Surgical checklists such as ‘World Health Organization (WHO) Surgical Safety Checklist’ are made to make surgery safer, simple and to reduce human errors. Similar to this concept, Ali M et al and others have implemented the ‘haemostasis checklist’ and it had shown reduction in incidence of re-exploration in patients who underwent surgery using cardiopulmonary bypass (CPB). However, there is still scarcity of literature about the effect of these checklists on re-exploration after off-pump coronary artery bypass grafting (OPCABG).
