Intra- and interobserver reliability of nurses and dentists in the assessment and screening of oral conditions of institutionalized older adults

Abstract Introduction older persons in Long-Term Care (LTC) facilities have functional impairments and a higher disease prevalence. Nurses’ comprehensive assessment of older persons’ health is highlighted, including using tools for screening dental treatment needs. Objective to report the intra- and inter-observer reliability of older adults’ oral health assessment in LTC facilities by video. Material and method descriptive study, in three LTC facilities, in the Florianópolis region, Southern Brazil. Data were collected according to Oral Health Assessment Tool (OHAT), which presents 8 categories (“lips, tongue, gums/tissues, saliva, natural teeth, dentures, dental hygiene, and toothache”), and the scores 0=healthy, 1=presence of changes (could be a need for care), 2=unhealthy (need for dental service); final score from 0 to 16. In each LTC facility, a Nurse assessed oral conditions and made a video of each older adult using a smartphone. The dentist performed the oral health assessment through the videos. Estimated Kappa test, p<0.05. Result the sample was 34 older adults, 71% were female. Interobserver reliability between Nurses 1 and 2 and Dentist for “lips” and “natural teeth” was classified as poor and excellent/very good for toothache and denture conditions. The nurse’s intraobserver reliability was classified as weak for the “natural teeth” assessment. Conclusion the OHAT showed reliability for assessing denture conditions and pain. However, nurses’ training for recognizing oral conditions that require dental care is suggested, as well as the management of this action by the dentist and LTC facilities.
