In a sophisticated study recently released in the American Journal of Infection Control, Dr. Daniel J. Diekema and his team undertook an all-encompassing analysis on infection forbiddance recommendations. Their primary focus revolved around mitigating the spread and impact of methicillin-resistant Staphylococcus aureus (MRSA) within acute care hospital settings. The resulting discourse titled, ‘Challenging the Universality of Contact Precautions in MRSA Prevention: A Critical Appraisal of Recent Infection Control Guidelines,’ prompted a productive response from prominent health organizations.
Specifically, the key authors of the ‘2022 Update of the Society for Healthcare Epidemiology of America/Infectious Diseases Society of America/Association for Professionals in Infection Control and Epidemiology Practice Recommendations for Prevention of MRSA Infection and Transmission in Acute Care Hospitals’ responded. In tandem with this, the primary author of the 2022 Update, Kyle J. Popovich, MD, MS, shared valuable insights through an interview with Infection Control Today® (ICT®) concerning momentous alterations to the guidelines, agreements reached, introduction of MRSA-centric risk evaluations, difficulties linked to halting contact precautions, and customizing MRSA obstruction measures to the unique needs of individual health care facilities. With the critical updates unveiled, the 2022 practice recommendations for hindering MRSA infection are structured to better help different hospitals in the face of varying challenges.
Among the key updates are the relegation of antimicrobial stewardship from a hanging problem to an essential practice, and the inclusion of considerations for hospitals with strong horizontal prevention measures in place. Other important updates include tips on the use of active surveillance testing in certain patient populations, updates on decolonization therapy for MRSA colonization, and advice on universal or targeted decolonization for several unique populations.
Recognizing that MRSA risks and the corresponding benefits and risks of contact precautions vary among hospitals, the authors encourage risk assessments to assist facilities in making informed decisions on infection control measures, especially the use of contact precautions. They also highlight the issue of mass de-implementation of contact precautions and stress the importance of hospital-specific risk assessments in decision-making.
The 2022 Compendium emphasizes the variance in epidemiology and risk within hospitals, urging facilities to tailor MRSA prevention measures according to their specific contexts. It promotes a combination of risk assessment and adherence to basic infection control practices to manage MRSA transmission and infection rates, ideally moving the field towards a more precision-based approach to infection prevention strategies.
