We need more studies to guide the perioperative management of high risk seniors undergoing surgery

The number of surgical procedures in the ambulatory care setting in the United States has increased by over 300% during the past decade with over 30 million ambulatory surgeries (AS) being performed yearly [1]. Of these, 6 million are done in seniors (≥65years of age) and, with the aging of the US population, the number of seniors undergoing surgery will expand exponentially. In addition, more complex surgeries (e.g. hysterectomy, thyroidectomy, spine surgery) are also now conducted in the ambulatory setting [2–4].
