Conclusions • Intensive insulin therapy significantly reduced morbidity but not mortality among all patients in the medical ICU • Although the risk of subsequent death and disease was reduced in patients treated for three or more days, these patients could not be identified before therapy • Further studies are needed to confirm these preliminary data

MMC Initiatives – Glucose Control • 2006 - 2007 • “Yale Protocol” • 2008 • MMC-wide protocols • Infusions: • Tight (CTICU): 80 - 110 • Standard (CCM): 90 - 129 • Conservative (CVA/Head trauma): 120 – 179 • ICU > Transition > Floor > Discharge • 2009 • ? MHVN/State-wide standardization??

Hypoglycemia • Independent risk factor for ICU mortality? • Van der Berghe NEJM 2006 • Krinsley CCM 2007 • Brief episodes may be well-tolerated & safe, at least in the short-term • Vriesendorp CCM 2006 • Inconsistent definition(s) • Unclear significance of mild vs. profound hypoglycemia
HYPOGLYCEMIA (glucose <50)(Q3 2007 – Q2 2008) • 7656 ICU patient days (with at least one glucose value) • 50310 glucose values (6.57 values/patient day) • Rate per glucose value = 0.0029 (0.29%) • Rate per patient day = 0.0191 (1.9%)
