Survey of American and Canadian General Surgeons' Perceptions of Margin Status and Practice Patterns for Breast Conserving Surgery

Although breast conservation surgery (BCS) is commonly performed, several aspects of the procedure remain controversial. We undertook a cross‐sectional survey to compare Canadian (CDN) and American (AM) general surgeons' reported BCS practice patterns to better understand the cross‐border differences in early‐stage breast cancer surgery care. A modified Dillman Method survey was mailed to 1,447 AM and 1,443 CDN surgeons. Factors evaluated included preoperative assessment, margin definition, surgical techniques, and re‐excision practices. The response rate was 26% and 51% for AM and CDN surgeons, respectively. There was variation in use of preoperative core biopsies. American surgeons required wider margins for invasive cancer and ductal carcinoma in situ, and more often recommend re‐excision for invasive cancer with 1 and 2 mm margins (p < 0.05). There was also variability in surgical techniques used for intraoperative margin assessment. Wide variation in BCS practice was observed, with some of this variability related to surgeon country.     

Developing simulation games to advance public health nursing competence in baccalaureate education

We describe the development of an innovative baccalaureate nursing education strategy for public health nursing. Virtual simulation pedagogy is known to be effective for acute care nursing practice while less known for public health nursing. Three Canadian nursing schools, the Canadian Association of Schools of Nursing (CASN), and the Canadian Alliance of Nurse Educators using Simulation (CAN-Sim) partnered to develop three public health nursing virtual simulation games. Learners work through unfolding population health scenarios, simulating public health nursing practice focused on entry level public health nursing competencies. Each game fosters clinical reasoning and collaborative, community decision-making to respond to population health issues during community assessment, evidence-informed health promotion planning, and evaluation processes. A companion guide was developed to support best practices in implementing virtual simulation and promote optimum student learning using the public health nursing games.     

A Long-Term Survivorship Comparison Between Cemented and Uncemented Cups With Shelf Grafts in Revision Total Hip Arthroplasty After Dysplasia

Long-term outcomes of cemented and uncemented cups were compared in patients with hip dysplasia who had undergone revision hip arthroplasty. Patients had uncontained superolateral acetabular defects reconstructed with a structural allograft. This retrospective study compared 18 cemented acetabular cups to 27 uncemented acetabular cups. Average follow-up was 216 months (range, 96-312). Nineteen acetabular cups (42%) failed due to loosening and were revised. The 10- and 20-year cup survival was 88% and 76% in the uncemented group and 67% and 36% in the cemented group. Log rank analysis showed this difference to be significant (P = .0077). Uncemented acetabular cups performed significantly better than cemented cups.     

Randomized clinical trial of three‐layer tubular bandaging system for venous leg ulcers

The safety and efficacy of three‐layer (3L) tubular bandaging as a treatment for venous ulcer healing has not been evaluated despite its use in many clinical settings to treat people with venous leg ulcers. We evaluated the safety and efficacy of 3L tubular bandage compared with short‐stretch compression bandage to heal venous ulcers in a multicenter, open‐label, parallel‐group, randomized controlled trial. We randomized 45 patients with venous leg ulcers of up to 20 cm² area and an ankle brachial pressure index of >0.8 from hospital outpatient wound clinics in Victoria and Queensland, Australia. We measured time to healing and percentage reduction of wound size from baseline to week 12. Secondary outcomes were proportion of ulcers healed, self‐reported compliance of compression bandage, and health‐related quality of life, costs, recurrence rates, and adverse events. A total of 27 ulcers healed, the proportion of healed ulcers was higher for the 3L group (17/23 [74%] vs. 10/22 [46%]) (p = 0.05). Reported bandage tolerance at all treatment visits was 21 (91%) in 3L group vs. 17 (73%) (p = 0.10). There was no difference between the groups in adverse events. Costs were substantially less in 3L group.     

Review article: Use of the Team Emergency Assessment Measure in the rating of emergency teams' non-technical skills: A mapping review

The present study aims to explore the utility of the Team Emergency Assessment Measure (TEAM) in relation to the enhancement of emergency team non-technical skills based on research conducted over the last decade. In this mapping review, a citation mining process identified 22 primary studies for inclusion, published between 2012 and 2022. It provides outcome data on emergency teams' non-technical skills following team training and/or real-life patient emergencies. Emergency team studies related to resuscitation teams (adult, paediatric, newborn and obstetric cases) and medical emergency team (MET) management of patient deterioration. Team performance ratings varied, ranging from approximately 90% for experienced clinical teams down to 38% for students. Statistically significant improvements in performance were notable following training and/or repeated practice. Validity evidence, across 11 studies that provided change data described positive learning outcomes and moderate intervention effects. However, according to Kirkpatrick's model of educational evaluation the studies were limited to professional development phases of learning and immediate post-training assessments rather than care quality improvement. The review highlights a lack of studies evidencing quality improvement or clinical impact such as change of patient care practice or health service performance. There is a need to conduct well-designed studies that explore both technical and non-technical skills of resuscitation teams and METs. Currently, non-technical skills training and repeated performance evaluations using the TEAM contribute immensely to the proficiency of emergency teams.
