Implementation of Multiple Marker Screening for Preterm Preeclampsia in a Single Tertiary Obstetric Centre.

OBJECTIVES: Early assessment of pregnant individuals for risk of preterm preeclampsia (PE) is possible at the 11-14 week ultrasound visit using a validated multiple marker algorithm, allowing timely use of preventative low-dose acetylsalicylic acid (LDA) in high-risk patients. With no established early screening program for preterm PE in Canada, our objectives were to assess the acceptability and operational impact of routine screening for preterm PE during the 11-14 week ultrasound visit, evaluate uptake and adherence to LDA when recommended, and assess screening performance. METHODS: A prospective implementation study of preterm PE screening among pregnant patients at the ultrasound unit of a tertiary obstetric centre in Toronto, Canada. RESULTS: A total of 1057 patients were screened, with an acceptance rate of 87.1%. First-trimester ultrasound appointment time increased by a median time of 7 minutes (Interquartile range 6-9). By 16 weeks gestation, 88.7% of high-risk patients had started LDA, with adherence of 88.7%‒94.6% from 16‒36 weeks. Satisfaction with counselling was ≥7/10 in more than 95% of patients. There were 7 cases of preterm PE (0.73%), 3 in the low-risk group (0.35%), and 4 in the high-risk group (4.1%). When accounting for LDA use, the treatment-adjusted detection rate was 78.6%. CONCLUSIONS: We demonstrate successful implementation of a validated, effective screening and prevention program for preterm PE as a first step in the implementation of a broader program adaptable for cultural, access/equity considerations, and marker availability.

Surgeon Gender and Performance Outcomes for Hysterectomies: Retrospective Cohort Study.

STUDY OBJECTIVE: To evaluate whether there are differences in several performance metrics between male and female surgeons for hysterectomies. DESIGN: Multicenter retrospective cohort study. We matched surgeries performed by female surgeons to those by male surgeons using a propensity score and compared outcomes by gender after adjusting for years in practice and fellowship training. SETTING: A total of 6 hospitals (3 academic, 3 community) in Ontario, Canada, between July 2016 and December 2019. PATIENTS: All consecutive patients. INTERVENTIONS: Hysterectomy. MEASUREMENTS AND MAIN RESULTS: Primary outcome was a composite of any complication or return to emergency room (ER) within 30 days. Secondary outcomes were grade II or greater complications, return to ER, and operative time. We included 2664 hysterectomies performed by 77 surgeons. After propensity matching, 963 surgeries performed by females were compared with 963 performed by males. There were no differences in the primary (relative risk [RR], 0.92; 95% confidence interval [CI], 0.71-1.20; p = .56) or secondary outcomes of grade II or greater complication (RR, 1.01; 95% CI, 0.71-1.45; p = .96) or return to ER (RR, 0.81; 95% CI, 0.55-1.20; p = .30). However, surgeries performed by males were 24.72 minutes shorter (95% CI, 18.09-31.34 minutes; p <.001). Entire cohort post hoc regression analysis confirmed these findings. E-value analysis indicated that it is unlikely for an unmeasured confounder to undo the observed difference. CONCLUSION: Although complication and readmission rates are similar, male surgeons may have a shorter operating time than female surgeons for hysterectomies, which may have implications for health systems and inequalities in surgeon renumeration.

Consent Practices for Assisted Vaginal Births (AVB) at Two Tertiary Care Hospitals: A Retrospective Review of Physician Documentation.

OBJECTIVE: To determine whether assisted vaginal birth (AVB) consent documentation, a surrogate for in vivo consent, aligns with Canadian practice guidelines at 2 Canadian tertiary-level obstetric centres. METHODS: This was a retrospective review of AVBs (vacuum and forceps) from July 2019 to December 2019 at 2 tertiary-level hospitals with template-based (Site 1) or dictation-based (Site 2) documentation. We extracted, from obstetric and neonatal charts, AVB type, physician and documenter types (resident/fellow/family doctor/generalist obstetrics and gynecology [OBGYN]/maternal-fetal medicine), and consent elements (present/absent) based on a predetermined checklist. Data were summarized and comparisons were made using chi-square test, Fisher exact test, and logistic regression, where appropriate. RESULTS: We identified 551 AVBs (156 forceps, 395 vacuum) with most documentation completed by generalist OBGYNs or residents (333/551, 60.5%). Most vacuum-assisted deliveries documented no specific maternal (366/395, 92.7%) or neonatal (364/395, 92.2%) risks, and 107/156 (68.6%) and 106/156 (67.9%) forceps-assisted deliveries lacked specific documentation of maternal and neonatal risk, respectively. At Site 2, postpartum hemorrhage risk at vacuum-assisted deliveries was more commonly documented (6/90 [6.7%] vs. 2/395 [0.7%], P = 0.002) as was at least 1 neonatal risk and risk of obstetrical anal sphincter injury at forceps-assisted deliveries (50/133 [37.6%] vs. 0/23 [0%], P < 0.001) and (43/133 [32.3%] vs. 0/23 [0%], P = 0.001), respectively. CONCLUSIONS: Opportunity to improve AVB consent documentation exists, warranting quality improvement initiatives.

Health Care Practitioners' Attitudes and Knowledge Regarding Trial of Labour After Cesarean Delivery (TOLAC): A Survey of Canadian Obstetrical Care Providers.

OBJECTIVES: To understand current attitudes and practice patterns of obstetrical care providers regarding trial of labour after cesarean (TOLAC) and to assess misconceptions regarding eligibility for and risks associated with TOLAC. METHODS: A survey was developed based on published literature, validated by a statistician, and piloted with Canadian obstetricians. French and English versions were distributed via the mailing list of the Society of Obstetricians and Gynaecologists of Canada and social media. Practising obstetrical care providers with an office antenatal practice were eligible to participate. Data were analyzed using descriptive statistics and correlational and multiple regression analyses. RESULTS: A total of 381 people responded, with representation from every Canadian province and territory. Obstetrician-gynaecologists (239, 63%), family physicians (100, 26%), and midwives (42, 11%) responded. Most participants (277, 78%) thought that TOLAC should be actively encouraged. Only 141 (40%) used a decision aid when counselling patients, although most respondents (250, 71%) thought it would be useful. Providers were less comfortable offering oxytocin induction compared with cervical foley or amniotomy (P < 0.001) and offering TOLAC to patients with an unknown uterine scar (P < 0.001). Providers in western Canada reported more comfort offering TOLAC to patients with more than 1 previous cesarean delivery compared with other regions. Two hundred nine participants (62%) reported that they had had at least 1 patient with a uterine rupture, with the minority of cases (13, 6%) resulting in litigation. CONCLUSIONS: This study offers new information on current national practice patterns and provider attitudes regarding TOLAC. These results can be used to guide future educational initiatives to increase TOLAC rates.

Guideline No. 423: Female Genital Cosmetic Surgery and Procedures.

OBJECTIVE: To provide Canadian surgeons and other providers who offer female genital cosmetic surgery (FGCS) and procedures, and their referring practitioners, with evidence-based direction in response to increasing requests for, and availability of, vaginal and vulvar surgeries and procedures that fall outside the traditional realm of medically indicated reconstructions. TARGET POPULATION: Women of all ages seeking FGCS or procedures. BENEFITS, HARMS, AND COSTS: Health care providers play an important role in educating women about their anatomy and helping them appreciate individual variations. Most women requesting FGCS and procedures have normal genitalia, and up to 87% are reassured by counselling. At this time, due to lack of rigorous clinical or scientific evidence of short- and long-term efficacy and safety, FGCS and procedures for non-medical indications cannot be supported. FGCS and procedures are typically provided in the private sector, where costs are borne by the patient. EVIDENCE: Literature was retrieved through searches of MEDLINE, Scopus, and The Cochrane Library using appropriate controlled vocabulary and keywords. The selected search terms represented keywords for FGCS (labiaplasty, surgery, vaginal laser therapy, laser vaginal tightening, vaginal laser, vaginal rejuvenation, vaginal relaxation syndrome, hymenoplasty, vaginal cosmetic procedures) combined with female genital counselling, consent, satisfaction, follow-up, adolescent, and body dysmorphic or body dysmorphia. The search was restricted to publications after 2012 in order to update the literature since the previous guideline on this topic. Results were restricted to systematic reviews, randomized controlled trials, and observational studies. Studies were restricted to those involving humans, and no language restrictions were applied. The search was completed on May 20, 2020, and updated on November 10, 2020. VALIDATION METHODS: The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See online Appendix A (Tables A1 for definitions and A2 for interpretations of strong and weak recommendations). INTENDED AUDIENCE: Gynaecologists, primary care providers, surgeons performing FGCS and/or procedures.

Directive clinique no 423 : Interventions chirurgicales et thérapeutiques esthétiques génitales féminines.

OBJECTIF: Fournir aux chirurgiens et autres fournisseurs de soins canadiens qui réalisent des interventions chirurgicales ou thérapeutiques esthétiques génitales féminines, et tout praticien demandeur, des directives fondées sur des données probantes en réponse à l'augmentation des demandes et de la disponibilité des interventions chirurgicales et thérapeutiques vaginales et vulvaires sortant du cadre traditionnel de la reconstruction avec indication médicale. POPULATION CIBLE: Les femmes de tous âges qui consultent pour subir une intervention chirurgicale ou thérapeutique esthétique génitale. BéNéFICES, RISQUES ET COûTS: Les professionnels de la santé qui prodiguent des soins aux femmes jouent un rôle important en renseignant les femmes sur leur anatomie et en les aidant à prendre conscience des variations individuelles. La plupart des femmes qui demandent une intervention chirurgicale ou thérapeutique esthétique génitale féminine ont des organes génitaux normaux, et jusqu'à 87 % d'entre elles sont rassurées par des conseils. À l'heure actuelle, étant donné le manque de données probantes cliniques et scientifiques rigoureuses sur l'efficacité et l'innocuité à court et à long terme, il n'y a aucune base pour se prononcer en faveur des interventions chirurgicales ou thérapeutiques esthétiques génitales féminines sans indication médicale. Les interventions chirurgicales ou thérapeutiques esthétiques génitales féminines sont généralement réalisées dans le secteur privé, où les coûts sont assumés par la patiente. DONNéES PROBANTES: La littérature publiée a été rassemblée par des recherches dans les bases de données Medline, Scopus et Cochrane Library au moyen de termes et mots clés pertinents et validés. Les termes de recherche sélectionnés se composaient de mots clés sur les interventions chirurgicales ou thérapeutiques esthétiques génitales féminines (labiaplasty, surgery, vaginal laser therapy, laser vaginal tightening, vaginal laser, vaginal rejuvenation, vaginal relaxation syndrome, hymenoplasty, vaginal cosmetic procedures) combinés à female genital counselling, consent, satisfaction, follow-up, adolescent et body dysmorphic or body dysmorphia. La recherche a été limitée aux articles publiés après 2012 afin de mettre à jour la documentation depuis la dernière directive à ce sujet. Les résultats ont été restreints aux revues systématiques, aux essais cliniques randomisés et aux études observationnelles. Les études ont été limitées à celles menées chez l'humain seulement, et aucune restriction linguistique n'a été appliquée. La recherche a été effectuée le 20 mai 2020 et mise à jour le 10 novembre 2020. MéTHODES DE VALIDATION: Les auteures ont évalué la qualité des données probantes et la force des recommandations en utilisant le cadre méthodologique d'évaluation, de développement et d'évaluation (GRADE). Voir l'annexe A en ligne (tableau A1 pour les définitions et tableau A2 pour l'interprétation des recommandations fortes et faibles). PROFESSIONNELS CONCERNéS: Gynécologues, fournisseurs de soins primaires, chirurgiens réalisant des interventions chirurgicales et/ou thérapeutiques esthétiques génitales féminines. RECOMMANDATIONS.

Impact of Minimally Invasive Gynaecology Fellowship Training on Quality Performance Metrics for Hysterectomy.

OBJECTIVE: To evaluate differences in quality metrics between hysterectomies performed by fellowship-trained surgeons and those performed by generalists. METHODS: Retrospective review of 2845 consecutive hysterectomies by 75 surgeons (23 fellowship-trained, 52 generalists) at 7 hospitals in Ontario, Canada. The primary outcome was a composite of any complication or return to the emergency department (ED) within 30 days of hysterectomy. Secondary outcomes were 2 quality outcome measures (grade of complication and return to ED within 30 days) and 4 quality process measures (minimally invasive hysterectomy rate, rate of preoperative anemia, same-day discharge for laparoscopic hysterectomy [LH], and performing cystoscopy at LH). RESULTS: Fellowship-trained surgeons were more likely to perform concurrent resection of endometriosis, bilateral ureterolysis, lysis of adhesions, uterine/internal iliac artery ligation, and morcellation (all P < 0.001). Generalists performed more vaginal procedures, including vaginal repair, vault suspension, and insertion of mid-urethral sling (all P < 0.001). After controlling for patient and surgical factors, there was no difference in the primary outcome (adjusted odds ratio [aOR] 1.07; 95% CI 0.79-1.45, P = 0.667). Fellowship-trained surgeons were more likely to perform minimally invasive hysterectomy (aOR 2.38; 95% CI 1.15-4.93, P = 0.020), had higher rates of same-day discharge for LH (aOR 2.23; 95% CI 1.31-3.81, P = 0.003), and were more likely to perform cystoscopy (unadjusted OR 2.94; 95% CI 2.30-3.85, P < 0.001). There were no differences in the rates of preoperative anemia, surgical complications, and ED visits. CONCLUSION: Differences exist between fellowship-trained surgeons and generalists regarding case mix and process quality metrics. Postoperative complications and readmissions were comparable for both groups of surgeons.

Decreasing Cesarean Delivery Rates Using a Trial of Labour After Cesarean (TOLAC) Bundle.

OBJECTIVE: To develop and implement a trial of labour after cesarean delivery (TOLAC) bundle-a group of interventions aimed at decreasing cesarean delivery (CD) for women who have had a prior CD (Robson group 5). METHODS: A TOLAC bundle was developed that included: (1) educational rounds for health care providers, (2) a physician-patient TOLAC discussion aid, and (3) patient-centred educational resources. A before-and-after study design was employed. A one-year chart review determined baseline CD rates in Robson group 5 patients at a tertiary care academic centre. Following this, from February 1, 2018 until May 31, 2019, each bundle intervention was sequentially introduced every four to six months and modified based on provider feedback. Obstetricians were provided with their individual CD rates using an audit-and-feedback approach prior to the introduction of the next intervention. RESULTS: The baseline CD rate for Robson group 5 patients was 71% (175/247 eligible patients). Following the introduction of the bundle, the CD rate decreased to 61% (131/214 eligible patients). This was a 10% decrease in the CD rate (P = 0.029). A significant increase in rate of induction was noted, from 5% pre-intervention to 11% post-intervention (p = 0.017). There were no significant decreases in the rate of vaginal birth after CD or increases in the rates of uterine rupture or NICU admission. CONCLUSIONS: A TOLAC bundle, consisting of provider education, a TOLAC discussion aid, and patient resources, combined with audit and feedback, decreased CD for Robson group 5 patients.

Perceptions of a night float system of resident call within an obstetrics and gynaecology residency training program.

OBJECTIVE: To determine the attitudes of residents, attending obstetricians, and nursing staff members towards night float resident call, compared with a traditional 24-hour call system. METHODS: In June 2012, obstetrics and gynaecology residents at the University of Toronto who had participated in both a night float and a 24-hour call system were asked to complete an electronic survey. Attending obstetricians and nurses in the labour and delivery unit at two tertiary care hospitals with a night float system of resident call completed electronic and paper surveys, respectively. Questions asked respondents to compare the two systems of call with respect to resident morale, fatigue, and continuity of care, and to indicate which system of call they preferred. RESULTS: Surveys were completed by 20/24 residents (83%), 24/39 attending obstetricians (62%) and 47/58 nurses (81%). Most residents reported less fatigue (17/20, 85%) and improved continuity of care (15/20, 75%) while doing night float call, but morale was mixed. Overall, 14/20 (70%) residents preferred the night float system. Staff perceptions of resident night float call were mixed in all areas, and most reported no difference in resident morale (17/24, 71%). Nurses found residents were less fatigued (32/47, 68%) and easier to work with (34/47, 72%), and felt that night float call improved continuity of care (37/47, 79%). CONCLUSION: Resident attitudes towards night float call are mostly positive. Attitudes of attending obstetricians are mixed, but nurses prefer this system of resident call.

Objectif : Déterminer les attitudes des résidents, des obstétriciens traitants et du personnel infirmier envers la mise en œuvre d'un système d'équipes de garde de nuit (night float) pour les résidents, par comparaison avec un système traditionnel de garde de 24 heures. Méthodes : En juin 2012, nous avons demandé à des résidents en obstétrique-gynécologie de l'Université de Toronto qui avaient participé tant à un système d'équipes de garde de nuit qu'à un système de garde de 24 heures de remplir un questionnaire électronique. Les obstétriciens traitants et le personnel infirmier de la salle de travail et d'accouchement de deux hôpitaux de soins tertiaires comptant un système d'équipes de garde de nuit en ce qui concerne les résidents ont rempli des questionnaires électroniques et en version papier, respectivement. Ces questionnaires demandaient aux répondants de comparer les deux systèmes de garde en ce qui a trait au moral des résidents, à leur fatigue et à la continuité des soins offerts, et d'indiquer lequel de ces deux systèmes ils préféraient. Résultats : Des questionnaires ont été remplis par 20/24 résidents (83 %), 24/39 obstétriciens traitants (62 %) et 47/58 infirmières (81 %). La plupart des résidents ont signalé une fatigue moindre (17/20, 85 %) et une amélioration de la continuité des soins (15/20, 75 %) dans le cadre du système d'équipes de garde de nuit; toutefois, les réponses quant au moral ont été mixtes. De façon globale, 14/20 (70 %) résidents ont préféré le système d'équipes de garde de nuit. Les perceptions du personnel quant à ce dernier ont été mixtes dans tous les domaines; de plus, la plupart des membres du personnel n'ont signalé aucune différence en ce qui concerne le moral des résidents (17/24, 71 %). Les infirmières ont estimé que les résidents étaient moins fatigués (32/47, 68 %) et qu'il était plus facile de travailler avec eux (34/47, 72 %); elles ont de plus estimé que le système d'équipes de garde de nuit améliorait la continuité des soins (37/47, 79 %). Conclusion : Les attitudes des résidents envers le système d'équipes de garde de nuit sont, dans la plupart des cas, positives. Bien que les attitudes des obstétriciens traitants aient été mixtes, les infirmières ont préféré ce système de garde pour ce qui est des résidents.

Female genital cosmetic surgery.

OBJECTIVE: To provide Canadian gynaecologists with evidence-based direction for female genital cosmetic surgery in response to increasing requests for, and availability of, vaginal and vulvar surgeries that fall well outside the traditional realm of medically-indicated reconstructions. EVIDENCE: Published literature was retrieved through searches of PubMed or MEDLINE, CINAHL, and The Cochrane Library in 2011 and 2012 using appropriate controlled vocabulary and key words (female genital cosmetic surgery). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. There were no date or language restrictions. Searches were updated on a regular basis and incorporated in the guideline to May 2012. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. VALUES: The quality of evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table). Recommendations 1. The obstetrician and gynaecologist should play an important role in helping women to understand their anatomy and to respect individual variations. (III-A) 2. For women who present with requests for vaginal cosmetic procedures, a complete medical, sexual, and gynaecologic history should be obtained and the absence of any major sexual or psychological dysfunction should be ascertained. Any possibility of coercion or exploitation should be ruled out. (III-B) 3. Counselling should be a priority for women requesting female genital cosmetic surgery. Topics should include normal variation and physiological changes over the lifespan, as well as the possibility of unintended consequences of cosmetic surgery to the genital area. The lack of evidence regarding outcomes and the lack of data on the impact of subsequent changes during pregnancy or menopause should also be discussed and considered part of the informed consent process. (III-L) 4. There is little evidence to support any of the female genital cosmetic surgeries in terms of improvement to sexual satisfaction or self-image. Physicians choosing to proceed with these cosmetic procedures should not promote these surgeries for the enhancement of sexual function and advertising of female genital cosmetic surgical procedures should be avoided (III-L) 5. Physicians who see adolescents requesting female genital cosmetic surgery require additional expertise in counselling adolescents. Such procedures should not be offered until complete maturity including genital maturity, and parental consent is not required at that time. (III-L) 6. Non-medical terms, including but not restricted to vaginal rejuvenation, clitoral resurfacing, and G-spot enhancement, should be recognized as marketing terms only, with no medical origin; therefore they cannot be scientifically evaluated. (III-L).

Objectif : Fournir aux gynécologues canadiens des directives factuelles en matière de chirurgie esthétique génitale chez la femme, en réponse au nombre grandissant de demandes (et d'interventions) de chirurgie vaginale et vulvaire se situant bien au-delà des reconstructions traditionnellement indiquées sur le plan médical. Résultats : La littérature publiée a été récupérée par l'intermédiaire de recherches menées dans PubMed ou MEDLINE, CINAHL et The Cochrane Library en 2011 et en 2012 au moyen d'un vocabulaire contrôlé et de mots clés appropriés (« female genital cosmetic surgery ¼). Les résultats ont été restreints aux analyses systématiques, aux essais comparatifs randomisés / essais cliniques comparatifs et aux études observationnelles. Aucune restriction n'a été appliquée en matière de date ou de langue. Les recherches ont été mises à jour de façon régulière et intégrées à la directive clinique jusqu'en mai 2012. La littérature grise (non publiée) a été identifiée par l'intermédiaire de recherches menées dans les sites Web d'organismes s'intéressant à l'évaluation des technologies dans le domaine de la santé et d'organismes connexes, dans des collections de directives cliniques, dans des registres d'essais cliniques et auprès de sociétés de spécialité médicale nationales et internationales. Valeurs : La qualité des résultats est évaluée au moyen des critères décrits dans le rapport du Groupe d'étude canadien sur les soins de santé préventifs (Tableau). Recommandations 1. Un des rôles importants des obstétriciens-gynécologues devrait consister à aider les femmes à comprendre leur anatomie et à en respecter les variantes qui leur sont propres. (III-A) 2. Lorsqu'une femme demande la tenue d'interventions esthétiques vaginales, une anamnèse médicale, sexuelle et gynécologique exhaustive devrait être obtenue et l'absence de tout dysfonctionnement sexuel ou psychologique majeur devrait être établie. La présence possible de coercition ou d'exploitation devrait également être écartée. (III-B) 3. Le counseling devrait constituer une priorité dans le cas des femmes qui demandent la tenue d'une chirurgie esthétique génitale. Les sujets abordés dans le cadre du counseling devraient comprendre les variations normales et les modifications physiologiques qui se manifestent au cours de la vie, ainsi que la possibilité de connaître des conséquences imprévues à la suite de la tenue d'une chirurgie esthétique visant les organes génitaux. Le manque de données en ce qui concerne les issues de la chirurgie et les effets des modifications subséquentes attribuables à la grossesse ou à la ménopause devrait également faire l'objet de discussions et être considéré comme faisant partie du processus de consentement éclairé. (III-L) 4. Peu de données soutiennent l'amélioration de la satisfaction sexuelle ou de l'image de soi qui serait attribuable aux interventions de chirurgie esthétique génitale chez la femme. Les médecins qui choisissent de procéder à de telles interventions esthétiques ne devraient pas en faire la promotion à des fins d'amélioration de la fonction sexuelle; de surcroît, le recours à la publicité pour promouvoir les interventions de chirurgie esthétique génitale chez la femme devrait être évité. (III-L) 5. Les médecins qui reçoivent des demandes de chirurgie esthétique génitale de la part d'adolescentes doivent chercher à obtenir des compétences additionnelles en ce qui a trait à l'offre de services de counseling aux adolescentes. De telles interventions chirurgicales ne devraient pas être offertes avant l'atteinte de la pleine maturité physiologique (y compris la maturité génitale); le consentement parental n'est alors pas requis. (III-L) 6. Les termes non médicaux (y compris, entre autres, le rajeunissement vaginal, le resurfaçage clitoridien et l'augmentation du point G) devraient être reconnus comme n'étant que des termes de marketing, sans aucune origine médicale; ainsi, ils ne peuvent faire l'objet d'une évaluation scientifique. (III-L).

Assessing the impact of obesity on surgical quality outcomes among patients undergoing hysterectomy for benign, non-urgent indications.

OBJECTIVE: To evaluate the impact of body mass index (BMI) on surgical quality metrics for patients undergoing benign, non-urgent hysterectomy. STUDY DESIGN: A multicentre, retrospective review at 7 hospitals in Ontario, Canada (4 academic, 3 community) was conducted. Patients undergoing hysterectomy from July 2016 to June 2019 were included. Hysterectomies for premalignant, malignant and emergency indications were excluded. The primary outcome was a composite of any complication or readmission. Secondary outcomes were grade 2 or greater complication, postoperative emergency department (ED) visit, hospital readmission, operative time (ORT) and estimated blood loss (EBL). Patient characteristics (age, ASA class, preoperative diagnoses, preoperative anemia, prior surgeries), surgical factors (endometriosis, adhesions, hysterectomy route, uterine weight, concomitant procedures, ORT, EBL) and surgeon characteristics (volume, fellowship/generalist training, academic/community hospital) were recorded along with complications, hospital readmissions and ED visits. Outcomes were evaluated using logistic regression and log-regression linear analysis grouping patients by BMI category (normal, overweight, obesity class 1, 2, and 3) and by hysterectomy route (abdominal, laparoscopic, and vaginal). RESULTS: 2528 hysterectomies were performed by 67 surgeons. 828 (33%) patients had a normal BMI, 889 (35%) were overweight. 500 (20%) patients had a BMI corresponding to obesity class 1, 205 (8%) class 2 and 106 (4%) class 3. Obese patients had higher ASA class (p <.001) and more prior surgeries (p <.001) compared to patients with normal BMI. Those with class 2 and 3 obesity were younger (p <.001), had greater uterine weight (p <.001) and more intra-operative adhesions (p <.001). After controlling for covariates, there were no differences in the odds of the primary or secondary outcomes, with the exception of patients with class 2 obesity who underwent vaginal hysterectomy. They had 9.1% (11 min) significantly longer ORT (0.091, 95% CI 0.002-0.18, p <.05) and patients with an overweight BMI who underwent vaginal hysterectomy had 28 ml significantly less EBL (-0.154, 95% CI -0.26 to -0.05, p <.01) compared to patients with normal BMI. CONCLUSION: BMI was not independently associated with surgical quality outcomes in patients undergoing hysterectomy for benign, non-urgent indications. Abdominal, laparoscopic, and vaginal hysterectomy can be performed safely in overweight and obese patients.

Avoidable bilateral salpingo-oophorectomy at hysterectomy: a large retrospective study.

OBJECTIVES: Evaluate the proportion of justified bilateral salpingo-oophorectomy (BSO) at hysterectomy, based on pathologic diagnosis, and determine prevalence of avoidable BSO based on pre- and intraoperative considerations and pathologic diagnosis. METHODS: Retrospective review of hysterectomies at seven Ontario, Canada hospitals from 2016 to 2019. Surgeries completed by oncologists or for invasive placentation were excluded. Patient, case, and surgeon characteristics were recorded along with pathologic diagnoses. Avoidable BSO criteria were: preoperative diagnosis of cervical dysplasia or benign diagnosis other than endometriosis, gender dysphoria, risk reduction or premenstrual dysphoric disorder; age < 51 years; absence of intraoperative endometriosis and adhesions; unjustified pathology (where "justified" pathology was endometriosis or (pre)malignant diagnosis except for cervical dysplasia). Patients with avoidable BSO were compared to those having at least one criterion for BSO. Binary logistic regression identified factors most strongly associated with avoidable BSO. RESULTS: Four thousand one hundred ninety-one hysterectomies were completed with 1,422 (33.9%) patients having concomitant BSO. Pathologic diagnosis justified BSO in most patients (1,035/1,422, 72.8%) with endometrial cancer being most common (439/1,422, 30.9%). When preoperative characteristics, intraoperative findings, and pathologic diagnoses were considered, 79 of 1,422 (5.6%) BSOs were avoidable. Compared to cases with at least one criterion for BSO, avoidable BSOs were more frequently completed by generalists (OR 1.80, 95% CI 1.10-2.99, P  = 0.021), for preoperative diagnoses of abnormal uterine bleeding/menorrhagia (OR 3.82, 95% CI 2.35-6.30, P  = 0.001) and fibroids (OR 4.25, 95% CI 2.63-6.92, P  < 0.001). CONCLUSION: Pathologic diagnosis justified most BSOs at hysterectomy. BSO was avoidable in 5.6% of patients, underscoring the need to standardize practice of BSO.

Unnecessary bilateral salpingo-oophorectomy at the time of hysterectomy and potential for ovarian preservation.

OBJECTIVE: To evaluate predictors of bilateral salpingo-oophorectomy at hysterectomy and determine rate of unnecessary bilateral salpingo-oophorectomy. METHODS: Retrospective review of hysterectomies at six Ontario, Canada hospitals from July 2016 to June 2018. Data was extracted from health records coding and electronic medical records. Of patients with concurrent bilateral salpingo-oophorectomy, age, preoperative diagnoses, surgical factors (presence of endometriosis/adhesions), and surgeon training (fellowship/no fellowship) were recorded. Chi-square tests compared indicated and nonindicated bilateral salpingo-oophorectomy cases based on preoperative diagnosis. Criteria for unnecessary bilateral salpingo-oophorectomy were: age under 51 years, benign preoperative diagnosis, and absence of intraoperative endometriosis and adhesions. RESULTS: Concurrent bilateral salpingo-oophorectomy occurred in 749/2,656 (28%) cases with 509/749 (68%) indicated based on preoperative diagnosis. There was interhospital variation in rate of indicated bilateral salpingo-oophorectomy based on preoperative diagnosis (45.3%-76.9%, χ2P < 0.001). Concurrent bilateral salpingo-oophorectomy at academic centers was more likely to have preoperative indications versus those at community hospitals (70% vs 63%, OR 1.42, 95% CI 1.02-1.97, P = 0.04). BSO performed by fellowship-trained surgeons were more likely to be indicated than those performed by generalists (75% vs 63%, OR 1.76, 95% CI 1.26-2.44, P = 0.001). Of patients without preoperative indications for bilateral salpingo-oophorectomy, 105/239 (44%) were under 51 years of age, of which 59 (58%) had no intraoperative endometriosis/adhesions. Ovarian preservation may have been reasonable in 8% (59/749). CONCLUSIONS: Concurrent bilateral salpingo-oophorectomy performed by generalists and at community hospitals was less likely to have preoperative indications. Ovarian preservation was potentially possible for 8%.

A rare etiology of delayed postpartum hemorrhage.

BACKGROUND: Postpartum hemorrhage, immediate or delayed, is a leading cause of maternal death. The most common etiologies are retained products of conception, infection, and subinvolution of the placental implantation site. CASE: A 31-year-old woman, gravida 1, para 0, had an uneventful pregnancy after infertility treatment. She was delivered by intrapartum Caesarean section because of arrest of descent. Twelve days after delivery she had profuse, intermittent vaginal bleeding, but physical examination and pelvic ultrasound failed to reveal the cause. Angiography was performed and showed a left uterine artery pseudoaneurysm that was successfully treated with arterial embolization. CONCLUSION: Use of uterine angiography and embolization at an early stage in the search for the etiology of postpartum hemorrhage helps to decrease morbidity and mortality.
