The proportion of bacteraemias caused by biliary tract infection was 5.5%. The most common infecting organisms were E coli and K pneumoniae. There was a strong association with choledocholithiasis and malignancies, both pre-existing and newly diagnosed. Death was uncommon but when it occurred was often caused by septic shock within 48 h of presentation.

Constipation, emesis, and confusion were associated with increased p-LOS in patients receiving opioids after orthopedic surgery. In addition, there was a significant linear relationship between the number of adverse effects/patient and increased p-LOS, and the strength of the association increased as the number of adverse effects increased. Although the opioid dosages and adverse-effect rates were typical, these findings reinforce the need to balance pain management with risk of events.

the cost of blood continues to increase and price varies by geography. However, the rate of increase in acquisition costs for red blood cells appears to be slowing. This information should be used by organizations and policy makers to improve financing and utilization management for blood components and services.
