Predictiveness of preoperative laboratory values for postoperative delirium.

Background: Postoperative delirium (POD) is a common postoperative complication, especially in patients over 60 years, with an incidence ranging from 15% to 50%. In most cases, POD manifests in the first 5 days after surgery. Multiple contributing risk factors for POD have been detected.

Functional intervention following cardiac surgery to prevent postoperative delirium in older patients (FEEL WELL study).

Background: Postoperative delirium is a common complication in patients after cardiac surgery, especially in older patients, and can manifest as a disturbance of attention and consciousness. It can lead to increased postoperative morbidity, prolonged need for care, and mortality. The presented study investigates whether the occurrence of postoperative delirium after cardiac surgery can be prevented by a multisensory stimulation.

PRe-Operative Prediction of postoperative DElirium by appropriate SCreening (PROPDESC) development and validation of a pragmatic POD risk screening score based on routine preoperative data.

Study Objective: To develop and validate a pragmatic risk screening score for postoperative delirium (POD) based on routine preoperative data.

Design: Prospective observational monocentric trial.

Setting: Preoperative data and POD assessment were collected from cardiac and non-cardiac surgical patients at a German university hospital.

Postoperative delirium is an independent factor influencing the length of stay of elderly patients in the intensive care unit and in hospital.

Purpose: Postoperative delirium (POD) is an often unrecognized adverse event in older people after surgery. The aim of this subgroup analysis of the PRe-Operative Prediction of postoperative DElirium by appropriate SCreening (PROPDESC) trial in patients aged 70 years and older was to identify preoperative risk factors and the impact of POD on length of stay (LOS) in intensive care unit (ICU) and hospital.

Methods: Of the total 1097 patients recruited at a German university hospital (from September 2018 to October 2019) in the PROPDESC prospective observational study, 588 patients aged 70 years and older (mean age 77.
