Sex differences in acute health service contact after release from prison in Australia: a data linkage study

OBJECTIVES

Women released from prison typically experience worse health outcomes than their male counterparts. We examined sex differences in the patterns, characteristics, and predictors of acute health service contact (AHSC) (i.e. ambulance and/or emergency department use) after release from prison.

STUDY DESIGN

Data linkage study.

METHODS

Baseline survey data from 1307 adults (21% women) within six weeks of expected release from prisons in Queensland, Australia (2008-2010) were linked prospectively with state-wide ambulance and emergency department, correctional, mental health, and death records. Crude and adjusted incidence rates and incidence rate ratios of AHSC were calculated overall and by sex. An Andersen-Gill model was fit to examine whether sex predicted AHSC. The interaction effect between sex and each model covariate was tested.

RESULTS

The crude incidence rates of AHSC after release from prison were 1.4 (95% confidence interval [CI]: 1.3-1.5) and 1·1 (95%CI: 1.1-1.2) per person-year for women and men, respectively. The relationship between perceived physical health-related functioning at the baseline and AHSC was modified by sex (P = 0·039). The relationship between perceived health-related functioning and AHSC also differed among women. Compared to women who perceived their physical health as fair or good at the baseline, women who perceived their physical health as poor were at greater risk of AHSC (hazard ratio = 2.4, 95%CI: 1.4-3·9, P = 0.001) after release from prison.

CONCLUSIONS

Among people released from prison, women's and men's AHSC differs depending on how they perceive their own physical health. The specific needs of women and men must be considered in transitional support policy and planning to improve their health outcomes.

Health literacy strengths and challenges of people in New South Wales prisons: a cross-sectional survey using the Health Literacy Questionnaire (HLQ)

BACKGROUND

Health literacy is an important factor for enabling people to manage their health and live long fulfilling lives. People in prison are frequently from marginalised communities, often out of reach of conventional community based health organisations, and have poorer health outcomes. It is essential to understanding the health literacy profiles of people in prison, and its contribution to the well-established health inequities and outcomes of this population. This study aimed to use a multi-dimensional health literacy measurement tool to describe the strengths and challenges of adults incarcerated in NSW prisons.

METHODS

A cross-sectional survey was conducted for people in prison across 14 publicly operated metropolitan prisons. Data were collected from 471 participants using the Health Literacy Questionnaire (HLQ). Participant characteristics and health conditions were also collected. Data were analysed using descriptive statistics. Effect sizes (ES) for standardised differences in means were used to describe the magnitude of difference between participant characteristic groups.

RESULTS

Participants' median age was 38.0 (range 19 - 91) years. Males comprised 81% of the sample, 21% identified as Aboriginal and/or Torres Strait Islander, and 53% reported a health problem. People in prison had lower scores for all nine HLQ scales when compared to the general Australian population. Small to medium ES were seen for mean differences between most demographic groups. Compared to males, females had lower scores for several of the HLQ scales including 'having sufficient information to manage health' (ES 0.30 [95% Confidence Interval (CI) 0.07, 0.53]), 'ability to actively engage with health care professionals' (ES 0.30 [95% CI 0.06, 0.53]), 'navigating the healthcare system' (ES 0.30 [95% CI 0.06, 0.53]), and, 'ability to find good health information' (ES 0.33 [95% CI 0.10, 0.57]). Differing health literacy scale scores with small to medium ES were found when comparing participants by legal status. Mainly small ES were seen when comparing other participant characteristic groups.

CONCLUSIONS

This study provides insights into the health literacy strengths and challenges for people in NSW prisons. These findings highlight the important role health literacy could have in addressing health disparities in this vulnerable population and can inform prison health services.

Violence-related morbidity among people released from prison in Australia: A data linkage study

INTRODUCTION

People released from prison have an increased risk of morbidity, including from nonfatal violence. We examined the incidence and predictors of violence-related morbidity after release from prison and investigated whether there are differences according to sex and Indigenous status.

METHODS

Baseline data were collected from 1325 people within 6 weeks of release from prisons in Queensland, Australia, between 1 August 2008 and 31 July 2010. Data were linked to state-wide health (ambulance, emergency department and hospital) and prison records, and national death records until 31 July 2012. Predictors were identified using a multivariable Andersen-Gill model. Differences according to sex and Indigenous status were investigated using effect modification.

RESULTS

A total of 225 (18.2%) people experienced 410 violence-related events that were recorded in health records. The incidence was 12.8 per 100 person-years [95% confidence interval (CI) 11.7, 14.1]. Risk factors for violence-related morbidity included diagnosed mental illness [hazard ratio (HR) = 2.0, 95% CI 1.1, 3.8], substance use disorder (HR = 1.6, 95% CI 1.1, 2.3) or dual diagnosis (HR = 3.2, 95% CI 2.2, 4.8); high-risk alcohol use (HR = 2.1, 95% CI 1.5, 2.8); being Indigenous (HR = 1.7, 95% CI 1.2, 2.5); and two or more prison releases (HR = 1.7, 95% CI 1.2, 2.6). Indigenous status modified the risk of violence-related morbidity, with Indigenous men having twice the risk of non-Indigenous men (HR = 1.9, 95% CI 1.3, 2.8).

DISCUSSION AND CONCLUSIONS

Approximately one in five people released from prisons in Queensland experienced violence-related morbidity. Coordinated and continuous mental health and substance use treatment from prison to the community may reduce the risk of violence-related morbidity in this population.

Risky alcohol consumption prior to incarceration: A cross-sectional study of drinking patterns among Australian prison entrants

INTRODUCTION AND AIMS

Risky alcohol consumption is linked to poor health and criminal justice outcomes. This study aims to assess the prevalence and correlates of risky drinking in a sample of recently incarcerated Australians.

DESIGN AND METHODS

Consecutive cross-sectional data were collected from prisoners residing in 19 correctional facilities in six Australian states and territories as part of the National Prison Entrants' Bloodborne Virus and Risk Behaviour Survey Report. The sample consisted of 389 prisoners (339 men, 50 women). Risky alcohol consumption was estimated using the Alcohol Use Disorders Identification Test-Condensed questionnaire, with a cut-off score of ≥6. Potential correlates of risky alcohol consumption were assessed utilising univariate and multivariate analyses.

RESULTS

Over one-third (34.5%) of prisoners who were screened met the criteria for risky alcohol consumption. The five factors found to be independently and positively associated with risky alcohol consumption were Aboriginal and Torres Strait Islander (Indigenous) status, incarceration in prison in the Northern Territory, heavy tobacco use, cannabis use and abstinence from drugs in the 4 weeks prior to incarceration. Additionally, risky alcohol consumption was associated with current or past hepatitis B or hepatitis C infection.

DISCUSSION AND CONCLUSIONS

The findings highlight that risky alcohol consumption is common among prisoners across Australia. This is known to be associated with adverse health outcomes and re-offending, suggesting a need for alcohol interventions targeting prisoners.
