Abstract Aim Immediate handover of a postoperative patient to a critical care team is vital for in-patient management. Smooth and accurate exchange of information avoids unnecessary clinical incidences. Local trust guidelines direct towards 100% completeness of handover sheet in the electronic system. Goal to achieve 100% completeness of theatre handover form. To receive all relevant information from personnel involved in care. Method A total number of 100 post-cardiac surgery patients were admitted to Critical Care immediately after surgery in both cycles from June to July and October. Data were collected retrospectively, which includes both elective and emergency procedures. Results In 1st cycle, information from surgeon to CCA doctor accounts for around 50%. Information from anaesthetists and theatre nurses were 88% and 90%, respectively. In the 2nd cycle, handover from the surgeon, anaesthetist, and theatre nurse was approximately 60%, 95% and 90% gradually. Specific postoperative instruction was recoded 30% for 1st round, whereas it was around 45% in reaudit. Conclusions A proper handover is crucial for managing postoperative cardiac surgery patients because inadequate pre-and postoperative information can lead to a serious error. Considering the audit finding, it seems advisable to take a more multidisciplinary approach to improve the standard of postoperative patient handover care with complete information transformation.
