Usage and Scientific Properties of the ADVOCATE Oral Health Care Measures.

Background: Feedback information about the quality of oral health care is important for reflective learning by oral health care professionals and the wider health system. To this end, a list of 48 topics describing oral health and oral health care was recently agreed as part of the EU H2020 ADVOCATE project. Objective: This article reports on the formulation of measures based on the ADVOCATE topics and provides information on usage, reporting, validity, and reliability of the measures. Methods: The AIRE instrument was used to guide the methodological approach adopted. The appropriateness of the measures was tested among 39 general dental practitioners (GDPs) in Denmark, Germany, and the Netherlands. Data were collected from a convenience sample of patients via a questionnaire deployed in an online application in their practice. Feasibility, acceptability, and usefulness of the measures were evaluated through focus group interviews with GDPs. Face validity and test-retest reliability of the measures were assessed. Results: For 46 of the 48 topics, a measure could be defined by constructing a definition and a numerator and denominator. Data collection for all 46 measures was feasible and acceptable for patients using the online questionnaire. The practicalities of using claims data for the purpose of giving feedback to individual and groups of GDPs proved to be challenging in terms of timely access of such data, the granularity of the data, and matching the content of the data with the consented items on quality of oral health care. Face validity was considered appropriate, as the patients found the questionnaire easy to understand. Test-retest reliability was found to be acceptable for 36 of 46 measures. Conclusion: The broad range of the ADVOCATE oral health care measures could make a useful contribution to a more transparent, evidence-based, and patient-centered oral health care system. Knowledge Transfer Statement: This study shows the usage, reliability, and validity of 46 oral health care measures. The measures, which include patient experience and health behaviors, were found to be useful to stimulate discussions about clinical practice. The measures can provide essential information for quality improvement strategies and useful and relevant feedback information for GDPs.
