The purpose of SARs is described very clearly in the statutory guidance as to ‘promote effective learning and improvement action to prevent future deaths or serious harm occurring again’. The aim is that lessons can be learned from the case and for those lessons to be applied to future cases to prevent similar harm re-occurring. What SARs are not is also explained: The purpose of a SAR is not to hold any individual or organisation to account. Other processes exist for that purpose, including criminal proceedings, disciplinary procedures, employment law and systems of service and professional regulation run by the Care Quality Commission (CQC) and the Nursing and Midwifery Council, the Health and Care Professions Council, and the General Medical Council, etc.
Yet it can be difficult to keep a focus on the learning in the face of terrible abuse or neglect, media and public interest. This is especially so if it appears at first that ‘human error’ was to blame for the failure to prevent it. Four ideas are put forward below to support a focus on learning:
Hindsight bias poses a great obstacle to learning through SARs. The tendency to ‘consistently exaggerate what could have been anticipated in foresight’ (Fischhoff 1975) is a well reproduced research finding – the ‘knew it all along’ effect (Vincent 2006).
When we review professional practice in retrospect, the outcomes of tragic cases powerfully shape the way in which we make sense of practitioners’ actions and decisions. Knowledge of the outcome biases our judgement about the process that led up to that outcome. Firstly, the benefit of hindsight leads us to oversimplify the situation confronting the practitioners who were involved at the time. Secondly, we judge decisions or actions that are followed by a negative outcome more harshly than if the same decisions or actions had ended either neutrally or well. Blaming bad outcomes on simple causes such as human error literally seems to make sense because knowledge of the outcome changes our perspective so fundamentally (Woods, Dekker et al. 2010).
A person exhibiting the hindsight bias will typically ask questions such as: ‘Why didn’t they see what was going to happen? It was so obvious!’. Or, ‘How could they have done X? It was clear it would lead to Y!’ (Woods, Dekker et al. 2010: 203). SABs will therefore need to ward against this bias in the commissioning and quality assuring of SARs if the SARs are to produce learning that has potential to underpin improvement.
