A national survey of clinicians' opinions of rotational vaginal births.

INTRODUCTION: Malposition of the fetal head, defined as occiput transverse or posterior positions, occurs in approximately 5% of births. At full cervical dilatation, fetal malposition is associated with an increased risk of rotational vaginal birth. There are three different rotational methods: manual rotation, rotational ventouse or rotational (Kielland's) forceps. In the absence of robust evidence, it is not currently known which of the three methods is most efficacious, and safest for parents and babies. OBJECTIVE: To gain greater insights into opinions and preferences of rotational birth to explore the acceptability and feasibility of performing a randomised trial comparing different rotational methods. MATERIAL AND METHODS: A survey was sent via email to obstetricians from the British Maternal Fetal Medicine Society, as well as expert obstetricians and active academics in ongoing research in the UK. The questions focussed on perceived competence, preferred rotational method, location (theatre or labour room), willingness to recruit to an RCT, and its outcome measures. Closed questions were followed by the option of free text to allow further comments. The free text answers underwent thematic analysis. RESULTS: 252 consultant obstetricians responded. The majority stated they were competent in performing manual rotation (88.1%). Half felt proficient using Kielland's rotational forceps (54.4%). Most obstetricians felt skilled in rotational ventouse (76.2%). Manual rotation was the preferred first rotational method of choice in cases of both occiput transverse and posterior positions. The decision for which rotational method to attempt first was considered case-dependent by many. Two thirds of obstetricians would usually conduct rotational births in theatre (67.9%). Over half (52%) do not routinely use intrapartum ultrasound. Most (62.7%) would be willing to recruit to a randomised controlled trial comparing manual versus instrumental rotation. Over half (57.2%) would be willing to recruit to the same RCT if they were the most senior doctor competent in rotational vaginal birth supervising a junior. CONCLUSION: There is a wide range of practice in conducting rotational vaginal births in the UK. An RCT to investigate the impact of different rotational methods on outcome would be both feasible and desirable, especially in research-active hospitals.

A new course on assisted rotational birth and complex caesarean section - Mixed methods evaluation of Art & Craft.

OBJECTIVES: To assess the utility of Art & Craft - a new, hands-on course on Advanced Rotational Techniques and safe Caesarean biRth at Advanced/Full dilation Training aimed at senior Obstetrics trainees. The aims were to assess whether it improved confidence and skills in rotational vaginal birth, impacted fetal head at caesarean, and ultrasound for fetal position. STUDY DESIGN: With ethical approval, pre- and post- course questionnaires and post- course interviews of attendees were conducted. A pre course questionnaire was emailed 1 week before the course. Attendees were asked to rate their confidence levels in performing vaginal examination and ultrasound assessment of fetal position, rotational ventouse, manual rotation, Kielland's rotational forceps, and disimpaction of the fetal head during second stage caesarean on a scale of 1 to 5. 1 = not confident at all and 5 = very confident. A post-course questionnaire with the same questions was emailed 3 days after. p values for differences in scores were calculated using the Wilcoxon signed rank test using Stata/MP 18 software. RESULTS: 32 trainees attended the course. 28 questionnaires were available for analysis. The majority 39 % were middle grade (ST3-ST5) level. Initial confidence was very low for rotational forceps (median 1/5). After attending the course and practical stations, respondents' confidence levels increased significantly (p < 0.05) across all domains; vaginal examination from 4 to 5, ultrasound for fetal position, rotational ventouse, and manual rotation from 3 to 5, disimpaction from 4 to 4.5, and Kielland's rotational forceps from 1 to 4. Nine participated in post course interviews, which were thematically analysed. Participants expressed that the course gave them the opportunity to ask specific questions from experts to improve their confidence. A barrier to learning new methods was highlighted in that it is difficult to receive practical training in Kielland's, resulting in low confidence. CONCLUSION: A practical, hands-on course on complex operative birth significantly increases trainee confidence levels in vaginal examination, ultrasound for fetal position, disimpaction, and techniques for rotational vaginal birth. The evaluation highlights that continued education and practise is required, even when trainees are senior. Evaluation of clinical outcomes after training is needed; and planned.

Requirements for a Dashboard to Support Quality Improvement Teams in Pain Management.

Pain management is often considered lower priority than many other aspects of health management in hospitals. However, there is potential for Quality Improvement (QI) teams to improve pain management by visualising and exploring pain data sets. Although dashboards are already used by QI teams in hospitals, there is limited evidence of teams accessing visualisations to support their decision making. This study aims to identify the needs of the QI team in a UK Critical Care Unit (CCU) and develop dashboards that visualise longitudinal data on the efficacy of patient pain management to assist the team in making informed decisions to improve pain management within the CCU. This research is based on an analysis of transcripts of interviews with healthcare professionals with a variety of roles in the CCU and their evaluation of probes. We identified two key uses of pain data: direct patient care (focusing on individual patient data) and QI (aggregating data across the CCU and over time); in this paper, we focus on the QI role. We have identified how CCU staff currently interpret information and determine what supplementary information can better inform their decision making and support sensemaking. From these, a set of data visualisations has been proposed, for integration with the hospital electronic health record. These visualisations are being iteratively refined in collaboration with CCU staff and technical staff responsible for maintaining the electronic health record. The paper presents user requirements for QI in pain management and a set of visualisations, including the design rationale behind the various methods proposed for visualising and exploring pain data using dashboards.

Are fiducial registration error and target registration error correlated? SciKit-SurgeryFRED for teaching and research.

Understanding the relationship between fiducial registration error (FRE) and target registration error (TRE) is important for the correct use of interventional guidance systems. Whilst it is well established that TRE is statistically independent of FRE, system users still struggle against the intuitive assumption that a low FRE indicates a low TRE. We present the SciKit-Surgery Fiducial Registration Educational Demonstrator and describe its use. SciKit-SurgeryFRED was developed to enable remote teaching of key concepts in image registration. SciKit-SurgeryFRED also supports research into user interface design for image registration systems. SciKit-SurgeryFRED can be used to enable remote tutorials covering the statistics relevant to image guided interventions. Students are able to place fiducial markers on pre and intra-operative images and observe the effects of changes in marker geometry, marker count, and fiducial localisation error on TRE and FRE. SciKit-SurgeryFRED also calculates statistical measures for the expected values of TRE and FRE. Because many registrations can be performed quickly the students can then explore potential correlations between the different statistics. SciKit-SurgeryFRED also implements a registration based game, where participants are rewarded for complete treatment of a clinical target, whilst minimising the treatment margin. We used this game to perform a remote study on registration and simulated ablation, measuring how user performance changes depending on what error statistics are made available. The results support the assumption that knowing the exact value of target registration error leads to better treatment. Display of other statistics did not have a significant impact on the treatment performance.
