Organisations should no longer collect ‘classic’ or ‘next generation (Medication, Mental Health, Maternity and C&YPS)’ Safety Thermometer data or submit it to the Safety Thermometer portal. Information on replacement metrics drawn from routinely collected data can be found on the Patient Safety Measurement Unit webpage.

The Safety Thermometer, launched in 2010, was one of the largest and longest-lasting data collection exercises in NHS history. It had a powerful impact in its early years. But more recent evaluations, research and feedback have shown that the data was incomplete, and it was no longer able to support improvement in the intended way. Because of this, new data sources were explored that could take the burden of data collection away from clinical staff and support new improvement initiatives. Ending the Safety Thermometer were publicly consulted on in 2019/20 as part of proposed changes to the NHS Standard Contract. The response supported ending the national collection of Safety Thermometer data from April 2020, and using alternative data sources to continue improving pressure ulcer prevention, falls prevention, VTE prevention and prevention of healthcare-associated infection.

All data collection for the ‘classic’ Safety Thermometer and the ‘next generation’ Safety Thermometers will therefore stop after March 2020. Plans for nationally-produced replacement data to support improvement drawn from routinely collected sources will be provided or signposted on the NHS England and NHS Improvement Patient Safety Measurement Unit webpage as soon as possible.

Very easily! The process of getting your organisation set up and submitting can be done in a few minutes. If you wish to have your organisation set up in the ST, you would need to send an email to This email address is being protected from spambots. You need JavaScript enabled to view it. with the following information:

  • Full organisation name
  • Organisation code (If you're not sure what this is, you can find it here: https://odsportal.hscic.gov.uk/Organisation/Search )
  • Which email address to assign Administrator rights to (Remember, the admin can add, edit and delete new users - so you decide how you submit!)
  • Which thermometer(s) does your organisation need access to (Classic, Medications, Mental Health, Maternity, Children & Young Peoples)

We will then set up your organisation and you're ready to go! Please note, although it may appear blank, we will still have your previous submissions via the excel tool. By request we can back-load all of your previous data and wards to your organisation, but this may take some time - so don't panic that it's not there!
