Recovery Trajectory for Coma and Disorders of Consciousness (Coma Cohort)

2026年5月28日更新者：University of California, San Francisco

This study aims to better understand recovery after coma caused by serious neurologic illness or injury. Patients who are unconscious (in a coma or disorder of consciousness) due to conditions such as stroke, cardiac arrest, traumatic brain injury, seizures, brain infection, or other neurologic emergencies may be enrolled during their hospitalization.

The purpose of this observational research study is to learn which medical, neurologic, psychological, and social factors are associated with recovery over time. Researchers will collect information from the medical record during hospitalization, including details about the patient's illness, treatments received, brain imaging, and neurologic examinations.

For patients who survive hospitalization, the study team will contact participants or their caregivers after discharge to assess recovery at scheduled time points using questionnaires and structured interviews about physical function, quality of life, emotional well-being, and daily activities.

This study does not assign participants to any experimental treatment. Participation will not change the medical care patients receive. Information learned from this study may help improve future care for patients with coma and disorders of consciousness.

研究人群

Hospitalized adult patients with coma or disorders of consciousness resulting from acute neurologic injury or illness.

描述

Inclusion Criteria:

Age greater than or equal to 18 years on the day of hospital admission
Coma duration of at least 24 hours from presentation to the receiving hospital, or died prior to the 24 hour timepoint without return of consciousness. Coma defined as: GCS score of less than or equal to 10 AND GCS score of less than 6 on the motor component of the GCS(not following commands) AND GCS score less than 3 on the verbal component AND alteration of consciousness not explained by sedation only
Coma due to a neurological process (Including but not limited to: trauma, stroke, hypoxic- ischemic brain injury (HIBI), CNS infection, seizure, other processes at the discretion of the investigator)
Admission to the intensive care unit, or deceased prior to admission.

Exclusion Criteria:

Pre-existing score of 5 or less on the motor component of the Glasgow Coma Scale prior to hospital admission.
Transfer from another acute care hospital in which the motor component of the Glasgow Coma Scale on the day after initial hospital arrival is not known or cannot be reconstructed from medical records or history.
Coma due to sepsis, systemic metabolic processes (ex: organ failure or sedation).
GCS score of greater than 2 for eye opening with lack of command following due to a focal brain lesion causing receptive aphasia.

Modified Rankin Scale (mRS) 大体时间：1, 3, 6, 9, 12, 15, 18, 21, 24, 30, 36, 42, and 48 months after coma onset, with continued assessments at 6-month intervals thereafter until study completion	Functional outcome will be assessed using the modified Rankin Scale, a clinician-administered measure of global disability following neurologic injury. Scores range from 0 to 6, with higher scores indicating greater disability.	1, 3, 6, 9, 12, 15, 18, 21, 24, 30, 36, 42, and 48 months after coma onset, with continued assessments at 6-month intervals thereafter until study completion
