Using quality improvement to pursue equity: lessons from healthcare

Against a backdrop of stalling life expectancy, the COVID-19 pandemic highlighted the need to tackle inequities in healthcare. Quality improvement has become an increasingly recognised way of tackling complex problems in healthcare. This article presents a step-by-step approach for the use of quality improvement to pursue equity at an NHS provider in England. The Model for Improvement was used to set an aim, develop a theory of change and measures, and test change ideas through plan-do-study-act cycles. A five-step sequence of improvement was used to provide a structured approach to identifying and tackling problems. Projects were designed to use a time series testing strategy in which baseline data were collected, a change was introduced and data continued to be collected over time to assess improvement. The results of three teams that have demonstrated sustained improvements were analysed using statistical process control charts. The teams' achievements included a 27% increase in access to early intervention mental health services for ethnic minority groups; a 92% reduction in racist incidents on inpatient wards; and a reduction in the gap between cervical screening rates for different age groups from 8% to 3%. Quality improvement offers those closest to the delivery of care a way of systematically making improvements in equity. Further opportunities for the field include the use of experimental designs to test combinations of interventions and potential scalability of quality improvement methods across systems with multiple partners.
