Interdonor Incompatibility Due to Anti-Kell Antibody Undetectable by Automated Antibody Screening

A unit of whole donor blood, the plasma of which contained anti-Kell antibody, was transfused into a Kell-negative patient who had received a unit of Kell-positive blood 4 weeks previously. A haemolytic transfusion reaction ensued. The antibody had gone undetected in routine automated screening of the donor blood. Automated antibody detection techniques do not offer reliable detection of anti-Kell antibodies.     

Exit-site location does not influence peritoneal catheter infection rate

Peritoneal catheter infections are a cause of peritonitis, catheter loss, and permanent transfer of continuous ambulatory peritoneal dialysis (CAPD) patients to hemodialysis. Risk factors for catheter infections have not been delineated. We investigated the location of the peritoneal exit-site location as a risk factor for catheter infection and loss. There was no relationship between catheter infection rates and exit location. Catheters exiting on the beltline had a median infection rate of 0.5 episodes/year, as opposed to 1.2 episodes/year for catheters exiting above the beltline and 0.9 episodes/year for catheters exiting below the beltline (ns). The percentage of catheters that became infected and required removal was the same for catheters exiting above, below, or on the beltline. Although we recommend avoiding the beltline for patient comfort, exit-site location is not an important determinant of infection rates or catheter outcome.     

Patient empowerment in the United States: a critical commentary

Whilst there is no consensus amongst analysts regarding how best to define 'patient empowerment', at the very least, this concept entails a re-distribution of power between patients and physicians. Empowered patients attempt to take charge of their own health and their interactions with health care professionals. Empowerment can occur at different levels (micro, meso, and macro) and patients have different ideas about what it means to 'take charge' and 'be empowered'. Some patients simply want to be given information about their conditions whilst others want to have full control over all medical decision-making. Some empirical evidence suggests that active patient participation in health care is associated with better patient outcomes. This field is ripe for future studies which both help to develop theoretical models of patient empowerment and articulate the conditions under which patient empowerment occurs.
