Objective:
To examine the association between health care services variables and pregnancy-related death using a contemporary geographically defined population and enhanced methods for case identification.
Methods:
This is a population-based, case-control study from North Carolina for the 7-year period 1992-1998. Pregnancy-related deaths after a live birth (n = 118) were identified after review of pregnancy-associated deaths (n = 400) ascertained from death certificate codes and linkage of birth and death files. Controls (n = 3697) were randomly selected from all registered live births for the same 7-year period and were not matched with cases. This sample size was sufficient to ensure that the standard errors for subgroup prevalences were less than 1%. The associations between pregnancy-related death and health care services were explored with univariate and multivariable regression analysis.
Results:
Neither maternity care coordination nor nutritional services were protective. There was no association with source of care, private versus public. The adjusted odds ratio (OR) for pregnancy-related death associated with cesarean delivery was 3.9 (95% confidence interval [CI] 2.5, 6.1). The adjusted OR for pregnancy-related death associated with the receipt of prenatal care was 0.2 (95% CI 0.1, 0.6).
Conclusion:
Removing barriers to and actively promoting use of prenatal care services and decreasing the rate of cesarean deliveries could decrease the number of pregnancy-related deaths.
