Care-resistant behaviour during oral examination in Dutch nursing home residents with dementia.

Objective: To assess the occurrence and associations of verbal and non-verbal care-resistant behaviour (CRB) during oral examination by a dental hygienist in nursing home residents with dementia.

Background: CRB is a barrier to providing professional oral care and daily oral hygiene care. Understanding the predictors of CRB might help care professionals in learning to anticipate this behaviour.

Methods: In this multicentre cross-sectional study signs of verbal and non-verbal CRB were reported during the oral examination. Data collection occurred in the psychogeriatrics wards of 14 different nursing homes in the Netherlands (N = 367).

Results: A total of 367 residents were included. CRB was evident in 82 residents (22.3%), of whom 45 (55%) showed verbal and 37 (45%) non-verbal CRB. Associated with CRB were age >85 years, duration of residential stay longer than 2 years, and having Korsakov dementia. Other factors associated with CRB were duration of residential stay (categories ">2 and ≤4 years" or ">4 years") and having a natural dentition (P = .043-.005, OR = 1.20-1.33, 95% CI = 1.00-8.48). Significant associations for verbal and non-verbal CRB were age between 76 and 85 years, vascular dementia and Korsakov dementia (P = .031-.006, OR = .020-1.49, 95% CI = 0.43-2.15).

Conclusion: The occurrence of CRB was 22.3% and was associated with older age and longer duration of residential stay, Vascular and Korsakov dementia and natural dentition.
