  1. New VS Code extension to help with writing and testing ehrQL

    We have released a new extension for VS Code and Codespaces to help users test their ehrQL queries against tables of dummy data. You can read more in the documentation, or try it out by following the updated ehrQL tutorial.

  2. Updates to ehrQL tutorial

    We have recently published a significant update to the ehrQL tutorial. The tutorial now walks you through using ehrQL to identify patients who should be on the QOF register for diabetes, and to categorise patients on the register according to various QOF business rules. You can work through the tutorial…

  3. Improved handling of all_diagnoses and all_procedures fields

    We have added better handling for the all_diagnoses and all_procedures fields in the apcs table. These fields contain every diagnosis (ICD10 codes), and each procedure undertaken (OPCS4 codes), during a hospital spell. The field is a list of clinical codes, joined together with ,s and ||s (see the above links for more details on why).

  4. OpenSAFELY publication approval process update

    Dear OpenSAFELY users, If you have submitted work for publication approval, we appreciate your patience with our delay in providing a response. We look forward to sending you a response as soon as this is possible. A rapid review of the publication approval process was recently prompted by a number…

  5. OpenSAFELY data update

    Dear OpenSAFELY Users, We previously communicated that we had to temporarily remove all deregistered patients from the population available in OpenSAFELY-TPP. This was to ensure that we respected all Type 1 Opt-outs, and allowed us to reopen earlier, but introduced substantial difficulties with the representativeness and usefulness of the data.

  6. OpenSAFELY re-open in TPP

    In order to restart the OpenSAFELY service without further delay, we have put in place an interim measure to ensure that these type 1 opt-outs are respected.

  7. OpenSAFELY Update – July 2024

    There have been a number of significant changes to the NHS England (NHSE) OpenSAFELY service and governance recently. Unfortunately some of these changes mean that the service is effectively - temporarily - closed at this time.

  8. OpenSAFELY development environments hosted in GitHub Codespaces

    All research projects can now access OpenSAFELY development environments hosted in GitHub Codespaces.

  9. New ordering of workspaces on OpenSAFELY Jobs homepage

    What has changed? Once logged into OpenSAFELY Jobs, the 5 workspaces shown to you on your home page are now the five most recently active (by creation/modification date or most recently run job) that you have access to. This is a change from previously showing you the five most recently…

  10. Comparing study code on OpenSAFELY Jobs

    OpenSAFELY Jobs has always shown the Git commit hash for a given job request or job, with a link to view the workspace’s code on GitHub as of that revision. We now also provide GitHub code comparison links (example) so you can see exactly what code has changed between…
