Background: The population of older adults in long-term care (LTC) is expected to increase considerably in the near future. An understanding of the prevalence of psychiatric disorders in LTC will help in planning mental health services for this population. This study reviews the prevalence of common psychiatric disorders in LTC populations. Methods: We searched electronic databases for studies on the prevalence of major psychiatric disorders in LTC using medical subject headings and key words. We only included studies using validated measures for diagnosing psychiatric disorders or psychiatric symptoms. Our review focused on the following psychiatric disorders: dementia, behavioral and psychological symptoms of dementia (BPSD), major depression, depressive symptoms, bipolar disorder, anxiety disorders, schizophrenia, and alcohol use disorders. We also determined the prevalence of psychiatric disorders in the U.S. LTC population using data from the 2004 National Nursing Home Survey (NNHS). Results: A total of 74 studies examining the prevalence of psychiatric disorders and psychological symptoms in LTC populations were identified including 30 studies on the prevalence of dementia, 9 studies on behavioral symptoms in dementia, and 26 studies on depression. Most studies involved few LTC facilities and were conducted in developed countries. Dementia had a median prevalence (58%) in studies while the prevalence of BPSD was 78% among individuals with dementia. The median prevalence of major depressive disorder was 10% while the median prevalence of depressive symptoms was 29% among LTC residents. There were few studies on other psychiatric disorders. Results from the 2004 NNHS were consistent with those in the published literature. Conclusions: Dementia, depression and anxiety disorders are the most common psychiatric disorders among older adults in LTC. Many psychiatric disorders appear to be more prevalent in LTC settings when compared to those observed in community-dwelling older adults. Policy-makers and clinicians should be aware of the common psychiatric disorders in LTC and further research into effective prevention and treatments are required for this growing population.

Background:Weekly telepsychiatry consultations have been provided since 2002 to six communities in Northwest Ontario. Staff from a single community psychogeriatric outreach service who work within these communities facilitate the referrals.Methods:The program evaluation included (a) a chart review of the last 100 referrals, (b) analysis of patient and staff evaluations, (c) a survey mailed to all physicians in referring communities, and (d) three focus groups of staff working in local community agencies.Results:The mean age at the time of consultation was 76.7 years. Sixty-eight percent of patients were females. The most frequent diagnoses were dementia (54%), depression (28%), and mild cognitive impairment (19%). The most frequent medication recommendations were antidepressants or cholinesterase inhibitors. Two hundred ninety-four patient assessments and case consultations were carried out between 2002 and 2009. Post-session evaluation surveys rated the provision of information, whether objectives were met, and overall usefulness of recommendations. The mean scores for these questions on a 5-point scale were between 4.6 and 4.85. Referring physicians were confident and satisfied with the recommendations made for their patients. All planned to continue to use telepsychiatry as a care option for the future. The focus groups added useful information about challenges and potential barriers to utilizing the program.Conclusions:The program was rated as being highly valued across all modalities of evaluation. Members of the referring team believe that access to a geriatric psychiatrist has broadened the team's knowledge base, its use of assessment tools, and increased their ability to better construct their patients’ treatment plans.

Background Benzodiazepine receptor agonist (BZRA) use disorder among older adults is a relatively common and challenging clinical condition. Method The Canadian Coalition for Seniors’ Mental Health, with financial support from Health Canada, has produced evidencebased guidelines on the prevention, identification, assessment, and management of this form of substance use disorder. Results Inappropriate use of BZRAs should be avoided by considering non-pharmacological approaches to the management of late life insomnia, anxiety, and other common indications for the use of BZRA. Older persons should only be prescribed BZRAs after they are fully informed of alternatives, benefits, and risks associated with their use. Clinicians should have a high index of suspicion for the presence of BZRA use disorders. The full version of these guidelines can be accessed at www.ccsmh.ca Conclusions A person-centred, stepped care approach utilizing gradual dose reductions should be used in the management of BZRA use disorder.

Psychiatric disorders are common among older adults in long-term care (LTC) homes and the LTC population is rapidly growing in many countries. Treatment of psychiatric conditions in this population is challenging given the psychosocial environment and physical frailty of the population. This review highlights some important advances in pharmacological and nonpharmacological interventions in this setting. There is some evidence to support the use of psychosocial interventions for behavioral symptoms, including those utilizing sensory interventions such as aromatherapy and calming music; behavioral management techniques; cognitive stimulation; physical activity; and staff training. There is also some evidence to support the use of psychotherapies such as reminiscence therapy and cognitive behavior therapy for depression. Recent literature on the pharmacological management of behavioral symptoms of dementia have included studies of the antipsychotic aripiprazole, prazosin, and medication-discontinuation trials along with two negative studies involving melatonin and oxcarbazepine. The literature on psychosocial interventions for behavioral symptoms associated with dementia has been criticized for lack of vigor, but there is growing evidence from studies with improved methodology that these interventions may confer significant benefits, although the effect sizes are often small or moderate. More well designed trials of pharmacological therapies in the LTC population are also necessary.
