In 2017, the Federal Joint Committee (Gemeinsamer Bundesausschuss) introduced a \u2018quality contract\u2019 (QC) as a new instrument to improve healthcare in Germany. One of the four areas for improvement of in-patient care is the \u2018Prevention of POD in the care of elderly patients\u2019 (QC-POD), as a means to reduce the risk of developing POD and its complications.<\/jats:p><jats:p>The Institute for Quality Assurance and Transparency in Health Care identified gaps in the in-patient care of elderly patients related to the prevention, screening and treatment of POD, as required by consensus-based and evidence-based delirium guidelines. This paper introduces the QC-POD protocol, which aims to implement these guidelines into the clinical routine. There is an urgent need for well-structured, standardised and interdisciplinary pathways that enable the reliable screening and treatment of POD. Along with effective preventive measures, these concepts have a considerable potential to improve the care of elderly patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and analysis<\/jats:title><jats:p>The QC-POD study is a non-randomised, pre\u2013post, monocentric, prospective trial with an interventional concept following a baseline control period. The QC-POD trial was initiated on 1 April 2020 between Charit\u00e9-Universit\u00e4tsmedizin Berlin and the German health insurance company BARMER and will end on 30 June 2023. Inclusion criteria: patients 70 years of age or older that are scheduled for a surgical procedure requiring anaesthesia and insurance with the QC partner (BARMER). Exclusion criteria included patients with a language barrier, moribund patients and those unwilling or unable to provide informed consent. The QC-POD protocol provides perioperative intervention at least two times per day, with delirium screening and non-pharmacological preventive measures.<\/jats:p><\/jats:sec><jats:sec><jats:title>Ethics and dissemination<\/jats:title><jats:p>This protocol was approved by the ethics committee of the Charit\u00e9-Universit\u00e4tsmedizin, Berlin, Germany (EA1\/054\/20).
