 100,000 deaths could be prevented if persons received recommended clinical preventive care. The Affordable Care Act has reduced cost as a barrier to care by expanding access to insurance and requiring many health plans to cover certain recommended preventive services without copayments or deductibles. To establish a baseline for the receipt of these services and to begin monitoring the effects of the law, CDC analyzed responses from persons aged ≥18 years in the National Health Interview Survey (NHIS) for the years 2011 and 2012 combined. This report summarizes the findings for six services covered by the Affordable Care Act. Among the six services examined, three were received by less than half of the persons for whom they were recommended (testing for human immunodeficiency virus [HIV] and vaccination for influenza and zoster [shingles]). Having health insurance or a higher income was associated with higher rates of receiving these preventive services, affirming findings of previous studies. Securing health insurance coverage might be an important way to increase receipt of clinical preventive services, but insurance coverage is not all that is needed to ensure that everyone is offered and uses clinical services proven to prevent disease. Greater awareness of Affordable Care Act provisions among public health professionals, partners, health care providers, and patients might help increase the receipt of recommended services.

Cognitive ontologies for neuropsychiatric phenomics research.

Now that genome-wide association studies (GWAS) are dominating the landscape of genetic research on neuropsychiatric syndromes, investigators are being faced with complexity on an unprecedented scale. It is now clear that phenomics, the systematic study of phenotypes on a genome-wide scale, comprises a rate-limiting step on the road to genomic discovery. To gain traction on the myriad paths leading from genomic variation to syndromal manifestations, informatics strategies must be deployed to navigate increasingly broad domains of knowledge and help researchers find the most important signals. The success of the Gene Ontology project suggests the potential benefits of developing schemata to represent higher levels of phenotypic expression. Challenges in cognitive ontology development include the lack of formal definitions of key concepts and relations among entities, the inconsistent use of terminology across investigators and time, and the fact that relations among cognitive concepts are not likely to be well represented by simple hierarchical "tree" structures. Because cognitive concept labels are labile, there is a need to represent empirical findings at the cognitive test indicator level. This level of description has greater consistency, and benefits from operational definitions of its concepts and relations to quantitative data. Considering cognitive test indicators as the foundation of cognitive ontologies carries several implications, including the likely utility of cognitive task taxonomies. The concept of cognitive "test speciation" is introduced to mark the evolution of paradigms sufficiently unique that their results cannot be "mated" productively with others in meta-analysis. Several projects have been initiated to develop cognitive ontologies at the Consortium for Neuropsychiatric Phenomics (www.phenomics.ucla.edu), in the hope that these ultimately will enable more effective collaboration, and facilitate connections of information about cognitive phenotypes to other levels of biological knowledge. Several free web applications are available already to support examination and visualisation of cognitive concepts in the literature (PubGraph, PubAtlas, PubBrain) and to aid collaborative development of cognitive ontologies (Phenowiki and the Cognitive Atlas). It is hoped that these tools will help formalise inference about cognitive concepts in behavioural and neuroimaging studies, and facilitate discovery of the genetic bases of both healthy cognition and cognitive disorders.

Surveillance for Health Care Access and Health Services Use, Adults Aged 18-64 Years - Behavioral Risk Factor Surveillance System, United States, 2014.

PROBLEM/CONDITION: As a result of the 2010 Patient Protection and Affordable Care Act, millions of U.S. adults attained health insurance coverage. However, millions of adults remain uninsured or underinsured. Compared with adults without barriers to health care, adults who lack health insurance coverage, have coverage gaps, or skip or delay care because of limited personal finances might face increased risk for poor physical and mental health and premature mortality. PERIOD COVERED: 2014. DESCRIPTION OF SYSTEM: The Behavioral Risk Factor Surveillance System (BRFSS) is an ongoing, state-based, landline- and cellular-telephone survey of noninstitutionalized adults aged ≥18 years residing in the United States. Data are collected from states, the District of Columbia, and participating U.S. territories on health risk behaviors, chronic health conditions, health care access, and use of clinical preventive services (CPS). An optional Health Care Access module was included in the 2014 BRFSS. This report summarizes 2014 BRFSS data from all 50 states and the District of Columbia on health care access and use of selected CPS recommended by the U.S. Preventive Services Task Force or the Advisory Committee on Immunization Practices among working-aged adults (aged 18-64 years), by state, state Medicaid expansion status, expanded geographic region, and federal poverty level (FPL). This report also provides analysis of primary type of health insurance coverage at the time of interview, continuity of health insurance coverage during the preceding 12 months, and other health care access measures (i.e., unmet health care need because of cost, unmet prescription need because of cost, medical debt [medical bills being paid off over time], number of health care visits during the preceding year, and satisfaction with received health care) from 43 states that included questions from the optional BRFSS Health Care Access module. RESULTS: In 2014, health insurance coverage and other health care access measures varied substantially by state, state Medicaid expansion status, expanded geographic region (i.e., states categorized geographically into nine regions), and FPL category. The following proportions refer to the range of estimated prevalence for health insurance and other health care access measures by examined geographical unit (unless otherwise specified), as reported by respondents. Among adults with health insurance coverage, the range was 70.8%-94.5% for states, 78.8%-94.5% for Medicaid expansion states, 70.8%-89.1% for nonexpansion states, 73.3%-91.0% for expanded geographic regions, and 64.2%-95.8% for FPL categories. Among adults who had a usual source of health care, the range was 57.2%-86.6% for states, 57.2%-86.6% for Medicaid expansion states, 61.8%-83.9% for nonexpansion states, 64.4%-83.6% for expanded geographic regions, and 61.0%-81.6% for FPL categories. Among adults who received a routine checkup, the range was 52.1%-75.5% for states, 56.0%-75.5% for Medicaid expansion states, 52.1%-71.1% for nonexpansion states, 56.8%-70.2% for expanded geographic regions, and 59.9%-69.2% for FPL categories. Among adults who had unmet health care need because of cost, the range was 8.0%-23.1% for states, 8.0%-21.9% for Medicaid expansion states, 11.9%-23.1% for nonexpansion states, 11.6%-20.3% for expanded geographic regions, and 5.3%-32.9% for FPL categories. Estimated prevalence of cancer screenings, influenza vaccination, and having ever been tested for human immunodeficiency virus also varied by state, state Medicaid expansion status, expanded geographic region, and FPL category. The prevalence of insurance coverage varied by approximately 25 percentage points among racial/ethnic groups (range: 63.9% among Hispanics to 88.4% among non-Hispanic Asians) and by approximately 32 percentage points by FPL category (range: 64.2% among adults with household income <100% of FPL to 95.8% among adults with household income >400% of FPL). The prevalence of unmet health care need because of cost varied by nearly 14 percentage points among racial/ethnic groups (range: 11.3% among non-Hispanic Asians to 25.0% among Hispanics), by approximately 17 percentage points among adults with and without disabilities (30.8% versus 13.7%), and by approximately 28 percentage points by FPL category (range: 5.3% among adults with household income >400% of FPL to 32.9% among adults with household income <100% of FPL). Among the 43 states that included questions from the optional module, a majority of adults reported private health insurance coverage (63.4%), followed by public health plan coverage (19.4%) and no primary source of insurance (17.1%). Financial barriers to health care (unmet health care need because of cost, unmet prescribed medication need because of cost, and medical bills being paid off over time [medical debt]) were typically lower among adults in Medicaid expansion states than those in nonexpansion states regardless of source of insurance. Approximately 75.6% of adults reported being continuously insured during the preceding 12 months, 12.9% reported a gap in coverage, and 11.5% reported being uninsured during the preceding 12 months. The largest proportion of adults reported ≥3 visits to a health care professional during the preceding 12 months (47.3%), followed by 1-2 visits (37.1%), and no health care visits (15.6%). Adults in expansion and nonexpansion states reported similar levels of satisfaction with received health care by primary source of health insurance coverage and by continuity of health insurance coverage during the preceding 12 months. INTERPRETATION: This report presents for the first time estimates of population-based health care access and use of CPS among adults aged 18-64 years. The findings in this report indicate substantial variations in health insurance coverage; other health care access measures; and use of CPS by state, state Medicaid expansion status, expanded geographic region, and FPL category. In 2014, health insurance coverage, having a usual source of care, having a routine checkup, and not experiencing unmet health care need because of cost were higher among adults living below the poverty level (i.e., household income <100% of FPL) in states that expanded Medicaid than in states that did not. Similarly, estimates of breast and cervical cancer screening and influenza vaccination were higher among adults living below the poverty level in states that expanded Medicaid than in states that did not. These disparities might be due to larger differences to begin with, decreased disparities in Medicaid expansion states versus nonexpansion states, or increased disparities in nonexpansion states. PUBLIC HEALTH ACTION: BRFSS data from 2014 can be used as a baseline by which to assess and monitor changes that might occur after 2014 resulting from programs and policies designed to increase access to health care, reduce health disparities, and improve the health of the adult population. Post-2014 changes in health care access, such as source of health insurance coverage, attainment and continuity of coverage, financial barriers, preventive care services, and health outcomes, can be monitored using these baseline estimates.

Increasing Receipt of Women's Preventive Services.

The receipt of clinical preventive services is important for health promotion and prevention of illness, death, and disability for women in the United States. Today, the Affordable Care Act makes a variety of evidence-based preventive services available with no out-of-pocket cost to women with certain health insurance plans. Nevertheless, available service receipt data suggest receipt of the services for all American adults remains suboptimal. This article seeks to raise awareness about the critical gaps in the delivery of preventive services to women and highlight opportunities for women, primary care providers, and public health professionals to increase receipt of clinical preventive services among women.
