For the study, first published in 2006, the researchers examined how well NHS organisations had attempted to use the information they gathered from adverse clinical incidents and whether they were learning from it. By looking at existing relevant research worldwide, interviewing experts, surveying NHS organizations (acute, community and ambulance), consulting health care and other high-risk industry safety experts and NHS risk managers, and investigating case studies of good practice, they developed a model to assess how ready NHS systems were to learn from incidents. This is known as Safety Action and Information Feedback from Incident Reporting (SAIFIR).
