Aim of the study is an examination whether a modified perioperative pain management system, that integrates the 2017 European Society of Anaesthesiology (ESA) guidelines for treatment of postoperative Delirium, can improve patient's wellbeing in comparison to the current certified standard management.
Aim of the study is to evaluate whether the integration of the 2017 ESA guidelines for treatment of postoperative Delirium in a pain management, can improve patient's wellbeing in comparison to the current certified standard management. Adherence to the modified management includes minimizing nil per os time, renouncing benzodiazepines, 1.8 ltr crystalloid infusion per day, simplified standard medication option and postoperative 12µg/h Fentanyl TTS for 72h (for wound pain).

Patients will be treated perioperatively with a new pain management, that has been modified to integrate the 2017 ESA guidelines on prevention/treatment of postoperative delirium. Moreover patients will be administered a 12µg/h Fentanyl TTS in the ER or PACU. The ER TTS will only be administered if the patients still has mild to intense pain after initial intravenous (i.v.) treatment as well as reposition of the fractured hip. Further aspects of the modified management are: avoiding benzodiazepines, allowing oral fluids up to 2 hours before surgery, intraoperative monitoring of anaesthesia depth and at least 1,8 ltr crystalloid infusion per day.

Patient's wellbeing in the awakening room
Wellbeing assessed with the "Anaesthesiological Questionnaire" (ANP) which is a self-rating method for the assessment of postoperative complaints and patient wellbeing. The rating scales from 0 to 3, with 0="none" and 3="strongly". Higher wellbeing values represent a better outcome.
Time frame: 1 year
Complication rate (delirium, periprosthetic fractures, wound infections etc)
All complications occuring during hospital stay will be statistically evaluated for differences between the two study groups.
Time frame: Through study completion, an average of 10 days
Efficacy of the pain management in reducing pain
Pain will be assessed with the (verbal) Numerical Rating Scale (NRS) and statistically evaluated for differences between the two study groups. NRS scales from 1 to 10, with 1 describing the lowest pain score and 10 the highest pain score. Lower NRS describes a better outcome.
Time frame: Through study completion, an average of 10 days
Interview assessed identification of selfreported parameters influencing patient-wellbeing
Feedback interviews with the patients giving them the opportunity to express what influenced their wellbeing the most.
Time frame: Through study completion, an average of 72 hours postoperatively
