Are Canadian Outpatient Ambulatory Surgery Centers Safe? An Assessment of 2596 Consecutive Aesthetic Surgery Patients.

Background: Ambulatory surgery centers (ASCs) with same-day discharge criteria are the most common setting for aesthetic surgery in Canada. However, to date, no study has reviewed the safety of outpatient aesthetic surgery performed in the Canadian ASC setting.

Objectives: The purpose of this study was to evaluate the overall safety profile of aesthetic surgery in ASCs, to determine how often in-hospital resources were utilized following outpatient aesthetic surgery, and to examine how predictor variables impact adverse outcomes in this setting.

Same-Day Discharge Ambulatory Surgery Centers: The Importance of Preoperative Workup for Aesthetic Surgery Patients.

Background: Limited resources combined with an increasingly "cost-conscious" approach to healthcare has resulted in a reduction of those preoperative investigations deemed unnecessary. Although this approach may work in the hospital setting where ancillary services and emergency support are readily available, it may actually be impacting patient safety in the ambulatory surgery center (ASC) setting.

Objectives: The purpose of this study was to determine the prevalence of abnormal results arising from routine preoperative workup amongst patients undergoing aesthetic surgery in the outpatient ASC setting.

Beyond the Surface: Assessing GPT-4's Accuracy in Detecting Melanoma and Suspicious Skin Lesions From Dermoscopic Images.

Self-examinations for skin cancer detection are limited by sensitivity. ChatGPT-4 has image recognition capabilities that can be a useful adjunct for screening cancers and tele-health applications. This study investigated the efficacy of ChatGPT-4 in identifying skin lesions.

The Impact of Surgical Wait Time and Hospital Stay on the Incidence of Burn Wound Infection and Related Complications at a Single Tertiary Hospital Centre: A 10-Year Experience.

Admitted patients with burn injuries require prompt treatment and shorter hospital stays to avoid hospital-acquired infections and associated complications. This study aimed to determine the impact of time to the first surgery, and total length of hospital stay on the incidence of BWI and associated complications in adult patients with moderate burn injuries at a single tertiary hospital burn center. A retrospective chart review identified burn patients admitted to the Burn Unit between January 2011 and January 2021.

Non-Breast Implantable Medical Devices and Associated Malignancies: A Systematic Review.

Innovation in healthcare has led to the development of numerous implantable medical devices (IMDs). However, advances in our knowledge of breast implant-associated malignancies have raised questions about the prevalence, etiology, and management of malignancies associated with non-breast IMDs. The objective of this study was to examine the prevalence and characteristics of malignancies associated with non-breast IMDs.

ChatGPT-3.5 and Bing Chat in ophthalmology: an updated evaluation of performance, readability, and informative sources.

Background/objectives: Experimental investigation. Bing Chat (Microsoft) integration with ChatGPT-4 (OpenAI) integration has conferred the capability of accessing online data past 2021. We investigate its performance against ChatGPT-3.

Aesthetic Refinements in Male Chest Lifting.

The authors describe aesthetic refinements to the approach for male chest lifting in male patients with grade 3 gynecomastia and/or significant chest skin excess. An inferior pedicle is used to transpose the nipple-areolar complex allowing preservation of pigment and sensation, liposuction and direct excision are used to reduce volume and excess skin, and the resulting curvilinear scar along the inferior and lateral border of the chest provide a more masculine appearance. Early experience with this technique has shown it to be safe and effective.

Refining the thoracic surgical oncology regionalization standards for esophageal surgery in Ontario, Canada: Moving from good to better.

Background: The consolidation of surgical practices has been suggested to improve patient outcomes for complex surgeries. In 2005, Ontario Health-Cancer Care Ontario released the Thoracic Surgical Oncology Standards to facilitate the regionalization process at thoracic centers in Ontario, Canada. This work describes the quality-improvement process involved in updating the minimum surgical volume and supporting requirement recommendations for thoracic centers to further optimize patient care for esophageal cancer.

A Canadian Experience With Off-the-Shelf, Aseptically Processed, Costal Cartilage Segment Allografts in Complex Rhinoplasty.

Background: Complex primary and secondary rhinoplasties usually necessitate grafting materials when native nasal cartilage is inadequate for reconstruction. Fresh frozen, aseptically processed, and nonterminally sterilized costal cartilage segment allografts (CCSAs) are a novel grafting material for such cases that avoid donor-site morbidity, improve operating efficiency, and mitigate the postoperative risks.

Objectives: To report the early experience using fresh frozen, aseptically processed, and nonterminally sterilized CCSAs used in complex primary and secondary rhinoplasties, in Canada.

Reconstruction of Large Defects Using Extended Temporomandibular Joint Patient-Matched Prostheses.

Purpose: Custom temporomandibular joint (TMJ) prostheses are useful in reconstructing large defects following TMJ resection. The purpose of this study is to evaluate the feasibility of extended-temporomandibular joint replacement (e-TJR) for reconstructing these defects.

Methods: This is a single-group retrospective cohort study that enrolled patients having received an e-TJR between January 2004 and November 2019 at the University of Toronto.

Restructuring Skin Cancer Care in Ontario: A Provincial Plan.

There is a global rise in skin cancer incidence, resulting in an increase in patient care needs and healthcare costs. To optimize health care planning, costs, and patient care, Ontario Health developed a provincial skin cancer plan to streamline the quality of care. We conducted a systematic review and a grey literature search to evaluate the definitions and management of skin cancer within other jurisdictions, as well as a provincial survey of skin cancer care practices, to identify care gaps.

Clearing the surgical backlog caused by COVID-19 in Ontario: a time series modelling study.

Background: To mitigate the effects of coronavirus disease 2019 (COVID-19), jurisdictions worldwide ramped down nonemergent surgeries, creating a global surgical backlog. We sought to estimate the size of the nonemergent surgical backlog during COVID-19 in Ontario, Canada, and the time and resources required to clear the backlog.

Methods: We used 6 Ontario or Canadian population administrative sources to obtain data covering part or all of the period between Jan.
