    Abstract

    In the last two decades, there is a growing awareness that medical errors constitute a big challenge harming both patients and providers around the world. There is also an increasing attention on the potential implication of safety culture on patient and provider safety and quality of care delivered. To investigate such relationship between safety culture and medical errors, a number of studies have been conducted. While most studies focused on particular safety culture dimension, such as teamwork and leadership, there is very limited understanding on capturing potential interaction between safety culture dimensions and their overall impact on the rate of observed medical errors affecting both patients and providers. To shed light on this, this research used aggregate staff survey data from the British National Healthcare Service (NHS) to capture what safety culture dimensions drive observed medical errors. Through the application of machine learning approaches and algorithms, such as random forest modelling, the study results showed that 'role of team members and managers' is the main driver as safety culture dimension, while particular statement 'supervisor's feedback on staff work' is the key driver affecting the rate of observed medical errors to both patients and providers. Understanding such drivers is helpful for decision makers to utilize resources and enhance safety culture effectively to accelerate patient and provider safety in healthcare.
