Objective:
To describe the rates of percutaneous umbilical blood sampling(PUBS) training in United States Maternal Fetal Medicine (MFM) fellowships.
Study Design:
We performed an online survey of MFM fellows in all 3 years of fellowship regarding their PUBS training experience.
Results:
Of the 143 surveys, 87 (61%) were completed. The median number of PUBS performed was 1 (range 0-50) with a median of 5 (range 0-50) expected to be performed by fellowship completion. In all, 75 (86%) plan on performing PUBS after completion of fellowship. Of those, 53 (71%) do not expect to perform as many PUBS as they themselves consider the minimum number to achieve competency. There appears to regional variation in training opportunities.
Conclusion:
Training for PUBS in MFM fellowships appears to be limited in many portions of the country. Most fellows planning on performing PUBS in practice will not have performed the self-described minimum number needed for competence during fellowship.
