临床试验雷达

Patients who are being scheduled for an operative procedure with an inpatient postoperative stay are eligible for this study. Participants will be selected to start a physical fitness plan or a nutrition plan at the time of surgical scheduling. Each participant will be asked to continue their current lifestyle for two days after their pre-operative appointment to get a baseline of activity (by pedometer and functional tests) and nutritional risk (by questionnaire). After two days, patients in the activity group will start their activity plans. They will be encouraged to get 10,000 steps per day and to perform whole body strength training exercises 3 times a week. Five days before and after surgery, participants in the nutrition group will be asked to consume a standard liquid nutrition supplement (i.e. Boost or Ensure) two times per day. Participants in the activity group will record steps and number of strength training sessions completed, while patients in the nutrition group will record the number of supplements consumed.

Increases in physical activity and nutritional status are associated with improvements in a number of health conditions, including coronary artery disease, hypertension, stroke, insulin sensitivity, osteoporosis, and depression. Regretfully, despite the evidence supporting the benefits of physical activity, greater than half of adults in the United States do not get adequate activity and approximately one quarter do not get any activity. As such, many people, especially the elderly and those with comorbid diseases, have low levels of physical fitness. Additionally, up to 45% of community dwelling older adults are malnourished. Patients undergoing surgery with poor exercise tolerance and suboptimal nutritional status may be at an increased risk of perioperative complications. Thus, increasing physical activity and dietary intake quality prior to surgery is recommended, to hopefully decrease these risks. The primary objective is to determine if recommended physical activity or dietary intake results in an increase in patient physical function performance and if so, to what extent. The secondary goal is to examine if increased exercise or nutrition reduces perioperative complications.
