Innovations and Challenges in Intermediate Respiratory Care Units: Toward Effective Integration into the Hospital System.

This review gives a comprehensive and nuanced appraisal of the current state of Intermediate Respiratory Care Units (IRCUs). It aims to evaluate the distribution of IRCUs in Spain, identify challenges and gaps in the current system and analyze the impact of IRCUs during the COVID-19 pandemic. A review of the evolution and current state of IRCUs was conducted. A search was performed on PubMed. Original articles were selected for analysis. Additionally, recommendation documents on IRCUs from SEPAR and other Scientific Societies were reviewed. The review analyzes the history and evolution of the IRCUs, their role and function, IRCU models, the evolution of admission criteria, and their efficacy and efficiency. IRCUs offer significant benefits by improving patient outcomes through accurate categorization and specialized treatment of severe pulmonary diseases, ensuring high-quality care. They reduce ICU admission rates, resulting in substantial cost savings for hospitals. Our analysis indicates that while IRCUs contribute positively to patient outcomes and resource optimization in Spain, there are significant challenges related to heterogeneity in unit structures, staffing, and resource allocation. Standardizing definitions and models may enhance the effectiveness and comparability of IRCUs across the healthcare system.
