Background: Though a growing number of U.S. Veterans are being diagnosed with cannabis use disorders, with posttraumatic stress disorder (PTSD) observed as the most frequently co-occurring psychiatric disorder among this population, no research has investigated the impact of PTSD diagnosis on cannabis quit success.
Objectives: The present study so...
Aims:
Aortic valve surgery in the presence of reduced ejection fraction (EF) or low transaortic gradient is associated with adverse outcome. Low gradient (LG) may be associated with reduced EF, known as low EF-low gradient (LEF-LG), or "paradoxically" low with normal EF (P-LG). Our aim was to investigate the impact of EF and transaortic gradient o...
Hospital acute myocardial infarction (AMI) care is increasingly evaluated using composite quality scores. We investigated the influence of three aggregation methods for an AMI indicator on mortality and hospital rank.
We studied 136,392 patients discharged alive from 199 hospitals with AMI recorded in the Myocardial Ischaemia National Audit Project...
To prospectively investigate the relation between cannabis use expectancies and cannabis use prior to and during a self-initiated cannabis cessation attempt.
Cohort design that followed participants for 4 weeks following a self-initiated cessation attempt.
United States Department of Veterans Affairs medical center.

Background Mortality rates after hospitalisation for acute myocardial infarction (AMI) have fallen substantially, but vary by hospital. Whilst previous studies have reported the extent to which the residual (unexplained) variance in outcomes from AMI can be attributed to patients and hospitals, there are no reports quantifying hospital level residu...
Introduction The management of patients with ST-elevation myocardial infarction (STEMI) involves a number of evidence-based therapies. However, all recommended opportunities for care may not be achieved during the hospital stay. We quantified the missed opportunities for hospitals to provide care and investigated the impact of this on 30-day and 6-...
Purpose: Hospital cardiovascular care is increasingly evaluated using composite quality scores. We investigated the influence of three aggregation methods for an acute myocardial infarction (AMI) indicator on early and late mortality, and hospital rank.
Methods: We studied 136,392 patients discharged alive from hospital with AMI between 1st January...
