PHOM Indicator Profile Report of Preterm Birth

Why Is This Important?

Preterm birth, birth before 37 weeks gestation, is the leading cause of perinatal death in otherwise normal newborns and is a leading cause of long-term neurological disabilities in children. Infants born before 32 weeks gestation bear the biggest burden representing more than 50 percent of infant deaths. Babies born preterm also have increased risks for long term morbidities and often require intensive care after birth. Health care costs and length of hospital stay are higher for premature infants. For a preterm infant without complications, average hospital stays are three times longer than a term infant, and for a preterm infant with complications, average hospital stays are over seven times longer than a term infant. Utah inpatient hospital discharge data (2016) indicate that average hospital charges for a premature infant was $73,498 (DRG 790, 791, 792) compared to $3,283 for a normal newborn infant (DRG 795). Utah inpatient hospital discharge data (2016) indicate that average length of stay for a premature infant was 16 days (DRG 790, 791, 792) compared to 1.8 days for a normal newborn infant (DRG 795).

Data Notes

2017 U.S. data is final. U.S. data prior to 2010 is based on gestational age from last menstrual period (LMP) versus gestation based on the obstetric estimate. U.S. data of gestation based on the obstetric estimate has been revised back to 2010. Utah data is calculated by obstetric estimate. Beginning in 2010, national rates are reported using OE and are not consistent with rates reported before 2010.

Risk Factors

2017 data show the following risk factors contribute to having a preterm birth: *Previous preterm births *Pre-pregnancy BMI (obese prior to pregnancy) *Intervals less than 6 months between pregnancies or > 48 months *Multiple gestation (e.g. twins) *Tobacco use during pregnancy *Maternal chronic disease, such as hypertension or diabetes

How Are We Doing?

Utah's preterm birth rate increased from 8.8% in 1990 to a high of 10.1% in 2005. The rate has remained under 10% from 2006 to 2017. The Utah preterm birth rate decreased to 9.4% in 2017.

What Is Being Done?

Approximately half of preterm births in Utah are due to complications of the pregnancy (multiple births, placental problems, fetal distress, infections) or maternal health factors such as high blood pressure or uterine malformations. The remaining preterm births have unexplained causes. In an effort to reduce the preterm birth rate, emphasis is being placed on maternal preconception health to help women achieve optimal health prior to pregnancy. Some ways women can achieve optimal health include stopping use of tobacco and alcohol, controlling chronic diseases such as diabetes and high blood pressure under control, and obtaining an optimal pre-pregnancy weight. Early and continuous prenatal care is encouraged to detect problems that may arise during pregnancy. Women should be educated regarding the danger signs of pregnancy and the importance of recognition and treatment for these symptoms. Standards for assisted reproductive technology should be followed to reduce the frequency of twins or higher order multiple pregnancies. Pregnant women should also be referred for appropriate services such as Women, Infant and Children (WIC) and psychosocial counseling. Studies have demonstrated a substantial reduction in the rate of recurrent preterm birth in women receiving progesterone supplementation. Pregnant women who have had a previous spontaneous preterm birth, particularly in the immediately preceding pregnancy, should be offered progesterone supplement beginning at 16-20 weeks gestation. Women pregnant with twins or triplets may not benefit from this medication. The maternal committee of the Utah Women and Newborns Quality Collaborative (UWNQC) ([]) has identified optimization of 17 alpha hydroxyprogesteronecaproate (17P) use to prevent recurrent spontaneous preterm birth (SPTB) in women with a previous history of SPTB as the primary focus of their efforts. This group has developed a series of videos on preterm birth prevention and is working to educate providers on the use of 17P. The committee has produced matarials to help educate families who have delivered prematurely on what they can do to reduce the chances of preterm birth from happening in future pregnancies. In addition, the maternal committee has worked on access to immediate postpartum long-acting reversible contraception as well as other family planning access.
