Randomised comparative effectiveness trial of Pulmonary Embolism Prevention after hiP and kneE Replacement (PEPPER): the PEPPER trial protocol.

Introduction: More than 1 million elective total hip and knee replacements are performed annually in the USA with 2% risk of clinical pulmonary embolism (PE), 0.1%-0.5% fatal PE, and over 1000 deaths.

Governance of Academic Health Centers and Systems: A Conceptual Framework for Analysis.

Health care has evolved from a cottage industry to a very complex one constituting nearly one-fifth of the U.S. economy.

The Mark Coventry Award: Prevention of readmission for venous thromboembolism after total knee arthroplasty.

Venous thromboembolism is the most common reason for readmission after total knee arthroplasty. Prospective contrast venography was conducted from 1984 to 2003 in 1321 patients undergoing total knee arthroplasty. Patients with deep venous thrombosis or pulmonary embolism were treated with warfarin; those with negative venograms received no further anticoagulation.

Resident selection: a key to the future of orthopaedics.

Recognizing the challenges presented in the process of resident selection, in 1981 the American Orthopaedic Association formed a Steering Committee on Resident Selection. This Committee was charged with studying the processes involved in the selection of orthopaedic residents and developing guidelines and making suggestions to program directors. The activities of the Committee focused on five areas: (1) the mechanics of resident selection; (2) the assessment of cognitive skills; (3) the assessment of motor ability; (4) the assessment of noncognitive factors (the affective domain); (5) the assessment of "dropouts.

The John Charnley Award: prevention of readmission for venous thromboembolic disease after total hip arthroplasty.

Unlabelled: Venous thromboembolic disease remains the most common reason for readmission after total hip arthroplasty. Prospective analysis of screening contrast venography was done from 1984 to 2003 in 1972 patients having elective total hip arthroplasty. Patients with deep venous thrombosis or pulmonary embolism received warfarin therapy; those with negative venograms received no further anticoagulation.
