Maternal MortalityMaternal Mortality -- Safe Motherhood InitiativeSafe Motherhood Initiative -- In 2002 the “Safe Motherhood Initiative” was launched as a joint venture between NYS Dept of Health and ACOG District II.of Health and ACOG District II. The goals of the program : 1. - Overall decrease in maternal mortality: 2. - Eliminates the disparity between white and black women
  3. 3. Maternal MortalityMaternal Mortality -- Safe Motherhood InitiativeSafe Motherhood Initiative -- Reporting Maternal Deaths through the S.M.I. was on a voluntary basis from 8/03 through 6/05 there were 37 Maternal Deaths reported6/05 there were 37 Maternal Deaths reported to ACOG District II through the S.M.I.

  56. 56. Septic Shock - Management - A. The primary outcome variable was survival to hospital discharge. Methods Kumar et al Crit Care Med, 2006 hospital discharge. B. The primary independent variable was the time to initiation of effective antimicrobial therapy relative to the first occurrence of shock (persistent hypotension)
  57. 57. Septic Shock - Management - A. Mortality for the entire population 56% B. Survival was similar: Outcome Kumar et al Crit Care Med, 2006 B. Survival was similar: - Infection documented or suspecetd - A plausible pathogen identified or not - Bacteremia present or absent
