Also, the APNCU
Index only assesses adequacy of prenatal care utilization and does not provide information on the quality of the prenatal care that is delivered (Kotelchuck, 1994).
Furthermore, intensive use of prenatal care increased among both white (R-GINDEX, from 18% to 30%; APNCU, from 3% to 7%) and black women (R-GINDEX, from 20% to 31%; APNCU, from 4% to 7%).
White women had greater gains than black women in intensive use of prenatal care as measured by both the APNCU (68% vs.
First, the summary index for adequacy of prenatal care was developed using Kotelchuck's APNCU
CDHS defines APNCU as care initiated during the first 4 months of pregnancy, followed by [greater than or equal to]80% of the expected total number of visits recommended by the American College of Obstetricians and Gynecologists (ACOG), adjusted for the length of gestation (3).
During 1989-1994, rates of APNCU increased within all payment source categories.
9%; in contrast, the overall rate of APNCU increased 18.
If one's concern, however, is to inquire whether the timing effect of care initiation is linear or nonlinear, I then believe that employing the Kessner Index or the APNCU
adds little value to the use of the timing of care.
