Association of Perioperative Daily Steps and Postoperative Recovery Among Surgical Patients

The Second Affiliated Hospital of Zhejiang University, School of Medicine

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.

Patients scheduled to undergoing elective surgery including thoracic surgery ,abdominal surgery, primary hip replacement and radical mastectomy will be recruited.The exclusion criteria are as follows: With preoperative unconsciousness; Day surgery (planned length of stay < 1 day); Wheelchair, walking aid or crutch were used before operation; Unable to walk due to physical limitations; The collection time of preoperative steps was less than 1 week; The patient refused to participate.

After recruitment and screening , the investigators will ask the participants to wear a smart band to record data of their daily steps , in addition the investigators will collect the peri-operative data of these participants which includes their rehabilitations and clinical outcomes.

Inclusion Criteria:

Patients scheduled to undergo elective surgery including thoracic surgery abdominal surgery, primary hip replacement and radical mastectomy ; Age≥18 ASA Ⅰ～Ⅲ Able to wear smart band

Exclusion Criteria:

With preoperative unconsciousness Day surgery (planned LOS < 1 day) Wheelchair, walking aid or crutch were used before operation Unable to walk due to physical limitations The collection time of preoperative steps was less than 1 week The patient refused to participate
