Summary
This study inventoried outcomes from 63 studies comparing planned caesarean section (CS) and planned vaginal delivery (VD). Standardizing these outcomes will improve future research on planned birth modes.
Area of Science:
- Obstetrics and Gynecology
- Perinatal Research
- Evidence-Based Medicine
Background:
- Lack of consensus on reporting outcomes in planned mode of birth studies.
- Need for standardized outcome measures in caesarean section (CS) versus vaginal delivery (VD) comparisons.
Purpose of the Study:
- To develop an inventory of reported outcomes for studies comparing planned CS and planned VD.
- To establish a comprehensive list of outcome measures used in planned birth mode research.
Main Methods:
- Systematic review of prospective studies (2011-2019) comparing planned CS and planned VD.
- Inclusion criteria: singleton pregnancy, 37-40 weeks gestation, >100 participants, middle/high-income countries.
- Outcomes and measures extracted and organized using MOMENT criteria.
Main Results:
- Included 63 prospective studies with over 6.3 million women.
- Identified 43 primary outcomes and 79 primary outcome measures.
- Identified 12 secondary outcomes and 31 secondary outcome measures.
Conclusions:
- Findings will inform the development of a core outcome set for planned mode of birth.
- Standardizing outcomes will enhance comparison and interpretation of CS versus VD data.
- Aims to improve the quality and comparability of research on planned birth.
