Antepartum bed rest for pregnancy complications: efficacy and safety for preventing preterm birth

Area of Science:

• Maternal-Child Health
• Obstetrics
• Perinatal Medicine

Background:

• Preterm birth is a leading cause of infant mortality and morbidity globally, with the U.S. rate significantly higher than in European countries.
• Antepartum bed rest/activity restriction (ABR/AR) has been a standard intervention for decades, despite limited evidence supporting its efficacy.
• Growing evidence suggests ABR/AR may lead to adverse physiological and psychological outcomes for both mothers and infants.

Purpose of the Study:

• To conduct an integrative literature review analyzing the evidence for ABR/AR in preventing preterm birth.
• To comprehensively examine the physiological, behavioral, and experiential side effects of ABR/AR.
• To propose a research model and explore alternative prenatal care models, such as home care with bed rest.

Main Methods:

• Integrative literature review.
• Analysis of existing evidence on ABR/AR efficacy and side effects.
• Literature search for alternative prenatal care models.

Main Results:

• The effectiveness of ABR/AR in preventing preterm birth is not supported by robust evidence.
• ABR/AR is associated with significant adverse physiological and psychological side effects for pregnant women and their infants.
• Alternative models like home care with bed rest show promise as safer and feasible options.

Conclusions:

• The widespread clinical practice of ABR/AR for preterm birth prevention requires reevaluation due to lack of evidence and potential harm.
• Further research is needed to understand the full impact of ABR/AR and to validate alternative prenatal care strategies.
• Implementing evidence-based, patient-centered care models is crucial for improving outcomes for high-risk pregnancies.
