A framework for measuring safety
Any single measurement of safety is likely to be over-simplified. For example, standardised mortality ratios (as a marker of safety) may be unreliable due to their dependence on administrative data and inability to provide a comprehensive overview of safety. There is no single valid measurement of safety and organisations need to use a variety of measurements and methods to evaluate the care they deliver.
Charles Vincent and colleagues have developed a framework with five classes of information to give an idea of how safe an organisation is.

Importantly, this framework does not focus only on past harm, but also current performance, future risk and organisational resilience. It does not recommend any single measure and emphasises that using a single measure of safety is insufficient.
Illingsworth summarises the practical applications of this framework as follows:
- Managers and frontline health professionals should reflect on the utility of data collected and rationalise measures used or introduce new ones.
- Board members and senior executives should actively seek information about hazards and risks, and not just react to previous harm caused.
- Government, regulators and national bodies should encourage organisations to demonstrate safety using both local and centrally mandated measures.
