Subjects and Methods
An observational prospective study was conducted. Patients aged >60 submitted to elective surgery and admitted to Post Anesthesia Care Unit (PACU) in a tertiary hospital from May to July 2017 were included. POD was evaluated with the Nursing Delirium Screening Scale (NuDESC). Quality of recovery-15 (QoR-15) was used before (T0) and 24 h (T24) after surgery to assess quality of recovery. Data collection include patient's characteristics, respiratory events at the PACU, and other perioperative variables. The Chi-square, Fisher's exact, or Mann-Whitney U-tests were used for comparisons.Results
Of a total of 235 patients, 12.3% developed POD at PACU. POD was more frequently in patients older than 80 years (P = 0.017), patients with neurological disease (P = 0.026), dementia (P = 0.026), peripheral vascular disease (P = 0.016), and diabetes mellitus (P = 0.037). At T0, there were no differences at median total QoR-15, whereas at T24, patients POD scored lower in 10 items (including "severe pain" with P = 0.001 and "nausea or vomiting" with P = 0.009) of QoR-15 and in total median lower scores (P = 0.001). POD patients stayed longer at PACU (P = 0.017) and they stayed longer at hospital (P = 0.002).
