Patient Safety Dashboard

The NHS Safety Thermometer has been removed as an official NHS Statistic. More details on this can be found in the document here.

It is also proposed that newly formed Central Measurement Unit for the Patient Safety Collaboratives will take on the formal role of analysing and presenting the Safety Thermometer data.

Due to these changes the Improvement Acadmey have decided that we will no longer continuing to update our Safety Thermometer dashboards. We will keep the April 2017 version here for reference.


This chart is used to show changes in performance over time using Statistical Process Control (SPC) rules. It uses a Mean average over the last 2 years, and show how the selected Trust compares to the Yorkshire & Humber, and the England average over the same time period. Look for a series of 8 points in a row above or below the Mean to indicate a step-change in performance. If there are any points outside the "Control Limits" this indicates special cause variation, and is worth investigating to understand this. If there are a number of these together, again this would indicate a step-change.

This information is based on the NHS Safety Thermometer data. For further information please see here. To feedback any comments or ideas for improvement please contact Michael Rooney (Senior Improvement Analyst) here.

 The chart above is used to compare between organisations for the latest month. A Trust outside the Control Limits is said to be statistically "different" to other Trusts within the limits. There could be many reasons for this, it is not necessarily due to better / worse care. The higher the number of patients who are surveyed each month, the tighter the limits.

The Safety Thermometer is best used with some caution when comparing Trusts, as no adjustment is made for the demographics of the patients in each Trust, and there are some differences in data capture and data quality between Trusts.
