Does the coronavirus disease 2019 (COVID-19) vaccination rate among healthcare personnel reflect their community? An evaluation of a multistate healthcare system.

Coronavirus disease 2019 (COVID-19) vaccination rates of a large health system reflected their respective service areas but varied by work role. Nurse vaccination rates were higher (56.9%) and rates among nursing support personnel were lower (38.

Use of intravenous magnesium sulfate among patients with acute myocardial infarction in China from 2001 to 2015: China PEACE-Retrospective AMI Study.

Objective: In 2001, Chinese guidelines for the care of acute myocardial infarction (AMI) included a new recommendation against the routine use of magnesium. We studied temporal trends and institutional variation in the use of intravenous magnesium sulfate in nationally representative samples of individuals hospitalised with AMI in China between 2001 and 2015.

Methods: In an observational study (China PEACE-Retrospective Study) of AMI care, we used a two-stage, random sampling strategy to create a nationally representative sample of 28 208 patients with AMI at 162 Chinese hospitals in 2001, 2006, 2011 and 2015.

The China Patient-centred Evaluative Assessment of Cardiac Events (PEACE) prospective heart failure study design.

Introduction: China faces the prospect of a large growth in the prevalence of heart failure (HF). However, there is limited knowledge about outcomes in patients after HF hospitalisations, including patient-reported outcomes (PROs). This paper is to present the study goal, methodology and data collection of the China Patient-centred Evaluative Assessment of Cardiac Events Prospective Heart Failure Study (China PEACE 5p-HF Study).

Sex differences in health outcomes at one year following acute myocardial infarction: A report from the China Patient-Centered Evaluative Assessment of Cardiac Events prospective acute myocardial infarction study.

Background: We examined sex differences in long-term health outcomes following acute myocardial infarction in China, including mortality, major adverse cardiac events and health status (symptoms, functioning, quality of life).

Methods: A total of 3415 acute myocardial infarction patients (23.2% women) aged ⩾18 years were enrolled across 10 geographic regions in China (2012-2014) in the China Patient-Centered Evaluative Assessment of Cardiac Events (PEACE) study.

Implications of the 2013 ACC/AHA cholesterol guidelines for adults in contemporary cardiovascular practice: insights from the NCDR PINNACLE registry.

Background: In a significant update, the 2013 American College of Cardiology/American Heart Association (ACC/AHA) cholesterol guidelines recommend fixed-dose statin therapy for those at risk and do not recommend nonstatin therapies or treatment to target low-density lipoprotein cholesterol (LDL-C) levels, limiting the need for repeated LDL-C testing.

Objectives: The goal of this study was to examine the impact of the 2013 ACC/AHA cholesterol guidelines on current U.S.

Clopidogrel use and hospital quality in medically managed patients with non-ST-segment-elevation myocardial infarction.

Background: Clopidogrel prescription is a class I guideline recommendation for medically managed patients with non-ST-segment-elevation myocardial infarction (NSTEMI). However, clopidogrel has historically been underused in this population. We evaluated contemporary rates of its use and evaluated associated factors, with a particular focus on hospital quality of myocardial infarction (MI) care.

Regional variation in cardiac catheterization appropriateness and baseline risk after acute myocardial infarction.

Objectives: We evaluated whether appropriateness and baseline risk of cardiac catheterization varied according to regional intensity of invasive therapy after acute myocardial infarction (AMI), and whether AMI mortality varied according to invasive intensity regions.

Background: Marked regional variations exist in cardiac invasive procedure use after AMI within the U.S.

Regional differences in process of care and outcomes for older acute myocardial infarction patients in the United States and Ontario, Canada.

Background: Previous comparisons of acute myocardial infarction (AMI) treatment between the United States and Canada are limited because they compared selected patients from randomized trials, used administrative data that lacked clinical detail, or did not consider regional differences in AMI treatment.

Methods And Results: We compared medication use, invasive cardiac procedure use, and 30-day risk-standardized mortality rates of 38,886 fee-for-service Medicare beneficiaries hospitalized with AMI in the United States and 5634 similarly aged patients in Ontario, Canada, from 1998 and 2001. Baseline characteristics and illness severity across the US regions and Ontario were not substantially different.

The impact of diabetes on one-year health status outcomes following acute coronary syndromes.

Background: Diabetes is an important predictor of mortality patients with ACS. However, little is known about the association between diabetes and health status after ACS. The objective of this study was to examine the association between diabetes and patients' health status outcomes one year after an acute coronary syndrome (ACS).
