Cancer Waiting Times


The national Cancer Waiting Times (CWT) system allows NHS providers to record data derived from patient care activity. This data can be used to monitor cancer waiting times targets or plan service improvements. As a patient moves through the stages of their treatment pathway data on referrals, treatments and diagnosis are derived from care records locally (decisions on how to collect these data from local systems are made locally).

After collection, the cancer waiting times data can be queried by NHS organisations, cancer networks and the Department of Health to provide reports and feedback on the progress towards meeting these targets.

The Addendum to the National Cancer Waiting Times Monitoring Data Guidance v.9.0 provides guidance about the Inter Provider Transfers and Faster Diagnosis Standard requirements of cancer waiting times and seeks to ensure that staff from both informatics and clinical teams understand the data they need to be reporting on.
