ReviewA systematic review of outcomes and quality measures in adult patients cared for by hospitalists vs nonhospitalists.
A systematic review of English-language literature was undertaken to answer the question, "Are there differences in cost or quality of inpatient medical care provided to adults by hospitalists vs nonhospitalists?" A computerized search was performed, using hospitalist and either quality, outcome, or cost as search terms. References from relevant articles were searched by hand. ⋯ Three reports show improvement in outcomes for orthopedic surgery patients who had hospitalist consultation or comanagement, 3 reports show improvement in markers of quality of care for patients with pneumonia, and 2 reports show improvement in aspects of heart failure management. Further research should seek to determine why differences in care exist, whether these improvements might be generalized to other physicians, and whether hospitalists provide demonstrable benefit in other areas of care.

Patients' attitudes and preferences about participation and recruitment strategies in clinical trials.
To assess attitudes of patients about participation in clinical trials. ⋯ Patients are interested in participating in clinical trials but commonly lack adequate information. If patients received more information (through their treating physicians), enrollment might improve. This single-site study has limited generalizability. Future studies involving a diverse group of patients from a broader geographic distribution will help provide more definitive results.

A cross-sectional study of intima-media thickness, ethnicity, metabolic syndrome, and cardiovascular risk in 2268 study participants.
To describe the association between intima-media thickness (IMT) and metabolic syndrome (MetS) and to examine if the addition of IMT to a traditional MetS definition adds value to the assessment of predicted cardiovascular disease (CVD) risk in a large multiethnic population. ⋯ The addition of IMT to the traditional criteria for the diagnosis of the MetS may help identify individuals who otherwise would not have been identified to be at high risk of CVD.

Carotid intima-media thickness and coronary artery calcium score as indications of subclinical atherosclerosis.
To determine the ability of carotid intima-media thickness (CIMT) and coronary artery calcium score (CACS) to detect subclinical atherosclerosis in a young to middle-aged, low-risk, primary-prevention population. ⋯ Subclinical vascular disease can be detected by CIMT evaluation in young to middle-aged patients with a low FRS and a CACS of zero. These findings have important implications for vascular disease screening and the implementation of primary-prevention strategies.

Ventricular tachycardia (VT), which most commonly occurs in patients with structural heart disease, can be associated with an increased risk of sudden death. The most common cause of ventricular fibrillation is acute coronary ischemia, whereas a myocardial scar from prior infarct is the most common cause of sustained monomorphic VT in patients with structural heart disease. More benign forms of idiopathic VT can also occur in the absence of structural heart disease. ⋯ The left ventricular ejection fraction is most frequently used to stratify patients with either ischemic or nonischemic cardiomyopathy who are at risk of sudden death and may be candidates for a prophylactic defibrillator. Catheter ablation may also be an option for appropriately selected patients with many forms of VT. This article discusses the etiologies and management of VT and its association with sudden death.
