Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Delirium	The primary outcome will be delirium occurring on postoperative day one. Delirium will be assessed using the Confusion Assessment Method (CAM) twice daily. Delirium will be defined as present if either the morning or afternoon assessment are positive for delirium.	Postoperative day 1
Secondary	Delirium	Postoperative delirium will also be assessed as a secondary outcome assessed within the first three days after surgery, and separately within the first seven days following surgery. Delirium will be assessed using the CAM in the same fashion as the primary outcome. In the event the patient is reintubated the CAM-ICU may also be used to assess for postoperative delirium as a secondary outcome.	Postoperative Day 1 to Day 7
Secondary	Delirium Severity	Delirium severity will be assessed using the CAM-Severity (CAM-S) within the first three days following surgery, and separately within the first seven days following surgery. The CAM-S ranges from 0 (no delirium features) to 19, with higher scores indicating worsening delirium severity.	Postoperative day 1 to day 7
Secondary	Telephonic Montreal Cognitive Assessment	Global cognitive function will be assessed with the T-MoCA in-hospital and at three time points after hospital discharge. Different versions of the T-MOCA will be administered at each time point to minimize learning effects. The T-MoCA ranges from 0 (worst) to 22 (best) points, does not require visual cues or writing, and importantly, can be administered over the phone.	30, 180 and 365 days
Secondary	Global Health	Global health will be assessed at 30, 180 and 365 days using the Patient Reported Outcome Measurement Information System (PROMIS) 29 Profile version 2.1. This assessment results in several subscale scores, each reported as a t-score.	30, 180 and 365 days
Secondary	Pain at Rest and Upon Exertion	Pain will be assessed within the first seven days following surgery, using a trajectory of pain scores at rest and upon exertion/deep breathing. Pain scores will be elicited from patients daily using the Pain Numeric Rating Scale.	Postoperative day 1 to day 7
Secondary	Opioid and Analgesic Administration	Outcomes for opioid administration will evaluate the (a) frequency and (b) total consumption, defined as morphine equivalents, in the first 24 and 48 hours postoperatively. These will be captured based off medical record review.	48 hours postoperatively
Secondary	Hospital Length of Stay	Hospital length of stay will be defined as the number of days after surgery until the time of discharge from the hospital.	Postoperatively until discharge, an average of six days
Secondary	Intensive Care Unit Length of Stay	Intensive Care Unit (ICU) length of stay will be calculated as the time from discharge from the initial index ICU stay minus the time of admission into the cardiovascular ICU and will be reported in hours.	Postoperatively until discharge, an average of 24 hours
Secondary	Readmission	Hospital readmission will be evaluated within the first 30 days postoperatively using the Society for Thoracic Surgery database or via patient report during follow up phone calls.	30 days postoperatively
Secondary	Inpatient Morbidity	Major cardiac events will be evaluated within 30 days postoperatively and include stroke, atrial fibrillation and renal failure. These outcomes will be assessed using the Society for Thoracic Surgery database and medical record review.	30 days postoperatively
Secondary	Mortality	All-cause mortality will be assessed in-hospital and at 30, 180 and 365 days postoperatively. Mortality will be assessed using a combination of electronic medical record review, Society for Thoracic Surgery database, and family report during the follow up phone calls.	Postoperatively until discharge, an average of six days, and at 30, 180 and 365 days postoperatively
