Methods
Forty births were assisted with the Odon Device at North Bristol NHS
Trust, UK between October 2018 and January 2019. A case was defined as
the single use of the Odon Device and could contain data from one or
more of the following: formal observation of the Odon assisted birth, or
an interview with obstetricians, midwives or women involved in an Odon
assisted birth. Written consent was provided by all participants. Full
methods of the ASSIST Study have been published.
Case study methodology enabled the exploration and determination of
factors that improve optimal device use through bridging multiple
factors relating to the device – technique, design and parameters for
use (Figure 2).
