title: Risk Factors for Prolonged Postpartum Length of Stay Following Cesarean Delivery.
abstract: OBJECTIVE
  This study aims to identify risk factors for prolonged postpartum length of stays (LOS) after cesarean delivery (CD).
  
  
  METHODS
  Patients undergoing CD were sourced from a multicenter registry of 19 academic centers between 1999 and 2002 (n = 57,067). Prolonged postpartum LOS was defined as a hospitalization duration ≥ 90th centile. Maternal, antepartum, perioperative, and neonatal variables were compared between women with and without prolonged postpartum LOS.
  
  
  RESULTS
  The 90th centile for postpartum LOS was 4 days, with 14,954 women experiencing prolonged postpartum LOS. Women with perioperative complications had the highest independent risk for a prolonged postpartum LOS: ileus (adjusted odds ratio [aOR] = 12.28; 95% confidence interval CI = 8.98-16.8); endometritis (aOR = 10.45; 95% CI = 9.51-11.5), and wound complications (aOR = 5.49; 95% CI = 4.54-6.63). Several antepartum, perioperative, and neonatal variables were associated with a prolonged postpartum LOS.
  
  
  CONCLUSIONS
  Perioperative complications had the highest risk for prolonged LOS after CD. Strategies to reduce perioperative complications are needed to decrease the health care burden of prolonged post-CD LOS.
