Changes in determinants of compulsory community treatment over 11 years. A population-based analysis of linked mental health databases

Variations between, and within, jurisdictions in the use of community treatment orders and other compulsory community treatment: study of 402 060 people across four Australian states

BACKGROUND

The use of compulsory community treatment (CCT) in Australia is some of the highest worldwide despite limited evidence of effectiveness. Even within Australia, use varies widely across jurisdictions despite general similarities in legislation and health services. However, there is much less information on whether variation occurs within the same jurisdiction.

AIMS

To measure variations in the use of CCT in a standardised way across the following four Australian jurisdictions: Queensland, South Australia, New South Wales (NSW) and Victoria. We also investigated associated sociodemographic variables.

METHODS

We used aggregated administrative data from the Australian Institute of Health and Welfare.

RESULTS

There were data on 402 060 individuals who were in contact with specialist mental health services, of whom 51 351 (12.8%) were receiving CCT. Percentages varied from 8% in NSW to 17.6% in South Australia. There were also wide variations within jurisdictions. In NSW, prevalence ranged from 2% to 13%, in Victoria from 6% to 24%, in Queensland from 11% to 25% and in South Australia from 6% to 36%. People in contact with services who were male, single and aged between 25 and 44 years old were significantly more likely to be subject to CCT, as were people living in metropolitan areas or those born outside Oceania.

CONCLUSIONS

There are marked variations in the use of CCT both within and between Australian jurisdictions. It is unclear how much of this variation is determined by clinical need and these findings may be of relevance to jurisdictions with similar clinician-initiated orders.

Participation in the National Bowel Cancer Screening Program by people with severe mental illness, Australia, 2006-2019: a national data linkage study

OBJECTIVE

To compare rates of participation in the National Bowel Cancer Screening Program (NBCSP) and follow-up for people with severe mental illness with those for people without severe mental illness or not prescribed antidepressants.

STUDY DESIGN

Retrospective cohort study; analysis of de-identified linked NBCSP, Pharmaceutical Benefits Scheme (PBS), and Medicare Benefits Schedule (MBS) data.

SETTING

Australia, 2006-2019.

PARTICIPANTS

People aged 50-74 years (NBCSP-eligible) with severe mental illness, defined as those dispensed two or more prescriptions for second generation antipsychotics or for lithium (PBS data), and a random sample of people aged 50-74 years eligible for Medicare-subsidised services but never prescribed psychotropic medications (antipsychotics, lithium, antidepressants).

MAIN OUTCOME MEASURES

NBCSP participation (returned faecal occult blood test sample), valid test result, positive test result, and follow-up colonoscopy rates.

RESULTS

A total of 119 475 people with severe mental illness and 1 090 574 control group people were included in our analyses. The proportion of women was larger in the severe mental illness group (51.3%) than the control group (48.7%), as were the proportions who lived in inner regional areas (23.5% v 19.1%) or in areas in the lowest socio-economic quintile (21.8% v 14.7%). The NBCSP participation rate was lower among people with severe mental illness (adjusted incidence rate ratio [IRR], 0.70; 95% confidence interval [CI], 0.69-0.84). The proportion of valid test results was smaller for people with severe mental illness (95.9% v 98.7%; adjusted IRR, 0.97; 95% CI, 0.96-0.99), and the positive test result proportion larger (12.3% v 6.6%; adjusted IRR, 2.01; 95% CI, 1.94-2.09). The proportion of positive test results followed by colonoscopy was smaller for people with severe mental illness (71.7% v 82.6%; adjusted IRR, 0.88; 95% CI, 0.85-0.92).

CONCLUSIONS

People with severe mental illness were less likely to participate in the NBCSP or to undergo colonoscopy after a positive test result than other Australians. These differences may contribute to higher colorectal cancer mortality among people with severe mental illness. The contributions of differences in cancer stage at diagnosis and subsequent treatment to higher colorectal cancer mortality require further study.

Are mental health nurses meeting the requirements of second health professionals in presenting opinions to the court?

WHAT IS KNOWN ON THE SUBJECT?: Mental health legislation is currently under review following recommendations for repeal and replacement. Through the statutory role of the second health professional, mental health nurses are in a strong position to offer a unique clinical perspective, engagement and advocacy for tangata whaiora (person seeking wellness) and whānau. Māori are more likely to be subject to a compulsory treatment order than non-Māori. Whānau involvement in care is a core element to well-being from a Te Ao Māori (Māori world view) perspective. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: Understanding the level of whānau involvement in the MHA process. Understanding challenges for nursing practice for consideration in the current review of MHA legislation. Identification of the opportunity nurses have to contribute to reducing high rates of Māori under CTOs. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: The current MHA review needs to include the resourcing required to support the clinicians practising in statutory roles. More emphasis is needed to build the cultural knowledge and capability of the nursing workforce to integrate principles of a Te Ao Māori worldview into care delivery. These learnings highlight the importance of nursing responsibility in the SHP role. ABSTRACT: Introduction Clinical practice within statutory roles is an important issue for the nursing profession. There is increasing involvement of nurses undertaking statutory roles and opportunities for nurses to advocate and offer their unique clinical opinion regarding the need for restrictive measures imposed by mental health act legislation. Aim The aim of this study was to analyse whether registered nurses who undertake the role of second health professional (SHP) within New Zealand's Mental Health (Compulsory Assessment and Treatment) Act (1992) (MHA) are meeting the expectations of that role. Method A retrospective analysis of 156 cases was undertaken of clinical reports completed by registered nurses. The reports were measured against an established competency framework modified to include MHA expectations for whānau (family) involvement. Results From a sample of 156 cases, 22 were identified as reviews of initial orders for assessment and treatment while 134 were opinions related to the application for a compulsory treatment order (CTO). In most cases, reports achieved a good standard. There were limitations in nurses completing the documentation to the required standard, and adaptations were evident in efforts to meet clinical and legal expectations. There was a significant absence of evidence of whānau consultation. Discussion Resourcing through education, support and ongoing development are required to ensure that nurses are equipped to meet the expectations of the legislation. There is an opportunity for nurses to influence decision-making and support the reduction in use of community treatment orders. A review of the existing competency framework is required to include cultural approaches and involvement of whānau. Implications for Practice It is important to understand the factors that strengthen nursing practice to improve health outcomes and tangata whaiora and whānau experience. This study uses methods of clinical audit to describe current practice and establish an evidence base to measure change. It also offers important learnings for consideration within MHA legislation review and for nursing workforce development.

Examining the health and criminal justice characteristics for young people on compulsory community treatment orders: An Australian birth cohort and data linkage study

BACKGROUND

Most studies on the predictors and effectiveness of community treatment orders (CTOs) are restricted to health-related variables and do not consider forensic contacts as established by criminal justice databases or predictors from birth. We used linked administrative health and criminal justice data for a birth cohort in Queensland, Australia to investigate the characteristics and outcomes of people placed on CTOs.

METHODS

CTOs were identified from administrative data for hospital admissions and community mental health service contacts for a population cohort of 45,141 individuals born in Queensland in 1990. These data were linked with administrative court records, with individuals followed up to age 23/24 years. Logistic regression analyses were used to examine characteristics associated with CTO placement and Tobit regression analyses to examine factors predicting health and criminal justice outcomes in the following year.

RESULTS

There were 211 CTO cases by age 23/24 years, for whom it was possible to identify 413 controls on voluntary treatment. Non-affective psychoses [F20-F29] were the strongest predictors of CTO placement (OR_adj = 4.07, 2.77-5.99) followed by a court appearance (OR_adj = 1.99, 1.28-3.09). CTOs were associated with greater, not lower, subsequent psychiatric hospital admissions, inpatient bed-days and community mental health service contacts, although on sensitivity analyses psychiatric hospital admissions were the same as voluntary controls. CTOs were not associated with more subsequent court appearances despite higher rates of offending before CTO placement.

CONCLUSIONS

Both clinical and forensic variables can determine CTO placement and, on adjustment for these covariates, CTOs were not associated with reductions in psychiatric hospital admission, time spent as an inpatient, or subsequent court appearances. The latter finding might mean that CTOs reduce the risk of offending to that of voluntary controls.

Characteristics of people on community treatment orders in Australia: Data from the 2010 National Survey of High Impact Psychosis

OBJECTIVE

Existing evidence on factors associated with community treatment order placement is largely restricted to administrative data. We utilised the data from a large nationally representative sample to compare the demographic, clinical, social functioning, substance use and service utilisation profiles of people living with psychosis under community treatment orders with those who were not.

METHODS

Participants were grouped based on whether they had been subject to a community treatment order in the past 12 months or not. We conducted logistic regressions to examine demographic, clinical, social functioning, substance use and service utilisation profiles associated with the two groups.

RESULTS

People who had recently been subject to community treatment orders were more likely to be treated with long-acting injectable antipsychotics and lacked insight but were less likely to report suicidal ideation. They also had higher psychiatric inpatient admission rates but a lower frequency of general practitioner visits.

CONCLUSION

People on community treatment orders in Australia may differ from those who are not under a community treatment order in their treatment needs. Resources and care provision must match the needs of this particularly vulnerable group.

Increased autonomy with capacity-based mental health legislation in Norway: a qualitative study of patient experiences of having come off a community treatment order

Background

Capacity-based mental health legislation was introduced in Norway on 1 September 2017. The aim was to increase the autonomy of patients with severe mental illness and to bring mental health care in line with human rights. 

The aim of this study is to explore patient experiences of how far the new legislation has enabled them to be involved in decisions on their treatment after they were assessed as capable of giving consent and had their community treatment order (CTO) revoked due to the change in the legislation.

Method

Individual in-depth interviews were conducted from September 2019 to March 2020 with twelve people with experience as CTO patients. Interviews were transcribed and analysed using thematic analysis inspired by hermeneutics.

Results

Almost all interviewees were receiving the same health care over two years after their CTO was terminated. Following the new legislation, they found it easier to be involved in treatment decisions when off a CTO than they had done in periods without a CTO before the amendment. Being assessed as having capacity to consent had enhanced their autonomy, their dialogues and their feeling of being respected in encounters with health care personnel. However, several participants felt insecure in such encounters and some still felt passive and lacking in initiative due to their previous experiences of coercion. They were worried about becoming acutely ill and again being subjected to involuntary treatment.

Conclusion

The introduction of capacity-based mental health legislation seems to have fulfilled the intention that treatment and care should, as far as possible, be provided in accordance with patients’ wishes. Systematic assessment of capacity to consent seems to increase the focus on patients’ condition, level of functioning and opinions in care and treatment. Stricter requirements for health care providers to find solutions in cooperation with patients seem to lead to new forms of collaboration between patients and health care personnel, where patients have become more active participants in their own treatment and receive help to make more informed choices.

A systematic review and meta-analysis of predictors and outcomes of community treatment orders in Australia and New Zealand

OBJECTIVES

Australia and New Zealand have some of the highest rates of compulsory community treatment order use worldwide. There are also concerns that people from culturally and linguistically diverse backgrounds may have higher rates of community treatment orders. We therefore assessed the health service, clinical and psychosocial outcomes of compulsory community treatment and explored if culturally and linguistically diverse, indigenous status or other factors predicted community treatment orders.

METHODS

We searched the following databases from inception to January 2020: PubMed/Medline, Embase, CINAHL and PsycINFO. We included any study conducted in Australia or New Zealand that compared people on community treatment orders for severe mental illness with controls receiving voluntary psychiatric treatment. Two reviewers independently extracted data, assessing study quality using Joanna Briggs Institute scales.

RESULTS

A total of 31 publications from 12 studies met inclusion criteria, of which 24 publications could be included in a meta-analysis. Only one was from New Zealand. People who were male, single and not engaged in work, study or home duties were significantly more likely to be subject to a community treatment order. In addition, those from a culturally and linguistically diverse or migrant background were nearly 40% more likely to be on an order. Indigenous status was not associated with community treatment order use in Australia and there were no New Zealand data. Community treatment orders did not reduce readmission rates or bed-days at 12-month follow-up. There was evidence of increased benefit in the longer-term but only after a minimum of 2 years of use. Finally, people on community treatment orders had a lower mortality rate, possibly related to increased community contacts.

CONCLUSION

People from culturally and linguistically diverse or migrant backgrounds are more likely to be placed on a community treatment order. However, the evidence for effectiveness remains inconclusive and limited to orders of at least 2 years' duration. The restrictive nature of community treatment orders may not be outweighed by the inconclusive evidence for beneficial outcomes.

Community treatment orders in Western Switzerland: A retrospective epidemiological study

PURPOSE

Community treatment orders (CTOs) are legal procedures that authorise compulsory community mental health care to people affected by severe mental disorders. Nowadays, CTOs are regulated in 75 countries, with important variations in terms of legal criteria and practices. In Switzerland CTOs were introduced on the 1^st January 2013, following the amendment of the Swiss Civil Code. The aim of this study was to provide a first understanding of the use of CTOs in Western Switzerland in terms of incidence and prevalence rates, population profile, orders duration and reasons for discharge.

METHODS

Incidence and prevalence rates of CTOs between 2013 and 2017 were estimated. Survival analysis was used to investigate time to CTO discharge and associated factors. Logistic regression was performed to identify factors associated with CTOs' success as reason for discharge.

RESULTS

CTOs' incidence rates per 100'000 inhabitants ranged between 4.8 for 2013 and 9.6 for 2017, while their prevalence raised from 4.8 to 19.5. People placed under CTO were mainly male, in their forties, of Swiss origin, single and living independently. Primarily affected by Schizophrenia, schizotypal and delusional disorders (F20-F29), they frequently presented substance use problems, and severe danger for themselves. CTOs were mainly ordered by the guardianship authority as a form of conditional release. The estimated mean time to discharge was almost three years. Not being of Swiss origin and being prescribed to take a medication were associated with longer CTO while living in hospital, as a consequence of a long-lasting hospitalisation, and having a non-medical professional in charge of the order were associated with shorter time to discharge. Neither clinical factors nor legal criteria predicted time to discharge. Moreover, spending more days under CTO increased the likelihood of success at discharge, whereas not being of Swiss origin reduced it.

CONCLUSIONS

To the best of our knowledge, no previous studies have examined the CTOs' implementation in Switzerland. CTOs prevalence increased rapidly despite the lack of evidence on positive outcomes. Our results suggested that once under CTO, it takes a long time for a patient to be released, in case of both positive and negative outcomes.

The use of outpatient commitment in Norway: Who are the patients and what does it involve?

PURPOSE

Despite one of the longest histories of using Outpatient Commitment (OC), little is known about the use in the Norwegian context. Reporting from the Norwegian Outpatient Commitment Study, this article aims to: establish the profile of the OC population in Norway; ascertain the legal justification for the use of OC and what OC involves for patients; investigate possible associations between selected patient and service characteristics and duration of OC, and; explore potential differences based on gender or rurality.

METHODS

A retrospective multi-site study, extracting data from the medical records of all patients on OC in six large regional hospitals in 2008-12, with detailed investigation over 36 months of the subsample of patients on first ever OC-order in 2008-09. We use descriptive statistics to establish the profile of the OC population and the legal justification for and the content of OC, and logistic regression to examine factors associated with duration of OC over 36 months.

RESULTS

1414 patients were on OC over the 5 years, and 274 had their first OC in 2008-09. The sample included more men than woman, and three-quarters were diagnosed with schizophrenia. They had long service histories, including involuntary admissions. The legal justification for all OC-orders was the need for treatment, and 18% were additionally justified by dangerousness. The option to initiate OC directly from the community was not used in any of the 274 first ever OC-orders. While 98% of patients were prescribed psychotropic medication, under half had an Involuntary Treatment Order, which under the Norwegian OC regime is required in addition to the OC-order to oblige patients to accept treatment (usually medication). 60% of patients had ≥2 clinical contacts monthly. There were some gender differences in descriptive analyses with men generally being worse off, but no clear pattern in terms of rurality. Patients in the sample had been on OC between one week and 20 years. The median duration of OC over 36 months was 365 days. Three factors contributed to longer duration: the use of the dangerousness criterion; a diagnosis of schizophrenia disorder, and; considerable problems with substance abuse.

CONCLUSION

The characteristics of the OC population in Norway are very similar to that reported in other jurisdictions. Medication seems to be the central focus of OC, yet additional Involuntary Treatment Orders are imposed for less than half of patients. While all OC-orders were justified by the need to ensure treatment, risk seems to be a concern for a subgroup of patients who are kept on for longer. How the 2017 amendment to the mental health act, which precludes compulsion for competent patients unless danger is present, will affect OC use, remains to be seen. Further studies should specifically focus on variation in the use of OC, including at the level of individual clinicians.

Cultural and linguistic diversity increases the likelihood of compulsory community treatment

BACKGROUND

People from culturally and linguistically diverse (CALD) backgrounds are over-represented in compulsory admissions to hospital but little is known about whether this also applies to community treatment orders (CTOs).

AIMS

We investigated any differences between Australian- and foreign-born patients in the likelihood of CTO placement using state-wide databases from Western Australia.

METHODS

Cases and controls from administrative health data were matched on age, sex, diagnosis and time of hospital discharge (the index date). Logistic regression was then used to identify potential predictors of a CTO. We also assessed if any differences in CTO placement between Australian- and foreign-born patients had effects on bed-days or community contacts in the subsequent year.

RESULTS

We identified 2958 CTO cases and controls from November 1997 to December 2008 (total n=5916). Of these, 74% had schizophrenia or other non-affective psychoses. Patients who were born in New Zealand, the United Kingdom or Ireland had very similar rates of CTO placement compared to those who were Australian-born. By contrast, there was a gradient of increasing risk of CTO placement for people born in Continental Europe (OR_adj=1.36; 95% CI=1.07-1.71, p=0.01) and then the Rest of the World (OR_adj=1.61; 95% CI=1.31-1.97, p<0.001). However, there was no evidence of additional benefit in terms of health service use in the following year.

CONCLUSIONS

In common with other coercive treatments, people from culturally and linguistically diverse (CALD) backgrounds are more likely to be placed on CTOs. Further research is needed to establish if this is for similar reasons.
