Spontaneous haemoperitoneum in pregnancy: Nationwide surveillance and Delphi audit system.

OBJECTIVE: To evaluate the incidence, diagnostic management strategies and clinical outcomes of women with spontaneous haemoperitoneum in pregnancy (SHiP) and reassess the definition of SHiP. DESIGN: A population-based cohort study using the Netherlands Obstetric Surveillance System (NethOSS). SETTING: Nationwide, the Netherlands. POPULATION: All pregnant women between April 2016 and April 2018. METHODS: This is a case study of SHiP using the monthly registry reports of NethOSS. Complete anonymised case files were obtained. A newly introduced online Delphi audit system (DAS) was used to evaluate each case, to make recommendations on improving the management of SHiP and to propose a new definition of SHiP. MAIN OUTCOME MEASURES: Incidence and outcomes, lessons learned about clinical management and the critical appraisal of the current definition of SHiP. RESULTS: In total, 24 cases were reported. After a Delphi procedure, 14 cases were classified as SHiP. The nationwide incidence was 4.9 per 100 000 births. Endometriosis and conceiving after artificial reproductive techniques were identified as risk factors. No maternal and three perinatal deaths occurred. Based on the DAS, adequate imaging of free intra-abdominal fluid, and identifying and treating women with signs of hypovolemic shock could improve the early detection and management of SHiP. A revised definition of SHiP was proposed, excluding the need for surgical or radiological intervention. CONCLUSIONS: SHiP is a rare and easily misdiagnosed condition that is associated with high perinatal mortality. To improve care, better awareness among healthcare workers is needed. The DAS is a sufficient tool to audit maternal morbidity and mortality.

Variations across Europe in hospitalization and management of pregnant women with SARS-CoV-2 during the initial phase of the pandemic: Multi-national population-based cohort study using the International Network of Obstetric Survey Systems (INOSS).

INTRODUCTION: The majority of data on COVID-19 in pregnancy are not from sound population-based active surveillance systems. MATERIAL AND METHODS: We conducted a multi-national study of population-based national or regional prospective cohorts using standardized definitions within the International Network of Obstetric Survey systems (INOSS). From a source population of women giving birth between March 1 and August 31, 2020, we included pregnant women admitted to hospital with a positive SARS-CoV-2 PCR test ≤7 days prior to or during admission and up to 2 days after birth. The admissions were further categorized as COVID-19-related or non-COVID-19-related. The primary outcome of interest was incidence of COVID-19-related hospital admission. Secondary outcomes included severe maternal disease (ICU admission and mechanical ventilation) and COVID-19-directed medical treatment. RESULTS: In a source population of 816 628 maternities, a total of 2338 pregnant women were admitted with SARS-CoV-2; among them 940 (40%) were COVID-19-related admissions. The pooled incidence estimate for COVID-19-related admission was 0.59 (95% confidence interval 0.27-1.02) per 1000 maternities, with notable heterogeneity across countries (I2 = 97.3%, P = 0.00). In the COVID-19 admission group, between 8% and 17% of the women were admitted to intensive care, and 5%-13% needed mechanical ventilation. Thromboprophylaxis was the most frequent treatment given during COVID-19-related admission (range 14%-55%). Among 908 infants born to women in the COVID-19-related admission group, 5 (0.6%) stillbirths were reported. CONCLUSIONS: During the initial months of the pandemic, we found substantial variations in incidence of COVID-19-related admissions in nine European countries. Few pregnant women received COVID-19-directed medical treatment. Several barriers to rapid surveillance were identified. Investment in robust surveillance should be prioritized to prepare for future pandemics.

Lessons learned from the perinatal audit of uterine rupture in the Netherlands: A mixed-method study.

Background and Aims: To analyze outcomes of nationwide local audits of uterine rupture to draw lessons for clinical care. Methods: Descriptive cohort study. Critical incident audit sessions within all local perinatal cooperation groups in the Netherlands. Women who sustained uterine rupture between January 1st, 2017 and December 31st, 2019. Main Outcome Measures: Improvable factors, recommendations, and lessons learned for clinical care. Women's case histories were discussed in multidisciplinary perinatal audit sessions. Participants evaluated care against national and local clinical guidelines and common professional standards to identify improvable factors. Cases and outcomes were registered in a nationwide database. Results: One hundred and fourteen women who sustained uterine rupture were discussed in local perinatal audit sessions by 40-60 participants on average: A total of 111 (97%) were multiparous of whom 107 (94%) had given birth by cesarean section in a previous pregnancy. The audit revealed 178 improvable factors and 200 recommendations. Six percent (N = 11) of the improvable factors were identified as very likely and 18% (N = 32) as likely to have a relationship with the outcome or occurrence of uterine rupture. Improvable factors were related to inadequate communication, absent, or unclear documentation, delay in diagnosing the rupture, and suboptimal management of labor. Speak up in case a suspicion arises, escalating care by involving specialist obstetricians, addressing the importance of accurate documentation, and improving training related to fetal monitoring were the most frequent recommendations and should be topics for team (skills and drills) training. Conclusions: Through a nationwide incident audit of uterine rupture, we identified improvable factors related to communication, documentation, and organization of care. Lessons learned include "speaking up," improving the transfer of information and team training are crucial to reduce the incidence of uterine rupture.

Haptic Feedback, Force Feedback, and Force-Sensing in Simulation Training for Laparoscopy: A Systematic Overview.

OBJECTIVES: To provide a systematic overview of the literature assessing the value of haptic and force feedback in current simulators teaching laparoscopic surgical skills. DATA SOURCES: The databases of Pubmed, Cochrane, Embase, Web of Science, and Google Scholar were searched to retrieve relevant studies published until January 31st, 2017. The search included laparoscopic surgery, simulation, and haptic or force feedback and all relevant synonyms. METHODS: Duplicates were removed, and titles and abstracts screened. The remaining articles were subsequently screened full text and included in this review if they followed the inclusion criteria. A total of 2 types of feedback have been analyzed and will be discussed separately: haptic- and force feedback. RESULTS: A total of 4023 articles were found, of which 87 could be used in this review. A descriptive analysis of the data is provided. Results of the added value of haptic interface devices in virtual reality are variable. Haptic feedback is most important for more complex tasks. The interface devices do not require the highest level of fidelity. Haptic feedback leads to a shorter learning curve with a steadier upward trend. Concerning force feedback, force parameters are measured through force sensing systems in the instrument and/or the environment. These parameters, especially in combination with motion parameters, provide box trainers with an objective evaluation of laparoscopic skills. Feedback of force-use both real time and postpractice has been shown to improve training. CONCLUSIONS: Haptic feedback is added to virtual reality simulators to increase the fidelity and thereby improve training effect. Variable results have been found from adding haptic feedback. It is most important for more complex tasks, but results in only minor improvements for novice surgeons. Force parameters and force feedback in box trainers have been shown to improve training results.

Maternal cardiac arrest in the Netherlands: A nationwide surveillance study.

BACKGROUND: Maternal cardiac arrest is a complex and demanding clinical situation requiring a well-attuned team effort of healthcare workers of multiple disciplines. A recent report on maternal cardiac arrest in the United Kingdom reported a rise in incidence over a span of 10 years, while maternal mortality increased in the United States between 2000 and 2014. However, reported causes of maternal cardiac arrest differed between both countries. OBJECTIVE(S): To determine the incidence, causes and management of maternal cardiac arrest in the Netherlands and compare incidence with previous estimates in the Netherlands and the United Kingdom. STUDY DESIGN: Using the Netherlands Obstetric Surveillance System, all Dutch cases of maternal cardiac arrest during a three-year period (2013-2016) were prospectively collected. Complete casefile copies were obtained for analysis. Main outcome measures were incidence of maternal cardiac arrest and cardiac arrest in pregnancy, use of perimortem caesarean section if appropriate and maternal death. RESULTS: The monthly card return rate was 97%; 18 women with cardiac arrest during pregnancy and 20 postpartum met the inclusion criteria. Incidence of maternal cardiac arrest was 7.6 per 100,000 pregnancies and 3.6 per 100,000 pregnancies excluding postpartum maternal cardiac arrest. Main causes were pulmonary embolism (n = 9), major obstetric hemorrhage (n = 7) and amniotic fluid embolism (n = 6). Aortocaval compression relief and perimortem caesarean section were performed in 9/14 (29%) and 11/14 (79%) respectively in pregnancies 20 weeks gestational age onwards. Twenty-two women died, representing a case fatality rate of 58% (95% CI 42-72%). CONCLUSION(S): There is a higher incidence of cardiac arrest in pregnancy compared to both previous estimates in the Netherlands and recently established figures in the United Kingdom. Main causes of maternal cardiac arrest are potentially preventable and/or treatable complications of pregnancy. Insufficient use of critical elements of obstetric resuscitation identifies the need for enhanced obstetric emergency training for obstetric and non-obstetric first responders.

Training in Basic Laparoscopic Surgical Skills: Residents Opinion of the New Nintendo Wii-U Laparoscopic Simulator.

OBJECTIVE: Serious games are new in the field of laparoscopic surgical training. We evaluate the residents׳ opinion of a new laparoscopic simulator for the Nintendo Wii-U platform. DESIGN: Prospective questionnaire study. Participants received a standardized introduction and completed level 3 and 4 of the game "Underground." They filled out a questionnaire concerning demographics and their opinion on realism, usefulness, suitability, haptic feedback, and home training-use of the game. SETTING: Two tertiary teaching hospitals. PARTICIPANTS: Obstetrics and gynaecology residents postgraduate year 1 to 6 (n = 59) from several European countries. RESULTS: Subjects (n = 59) were divided into 2 groups based on laparoscopic experience: Group A (n = 38) and Group B (n = 21). The realism of different aspects of the game received mean scores around 3 on a 5-point Likert scale. The hand-eye coordination was regarded most useful for training with a mean of 3.92 (standard deviation 0.93) and the game was considered most suitable for residents in the first part of their postgraduate training with a mean of 3.73 (standard deviation 0.97). Both groups differed especially concerning their opinion of the usefulness of the game as a training tool. CONCLUSIONS: Most residents liked the new serious game for the Nintendo Wii-U. The usefulness and suitability as a laparoscopic training tool were rated at an acceptable to high level. However, the game does require improvements such as inclusion of a good scoring system before it can be integrated in resident training curricula.
