Improving the outcomes of the South Australian mental health court: an examination of the predictors of success

 This thesis investigated the role that mental health problem-solving courts play within the Australian criminal justice system. It demonstrated that these courts can be an effective solution in the delivery of effective justice responses to vulnerable offenders, if administered in a manner that focuses on risk rather than clinical variables.

Mental health diversion courts : some directions for further development

Recent years have seen a growth in the number of specialist courts operating in Australia, including those which aim to address the needs of mentally disordered offenders. This article describes some of the key characteristics of mental health courts, using case studies from the most established court in Australia, the South Australian Magistrates Court Diversion Program (MCDP). This is followed by a consideration of some factors that may affect the future development of this type of program. It is concluded that there is a need to pay careful attention to issues of risk assessment and risk management if the dual goals of improving both the health of individual and the safety of the community are to be realised.

Mental health diversion courts: a two year recidivism study of a South Australian mental health court program.

The need to develop specialized judicial processes to deal with offenders with mental illnesses is now widely recognized and has led to the introduction of mental health court diversion programs around the world. At present, however, there is only limited evidence from which to assess the impact of these initiatives. This paper describes the South Australian model of diversion, with specific reference to the relationship between identified participant characteristics, program compliance rates, and re-offending outcomes. The results of a two-year recidivism study suggest that involvement with the program has a positive impact on recidivism, but that this is independent from the individual's level of success in the program. Lower risk offenders were more likely to achieve successful outcomes than those in the higher risk categories. The implications of these results, as well the factors that might inform the ongoing development of mental health court programs, are discussed.

Accountants and valuations in Australian family court proceedings

This paper investigates issues related to the role of accountants in presenting expert evidence in the form of share valuations in Family Court of Australia proceedings. By providing a background to the valuation rules applied by the Family Court and examining relevant cases, the paper emphasises that considerable ambiguity exists. The paper highlights some of the inconsistencies that are evident from reported decisions and stresses the difficulties that judges have experienced with valuations presented by accountants in Family Court cases. It is evident that the courts, despite the legal precedents, continue to have considerable difficulty with valuation issues and methodologies. By exploring issues related to accounting based valuations in the context of Australian family law cases, the present paper examines accounting in a particular social and institutional setting. The paper is interdisciplinary in nature, in that issues extending over accounting, finance and legal boundaries are considered.

Hepatitis C virus infection in South Australian prisoners : seroprevalence, seroconversion, and risk factors

Objectives : To determine entry antibody seroprevalence and seroconversion to hepatitis C virus (HCV) and associated risk factors in newly incarcerated prisoners.

Methods : Males and females entering South Australian prisons completed risk factor surveys and were offered HCV-antibody testing. Participants completed additional surveys and, if HCV-negative at last test, underwent further antibody tests at 3-monthly intervals for up to 15 months. Data were analyzed using univariate and multivariate techniques.

Results : HCV seroprevalence among 662 prison entrants was estimated at 42%. Previous injecting history was highly prevalent at entry (64%) and both community and prison injecting independently predicted entry HCV status. Tattooing was not an important risk factor. While community exposure could not be ruled out, three seroconversions were noted in 148 initially HCV-seronegative individuals occurring in a median 121 days – 4.6 per 100 person-years. Prison injecting was infrequently reported, but HCV-seropositive participants were significantly more likely to commence IDU in prison than seronegative participants (p = 0.035).

Conclusions : Entry HCV seroprevalence in South Australian prisoners is extremely high and may have contributed to a ‘ceiling effect’, minimizing the observable seroconversion rate. Greater frequency of injecting among those already infected with HCV represents a significant threat to other prisoners and prison staff.

Power and production in site-based management: the responses of women secondary principals to structural reform in South Australian education

After describing and analysing the purpose and shape of structural reform in Australia, the author uses the data gained from interviews with 16 South Australian women principals, to examine its effects on the work of principals. She uses her analysis to issue some warnings about the current moves to Local School Management in South Australia

Effective anger intervention for indigenous prisoners : research and development in a South Australian study

Although the need for the development and provision of culturally appropriate rehabilitation programs for offenders is widely acknowledged, there is a lack of empirical data that can be used as the basis for the development of new programs. This paper reports the findings of two studies - first a qualitiative study exploring the meaning of anger for Indigenous men in prison; and second a comparison of Indigenous and non-Indigenous male prisoners on a range of measures relevant to the experience of anger by indigenous prisoners in Australia. The results suggest that Indigenous participants are more likely to experience symptoms of early trauma, have greater difficulties identifying and describing feelings and perceive higher levels of discrimination than non-Indigenous prisoners. The implications of this work for the development of culturally appropriate and effective anger management programs for indigenous male prisoners and those from other imnoirty cultural groups are discussed.

Options for change in the Australian cervical cancer screening program in context of HPV detection and vaccination

Introduction:
Cervical cancer screening has been implemented for over a decade in Australia and has significantly reduced the mortality and morbidity of the disease. The emergence of new technologies for cervical cancer, such as the Human Papillomavirus (HPV) vaccine and DNA testing has encouraged debate regarding the effective use of resources in cervical cancer prevention. The present study evaluates the cost-effectiveness, from a health sector perspective, of various screening strategies in the era of these new technologies.

Methods:
A stochastic epidemiological model using a discrete event and continuous algorithm was developed to describe the natural history of cervical cancer. By allowing one member of the cohort into the model at a time, this micro-simulation model encompasses the characteristics of heterogeneity and can track individual life histories. To evaluate the cost-effectiveness of the HPV vaccine a Markov model was built to simulate the effect on the incidence of HPV and subsequent cervical cancer. A number of proposed screening strategies were evaluated with the stochastic model for the application of HPV DNA testing, with changes in the screening interval and target population. Health outcomes were measured by Disability-Adjusted Life-Years (DALYs), adjusted for application within an evaluation setting (i.e. the mortality component of the DALY was adjusted by a disability weight when early mortality due to cervical cancer is avoided). Costs in complying with the Australian updated guidelines were assessed by pathway analysis to estimate the resources associated with cervical cancer and its pre-cancerous lesion treatment. Sensitivity analyses were performed to investigate the key parameters that influenced the cost-effectiveness results.

Results:
Current practice has already brought huge health gain by preventing more than 4,000 deaths and saving more than 86,000 life-years in a cohort of a million women. Any of the alternative screening strategies alter the total amount of health gain by a small margin compared to current practice. The results of incremental analyses of the alternative screening strategies compared to current practice suggest the adoption of the HPV DNA test as a primary screening tool every 3 years commencing at age 18, or the combined pap smear/HPV test every 3 years commencing at age 25, are more costly than current practice but with reasonable ICERs (AUD$1,810 per DALY and AUD$18,600 per DALY respectively). Delaying commencement of Pap test screening to age 25 is less costly than current practice, but involves considerable health loss. The sensitivity analysis shows, however, that the screening test accuracy has a significant impact on these conclusions. Threshold analysis indicates that a sensitivity ranging from 0.80 to 0.86 for the combined test in women younger than 30 is required to produce an acceptable incremental cost-effectiveness ratio.

Conclusions:
The adoption of HPV and combined test with an extended screening interval is more costly but affordable, resulting in reasonable ICERs. They appear good value for money for the Australian health care system, but need more information on test accuracy to make an informed decision. Potential screening policy change under current Australian HPV Vaccination Program is current work in progress. A Markov model is built to simulate the effect on the incidence of HPV and subsequent cervical cancer. Adoption of HPV DNA test as a primary screening tool in the context of HPV vaccination is under evaluation.
