Routine obstetric ultrasound services.

Area of Science:

• Medical Imaging
• Obstetrics and Gynecology
• Public Health

Background:

• Antenatal ultrasonography is crucial for assessing fetal development and anatomy during pregnancy.
• While common in many countries, obstetric ultrasound practice recommendations vary internationally.
• Ireland currently lacks national guidelines for minimum standards in obstetric ultrasound.

Purpose of the Study:

• To survey current obstetric ultrasound practices in Irish maternity units.
• To identify variations in mid-trimester anomaly scanning and fetal anatomical survey protocols.
• To highlight the need for national guidelines and improved resources in Irish obstetric ultrasound services.

Main Methods:

• A structured telephone survey was conducted in 2012 across all 20 maternity units in Ireland.
• Data collected included the availability of routine mid-trimester anomaly scans, time allocated for fetal surveys, use of guidelines for soft markers, and image review practices.
• Survey responses were analyzed to determine current standards and identify areas for improvement.

Main Results:

• Routine mid-trimester anomaly scanning was not universally offered, with 20% of units not providing it at all.
• Time allocated for fetal anatomical surveys varied, with many units falling short of recommended durations.
• Written guidelines for soft markers were used in 69% of units, but image review by fetal medicine specialists was absent in all units.
• 95% of respondents believed a minimum of two scans should be offered in routine pregnancies.

Conclusions:

• There is a significant disparity in the provision and standards of obstetric ultrasound across Irish maternity units.
• The findings underscore an urgent need for national guidelines to standardize practice and ensure equitable care.
• Increased staffing for ultrasonographers and fetal medicine specialists is essential to improve obstetric ultrasound services in Ireland.
