Persistent effect of red cell transfusion on health-related quality of life after cardiac surgery.

Background: Although red blood cell transfusion has been associated with an increase in early morbid outcomes and reduced long-term survival after cardiac surgery, its relationship to functional quality of life after surgery has not been previously explored. Our objective was to investigate the relationship between perioperative red blood cell and component transfusion and functional health-related quality of life 6 to 12 months after cardiac surgery.

Methods: Of 12,536 patients undergoing cardiac surgical procedures between May 1995 and January 1999, 7,321 completed a self-administered Duke Activity Status Index (DASI) survey preoperatively and least one follow-up survey at nominally 6 or 12 months postoperatively.

Impact of prosthesis-patient size on functional recovery after aortic valve replacement.

Background: Prosthesis-patient size mismatch results when an implanted prosthetic aortic valve is of insufficient size for a patient's body surface area. The relation between prosthesis-patient size and functional capacity and adverse postoperative outcome is inconsistent. Our objectives were to examine the impact of valve replacement, continuous prosthesis-patient size, and other factors on functional recovery after aortic valve replacement (AVR) with the Duke Activity Status Index (DASI).

Changing of an anesthesiology clinical base year to create an integrated 48-month curriculum: experience of one program.

To allow for growth in our anesthesiology residency, we assumed control of the clinical base year (postgraduate year 1[PGY-1]) and adjusted the curriculum to accommodate the expanded size. With this opportunity to change the curriculum, we created a clinical base year to prepare PGY-1 for clinical anesthesia training in PGY-2 to PGY-4 using, for this purpose, the best resources of our clinical site. We describe the process and preliminary results of the change.

Health-related quality of life after coronary artery bypass grafting: a gender analysis using the Duke Activity Status Index.

Objective: Our objectives were to document the preoperative and postoperative functional status of patients undergoing coronary artery bypass grafting, to examine factors that influence functional recovery, and to determine whether gender differences exist in the preoperative and postoperative functional status with the Duke Activity Status Index.

Methods: One thousand eight hundred twenty-five patients undergoing isolated coronary artery bypass grafting had baseline and follow-up quality-of-life surveys. Mean follow-up from baseline to postoperative Duke Activity Status Index was 8.
