Comparison of a practice-based versus theory-based training program for conducting vacuum-assisted deliveries: a randomized-controlled trial

Abstract

Purpose Vacuum-assisted deliveries (VAD) are complex procedures that require training and experience to be performed proficiently. We aimed to evaluate if a more resource intensive practice-based training program for conducting VAD is more efficient compared to a purely theory-based training program, with respect to immediate training effects and persistence of skills 4–8 weeks after the initial training. Methods In this randomized-controlled study conducted in maternity staff, participants performed a simulated low-cavity non-rotational vacuum delivery before (baseline test) and immediately after the training (first post-training test) as well as 4–8 weeks thereafter (second post-training test). The study’s primary endpoint was to compare training effectiveness between the two study groups using a validated objective structured assessment of technical skills (OSATS) rating scale. Results Sixty-two participants were randomized to either the theory-based group (n = 31) or the practice-based group (n = 31). Total global and specific OSATS scores, as well as distance of cup application to the flexion point improved significantly from baseline test to the first post-training test in both groups (pall < 0.007). Skill deterioration after 4–8 weeks was only found in the theory-based group, whereas skills remained stable in the practice-based group. Conclusion A practice-based training program for conducting VAD results in comparable immediate improvement of skills compared to a theory-based training program, but the retention of skills 4–8 weeks after training is superior in a practice-based program. Future studies need to evaluate, whether VAD simulation training improves maternal and neonatal outcome after VAD.

The Axiology Aspect should be Encouraged, Not the Jargon as Kampung Inggris Sawai

“…The first is fostering the inquiry process, and the second should aim at skill exposure. Marschalek et al (2022) the idea, as shown in (QSI INTERNATIONAL SCHOOL OF YEREVAN, n.d.), for the English language focus of an intensive program, the output of participants and course content should be shaped as in the following figure below. Based on past studies, this research aimed to extend the examination of community service reports in Sawai Village, North Seram, The Regency of Central Maluku, Maluku Province, Indonesia, since 2021.…”
