Intensive neurorehabilitation for patients with prolonged disorders of consciousness: protocol of a mixed-methods study focusing on outcomes, ethics and impact

BACKGROUND

Prolonged disorders of consciousness (PDOC) are amongst the severest sequelae of acquired brain injury. Evidence regarding epidemiology and rehabilitation outcomes is scarce. These knowledge gaps and psychological distress in families of PDOC patients may complicate clinical decision-making. The complex PDOC care and associated moral dilemmas result in high workload in healthcare professionals. Since 2019, all PDOC patients in the Netherlands have access to intensive neurorehabilitation up to 2 years post-injury provided by one rehabilitation center and four specialized nursing homes. Systematic monitoring of quantitative rehabilitation data within this novel chain of care is done in a study called DOCTOR. The optimization of tailored PDOC care, however, demands a better understanding of the impact of PDOC on patients, their families and healthcare professionals and their views on rehabilitation outcomes, end-of-life decisions and quality of dying. The True Outcomes of PDOC (TOPDOC) study aims to gain insight in the qualitative outcomes of PDOC rehabilitation and impact of PDOC on patients, their families and healthcare professionals.

METHODS

Nationwide multicenter prospective cohort study in the settings of early and prolonged intensive neurorehabilitation with a two-year follow-up period, involving three study populations: PDOC patients > 16 years, patients' family members and healthcare professionals involved in PDOC care. Families' and healthcare professionals' views on quality of rehabilitation outcomes, end-of-life decisions and dying will be qualitatively assessed using comprehensive questionnaires and in-depth interviews. Ethical dilemmas will be explored by studying moral deliberations. The impact of providing care to PDOC patients on healthcare professionals will be studied in focus groups.

DISCUSSION

To our knowledge, this is the first nationwide study exploring quality of outcomes, end-of-life decisions and dying in PDOC patients and the impact of PDOC in a novel chain of care spanning the first 24 months post-injury in specialized rehabilitation and nursing home settings. Newly acquired knowledge in TOPDOC concerning quality of outcomes in PDOC rehabilitation, ethical aspects and the impact of PDOC will enrich quantitative epidemiological knowledge and outcomes arising from DOCTOR. Together, these projects will contribute to the optimization of centralized PDOC care providing support to PDOC patients, families and healthcare professionals.

Clinical and advanced neurophysiology in the prognostic and diagnostic evaluation of disorders of consciousness: review of an IFCN-endorsed expert group

The analysis of spontaneous EEG activity and evoked potentialsis a cornerstone of the instrumental evaluation of patients with disorders of consciousness (DoC). Thepast few years have witnessed an unprecedented surge in EEG-related research applied to the prediction and detection of recovery of consciousness after severe brain injury,opening up the prospect that new concepts and tools may be available at the bedside. This paper provides a comprehensive, critical overview of bothconsolidated and investigational electrophysiological techniquesfor the prognostic and diagnostic assessment of DoC.We describe conventional clinical EEG approaches, then focus on evoked and event-related potentials, and finally we analyze the potential of novel research findings. In doing so, we (i) draw a distinction between acute, prolonged and chronic phases of DoC, (ii) attempt to relate both clinical and research findings to the underlying neuronal processes and (iii) discuss technical and conceptual caveats.The primary aim of this narrative review is to bridge the gap between standard and emerging electrophysiological measures for the detection and prediction of recovery of consciousness. The ultimate scope is to provide a reference and common ground for academic researchers active in the field of neurophysiology and clinicians engaged in intensive care unit and rehabilitation.
