Description
This item indicates the Toronto Staging Version number that the Pediatric staging is based on. This data item is recorded based on when the case is abstracted.
Rationale
The Pediatric Staging API is based on the Toronto Staging System, so named because the definitions were first discussed at a meeting held in Toronto. Over time, the definitions will be revised, and the Pediatric staging API will be updated accordingly. This value captures the Toronto version which the current Pediatric Staging API is based on.
Codes
| 1 | First version of Toronto Staging (Pediatric Staging versions 0.3-0.5) |
| 2 | Second version of Toronto Staging (Pediatric Staging version 1.0 and later) |
