Fertility nurses doing embryo transfers -- what is the impact of training?
It has been demonstrated that embryo transfer during IVF treatment can be performed competently and successfully by nurses (Barber et al., 1996). The present study has examined the success of nurses in training using the standardized protocol of this Unit. Initially, three nurses (two experienced (training completed) and one inexperienced (training ongoing)) each performed 80 transfers, which were standardized to three embryos replaced per transfer. The study aimed to establish whether a standardized procedure was undertaken by the nurses and to assess the influence of one inexperienced nurse performing the procedure. A further study (study 2) was performed to assess the influence of three inexperienced nurses against three experienced nurses undertaking the same procedures. In study 1, the pregnancy rates were 27.5%, 38.8% and 40.0% and there was no significant difference in the clinical pregnancy rates. In study 2, the pregnancy rates were 18.7%, 20.0% and 20.0% for the inexperienced nurses, and 26.3%, 30.0% and 32.5% for the experienced nurses. There was no significant difference in the clinical pregnancy rates within the inexperienced group or the experienced group. When the results of the three inexperienced nurses were grouped and were compared with those of the three experienced nurses, the pregnancy rates were 19.5% and 29.5%, respectively (P < 0.02). It has been shown that good clinical pregnancy rates can be achieved when nurses perform embryo transfer. There is no significant effect on clinical results when one nurse is in training; however, because of the expected learning curve, when three nurses train together a more significant effect is observed.
