BackgroundVerbal and physical aggressive behaviours are among the most disturbing and distressing behaviours displayed by older patients in long-term care facilities. Aggressive behaviour (AB) is often the reason for using physical or chemical restraints with nursing home residents and is a major concern for caregivers. AB is associated with increased health care costs due to staff turnover and absenteeism.MethodsThe goals of this secondary analysis of a cross-sectional study are to determine the prevalence of verbal and physical aggressive behaviours and to identify associated factors among older adults in long-term care facilities in the Quebec City area (n = 2 332).ResultsThe same percentage of older adults displayed physical aggressive behaviour (21.2%) or verbal aggressive behaviour (21.5%), whereas 11.2% displayed both types of aggressive behaviour. Factors associated with aggressive behaviour (both verbal and physical) were male gender, neuroleptic drug use, mild and severe cognitive impairment, insomnia, psychological distress, and physical restraints. Factors associated with physical aggressive behaviour were older age, male gender, neuroleptic drug use, mild or severe cognitive impairment, insomnia and psychological distress. Finally, factors associated with verbal aggressive behaviour were benzodiazepine and neuroleptic drug use, functional dependency, mild or severe cognitive impairment and insomnia.ConclusionCognitive impairment severity is the most significant predisposing factor for aggressive behaviour among older adults in long-term care facilities in the Quebec City area. Physical and chemical restraints were also significantly associated with AB. Based on these results, we suggest that caregivers should provide care to older adults with AB using approaches such as the progressively lowered stress threshold model and reactance theory which stress the importance of paying attention to the severity of cognitive impairment and avoiding the use of chemical or physical restraints.

Aims and objectives.  The objectives of this study were to determine the prevalence of falls with minor and major injuries and identify their risk factors. Background.  Falls among residents of long-term care facilities (LTCF) constitute a significant health issue. Design.  This is a secondary analysis of a cross-sectional study carried out among older people (n = 2332). Methods.  This is a descriptive study focusing on the secondary analysis of a cross-sectional study carried out with a group of older people (n = 2332) in 28 LTCF in Quebec City, Canada. Research assistants collected original data for each resident from two sources: structured simultaneous interviews with two nurses per unit from each of the homes and a review of the residents' medical files. Results.  7.2% of subjects had a fall leading to minor injuries and 10.1% a fall leading to major injuries. Risk factors associated with fall-related minor injury are young age, male gender and cognitive impairment. Factors associated with fall-related major injury were functional autonomy and length of stay. In further statistical analysis, controlling for functional autonomy, disruptive behaviours and neuroleptic use were found associated with fall-related major injury. Conclusions.  This study demonstrates that the factors associated with fall-related minor injury are different from those associated with fall-related major injury. Relevance to clinical practice.  This study suggests that nurses working with LTCF residents who are concerned about the prevention of fall-related major injury, may contribute to a reduction in such falls through optimal management of behavioural problems and neuroleptic use.
