RT Journal Article T1 Variability and associated factors in the management of cord clamping and the milking practice among Spanish obstetric professionals A1 Ortiz Esquinas, Inmaculada A1 Gómez Salgado, Juan A1 Pascual Pedreño, Ana I. A1 Hernández Martínez, Antonio AB Clinical practice guides recommend delayed clamping of the umbilical cord. If this is not possible, someauthors suggest milking as an alternative. The objective of this study was to determine the variability inprofessional practice in the management of umbilical cord clamping and milking and to identify factorsor circumstances associated with the different methods. An observational cross-sectional study doneon 1,045 obstetrics professionals in Spain in 2018. A self-designed questionnaire was administeredonline. The main variables studied were type of clamping and use of milking. Crude odds ratios (OR)and adjusted odds ratios (ORa) were estimated using binary logistic regression. 92.2% (964) performeddelayed clamping. 69.3% (724) clamped the cord when it stopped beating. 83.8% (876) had heard ofmilking, and 55.9% (584) had never performed it. Professionals over 50 were less likely to performdelayed clamping, with an ORa of 0.24 (95% CI: 0.11–0.52), while midwives were more likely to performdelayed clamping than obstetricians, with an ORa of 14.05 (95% CI: 8.41–23.49). There is clinicalvariability in the management of umbilical cord clamping and the use of milking in normal births. Part ofthis variability can be attributed to professional and work environment factors.
