Structural models for intermediate care areas

Objective: To describe structural models of intermediate care units used fo r critically ill patients. Data Sources: Three multidisciplinary units with varying structures and fun ctions of intermediate care areas (ICAs) are described. Data Synthesis: Advantages and limitations for each of the three models are outlined. The structural models described are the conventional isolated IC A model, the parallel model, and the integrated model of IGA. Conclusion: Each structural model has advantages and limitations. Selection of the appropriate ICA model for an institution depends on the specific ci rcumstances and needs of the institution. Each of the three models can faci litate improved utilization of critical care resources.
