The ISHLT Registry uses the following identifiers for record linking and data reporting:
ISHLT Patient ID Number
When a transplant is reported, the ISHLT Registry assigns it a unique number. This number serves as the primary linking number for individuals who are multiply transplanted. The ISHLT Patient ID Number is for registry use only and cannot be modified.
Patient 9IS Number
When a recipient is added in ISHLT, a 9IS Number will also be created automatically. This number servers as a primary identifier for the recipient. The 9IS Number can be modified.
ISHLT Hospital Number
The ISHLT Registry assigns a six-character code to uniquely identify each transplant center. This number is for ISHLT Registry use only and cannot be modified.
