Several Centers for Medicare and Medicaid Services (CMS) programs aim to transform how health care is delivered by adjusting Medicare inpatient hospital payments through a system of rewards and penalties based on performance on measures of quality. These programs are the Hospital Readmissions Reduction Program, the Hospital Value-Based Purchasing Program, and the Hospital-Acquired Condition Reduction Program. We analyzed value-based program penalty results for various groups of hospitals across these three programs and assessed the impact of patient and community health equity risk factors on hospital penalties.

Background: While non-invasive ventilation at home (NIVH) is gaining wider acceptance as a treatment option for chronic obstructive pulmonary disease with chronic respiratory failure (COPD-CRF), uncertainty remains about the optimal time to begin NIVH, whether a specific phenotype of COPD-CRF predicts improved outcomes, and how NIVH affects healthcare costs.

Materials And Methods: Using 100% research identifiable fee-for-service Medicare claims from 2016 through 2020, we designed an observational, retrospective, cohort study to determine how NIVH use in COPD-CRF patients stratified by CRF phenotype and by timing of initiation affected mortality, healthcare utilization, and total healthcare costs compared to a matched control group.

Results: In hypercapnic COPD-CRF patients starting NIVH within the first week following diagnosis, risk of death was reduced by 43% (HR, 0.

To compare outcomes for Medicare patients with diabetic foot ulcer(s) (DFU) receiving cryopreserved placental membrane containing viable cells (vCPM) to other Cellular- and Tissue-Based Products (CTPs). Patients with DFU and CTP use were selected in Medicare claims (2013-2017) by using a strict definition of DFU with demonstrated diabetes etiology. We compared the effectiveness of vCPM with other CTPs on: (1) reduction of post-treatment ulcer occurrence, and (2) reduction in 1 year mortality.

Aims: There is wide variation in opioid prescribing patterns after common surgical procedures. This study examines outcomes for beneficiaries undergoing hospital outpatient department (HOPD) procedures using liposomal bupivacaine (LB) for control of post-surgical pain. As a non-opioid surgical analgesic, LB may afford beneficial outcomes for reducing subsequent opioid use and improving post-surgical service use outcomes.

Background: There are few studies of the economic value of orthotic and prosthetic services. A prior cohort study of orthotic and prosthetic Medicare beneficiaries based on Medicare Parts A and B claims from 2007 to 2010 concluded that patients who received timely orthotic or prosthetic care had comparable or lower total health care costs than a comparison group of untreated patients. This follow-up study reports on a parallel analysis based on Medicare claims from 2011 to 2014 and includes Part D in addition to Parts A and B services and expenditures.

Issue: Safety-net hospitals play a vital role in delivering health care to Medicaid enrollees, the uninsured, and other vulnerable patients. By reducing the number of uninsured Americans, the Affordable Care Act (ACA) was also expected to lower these hospitals’ significant uncompensated care costs and shore up their financial stability.

Goal: To examine how the ACA’s Medicaid expansion affected the financial status of safety-net hospitals in states that expanded Medicaid and in states that did not.

After accounting for supplemental payments, we found that in 2011, disproportionate-share hospitals, on average, received gross Medicaid payments that totaled 108 percent of their costs for treating Medicaid patients but only 89 percent of their costs for Medicaid and uninsured patients combined. However, these payments were reduced by approximately 4-11 percent after we accounted for provider taxes and local government contributions that are used to help finance Medicaid payments.

Context: There are few studies of the economic impact or value of lower extremity prosthetic services. Results from this study can inform the value proposition concerning prosthetic services within military health, where over 40,000 Veterans with limb-loss receive care for their amputations through the Veterans Administration health care system.

Purpose: To determine the extent to which Medicare patients who received selected prosthetic services had less health care utilization, lower Medicare payments, and/or fewer negative outcomes compared to matched patients not receiving these services.

Background: Patients are being exposed to increasing levels of ionizing radiation, much of it from computed tomography (CT) scans.

Methods: Adults without a cancer diagnosis who received 10 or more CT scans in 2010 were identified from North Carolina Medicaid claims data and were sent a letter in July 2011 informing them of their radiation exposure; those who had undergone 20 or more CT scans in 2010 were also telephoned. The CT scan exposure of these high-exposure patients during the 12 months following these interventions was compared with that of adult Medicaid patients without cancer who had at least 1 CT scan but were not in the intervention population.

Medicare skilled nursing facility (SNF) residents with chronic wounds require more resources and have relatively high healthcare expenditures compared to Medicare patients without wounds. A retrospective cohort study was conducted using 2006 Medicare Chronic Condition Warehouse claims data for SNF, inpatient, outpatient hospital, and physician supplier settings along with 2006 Long-Term Care Minimum Data Set (MDS) information to compare Medicare expenditures between two groups of SNF residents with a diagnosis of pressure, venous, ischemic, or diabetic ulcers whose wounds healed during the 10-month study period. The study group (n = 372) was managed using a structured, comprehensive wound management protocol provided by an external wound management team.

Introduction: Little is known regarding how to accomplish large-scale health care improvement. Our goal is to improve the quality of chronic disease care in all primary care practices throughout North Carolina.

Methods: Methods for improvement include (1) common quality measures and shared data system; (2) rapid cycle improvement principles; (3) quality-improvement consultants (QICs), or practice facilitators; (4) learning networks; and (5) alignment of incentives.

Objective: To determine if the instant approval (IA) process differs from the traditional prior authorization (PA) process in preferred drug channeling, resultant gaps in therapy, and provider dissatisfaction.

Study Design: An interrupted time series analysis using pharmacy claims and a retrospective cohort study.

Methods: The study assessed changes in preferred drug use and subsequent cost reductions.

Two key health reform bills in the House of Representatives and Senate include the option of a "public plan" as an additional source of health coverage. At least initially, the plan would primarily be structured to cover many of the uninsured and those who now have individual coverage. Because it is possible, and perhaps even likely, that this new public payer would pay less than private payers for the same services, such a plan could negatively affect hospital margins.

Providers with lower costs may be more efficient and, therefore, provide better care than those with higher costs. However, the relationship between risk-adjusted costs (often described as efficiency) and quality is not well understood. We examined the relationship between hospitals' risk-adjusted costs and their structural characteristics, nursing levels, quality of care, and outcomes.

The United States leads the world in health care costs but ranks far below many developed countries in health outcomes. Finding ways to narrow this gap remains elusive. This article describes the response of one state to establish community health networks to achieve quality, utilization, and cost objectives for the care of its Medicaid recipients.
