The majority of the population living in rural areas has limited access to essential obstetric care, therefore the frequency of life threatening obstetric complications including rupture of uterus
is higher in these nations5.
Suspected cases were defined as women discharged from Massachusetts hospitals from 1990 through 1997 with an ICD-9-CM diagnostic code in any of the 10 diagnostic fields of 665.0 ("rupture of uterus
before onset of labor"), 665.1 ("rupture of uterus
during labor," including "rupture of uterus
not otherwise specified"), or 674.1 ("disruption of cesarean wound," including "dehiscence or disruption of uterine wound").
