Background: Special technical issues arise in medical devices in intensive care units (ICU) that are related to their function and maintenance. This study explored the level of comfort of different ICU staff in dealing with selected equipment, the factors are associated with the staff’s ease of adaptation of new technologies, and the role of technical support staff. Methods: This is a single center cross-sectional questionnaire-based survey that was conducted in February2018 and targeted nurses working in the ICUs of King Saud University Medical City (KSUMC) in Riyadh, Saudi Arabia.Results: Among the 297 nurses who completed the survey, almost all of the respondents (99.3%) were aware of their ICU preventive equipment maintenance program. Most of the nurses received training on how to use infusion pumps (96.2%), cardiac monitoring systems (78.0%), and cardiac defibrillation devices (73.9%). Sixty nurses (20.2%) indicated that at least one super user was available for at least one device. About half of the staff reported one device whose user manual was available. Regarding updates on medical devices, most nurses reported they had no resource for the update. Conclusions: The findings revealed an alarming need to address technical issues related to medical devices used in the ICU and to design a framework for the safe operation of medical devices based on international practices. It is necessary to empower the role of the super user and medical device clinical educator as well as optimize communication between the national regulatory body of medical devices and healthcare providers, especially those working in acute care areas.
