Quantitative data and analysis
Quantitative data included recruitment figures, demographic data, fidelity criteria and neonatal admissions. Fidelity criteria for this portion of the study included: attendance of someone who completed the OptiBreech training package; attendance of someone who met the full proficiency criteria; whether or not maternal movement and effort were used as a first intervention before hands-on assistance; whether or not the birth was complete within five minutes of the birth of the fetal pelvis; and maternal birthing position. To achieve full proficiency, as defined in this trial, the professional needed to have completed the training package; attended at least 10 births including complications; attended 3 births within the past year; and contribute to teaching and reflective reviews of births attended. This is assessed by the breech leads, one of whom was also the Principal Investigator (PI) at each local site. All quantitative data was obtained from individual Case Report Forms completed by local investigators and analysed descriptively.
