Intervention acceptability
The intervention was consistently validated as technically straightforward to use and accommodate within routines of care. Although bedside nurses were aware of increased documentation, overall, they endorsed the ease and flexibility with which COMFORT scoring and SBT readiness screening could be undertaken. That the intervention explicitly accommodated independent clinical decision-making was considered particularly important for buy-in from unit consultants, who expressed no sense of being constrained in their decision-making regarding either the conduct of SBTs or patient extubation. The same independence was highlighted by nursing staff, primarily in relation to the management of patient sedation.
