LOINC long common name : NAACCR hospital tumor registration.permanent [Identifier];
LOINC short name : NAACCR hospital tumor reg.permanent;
LOINC description : The unique, non-repeating number automatically assigned to patients by the hospital
tumor registry software system. The same number is used for all the patient's subsequent
tumors. This Patient System ID-Hosp number should not be reused when a patient is
deleted. This number is different from Accession Number-Hosp [550]. While Accession
Number-Hosp [550] is subject to change, the Patient System ID-Hosp number is created
and maintained by the hospital tumor registry's software system, and requires no key
entry. Because the Patient System ID-Hosp number is unchanging, it affords an absolute
linkage between a hospital patient record and a central registry's patient record.
This provides a stable identifier to link back to all reported tumors for a patient.
It also serves as a reliable linking identifier; useful when central registries send
follow-up information back to hospitals. Other identifiers such as social security
number and medical record number, while useful, are subject to change and are thus
less useful for this type of record linkage. .. NAACCR Data Standards and Data Dictionary
