UK regulators incorrectly use the absolute number of Never Events to assess hospital safety. This method is mathematically invalid because it ignores hospital workload, leading to inaccurate performance evaluations.
Area of Science:
- Healthcare quality and safety
- Medical statistics
- Health services research
Background:
- UK regulators use the absolute number of Never Events to evaluate hospital safety performance.
- This approach does not account for variations in hospital workload, potentially skewing assessments.
Purpose of the Study:
- To assess the validity of using absolute Never Event numbers for hospital performance evaluation.
- To investigate the impact of hospital workload on Never Event rates using funnel plots.
Main Methods:
- Analysis of published Never Event data from 151 NHS England acute Trusts (2017-2020).
- Application of funnel plots to account for hospital workload (finished consultant episodes).
- Correlation analysis between absolute Never Event numbers and workload.
Main Results:
- A significant correlation was found between Never Events and workload (r² = 0.51, p < 0.001).
- Hospitals with statistically excess Never Event rates did not consistently have the highest absolute numbers.
- Data exhibited skewness, with 12 out of 151 Trusts falling below the lower confidence limit.
Conclusions:
- Current regulatory use of absolute Never Event numbers for judging hospital performance is mathematically unsound.
- A shift is needed from identifying outlier hospitals to reducing the national average Never Event rate.
- Promoting shared learning and a system-wide approach is crucial for improving overall patient safety.
