• Episode 57: Revisiting Return-to-Work Policies: Preventing Respiratory Virus Transmission in Healthcare

  In this episode of The ICHE Podcast, Editor-in-Chief David Calfee is joined by Drs. Catherine Passaretti and Michael Klompas for a timely discussion on healthcare-acquired respiratory viral infections (HA-RVIs). Together, they explore how frequently these infections occur, the primary sources of transmission—including infected healthcare personnel (HCP)—and the infection prevention strategies aimed at minimizing risk. Dr. Passaretti walks listeners through her recently published letter proposing updates to current HCP return-to-work guidelines following COVID-19 infection. She explains the rationale behind the proposal, citing key concerns with existing guidance. Dr. Klompas then discusses two papers: one by Stone et al., which investigates the impact of current return-to-work policies, and another by Klompas himself, which reflects on the broader implications and outlines additional strategies to reduce HCP-to-patient transmission risk. The episode concludes with actionable insights from each participant, offering practical steps that healthcare facilities can implement today to enhance respiratory virus prevention and reevaluate HCP return-to-work protocols based on evolving evidence and epidemiology. This conversation offers valuable guidance for healthcare leaders, infection preventionists, and policy makers navigating a post-COVID landscape.

• Episode 56: Initial Specimen Diversion Devices (ISDDs) for Preventing Blood Culture Contamination

  In this episode of the ICHE Podcast, we explore the critical issue of blood culture contamination and the role of initial specimen diversion devices (ISDDs) in reducing false-positive results. Host Dr. David Calfee is joined by a distinguished panel of experts including: Dr. Maria Navas, Dr. Mark Rupp, Dr. Lucy Tompkins, and Dr. Francine Touzard Romo. The discussion begins with an overview of blood culture contamination—what it is, how it happens, and why it matters for patient care. Our experts examine the prevalence of contamination and its consequences, including unnecessary antibiotic use, prolonged hospital stays, and increased healthcare costs. The conversation then shifts studies recently published in ICHE on ISDDs—what they are, how they function, and whether they are an effective solution. Drs. Tompkins, Touzard Romo, and Navas share insights from their recent studies, followed by a discussion on the challenges of adherence in clinical settings. Dr. Rupp presents additional data to round out the discussion. At the conclusion of today’s episode, each expert offers a practical tip for healthcare professionals considering ISDD implementation in their institutions.

• Episode 55: Research Needs in Healthcare-Associated Infections (HAIs) and Antimicrobial Stewardship (AS)

  On this episode of The ICHE Podcast, we dive into research priorities in healthcare-associated infections (HAIs) and antimicrobial stewardship (AS) with experts Robin Jump, Jennie Kwon, Daniel Livorsi, Lona Mody, and Eli Perencevich. The discussion explores the importance of publishing research agendas to stimulate focused research, guide researchers in prioritizing critical topics, and inform funding decisions. By addressing these goals, the panel aims to align research efforts with pressing clinical challenges, foster innovation, and bridge gaps between research and implementation. The guests also discuss the structured methodologies used to draft these research agendas, detailing how key priorities were identified and refined to address the most urgent needs in the field. The panel reviews three recently published agendas in ICHE: A Call to Action: The SHEA Research Agenda to Combat Healthcare-Associated Infections, Research Agenda for Transmission Prevention within the Veterans Health Administration, 2024–2028, and Research Agenda for Antibiotic Stewardship within the Veterans Health Administration, 2024–2028. Key topics include addressing antimicrobial resistance, improving diagnostic tools, and tackling HAIs in vulnerable populations. The conversation further examines the applicability of findings from VA-specific agendas to non-VA healthcare settings, concluding that many insights are broadly relevant. Listeners will gain a clearer understanding of the research landscape and actionable ways to contribute to advancements in patient safety and healthcare quality.

• Episode 54: Infection Prevention in Obstetrical Populations: Insights into Group A Streptococcal Infections

  In this episode of the ICHE Podcast, guests discuss the prevention and management of infections in obstetrical populations, with a focus on Group A Streptococcal (GAS) infections. Hosted by ICHE Editor-in-Chief, Dr. David Calfee, the episode features Dr. John Conly, Dr. Shandra R. Day, and Dr. Kiran M. Perkins. The discussion begins with an overview of GAS infections in healthcare settings, particularly in the peripartum period, highlighting the unique challenges associated with these infections. The guests explore strategies for healthcare-associated GAS infection prevention, including practical approaches and solutions to overcome implementation barriers. Each expert shares insights from their recent research, addressing questions their studies aimed to answer, the methods they used, key findings, important limitations, and the broader implications of their work for infection prevention. Together, they emphasize the importance of understanding risks specific to labor and delivery units and the critical need for evidence-based practices to mitigate these risks. The episode concludes with actionable advice from each guest, providing concrete steps facilities can take to assess and reduce the risk of GAS infections in obstetrical settings.

• Episode 53: Respiratory Culturing Appropriateness in Pediatric Patients

  In this episode of the ICHE podcast, we explore the theme of respiratory culturing appropriateness in pediatric patients, emphasizing diagnostic stewardship's role in optimizing patient outcomes. Host David Calfee, MD, MS and guest experts, Kathleen Chiotos, MD, MSCE and Edward Lyon, DO, MA, share insights on how stewardship practices can refine respiratory testing in pediatric intensive care units (PICUs), where evidence suggests these tests are often overused without clinical benefit. They examine challenges in implementing stewardship, including barriers like resistance to change and logistical issues, and discuss practical strategies to overcome these obstacles. The conversation highlights two recent studies published in ICHE: Dr. Lyon's work on repeat tracheal aspirate cultures in PICUs, which analyzes their frequency, resistance patterns, and impact on antimicrobial use, and Dr. Chiotos's study on a tracheal aspirate culture stewardship intervention, examining its effect in a tertiary PICU. Both authors discuss their studies' methodologies, findings, limitations, and implications for future practice. To wrap up, each expert offers actionable recommendations for healthcare professionals interested in improving respiratory culturing practices at their institutions, providing practical steps to enhance safety and care efficiency. Full versions of the articles discussed in this episode are available in the September issue of ICHE.
