Development of protocolized care in the intensive care unit (ICU) improves patient outcomes, but presents multiple challenges. A mechanical ventilation weaning protocol (WP) was adopted in our institution but was underused. This study aimed to determine the factors that influenced the implementation of this protocol locally.

We performed a qualitative descriptive study using semidirected interviews in small profession-specific focus groups. The interviews were based on a standardized guide covering the major domains found in the Consolidated Framework for Implementation Research. A total of 32 participants across four key professions were recruited. The interviews were transcribed and codified sequentially, followed by categorization and analysis.

Three broad factors emerged that negatively impacted the implementation of the WP. First, the goals of the WP differed between professional groups. This difference led to significant frustration and breaches in collaboration. Second, there was a lack of a continuous quality improvement process. Third, the WP was incompatible with the routine and procedures already in place at the time of implementation. Time-of-day of WP application and patient safety concerns were specifically identified issues.

Implementation of a continuous improvement process with regular and specific follow-up may help identify potential challenges and thus help ensure a more consistent use of the WP.
