What this trial studies

This observational study aims to develop and validate the SWADOC tool, designed specifically for assessing swallowing disorders in patients with disorders of consciousness (DOC) following severe brain injuries. The study will involve a multicentric prospective cohort of 104 patients who will be evaluated three times over two consecutive days using the SWADOC tool. The researchers will analyze the relationship between the patients' level of consciousness and their scores on the SWADOC assessment. This tool is intended to improve the evaluation and therapy of dysphagia in this vulnerable patient population.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old who have experienced a coma due to severe acquired brain injury and have a diagnosis of disorders of consciousness.

Not a fit: Patients who have pre-existing neurological or otorhinolaryngological conditions affecting swallowing prior to their brain injury may not benefit from this study.

Why it matters

Potential benefit: If successful, this tool could significantly enhance the assessment and management of swallowing disorders in patients with severe brain injuries, leading to better patient outcomes.

How similar studies have performed: While the SWADOC tool is a novel approach, similar studies have shown the importance of tailored assessment tools for improving patient care in dysphagia and disorders of consciousness.
