Randomized Controlled Trial Multicenter Study Clinical Trial
E5 murine monoclonal antiendotoxin antibody in gram-negative sepsis: a randomized controlled trial. E5 Study Investigators.
Knowledge and understanding of gram-negative sepsis have grown over the past 20 years, but the ability to treat severe sepsis successfully has not. ⋯ Despite adequate sample size and high enrollment of patients with confirmed gram-negative sepsis, E5 did not improve short-term survival. Current study rationale and designs should be carefully reviewed before further large-scale studies of patients with sepsis are conducted.

Historical Article
American medical malpractice litigation in historical perspective.
Medical malpractice and the problems associated with it remain an important issue in the US medical community. Yet relatively little information regarding the long-term history of malpractice litigation can be found in the literature. This article addresses 2 questions: (1) when and why did medical malpractice litigation originate in the United States and (2) what historical factors best explain its subsequent perpetuation and growth? Medical malpractice litigation appeared in the United States around 1840 for reasons specific to that period. ⋯ Three of these factors are medical: the innovative pressures on American medicine, the spread of uniform standards, and the advent of medical malpractice liability insurance. Three are legal factors: contingent fees, citizen juries, and the nature of tort pleading in the United States. Knowledge of these historical factors may prove useful to those seeking to reform the current medical malpractice litigation system.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Comparison of vignettes, standardized patients, and chart abstraction: a prospective validation study of 3 methods for measuring quality.
Better health care quality is a universal goal, yet measuring quality has proven to be difficult and problematic. A central problem has been isolating physician practices from other effects of the health care system. ⋯ Our data indicate that quality of health care can be measured in an outpatient setting by using clinical vignettes. Vignettes appear to be a valid and comprehensive method that directly focuses on the process of care provided in actual clinical practice. Vignettes show promise as an inexpensive case-mix adjusted method for measuring the quality of care provided by a group of physicians.

Randomized Controlled Trial Multicenter Study Clinical Trial
Effect of metformin and rosiglitazone combination therapy in patients with type 2 diabetes mellitus: a randomized controlled trial.
Most antidiabetic agents target only 1 of several underlying causes of diabetes. The complementary actions of the antidiabetic agents metformin hydrochloride and rosiglitazone maleate may maintain optimal glycemic control in patients with type 2 diabetes; therefore, their combined use may be indicated for patients whose diabetes is poorly controlled by metformin alone. ⋯ Our data suggest that combination treatment with once-daily metformin-rosiglitazone improves glycemic control, insulin sensitivity, and beta-cell function more effectively than treatment with metformin alone.
