Abstract Aim This audit aimed to evaluate and improve the results of microvascular breast free flap reconstruction by implementing an enhanced perioperative care approach. Method All microvascular breast free flap reconstructions between June to August 2023 were included. Additionally, a three year retrospective review was conducted in adherence to ABS and the BAPRAS guidelines. Our team plans to introduce an evidenced-based modified Enhanced Recovery After Surgery (ERAS) protocol via MDT collaboration with a focus on pre-operative and post-operative care to improve postoperative outcomes. Results During June – August 2023, 22 flaps were performed with an average length of stay (LOS) of 5.47 days (target <3d). There were no unplanned readmissions, an 18% return to theatre (RTT) rate and a total complication rate of 18%. Over the past three years, out of 323 flaps, there was a 13% RTT rate with no unplanned readmissions. Suggested modifications to reduce length of stay include pre-surgical counselling and nutritional loading. Post-operatively, using a multi-modal opioid sparing analgesia (MOSA) regime, along with laxatives, early mobilisation and feeding has proven to enhance recovery. Pre-admission patient optimisation, VTE and perioperative antibiotic prophylaxis have been shown to reduce rates of flap failures and post-operative complications. Effective wound care, post-discharge support and physiotherapy are also crucial in accelerating recovery and preventing readmissions. Conclusion Implementing these ERAS modification to our current protocol is predicted to significantly improve post-operative recovery, thus improving surgical outcomes. This underscores the potential for continual improvement in patient care through an efficient evidence-based perioperative pathway.
