Inspection of Isolation Rooms Based on Standards, a Cross-Sectional Study in the COVID-19 Crisis

Abstract

Background: Following the COVID-19 pandemic, the significant vulnerability of healthcare facilities, particularly hospitals, in the context of acute respiratory syndrome outbreaks has been highlighted. Given the critical role of hospital services, it is essential to assess the preparedness of hospitals to manage the spread of pathogens. Isolation rooms represent one of the most critical areas in hospitals for infection control. Objectives: This study aimed to evaluate hospital isolation rooms and compare their conditions with established standards. Methods: In this cross-sectional study, 33 isolation rooms across 13 different hospitals in Mashhad were examined in 2020. The degree of compliance with standard conditions was assessed using a checklist based on regulatory standards for isolation rooms. The checklist included items related to room sealing, air inlet and outlet conditions, pressure warning systems, and the pressure differential between the isolation room and adjacent areas. Additionally, the proper use of HEPA filters was evaluated. Results: The findings indicated that in 81.8% of cases, there was no evidence of air recirculation to the isolation rooms, meeting the relevant standard. However, the required configuration of the air inlet positioned above the patient’s head and the air outlet at the foot of the bed was not observed in 72.8% of the rooms. All rooms met the standards regarding door width and the minimum distance between beds. Conclusions: This study revealed that a substantial proportion of isolation rooms do not meet standard conditions in several critical areas. Such deficiencies pose significant risks during outbreaks of infectious diseases like COVID-19, potentially endangering both healthcare providers and immunocompromised patients.
