Routine ultrasound in pregnancy

Area of Science:

• Obstetrics and Gynecology
• Medical Imaging
• Public Health

Background:

• Routine ultrasound in pregnancy is widely studied.
• Existing evidence lacks consistent findings on benefits and risks.
• Ultrasound screening for fetal anomalies raises concerns about accuracy and variability.

Purpose of the Study:

• To evaluate the benefits and risks of routine prenatal ultrasound.
• To assess the effectiveness of ultrasound screening for fetal anomalies.
• To understand the impact of ultrasound on perinatal outcomes and healthcare utilization.

Main Methods:

• Review of existing studies on routine ultrasound in pregnancy.
• Analysis of data regarding fetal risk, healthcare use, and health outcomes.
• Examination of screening performance for fetal anomalies, including interobserver variability.

Main Results:

• No consistent evidence of biological risk to the fetus from ultrasound.
• No consistent evidence of increased healthcare service use due to ascertained conditions.
• No consistent benefit in important health outcomes for routine ultrasound.
• Substantial concern regarding interobserver variability in screening for anomalies.
• Potential benefit of routine ultrasound in reducing perinatal deaths in specific populations.

Conclusions:

• Routine ultrasound does not demonstrate consistent benefits for major health outcomes.
• Ultrasound screening for anomalies requires significant skill, leading to variability.
• Targeted ultrasound screening, possibly informed by pretest counseling, may be more effective for specific populations.
• Further research is needed to demonstrate the effectiveness of routine ultrasound in improving health outcomes in the United States.
