Triangulation of data
A narrative report was created for each case, combining all available data. This supported rapid analysis and cross-comparison between cases. Any issues that required clarification from the woman, operator, or midwife were highlighted during the creation of the report allowing them to be discussed during any subsequent interviews for the case in question and for all subsequent uses of the device. This enabled the development of key learning points or corrections to technique to be rapidly disseminated to the obstetricians.
