Outcome of "unknown" head injury patients at a tertiary care neurosurgical centre.
BACKGROUND
A large number of patients are admitted to hospitals in large cities without any identification. These "unknown" patients represent a unique problem in developing countries. There is no systematic study in world literature on this subgroup of patients.


OBJECTIVE
To elucidate the natural history and outcome of traumatic brain injury patients admitted in the department of neurosurgery as "unknowns".


METHODS
Retrospective analysis of all traumatic brain injury patients admitted to the department of neurosurgery as "unknown", between January 2002 and March 2005.


RESULTS
Three hundred and twenty five patients were admitted as unknowns over a 3 year and 3 months period. Most of the patients were young males and became known during their hospital stay. Overall, 33 patients stayed for longer than one month, with 4 of them staying for longer than 6 months. Mortality in mild, moderate and severe head injury group was 1%, 6% and 46% respectively.


CONCLUSIONS
Unknown patients represent a unique subgroup in metropolitan cities like Delhi. Managing them raises several medico-legal issues. Many of them occupy hospital beds for longer duration than required. There is an acute shortage of rehabilitation homes in Delhi for long term care and rehabilitation of such patients.
