Added resources management argument to opensafely run
command
Updated: 31 August 2022
Users of the OpenSAFELY platform use the opensafely
tool to run their code
locally prior to running against the real data.
This change adds some options to control the concurrency and memory usage of running actions, which should help users manage their local resource usage.
Added with_at_least_one_day_in_critical_care
filter to admitted_to_hospital
Updated: 10 August 2022
Added ability to filter a patient’s hospital admissions to only those with at least one day in critical care.
Platform status page
Updated: 02 August 2022
We have rolled out a status page for the platform. Services on this page will be automatically updated if incidents occur.
Clarification about referrals data
Updated: 29 June 2022
We have clarified in the documentation that data on referrals is incomplete. Any codelists which include referral codes used with patients.with_these_clinical_events
are unlikely to return complete data as it is largely held separately in a difficult-to-analyse format. We hope to offer an alternative data source for referrals in due course.
Oxford/AstraZeneca vaccination name change
Updated: 17 June 2022
The name of the Oxford-AstraZeneca vaccine has changed to COVID-19 Vaccine Vaxzevria 0.5ml inj multidose vials (AstraZeneca)
. To continue to access data for these vaccines, all users will need to update study definitions appropriately.

Show how to extract cohortextractor output in compressed gzip (csv.gz) format - recommended to be used in all studies to minimise file storage size. (However, CSVs can still be used where Stata is used for analysis).
This is now shown in all parts of documentation with cohortextractor steps.
