Abstract

Abstract Objective: To evaluate changes in overall and Robson group-specific cesarean section (CS) rates following implementation of a multifaceted institutional obstetric quality improvement strategy in a tertiary referral center. Methods: This single-center, retrospective, quasi-experimental before-and-after study included 13,595 deliveries: 11,238 before intervention (October 2023–November 2025) and 2,357 after intervention (December 2025–June 2026). The intervention integrated national clinical guidance into routine practice through multidisciplinary education, standardized labor management, assessment of failed induction, reassessment of fetal heart rate monitoring before CS, review of CS indications, strengthened midwifery involvement, and expanded antenatal education. Deliveries were classified using the Robson Ten-Group Classification System. Overall and group-specific CS rates were compared, with risk differences (RDs), relative risks (RRs), and 95% confidence intervals calculated. Results: The overall CS rate decreased significantly from 68.4% to 62.4% after intervention (RD, −6.0 percentage points; 95% CI, −8.1 to −3.9; RR, 0.91; 95% CI, 0.88–0.94; p<0.001). Significant reductions were observed in Robson Groups 1, 2, 3, 8, and 10. The largest reduction occurred in Group 3 (31.5% vs. 19.6%; RD, −11.9 percentage points; RR, 0.62; p<0.001). Group 5 remained the largest contributor to total cesarean deliveries. Conclusion: A multifaceted institutional quality improvement strategy was associated with a significant reduction in the overall CS rate and reductions in selected Robson groups. Robson-based audit may provide a practical framework for identifying target populations, evaluating obstetric practice changes, and supporting continuous quality improvement.

Özet

Özet Amaç: Üçüncü basamak bir referans merkezinde çok bileşenli kurumsal obstetrik kalite iyileştirme stratejisinin uygulanmasını takiben genel ve Robson gruplarına özgü sezaryen (CS) oranlarındaki değişiklikleri değerlendirmek. Yöntemler: Bu tek merkezli, retrospektif, yarı deneysel öncesi-sonrası çalışma 13.595 doğumu içermiştir: müdahale öncesinde (Ekim 2023–Kasım 2025) 11.238 ve müdahale sonrasında (Aralık 2025–Haziran 2026) 2.357 doğum. Müdahale; multidisipliner eğitim, standardize doğum eylemi yönetimi, başarısız indüksiyonun değerlendirilmesi, CS öncesinde fetal kalp hızı monitörizasyonunun yeniden değerlendirilmesi, CS endikasyonlarının gözden geçirilmesi, ebelik katılımının güçlendirilmesi ve antenatal eğitimin genişletilmesi yoluyla ulusal klinik rehberlerin rutin uygulamaya entegre edilmesini içermiştir. Doğumlar Robson On Gruplu Sınıflandırma Sistemi kullanılarak sınıflandırılmıştır. Genel ve gruplara özgü CS oranları karşılaştırılmış; risk farkları (RD), rölatif riskler (RR) ve %95 güven aralıkları hesaplanmıştır. Bulgular: Genel CS oranı müdahale sonrasında %68,4'ten %62,4'e anlamlı olarak azalmıştır (RD, −6,0 yüzde puan; %95 GA, −8,1 ila −3,9; RR, 0,91; %95 GA, 0,88–0,94; p<0,001). Robson Grup 1, 2, 3, 8 ve 10'da anlamlı azalmalar gözlenmiştir. En büyük azalma Grup 3'te gerçekleşmiştir (%31,5'e karşı %19,6; RD, −11,9 yüzde puan; RR, 0,62; p<0,001). Grup 5, toplam sezaryen doğumlara en büyük katkıyı sağlayan grup olmaya devam etmiştir. Sonuç: Çok bileşenli kurumsal kalite iyileştirme stratejisi, genel CS oranında anlamlı bir azalma ve seçilmiş Robson gruplarında azalmalar ile ilişkili bulunmuştur. Robson temelli denetim; hedef popülasyonların belirlenmesi, obstetrik uygulama değişikliklerinin değerlendirilmesi ve sürekli kalite iyileştirmenin desteklenmesi için pratik bir çerçeve sağlayabilir.
