Abstract
INTRODUCTION AND HYPOTHESIS Obstetric anal sphincter injury (OASI) is a major complication associated with vacuum-assisted vaginal delivery (VAVD). The aim of this study was to evaluate risk factors related to vacuum extraction that are associated with OASI. METHODS This was a case-control study performed at a tertiary university teaching hospital. Included were patients aged 18-45 years who had a singleton pregnancy resulting in a live, term, VAVD. The study group consisted of women diagnosed with OASI following vacuum extraction. The control group included women following VAVD without OASI. Matching at a ratio of 1:2 was performed. Groups were compared regarding demographic, obstetric. and labor-related parameters, specifically focusing on variables related to the vacuum procedure itself. RESULTS One hundred and ten patients within the study group and 212 within the control group were included in the final analysis. Patients in the OASI group were more likely to undergo induction of labor, use of oxytocin during labor, increased second stage of labor, higher likelihood of the operator being a resident, increased number of pulls, procedure lasting under 10 min, occipito-posterior head position at vacuum initiation, episiotomy, increased neonatal head circumference, and birthweight. Multivariate logistic regression analysis revealed that increased week of gestation (OR 1.67, 95% CI 1.25-2.22, p < 0.001), unsupervised resident performing the procedure (OR 4.63, 95% CI 2.17-9.90), p < 0.001), indication of VAVD being fetal distress (OR 2.72, 95% CI 1.04-7.10, p = 0.041), and length of procedure under 10 min (OR 4.75, 95% CI 1.53-14.68, p = 0.007) were associated with OASI. Increased maternal age was associated with lower risk of OASI (OR 0.9, 95% CI 0.84-0.98, p = 0.012). CONCLUSIONS When performing VAVD, increased week of gestation, unsupervised resident performing the procedure, fetal distress as vacuum indication, and vacuum procedure under 10 min were associated with OASI. In contrast, increased maternal age was shown to be a protective factor.

SAGE Open Med 2024; 12:20503121241239813. [PMID: 38558771 PMCID: PMC10981216 DOI: 10.1177/20503121241239813] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Accepted: 02/29/2024] [Indexed: 04/04/2024] Open
Abstract
Objectives Recently, there has been a decline in the use of vacuums and forceps. This is due to complications that occur in the mother and baby as well as the operator's ability to operate the instruments. Concerning Professional Education Standards for Obstetrics and Gynecology Specialists, the minimum skill that must be achieved by vacuum extraction and forceps is a minimum of five cases. This is difficult to achieve with the number of obstetrics and gynecology residents in West Java. Methods A retrospective study was conducted using medical records based on the International Classification of Disease 10th Revision from 1 to 28 February 2023 at teaching hospitals and Academic Health System in West Java, namely Hasan Sadikin Hospital, Al-Ihsan Hospital Bandung, and Cikalong Wetan Hospital West Bandung, in the period 1 January 2018 to 31 December 2022. The main outcome was vacuum and forceps extraction with consecutive sampling. The relationship between maternal characteristics such as maternal age, parity, gestational age, and indication for delivery with vaginal operative delivery was descriptive statistics analyzed using IBM SPSS Statistics 26. Results Trends indicate that the percentage of vaginal operative deliveries tends to be low, below 5%. Vacuum deliveries decreased from 0.75% in 2018 to 0.68% in 2022, while forceps deliveries decreased from 2.77% to 0.98% over the same period. Conclusion This study concludes that there was an insufficiency of vacuum extraction and forceps delivery cases at the teaching hospital and Academic Health System in West Java to achieve a minimum case of vacuum and forceps. Further research studying how educational interventions improve operative delivery skills might be considered.

Developing the TeamOBS-vacuum-assisted delivery checklist to assess clinical performance in a vacuum-assisted delivery: a Delphi study with initial validation. Front Med (Lausanne) 2024; 11:1330443.

Abstract
Introduction In Northern Europe, vacuum-assisted delivery (VAD) accounts for 6-15% of all deliveries; VAD is considered safe when conducted by adequately trained personnel. However, failed vacuum extraction can be harmful to both the mother and child. Therefore, the clinical performance in VAD must be assessed to guide learning, determine a performance benchmark, and evaluate the quality to achieve an overall high performance. We were unable to identify a pre-existing tool for evaluating the clinical performance in real-life vacuum-assisted births. Objective We aimed to develop and validate a checklist for assessing the clinical performance in VAD. Methods We conducted a Delphi process, described as an interactive process where experts answer questions until answers converge toward a "joint opinion" (consensus). We invited international experts as Delphi panelists and reached a consensus after four Delphi rounds, described as follows: (1) the panelists were asked to add, remove, or suggest corrections to the preliminary list of items essential for evaluating clinical performance in VAD; (2) the panelists applied weights of clinical importance on a Likert scale of 1-5 for each item; (3) each panelist revised their original scores after reviewing a summary of the other panelists' scores and arguments; and (4) the TeamOBS-VAD was tested using videos of real-life VADs, and the Delphi panel made final adjustments and approved the checklist. Results Twelve Delphi panelists from the UK (n = 3), Norway (n = 2), Sweden (n = 3), Denmark (n = 3), and Iceland (n = 1) were included. After four Delphi rounds, the Delphi panel reached a consensus on the checklist items and scores. The TeamOBS-VAD checklist was tested using 60 videos of real-life vacuum extractions. The inter-rater agreement had an intraclass correlation coefficient (ICC) of 0.73; 95% confidence interval (95% CI) of [0.58, 0.83], and that for the average of two raters was ICC 0.84 95% CI [0.73, 0.91]. The TeamOBS-VAD score was not associated with difficulties in delivery, such as the number of contractions during vacuum extraction delivery, cephalic level, rotation, and position. Failed vacuum extraction occurred in 6% of the video deliveries, but none were associated with the teams with low clinical performance scores. Conclusion The TeamOBS-VAD checklist provides a valid and reliable evaluation of the clinical performance of vaginal-assisted vacuum extraction.

Abstract
OBJECTIVE To assess the effect of two modalities of simulation training on acquisition/retention of skills for performing operative vaginal delivery. DESIGN Randomized, controlled, single-centre study. SETTING A tertiary referral hospital in Italy. PARTICIPANTS Twenty residents from a single university programme and two young specialists. INTERVENTION Group 1 had an individual training session with a single senior specialist using a fixed simulator model. After the session, trainees watched a pre-recorded 1-h lecture on vacuum-assisted operative vaginal delivery. Group 1 repeated the simulator session using the same test after 8-12 weeks and 12 months. Group 2 watched the pre-recorded lecture then undertook the same sessions as Group 1. Video recordings of all test performances were evaluated by five specialists in a blinded manner. MAIN OUTCOME MEASURE Each procedure was evaluated using a Global Rating Scale (GRS), scored with 0-5 points for each item on an Objective Structured Assessment of Technical Skills (OSATS) dataset with seven items (total 35 points). OSATS were evaluated over time, compared for the whole population, and weighted for route and year of residency. The primary outcome was comparison of the effectiveness of training between the two groups based on year of residency by assessing videos of the baseline test and GRS for OSATS scores. The secondary outcome was overall retention of skills at 8-12 weeks and 12 months. RESULTS Twenty-two participants were recruited and randomized to either Group 1 (n = 11) or Group 2 (n = 11). Five participants did not complete follow-up. The primary outcome of GRS for OSATS scores at time 0 differed significantly between groups for total GRS score, and 'Call for help' and 'Explanation to woman and relatives' item scores (p = 0.002 and p = 0.007, respectively). In a multiple linear regression analysis, OSATS scores were not independently influenced by year of residency. At 8-12-week follow-up, the 'Call for help' item score showed a significant improvement in Group 1 (p = 0.018), although this was not confirmed when year of residency was included as an independent variable. At 12-month follow-up, none of the item scores demonstrated a significant change (p = 0.033). Year of residency did not influence the difference between groups. One-way analysis of variance found significant differences between the groups for 'Localization of the flexion point' (p = 0.005), 'Traction of vacuum cup' (p = 0.039) and 'Use of second hand of the operator' (p = 0.009) item scores and total GRS score (p = 0.007). The values weighted by year of residency did not demonstrate any significant difference. The secondary outcomes evaluated all the candidates of both groups for retention of technical skills over time. A significant effect of time was found for total GRS score (p < 0.001) and OSATS item scores. CONCLUSIONS Independent of the sequence of theoretical teaching and simulation training, trainees demonstrated high retention - and, actually, improvement - of technical skills for operative vaginal delivery at 12-month follow-up.

Abstract
OBJECTIVE To examine clinical and physician factors associated with failed operative vaginal delivery among individuals with nulliparous, term, singleton, vertex (NTSV) births. METHODS This was a retrospective cohort study of individuals with NTSV live births with an attempted operative vaginal delivery by a physician between 2016 and 2020 in California. The primary outcome was cesarean birth after failed operative vaginal delivery, identified using linked diagnosis codes, birth certificates, and physician licensing board data stratified by device type (vacuum or forceps). Clinical and physician-level exposures were selected a priori, defined using validated indices, and compared between successful and failed operative vaginal delivery attempts. Physician experience with operative vaginal delivery was estimated by calculating the number of operative vaginal delivery attempts made per physician during the study period. Multivariable mixed effects Poisson regression models with robust standard errors were used to estimate risk ratios of failed operative vaginal delivery for each exposure, adjusted for potential confounders. RESULTS Of 47,973 eligible operative vaginal delivery attempts, 93.2% used vacuum and 6.8% used forceps. Of all operative vaginal delivery attempts, 1,820 (3.8%) failed; the success rate was 97.3% for vacuum attempts and 82.4% for forceps attempts. Failed operative vaginal deliveries were more likely with older patient age, higher body mass index, obstructed labor, and neonatal birth weight more than 4,000 g. Between 2016 and 2020, physicians who attempted more operative vaginal deliveries were less likely to fail. When vacuum attempts were successful, physicians who conducted them had a median of 45 vacuum attempts during the study period, compared with 27 attempts when vacuum attempts were unsuccessful (adjusted risk ratio [aRR] 0.95, 95% CI 0.93-0.96). When forceps attempts were successful, physicians who conducted them had a median of 19 forceps attempts, compared with 11 attempts when forceps attempts were unsuccessful (aRR 0.76, 95% CI 0.64-0.91). CONCLUSION In this large, contemporary cohort with NTSV births, several clinical factors were associated with operative vaginal delivery failure. Physician experience was associated with operative vaginal delivery success, more notably for forceps attempts. These results may provide guidance for physician training in maintenance of operative vaginal delivery skills.

Abstract
OBJECTIVE The scope of this work is to evaluate an operative protocol for emergency C-section to improve teamwork and reduce surgical setup time. METHODS Sixty-six health care operators working together in the delivery ward (gynecologists, midwives, anesthesiologists) simulated an emergency scenario applying a "five actions for each operator" protocol. For each simulation, the decision to delivery interval was considered and the perception of each operator as a team worker was analyzed with specific tests. RESULTS The "five actions for five people" protocol significantly reduces the decision to delivery interval (p < 0.001) for emergency C-section. At the same time, a simple and codified scheme improves communication among team members, avoids overlapping roles. Indeed, all the operators become more aware of being helpful to the team (p < 0.001). CONCLUSION The use of a standardized, simple, and immediately usable protocol improves the performance of the delivery room team in terms of the urgency and quality of the operator's participation in the event. Procedures of this type should be favored within emergency obstetric settings. TRIAL REGISTRATION NUMBER CEAVNO 19-01-23. Local ethical Committee (COMITATO ETICO REGIONALE PER LA SPERIMENTAZIONE CLINICA - Sezione autonoma Area Vasta Nord Ovest -CEAVNO) approved this study as simulation training study. All the operators participated voluntary during their working time.

Abstract
The pathophysiologic origins of obstetrical emergencies are complicated and may well be influenced by events prior to conception. Such problems are not likely to be resolved soon, and in the meantime, high-resource countries simply cannot afford to divert more and more money to litigation and the costs of preventable morbidities for either mother or child. It is long past time we tackled these acute care problems where most first occur-the Maternity unit. It is reasonable to ask whether hospitals (and society at large) are getting what they believe they are buying. Training to satisfy a regulation without improving patient outcomes functionally erects one more barrier to the pursuit of optimal patient outcomes. Why then continue squandering limited resources and precious lives if current hospital training is not improving outcomes? In this monograph, I focus on training programs for the management of obstetrical emergencies.

Abstract
Effective training in operative birth should be the only type of operative birth that trains the junior obstetricians who are exposed to it. Although it remains difficult to fully characterise, effective training in operative birth is likely to include (i) realistic, local, integrated simulation training and (ii) hands-on senior support for an extended period of time. To further improve skills training in operative birth, an evaluation of the real-world effectiveness of current training should take place, a core outcome set for clinical trials should be developed, and real-time reporting and tracking of practitioner-specific outcome measures should be implemented.
