"And do no harm": Complications in interventional neuroradiology

Five psychological mechanisms that might bias learning from neurosurgical complications: case discussions and a narrative review

PURPOSE

The ability of neurosurgeons to analyze and reflect on their complications in a constructive way is important both for professional development and for patient safety. The purpose of the present paper is to highlight some psychological factors that might impair or bias the ability of the neurosurgeon to do this successfully.

METHODS

Five fictitious cases, loosely inspired by real events and situations, are used as a basis for a discussion of some of the most important potential sources of psychological bias in the context of understanding neurosurgical complications.

RESULTS

The issues of a) self-serving bias and the actor-observer effect; b) heuristics and biases in interpreting probabilistic events; c) emotional avoidance and denial; d) limitations of attention (dual systems theory) and e) errors of memory, are discussed.

CONCLUSION

There are a number of psychological factors, that are well known to science that may be ubiquitous sources of influence on the ability of neurosurgeons to grow by reflection on their own complications. Exactly how these factors can and should be efficiently adressed by the individual neurosurgeon and/or the organisation and team in which the neurosurgeon works may vary according to type of bias, context and circumstances. However, being aware of these issues and addressing them on an individual and organizational level remains important to the quality of our craft.
