Delirium in Old Age

Brief summary

The project "QV-POD-2" is a prolongation based on "QV-POD-1", which was a quality contract program of the IQTIG - Institute for Quality and Transparency in Health Care. The aim is to improve inpatient care for older patients who are undergoing inpatient surgery and thus to specifically reduce the postoperative risk of delirium. This is achieved through the implementation of evidence-based and consensus-based measures to prevent postoperative delirium in a comprehensive structured concept in routine care. The transparent documentation in an electronic patient file enables the relationships between the symptoms to be depicted in accordance with the clinical circumstances and the genesis of the postoperative delirium to be recorded and treated at an early stage. The content of the additional elements from the routine data (see primary and secondary outcome measures) in QV-POD-2 is analysed internally. Subproject Retro-Pressure started in August 2022: Retrospective, exploratory cohort study using electronic anesthesia and hospital records from Jan 1, 2016 to Jan 1, 2020, including patients ≥70 years undergoing surgery with anesthesia. The objective is to quantify associations between intraoperative blood pressure dynamics-variability, rate of change, relative hypo-/hypertension versus baseline, and time-integrated BP (area under/above reference)-and postoperative organ dysfunction Primary endpoints: Emergence delirium incidence (PACU/ITS) based on Nu-DESC scores and CAM-ICU scores; incidence of postoperative acute renal failure (creatinine and urea levels, as well as urine output); intraoperative blood pressure variation\*; intraoperative blood pressure variation rate\*; intraoperative blood pressure integral\* Secondary endpoints: Blood count (hemoglobin and hematocrit values); intraoperative transfusions of blood reserves Addendum from the ethics amendment vote of 25/07/2022 Subproject Delta-Scan started in August 2022: Evaluation of brain function using "Delta Scan" Primary objective: Evaluation of the prognostic significance of Delta Scan measurements in relation to postoperative delirium Secondary objectives: Examination of the delirium-related predictive relevance of individual influencing factors (directly but also indirectly through Delta Scan values) and examination of the effect of Delta Scan measurements on standard delirium screening methods. Study and control group's Inclusion criteria: Age \>= 70 years and major surgery with anesthesia; additional exclusion criterion in the control group: Inclusion in the QV-POD-1 project (receipt of postoperative preventive measures) Addendum from the ethics amendment vote of 25/07/2022 Subproject started in June,18th, 2026: For selected patients who are scheduled to undergo a procedure in June, July, August or September 2026 as part of the QV-POD-2 study, a wristband called CardioWatch 287-2 (manufacturer: Corsano Health B.V., Wilhelmina van Pruisenweg 35, 2595 AN The Hague, The Netherlands, loaned by Medtronic, will be etsablished. For same-day surgery patients, monitoring begins before the operation and continues until discharge from the hospital. For pre-hospitalized patients, measurements can begin at least one day before surgery upon request. The recorded values include blood pressure, heart rate, heart rate variability, respiratory rate, oxygen saturation, body temperature, physical activity, and an electrocardiogram once a day. Subproject started in July, 2026: Economic analysis conducted by Cellogic as a contract research project-selected clinical trial data from the clinical trial database and selected data from the Institute for the Hospital Payment System (InEK), cost unit accounting, and OPS codes will be evaluated for patients form QV-POD-1

Hospital length of stayThe participants are followed up until the end of hospital stay, an expected average of 5 daysHospital length of stay is measured in days
Pain levels 1Up to one yearPain levels 1 are measured with Numeric Rating Scale (NRS). NRS scale's range from 0 to 10. 0: no pain; 1-3: light pain; 4-6: moderate pain; 7-10: severe pain.
Pain levels 2Up to one yearPain levels 2 are measured with Visual Analog Scale (VAS). VAS scale's range from 0 to 10. 0: no pain; 1-3: light pain; 4-6: moderate pain; 7-10: severe pain.
Pain levels 3Up to one yearPain levels 3 are measured with Assessment of pain in dementia (BESD). BESD: The focus of external observation is on the following behavioral patterns: breathing, negative vocalization, facial expression, body language, and comfort in relation to exertional pain. Observed behaviors are assigned a score from 0 to 2. The range of the score is between 0 and 10, with 10 points indicating the most pronounced pain behavior.
Pain levels 4Up to one yearPain levels 4 are measured through the use of a scale based on behaviour items, the Behavioural Pain Scale (BPS). BPS scale's range from 3 to 12; 3: no pain, high number more pain.
Pain levels 5Up to one yearPain levels 5 are measured through the use of a scale based on behaviour items, the Behavioural Pain Scale - non-intubated (BPS-NI). BPS-NI scale's range from 3 to 12; 3: no pain, high number more pain. In the BPS-NI, the BPS item "Adaptation to the Ventilator" has been replaced by "Vocalization." The BPS-NI can be used, for example, to determine pain status in conscious, delirious patients.
Disability 1Up to one yearDisability 1 is measured by Instrumental activities of daily living scale.This scale has 8 categories (ability to use telephone, shopping, food preparation, housekeeping, laundry, mode of transportation, responsibility for own medications, ability to handle finances). Each has different levels of functioning with a score assigned. The patient circles the item that most closely describes its functional level. The lowest score is 0 (better outcome) and the highest is 8 (worse outcome).

Disability 3Up to one yearDisability 3 is measured by hand grip strength test
Anxiety-ScoreUp to one yearFaces Anxiety Scale score
SedationUp to one yearSedation is measured with the Richmond Agitation and Sedation Scale (RASS)
Person's level of consciousnessThe participants are followed up until the end of hospital stay, an expected average of 5 daysThe Glasgow Coma Scale (GCS) is a clinical scale used to reliably measure a person's level of consciousness after a brain injury. The GCS assesses a person based on their ability to perform eye movements, speak, and move their body. These three behaviors make up the three elements of the scale: eye, verbal, and motor. A person's GCS score can range from 3 (completely unresponsive) to 15 (responsive). This score is used to guide immediate medical care after a brain injury (such as a car accident) and also to monitor hospitalized patients and track their level of consciousness. Lower GCS scores are correlated with higher risk of death.
SurvivalUp to one yearSurvival is measured in Patients form QV-POD-2 within 1 year; Survival is measured in patients from QV-POD-1 until 3 months (addendum to the secondary outcome measures from the ethics amendment vote of 28/08/2025) and in patients from QV-POD-2 as Interim analysis of 3-month mortality among QV-POD-2 patients from the recruitment period: July 1, 2023 - December 1, 2025, and then annually in December until the end of the study.
