Each enrolled patient will receive a business card listing the investigators' contact information and be advised to expect a follow up telephone call 6 months and 1 year after surgery to verify data elements and reassess functional outcome. Delirium will be assessed prospectively once per day on postoperative days 1, 2, and 3 by a trained study team member using the Confusion Assessment Method [CAM]. Delirium is most common on postoperative days 1-3 and the CAM is a well-validated measure of delirium in surgical patients. For functional status, the WHODAS will be administered 6-12 months postoperatively either by personnel in the surgeon's office as part of routine follow up or by study staff or by telephone. Investigators will also collect information on secondary outcomes including duration of PATC visit, presence of an advanced directive, whether they had surgical procedure, time to PACU discharge, discharge to place other than home (rehabilitation, skilled nursing facility), hospital length of stay (LOS), in hospital complications, perioperative variables including drugs administered, BIS, estimated blood loss, blood transfusions, fluid administered, blood pressure, oxygen saturation, 30-day reoperation or readmission rate, and 30-day and 1-year mortality. These outcomes are recorded in the medical record, the BWH Balanced Scorecard, an electronic database of all hospitalized patients that tabulates 31 elements of the hospital event, or the BWH Research Patient Database Enhanced Query. Data will also be confirmed by a follow up telephone interview. Thirty day and 1 year mortality will be recorded.
