In this episode, Thomas K Varghese, Jr, MD, FACS, is joined by Carrie Chan, MSN, MPH, from the University of California, San Francisco, and Karthik Balakrishnan, MD, FACS, from Stanford Medicine Children’s Health. They discuss their recent article,“Development, Validation, and Comparison of Machine Learning Models for Predicting Pediatric Surgical Site Infections Using the NSQIP-P Database,” which represents the largest study to date on predicting pediatric surgical site infection. The authors developed machine-learning models and ultimately recommend a regularized logistic regression model for clinical integration, balancing performance and feasibility for implementation. Findings support using routine preoperative data for personalized infection prevention and preoperative planning.

Disclosure Information: Ms Chan and Drs Varghese and Balakrishnan have nothing to disclose.

In this episode, Thomas K Varghese, Jr, MD, FACS, is joined by Laurie J Kirstein, MD, FACS, from Memorial Sloan Kettering. They discuss Dr Kirstein’s recent article, “Results of an American College of Surgeons Prospective National Quality Improvement Collaborative to Successfully Overcome Barriers to Cancer Care Across the US,” in which 194 American College of Surgeons (ACS)-accredited cancer programs caring for 99,057 patients participated in a National Quality Improvement Collaborative led by the ACS, “Breaking Barriers,” which reduced radiotherapy non-adherence by over 30% at the patient and hospital levels across multiple program types, census regions, and disease sites.

In this episode, Lillian Erdahl, MD, FACS, is joined by Jessica Liu, MD, MS, MPH, from the Department of Surgery, Harbor UCLA Medical Center. They discuss Dr Liu’s recent article, “Identifying Diagnostic Gaps and Mitigation Strategies for Older Adult Emergency General Surgery Patients: A Scoping Review,” in which the authors identified the current diagnostic issues, clinical tools, and clinician feedback strategies in the older adult emergency general surgery (EGS) setting. While challenges unique to older adults exist, variability in the use of tools to improve identification of older adult conditions in EGS and gaps in feedback to improve diagnosis remain.
