The Development And Pilot Evaluation Of An Out-Of-Hospital Immersive Birthing Simulation Training Application For Paramedics And Ambulance Officers Using Virtual-Reality Technology, Michella Hill

Theses: Doctorates and Masters

Out-of-hospital births (OOHBs) are births which occur outside a hospital setting. This includes planned home births attended by midwives, or unplanned OOHBs where the intention was to birth in a hospital or maternity centre, however, occurs in an unintended location. Prehospital clinicians, inclusive of registered paramedics and volunteer ambulance officers (VAOs) infrequently attend OOHBs, as most births occur in maternity wards as anticipated. OOHBs comprises < 1% of emergency ambulance requests and requires specialised skills for prehospital clinicians to competently manage birthing and potential complications. As exposure to birthing is so rare, these specialised skills and knowledge are underutilised and subject to rapid decay. Compounding the problem, obstetrics is infrequently taught across undergraduate education, in-service training, or within individual clinician’s continuing professional development. Placements shadowing midwives are scarce due to nursing and medical students receiving priority. Previous research regarding OOHBs is limited, nonetheless suggests prehospital clinicians are underprepared to manage an OOHB, which has serious patient safety implications. The present research sought to explore prehospital clinicians’ preparedness and confidence in managing OOHBs. It also investigates whether a digital training solution such as virtual reality (VR) simulation may reduce the theory-practice gap and assist in competency retention.

Publication one provides a comprehensive methodology outline which is applied to Study One; a scoping review of prehospital clinician and birth parent experiences with OOHBs. Risk factors, complications and interventions provided by prehospital clinicians, as …

A Fully Discrete Semi-Implicit Numerical Scheme And Its Optimal Error Estimates For Cahn-Hilliard-Mhd Model With Variable Density, Dongmei Duan, Fuzheng Gao, Xiaoming He, Yanping Lin

Mathematics and Statistics Faculty Research & Creative Works

This paper proposes and analyzes a fully discrete semi-implicit unconditionally energy stable numerical scheme to solve the Cahn-Hilliard Magnetohydrodynamics (Cahn-Hilliard-MHD) model with variable density. The unconditional energy stability and optimal L² error estimates are established for the fully discrete scheme. Major challenges in error estimation arise from the variable density, the strong nonlinearities, and the multi-physics coupling of the model. Under the mathematical induction framework, the Ritz quasi-projection and the Stokes quasi-projection, proposed in [SIAM J. Numer. Anal., 61(3):1218-1245, 2023], are utilized to avoid the gradient terms of the projection errors. The H⁻¹ superconvergence error estimates of Ritz …
