Self-destructive behaviors in nursing home residents

Factors Associated With Hospital Presentation of Self-Harm Among Older Canadians in Long-Term Care: A 12-Year Cohort Study

OBJECTIVES

This study aimed to examine the incidence of, and factors associated with, hospital presentation for self-harm among older Canadians in long-term care (LTC).

DESIGN

Retrospective cohort study.

SETTING AND PARTICIPANTS

The LTC data were collected using Resident Assessment Instrument-Minimum Data Set (RAI-MDS) and Resident Assessment Instrument-Home Care (RAI-HC), and linked to the Discharge Abstract Database (DAD) with hospital records of self-harm diagnosis. Adults aged 60+ at first assessment between April 1, 2003, and March 31, 2015, were included.

METHODS

Adjusted hazard ratios (HRs) of self-harm for potentially relevant factors, including demographic, clinical, and psychosocial characteristics, were calculated using Fine & Gray competing risk models.

RESULTS

Records were collated of 465,870 people in long-term care facilities (LTCF), and 773,855 people receiving home care (HC). Self-harm incidence per 100,000 person-years was 20.76 [95% confidence interval (CI) 20.31-25.40] for LTCF and 46.64 (44.24-49.12) for HC. In LTCF, the strongest risks were younger age (60-74 years vs 90+: HR, 6.00; 95% CI, 3.24-11.12), psychiatric disorders (bipolar disorder: 3.46; 2.32-5.16; schizophrenia: 2.31; 1.47-3.62; depression: 2.29; 1.80-2.92), daily severe pain (2.01; 1.30-3.11), and daily tobacco consumption (1.78; 1.29-2.45). For those receiving HC, the strongest risk factors were younger age (60-74 years vs 90+: 2.54; 1.97-3.28), psychiatric disorders (2.20; 1.93-2.50), daily tobacco consumption (2.08; 1.81-2.39), and frequent falls (1.98; 1.46-2.68). All model interactions between setting and factors were significant.

CONCLUSIONS AND IMPLICATIONS

There was lower incidence of hospital presentation for self-harm for LTCF residents than HC recipients. We found sizable risks of self-harm associated with several modifiable risk factors, some of which can be directly addressed by better treatment and care (psychiatric disorders and pain), whereas others require through more complex interventions that target underlying factors and causes (tobacco and falls). The findings highlight a need for setting- and risk-specific prevention strategies to address self-harm in the older populations.

A Psychometric Assessment of the Suicidal Behaviors Questionnaire (SBQ-5) and Geriatric Suicide Ideation Scale-Screen (GSIS-screen) in Middle-Aged and Older Men

Objectives. To investigate the psychometric properties of the five-item Suicidal Behaviors Questionnaire (SBQ-5) and the Geriatric Suicide Ideation Scale-Screen (GSIS-Screen, submitted) among community-residing middle-aged and older men.Methods. The SBQ-5 and GSIS-Screen were administered to 93 men, 55 years or older, who participated in an eligibility assessment (Time 1) for an upstream psychological intervention study to prevent the onset of suicide ideation among men struggling to transition to retirement. Eligible participants later completed the full GSIS and measures of depression and hopelessness at a pre-group assessment (Time 2).Results. The SBQ-5 was positively associated with the GSIS-Screen at the eligibility assessment. Internal consistency for both measures was low but acceptable. Time 1 scores on both screens predicted suicide ideation at Time 2, controlling for the intervening time lag and for baseline cognitive and physical functioning. Only the GSIS-Screen uniquely predicted future depression and hopelessness ratings.Conclusions. The SBQ-5 and the GSIS-Screen have acceptable psychometric properties among middle-aged and older community-residing men; the GSIS-Screen is more closely associated with later-life suicide risk factors.Clinical Implications. Brief screening tools may be of use in effectively identifying suicide ideation in community-residing middle-aged and older men.

Self-harm in the very old one year later: has anything changed?

OBJECTIVES

To follow-up a cohort of older people who self-harmed, their carer, and general practitioner (GP) and examine their reflections on the self-harm, care experiences, and outcomes.

DESIGN

Qualitative in-depth interviews.

SETTING

Two teaching hospitals and associated community services.

PARTICIPANTS

Twelve-month follow-up of participants aged 80 or older who self-harmed, their nominated carers, and GPs.

MEASUREMENTS

A geriatric psychiatrist gathered data through patient and carer interviews using a narrative inquiry approach and from medical records. Interviews were audio recorded and transcribed. N-VIVO facilitated data organization for thematic analysis. Questionnaires sent to the patient's GP examined their perspectives and aspects of care relating to the self-harm.

RESULTS

Nineteen patients (63% baseline sample), 29 carers (90.6%), and 11 GPs (36.7%) were available at follow-up. Themes emerging from patients were "denial and secrets;" "endless suffering;" "more invalidation;" "being heard;" and "miserable in care." Themes from carer interviews were "denial and secrets;" "patient's persistent wish to die;" "abandonment by clinicians;" "unending burden for the carer;" and "distress regarding placement." General practitioner themes were "the problem is fixed;" "the troops have arrived;" and "I understand."

CONCLUSIONS

Factors contributing to self-harm persisted at follow-up. Positive and negative responses were identified in the older person's system, highlighting areas for potential intervention. A conceptual framework for understanding self-harm in the very old was derived that emphasized the importance of understanding individual needs, the interpersonal context of the older person, and carer burden. Interventions should improve communication, facilitate shared understanding of perspectives, and provide support at all levels.

Study of scientific publications (2002-2017) on suicidal ideation, suicide attempts and self-neglect of elderly people hospitalized in Long-Term Care Establishments

This is a study on scientific work on the ideation, suicide attempt and self-neglect of elderly residents in LTCEs from 2002 to 2017. Documents were retrieved from the following sources: BVS/SP, SciELO, Scopus, PubMed and Web of Science, with the following descriptors: suicide attempt, suicidal ideation, self-neglect, elderly, long-term care establishment, and their correspondents in Portuguese, Spanish and French. Twenty-six papers on the subject were found. There is a consensus among the authors, whose texts are analyzed here, concerning the factors that lead the elderly to suicidal behavior: depression, illness and pain, complicated and traumatic mourning, anxiety and despair after recovery from depressive episode, poor living conditions, death of close relatives, friends, family conflicts, family history of self-inflicted events. The protection factors found are religiosity, optimistic lifestyle, satisfaction with life and investment in the autonomy and power of relationships and communication and monitored drug therapy for mental disorders such as depression.

Carer insights into self-harm in the very old: A qualitative study

OBJECTIVE

To examine the insights of carers to better understand self-harm in their older relatives.

METHODS

An in-depth interview was conducted with the nominated relative/friend (carer) of a person over 80 who had self-harmed within the last month. Carer interpretation and experience of the self-harm and clinical care were explored qualitatively. Audio recordings were transcribed and the content thematically analyzed using N-VIVO.

RESULTS

Thirty-two carers of 30 older people who self-harmed were interviewed. Physical, social, and psychological issues were identified as contributory to self-harm. Themes relating to the perceived barriers to seeking help included "they can't communicate," "suicide and secrets," and "invalidation." Themes for the intent of self-harm were "attention seeking" and "wanting to die." Themes which emerged for consequences of self-harm for carers were "anger," "guilt and self-blame," and "it made us ill." Themes for solutions to address the underlying factors leading to self-harm were "more practical support and structure," "improving communication," "removing means of self-harm," "advance care directives as a solution for suffering," and "ignoring self-harm." Clinical care themes were "shared shame and stigma," "safety and supervision vs being locked up," "clinicians dismissing the carer," and "relief and support."

CONCLUSIONS

Validation of carer perspectives and understanding family dynamics may improve communication at various system levels and inform interventions for older persons, concurrently support families, and potentially reduce risk of repeat self-harm. Good care must be holistic, be person-centred, and relieve carer burden. A shared understanding and psychotherapeutic approaches to management of self-harm in late life should be considered.

The survival and characteristics of older people with and without dementia who are hospitalised following intentional self-harm

OBJECTIVE

Characteristics of older people with and without dementia who are hospitalised following self-harm remains largely unexplored. This research compares the characteristics of older people with and without dementia who self-harm, compares associations of mental health-related diagnoses with those hospitalised for a self-harm and a non-self-harm injury and examines mortality by injury intent.

METHOD

A population-based study of individuals aged 50+ years with and without dementia admitted to hospital for a self-harm injury (and those with other injuries) using linked hospital admission and mortality records during 2003-2012 in New South Wales (NSW), Australia. Health outcomes, including hospital length of stay (LOS), 28-day readmission and 30-day and 12-month mortality were examined by dementia status.

RESULTS

There were 427 hospitalisations of individuals with dementia and 11,684 hospitalisations of individuals without dementia following self-harm. The hospitalisation rate for self-harm for individuals with dementia aged 60+ years was double the rate for individuals without dementia (72.2 and 37.5 per 100,000). For both older people with and without dementia, those who self-harmed were more likely to have co-existent mental health and alcohol use disorders than individuals who had a non-self-harm injury. Individuals with dementia had higher 12-month mortality rates, 28-day readmission and longer LOS than individuals without dementia.

CONCLUSION

Dementia is associated with an increased risk of hospitalisation for self-harm in older people and worse outcomes. The high rate of coexistent mental health conditions suggests that interventions which reduce behavioural and psychological symptoms of dementia might reduce self-harm in people with dementia.

Suicide and assisted dying in dementia: what we know and what we need to know. A narrative literature review

BACKGROUND

Evidence-based data on prevalence and risk factors of suicidal intentions and behavior in dementia are as scarce as the data on assisted dying. The present literature review aimed on summarizing the current knowledge and provides a critical discussion of the results.

METHODS

A systematic narrative literature review was performed using Medline, Cochrane Library, EMBASE, PSYNDEX, PSYCINFO, Sowiport, and Social Sciences Citation Index literature.

RESULTS

Dementia as a whole does not appear to be a risk factor for suicide completion. Nonetheless some subgroups of patients with dementia apparently have an increased risk for suicidal behavior, such as patients with psychiatric comorbidities (particularly depression) and of younger age. Furthermore, a recent diagnosis of dementia, semantic dementia, and previous suicide attempts most probably elevate the risk for suicidal intentions and behavior. The impact of other potential risk factors, such as patient's cognitive impairment profile, behavioral disturbances, social isolation, or a biomarker based presymptomatic diagnosis has not yet been investigated. Assisted dying in dementia is rare but numbers seem to increase in regions where it is legally permitted.

CONCLUSION

Most studies that had investigated the prevalence and risk factors for suicide in dementia had significant methodological limitations. Large prospective studies need to be conducted in order to evaluate risk factors for suicide and assisted suicide in patients with dementia and persons with very early or presymptomatic diagnoses of dementia. In clinical practice, known risk factors for suicide should be assessed in a standardized way so that appropriate action can be taken when necessary.

Suicidal behavior and assisted suicide in dementia

BACKGROUND

Concerns about suicide risk in people with dementia have been increasing in recent years along with a discourse about rational suicide and assisted suicide.

METHODS

A systematic narrative literature review of suicidal behavior and assisted suicide in persons with dementia.

RESULTS

Most studies that have examined the spectrum of suicidal ideation, attempted suicide and suicide in dementia have methodological limitations but the overall suicide risk does not appear to be increased. When suicidal behavior does occur, common themes include the presence of psychiatric comorbidity, mainly depression; occurrence early in the dementia course with preserved insight and capacity; and an increased risk in younger people. The emerging discourse on rational and assisted suicide has been spurred by early and pre-symptomatic diagnosis and poses a number of ethical challenges for clinicians including the role of proxy decision-makers.

CONCLUSIONS

Although dementia might not confer a significant overall risk for suicidal behavior, clinicians still need to consider the potential for suicide in vulnerable individuals particularly early in the dementia course.

Suicide risk in long-term care facilities: a systematic review

OBJECTIVE

Suicide risk is highest in later life; however, little is known about the risk of suicide among older adults in long-term care facilities (e.g., nursing homes and assisted living facilities). The goal of this paper is to review and synthesize the descriptive and analytic epidemiology of suicide in long-term care settings over the past 25 years.

METHODS

Four databases (PubMed, CINAHL Plus, Web of Knowledge, and EBSCOHost Academic Search Complete) were searched for empirical studies of suicide risk in nursing homes, assisted living, and other residential facilities from 1985 to 2013. Of the 4073 unique research articles identified, 37 were selected for inclusion in this review.

RESULTS

Of the included reports, 21 were cross-sectional, 8 cohort, 3 qualitative, and 5 intervention studies. Most studies indicate that suicidal thoughts (active and passive) are common among residents (prevalence in the past month: 5-33%), although completed suicide is rare. Correlates of suicidal thoughts among long-term care residents include depression, social isolation, loneliness, and functional decline. Most studies examined only individual-level correlates of suicide, although there is suggestive evidence that organizational characteristics (e.g., bed size and staffing) may also be relevant.

CONCLUSIONS

Existing research on suicide risk in long-term care facilities is limited but suggests that this is an important issue for clinicians and medical directors to be aware of and address. Research is needed on suicide risk in assisted living and other non-nursing home residential settings, as well as the potential role of organizational characteristics on emotional well-being for residents.

Suicide in elderly South Tyroleans in various residential settings at the time of death: a psychological autopsy study

BACKGROUND

Completed suicide is more frequent among older adults than any other age group. Data on suicide in nursing homes and other residential facilities are inconsistent. This work aims to describe the characteristics of elderly suicide victims in different residential settings compared to young suicide victims.

METHODS

Data on people who died by suicide in the South Tyrol (Alto Adige) region of Italy between 2000 and 2009 were gathered from the local Provincial Mortality Register. Further detailed information was collected via questionnaires to mental health departments and psychological services, family physicians and relatives of the deceased.

RESULTS

A total of 525 cases of suicide were recorded, with a linearly decreasing trend during the study period. About one-third of the suicides occurred in those aged 60 years and over. Suicide in the elderly was associated with low education level (odds ratio (OR) = 7.1, P < 0.001), living in a one-person household (OR = 2.4, P < 0.01), not having economic troubles (OR = 6.1, P < 0.01), having seen a doctor in the past month (OR = 2.4, P < 0.01) and living in a residential facility (OR = 2.6, P < 0.05). Twenty-four (17.9%) suicide victims aged 60 years and over were in a residential facility/hospital at the time of the death. They were more likely to be women, not married, and to die by jumping from a height.

CONCLUSIONS

The suicide risk should be carefully assessed in the elderly who live alone or are institutionalized or hospitalized. Efforts are warranted to reduce seniors' access to high places in hospitals and facilities.

Comparing the neuropsychiatric inventory and the revised memory and behavior problems checklist for associations with caregiver burden and depressive symptoms

BACKGROUND

Few empirical studies compare the ability of prominent measures of behavioral and psychological symptoms of dementia (BPSD) to explain key caregiver outcomes. We compared the respective abilities of the Neuropsychiatric Inventory (NPI) and the Revised Memory and Behavior Problems Checklist (RMBPC) to detect associations between BPSD and caregiver depressive symptoms. Our results may facilitate measurement decisions for researchers and clinicians.

METHODS

The NPI and the RMBPC, which measure BPSD frequency and corresponding caregiver appraisals, were administered to 164 caregivers of persons with dementia to compare the measures' ability to explain caregiver depressive symptoms. Depressive symptoms were measured using the Geriatric Depression Scale (GDS), and caregiver burden was measured (using the Zarit Burden Interview) as a mediator between BPSD frequency/appraisal and caregiver depressive symptoms. Path analysis using Mplus facilitated the comparison between the RMBPC and the NPI.

RESULTS

Significant indirect associations were present when NPI frequency, NPI appraisal, RMBPC frequency, and RMBPC appraisal were modeled separately with burden and depressive symptoms, although indirect relationships are not associated with increases in R(2). Only RMBPC appraisal produced both a significant direct association with depressive symptoms and a significant increase in R(2) when modeled separately (β = 0.24, p < 0.01; ΔR(2) = 0.04, p < 0.05). When all independent variables were modeled together, only RMBPC appraisal demonstrated significant direct (β = 0.23, p < 0.01) and indirect associations.

CONCLUSION

The RMBPC might be more suitable than the NPI in studies measuring BPSD to explain key caregiver outcomes such as depressive symptoms.

Prevalence and correlates of suicidal thought and self-destructive behavior among an elderly hospital population in Iran

BACKGROUND

Few studies have examined suicidal ideation and behavior in hospitalized physically ill elderly patients, a group potentially at high risk. Our aim was to investigate the prevalence and risk factors for suicide ideation, and direct and indirect self-destructive behaviors among a sample of elderly inpatients.

METHODS

A cross-sectional study was conducted in 2009; 650 inpatients aged 60 years and over were screened from various medical services in teaching hospitals affiliated to Shiraz University of Medical Sciences in Iran. Suicidal ideation and behavior were measured with the Beck Scale for Suicidal Ideation (BSSI) and the Harmful Behavior Scale (HBS). Depression was measured with the Geriatric Depression Scale (GDS), medical burden with the geriatric version of the Cumulative Illness Rating Scale (CIRS-G), life events with the Paykel Life Event Scale, and social support with the Perceived Social Support Scale.

RESULT

Of the 650 patients screened with a mean age of 70.5 years (SD ± 7.5), 570 met inclusion criteria and of these 123 (21.6%) reported suicidal ideation on the BSSI and 80 (14.4%) had at least one self-destructive behavior included in the HBS. There was a significant correlation between suicide ideation and harmful behaviors (r = 0.503, p = 0.001). In a regression analysis, depressive symptoms, increased burden of medical conditions, marital status, history of substance use, history of traumatic life events, lack of perceived social support, and poor education were associated with both suicide ideation and harmful behavior. From demographic variables, living without a spouse and unemployment were predictors of suicidal ideation and behavior.

CONCLUSION

Hospitalized, physically ill elderly patients have high rates of suicidal ideation and self-destructive behavior and these vary according to psychosocial and clinical factors. The general hospital is therefore a potential site for the recognition of suicidal individuals and implementation of proximal suicide prevention strategies.

Self-injurious behavior in the nursing home setting

BACKGROUND

Self-injurious behavior (SIB) in older adults is defined as harm inflicted on oneself without conscious suicidal intent. SIB as a separate entity distinct from suicidal intent is poorly understood. However, it is of great concern to the patients' families and caregivers and it poses serious clinical challenges for clinicians.

METHODS

We searched the database of PubMed, Ovid Medline, and ScienceDirect for reports published between 1970 and 2009 using combination of the following keywords: "self-injurious behavior", "self-destructive behavior", "self-mutilating behavior", "older adults", "geriatric population", and "nursing homes". The term "self-harm behavior" which also appears in the literature is broader in scope than "self-injurious behavior". It encompasses high suicide intent and failed suicide attempts; therefore, we excluded this term in order to focus purely on "self-injurious behavior". Our search yielded 10 publications concerning SIB in older adults, four of which included studies investigating SIB in nursing homes.

RESULTS

Clinical studies of SIB in older adult nursing home residents are sparse. This limited literature suggests that SIB is a prevalent phenomenon and is reported to be as high as 14% in one study of nursing home subjects aged 65 and older. It is reported to be strongly associated with dementia and a risk of accidental death. It has been suggested that SIB among demented patients occurs in the context of poor impulse control and physical isolation.

CONCLUSION

SIB is likely a common phenomenon in older adult nursing home residents. There is little evidence-based treatment guidance for SIB in older population.

Death ideas, suicidal thoughts, and plans among nursing home residents

Recent studies have shown that suicides are at least as frequent among Nursing Home (NH) residents as they are among older people in the general population. The objective of the present study was to evaluate the prevalence of death- and/or suicidal feelings, thoughts, and plans and any attempted suicides in a random, unselected sample (N=288) of individuals aged 65-years-and-over, living in NHs located in the Veneto Region (the Italian North-East). One hundred seventy-two participants were surveyed with a response rate of 59.7%. Five sample questions were asked to investigate the presence of death- and suicidal thoughts, plans and behaviors in different time periods. Among the NH residents, 30.8% admitted having had death or suicidal thoughts or plans during the month prior to the interview. The oldest-old residents (85+y) more frequently reported death-suicide ideation. This high frequency of death and/or suicidal feelings and thoughts among older NH residents should be carefully considered when planning and implementing health care programs in these facilities.

Effects of donepezil on neuropsychiatric symptoms in patients with dementia and severe behavioral disorders

OBJECTIVE

The objective of this study was to conduct exploratory analyses of data pertaining to the efficacy of donepezil treatment of patients with severe behavioral disturbances. Preliminary studies suggest that cholinesterase inhibitors, including donepezil, may reduce behavioral disturbances in patients with Alzheimer disease (AD). Most patients included in clinical trials have had low levels of psychopathology at baseline, and the effect of cholinesterase inhibitors on patients with more severe behavioral disturbances is unknown. The authors report the effects of donepezil on behavioral disturbances in patients with relatively severe psychopathology at baseline.

METHODS

This is a hypothesis-driven secondary analysis of a three-phase study involving donepezil and sertraline. In phase 1, psychotropic agents were withdrawn; in phase 2, patients were treated in an open-label fashion with donepezil for 8 weeks; and in phase 3, patients on donepezil were randomized to receive placebo or sertraline for an additional 12 weeks. The data set analyzed is comprised of the patient population treated with donepezil (without sertraline) for 20 weeks. One hundred twenty patients were included in the analyses. Mean age was 76 years, average Mini-Mental State Examination Score was 18, and mean Neuropsychiatric Inventory (NPI) total score was 30. Primary efficacy assessments were the NPI, the Clinical Global Impression-Improvement, and the Clinical Global Impression-Severity scales. Secondary measures included the Behavioral Pathology in Alzheimer's Disease Rating Scale, The Hamilton Depression Rating Scale, and the Alzheimer's Disease Functional Assessment and Change Scale.

RESULTS

Excellent concurrent validity was noted between the NPI and the Behavioral Pathology in Alzheimer's Disease Rating Scale. The total score of the NPI was significantly reduced over the 20 weeks of therapy with donepezil. Sixty-two percent of patients had at least a 30% reduction in the total NPI score (significantly greater than the number with no meaningful response). Likewise, more patients had total or partial resolution of depression and delusions than those who had no meaningful change. Factor analysis of baseline NPI data revealed five factors, including a psychosis factor, an agitation factor, mood factor, frontal lobe function factor, and appetite and eating disorders factor. Clinically meaningful treatment effect sizes were notable for the delusion factor (0.340) and the mood factor (0.39). There were significant correlations between the Clinical Global Impression-Improvement and reductions in mood and agitation scores.

CONCLUSION

The results of these analyses suggest that donepezil reduces behavioral symptoms, particularly mood disturbances and delusions, in patients with AD with relatively severe psychopathology.

Suicidal behaviour in nursing homes: a survey in a region of north-east Italy

OBJECTIVE

To assess suicide and attempted suicide (AS) rates and their characteristics among older residents in Nursing Homes (NHs) of the Veneto region, in the North-East of Italy.

METHOD

The complete list of NHs was provided by the Regional Department of Health. Structured interviews were completed with NH managers, inquiring about NH, staff and management characteristics, mental health care available and the number of completed and attempted suicides (AS) in 2001 made by residents older than 65 years, occurring either inside or outside NHs. All facilities which reported suicidal events were asked additional information.

RESULTS

In the study period, five completed suicides and eight AS were reported, i.e. a rate of 18.6/100,000 and of 29.7/100,000 respectively. All but one suicides and one AS had a history of mental disorders. Seven subjects had been living in a NH for less than one year. There were no significant differences in the frequency of suicidal events between the facilities which employed or did not employ mental health workers.

CONCLUSION

The suicide rate found in this facility sample is much higher than the rate reported by the Italian National Statistic Institute for the over-65-year-old population of the Veneto Region in 2001, and is similar to the rate reported in a previous study conducted in another country. In Veneto NHs behavioural control of residents, lack of access to a variety of means used for suicidal purposes and medical supervision does not seem to have protected the NH population from suicidal risks.

Self-injurious behaviour in nursing home residents with dementia

OBJECTIVE

To explore the phenomenology and prevalence of Self-Injurious Behaviour (SIB) in nursing home patients with dementia.

METHOD

Cross-sectional study of 110 nursing home patients with dementia. Nurses' ratings of SIB and other behavioural disturbances were compared to independent resident physician ratings of medical charts data pertaining to dementia type, dementia severity, prescribed psychotropic drugs, immobility and measures to restrain the patient. Instruments used were the Overt Aggression Scale (OAS, modified), Behaviour Rating Scale for Psychogeriatric Inpatients (GIP), Rating scale for Older Patients (BOP).

RESULTS

SIB was observed in 22% of the dementia patients. Pinching or scratching oneself and banging one's fist against objects were most frequently reported. Five patients showed a combination of two types of SIB. As expected, SIB was modestly related to Aimless repetitive behaviour and Aggression and no association was found between SIB and Apathy. Correlates of SIB were prescribed psychotropics (i.e. benzodiazepines), immobility and measures to restrain the patient.

CONCLUSIONS

Preliminary data suggest that SIB is a specific psychopathological phenomenon that is highly prevalent in nursing home patients with dementia. Future research should focus on the aetiology and treatment of SIB.

The relationship between self-destructive behaviour and nursing home environment

The aim of this study was to explore the relationship between self-destructive behaviour and nursing home environment. We performed a cross-sectional study comprising 647 residents in 11 nursing homes in Sydney, Australia using the Harmful Behaviours Scale (HBS), Abbreviated Mental Test Scale and the Resident Classification Index. The Directors of Nursing completed a questionnaire that rated physical design, staff and resident characteristics and demographics were obtained from nursing home records. On regression analysis a greater number of design features for frail and residents with dementia in general, and increased security measures were associated with greater HBS total score and risk-taking and passive self-harm subscales. A residential environment in which the residents were more functionally dependent and more likely to be in a shared room, managerial policies less geared towards managing difficult behaviour and less staff availability and training were associated with the 'uncooperativeness' factor. There were no significant predictors of the other two factors. The relationship between nursing home environment and self-destructive behaviours and the environment is complex and there needs to be an individualized approach to placement.

Types of nursing home residents with self-destructive behaviours: analysis of the Harmful Behaviours Scale

OBJECTIVE

To investigate the types of self-destructive behaviours identified by the Harmful Behaviours Scale (HBS) and the variables associated with them.

METHOD

A cross sectional survey involving 647 residents in 11 nursing homes in the eastern suburbs of Sydney, Australia. The following instruments were used: Harmful Behaviours Scale (HBS); Behavioural Pathology in Alzheimer's Disease Rating Scale; Functional Assessment Staging Scale; Resident Classification Index; Health of the Nation Outcome Scale; Even Briefer Assessment Scales for Depression; Abbreviated Mental Test Scale; and the suicide item from the Structured Hamilton Depression Rating Scale. Diagnosis of dementia was obtained from nursing home records.

RESULTS

Latent class analysis of the HBS identified four groups of residents, described as 'aggressive resistant' (34.9%), 'food refusal' (26.8%), 'behaviourally disturbed' (5.4%) and a 'non-symptomatic' group (33.0%) with little self-destructive behaviour. The behaviourally disturbed group engages in a widespread combination of direct and indirect self-destructive behaviours and displays other behavioural and psychological symptoms of dementia. In contrast, the food refusal group whose only behavioural symptom was refusal to eat and drink had the most cognitive impairment and did not show higher levels depression or suicidal ideation.

CONCLUSIONS

We have found three groups of residents with self-destructive behaviours and each group is associated with a different pattern of variables.
