856 Mortality and Morbidity Meetings in Oral and Maxillofacial Surgery: Hindsight is 20/20

Aim Mortality and Morbidity (M&M) meetings form a critical part of clinical governance however they often suffer from hindsight bias and lack objectivity. To combat this, Kahoot surveys were disseminated to senior clinicians prior to M&M meetings. Each case to be discussed is presented as a survey item with the clinical and radiographic information that was available to the performing surgeon pre-operatively and participants are asked to detail their ideal treatment. The aims of this study were to determine if the introduction of Kahoot surveys prior to M&M meetings improves the objectivity of the discussions and reduces the effects of hindsight bias. Method A 12-item questionnaire relating to the introduction and utility of Kahoot surveys prior to M&M discussions was distributed to all registrars and consultants within our department. Result An 80% response rate was obtained (16/20 responses). Prior to the introduction of Kahoot surveys, 62.6% of surgeons felt case discussions were clouded by the benefit of hindsight. Comparatively, 68.8% indicated the use of pre-M&M surveys reduced the effects of hindsight bias. 56.3% of participants expressed the objectivity of case discussions improved and 50% felt the quality of feedback improved. Conclusions The use of Kahoot surveys prior to M&M meetings demonstrates that withholding the case outcome until each clinician has given their own opinion reduces the effect of hindsight bias. The surveys utilise the Bolam Test, thereby enabling us to determine the correct error classifications with greater objectivity. Furthermore, they facilitate a higher quality of discussion and feedback.
