The definition of day surgery in Great Britain and Ireland is that the patient is admitted and discharged on the same day, with day surgery as the intended management.
Since the previous guideline of 2011, the complexity of procedures has continued to increase, with a wider range of patients now considered suitable for day surgery. However, the overall rates of day surgery remain variable across the UK. The target that 75% of elective surgery should be performed as day cases remains in place, but minimally invasive surgery is now well established, allowing more procedures to be performed as day surgery and even greater rates should be possible. Shortened hospital stay and earlier mobilisation also reduce the risk of hospital-acquired infections and venous thromboembolism.
