The Impact of Bariatric Surgery on Assisted Reproductive Technology Outcomes: A Systematic Review.

OBJECTIVE: There is a paucity of literature on the impact of bariatric surgery on artificial reproductive technology (ART) outcomes. This topic should be examined, given that most bariatric surgery candidates are of reproductive age and those with obesity are significantly more likely to experience poor fertility outcomes. This systematic review aimed to determine if bariatric surgery impacts ART outcomes and if effects vary between females and males. DATA SOURCES: MEDLINE, EMBASE, SCOPUS, and the Cochrane Central Register of Controlled Trials were searched for English studies published between January 1978 and May 2021. STUDY SELECTION: Studies with participants who had received bariatric surgery and subsequently underwent ART (i.e., in vitro fertilization or intracytoplasmic sperm injection) were eligible for inclusion. Screening, data abstraction, and risk of bias assessment were conducted independently and in duplicate. DATA EXTRACTION AND SYNTHESIS: Of the 279 articles screened for eligibility, 25 were sought for full text review, and 7 were included for analysis. Four studies (57%) examined ART interventions in females, while 3 (43%) examined interventions in males. Data on cumulative live birth rate (CLBR) was extracted for all 7 studies (N = 169). There were 50 live births with CLBRs ranging from 0.0% to 80.0%. Data on female secondary outcomes were varied. Data on male secondary outcomes were contradictory: 1 study indicated improved sperm parameters following bariatric surgery, while 2 showed decreased parameters, with certain participants seeing improvements after several months. CONCLUSION: Bariatric surgery prior to ART may have an impact on CLBRs; however, high-quality research is needed to delineate the direct effects of bariatric surgery on ART outcomes. Various sex-specific outcomes should be considered prior to recommending ART after bariatric surgery. Future research should determine the optimal type of bariatric surgery and timing of ART following bariatric surgery.

Interventions Used to Improve Communication Competencies in Surgical Residencies: A Systematic Review.

OBJECTIVE: To explore which educational interventions have been used to address communication skill in surgical residents. DESIGN: Systematic review. RESULTS: Several interventions have been used to improve communication skill in residency, including simulation, standardized patients, and didactic teaching. These interventions vary widely, yet the majority of interventions tend to result in improvement in resident communication skill. CONCLUSIONS: Communication is an essential skill for surgical trainees to learn. Integration of communication-focused educational interventions can lead to improved skill development in surgical residents.

Why Didn't You Call Me? Factors Junior Learners Consider When Deciding Whether to Call Their Supervisor.

OBJECTIVE: Over half of junior learners (JL) feel pressure to work independently and report rarely calling their supervisor. It is unclear how JL decide whether or not to call their supervisor. The study aims to identify factors that JL consider when responding to clinical scenarios and deciding whether to call senior residents (SR) and compare them to factors identified by SR. METHODS: Fifteen cognitive interviews were conducted with SR and JL. Participants were given 8 to 15 sample pages and probed regarding the factors they considered when triaging the page and deciding whether to inform a SR. De-identified interview transcripts were inductively coded using an interpretative phenomenological analysis (IPA) approach. SETTING: Department of Surgery, Faculty of medicine at the University of Ottawa in Canada. PARTICIPANT: Five general surgery SR and ten JL, which included 5 senior medical students and 5 general surgery junior residents. RESULTS: JL and SR indicated a clear need to call SR when managing high acuity pages, which included hemodynamic instability, decreased level of consciousness, or codes (ie, trauma, cardiac arrest). In the absence of high acuity findings, JL judged whether to call SR based on 10 patient and learner-related factors. Patient-related factors include: 1) time since surgery, 2) patient appearance, 3) patient requires intervention, and 4) lack of improvement after initial independent management attempt. Learner-related factors were categorized into clinical (5-8) and social factors (9-10): 5) nurse's level of concern, 6) familiarity with the patient, 7) gut feeling, 8) prior experience managing this presentation, 9) time of day, and 10) interpersonal dynamic with SR. While SR identified all patient-related and clinical factors, they did not cite the 2 social factors JL considered. CONCLUSION: When pages lack high-acuity findings, JL consider various patient and learner factors when deciding whether to inform SR. Discussing these factors may help guide new JL regarding when they should call their supervisor. Understanding social factors is important to create a culture that minimizes their influence on JL's decision-making and promotes patient safety.

Investigating factors influencing decision-making around use of breastmilk substitutes by health care professionals: a qualitative study.

BACKGROUND: Breastfeeding is recognized as the gold standard of infant feeding and nutrition. The World Health Organization recommends exclusive breastfeeding (EBF) of infants for the first 6 months of life. A variety of factors may impact breastfeeding practices in-hospital which may continue after hospital discharge, such as the use of breastmilk substitutes (BMS). The Baby-Friendly Initiative (BFI), which aims to promote and support breastfeeding practices, established a target rate of 75% for EBF from birth to hospital discharge. Currently, this target is not being met at The Ottawa Hospital (TOH), indicating there is room for improvement in EBF rates. The purpose of this study is to explore health care professionals (HCP) decision-making around use of BMS and identify factors that drive the use of BMS with and without medical indications. METHODS: In this qualitative study, semi-structured interviews were conducted with HCPs within TOH from January to June 2022. All participants had experience in maternity or postpartum care and were probed on factors influencing use of BMS at this institution. Interview transcripts were coded using an inductive approach. RESULTS: A total of 18 HCPs were interviewed including physicians, midwives, lactation consultants, and registered nurses. Multilevel barriers influencing the use of BMS were categorized into patient, HCP, and institution-level factors. Subthemes that emerged ranged from parental preferences, training differences amongst HCPs, to budget and staffing issues. Over half of HCPs were prepared to answer questions on EBF and were familiar with the BFI. Although most were supportive of this institution receiving BFI designation, a few providers raised concerns of its impact on parents who would like to supplement. CONCLUSIONS: Several modifiable factors influencing decision-making for use of BMS were identified. These findings will be used to inform unit leads, help identify effective strategies to address modifiable barriers, and develop tailored breastfeeding supports to improve EBF rates.

Assessing the Use of Twitter to Share Canadian Residency Match Information During the COVID-19 Pandemic.

Purpose In their final year, medical students explore prospective residency programs by completing visiting electives and attending interviews during the Canadian Resident Matching Service (CaRMS) process. Due to COVID-19, visiting electives and in-person interviews were suspended, leaving residency programs searching for alternate ways to share CaRMS information with applicants. This study evaluates the utility of Twitter to share CaRMS-related information prior to and during the pandemic. Methods Primary tweets published from three CaRMS cycles between 2018 and 2021 were identified using the analytics tool Vicinitas. The type, content, and language of tweets and the date and location of publication were extracted. Demographic data about tweet creators were determined using provincial regulatory college databases and institutional websites. Descriptive statistics were employed for categorical variables. All tweets were deductively analyzed. Results Of the 1,843 tweets, 603, 472, and 768 were published during the 2018-2019, 2019-2020, and 2020-2021 cycles, respectively. Most tweets were written in English (97.4%) and by medical students (29.5%) affiliated with Ontario universities. The most common types of tweets were supportive messages (29.1%), reflections about CaRMS (24.7%), and positive match results (20.8%). Rurally located institutions experienced the greatest increase in the total number of tweets between the pre- and full-COVID cycles. Conclusion Since COVID-19, Twitter has been increasingly used by medical professionals to share CaRMS-related information, primarily to promote programs and advertise CaRMS events. Given the environmental and financial benefits, CaRMS interviews will likely remain virtual, which highlights the ongoing need for residency programs to use social media platforms to share information with prospective applicants.

Transforming the "SEAD": Evaluation of a Virtual Surgical Exploration and Discovery Program and its Effects on Career Decision-Making.

OBJECTIVE: The abrupt cessation of in-person education due to the COVID-19 pandemic has made it difficult for preclerkship students to explore a career in surgery. To supplement the lack of exposure, the Surgical Exploration and Discovery (SEAD) program was transitioned to an entirely virtual format. This study aims to describe the virtual SEAD program and evaluate its effectiveness as a career decision-making (CDM) intervention. DESIGN: The week-long program was delivered on Microsoft Teams, featured 11 surgical specialties, and comprised four activities: live demonstrations, virtual operating room observerships, career talks, and technical skills workshops. The program was evaluated using the four levels of the Kirkpatrick model: (1) reactions, (2) knowledge, (3) CDM behaviors - assessed using the Career Decision-making Difficulties Questionnaire (CDDQ) - and (4) results. The latter was indirectly assessed using CDDQ scores from an in-person SEAD program, where lower CDDQ scores indicate less difficulty with CDM. SETTING: Faculty of Medicine at the University of Ottawa in Ontario, Canada. PARTICIPANTS: Forty pre-clerkship students (27 first and 13 second year students) at the University of Ottawa RESULTS: Level 1: 97.5% of participants rated the program as good or very good. Live demonstration and technical skills workshops were the highest rated activities. Level 2: participants' scores on knowledge-based questions about a surgical career significantly increased following the program (pre: 9/25 vs post: 15/25, p = 0.008). Level 3: overall mean CDDQ scores (±SD) decreased difficulties with significantly following the program (pre: 45.6 ± 10.5 vs post: 38.8 ± 10.9, p < 0.001), which indicates decreased CDM difficulties. Level 4: Except for one sub-category, the difference in mean CDDQ scores between the virtual and in-person programs were not significantly different. CONCLUSION: The program received the positive reactions and significantly increased participants' knowledge. The change in CDDQ scores following the virtual program suggests it may reduce career decision-making difficulties in the short-term. In-person surgical exposure remains important; however, a hybrid model may be valuable in resource limited settings. WC: 300.

Etiology of stillbirth in a tertiary care center: a retrospective cohort study assessing ultrasound, laboratory, and pathology investigations.

BACKGROUND: Canadian stillbirth data are limited, and a significant proportion of pregnancies resulting in stillbirth have no attributable cause. The objective of this study was to characterize stillbirth case investigations and management at a tertiary care hospital in Ontario, Canada. METHODS: This was a retrospective chart review study of all cases of singleton stillbirth at The Ottawa Hospital between 1 January 2012 and 31 December 2017. Terminations and multiples stillbirths were excluded. Chart reviews were conducted to extract maternal sociodemographic, obstetrical, and fetal characteristics, including results from antenatal ultrasounds, autopsy, placenta pathology, and laboratory investigations. RESULTS: A total of 155 eligible cases of stillbirth were identified, resulting in a 6-year stillbirth rate of 4.2 per 1000 total births. The median maternal age was 31.0 years (IQR: 29.0, 35.0) and the median gestational age at delivery was 28 weeks (IQR: 24, 35). A total of 9 (5.8%) pregnant individuals had a history of previous stillbirth. Of the 155 stillbirths, 35% underwent the full suite of post-loss laboratory, placental, and fetal autopsy investigations. 63.2% of cases had post-loss laboratory investigations completed. 76% and 71% of cases had fetal autopsy and placenta pathology evaluations completed, respectively. Antenatal characteristics associated with stillbirth included fetal anomalies/genetic markers (27.1%), umbilical cord and placental anomalies (24.5%), fetal growth abnormalities (27.7%), cervical/uterine abnormalities (11.6%), and amniotic fluid abnormalities (25.1%). The most common autopsy findings included evidence of infection (22.7%), fetal anomalies (12.6%), and fetal hypoxia (10%). The most common placental pathology findings included features of placental insufficiency (21.8%), retroplacental abnormalities (16.3%), and umbilical cord accident/infarct (15.4%). CONCLUSIONS: Our findings demonstrate that as many as two-thirds of singleton stillbirth cases at our center did not receive the post-perinatal loss investigations recommended by clinical practice guidelines. More thorough collection of post-stillbirth data at all levels (institutional, provincial, national) is warranted to improve our understanding of stillbirth epidemiology, etiology, and management in Canada.

The impact of bariatric surgery on assisted reproductive technology outcomes: a systematic review protocol.

BACKGROUND: Individuals with obesity are at higher risk of experiencing complications during their pregnancy and may also experience infertility, requiring assisted reproductive technologies (ART) to conceive. The current body of literature demonstrates that bariatric surgery decreases an individual's risk of developing a variety of obesity-related obstetrical conditions during and after pregnancy. However, the effects of bariatric surgery on ART outcomes are not well understood. Therefore, the paucity in the literature warrants a need to determine these effects. METHODS: We will search electronic databases, including MEDLINE, Embase, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL), as well as the gray literature and the reference lists of included articles. We will screen all studies published between January 1978 and the present day that explore the impact of bariatric surgery on ART outcomes for women and men. We will include observational studies. Two independent reviewers will assess the studies for inclusion and extract data for each article. The main outcome that will be analyzed is live birth rate. Secondary outcomes such as time to conception, number of rounds of ART, type of bariatric surgery, and length of time between bariatric surgery and initiation of ART will also be recorded. Risk of bias will be conducted using the National Institutes of Health Study Quality Assessment Tools. A random effects model will be used to account for statistical analysis and results will be pooled with forest plots. In the event of statistical and reporting heterogeneity, we will provide a qualitative synthesis and narrative review of the results. DISCUSSION: This review will provide information on the outcomes of ART following bariatric surgery and may help healthcare professionals make informed decisions about the length of time between bariatric surgery and initiation of ART. The study findings may be of interest to various stakeholders including patients, bariatric surgeons, obstetricians, and gynecologists, and those who specialize in obesity medicine and reproductive endocrinology and infertility. We plan to disseminate our findings through presentations, publications, and social media releases to individuals who are navigating infertility and are interested in undergoing or have undergone bariatric surgery, healthcare professionals, policymakers, and researchers.

Trust Me, I Know Them: Assessing Interpersonal Bias in Surgery Residency Interviews.

Background: Residency selection integrates objective and subjective data sources. Interviews help assess characteristics like insight and communication but have the potential for bias. Structured multiple mini-interviews may mitigate some elements of bias; however, a halo effect is described in assessments of medical trainees, and degree of familiarity with applicants may remain a source of bias in interviews. Objective: To investigate the extent of interviewer bias that results from pre-interview knowledge of the applicant by comparing file review and interview scores for known versus unknown applicants. Methods: File review and interview scores of applicants to the University of Ottawa General Surgery Residency Training Program from 2019 to 2021 were gathered retrospectively. Applicants were categorized as "home" if from the institution, "known" if they completed an elective at the institution, or "unknown." The Kruskal-Wallis H test was used to compare median interview scores between groups and Spearman's rank-order correlation (rs) to determine the correlation between file review and interview scores. Results: Over a 3-year period, 169 applicants were interviewed; 62% were unknown, 31% were known, and 6% were home applicants. There was a statistically significant difference (P=.01) between the median interview scores of home, known, and unknown applicants. Comparison of groups demonstrated higher positive correlations between file review and interview scores (rs=0.15 vs 0.36 vs 0.55 in unknown, known, and home applicants) with increasing applicant familiarity. Conclusions: There is an increased positive correlation between file review and interview scores with applicant familiarity. The interview process may carry inherent bias insufficiently mitigated by the current structure.

Assessment of laparoscopic skills: comparing the reliability of global rating and entrustability tools.

Background: Competence by design (CBD) residency programs increasingly depend on tools that provide reliable assessments, require minimal rater training, and measure progression through the CBD milestones. To assess intraoperative skills, global rating scales and entrustability ratings are commonly used but may require extensive training. The Competency Continuum (CC) is a CBD framework that may be used as an assessment tool to assess laparoscopic skills. The study aimed to compare the CC to two other assessment tools: the Global Operative Assessment of Laparoscopic Skills (GOALS) and the Zwisch scale. Methods: Four expert surgeons rated thirty laparoscopic cholecystectomy videos. Two raters used the GOALS scale while the remaining two raters used both the Zwisch scale and CC. Each rater received scale-specific training. Descriptive statistics, inter-rater reliabilities (IRR), and Pearson's correlations were calculated for each scale. Results: Significant positive correlations between GOALS and Zwisch (r = 0.75, p < 0.001), CC and GOALS (r = 0.79, p < 0.001), and CC and Zwisch (r = 0.90, p < 0.001) were found. The CC had an inter-rater reliability of 0.74 whereas the GOALS and Zwisch scales had inter-rater reliabilities of 0.44 and 0.43, respectively. Compared to GOALS and Zwisch scales, the CC had the highest inter-rater reliability and required minimal rater training to achieve reliable scores. Conclusion: The CC may be a reliable tool to assess intraoperative laparoscopic skills and provide trainees with formative feedback relevant to the CBD milestones. Further research should collect further validity evidence for the use of the CC as an independent assessment tool.

Contexte: Les programmes de résidence structurés autour de la compétence par conception (CPC) dépendent de plus en plus d'outils qui fournissent des évaluations fiables, nécessitent une formation minimale des évaluateurs et mesurent la progression dans les étapes de la CPC. Pour évaluer les compétences peropératoires, les échelles d'évaluation globale et de confiance sont couramment utilisées mais peuvent nécessiter une formation approfondie. Le Continuum des compétences (CC) est un cadre de la CPC qui peut être utilisé comme outil d'évaluation des compétences laparoscopiques. L'étude visait à comparer le CC à deux autres outils d'évaluation : l'évaluation globale opératoire des compétences laparoscopiques (GOALS) et l'échelle de Zwisch. Méthodes: Quatre chirurgiens experts ont évalué trente vidéos de cholécystectomie laparoscopique. Deux évaluateurs ont utilisé l'échelle GOALS tandis que les deux autres ont utilisé l'échelle Zwisch et le CC. Chacun d'eux avait reçu une formation spécifique à l'échelle utilisée. Des statistiques descriptives, la fiabilité inter-évaluateurs (FIÉ) et des corrélations de Pearson ont été calculées pour chaque échelle. Résultats: Des corrélations positives significatives ont été trouvées entre les échelles GOALS et Zwisch (r=0.75, p<0.001), CC et GOALS (r=0.79, p<0.001), et CC et Zwisch (r=0.90, p<0.001). Le CC avait une fiabilité inter-évaluateurs de 0,74 tandis que les échelles GOALS et Zwisch avaient des fiabilités inter-évaluateurs de 0,44 et 0,43, respectivement. Par rapport aux échelles GOALS et Zwisch, le CC avait la fiabilité inter-évaluateurs la plus élevée et ne nécessitait qu'une formation minimale des évaluateurs pour obtenir des scores fiables. Conclusion: Le CC constituerait un outil fiable pour évaluer les compétences laparoscopiques peropératoires et pour fournir aux stagiaires une rétroaction formatrice pertinente pour les étapes de la CPC. Des recherches supplémentaires devraient être entreprises pour recueillir plus de preuves de validité pour l'utilisation du CC comme outil d'évaluation indépendant.

Factors impacting antenatal care utilization: a systematic review of 37 fragile and conflict-affected situations.

BACKGROUND: It is estimated that over 930 million people live in fragile and conflict-affected situations (FCAS) worldwide. These regions, characterized by violence, civil unrest, and war, are often governed by corrupt administrations who are unwilling to provide their citizens with basic human rights. Individuals living in FCAS face health inequities; however, women are disproportionally affected and face additional barriers to accessing sexual and reproductive services, including antenatal care (ANC). This systematic review aims to identify the factors that impact ANC usage in the 37 countries or regions classified as FCAS in 2020 by The World Bank. METHODS: Using the PRISMA guidelines, a systematic search of five databases (SCOPUS, Web of Science, PubMed, EMBASE, and CINAHL) was conducted. Results were limited to human studies, written in English, and published between January 2002 and January 2022. Studies that identified factors affecting utilization of ANC or maternal health services were included for review and critically appraised using the National Institute of Health's Quality Assessment Tools. Findings were summarized using a narrative synthesis approach. RESULTS: The database search yielded 26,527 studies. After title, abstract and full-text review, and exclusion of duplicate articles, 121 studies remained. Twenty-eight of the 37 FCAS were represented in the included studies. The studies highlighted that women in FCAS' are still not meeting the World Health Organization's 2002 recommendation of four ANC visits during pregnancy, a recommendation which has since been increased to eight visits. The most cited factors impacting ANC were socioeconomic status, education, and poor quality of ANC. Despite all studies being conducted in conflict-affected regions, only nine studies explicitly identified conflict as a direct barrier to accessing ANC. CONCLUSION: This review demonstrated that there is a paucity in the literature examining the direct and indirect impacts of conflict on ANC utilization. Specifically, research should be conducted in the nine FCAS that are not currently represented in the literature. To mitigate the barriers that prevent utilization of maternal health services identified in this review, policy makers, women utilizing ANC, and global organizations should attempt to collaborate to enact policy change at the local level.

Evaluation of a breastmilk hand expression toolkit: the M.I.L.K survey study.

BACKGROUND: Breastmilk hand expression (BMHE) is recommended to promote lactation, relieve breast engorgement, and collect milk for future infant feedings. Resources to teach this skill are limited and infrequently developed in partnership with the obstetrical population. In collaboration with maternity care experts and individuals with recent breastfeeding experience, we designed a one-page toolkit that describes the process of BMHE and includes step-by-step instructions and images to illustrate the technique. This study aimed to evaluate the readability, clarity of content, layout, and informational value of this BMHE toolkit. METHODS: Individuals who intended to breastfeed, were currently breastfeeding, or had recently breastfed were electronically surveyed and completed a two-part survey that consisted of radio, multi-select, Likert scale, and open-ended questions. Part one captured sociodemographic factors, obstetrical history, and breastfeeding practices. Part two collected feedback on the BMHE toolkit. Participants were recruited electronically through social media and posters were circulated in antenatal and postnatal care settings in Ottawa, Canada between November 2020 and February 2021. RESULTS: Of the 123 participants, 117 (95.1%) had heard of hand expression prior to reviewing the toolkit and 99 (80.5%) had hand expressed before. Among the 48 participants who were no longer exclusively breastfeeding at the time of the survey, 22 (45.8%) had exclusively breastfed their infant for at least six months and 7 (14.6%) had discontinued exclusive breastfeeding within the first month. When asked about the BMHE toolkit, 118 (95.9%) participants said it was informative, 115 (93.5%) said it was easy to understand, and 114 (92.7%) said it was well laid-out. When asked about information seeking behaviours, participants indicated a preference for online resources (58.5%) and video resources (22.0%). CONCLUSIONS: The BMHE toolkit was well received by participants and the feedback was favourable overall. The survey feedback will be used to create a revised version of the toolkit that has been validated by the obstetrical patient population. Future research should focus on identifying implementation strategies to optimize the use of the toolkit and increase its effectiveness as an educational resource to teach participants correctly BMHE.

Prevalence of SARS-CoV-2 infection among obstetric patients in Ottawa, Canada: a descriptive study.

BACKGROUND: There is limited information on the prevalence of SARS-CoV-2 infection in obstetric settings in Canada, beyond the first wave of the COVID-19 pandemic (February to June 2020). We sought to describe the prevalence of SARS-CoV-2 infection in pregnant people admitted to triage units at a tertiary care hospital in Ottawa, Canada. METHODS: We conducted a descriptive study of pregnant people admitted to obstetric triage assessment units at The Ottawa Hospital between Oct. 19 and Nov. 27, 2020 (second local wave of the COVID-19 pandemic). Participants underwent SARS-CoV-2 polymerase chain reaction (PCR) (via naso- or oropharyngeal swabs) and serology testing upon admission. We excluded individuals younger than 18 years, those who did not speak English or French, those who enrolled in conflicting studies, those admitted for pregnancy termination and those triaged between 11:31 pm and 7:29 am. Swab and serology samples were analyzed using digital droplet PCR and enzyme-linked immunosorbent assays, respectively. We defined SARS-CoV-2 seropositivity as a positive result for immunoglobulin (Ig) G, either alone or in combination with IgM or IgA. RESULTS: Of the 632 eligible patients, 363 (57.4%) consented to participation and 362 collectively provided 284 swab and 352 blood samples eligible for analysis. Common reasons for declining participation included feeling overwhelmed or anxious, being worried about repercussions of testing, pain or discomfort with testing or disinterest in research. Participants were mostly multiparous (53.9%) and in their third trimester upon admission (88.4%). In all, 18 (4.9%) participants had evidence of SARS-CoV-2 exposure; 2 (0.7%) of 284 were positive for SARS-CoV-2 by PCR and 16 (4.5%) of 352 were positive for IgG antibodies to SARS-CoV-2. INTERPRETATION: During the second local wave of the COVID-19 pandemic, the prevalence of active SARS-CoV-2 infection among obstetric patients in Ottawa was 0.7% and seroprevalence was 4.5%. Our low participation rate highlights the need for improvements in patient education and public health messaging on the benefits of SARS-CoV-2 testing programs.
