Material methods This retrospective, population‐based included all deliveries Finland between 2004 2017 (n = 800 484). annual numbers diagnoses were gathered from nationwide Medical Birth Register Hospital Discharge Register. calculated subgroups according mode delivery, maternal diabetes status, body mass index (BMI), age, parity gestational age. Based on these numbers, tool created. Results overall 0.18%. It increased significantly during period 0.10% 0.32% ( P < .001). More specifically, analyzed except for women with BMI <18.5 or age <20 years. To importance factors, practical simple Instrumental vaginal any kind, ≥25, ≥40 years ≥41 weeks associated higher compared non‐diabetic, non‐obese younger spontaneous before 41 gestation. In our tool, cases had number points than those without it (15.2 vs 10.4, high when scores ≥18 (relative 9.54, 95% confidence interval 8.61‐10.57). Conclusions still low previous studies other countries. daily practice, new helps individual profile parturient. According highest found combination instrumental diabetes, weeks.
