Background to the collection
The monthly diagnostics waiting times and activity return collects data on waiting times and activity for 15 key diagnostic tests and procedures.
It contains aggregate level data submitted by providers, broken down by commissioner. The data measures the current waiting times of patients still waiting for 15 key diagnostic tests or procedures at the month end. This data is split by number of weeks waiting, and by test. Diagnostics test activity across the month is also collected broken down by waiting list, planned and unscheduled.
Data for this collection is available back to January 2006. The monthly diagnostics collection is used to measure performance against the diagnostic operational standard (less than 1% of patients should wait 6 weeks or more for a diagnostic test).
NHS England publishes the results each month. For further information and FAQs relating to the collection, please visit the NHS England website.
