Although opioid substitution therapy (OST) immediately after prison release reduces mortality, the cost-effectiveness of treatment has not been examined. Therefore, we undertook a cost-effectiveness analysis of OST treatment upon prison release and the prevention of death in the first six months post-release. Population-based, retrospective data linkage study using records of OST entrants (1985-2010), charges and court appearances (1993-2011), prison episodes (2000-2011) and death notifications (1985-2011). New South Wales, Australia. 16,073 people with a history of opioid dependence released from prison for the first time between 1 January 2000 and 30 June 2011. OST treatment compared to no OST treatment at prison release. Mortality and costs (treatment, criminal justice system - court, penalties, prison - and the social costs of crime) were evaluated at six months post-release. Analyses included propensity score matching, bootstrapping and regression. A total of 13,468 individuals...

Individuals in contact with the criminal justice system are a key population of concern to public health. Record linkage studies can be useful for studying health outcomes for this group, but the use of aliases complicates the process of linking records across databases. This study was undertaken to determine the impact of aliases on sensitivity and specificity of record linkage

Objective. This paper reports the findings comparing the obstetrical health, antenatal care, and psychosocial characteristics of pregnant women with a known history of substance dependence (n = 41) and a comparison group of pregnant women attending a general antenatal clinic (n = 47). Method. Face-to-face interviews were used to assess obstetrical health, antenatal care, physical and mental functioning, substance use, and exposure to violence. Results. The substance-dependent group had more difficulty accessing antenatal care and reported more obstetrical health complications during pregnancy. Women in the substance-dependent group were more likely to report not wanting to become pregnant and were less likely to report using birth control at the time of conception. Conclusions. The profile of pregnant women (in specialised antenatal care for substance dependence) is one of severe disadvantage and poor health. The challenge is to develop and resource innovative and effective multisec...

The over-representation of mental illness among homeless people across the globe is well documented. However, there is a dearth of Australian literature on the mental health needs of homeless individuals. Furthermore, longitudinal research examining the factors that contribute to better housing outcomes among this population is sparse. The aim of this research is to describe the mental illness profile of a sample of homeless men in an Australian urban centre (in Sydney) and examine the factors associated with better housing outcomes at 12-month follow-up. A longitudinal survey was administered to 253 homeless men who were involved in the Michael Project: a 3-year initiative which combined existing accommodation support services with assertive case management and access to coordinated additional specialist allied health and support services. A total of 107 participants were followed up 12 months later. The survey examined the demographics of the sample and lifetime mental disorder di...

Using a retrospective cross-sectional study design, we examined smoking patterns and associated neonatal outcomes in infants born to women with a diagnosis of a substance use disorder in pregnancy. Antenatal and birth admissions were linked to midwives data on pregnancy care, services, and outcomes over a 5-year period (1998-2002). Birth admissions were flagged as positive for drug use where a birth admission or any pregnancy admission for that birth involved a cannabis-, opioid-, stimulant-, or alcohol-related ICD-10AM code. There were 4,346 live births to women with a substance-related diagnosis in pregnancy. Women with a substance-related diagnosis (the drug group) had an adjusted odds ratio for smoking during pregnancy of 10.8 (95% CI = 9.9-11.7) relative to women without a substance-related diagnosis (the non-drug group). Women in the drug group also were heavier smokers; 26% smoked 1-10 cigarettes/day and 56% smoked more than 10 cigarettes/day compared with 8% in both groups in the non-drug group. Relative to the drug group, the adjusted odds ratio for quitting smoking during pregnancy in the non-drug group was 3.1 (95% CI = 2.3-4.3). Among women in the drug group, any smoking significantly increased the risk of poor fetal growth, prematurity, and admission to the special care nursery. In conclusion, innovative and effective strategies for tobacco cessation should target pregnant women as a high priority. Further research should identify the models of tobacco cessation most suited to women who also use other substances during pregnancy.

Alcohol exposure in utero is associated with a range of adverse outcomes in pregnancy and can cause long-term disability. Fetal alcohol spectrum disorder (FASD) is an umbrella term to describe a range of effects from prenatal alcohol exposure including fetal alcohol syndrome (FAS). Determining the prevalence of FASD is challenging. This narrative review collates information on the prevalence of FASD in Australia and documents the various methods used for attaining estimates and the limitations of the available data. Birth prevalence of FASD is most commonly measured through clinic-based studies, passive surveillance systems and active case ascertainment. Alcohol use in pregnancy and FAS in Australia is predominantly monitored through passive surveillance systems and under-ascertainment of cases is likely. State- and territory-based studies have reported birth prevalence rates of FAS of between 0.01 and 0.68 per 1000 live births. Prevalence rates of FASD have not been estimated in Australia. As reflected in the international data, Australian studies have found higher rates of FAS among some Indigenous communities. This likely reflects patterns of alcohol use and other socioeconomic risk factors. Under-recognition of FASD reflects incomplete and inconsistent data collections recording alcohol use in pregnancy, lack of awareness among health professionals and a lack of diagnostic and support services. Accurate measurement of FASD prevalence is crucial to inform policy, resource and service development in the areas of health, education, justice and community. There is a need for consensus on the collection and best use of data. [Burns L, Breen C, Bower C, O' Leary C, Elliott EJ.

To examine cancer mortality in a population-based cohort of opioid-dependent persons. New South Wales opioid substitution therapy (OST) program registrants from 1985 to 2005 (n=43,789) were probabilistically linked to the National Death Index. Crude and standardised mortality rates and standardised mortality ratios (SMRs) were calculated. The crude cancer mortality rate increased from 4 to 65 deaths per 100,000 person-years (p trend <0.001). Overall, OST registrants were 1.7 times more likely to die of cancer than the general population (SMR 95% CI 1.4-1.9). Site-specific SMRs were significantly elevated for lung cancer (3.6, 95% CI 2.8-4.6), liver cancer (6.9, 95% CI 4.3-10.5), and anogenital cancers (2.8, 95% CI 1.3-5.3), and significantly reduced for breast cancer (0.4, 95% CI 0.1-0.9). Cancer is an increasingly important cause of death among OST registrants as they live longer with their dependency. The site-specific excess deaths suggest the role of tobacco, alcohol, and infection with hepatitis C and human papillomavirus. The OST setting may be a useful setting for the delivery of programs aimed at detection of precursor lesions, reducing exposure to established carcinogens, and treatment for those with HCV infection. Such targeted steps are likely to reduce the future cancer burden in this population.

Limited research data exists on the prevalence, and characteristics associated with parental alcohol use, particularly in Australia. This study aims to examine the drinking patterns of Australian parents, and to determine whether the drinking pattern differs by family type. The characteristics associated with regular parental alcohol use were also assessed. Data from a representative sample of 23,356 Australians were analysed from the 2007 National Drug Strategy Household Survey. The study found that parents were less likely to drink at levels defined as risky. Additionally, single mothers were more likely to report monthly and weekly binge drinking, compared to other mothers. Four predictors of risky parental alcohol use were identified: male; a current tobacco smoker; reporting higher levels of psychological distress; and lower levels of education. Although this study found that parents were less likely to consume alcohol at risky levels, population estimates suggest a considerable number of Australian children live in households where risky parental alcohol use occurs. This study provides the first step to extending the knowledge base on the prevalence of parental alcohol use which will help to inform public health policy and early intervention programs.

To examine the obstetric and perinatal outcomes for women with a drug-related hospital admission during pregnancy. Antenatal and birth admissions to New South Wales (NSW) hospitals from the NSW Inpatient Statistics Collection were linked to birth information from the NSW Midwives Data Collection over a 5-year period (1998-2002). Birth admissions were flagged as positive for drug use where a birth admission or any pregnancy admission for that birth involved an opioid, cannabis or stimulant-related International Classification of Diseases version 10 Australian modification (ICD-10AM) code. A total of 416 834 live births were analysed over a 5-year period (1998-2002). Of these, 1974 pregnancies had an opioid ICD-10AM diagnosis recorded, 552 a stimulant-related ICD-10AM and 2172 a cannabis ICD-10AM diagnosis. Births in each of the drug groups were to women who were younger, had a higher number of previous pregnancies, were indigenous, smoked heavily and were not privately insured. These women also presented later in their pregnancy to antenatal services and were more likely to arrive at hospital unbooked. Neonates born to women in each of the drug groups were more likely to be premature and were admitted to neonatal intensive care and special care nursery more often, with neonates born to women in the opioid group admitted most often. Linked population level administrative data is a powerful method for examining the maternal and neonatal outcomes associated with the use of specific illicit drugs during pregnancy.
