Documentation during obstetrics spinal anaesthesia will demand accuracy and completeness for maternal and neonatal safety. Third year anaesthesia students are the pioneer participants in documentation of perioperative information. This audit aimed to improve the documentation trends of third year anaesthesia students after subarachnoid obstetric anaesthesia. Methods: It was conducted from April to May 13, 2019 in University of Gondar Referral Hospital at maternity wards. Data were analyzed with SPSS version 20. Categorical variables were analyzed with chisquare test. Results: Documentation completion was 58.2% before interventions and 81.13% after interventions. Documentation completion of hospital number, name of the surgeon and urine output significantly improved after interventions Conclusions: This audit identified significant improvements of post intervention documentation of patient's data such as patient height, preoperative blood pressure and baseline saturation. So, we recommend having regular lecturing and re-auditing of documentation trends of our third year anaesthesia students.
