Can hospital structural and financial characteristics explain variations in mortality caused by acute myocardial infarction?

Each year 1 in 160 people in the United States suffers from acute myocardial infarction (AMI). Of these more than 1.5 million cases annually, 500,000 end in fatalities. This study's purpose was to describe and evaluate the role hospital characteristics play in rates of mortality caused by AMI in acute-care California hospitals. Characteristics evaluated include structural characteristics--i.e., teaching status, percentage of board-certified physicians, registered nurse hours per patient day (RN hours/patient day), volume of cases, technological resource availability, and urban density; and financial characteristics--profit status and total operating expenses per patient day. Although part of a larger investigation correlating mortality and length of stay, this article reports only the results for significant influences on mortality.

Demystifying the influence of hospital characteristics on inpatient mortality rates.

Death, although not the only measure of adverse outcome, has been studied more than any other single occurrence. The authors discuss the findings of these studies and propose a conceptual framework to explain the relation between several hospital characteristics (e.g., profit status, RN ratios) and inpatient mortality rates. These studies raise the issue of whether some hospital characteristics are distal contributors and others, such as RN ratios, are more proximal explanatory variables of the mortality rate. Implications for understanding the relation of nursing's role in the array of potential contributors are discussed.

Magnetic resonance imaging of the adrenal glands: a comparison with computed tomography.

This investigation compared magnetic resonance imaging (MRI) with computed tomography (CT) in the evaluation of normal and abnormal adrenal glands. Thirty normal volunteers were studied with MRI, and the results were compared with a retrospective review of 30 normal CT examinations. CT identified both adrenal glands in all 30 patients. MRI identified both glands in 29 of 30 volunteers. There were no statistically significant differences between the two imaging techniques using chi-square analysis. Twenty-one patients with abnormal adrenal gland(s) detected with CT were also studied with MRI. The abnormalities studied included bilateral hyperplasia (three patients), adenoma (two), myelolipoma (one), adrenal metastases (six), adrenal hemorrhage (two), and neuroblastoma (seven). MRI detected the abnormal adrenal gland(s) in 20 of 21 patients. MRI was unable to detect calcifications in the lesions studied but more clearly showed the relations of adrenal masses to the major vascular structures. MRI demonstrated corticomedullary differentiation in patients with adrenal hyperplasia and in some normal volunteers. The CT and MRI features of the adrenal lesions are discussed.
