There were 4.6 million maternal stays in 2009.

Trauma to vulva and perineum due to childbirth was the most common condition in both 1997 and 2009 and the rate of this condition was similar between years.

The following maternal conditions increased from 1997 to 2009:

Maternal stay with previous C-section
Prolonged pregnancy
Hypertension complication pregnancy, childbirth and the puerperium

The following maternal conditions decreased from 1997 to 2009:

Normal pregnancy and/or delivery
