Optimising Health before Elective Surgery
Based on the evidence review for smoking cessation and weight reduction in the obese (BMI 30kg/m2 or above), it is recommended that all patients should be offered appropriate lifestyle change support before or at the time of referral for elective surgery and that this is consolidated and verified at assessment for elective surgery.
This is supported by the evidence that stopping smoking before elective surgery reduces the risk of intra- and postoperative complications, impaired wound healing and incidences of surgical site infections, which contribute to length of stays in hospital and the cost of health care.
It is also recommended that patients who are obese with a BMI of 30kg/m2 or above should be engaged in a behavioural change conversation. Obese patients should be signposted to self-help advice or offered referral to a specialist lifestyle behaviour change service for weight reduction support as appropriate.
