Brief summary
The focus of this study is the development of a perioperative treatment concept for elderly patients, based on individual necessities and risk factors, aiming to improve patient outcome. The planned interventions include preoperative screening for malnutrition, frailty and uncalled-for long-term medication, if required followed by early prophylaxis and treatment of these risk factors, prior to or during surgery.
Detailed description
In Germany every second inpatient surgical intervention is performed on patients aged 60 years and above. These patients often offer an extensive set of risk factors such as frailty, malnutrition, poor physical fitness and multi-morbidity that may in turn lead to longer hospitalizations and decline of health and functional status after surgery. An age-related increase in postoperative complications, such as postoperative cognitive dysfunction (POCD) and delirium is associated with a higher rate of postoperative morbidity, mortality and longer hospitalization. Early detection of risk factors and implementation of prophylactic measures is important to reduce postoperative complications and improve clinical outcomes in elderly patients. The aim of our study is to develop and verify a protocol - which allows for a systematic evaluation of risk factors and the implementation of prophylactic or therapeutic measures in order to optimize the postoperative outcome. The feasibility of our protocol will be verified in clinical practice by systematic process evaluations.
Interventions
Systematic inclusion of family members/ reference person in the perioperative process
Detailed preoperative information about delirium prevention and procedures
Preoperative execution of physical and breathing exercises if necessary
Dietary supplements if necessary
Avoidance of unsuitable drugs for elderly if possible
Regional anesthesia whenever possible
Personal orientation aids until anesthesia induction
Perioperative warming
Using Bispectral index (BIS) to measure the depth of anesthesia
A pain catheter will be used as postoperative pain therapy if possible

Study design
Intervention model description
The study has 3 arms with patients allocated to them in a fixed chronological order. For six months, patients will be recruited for the control arm. In this arm, participants receive usual care without any additional intervention initiated by the study. After finishing recruitment for the control arm, patients will be recruited for the implementation arm for six months. In this arm, stepwise implementation of the study interventions begins with the possibility of flexibly adapting them to the specific conditions. After finishing recruitment for the implementation arm, patients will be recruited for the full-scale intervention arm for six months. In this arm, all study interventions will be utilized.
