Conclusion
OASIs are still being missed by accouchers, and midwives failed to
identify 80% of OASIS. TPUS identified 91% of OASIs compared to 71%
detected by the accoucher suggesting that the detection rate with TPUS
may be better. However, TPUS requires specialist skills to perform and
interpret the images immediately after delivery and does not detect all
OASIS and therefore cannot be a substitute for training in clinical
diagnosis. More robust methods of education and assessment of competency
therefore need to be implemented for midwives and doctors to improve the
identification of OASIs.
