Summary
Cesarean delivery for fetal distress varies by institution and time of day. Nighttime deliveries showed increased rates, suggesting nonclinical factors like fatigue may influence diagnosis.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
Background:
- Cesarean section rates are influenced by institutional and practitioner factors.
- Understanding variations in cesarean delivery for fetal distress is crucial.
Purpose of the Study:
- To investigate if the diagnosis of fetal distress is influenced by time of day or institutional characteristics.
- To identify nonclinical factors affecting cesarean delivery rates for fetal distress.
Main Methods:
- Retrospective chart review of 6440 deliveries, excluding elective cesareans and inductions.
- Stratification by risk status, comparing cesarean deliveries for fetal distress with vaginal births.
- Analysis of delivery time, maternal socioeconomic factors, and obstetric variables.
Main Results:
- Significant institutional variation in cesarean delivery rates for fetal distress (0.9%–3.0%).
- Increased rates observed in nonwhite women and those with prior cesarean deliveries.
- Cesarean deliveries for fetal distress were significantly higher between 9:00 PM and 3:00 AM (aOR=1.56).
Conclusions:
- Cesarean delivery for fetal distress is influenced by institutional and nonclinical factors.
- Nighttime peaks in cesarean deliveries suggest potential impact of physician/patient fatigue on interpretation of fetal monitoring.
- Further research into nonclinical influences on obstetric decision-making is warranted.
