Vitamin D is very important in the Intensive Care Unit of the hospital
Many ICU studies in 2011 have shown that

• Many people in ICU are low on vitamin D
• Those in ICU who are low on vitamin D: stay longer, are more likely to die, and get more infections

Here are some ICU references at VitaminDWiki

• ICU patients with low vitamin D stayed longer and had more sepsis – Dec 2011 The most recent paper
• ICU time is 2X more likely to be longer than 2 days if vitamin D less than 20 ng – Mar 2011
• Critical Care patients with low vitamin D were 85 percent more likely to die – Sept 2011
• Virtually all veterans in ICU had vitamin D less than 32 ng – Jan 2011
• veterans with enough vitamin D were almost 2X more likely to survive ICU – Oct 2010
• Study: 540,000 IU oral to ten patients near death in an ICU as a single dose achieved around 40 ng/ml, but it takes three days to do so
  • "I predict that eventually vitamin D will be available as an IV and that the most useful preparation will be intravenous 25(OH)D."
• Vitamin D might reduce sepsis
• MRSA inpatient cost 2X higher if less than 20 ng vitamin D – June 2011
• Staph infection reduced 50 percent when have more than 30 ng of vitamin D – Aug 2011
