Value of hospital administrative data linked to national cancer registry records to identify metastatic disease at time of primary diagnosis in colorectal cancer patients: a study using national data in England.

ABSTRACT:

Background

Routinely collected data are increasingly being used for cancer research and health service evaluation. For both purposes, accurately identifying metastatic disease at diagnosis is essential. We developed an approach to identify metastatic disease at time of primary diagnosis according to national hospital administrative data (HAD) in patients identified with colorectal cancer (CRC) in the English national cancer registry (CR).

Methods
