Research Suggests Caution in Early Decisions About Life Support Withdrawal In Coma Patients
While there isn't a precise figure for the number of coma patients removed from life support annually, several studies provide insights into this practice:
A study of 2,100 inpatient deaths found that withdrawal of life-sustaining therapy for perceived poor neurologic prognosis occurred in 25% of cases[3]. This was the sole contributing factor to death in 15% of patients.
In a study of patients with traumatic brain injury:
- 51% had life-sustaining measures withdrawn within 72 hours of injury
- 49% had life support withdrawn after 72 hours[5]
The practice of withdrawing life support varies significantly across medical centers:
- In a study of traumatic brain injury patients, withdrawal of life-sustaining therapy accounted for 70.2% of deaths
- This rate ranged from 45.0% to 86.8% across different centers[1]
Several factors contribute to decisions about withdrawing life support:
- Perceived poor neurological prognosis
- Patient age and injury severity
- Hospital type (teaching vs. non-teaching)
- Regional differences
It's important to note that some research suggests caution in making early decisions about life support withdrawal. A study found that 42% of patients who continued on life support and survived regained some independence up to 12 months after injury[2].
