This study compared closed and open intensive care unit (ICU) models in terms of patient outcomes. Closed ICUs had reduced mortality rates, shorter lengths of stay, and lower healthcare-associated infection rates. Intensivists in closed ICUs contributed to better outcomes due to their expertise and competence. Enhanced interdisciplinary collaboration, improved communication, and coordination in closed ICUs led to higher patient and family satisfaction.  In addition, closed ICUs were more cost-effective, with better resource use and reduced healthcare costs. Overall, closed ICU models have advantages in patient outcomes, better resource use, cost-effectiveness, and patient satisfaction compared to open ICU models.


Key words: Intensive care unit, ICU, patient outcomes, resource utilization, quality of care.
