[Perioperative strategies: taking care of the elderly patient with severe advanced comorbidities needing acute surgery.].

In the common clinical practice the perioperative risk assessment of an acute surgical patient with advanced chronic comorbidities is carried out independently by surgeon and anesthesiologist, usually in two different steps. While the surgeon evaluates the risk mainly in relation to the surgical outcome, the perioperative risk assessment regarding the weight of the coexisting medical condition on the quality of recovery in the short- mid- and long-term is all about the anesthesiologist evaluation. When frailty and/or comorbidities are so serious that will make surgery seem futile, the patient's assessment on one hand, and the decisions regarding the further clinical waypoint on the other, have to be discussed firstly between surgeons and anesthesiologists before being shared with the patients and their relatives. This is mostly true in the event of an emergency surgical procedure. In regard, a consensus conference attended by a panel of experts respectively from the Italian Society of Anesthesia Analgesia Resuscitation and Intensive Care (SIAARTI) and the Italian Society of Surgery (SIC) was called for developing a shared clinical pathway aimed to select the best care option - operative vs palliative - in the best interest of the surgical patient with advanced chronic comorbidities, in emergency or elective condition. After two years, the panel of experts developed a position paper recommending, in case of potentially futile surgery, to assess the patient verifying two coexisting conditions ("Two Steps method"): Palliative Performance Scale <50%, and at least one of the following general clinical criteria: 1) more than one hospital admission within the last 12 months; 2) hospital admission from or awaiting admission to long-term care facilities, home care service, hospice; 3) chronic renal failure requiring weekly dialysis sessions; 4) home oxygen use and/or non-invasive ventilation. Under these conditions, the surgeon together with the anesthesiologist can share with the patient and/or his relatives the decision between palliative surgery or palliative care taking into account his wishes and preferences.
