Quality of Multidisciplinary Team Management in Healthcare-Associated Infection Prevention and Control and Its Impact on Multidrug-Resistant Organism Infections

This study aimed to evaluate the quality of multidisciplinary team (MDT) management in healthcare-associated infection (HAI) prevention and control, as well as its impact on multidrug-resistant organism (MDRO) infections. This was a retrospective, single-center study with a small sample size. A total of 400 patients admitted to the Departments of Critical Care Medicine or Orthopedics between January 2022 and December 2023 were divided into a control group (n = 200, receiving conventional HAI management) and an experimental group (n = 200, undergoing MDT management). Key outcomes included compliance with infection prevention measures (e.g., isolation signs, disinfection preparation, and dedicated item use), infection control results (e.g., hand hygiene, appropriate antibiotic use, and medical waste disposal), and HAI incidence rates (e.g., MDRO, urinary, pulmonary, bloodstream, and skin infections). Pathogen specimen submission and satisfaction scores were also analyzed. The experimental group demonstrated higher implementation rates of infection prevention and control measures, and better adherence to hand hygiene, disinfection and isolation, appropriate antibiotic usage, dedicated use of medical items, and medical waste disposal, compared to the control group (p < 0.05). MDRO and other infection rates were lower in the experimental group versus the control group (p < 0.05). Furthermore, the experimental group showed higher pathogen specimen submission and qualified submission rates and a lower infection rate before antibiotic use compared to the control group (p < 0.05). Healthcare workers in the experimental group reported greater safety awareness, awareness of HAI prevention and control, environmental management quality, and nursing service quality. Patients also expressed higher satisfaction with HAI management at discharge (p < 0.05). MDT-based management enhances the quality of HAI prevention and control, effectively reducing MDRO infection rates and improving healthcare outcomes. However, the relatively small sample size from a single center may limit the generalizability of the findings.
