Background: Early post-operative complications contribute substantially to preventable morbidity, unplanned ICU admissions, and prolonged hospital stay in Australian surgical services. Although evidence-based protocols exist, effective translation into bedside care during the first 48 hours after surgery depends largely on junior doctors, particularly after hours. Observational data demonstrate persistent gaps in confidence and execution relating to analgesia titration, venous thromboembolism prophylaxis, drain assessment, and escalation of clinical deterioration. These gaps represent a modifiable driver of surgical hospital-acquired complications and align with National Safety and Quality Health Service Standard 5. Methods: Module X: Foundations of Evidence-based Post-operative Care was developed as an eight-hour blended educational intervention for postgraduate year 1–2 medical officers in a regional surgical service. The curriculum integrates flipped learning, case-based discussion, ward-based simulation, and supervised bedside skills practice. Educational design aligns with Miller’s Pyramid of Clinical Competence and Kolb’s experiential learning cycle. Core content targets five high-impact complications: surgical-site infection, post-operative haemorrhage, venous thromboembolism, respiratory failure, and acute delirium. Performance is assessed using structured viva, simulation-based OSCE checklists, mini-CEX, and guided reflective debriefs. Results: The programme was designed for feasibility within existing teaching structures, requiring no additional capital investment and a faculty-to-learner ratio of 1:6. A needs analysis identified low baseline confidence in analgesia adjustment (71%), drain interpretation (58%), and escalation pathways (54%), informing curriculum priorities. Conclusion: A structured, context-adaptable educational intervention targeting junior-doctor post-operative decision-making is a scalable strategy to improve early surgical safety, particularly in regional settings.
