Modified Oral Health Assessment Tool (M-OHAT) for residential aged care: a co-design protocol

Background: Older adults in residential aged care facilities (RACFs) experience disproportionate levels of poor oral health relative to other groups in the general population, affecting their physical and mental wellbeing. The Oral Health Assessment Tool (OHAT) is a validated and widely used dental assessment tool; however, recent systematic reviews have identified shortcomings with respect to its measurement properties. Objective: The objective of this protocol is to provide a detailed overview of a multidisciplinary qualitative study that aims to (a) co-design and develop a modified OHAT for RACFs and (b) inform the development of an OHAT training package and implementation strategies. Methods: This study will utilize a co-design methodology with aged care residents, caregivers, staff members, and health professionals. The co-design workshops will: (1) investigate the barriers to and enablers of optimal oral healthcare in RACFs; and (2) co-design a modified version of the Oral Health Assessment Tool and a referral to treatment pathway that is appropriate for use in RACFs. The co-design workshops will facilitate group discussion and involve interactive activities using, for example, mind mapping and Sticky Notes. Qualitative data (transcripts and artefacts from co-design activities) will be analyzed in NVivo using an inductive codebook thematic analysis, specifically a template analysis. Conclusion: The findings of this study will inform a modified OHAT (M-OHAT), as well as future study phases regarding training and implementation strategies. It is expected that the M-OHAT will have enhanced usability and relevance to RACFs, facilitating the identification of poor oral health and timely referral to dental treatment.
