Audit on Practices of Endotracheal Suctioning in Intensive Care Unit Patients among Health Care Workers (HCWs)

Abstract

Background: Endotracheal suctioning (ETS) is one of the most frequently performed invasive procedures in intensive care units (ICUs). This audit was aimed at studying current practices and knowledge regarding ETS in the Indian critical care setup, with the background aim of raising awareness regarding correct practices as per current recommendations in critically ill patients.Materials and methods: After registering the trial with the clinical trial registry, India, a structured audit questionnaire containing 20 questions pertaining to ETS was distributed through electronic media among resident doctors working in the ICUs across India. Responses received were statistically analyzed. Results: The questionnaire was sent to 530 clinicians, of which only 200 (37.73%) responded. The audit revealed that only 22% respondents set the maximum negative pressure every time before suctioning, on the suction apparatus and only 32% said they would choose a catheter size of less than half the internal diameter of the endotracheal tube (ETT). About 90% of the respondents did not routinely do any form of documentation of the ETS. Almost 72% of the responders opined that closed suction systems reduce the chances of developing ventilator-associated pneumonia (VAP). Only 46% of respondents thought that no solution should be routinely instilled in ETT during ETS. Conclusion: There is lack of awareness regarding frequency and technique of ETS, infection control and monitoring required during ETS. Institutional protocols should be in place to follow correct guidelines for performing ETS.
