Introduction: :
Obstetric anal sphincter injuries (OASIS) refer to third- or fourth-degree perineal trauma after childbirth, and it is the primary cause of faecal incontinence, affecting about 5.7% of primiparous women following vaginal births. Accurate detection of perineal tear following delivery allows prompt management and it is a significant midwifery skill yet clinical training seems inconsistent across different hospitals. Therefore, there is need for a standardized and accessible training to improve the competency and confidence among student midwives.
Objectives: :
- To improve the competency and confidence of student midwives in accurately detecting and classifying perineal tears following vaginal delivery.
- To integrate the 3D animated video into the core midwifery training curriculum to ensure consistent and high-quality demonstration of OASIS assessment.
- To promote women-centered care and clinical safety by supporting accurate early diagnosis of OASIS, thereby facilitating prompt management and improving patient outcomes.
Methodology: :
We developed an innovative educational tool in the School of Midwifery, starting with script development based on current clinical guidelines, followed by creation of 3D anatomical models to visualize pelvic floor structures, step-by-step procedural animation for OASIS assessment, and the final version is reviewed and validated by obstetrician expert to ensure its accuracy.
Result & Outcome: :
A high-quality 3D animated video (approximately 1.5 minutes) is produced which simplifies complex concepts of pelvic floor anatomy and demonstrates systematic examination for OASIS for the audience. This video will be integrated to the training curriculum for student midwives and made accessible to both practising midwives and medical students, ensuring accurate and consistent demonstration of such an important technique. A structured evaluation of its impacts on students’ competency and confidence will be conducted.
This 3D animated training video represents a significant milestone in midwifery education in advocating for and promoting women-centred care. It standardizes a core clinical skill for midwives and midwife-to-be to improve the accuracy of OASIS diagnosis for new mothers following normal vaginal deliveries. This project also exemplifies teamwork and innovation in addressing a clinical training gap. We propose this as an effective, scalable tool for improving clinical safety, quality of service, and staff competency in OASIS assessment across the Hospital Authority.
