The project aims to improve patient safety, reduce barriers to the implementation of current guideline recommendations, reduce workload in clinics, increase efficiency in work processes and close gaps in care. Subprojects regarding delirium are implementes as well.
Postoperative delirium (POD) is the most common post-operative complication in the 70+ age group, affecting approximately fifteen percent of elderly patients. POD is characterized by impaired attention, awareness, and cognitive function. Both patients and their families are severely affected by the effects of this condition. While symptoms of POD occur during hospitalization, they have a critical impact on post-hospitalization quality of life, dependency on long-term care, and life expectancy. The overarching goal of the Digi-POD project consortium is to develop a digital decision support system that makes current evidence-based guideline recommendations for POD machine-readable and allows automated, real-time validation against clinical data. Sub-projects such as a point prevalence analysis on the incidence of delirium on 2 days at the Charité and a staff survey conducted by Aktionsbündnis Patientensicherheit e.V. in all study centers accompany this study. Further substudies initiated by Charité Universitätsmedizin Berlin: Two substudies (one feasibility study and one acceptance study) will be conducted using the prototype of the Clinical Brain Protection (CBP) application in Digi-POD patients at Charité. Interviews and a review of project documentation to analyze obstacles and solution strategies for implementing data security/information security will be organized by Fraunhofer Fokus. The results will be incorporated into the Data Security project report.

Guideline adherence
Guideline adherence: proportion of guideline recommendations fulfilled per patient in the first five postoperative days. The guideline adherence rate up to postoperative day 5 (or earlier if the patient has already been discharged) is calculated as a simple division: Number of recommendations fulfilled by number of all recommendations (N=6).
