Medicaid coverage accuracy in electronic health records.
The objective of the study was to evaluate the validity of electronic health record (EHR) data for monitoring longitudinal Medicaid coverage and assess variation by patient demographics, visit types, and clinic characteristics. The researchers conducted a retrospective, observational study comparing Medicaid status agreement between Oregon community health center EHR data linked at the patient-level to Medicaid enrollment data (gold standard).

Medicaid expansion and health plan quality in Medicaid managed care.
The purpose of the study was to assess the effect of the 2014 Medicaid expansion on Medicaid managed care plan quality. The study concluded that Medicaid expansion increased enrollment in managed care plans, but it did not result in erosion of quality.

Landscape of living multiorgan donation in the United States: a registry-based cohort study.
This registry-based cohort study examined the patient characteristics and outcomes associated with living multiorgan donation in the United States. The authors assert that careful documentation of outcomes is needed to ensure ethical practices in selection, informed consent, and postdonation care of this unique donor community.

Effect of match-run frequencies on the number of transplants and waiting times in kidney exchange.
Many U.S. kidney paired donation (KPD) registries have gradually shifted to high-frequency match-runs, raising the question of whether this harms the number of transplants. The authors conducted simulations and found that longer intervals between match-runs do not increase the total number of transplants, and that prioritizing highly sensitized patients is more effective than waiting longer between match-runs for transplanting these patients. Further, increasing arrival rates of new pairs improves both the fraction of transplanted pairs and waiting times.

Oregon Medicaid Expenditures after the 2014 Affordable Care Act Medicaid expansion: over-time differences among new, returning, and continuously insured enrollees.
This study assessed health care expenditures among Medicaid enrollees in the 24 months after Oregon's 2014 Medicaid expansions and examine whether expenditure patterns were different among the newly, returning, and continuously insured (CI). After initial increases, newly and returning insured (RI) outpatient expenditures dropped below CI. Expenditures for emergency department and dental services among the RI remained higher than among the newly insured.

Offer acceptance practices and geographic variability in allocation model for end-stage liver disease at transplant.
Offer acceptance practices may cause geographic variability in allocation Model for End-Stage Liver Disease (aMELD) score at transplant and could magnify the effect of donor supply and demand on aMELD variability. To evaluate these issues, offer acceptance practices of liver transplant programs and donation service areas (DSAs) were estimated using offers of livers from donors recovered between January 1, 2016, and December 31, 2016.

Can accountable care organisations really improve the English NHS? Lessons from the United States.
The authors summarize evidence on accountable care organizations in the US - including what they look like, their effect on the quality and cost of healthcare, and how they are redesigning care. Recognizing major differences in context, they offer lessons from the US experience for National Health Service policy makers as they consider the future of similar ventures in England.

LivSim: An open-source simulation software platform for community research and development for liver allocation policies.
This brief discusses LivSim, an open-source software alternative to the Liver Simulated Allocation Model (LSAM) created by the Scientific Registry of Transplant Recipients. LivSim is an open-source simulation software platform for community research and development for liver allocation policies.
