What is the Japanese National Spinal Cord Injury Database?

Established in 1997, the Japan-Spinal Cord Injury Database (SCI-J) collects data of traumatic spinal cord injuries throughout Japan in a longitudinal multi-center medical study from thirty hospitals, and two spinal cord injury centers. *

* (Hospitals and Spinal Cord Injury Centers are associated with Japan Organization of Occupational Health and Safe, Kanagawa Rehabilitation Hospital, and Aijinkai Rehabilitation Hospital, Chiba Rehabilitation center, Kokura rehabilitation Hospital, St. Mary's Hospital.)

From 1997 until 2019, 5569 spinal cord injury cases were registered into a database, parameters include:

Demographic Information – Age, gender

Injury characteristics – Mechanism of Injury, neurological level of injury, extent of injury

Functional outcomes – Level of daily activity, management of bowel/bladder disfunction

Discharge outcomes – Patient’s home, institutionalized

The database is used as a foundation for producing conference presentations, articles, books, etc. Please feel free to use the following references and graphs in your research.
