| Popis: | To compare the use of simulator-based and patient-based obstetric ultrasound training.This was a prospective, randomized, single-blinded trial. Eighteen consenting obstetric trainees with minimal previous ultrasound exposure were recruited. Enrolled patients were also fully consenting. Mid-trimester fetal brain anatomy in the standard planes (i.e., biparietal diameter and head circumference, cavum septum pellucidum, posterior fossa, and lateral ventricle) was chosen as a surrogate for all fetal anatomy ultrasound training. Trainees were randomized into two groups according to training method: simulator group (n = 9) or patient group (n = 9). All participating trainees went through the following sequence: a didactic session regarding the required planes; a "real" patient 15-minute pretest; a 45-minute training session with a dedicated ultrasound educator, using either a simulator or a "real" patient (according to the randomized group assignment); and a 15-minute post-test to obtain and label the standard four planes on a "real" patient. All images were stored and then scored by two blinded Maternal Fetal Medicine staff, according to 3 set criteria: image quality, landmarks, and measurements. Each criterion was scored 0 to 15 for a total score of 0 to 60.Pretest competence was similar between the two groups. For each of the two groups there was a significant score improvement following training: real patient (mean score pretest 13.3 vs. post-test 24.6; P0.04) and simulator group (mean score pretest 15.9 vs. post-test 28.9; P0.05). All trainees demonstrated significant overall score improvements (mean score pretest 14.6 vs. post-test 26.6; P0.04) regardless of training method. Trainees were further divided by their initial level of confidence (pretest score ≤5: very unconfident; pretest5: unconfident). The improvement was similar for both groups, but "very unconfident" trainees' performance improved more in the simulator group (mean pretest vs. post-test score 3.5 to 35) compared with the patient group (mean pretest vs. post-test score 2.3 to 25.6) CONCLUSION: Simulator-based obstetric ultrasound training performed as well as real patient training and was found to be especially beneficial for beginner trainees. Simulator-based ultrasound training has a high rate of acceptance by trainees, does not require investment of patient or clinic resources, and warrants consideration as an educational tool for the safe and effective teaching of obstetric ultrasound. |
