Managing your cohort
How to update and manage your cohort.
What to expect after submitting your cohort file
When managing your cohort between data extracts, keep the following in mind:
- it is your responsibility to manage your cohort and ensure that any updates are submitted before your data extract is due
- following the first cohort submission and dissemination of data, you will receive a reminder to update your cohort 5 days before your next data dissemination is due
- when updating your cohort, ensure that you include information within the status column, which can be add or delete
- failure to update your cohort within the given timescales will result in data being provided based on the cohort that NHS England currently holds; any additional extracts required due to late changes may incur additional payment
