DELIVER (DELiberative ImproVEment of oRal care quality) is a multinational project funded under the EU’s Horizon Europe program; we aim to develop a blueprint model for improving the quality of oral health care for everyone: the DELIVER Quality Improvement Model. We are a team of partners from Denmark, England, Germany, Malta, the Netherlands, Portugal, and Sweden who will use a mixed-methods research approach to create a synergistic problem-solving ecosystem to convert deliberative dialogues into meaningful support for improving the quality of oral health care. Together with citizens/patients, providers, payers, and policymakers, new quality improvement (QI) approaches will be codeveloped and coproduced in 3 phases (over 4 y): phase 1 involves defining quality of oral health care, situational analysis of the status quo of QI, and consenting of core quality indicators for a Europe-wide monitoring framework. Phase 2 involves in-depth analysis of select QI approaches: 1) QI in dental practices based on patient-reported outcome and experience measures (PROMs/PREMs), 2) community-based QI for vulnerable groups, and 3) quality-oriented commissioning of oral health services. In addition, the regulatory determinants of oral health care QI will be scrutinized. In phase 3, the knowledge gained from phases 1 and 2 will be used to develop the DELIVER Quality Toolkit, a resource containing manuals and digital tools to support context-specific implementation of oral health care QI. DELIVER is anticipated to contribute to positive changes in oral health systems. Knowledge Transfer Statement: The EU DELIVER project aims to enhance the quality of oral health care through codevelopment and coproduction of solutions together with citizens/patients, providers, and policymakers. The unique multicountry nature of the project will facilitate fast-track prototype development and testing of innovative QI approaches in select countries. Reflective learning regarding the transferability of findings between different countries and settings offers unique opportunities to drive progress toward context-specific implementation of innovative oral health care QI approaches. The collective knowledge gained from the 7 European countries involved in DELIVER can also generate knowhow for improving the quality of oral health care in other countries around the globe.
