Delivery Hospital Characteristics and Postpartum Maternal Mortality: A National Case-Control Study in France
Abstract
BACKGROUND
The variability in resources for managing critical events among maternity hospitals may impact maternal safety. Our main objective was to assess the risk of postpartum maternal death according to hospitals' organizational characteristics. A secondary objective aimed to assess the specific risk of death due to postpartum hemorrhage (PPH).
METHODS
This national population-based case-control study included all 2007-2009 postpartum maternal deaths from the national confidential enquiry (n= 147 cases) and a 2010 national representative sample of parturients (n = 14,639 controls). To adjust for referral bias, cases were classified by time when the condition/complication responsible for the death occurred: postpartum maternal deaths due to conditions present before delivery (n = 66) or during or after delivery (n = 81). Characteristics of delivery hospitals included 24/7 on-site availability of an anesthesiologist and an obstetrician, level of perinatal care, number of deliveries annually, and their teaching and profit status. In teaching and other nonprofit hospitals in France, obstetric care is organized on the principle of collective team-based management, while in for-profit hospitals, this organization is based mostly on that of "one woman-one doctor." Logistic regression models were used to estimate adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for postpartum maternal death.
RESULTS
The risk of maternal death from prepartum conditions was lower for…
How strong is the evidence?
Evidence Hub reads this as a case-control, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 14,639 participants or records.
