Medicaid expansion led to reductions in postpartum hospitalizations.
The purpose of this study was to assess whether the Medicaid expansions of the Affordable Care Act (ACA) affected rates of postpartum hospitalization. The researchers compared states that did and did not expand Medicaid under the ACA as they related to changes in hospitalizations among birthing people with a Medicaid-financed delivery. The study found a 17% reduction in hospitalizations during the first 60 days postpartum associated with the Medicaid expansions, and evidence of a lesser decrease in hospitalizations between 61 days and 6 months postpartum. The researchers concluded that Medicaid coverage expansion under the ACA resulted in improved postpartum health for low-income birthing people.

Racial and ethnic disparities in preventable hospitalizations and ED visits five years after ACA Medicaid expansions,.
This AHRQ-authored paper examined whether the 2014 Affordable Care Act (ACA) Medicaid expansions mitigated existing racial or ethnic disparities in preventable hospitalizations and emergency department (ED) visits. The authors used inpatient data from twenty-nine states and ED data from twenty-six states for the period 2011 to 2018. They found that Medicaid expansions decreased disparities in preventable hospitalizations and ED visits between non-Hispanic Black and White nonelderly adults by 10 percent or more. There were no significant effects on disparities between Hispanic and non-Hispanic White nonelderly adults. Their findings highlight sustained improvements in community-level care for non-Hispanic Black populations, but also suggest access barriers experienced by Hispanic adults that need to be addressed beyond Medicaid eligibility expansion.

Hospitalization rates among persons with HIV who gained Medicaid or private insurance after the Affordable Care Act in 2014.
The purpose of this study was to investigate whether gaining inpatient healthcare coverage had an effect on hospitalization rates among persons with HIV following implementation of the Affordable Care Act in 2014. Hospitalization data from 2015 were obtained on adults receiving longitudinal care at HIV clinics; all patients were previously uninsured and supported by the Ryan White HIV/AIDS Program (RWHAP) in 2013. Findings showed that acquiring inpatient coverage was not associated with a change in hospitalization rates.

Impact of Medicaid expansion on access and healthcare among individuals with sickle cell disease.
The purpose of this study was to examine whether Medicaid expansion in California, increased Medicaid enrollment, increased hydroxyurea prescriptions filled, and decreased acute healthcare utilization in sickle cell disease (SCD). Findings showed that Medicaid expansion did not appear to have improved enrollment or acute healthcare utilization among individuals with SCD in California. Recommendations included future studies exploring whether individuals with SCD transitioned to other insurance plans or became uninsured post-expansion, the underlying reasons for low hydroxyurea utilization, and the lack of effect on hospital admissions despite a modest effect on emergency department visits.

Social disadvantage, access to care, and disparities in physical functioning among children hospitalized with respiratory illness.
This study examined associations between social disadvantage, access to care, and disparities in physical functioning among children hospitalized with acute respiratory illness. The study cohort included children ages 8-16 years and/or caregivers of children 2 weeks to 16 years admitted to five tertiary care children’s hospitals for three common respiratory illnesses from July 2014 through June 2016. Surveys were completed within 2 to 8 weeks after discharge. The survey assessed social disadvantage, difficulty/delays accessing care, and baseline and follow-up health-related quality of life (HRQoL), and physical functioning using the Pediatric Quality of Life Inventory (PedsQL). A total of 1,325 patients and/or their caregivers completed both PedsQL surveys. Adjusted mean baseline PedsQL scores were significantly lower for patients with social disadvantage (minority race/ethnicity, limited English proficiency, low education, and low income), than for patients with none. There were also disadvantage markers or difficulty/delays accessing care which were associated with lower physical functioning. However, these differences were reduced after hospital discharge.

The relationship between violence in Northern Mexico and potentially avoidable hospitalizations in the USA-Mexico border region.
The authors quantified associations between violence in Mexico and decreases in access to care for border county residents. They found that increased homicide rates in Mexico were associated with increased hospitalizations for ambulatory care sensitive (ACS) conditions in the USA, although residence in a border county was associated with decreased probability of being hospitalized for an ACS condition.

A patient navigation intervention for drug-involved former prison inmates.
The researchers designed a randomized controlled trial of patient navigation to reduce barriers to health care and hospitalizations for former prison inmates. They found recruitment of former inmates highly feasible, but found that follow-up was limited by rearrests. They concluded that their results suggest a significantly lower rate of hospitalizations among navigation participants, although the rate of emergency department/urgent care visits was not improved.

Has access to care changed in minority communities? A study of preventable hospitalizations over time in selected States.
Basu assessed the changes in access to care in minority communities by examining the association between preventable hospitalization rates and racial/ethnic composition of the community during 1995-2005. Using HCUP data, the results indicated increases in barriers faced by minority adults in accessing primary care over time, with no similar evidence for the elderly subgroup.

The small area predictors of ambulatory care sensitive hospitalizations: a comparison of changes over time.
The investigators examined the predictors of ambulatory care sensitive conditions (ACSCs) admissions in small geographic areas in two cross-sections spanning an 11-year time interval (1995-2005). They found that ACSC admission rates were inversely related to the availability of local primary care physicians, and managed care was associated with declines in ACSC admissions for the elderly. Additionally, minorities, aged elderly, and percent under federal poverty level were found to be associated with higher ACSC rates. They concluded that improvements in socioeconomic conditions and geographic access may have helped improve the quality of primary care received by the elderly over the last decade, particularly among some minority groups.
