A national assessment of legacy versus new generation Medicaid data.
The purpose of the study was to review Medicaid legacy, Medicaid new generation, and Medicare claims across multiple states and compare performance on data analytic tasks. The researchers targeted the series of events that begins with a non-hospital-related medical emergency and ends with survival to discharge or death. Six data quality indicators were developed to evaluate the following: ambulance variables; code reporting for external cause of injury; linkage between claims; and death reporting on hospital discharge status codes. For death reporting on hospital discharge status codes the researchers estimated the severity of injuries and developed a model of its correlation with death in the Medicare population. The resulting model was utilized to compare reported versus expected deaths by level of injury severity in the Medicaid population. The study found that new generation Medicare claims had high performance across states and indicators, Medicaid legacy claims underperformed on multiple indicators in most states, and while new generation Medicaid claims outperformed Medicaid legacy claims on several indicators, conducting high-level analysis with that data will require substantial improvements.

Is bigger better?: A closer look at small health systems in the United States.
The purpose of this study was to expand existing health systems research by comparing the features, cost, and quality of care in small U.S. health care systems with those of large U.S. health systems. In this retrospective study with a repeated cross-sectional analysis, the researchers evaluated between 468 and 479 large health systems and between 608 and 641 small health systems serving fee-for-service Medicare beneficiaries, yearly between the year of 2013 and 2017. The study found that small systems had a larger share of beneficiaries and practice sites in small towns or rural areas, performance quality was lower in small systems that in large systems, and there was no difference in total cost of care. The study concluded that the quality of care in small systems is lower than large systems, but small systems provide care for rural Medicare populations. The researchers recommended that future research should explore the reasons for why these differences exist in quality.

Financial impacts of the Medicaid expansion on community health centers.
This study’s objective was to determine the impact of Medicaid expansion on community health centers. The authors combined data from the Uniform Data System, IRS nonprofit tax returns, and county-level characteristics from the Census Bureau. Their final dataset included 5841 center-year observations. They found a $2.08 million relative increase in Medicaid revenues, offset by a $0.44 million decrease in total grants among community health centers in expansion states compared with centers in non-expansion states. They found a large but not statistically significant $0.98 million relative increase in total expenditures among expansion state centers. Uncompensated care for health centers in expansion states decreased by $1.19 million relative to their counterparts in non-expansion states.

The Affordable Care Act Medicaid expansion: a difference-in-differences study of spillover participation in SNAP.
Medicaid expansion through the Affordable Care Act increased access to insurance coverage to adults under 138% of the federal poverty level and connected individuals to SNAP (the Supplemental Nutrition Assistance Food Program – formerly the Food Stamp Program). The purpose of this study was to estimate the effect of Medicaid expansion on SNAP participation among 414,000 individuals across the U.S. The study found that there was a 2.9% increase in SNAP participation produced by Medicaid expansion among individuals living under 138% of the federal poverty level. In subgroup analyses the researchers discovered a 5% increase in households without children below 75% of the federal poverty level, and an increase in SNAP households with zero dollars in income. The study concluded that the impact of the Medicaid expansion on access to SNAP participation was the greatest in very-low-income individuals, and that the impact of Medicaid expansion reaches beyond healthcare by increasing access to other supports like food which is a social determinant of health.

Associations among social needs, health and healthcare utilization, and desire for navigation services among US Medicaid beneficiaries with type 2 diabetes.
The purpose of this study was to determine the number and types of social needs experienced by Medicaid beneficiaries with type 2 diabetes and how these social needs are associated with key health indicators. Findings showed that having more social needs was associated with a wide range of indicators of poor health and well-being. Study participants with the greatest social need burden were most open to intervention.

Association of dual Medicare and Medicaid eligibility with outcomes and spending for cancer surgery in high-quality hospitals.
The purpose of this study was to assess whether treatment at high-quality hospitals mitigates dual-eligibility-associated disparities in outcomes and spending for cancer surgery. Medicare beneficiaries 65 years or older who underwent colectomy, rectal resection, lung resection, or pancreatectomy were evaluated. The findings indicate that, even among the highest-quality hospitals, dual-eligibility patients had poorer outcomes and higher spending. Dually eligible patients were more likely to be discharged to a facility and thus incurred higher post-acute care costs. Although treatment at high-quality hospitals is associated with reduced differences in outcomes, dual-eligibility patients remain at high risk for adverse post-operative outcomes as well as increased readmissions and post-acute care use.

Brief report: Medicaid expansion and growth in the workforce for autism spectrum disorder.
This study examined the role that state Medicaid expansion has played in utilization of child psychiatrists, board-certified behavioral analysts (BCBAs) and pediatricians for children with autism spectrum disorder (ASD). Health workforce data from HRSA was used to examine workforce growth from 2008-2017. State Medicaid expansion was associated with a 9% increase in BCBAs per 100,000 children one year after enactment, and a 5% increase in child psychiatrists, but no association with growth in pediatrician utilization.

Design and implementation of the Pediatric Quality Measures Program 2.0.
This AHRQ-authored research discusses the design and implementation of the Pediatric Quality Measures Program (PQMP) 2.0. The PQMP was established in response to the Children’s Health Insurance Program Reauthorization Act of 2009. AHRQ and CMS awarded 6 grants to Centers of Excellence (COEs) and a contract to facilitate collaboration and learning across the COEs. The COEs partnered with stakeholders from multiple levels to field test real-world implementation and refinement of pediatric quality measures and quality improvement initiatives. A PQMP Learning Collaborative (PQMP-LC) consisting of AHRQ, CMS, the 6 COEs, and L&M Policy Research, LLC was created to complete literature reviews, conduct key informant interviews, and collect data to develop reports to address the Research Foci. It also aided with development of measure implementation and quality improvement toolkits; conceptualized an implementation science framework, analysis, and roadmap; and facilitated dissemination of learnings and products. The various products created are intended to support the uptake of PQMP measures and inform future pediatric measurement and improvement work.

Real-world considerations for implementing pediatric quality measures: insights from key stakeholders.
This AHRQ-authored paper describes key stakeholder insights focused on measure implementation and increasing the uptake of Pediatric Quality Measures (PQM). The PQMP Learning Collaborative conducted semistructured interviews with 9 key informants (KIs) presenting states, health plans, and other potential end users. The interviews focused on obtaining KIs’ perspectives on 6 research questions focused on assessing the feasibility and usability of PQM and strengthening the connection between measurement and improvement. The KIs uniformly acknowledged the complexity of the issues raised and pinpointed multiple unresolved issues.

Suicide typologies among Medicaid beneficiaries, North Carolina 2014-2017.
Only ½ of suicide decedents are diagnosed with a mental health condition; population-based screening strategies are needed to help identify people who are at risk of suicide, and it may be necessary for providers to consider patient life circumstances that may place them at a higher risk. The purpose of this study was to identify suicide typologies among suicide decedents and describe the alignment between medical diagnoses and life circumstances. Decedent demographics, stressful life events, perceived and diagnosed/ health issues, suicidal behavior, and suicide method contributed to the typologies. In 2020 the researchers linked North Carolina Medicaid data with data from the North Carolina Violent Death reporting System (NC-VDRS) to analyze suicide decedents from 2014-2017, aged 25-54 years of age. Researchers analyzed 6 indicators of life circumstances from Medicaid claims and 12 indicators from the NC-VDRS and developed separate models for men and women. The study found that 88.3% of the suicide decedents were White, with a median age of 41 years, and more than 70% had experienced a health care visit in the 90 days prior to suicide. The study concluded that almost one-half of suicide decedents have a typology characterized by a low probability of diagnosis of mental health issues. The authors report that screenings for suicide could be improved by using improved indicators of lived experience and mental health.

Association of Medicaid expansion under the Affordable Care Act with access to elective spine surgical care.
This study's goal was to evaluate the impact of Medicaid expansion under the Affordable Care Act on the volume and payer mix of elective spine surgery in the United States. The authors evaluated elective spinal surgeries performed in the U.S. from 2011 to 2016 and included 10 states with expanded Medicaid access and 4 states that did not. They identified 218,648 surgical procedures performed in 10 Medicaid expansion states and 118,693 procedures performed in 4 nonexpansion states. Medicaid expansion was associated with a 17% increase in mean hospital spine surgical volume and a 23% increase in Medicaid volume. Privately insured surgical volumes did not change significantly. This increase indicated improved access to care.

Eligibility for and enrollment in Medicaid among nonelderly adults after implementation of the Affordable Care Act.
The authors used simulation modeling to examine Medicaid eligibility and participation during 2014 to 2017. They found that more than one in five adults were Medicaid-eligible in expansion states, while about one in 30 adults were Medicaid-eligible in non-expansion states. Further, while eligibility rates differed substantially by expansion status, participation rates among Medicaid-eligible adults were similar in both sets of states, indicating that differences in eligibility, rather than in participation rates, explained differences in enrollment between expansion and non-expansion states during the study period.

Medicaid, health, and the moderating role of neighborhood characteristics.
The purpose of this study was to evaluate whether the characteristics of different neighborhoods have an impact on the interaction between local environment and the effect of health insurance on health. The researchers utilized existing data from the Oregon Health Insurance Experiment and combined it with new, expanded data on neighborhood characteristics to assess whether those characteristics impacted the relationship between getting health insurance and health outcomes. The study found that the multiple domains of neighborhood characteristics did not affect the correlation between insurance and health outcomes, and concluded that Medicaid expansions do not differ greatly in effectiveness across neighborhoods.

Primary care visits and ambulatory care sensitive diabetes hospitalizations among adult Alabama Medicaid beneficiaries.
This retrospective cohort study described patterns of care use for Alabama Medicaid adult beneficiaries with diabetes and the association of primary care utilization and ambulatory care sensitive (ACS) diabetes hospitalizations. Alabama Medicaid claims data from January 2010 to April 2018 for 52, 549 covered adults aged 19-64 with diabetes was analyzed. Individuals were categorized by demographics, comorbidities, and health care use. Characteristics of the cohort with and without ACS hospitalization was reported. One third of the cohort had at least one ACS diabetes hospitalization over the observed periods. Hospital users tended to have multiple ACS hospitalizations as well as more comorbidities and pharmaceutical and other types of care use than those with no ACS hospitalizations. Having a primary care visit in one year was significantly associated with a reduced likelihood of ACS hospitalization in the following year.

The impact of a population-based system of care intervention on enhanced prenatal care and service utilization among Medicaid-insured pregnant women.
Enhanced prenatal/postnatal care home visiting programs for Medicaid-insured women have significant positive impacts on care and health outcomes. However, enhanced prenatal care participation rates are typically low, enrolling <30% of eligible women. This study investigated the impacts of a population-based systems approach on timely enhanced prenatal care participation and other healthcare utilization. The investigators concluded that a population systems approach improved selected enhanced prenatal care participation and service utilization for Medicaid-insured women in a county population, those in practices with established clinical-community linkages, and Black women.

Assessing the relationship between well-care visit and emergency department utilization among adolescents and young adults.
This study investigated the association between adolescent and young adult (AYA) well-care visits and emergency department (ED) utilization. Vermont’s all-payer claims data for 2018 was used to evaluate visits for 49,089 AYAs (aged 12-21 years) with a health-care claim. Nearly half (49%) of AYAs who engaged with the health-care system did not have a well-care visit in 2018. Those AYAs had 24% greater odds of going to the ED at least once in 2018, controlling for age, sex, insurance type, and medical complexity. Late adolescents and young adults (aged 18-21) who did not attend a well-care visit had 47% greater odds of ED visits, middle adolescents (15-17 years) had 9% greater odds, and early adolescents (12-14 years) had 16% greater odds.

Disruptions to the patient-provider relationship and patient utilization and outcomes: evidence from Medicaid managed care.
The patient-provider relationship is considered a cornerstone to delivering high-value healthcare. However, in Medicaid managed care settings, disruptions to this relationship are disproportionately common. In this paper, the researcher evaluated the impact of a primary provider's exit from a Medicaid managed care plan on adult beneficiary healthcare utilization and outcomes.

Increasing Medicaid's stagnant asset test for people eligible for Medicare and Medicaid will help vulnerable seniors.
Researchers examined states' income and asset tests for full-benefit Medicaid during the period 2006-18 and examined how alternative asset tests would affect eligibility for community-dwelling Medicare beneficiaries ages sixty-five and older. They found that increasing asset limits would lessen restrictions on Medicaid eligibility that arise from stagnant asset tests, broadening eligibility for certain low-income Medicare beneficiaries and allowing them to retain higher, yet still modest, savings.

Trends in anticoagulation prescription spending among Medicare Part D and Medicaid beneficiaries between 2014 and 2019.
Researchers examined contemporary direct oral anticoagulant (DOAC) spending patterns within Medicare Part D and Medicaid between 2014 and 2019. They found that, although overall DOAC spending is increasing, DOAC use may be associated with lower downstream medical expenditures compared with warfarin stemming from decreased risk of major bleeding and stroke and reduced drug monitoring.

Welcome mats and on-ramps for older adults: the impact of the Affordable Care Act's Medicaid Expansions on Dual Enrollment in Medicare and Medicaid.
The authors examined whether Medicaid participation by low-income adults age 65 and up increased as a result of Medicaid expansions to working-age adults under the Affordable Care Act (ACA). Using American Community Survey data and state variation in ACA Medicaid expansions, they found that Medicaid expansions to working-age adults increased Medicaid participation among low-income older adults by 4.4 percent. They also found evidence of an “on-ramp” effect, which is an important mechanism behind welcome mat effects among some older adults.
