Bloodless Intensive Care: A Case Series and Review of Jehovah's Witnesses in ICU

The objective of this study was to assess the outcome of Jehovah's Witness (JW) patients admitted to a major Australasian ICU and to review the literature regarding the management of critically ill Jehovah's Witness patients.

All Jehovah's Witness patients admitted to the ICU between January 1999 and September 2003 were identified from a prospective database. Their ICU mortality, APACHE II scores, APACHE II risk of death and ICU length of stay were compared to the general ICU population. Twenty-one (0.24%) out of 8869 patients (excluding re-admissions) admitted to the ICU over this period were Jehovah's Witness patients. Their mean APACHE II score was 14.1 (±7.0), the mean APACHE II risk of death was 21.2% (±16.6), and the mean nadir haemoglobin (Hb) was 80.2 g/l (±36.4). Four out of 21 Jehovah's Witness patients died in ICU compared to 782 out of 8848 non- Jehovah's Witness patients (19.0% vs 8.8%, P=0.10, chi square). The median ICU length of stay in both groups was two days (P=0.64, Wilcoxon rank sum). The lowest Hb recorded in a survivor was 23 g/l.

Jehovah's Witness patients appear to be an uncommon patient population in a major Australasian ICU but are not over-represented when compared with their prevalence in the community. Despite similar severity of illness scores and predicted mortality to those in the general ICU population, there was a trend towards higher mortality in Jehovah's Witness patients.

Blood far forward: Time to get moving!

In planning for future contingencies, current problems often crowd out historical perspective and planners often turn to technological solutions to bridge gaps between desired outcomes and the reality of recent experience. The US Military, North Atlantic Treaty Organization, and other allies are collectively taking stock of 10-plus years of medical discovery and rediscovery of combat casualty care after the wars in Iraq and Afghanistan. There has been undeniable progress in the treatment of combat wounded during the course of the conflicts in Southwest Asia, but continued efforts are required to improve hemorrhage control and provide effective prehospital resuscitation that treats both coagulopathy and shock. This article presents an appraisal of the recent evolution in medical practice in historical context and suggests how further gains in far forward resuscitation might be achieved using existing technology and methods based on whole-blood transfusion while research on new approaches continues.

Blood Conservation Strategies in Cardiovascular Surgery

Blood conservation is a measurable intervention in which clinical and financial outcomes may be tracked. This article describes a systems approach to blood conservation for a cardiac surgery population. Four key areas are discussed: needs assessment, committee construction, blood conservation strategies, and outcome measurement. Specific evidenced-based blood conservation strategies include, but are not limited to, transfusion risk index, phlebotomy techniques, management of hemostasis and hemoglobin levels which includes blood testing, pharmacologic agents, and blood transfusion prescription guidelines.
