Practising evidence-based medicine: the design and implementation of a multidisciplinary team-driven extubation protocol

BackgroundEvidence from recent literature shows that protocol-directed extubation is a useful approach to liberate patients from mechanical ventilation (MV). However, research evidence does not necessarily provide guidance on how to implement changes in individual intensive care units (ICUs). We conducted the present study to determine whether such an evidence-based strategy can be implemented safely and effectively using a multidisciplinary team (MDT) approach.MethodWe designed a MDT-driven extubation protocol. Multiple meetings were held to encourage constructive criticism of the design by attending physicians, nurses and respiratory care practitioners (RCPs), in order to define a protocol that was evidence based and acceptable to all clinical staff involved in the process of extubation. It was subsequently implemented and evaluated in our medical/ surgical ICU. Outcomes included response of the MDT to the initiative, duration of MV and stay in the ICU, as well as reintubation rate.ResultsThe MDT responded favourably to the design and implementation of this MDT-driven extubation protocol, because it provided greater autonomy to the staff. Outcomes reported in the literature and in the historical control group were compared with those in the protocol group, and indicated similar durations of MV and ICU stay, as well as reintubation rates. No adverse events were documented.ConclusionAn MDT approach to protocol-directed extubation can be implemented safely and effectively in a multidisciplinary ICU. Such an effort is viewed favourably by the entire team and is useful in enhancing team building.
