Strengths and limitations:
Our study had several notable strengths. This was a large population study and the first study to address FCM in maternal trauma. The SZMC computerized database is updated in real time and further validated, hence minimizing any potential bias. In addition, during the study period, our department followed a strict indication protocol for performing FCM testing with a uniform decision-making process and obstetric practice for maternal trauma. Accordingly, our study is appropriate for generalization.
Our study had some limitations, mainly attributable to its retrospective design and inherent pitfalls. In this study, we did not include women with trauma during pregnancy in whom FCM test was not obtained. For many women, delivery information was not available in their medical files because they delivered in other medical centers. Nevertheless, when comparing maternal, pregnancy and trauma characteristics between those who delivered in our medical center and those who did not, we did not find major differences. A positive FCM was determined by our laboratory, however, it may be possible that only higher FCM is associated with adverse outcome.
In conclusion, in this retrospective cohort study FCM result was not related to adverse maternal or fetal/neonatal outcomes of women involved in minor trauma during pregnancy or their offspring. We suggest that FCM should not be routinely assessed in pregnant women involved in minor trauma, hence reducing patients’ and physicians’ unjustified expectations and the cost of care.
