The Classic Safety Thermometer is a measurement tool for improvement that focuses on the four most commonly occurring harms in healthcare: pressure ulcers, falls, UTI (in patients with a catheter) and VTEs.

Data are collected through a point of care survey on a single day each month on 100% of patients. This enables wards, teams and organisations to: understand the burden of particular harms at their organisation, measure improvement over time and connect frontline teams to the issues of harm, enabling immediate improvements to patient care.

The tool was developed by a community of users who iteratively tested the tool to ensure it is quick and easy to use and gives useful information which can be used for local improvement. A full guidance document describing the development of the tool can be found above.
