Objectives: This study assessed same-day availability, dispensing practices, and information provision for mifepristone in Alberta pharmacies.

Study Design: Cross-sectional data from 1620 pharmacies (>99% response) were collected from pharmacy respondents using a mystery caller approach (January to October 2024). Using a standardized script, team members inquired about mifepristone availability, Alberta's coverage plan, and dispensing.

Objectives: The rising prevalence of gestational diabetes (GDM) presents a challenge to health-care systems. Virtual care has emerged as a potential solution to alleviate this burden, but limited data exist on its effectiveness. In this study, we evaluated maternal and neonatal outcomes in individuals with GDM managed with virtual care vs in-person care.

Background: Equitable access to abortion care remains a challenge in public health. Current Canadian abortion reporting overlooks modern practices such as mifepristone medication abortion and has no access and equity metrics. We aimed to comprehensively analyse abortion care provision in Alberta (the fourth largest province in Canada, home to more than 4 million people) focusing on temporal trends in annual abortion rates and access disparities.

Article Synopsis
  • This study examines how the duration of breastfeeding (lactation) influences the onset and type of menopause in midlife women.
  • The analysis included nearly 20,000 women aged 40 to 65, revealing that longer breastfeeding is linked to a lower risk of experiencing natural menopause before age 50, as well as reduced early surgical menopause.
  • The findings suggest that breastfeeding may provide additional maternal health benefits by potentially delaying menopause and reducing risks associated with certain types of menopause.

Background: Pelvic organ prolapse (POP) increases in incidence and severity with aging. At least 1 in 4 women seek pelvic floor care and many more suffer with concurrent symptoms of bowel, bladder and sexual dysfunction, which can have a large impact on quality of life. It is estimated that 1 in 5 women will undergo surgery for POP.

Background: One in 5 females will have surgery to treat pelvic organ prolapse in their lifetime. Uterine-preserving surgery involving suspension of the uterus is an increasingly popular alternative to the traditional use of hysterectomy with vaginal vault suspension to treat pelvic organ prolapse; however, comparative evidence with native tissue repairs remains limited in scope and quality.

Objective: To compare 1-year outcomes between hysterectomy-based and uterine-preserving native tissue prolapse surgeries performed through minimally invasive approaches.

Objective: To determine the association between unilateral oophorectomy (UO) and age at natural menopause.

Design: Secondary analysis of survey data from Alberta's Tomorrow Project (2000-2022).

Setting: Prospective cohort study in Alberta, Canada.

Introduction And Hypothesis: The objective was to determine if mid-urethral sling (MUS) tensioning with a Mayo Scissor as a sub-urethral spacer compared with a Babcock clamp holding a loop of tape under the urethra results in differences in patient-reported outcomes and rates of repeat surgery over a 5-year follow-up.

Methods: Follow-up 5 years after a randomized clinical trial, utilizing primary data collection linked to administrative health data, was carried out to create a longitudinal cohort. The primary outcome was participant-reported bothersome SUI symptoms, as defined by the Urogenital Distress Inventory (UDI-6) questionnaire.

Introduction: Hysterectomy is a common surgery with discernible practice variations that could be influenced by socioeconomic factors. We examined the association between level of educational attainment and the occurrence and timing of hysterectomy in Canadian women.

Material And Methods: We conducted a prospective cohort study of 30 496 females in the Alberta's Tomorrow Project (2000-2015) followed approximately every 4 years using self-report questionnaires.

We investigated the time-varying association between parity and timing of natural menopause, surgical menopause, and premenopausal hysterectomy among 23 728 women aged 40-65 years at enrollment in the Alberta's Tomorrow Project cohort study (2000-2022), using flexible parametric survival analysis. Overall, natural menopause was most common by study end (57.2%), followed by premenopausal hysterectomy (11.

Objective: The objective of this work was to estimate the association between surgeon sex with surgical postponements or cancellations.

Summary Background Data: Female surgeons receive lower hourly, per patient, and total compensation than their male colleagues. Bias in the decision to postpone or cancel surgical cases may contribute to compensation inequality, since this results in unpaid surgeon time.

Introduction: Vaginal surgery has a superior outcome profile compared with other surgical routes, yet skills are declining because of low case volumes. Graduating residents' confidence and preparedness for vaginal surgery has plummeted in the past decade. The objective of the present study was to investigate whether procedure-specific simulation skills, vs usual training, result in improved operative competence.

Rationale & Objective: Female reproductive health is recognized as a predictor of morbidity, mortality, and quality of life, although data in the setting of chronic kidney disease (CKD) are limited.

Study Design: A mixed-methods study was employed. Phase 1 was an anonymous, internet-based survey.

Introduction: Our objective was to explore the relation between patient age and postoperative opioid use up to 24 hours following pelvic organ prolapse (POP) surgery.

Material And Methods: We conducted a prospective cohort study following 335 women ranging in age from 26 to 82 years who underwent surgery for multi-compartment POP at a tertiary center in Alberta, Canada. Patient characteristics were measured using baseline questionnaires.

Background: Up to 40% of patients aged ≤55 years undergo concomitant bilateral salpingo-oophorectomy at the time of benign hysterectomy, with practice variation in bilateral salpingo-oophorectomy occurring along the lines of patient health and social factors. Disability is common in premenopausal women and is an important determinant of reproductive health more broadly; however, studies on bilateral salpingo-oophorectomy rates among women with disabilities are lacking.

Objective: This study aimed to examine whether the use of concomitant bilateral salpingo-oophorectomy at the time of benign hysterectomy differs by preexisting disability status in adult females aged ≤55 years.

Study Question: What is the association between past infertility and the type and timing of menopause in midlife women?

Summary Answer: Women with a history of infertility were more likely to experience surgical menopause overall and had elevated risk of earlier surgical menopause until age 43 years but experienced no differences in the timing of natural menopause.

What Is Known Already: Infertility is experienced by 12-25% of women and is thought to reveal a propensity for poor health outcomes, such as chronic illness, later in life. However, little is known about whether infertility is linked with characteristics of the menopausal transition as women age, despite possible shared underlying pathways involving ovarian function and gynecologic disease.

Background: It is well established that female physicians in Canada are reimbursed at lower rates than their male counterparts. To explore if a similar discrepancy exists in reimbursement for care provided to female and male patients, we addressed this question: Do Canadian provincial health insurers reimburse physicians at lower rates for surgical care provided to female patients than for similar care provided to male patients?

Methods: Using a modified Delphi process, we generated a list of procedures performed on female patients, which we paired with equivalent procedures performed on male patients. We then collected data from provincial fee schedules for comparison.
