The effects of a weaning protocol in ITU

Abstract

BACKGROUND: Protocol driven ventilator discontinuation procedures have reduced ventilator days for patients in Intensive Care Unit (ITU) and are associated with better patient prognosis. In order to improve successful extubations, a weaning protocol was created for the Mater Dei Hospital (MDH) ITU using evidence-based criteria.

AIM: The purpose of this audit was to assess whether implementation of a mechanical ventilation weaning protocol had an impact on successful extubations as well as improved clinician and nursing knowledge regarding weaning.

METHOD: A prospective study was carried out to assess successful extubations before and after implementation of a ventilation weaning protocol. Adult patients who were ventilated for more than 7 days were included in the study. A questionnaire about mechanical ventilation and weaning was distributed to ITU physicians and nurses before and after implementation of the weaning protocol.

RESULTS: We could not find any statistically significant differences in weaning success after the introduction of the weaning protocol. Information retention did not improve after usage of the protocol.

CONCLUSION: The introduction of an ITU weaning protocol at Mater Dei Hospital did not increase the number of successful extubations. Despite enhanced staff perception of weaning, a mechanical ventilation questionnaire did not improve retention of knowledge.
