After intracranial pressure control and sedation withdrawal, this population is prone to residual disorder of consciousness and altered neurological control of respiratory drive, cough and airway protection. Consequently, extubation failure is more frequent than in general ICU patients, and there is no clear evidence-based clinical trigger for extubation. Different risk factors for extubation failure were described in observational trials, and clinical scores were constructed to detect patients at higher risk of extubation failure. Nevertheless, none of these scores were prospectively tested as interventional tools to prevent extubation failure. The Brain-Injured Patients Extubation Readiness (BIPER) study is an ongoing multicentre stepped-wedge cluster-randomised controlled trial aiming to test one of these scores as an intervention protocol to decrease extubation failure in neurocritical care patients with residual disorder of consciousness.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and analysis<\/jats:title>\n                    <jats:p>Trial design: Stepped-wedge cluster-randomised controlled trial with five groups of three to six clusters (20 ICUs). Groups of clusters are randomised to five possible sequences of nine periods with crossing from a control condition period (usual care for extubation) to an intervention condition period (BIPER-guided extubation protocol), separated by a 3-month transition period.<\/jats:p>\n                    <jats:p>Participants: Participants are clinically stable brain-injured patients (18\u201375 years old), requiring more than 48 hours of invasive mechanical ventilation with residual disorder of consciousness after sedation withdrawal, and who achieved a spontaneous breathing trial.<\/jats:p>\n                    <jats:p>Interventions: The control condition consists of extubation based on usual care and local practice. The intervention condition consists of extubation triggered by a clinical score evaluating deglutition, gag reflex, cough and visual tracking (Coma Recovery Scale-Revised Visual Scale).<\/jats:p>\n                    <jats:p>Objective: To determine whether adoption of an extubation protocol based on a clinical score can lessen extubation failure compared with usual care in brain-injured patients with residual disorder of consciousness.<\/jats:p>\n                    <jats:p>Outcome: The primary outcome measure is extubation failure, defined within 5\u2009days following extubation. The key secondary outcome measure is time to effective extubation.<\/jats:p>\n                    <jats:p>Randomisation: Clusters are allocated to sequence of treatments using random blocks randomisation.
