Association of Perioperative Daily Steps and Postoperative Recovery Among Surgical Patients

Walking is the most common, simple and convenient way of exercise with the lowest cost. Studies have shown that daily steps are related to important health outcomes such as cardiovascular events and all-cause mortality. Catrine et al. believe that daily steps can be used as a basic index to evaluate physical fitness. Many observational studies have found that postoperative daily steps collected by wearable devices or smart phones are related to length of hospital stay or even postoperative depression, which is suggested that the average daily steps may be an important index to predict the prognosis of patients. So the investigators aim to explore the association between peri-operative average daily steps and postoperative recovery of patients scheduled for elective surgery.
