The goal of Universal Health Coverage (UHC) is that everyone needing healthcare can access quality services without financial hardship. Recent research covering countries with UHC systems documents the emergence, and acceleration following the COVID-19 pandemic of unapproved informal payment systems by providers that collect under-the-table payments from patients. In 2001, Thailand extended its '30 Baht' government-financed coverage to all uninsured people with little or no cost sharing.

Rising prices are a major cause of increased health care spending and health insurance premiums in the US. Hospital prices, specifically-for both inpatient and outpatient care-are the largest driver of rising health care spending in the commercial insurance market. As a result, policy makers and employers are increasingly interested in understanding the determinants of hospital prices.

Introduction: Hospital-based emergency departments have been a sustained source of overall hospital utilization in the United States. In 2019, an estimated 150 million hospital-based emergency department (ED) visits occurred in the United States, up from 90 million in 1993, 108 million in 2000 and 137 million in 2015. This study analyzes hospital ED visit registration data pre and post to the COVID-19 pandemic describe the impact of on hospital ED utilization and to assess long-term implications of COVID and other factors on the utilization of hospital-based emergency services.

The authors evaluated the presence of paclitaxel and healing of distal hind limb wounds created in 27 swine using biopsy punches followed by paclitaxel-coated balloon (PCB) use in the iliofemoral arteries of healthy swine. After 14 and 28 days, no differences were seen in time course, appearance, and histopathology of wound healing between the single or triple PCB and uncoated balloon treatment despite clinically relevant paclitaxel concentrations in the skin adjacent to the healing wounds. Presence of paclitaxel downstream from the PCB treatment site does not impair the wound healing response of preexisting distal cutaneous lesions in healthy swine.

Objectives: Empirical evaluation of market power that hospitals gain over health plans through hospitals' ability to cancel their contracts with plans while keeping large shares of plans' emergency patients and getting paid for them at above-market rates.

Study Design: Case-study analysis of 5 California hospitals that initially had contracts with most commercial health plans and then cancelled all those contracts at the same time.

Methods: We conducted a before-and-after case-study analysis comparing volume, price, and net revenues for the 5 study hospitals 3 years before and up to 4 years after the cancellation of their commercial contracts.

Aims: Peripheral arteries are constantly exposed to deformation (elongation, twisting, shortening, compression) making bioresorbable scaffolds (BRS) a potentially attractive therapeutic alternative to metallic stents. We conducted a long-term pilot preclinical study of a novel sirolimus-eluting BRS in peripheral arteries.

Methods And Results: Fourteen BRS were deployed in iliofemoral arteries of seven healthy Yucatan miniswine and examined with imaging, pharmacokinetic, histopathologic, and polymer degradation techniques at 0, 30, 90, 180 days, 1, 2, and 3.

California became very successful in controlling rising health care costs by promoting price competition through market-based, managed care policies. However, recent data reveal that the state has not been able sustain its initial success in controlling growth in hospital prices. Two powerful trends emerged in California that eroded the conditions needed to sustain price competition.

Although research indicates that organizational characteristics substantially influence the adoption and use of evidence-based practices (EBPs), there has been little empirical research on organizational factors most likely to influence successful implementation of EBPs, particularly in criminal justice settings. This study examined organizational characteristics related to the success of change teams in achieving improvements in assessment and case-planning procedures for persons leaving correctional settings and receiving community services. In this evaluation of the Organizational Process Improvement Intervention (OPII), part of the National Institute on Drug Abuse's (NIDA's) Criminal Justice Drug Abuse Treatment Studies (CJDATS) cooperative, 21 sites were randomized to an early-start or a delayed-start condition.

A surge in hospital consolidation is fueling formation of ever larger multi-hospital systems throughout the United States. This article examines hospital prices in California over time with a focus on hospitals in the largest multi-hospital systems. Our data show that hospital prices in California grew substantially (+76% per hospital admission) across all hospitals and all services between 2004 and 2013 and that prices at hospitals that are members of the largest, multi-hospital systems grew substantially more (113%) than prices paid to all other California hospitals (70%).

In 2009 HealthCare Partners Affiliates Medical Group, based in Southern California, launched House Calls, an in-home program that provides, coordinates, and manages care primarily for recently discharged high-risk, frail, and psychosocially compromised patients. Its purpose is to reduce preventable emergency department visits and hospital readmissions. We present data over time from this well-established program to provide an example for other new programs that are being established across the United States to serve this population with complex needs.

Background: In 2001, Thailand implemented a universal coverage program by expanding government-funded health coverage to uninsured citizens and limited their out-of-pocket payments to 30 Baht per encounter and, in 2006, eliminated out-of-pocket payments entirely. Prior research covering the early years of the program showed that the program effectively expanded coverage while a more recent paper of the early effects of the program found that improved access from the program led to a reduction in infant mortality.

Objective: We expand and update previous analyses of the effects of the 30 Baht program on access and out-of-pocket payments.

Background: The Organizational Process Improvement Intervention (OPII), conducted by the NIDA-funded Criminal Justice Drug Abuse Treatment Studies consortium of nine research centers, examined an organizational intervention to improve the processes used in correctional settings to assess substance abusing offenders, develop case plans, transfer this information to community-based treatment agencies, and monitor the services provided by these community based treatment agencies.

Methods/design: A multi-site cluster randomized design was used to evaluate an inter-agency organizational process improvement intervention among dyads of correctional agencies and community based treatment agencies. Linked correctional and community based agencies were clustered among nine (9) research centers and randomly assigned to an early or delayed intervention condition.

Background: United States health care spending rose rapidly in the 2000s, after a period of temporary slowdown in the 1990s. However, the description of the overall trend and the understanding of the underlying drivers of this trend are very limited. This study investigates how well historical hospital cost/revenue drivers explain the recent hospital spending trend in the 2000s, and how important each of these drivers is.

Millions of uninsured Americans rely on hospital emergency departments (EDs) for medical care. Throughout the United States, uninsured patients treated in or admitted to the hospital through the ED receive hospital bills based on what hospitals call "billed charges." These charges are much higher than those paid by insured patients.

Icy bodies may have delivered the oceans to the early Earth, yet little is known about water in the ice-dominated regions of extrasolar planet-forming disks. The Heterodyne Instrument for the Far-Infrared on board the Herschel Space Observatory has detected emission lines from both spin isomers of cold water vapor from the disk around the young star TW Hydrae. This water vapor likely originates from ice-coated solids near the disk surface, hinting at a water ice reservoir equivalent to several thousand Earth oceans in mass.

The long-term trend of consolidation among US health plans has raised providers' concerns that the concentration of health plan markets can depress their prices. Although our study confirmed that, it also revealed a more complex picture. First, we found that 64 percent of hospitals operate in markets where health plans are not very concentrated, and only 7 percent are in markets that are dominated by a few health plans.

This study examined engagement in treatment in substance abuse treatment programs that treated primarily either African American or White clients. Findings showed higher levels of engagement in White programs; however, engagement of African Americans in White programs was similar to that of Whites and was greater than Whites in African American programs. No significant differences emerged when a mixed model analysis considered additional variables of staff consensus (regarding treatment elements), treatment climate, acceptance of Medicaid clients, the proportion mandated to treatment, and the quality of the physical space.
