Anesthesia Quality Improvement and Patients With Planned ICU Admission

Effects of Anesthesia Quality Improvement on Outcomes of Patients With Planned ICU Admission: a Prospective Pre-post Intervention Study

Intensive care unit (ICU) is an important part of perioperative management for high-risk patients but is associated with higher medical costs. Improper ICU admission may produce overtreatment without beneficial effects. In clinical practice, delayed recovery after general anesthesia is a common indication for ICU admission after surgery. The concept of Enhanced Recovery After Surgery recommends early extubation. The investigators suppose that, for patients with planned ICU admission after elective surgery, implementing anesthesia quality improvement including extubation in the operating room will reduce the rate of ICU admission after surgery without increasing complications.

Detailed Description

Intensive care unit (ICU) is an important part of perioperative management for high-risk patients but is associated with higher medical costs. Improper ICU admission may produce overtreatment without beneficial effects. Studies found that immediate ICU admission after surgery did not reduce the perioperative mortality. Some authors suggested that the indication of ICU admission should be the occurrence of postoperative complications, which will reasonably reduce the use of medical resources.

In clinical practice, delayed recovery after general anesthesia is a common indication for ICU admission after surgery. Old age, high ASA grade, respiratory complications, long duration surgery, large-volume fluid infusion, and use of vasopressors were main factors associated with delayed recovery. The concept of Enhanced Recovery After Surgery recommends early extubation after surgery. Studies showed that, for patients after organ transplantation, immediate extubation in the operating room can shorten hospital stay and reduce medical costs, without increasing mortality.

The investigators suppose that, for patients with planned ICU admission after elective surgery, implementing anesthesia quality improvement including extubation in the operating room will reduce the rate of ICU admission after surgery without increasing postoperative complications.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Incidence of postoperative complication	Postoperative complications are defined as newly occurred medical conditions that are considered harmful to patients' recovery and require therapeutic intervention, that is grade II or higher on Clavin-Dindo classification.	Up to 30 days after surgery

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Length of stay in hospital after surgery	Length of stay in hospital after surgery	Up to 30 days after surgery
Rate of ICU admission	Rate of ICU admission	On the 1 day of surgery
Incidence of postoperative delirium	Delirium is assessed with the Three-dimensional Confusion Assessment Method (3D-CAM) twice daily (8:00-10:00 am and 18:00-20:00 pm).	Up to 5 days after surgery
Medical costs during hospitalization	Medical costs during hospitalization	Up to 30 days after surgery
Rate of delayed neurocognitive recovery	Cognitive function is assessed with the Montreal Cognitive Assessment (MoCA) before surgery and at discharge. A decrease of 1 standard deviation (SD) or more from baseline is defined as the development of delayed neurocognitive recovery.	up to 7 days after surgery

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
All-cause 30-day mortality	All-cause 30-day mortality	Up to 30 days after surgery
Length of stay in ICU after surgery	Length of stay in ICU after surgery	Up to 30 days after surgery
Duration of mechanical ventilation	Duration of mechanical ventilation	up to 30 days after surgery
Rate of ICU re-admission	ICU re-admission is defined as ICU admission from the general wards after surgery	Up to 30 days after surgery
