Reducing unnecessary caesarean section in a district maternity unit
A district maternity hospital delivers 2,400 babies a year. The caesarean section rate rose from 21% to 34% over three years. Audit shows: 38% of primary caesareans were performed for "failure to progress" in the first stage; 22% of these women had a cervical dilatation recorded less than 2 hours before the decision; the unit has no written partogram policy and no dedicated labor ward coordinator on night shifts; electronic fetal monitoring is used for all admissions regardless of risk; and the induction rate is 31%, with 40% of inductions performed for post-term pregnancy at 41 weeks. The neonatal unit reports no increase in hypoxic-ischemic encephalopathy or low Apgar scores over the same period. The regional health authority has set a target of 25% by the end of next year.
1. Analyze the drivers of the rising caesarean rate and propose a prioritized package of interventions with measurable indicators.

The data suggest the rise is driven by practice patterns rather than by worsening maternal or fetal outcomes, since neonatal morbidity indicators are stable. Key drivers:
Inadequate diagnosis of labor arrest: 22% of "failure to progress" caesareans were decided less than 2 hours after the last cervical examination, which is inconsistent with accepted definitions of first-stage arrest requiring adequate contractions and no change over an adequate interval. This points to a diagnostic and documentation problem.
Absence of a partogram policy and of a labor ward coordinator at night, meaning decisions are made by the most junior available clinician without structured review.
Universal electronic fetal monitoring, which increases the detection of non-reassuring patterns of uncertain significance and therefore operative delivery, without proven benefit in low-risk women.
A high induction rate with many inductions at 41 weeks, which increases the chance of slow labor and subsequent caesarean.
Prioritized package:
Introduce a mandatory partogram with standard definitions of arrest, requiring a documented cervical examination within the preceding 2 hours and a second senior review before a caesarean for slow progress. Indicator: proportion of first-stage caesareans meeting the definition, target above 90%.
Appoint a labor ward coordinator for every shift, with a written escalation protocol. Indicator: documented senior review rate, and the caesarean rate by shift.
Restrict continuous electronic fetal monitoring to high-risk pregnancies and train staff in intermittent auscultation and in interpretation of cardiotocography. Indicator: proportion of low-risk women monitored intermittently.
Review induction practice: offer membrane sweeping and a planned date for induction at 41 weeks rather than routine earlier intervention, use validated Bishop score assessment and cervical ripening, and audit indications. Indicator: induction rate and the proportion of inductions at 41 weeks.
Provide regular audit and feedback with monthly case review of all primary caesareans, including a second-opinion log.
Ensure informed consent discussions and document the indication in the notes.
2. The caesarean rate falls to 27% after six months, but the unit reports two cases of severe postpartum hemorrhage and one case of suspected uterine rupture during trial of labor after previous caesarean. How do you respond?
Read the worked answer
A falling caesarean rate is not a success if it is achieved at the cost of maternal harm. The response must be a structured safety review, not a retreat to the previous rate.
First, review each case in a confidential, non-punitive morbidity and mortality meeting: was the trial of labor after caesarean appropriately selected and consented, was continuous monitoring in place, was there a documented plan for immediate operative delivery, and was the hemorrhage recognized and managed promptly with uterotonics, tranexamic acid, and blood products?
Second, strengthen the safety net around vaginal birth after caesarean: a written eligibility checklist, one-to-one midwifery care, immediate availability of theater and anesthesia, an escalation protocol for abnormal fetal heart rate, and a massive transfusion protocol. Ensure the unit has a clear threshold for abandoning trial of labor.
Third, check whether the fall in caesarean rate has shifted risk elsewhere - for example, more instrumental deliveries, more third- and fourth-degree tears, or more admissions to the neonatal unit. Compare these indicators with the baseline period.
Fourth, communicate transparently with the regional authority: report the safety indicators alongside the caesarean rate, and resist pressure to pursue the 25% target if safety signals persist. The target should be a direction of travel, not a hard quota.
Finally, provide debriefing and support to the staff involved, and consider simulation training in postpartum hemorrhage and uterine rupture.
