Development and validation of a patient-based outcome measure for endodontic treatment

Background: in 1970’s the seminal work of Cohen and Jago initiated an interest in the measurement of health related quality of life measures in dentistry. Clinical measures to assess oral health from the dentist’s perspective do not necessarily measure well-being. The patient reported outcome measures are an important tool to measure and improve the quality of care. Aim: The aim of the project was to create and validate a brief instrument for measuring patient-based oral health outcomes associated with endodontic care. Method: Based on the literature review of the currently used core oral health outcome measures, items from established instruments were selected to generate pool of items for the new measure. All subjects attending primary dental care at a local dental teaching hospital specifically for endodontic treatment provided by undergraduates self-completed this outcome measure prior to, immediately following care and at one month follow-up visit. Using multicollinearity, factor analysis, regression modelling and an expert based approach items were identified for a brief instrument. The newly developed brief instrument was tested for its reliability, validity and responsiveness on patients attending for endodontic treatment in the same clinical setting using the self-completed questionnaire at the baseline and after completion of the treatment. Results: 46 Items from OHIP-49 (Oral Health Impact Profile) and 12 items from GOHAI (General Oral Health Assessment Index) were used as the basis for development of an endodontic outcome measure. Multicollinearity, factor analysis and regression analysis of the long-form of the instrument (58 items) identified 15 significant items associated with improved oral health.
