US Hospital Service Availability and New 340B Program Participation.

Importance: The US 340B Drug Pricing Program enables eligible hospitals to receive substantial discounts on outpatient drugs to improve hospitals' financial sustainability and maintain access to care for patients who have low income and/or are uninsured. However, it is unclear whether hospitals use program savings to subsidize access as intended.

Objective: To evaluate whether the 340B program is associated with improvements in access to hospital-based services and to test whether the association varies by hospital ownership.

Building Data Infrastructure for Disease-Focused Health Economics Research.

Background: Data infrastructure for cancer research is centered on registries that are often augmented with payer or hospital discharge databases, but these linkages are limited. A recent alternative in some states is to augment registry data with All-Payer Claims Databases (APCDs). These linkages capture patient-centered economic outcomes, including those driven by insurance and influence health equity, and can serve as a prototype for health economics research.

Treatment Disparities in Radiation and Hormone Therapy Among Women Covered by Medicaid vs Private Insurance in Cancer Registry and Claims Data.

Importance: Prior research has reported undertreatment among patients with cancer who are insured by Medicaid, but this finding may be due, in part, to incomplete data in cancer registries.

Objective: To compare disparities in radiation and hormone therapy between women with breast cancer covered by Medicaid and those with private insurance using the Colorado Central Cancer Registry (CCCR) and CCCR data supplemented with All Payer Claims Data (APCD).

Design, Setting, And Participants: This observational cohort study included women aged 21 to 63 years who received breast cancer surgery.

Medicaid Payment For Postpartum Long-Acting Reversible Contraception Prompts More Equitable Use.

To increase access to highly effective contraception and improve reproductive autonomy, a growing number of state Medicaid programs pay for the provision of immediate postpartum long-acting reversible contraception (LARC) in addition to providing a global payment for maternity care. Using Pregnancy Risk Assessment Monitoring System data, we examined postpartum LARC use both overall and by race and ethnicity among respondents with Medicaid-paid births during the period 2012-18 in eight states that implemented immediate postpartum LARC payment and eight states without it. Using a quasi-experimental difference-in-differences design, we found that the policy resulted in an overall 2.

Understanding the relationship between nonprofit hospital community benefit spending and system membership: An analysis of independent hospital acquisitions.

The Internal Revenue Service (IRS) requires nonprofit hospitals to report community benefit spending to justify their nonprofit tax exemption. We examined whether nonprofit hospital acquisitions influence the amount and type community benefit spending. We analyzed 2011-2018 data on urban, nonprofit hospitals.

Cancer Treatment Data in Central Cancer Registries: When Are Supplemental Data Needed?

Background: We evaluated treatment concordance between the Colorado All Payer Claims Database (APCD) and the Colorado Central Cancer Registry (CCCR) to explore whether APCDs can augment registry data. We compare treatment concordance for breast cancer, an extensively studied site with an inpatient reporting source and select leukemias that are often diagnosed outpatient.

Methods: We analyzed concordance by cancer type and treatment, patient demographics, reporting source, and health insurance, calculating the sensitivity, specificity, positive predictive values (PPV) and Kappa statistics.

Capitalizing on Central Registries for Expanded Cancer Surveillance and Research.

Background: State central cancer registries are an essential component of cancer surveillance and research that can be enriched through linkages to other databases. This study identified and described state central registry linkages to external data sources and assessed the potential for a more comprehensive data infrastructure with registries at its core.

Methods: We identified peer-reviewed papers describing linkages to state central cancer registries in all 50 states, Washington, DC, and Puerto Rico, published between 2010 and 2020.

The role of all-payer claims databases to expand central cancer registries: Experience from Colorado.

Objective: To evaluate the quality of a multiyear linkage between the Colorado all-payer claims database (APCD) and the Colorado Central Cancer Registry.

Data Sources: Secondary 2012-2017 data from the APCD and the Colorado Cancer Registry.

Study Design: Descriptive analysis of the proportion of cases captured by the linkage in relation to the cases reported by the registry.

The Impact of Total Joint Arthroplasty on Long-Term Physical Activity: A Secondary Analysis of the Health and Retirement Study.

Objective: Physical inactivity is the fourth-leading cause of global mortality and is prevalent among people with lower extremity osteoarthritis. Lower extremity osteoarthritis is the most common arthritis type afflicting older adults, and total joint arthroplasty (TJA) performed to address the condition is Medicare's largest annual expense. Despite TJA intervention to address the disabling effects of osteoarthritis, physical activity (PA) level remains stable 6 months after TJA; however, the effect of TJA on long-term PA $(\ge$2 y) in a representative sample of older adults is unknown.

High Prevalence of Transjugular Intrahepatic Portosystemic Shunt Creation Without Prior Endoscopy During Acute Variceal Bleeding Hospitalization in the United States.

Current clinical guidelines by both American Association for the Study of Liver Disease and European Association for the Study of the Liver recommend endoscopy in all patients admitted with acute variceal bleeding within 12 hours of admission. Transjugular intrahepatic portosystemic shunt (TIPS) creation may be considered in patients at high risk if hemorrhage cannot be controlled endoscopically. We conducted a cross-sectional observational study to assess how frequently TIPS is created for acute variceal bleeding in the United States without preceding endoscopy.

Nonprofit Hospital Community Benefits: Collaboration With Local Health Departments to Address the Drug Epidemic.

Background: Nonprofit hospitals (NFPs) are required to provide community benefits, which have been historically focused on provision of medical care, to keep their tax exemption status. To increase hospital investment in community health, the Patient Protection and Affordable Care Act required NFPs to conduct community health needs assessments and address identified needs. Some states have leveraged this provision to encourage collaboration between NFPs and local health departments (LHDs) in local health planning.

Can Collaboration Between Nonprofit Hospitals and Local Health Departments Influence Population Health Investments by Nonprofit Hospitals?

Background: The patient protection and Affordable Care Act (ACA) sought to improve population health by requiring nonprofit hospitals (NFPs) to conduct triennial community health needs assessments and address the identified needs. In this context, some states have encouraged collaboration between hospitals and local health department (LHD) to increase the focus of community benefit spending onto population health.

Objectives: The aim was to examine whether a 2012 state law that required NFPs to collaborate with LHDs in local health planning influenced hospital population health improvement spending.

Association Between Increased Hospital Reimbursement for Cardiac Rehabilitation and Utilization of Cardiac Rehabilitation by Medicare Beneficiaries: An Interrupted Time Series.

Background: Although cardiac rehabilitation (CR) is a Class I Guideline recommendation, and has been shown to be a cost-effective intervention after a cardiac event, it has been reimbursed at levels insufficient to cover hospital operating costs. In January 2011, Medicare increased payment for CR in hospital outpatient settings by ≈180%. We evaluated the association between this payment increase and participation in CR of eligible Medicare beneficiaries to better understand the relationship between reimbursement policy and CR utilization.

Cost Analysis of Dialysis Access Maintenance Interventions across Physician Specialties in U.S. Medicare Beneficiaries.

Background Dialysis maintenance interventions account for billions of dollars in U.S. Medicare spending and are performed by multiple medical specialties.

Patient Sharing and Health Care Utilization Among Young Adults With Congenital Heart Disease.

Transitions from pediatric to adult care by young adults with chronic conditions are fraught with challenges. Poor transitions lead to discontinuities of care that are avoidable with better communication between providers. We tested whether exposure to providers with sustained patient-sharing relationships resulted in fewer emergent admissions of young adults with congenital heart disease (CHD).

Relationship between early follow-up and readmission within 30 and 90 days after ischemic stroke.

Objective: To examine whether early follow-up with primary care or neurology is associated with lower all-cause readmissions within 30 and 90 days after acute ischemic stroke admission.

Methods: We performed a retrospective cohort study of patients who were discharged home after acute ischemic stroke, identified by ICD-9 and ICD-10 codes, using PharMetrics, a nationally representative claims database of insured Americans from 2009 to 2015. The primary predictor was outpatient primary care or neurology follow-up within 30 and 90 days of discharge, and the primary outcome was all-cause 30- and 90-day readmissions.

The Impact of Home Health Physical Therapy on Medicare Beneficiaries With a Primary Diagnosis of Dementia.

Background: Dementia is a leading cause of disability for adults older than 65 years. Exercise intervention slows functional decline and improves balance; however, the efficacy of physical therapy (PT) services for persons with dementia is unknown. The purpose of this study is to assess the effect of home health PT services on physical function for Medicare beneficiaries with a primary diagnosis of dementia.

Risk of ESKD in Older Live Kidney Donors with Hypertension.

Background And Objectives: Hypertension in older kidney donor candidates is viewed as safe. However, hypertension guidelines have evolved and long-term outcomes have not been explored. We sought to quantify the 15-year risk of ESKD and mortality in older donors (≥50 years old) with versus those without hypertension.

State Laws and Nonprofit Hospital Community Benefit Spending.

Objective: To determine the association of state laws on nonprofit hospital community benefit spending.

Design: We used multivariate models to estimate the association between different types of state-level community benefit laws and nonprofit hospital community benefit spending from tax filings.

Setting: All 50 US states.

Urban-Rural Differences in Service Utilization and Costs of Care for Racial-Ethnic Groups Hospitalized With Poststroke Aphasia.

Objective: Although residence is a key contributor to cost and utilization in stroke patient care, its contribution to the care of persons with aphasia (PWA) is unknown. The objective of this study was to use discharge-level hospital inpatient data to examine the influence of patient residence (rural vs urban) and race-ethnicity on service utilization and cost of care among PWA.

Design: Cross-sectional.

Understanding The Relationship Between Medicaid Expansions And Hospital Closures.

Decisions by states about whether to expand Medicaid under the Affordable Care Act (ACA) have implications for hospitals' financial health. We hypothesized that Medicaid expansion of eligibility for childless adults prevents hospital closures because increased Medicaid coverage for previously uninsured people reduces uncompensated care expenditures and strengthens hospitals' financial position. We tested this hypothesis using data for the period 2008-16 on hospital closures and financial performance.

Coordination Program Reduced Acute Care Use And Increased Primary Care Visits Among Frequent Emergency Care Users.

Many high utilizers of the emergency department (ED) have public insurance, especially through Medicaid. We evaluated how participation in Bridges to Care (B2C)-an ED-initiated, multidisciplinary, community-based program-affected subsequent ED use, hospital admissions, and primary care use among publicly insured or Medicaid-eligible high ED utilizers. During the six months after the B2C intervention was completed, participants had significantly fewer ED visits (a reduction of 27.
