Does the Use of Diagnostic Technology Reduce Fetal Mortality?

Area of Science:

• Obstetrics and Gynecology
• Medical Technology Assessment
• Public Health

Background:

• Fetal mortality rates have historically been a significant concern in obstetric care.
• The introduction of new diagnostic technologies aimed to improve fetal outcomes and reduce mortality.
• Understanding the impact of these technologies is crucial for evidence-based medical practice.

Purpose of the Study:

• To evaluate the effect of introducing new diagnostic technologies on fetal death rates.
• Specifically, to assess the impact of ultrasound and electronic fetal monitoring in obstetric care.
• To quantify the contribution of these technologies to changes in fetal mortality.

Main Methods:

• Utilized data from the Medical Birth Registry of Norway (1.2 million deliveries, 1967-1995).
• Employed hospital fixed-effects regression analysis with fetal mortality as the outcome.
• Key independent variables included the introduction of ultrasound and electronic fetal monitoring, controlling for hospital-specific trends and maternal risk factors.

Main Results:

• The introduction of ultrasound was associated with a significant reduction in the fetal mortality rate.
• Electronic fetal monitoring showed no significant effect on fetal mortality rates.
• Ultrasound technology contributed to an overall reduction of nearly 20 percent in fetal deaths, with over 50 percent reduction for post-term deliveries.

Conclusions:

• Ultrasound technology has made a major contribution to the decline in fetal mortality.
• The findings highlight the effectiveness of ultrasound as a diagnostic tool in improving fetal outcomes.
• The study underscores the importance of technological advancements in reducing fetal deaths in obstetric care.
