The utility of extended outpatient civil commitment.

OBJECTIVE: This study considers three hypotheses regarding the impact of extended involuntary outpatient commitment orders on services utilization. METHOD: Service utilization of Victorian Psychiatric Case Register (VPCR) patients with extended (> or =180 day) outpatient commitment orders was compared to that of a diagnostically-matched treatment compliant group with similarly extended (> or =180 day) periods of outpatient care (N=1182)--the former receiving care during their extended episode on an involuntary basis while the latter participated in care voluntarily. Pre/post first extended episode mental health service utilization was compared via paired t tests with individuals as their own controls. Logistic and OLS regression as well as repeated measures ANOVA via the GLM SPSS program and post hoc t tests were used to evaluate between group and across time differences. RESULTS: Extended episodes of care for both groups were associated with subsequent reduced use of hospitalization and increases in community treatment days. Extended orders did not promote voluntary participation in the period following their termination. Community treatment days during the extended episode for those on orders were raised to the level experienced by the treatment compliant comparison group during their extended episode and maintained at that level via subsequent renewal of orders throughout the patients' careers. Approximately six community treatment days were required for those on orders to achieve a one-day reduction in hospital utilization following the extended episode. CONCLUSION: Outpatient commitment for those on extended orders in the Victorian context enabled a level of community-based treatment provision unexpected in the absence of this delivery system and provided an alternative to hospitalization.

The relationship between media reporting of suicide and actual suicide in Australia.

This study aimed to determine whether media items about suicide were associated with differential increases in actual suicides. Data were available on 4,635 suicide-related items appearing in Australian newspapers and on radio and television news and current affairs shows between March 2000 and February 2001. These data were combined with national data on completed suicides occurring during the same period, by a process that involved identifying the date and geographical reach of the media items and determining the number of suicides occurring in the same location in selected weeks pre- and post-item. Regression analyses were conducted to determine whether the likelihood of an increase in post-item suicides could be explained by particular item characteristics. We found that 39% of media items were followed by an increase in male suicides, and 31% by an increase in female suicides. Media items were more likely to be associated with increases in both male and female suicides if they occurred in the context of multiple other reports on suicide (versus occurring in isolation), if they were broadcast on television (versus other media), and if they were about completed suicide (versus attempted suicide or suicidal ideation). Different item content appeared to be influential for males and females, with an increase in male suicides being associated with items about an individual's experience of suicide and opinion pieces, and an increase in female suicides being associated with items about mass- or murder-suicide. Item prominence and quality were not differentially associated with increases in male or female suicides. Further research on this topic is required, but in the meantime there is a need to remain vigilant about how suicide news is reported. Mental health professionals and suicide experts should collaborate with media professionals to try to balance 'public interest' against the risk of harm.

Conditional release: a less restrictive alternative to hospitalization?

OBJECTIVE: This study examined conditional release--that is, involuntary outpatient commitment orders upon release from hospitalization--as a least restrictive alternative to psychiatric hospitalization in Victoria, Australia. METHODS: Records were obtained from the Victorian Psychiatric Case Register for patients who experienced psychiatric hospitalization: between 1990 and 2000 a total of 8,879 patients were given conditional release and 16,094 were not. RESULTS: Compared with the group that was hospitalized but did not receive a conditional release, the group that received a conditional release was more likely to have more prior hospitalizations of greater than average duration. Patients with schizophrenia were more likely to be given conditional release. Patients given conditional release experienced a care pattern involving briefer inpatient episodes (8.3 fewer days per episode), more inpatient days, and longer duration of restrictive care--that is, combined inpatient and conditional release periods (5.1 more days per month in care). CONCLUSIONS: For patients at risk of long-term hospitalization, conditional release may help to shorten inpatient episodes by providing a least restrictive alternative to continued hospitalization. However, patients who were given conditional release doubled the amount of days they spent under restrictive care, compared with the amount of time they previously spent in the hospital before entering a period of combined inpatient and conditional release commitment. Additional oversight may have led to more frequent hospitalization. This consequence raises new questions regarding the possible benefits of such extended oversight and new challenges for release planning using conditional release as a least restrictive method of care.

Effect of conditional release from hospitalization on mortality risk.

OBJECTIVES: This study considered the protective value provided by conditional release. It assessed the contribution of conditional release to mortality risk among patients with mental disorders severe enough to require psychiatric hospitalization during a mental health treatment span of 13.5 years in Victoria, Australia. METHODS: Death records were obtained from the Australian National Death Index for a sample of 24,973 Victorian Psychiatric Case Register patients with a history of psychiatric hospitalizations: 8,879 had experienced at least one conditional release during community care intervals and 16,094 had not. Risk of death was assessed with standardized mortality ratios of the general population of Victoria. Relative risk of death among patients with and without past experience of conditional release was computed with risk and odds ratios. The contribution of conditional release to mortality, taking into account use of community care services, age, gender, inpatient experience, and diagnosis, as well as other controls, was assessed with logistic regression. RESULTS: Patients who had been hospitalized showed higher mortality risk than the general population. Sixteen percent (4,034) died. Patients exposed to conditional release, however, had a 14 percent reduction in probability of non-injury-related death and a 24 percent reduction per day on orders in the probability of death from injury compared with those not offered such oversight throughout their mental health treatment, all other factors taken into account. CONCLUSIONS: Conditional release can offer protective oversight for those considered dangerous to self or others and appears to reduce mortality risk among those with disorders severe enough to require psychiatric hospitalization.

Factors in the selection of patients for conditional release from their first psychiatric hospitalization.

OBJECTIVE: This study examined a sample of patients in Victoria, Australia, to identify factors in selection for conditional release from an initial hospitalization that occurred within 30 days of entry into the mental health system. METHODS: Data were from the Victorian Psychiatric Case Register. All patients first hospitalized and conditionally released between 1990 and 2000 were identified (N=8,879), and three comparison groups were created. Two groups were hospitalized within 30 days of entering the system: those who were given conditional release and those who were not. A third group was conditionally released from a hospitalization that occurred after or extended beyond 30 days after system entry. Logistic regression identified characteristics that distinguished the first group. Ordinary least-squares regression was used to evaluate the contribution of conditional release early in treatment to reducing inpatient episodes, inpatient days, days per episode, and inpatient days per 30 days in the system. RESULTS: Conditional release early in treatment was used for 11 percent of the sample, or more than a third of those who were eligible for this intervention. Factors significantly associated with selection for early conditional release were those related to a better prognosis (initial hospitalization at a later age and having greater than an 11th grade education), a lower likelihood of a diagnosis of dementia or schizophrenia, involuntary status at first inpatient admission, and greater community involvement (being employed and being married). When the analyses controlled for these factors, use of conditional release early in treatment was significantly associated with a reduction in use of subsequent inpatient care.

Remunerating private psychiatrists for participating in case conferences.

BACKGROUND: On 1 November 2000, a series of new item numbers was added to the Medicare Benefits Schedule, which allowed for case conferences between physicians (including psychiatrists) and other multidisciplinary providers. On 1 November 2002, an additional set of numbers was added, designed especially for use by psychiatrists. This paper reports the findings of an evaluation of these item numbers. RESULTS: The uptake of the item numbers in the three years post their introduction was low to moderate at best. Eighty nine psychiatrists rendered 479 case conferences at a cost to the Health Insurance Commission of $70,584. Psychiatrists who have used the item numbers are generally positive about them, as are consumers. Psychiatrists who have not used them have generally not done so because of a lack of knowledge, rather than direct opposition. The use of the item numbers is increasing over time, perhaps as psychiatrists become more aware of their existence and of their utility in maximising quality of care. CONCLUSION: The case conferencing item numbers have potential, but as yet this potential is not being realised. Some small changes to the conditions associated with the use of the item numbers could assist their uptake.

A review of the psychometric properties of the Health of the Nation Outcome Scales (HoNOS) family of measures.

BACKGROUND: The Health of the Nation Outcome Scales was developed to routinely measure outcomes for adults with mental illness. Comparable instruments were also developed for children and adolescents (the Health of the Nation Outcome Scales for Children and Adolescents) and older people (the Health of the Nation Outcome Scales 65+). All three are being widely used as outcome measures in the United Kingdom, Australia and New Zealand. There is, however, no comprehensive review of these instruments. This paper fills this gap by reviewing the psychometric properties of each. METHOD: Articles and reports relating to the instruments were retrieved, and their findings synthesised to assess the instruments' validity (content, construct, concurrent, predictive), reliability (test-retest, inter-rater), sensitivity to change, and feasibility/utility. RESULTS: Mostly, the instruments perform adequately or better on most dimensions, although some of their psychometric properties warrant closer examination. CONCLUSION: Collectively, the Health of the Nation Outcome Scales family of measures can assess outcomes for different groups on a range of mental health-related constructs, and can be regarded as appropriate for routinely monitoring outcomes.

Course of substance misuse and daily tobacco use in first-episode psychosis.

BACKGROUND: Study of the course of substance misuse and daily tobacco use in first-episode psychosis may enhance detection and treatment of these substance-related problems. METHODS: This 15-month follow-up study examined the course of substance misuse and daily tobacco use in 103 individuals treated for first-episode psychosis. RESULTS: Three-quarters (72.6%) of patients with lifetime substance misuse, or half (51.5%) of all patients, continued substance misuse (primarily cannabis) during the 15-month follow-up period. There was a significant reduction in the rate of any substance misuse (70.9% versus 53.4%) but not daily tobacco use (76.7% versus 75.7%) between baseline and 15-month follow-up. Patients who continued substance misuse showed a significant reduction in the severity and frequency of substance use between baseline and follow-up. Patients who continued substance misuse were more likely to be younger, male and single, less likely to have completed secondary school, and more likely to have had more severe cannabis use prior to entry to treatment compared to patients who ceased substance misuse. DISCUSSION: A significant proportion of young patients treated for first-episode psychosis are at risk of mental and physical health problems associated with substance misuse and/or regular tobacco use.

Patterns and predictors of substance use disorders and daily tobacco use in first-episode psychosis.

OBJECTIVE: To investigate the patterns and predictors of substance use disorders (SUD) and daily tobacco use in first-episode psychosis (FEP). METHOD: In this study, consecutive admissions of 126 patients with an initial presentation for FEP were recruited from three psychiatric services. Each patient was assessed with a comprehensive assessment package in order to collect demographic information, to diagnose psychotic disorders and SUD, to estimate the duration of untreated psychosis and to assess premorbid functioning and the severity of psychiatric symptoms. RESULTS: The rates of lifetime SUD and daily tobacco use were 71% and 77%, respectively. The onset of SUD pre-dated the onset of positive psychotic symptoms in 91% of relevant cases. In multivariate analyses, male gender, younger age, Australian birth and unemployed status were the most consistent demographic predictors of SUD and daily tobacco use. There were no associations found between SUD and symptom severity, premorbid adjustment, psychotic disorder diagnosis or hospitalization. CONCLUSIONS: Male gender and younger age are reliable predictors of SUD in FEP. Patients with and without SUD appear to have similar clinical characteristics at initial presentation.

Lessons from the National Mental Health Integration Program.

Three projects were funded under the national Mental Health Integration Program (MHIP) in 1999, each of which employed a different model aimed at improving linkages between disparate parts of the mental health system. A national evaluation framework guided local evaluations of these projects, and this paper presents a synthesis of the findings. For providers, the projects improved working relationships, created learning opportunities and increased referral and shared care opportunities. For consumers and carers, the projects resulted in a greater range of options and increased continuity of care. For the wider system, the projects achieved significant structural and cultural change. Cost-wise, there were no increases in expenditure, and even some reductions. Many of the lessons from the projects (and their evaluations) may be generalised to other mental health settings and beyond.

Personality disorders in the community: results from the Australian National Survey of Mental Health and Well-being Part III. Relationships between specific type of personality disorder, Axis 1 mental disorders and physical conditions with disability and health consultations.

BACKGROUND: The aim of the present study was to examine in a national survey sample the risks of having a specific personality disorder (PD) and associations with gender, of having one or more physical conditions, of having one or more Axis 1 conditions, and of the severity (or degree) of disability. We also examined the association of specific PDs with having sought a consultation for health or mental health problems with a general practitioner (GP), a psychologist, or psychiatrist over the past 12 months. METHOD: Data were derived from the Australian National Mental Health and Well-Being Survey, conducted between May and August 1997. A stratified random sample of households was generated, from which all persons aged 18 or over were considered potential interviewees. There were 10,641 survey respondents, this representing a response rate of 78%. Each interviewee was asked 59 questions indexing specific ICD-10 PD criteria. RESULTS: Logistic regressions identified that some specific PDs, especially borderline PD, were more strongly associated with having one or more Axis I conditions, greater mental disability and lost days of total and partial role functioning than having No PD, and that others, notably anankastic PD, were less likely to be associated with the same variables. Some specific PDs, again most notably borderline PD, were more associated than others, again most notably anankastic PD, with having sought mental health consultations from GPs, psychiatrists, and psychologists. By contrast, PD associations with gender, physical conditions, physical disability and health consultations with the three professional groups were weaker as reflected in the comparatively smaller odds ratios and were also less consistent than the pattern with the previously mentioned variables. CONCLUSION: The study reports findings from a nationwide survey and, as such, the data are less influenced by the selection and setting bias found in most other studies investigating these variables. The findings of the study do point to some specific PDs, such as borderline PD, being associated with greater Axis 1 psychopathology, disability and mental health consultations than others, such as anankastic PD. It appears that although anankastic PD in itself is associated with more disability than having No PD, it becomes significantly more disabling when it is associated with other comorbid PDs.

Impact of child sexual abuse on mental health: prospective study in males and females.

BACKGROUND: The lack of prospective studies and data on male victims leaves major questions regarding associations between child sexual abuse and subsequent psychopathology. AIMS: To examine the association between child sexual abuse in both boys and girls and subsequent treatment for mental disorder using a prospective cohort design. METHOD: Children (n=1612; 1327 female) ascertained as sexually abused at the time had their histories of mental health treatment established by data linkage and compared with the general population of the same age over a specified period. RESULTS: Both male and female victims of abuse had significantly higher rates of psychiatric treatment during the study period than general population controls (12.4% v. 3.6%). Rates were higher for childhood mental disorders, personality disorders, anxiety disorders and major affective disorders, but not for schizophrenia. Male victims were significantly more likely to have had treatment than females (22.8% v.10.2%). CONCLUSIONS: This prospective study demonstrates an association between child sexual abuse validated at the time and a subsequent increase in rates of childhood and adult mental disorders.

Epidemiological analysis of electroconvulsive therapy in Victoria, Australia.

OBJECTIVE: To determine the population-based utilization rate of electroconvulsive therapy (ECT) in Victoria between 1998-1999, to examine the characteristics of the ECT treated group, and to identify patient factors independently associated with differential rates of ECT treatment. METHOD: Electroconvulsive therapy is reported under statute in Victoria, Australia. Crude, age-adjusted and age-sex specific utilization rates were calculated using this statutory data for the 1998-1999 financial year and estimated mid-year populations from the Australian Bureau of Statistics. Descriptive characteristics of those treated with ECT were derived from the statutory data. Patient factors associated with an increased likelihood of ECT in the public sector were explored with logistic regression analysis, using non-ECT treated mental health patients from the Victorian Psychiatric Case Register as the reference population. RESULTS: The crude treated-person and age-adjusted rates for the State (both public and private sectors) were 39.9 and 44.0 persons per 100 000 resident population per annum, respectively. The crude and age-adjusted administration rates were 330.3 and 362.6 ECT administrations per 100 000 resident population per annum, respectively. Age-sex specific rates varied by age and sex, with rates generally increasing with age and female sex. Overall, 62.8% of the treated group were women, 32.9% aged over 64, and 75.2% had depression. Diagnosis, age and sex each independently predicted ECT in the public sector, with diagnosis the most important factor, followed by age then sex. CONCLUSIONS: Despite decades of use, the appropriate rate of ECT utilization is still unclear. Further research should be directed at exploring the factors, including provider variables, determining ECT treatment.

Personality disorders in the community: results from the Australian National Survey of Mental Health and Wellbeing Part II. Relationships between personality disorder, Axis I mental disorders and physical conditions with disability and health consultations.

BACKGROUND: The aims of this study were threefold. First, to ascertain whether personality disorder (PD) was a significant predictor of disability (as measured in a variety of ways) over and above that contributed by Axis I mental disorders and physical conditions. Second, whether the number of PD diagnoses given to an individual resulted in increasing severity of disability, and third, whether PD was a significant predictor of health and mental health consultations with GPs, psychiatrists, and psychologists, respectively, over the last 12 months. METHOD: Data were obtained from the National Survey of Mental Health and Wellbeing, conducted between May and August 1997. A stratified random sample of households was generated, from which all those aged 18 and over were considered potential interviewees. There were 10,641 respondents to the survey, and this represented a response rate of 78 %. Each interviewee was asked questions indexing specific ICD-10 PD criteria. RESULTS: Five measures of disability were examined. It was found that PD was a significant predictor of disability once Axis I and physical conditions were taken into account for four of the five disability measures. For three of the dichotomously-scored disability measures, odds ratios ranged from 1.88 to 6.32 for PD, whilst for the dimensionally-scored Mental Summary Subscale of the SF-12, a beta weight of -0.17 was recorded for PD. As regards number of PDs having a quasi-linear relationship to disability, there was some indication of this on the SF-12 Mental Summary Subscale and the two role functioning measures, and less so on the other two measures. As regards mental consultations, PD was a predictor of visits to GPs, psychiatrists and psychologists, over and above Axis I disorders and physical conditions. CONCLUSION: The study reports findings from a nationwide survey conducted within Australia and as such the data are less influenced by the selection and setting bias inherent in other germane studies. However, it does support previous findings that PD is a significant predictor of disability and mental health consultations independent of Axis I disorders and physical conditions.
