Characteristics, Outcomes, and Trends of Patients With COVID-19-Related Critical Illness at a Learning Health System in the United States.

Background: The coronavirus disease 2019 (COVID-19) pandemic continues to surge in the United States and globally.

Objective: To describe the epidemiology of COVID-19-related critical illness, including trends in outcomes and care delivery.

Design: Single-health system, multihospital retrospective cohort study.

Administration costs of intravenous chemotherapy in treating peripheral T-cell lymphoma.

Objective: This retrospective cohort analysis was conducted to examine the cost components of administering IV chemotherapy to peripheral T-cell lymphoma (PTCL) patients in the US to inform decision makers.

Methods: Patients diagnosed with PTCL (ICD-9 code 202.7X) between 1 October 2007 and 30 September 2012 were identified from a US administrative claims database.

The impact of hospital pay-for-performance on hospital and Medicare costs.

Objective: To evaluate the effects of Medicare's hospital pay-for-performance demonstration project on hospital revenues, costs, and margins and on Medicare costs.

Data Sources/study Setting: All health care utilization for Medicare beneficiaries hospitalized for acute myocardial infarction (AMI; ICD-9-CM code 410.x1) in fiscal years 2002-2005 from Medicare claims, containing 420,211 admissions with AMI.

Impact of public reporting on unreported quality of care.

Objective: The impact of quality improvement incentives on nontargeted care is unknown and some have expressed concern that such incentives may be harmful to nontargeted areas of care. Our objective is to examine the effect of publicly reporting quality information on unreported quality of care.

Data Sources/study Setting: The nursing home Minimum Data Set from 1999 to 2005 on all postacute care admissions.

Analysis of costs associated with administration of intravenous single-drug therapies in metastatic breast cancer in a U.S. population.

Background: An estimated $8.1 billion (in 2004 dollars) is spent annually on total health care costs for the treatment of breast cancer in the United States. Breast cancer has traditionally been treated with intravenous (IV) cancer therapies that entail not only the drug acquisition cost, but additional costs of personnel time, supplies, and equipment used in the preparation and administration of the IV drug.

Variation in cardiac procedure use and racial disparity among Veterans Affairs Hospitals.

Background: Lower or less racially equitable cardiac procedure rates at Veterans Affairs medical centers (VAMCs) with larger minority populations may be sources of racial disparities. This study's objectives were to determine if VAMCs with higher proportions of black inpatients performed fewer cardiac procedures or had larger racial differences in procedure rates than predominantly white VAMCs.

Methods: We identified 87536 potential candidates for bioprosthetic aortic valve replacement, 50517 for implanted cardioverter/defibrillator (ICD), 92292 for dual-chambered pacemaker (DCP), and 70269 for percutaneous coronary intervention (PCI) hospitalized between 1998 and 2003.
