ItemEmergency health service contact and reincarceration after release from prison: A prospective cohort study(WILEY, 2019-04)BACKGROUND: Adults released from prison often have complex health needs. They are at high risk of poor health outcomes and reincarceration, with health service use unlikely to be planned. AIMS/HYPOTHESES: To determine the incidence of emergency health service (EHS) use, ambulance attendance and/or emergency department presentation, among 1,181 adults released from Australian prisons. We hypothesised that EHS contact would be associated with increased reincarceration risk. METHODS: Baseline surveys were conducted within 6 weeks before release. Postrelease EHS contacts and reincarceration were identified through prospective data linkage. For each participant, EHS contacts within a 24-hour period were combined to make an episode. We used Cox proportional hazards regression to examine the relationship between EHS episodes and reincarceration, controlling for covariates. RESULTS: More than half (53.3%) of participants had at least one EHS contact over a median of 25.6-month follow-up. In adjusted analyses, compared to those with no EHS contacts, the hazard of reincarceration was greater for participants who had one to three EHS episodes (hazard ratio [HR] = 1.84; 95% confidence interval [CI] [1.48, 2.29]) or four or more (HR = 2.35; 95% CI [1.67, 3.29]). CONCLUSIONS/IMPLICATIONS FOR PRACTICE: Emergency department attendance by people with a history of imprisonment may be indicative of wider decompensation. Improved management of such patients may improve health outcomes and have collateral benefits for reducing reincarceration.

ItemCost-utility analysis of low-intensity case management to increase contact with health services among ex-prisoners in Australia(BMJ PUBLISHING GROUP, 2018-08)OBJECTIVES: The economic burden of incarceration is substantial in Australia. People released from prison are at high risk of poor health and this is an important predictor of recidivism. The 'Passports Study' was a randomised controlled trial of an intervention designed to increase health service utilisation after release from prison. The aim of this study is to conduct a cost-utility analysis of this transitional programme. SETTING: Australia DESIGN: A hybrid simulation model was developed to estimate the changes to total economic costs and effectiveness expressed as quality-adjusted life-years (QALYs) from the adoption of the 'Passports' intervention compared with the control group. Model parameters were informed by linked data from Queensland Corrective Services, Medicare, Pharmaceutical Benefits Scheme, Queensland Hospital Admission Patient Data Collection, Emergency Department Information System and National Death Index. Health-related quality of life was measured using the Short-Form 8 Health Survey (SF-8). The primary outcomes were the costs and estimated QALYs associated with the intervention group and the control group. Probabilistic sensitivity analysis was conducted to test parameter uncertainties. RESULTS: Compared with the control group where no attempt was made to encourage health service utilisation, an average participant in the intervention group incurred an extra cost of AUD 1790 and experienced slightly reduced QALYs, which indicated that the intervention was dominated in the baseline analysis. Probabilistic sensitivity analysis revealed that the transitional programme had a low probability of being cost-effective with the outcome measures selected. CONCLUSION: The findings of this study do not provide economic evidence to support the widespread adoption of the Passports intervention. Due to the reductionist nature of the cost-utility approach, it may be that important health-related benefits have been omitted. Another research approach using a wider range of health-related measures might generate different conclusions.

ItemAge-Specific Global Prevalence of Hepatitis B, Hepatitis C, HIV, and Tuberculosis Among Incarcerated People: A Systematic Review(ELSEVIER SCIENCE INC, 2018-03)PURPOSE: This study aims to compare the global prevalence of hepatitis B, hepatitis C, HIV, and tuberculosis in incarcerated adolescents and young adults (AYAs) and older prisoners. METHODS: This study is a systematic review and meta-analysis of studies reporting the age-specific prevalence of each infection in prisoners. We grouped age-specific prevalence estimates into three overlapping age categories: AYA prisoners (<25 years), older prisoners (≥25 years), and mixed category (spanning age 25 years). We used random effects meta-analysis to estimate the relative risk (RR) of each infection in AYAs versus older prisoners. RESULTS: Among 72 studies, there was marked heterogeneity in prevalence estimates among AYA prisoners for all infections: hepatitis B (.4%-25.2%), hepatitis C (.0%-70.6%), HIV (.0%-15.8%), and active tuberculosis (.0%-3.7%). The pooled prevalence of HIV (RR = .39, 95% confidence interval .29-.53, I2 = 79.2%) and hepatitis C (RR = .51, 95% confidence interval .33-.78, I2 = 97.8%) was lower in AYAs than in older prisoners. CONCLUSIONS: The prevalence of HIV and hepatitis C is lower in AYA prisoners than in older prisoners. Despite lower prevalence, acquisition begins early among incarcerated populations. There is an urgent need for targeted, age-appropriate prevention, treatment, and harm reduction measures in and beyond custodial settings to reduce the incidence of infection in these extremely vulnerable young people.

ItemExplaining variation in the burden of child and adolescent tuberculosis(European Respiratory Society, 2019-06)We read with interest the recent publication by Chen et al regarding the burden of notified tuberculosis (TB) among adolescents and young adults in Taiwan[1]. The authors report that 10-24 year olds constituted only 5.2% of all newly diagnosed TB patients in Taiwan from 2005 to 2016, and that this percentage declined from around 6% in 2005 to around 4% in 2016. They contrast these figures with our estimate that young people constitute 17% of all people developing incident TB globally in 2012[2]. There are several factors that explain this apparently large discrepancy.

ItemTuberculosis among children, adolescents and young adults in the Philippines: a surveillance report(WORLD HEALTH ORGANIZATION, REGIONAL OFFICE WESTERN PACIFIC, 2018)The Philippines, a country with a young population, is currently experiencing an intense and persistent tuberculosis epidemic. We analysed patient-based national surveillance data to investigate the epidemiology of reported tuberculosis among children (aged 0-9 years), adolescents (aged 10-19 years) and young adults (aged 20-24 years) to better understand the burden of disease and treatment outcomes in these age groups. Descriptive analyses were performed to assess age-related patterns in notifications and treatment outcomes. Data quality was assessed against international benchmarks at the national and regional levels. Overall, 27.3% of tuberculosis notifications for the Philippines in 2015 pertained to children, adolescents and young adults aged 0-24 years. Treatment outcomes were generally favourable, with 81% of patients being cured or completing treatment. The data quality assessment revealed substantial regional variation in some indicators and suggested potential underdetection of tuberculosis in children aged 0-4 years. Children, adolescents and young adults in the Philippines constitute a substantial proportion of patients in the national tuberculosis surveillance data set. Long-term progress against tuberculosis in the Philippines relies on improving the control of tuberculosis in these key age groups.

ItemIncidence and prevalence of bacteriologically confirmed pulmonary tuberculosis among adolescents and young adults: a systematic review(CAMBRIDGE UNIV PRESS, 2018-06)The burden of tuberculosis (TB) among adolescents and young adults in endemic settings is poorly characterised. This study aimed to review published and unpublished estimates of the incidence and prevalence of bacteriologically confirmed TB among young people aged 10-24 years. We searched PubMed and World Health Organization archives for publications and unpublished data from population-based epidemiologic studies reporting confirmed pulmonary TB among young people, conducted from January 2000 onwards. We identified 27 publications and unpublished data from two national surveys, representing a total of 26 studies in 19 countries. The prevalence of bacteriologically confirmed TB ranged from 45 to 799 per 100 000 in the Asia-Pacific region and from 160 to 462 per 100 000 in African settings. We did not identify any epidemiologic studies of confirmed TB among adolescents living with human immunodeficiency virus (HIV). Many studies were excluded due to absent or inadequately reported age-specific data. Adolescents and young adults living in many endemic settings appear to be at substantial risk of developing active TB. There is a pressing need to improve the routine reporting of age in epidemiologic studies of TB, and to generate high-quality epidemiologic data regarding TB among adolescents living with HIV.

ItemThe incidence of tuberculosis among adolescents and young adults: a global estimate(EUROPEAN RESPIRATORY SOC JOURNALS LTD, 2018-02-01)Historical data show that the risk of tuberculosis increases dramatically during adolescence, and young people face unique challenges in terms of case detection and effective treatment. However, little is known about the burden of tuberculosis among young people in the modern era. This study aimed to provide the first estimates of the global and regional incidence of tuberculosis among young people aged 10-24 years.Using the World Health Organization (WHO) database of tuberculosis notifications for 2012, we estimated the burden of tuberculosis among young people by WHO region. Adjustments were made for incomplete age disaggregation and underreporting, using supplementary data from several countries representing diverse tuberculosis epidemics.We estimate that 1.78 million (uncertainty interval (UI) 1.23-3.00 million) young people developed tuberculosis in 2012, accounting for 17% of all new tuberculosis cases globally. Young people in the WHO South East Asian Region (721 000, UI 473 000-1.35 million) and the WHO African Region (534 000, UI 359 000-912 000) experienced the greatest number of tuberculosis episodes.Young people suffer a considerable burden of tuberculosis. Age-specific burden of disease estimation for this age group is complicated by incomplete age disaggregation of tuberculosis data, highlighting the importance of continued surveillance system strengthening.
