title: Evaluation of a strict protocol approach in managing women with severe disease due to hypertension in pregnancy: a before and after study.
abstract: BACKGROUND
  To evaluate whether the introduction of a strict protocol based on the systemic evaluation of critically ill pregnant women with complications of hypertension affected the outcome of those women.
  
  
  METHODS
  
  
  
  METHODS
  Indigent South African women managed in the tertiary hospitals of the Pretoria Academic Complex. Since 1997 a standard definition of women with severe acute maternal morbidity (SAMM), also referred to as a Nearmiss, has been used in the Pretoria Academic Complex. All cases of SAMM and maternal deaths (MD) were entered on the Maternal Morbidity and Mortality Audit System programme (MaMMAS). A comparison of outcome of severely ill women who had complications of hypertension in pregnancy was performed between 1997-1998 (original protocol) and 2002-2003 (strict protocol). Data include women referred from outside the Pretoria Academic Complex area to the tertiary hospitals.
  
  
  RESULTS
  Between 1997-1998 there were 79 women with SAMM and 18 maternal deaths due to complications of hypertension, compared with 91 women with SAMM and 13 maternal deaths in 2002-2003. The mortality index (MI) declined from 18.6% to 12.5% (OR 0.62, 95% CI 0.27-1.45). Statistically significant fewer women had renal failure (RR 0.37, 95% CI 0.21-0.66) and cerebral complications (RR 0.52, 95% CI 0.34-0.81) during the second period, and liver dysfunction (RR 0.27 95% CI 0.06-1.25) tended to be lower. However, there tended to be an increase in the number of women, who had immune system failure (RR 4.2 95% CI 0.93-18.94) and respiratory failure (RR 1.42 95% CI 0.88-2.29) although it did not reach significance. Cardiac failure remained constant (RR 0.84 95% CI 0.54-1.30).
  
  
  CONCLUSIONS
  The strict protocol approach based on the systemic evaluation of severely ill pregnant women with complications of hypertension and an intensive, regular feedback mechanism has been associated with a reduction in the number of patients with renal failure and cerebral compromise.
