Conversion of labour epidural analgesia to anaesthesia for operative delivery is common practice in obstetric units1.

Variations in epidural top-up practices among departments may lead to uncertainty and diverse approaches among junior trainees.

These variations could potentially increase the risk of errors, impacting patient safety and trainee morale2.

Our objective was to develop a cognitive aid to improve confidence and standardise practices among novice anaesthetists, thereby enhancing patient safety.
