A rapid review of the evidence on models of service delivery for correctional centre-based mothers and children's units: does our approach need to change?

BACKGROUND: Incarcerated mothers are a marginalised group who experience substantial health and social disadvantage and routinely face disruption of family relationships, including loss of custody of their children. To support the parenting role, mothers and children's units (M&Cs) operate in 97 jurisdictions internationally with approximately 19 000 children reported to be residing with their mothers in custody-based settings. AIM: This rapid review aims to describe the existing evidence regarding the models of service delivery for, and key components of, custodial M&Cs. METHOD: A systematic search was conducted of four electronic databases to identify peer-reviewed literature published from 2010 onwards that reported quantitative and qualitative primary studies focused on custody-based M&Cs. Extracted data included unit components, admission and eligibility criteria, evaluations and recommendations. RESULTS: Of 3075 records identified, 35 met inclusion criteria. M&Cs accommodation was purpose-built, incorporated elements of domestic life and offered a family-like environment. Specific workforce training in caring for children and M&Cs evaluations were largely absent. Our systematic synthesis generated a list of key components for M&C design and service delivery. These components include timely and transparent access to information and knowledge for women, evaluation of the impact of the prison environment on M&C, and organisational opportunities and limitations. CONCLUSION: The next generation of M&Cs requires evidence-based key components that are implemented systematically and is evaluated. To achieve this, the use of codesign is a proven method for developing tailored programmes. Such units must offer a net benefit to both mothers and their children.

Are custodial-based mothers and children's units evaluated, effective and aligned with a human rights-based approach? - A systematic review of the evidence.

Background: Special considerations are warranted for incarcerated mothers and their children, as both experience substantial health and social disadvantage. Children residing in custodial settings are at risk of not having access to the equivalence of education, healthcare and socialisation commensurate to that of children living in the community. This systematic review describes the existing evidence regarding underpinning theories, accessibility, and the effectiveness of custody-based Mothers and children's units (M&Cs) globally. Methods: A systematic database search was conducted on May 1, 2023, of PsycINFO, Scopus, Sociology Ultimate and Web of Science (January 1, 2010, and May 1, 2023). Findings: Our systematic synthesis reveals evidence gaps related to best practice guidelines that align with a human right-based approach, and evaluations of the impact of the prison environment on mothers and their children. Interpretation: These findings support re-design of M&Cs using co-design to develop units that are evidence-based, robustly evaluated, and underpinned by the 'best interest of the child'. Funding: This systematic review was conducted as part of a broader review into M&C programs commissioned and funded by Corrective Services NSW, Australia (CSNSW), a division of the Department of Communities and Justice, as part of the NSW Premier's Priority to Reduce Recidivism within the Women as Parents workstream. No funding was received for this review.

Pregnancy-associated gynecological cancer in New South Wales, Australia 1994-2013: A population-based historical cohort study.

INTRODUCTION: Pregnancy-associated gynecological cancer (PAGC) refers to cancers of the ovary, uterus, fallopian tube, cervix, vagina, and vulva diagnosed during pregnancy or within 12 months postpartum. We aimed to describe the incidence of, and perinatal outcomes associated with, invasive pregnancy-associated gynecological cancer. MATERIAL AND METHODS: We conducted a population-based historical cohort study using linked data from New South Wales, Australia. We included all women who gave birth between 1994 and 2013, with a follow-up period extending to September 30, 2018. Three groups were analyzed: a gestational PAGC group (women diagnosed during pregnancy), a postpartum PAGC group (women diagnosed within 1 year of giving birth), and a control group (women with control diagnosis during pregnancy or within 1 year of giving birth). We used generalized estimation equations to compare perinatal outcomes between study groups. RESULTS: There were 1 786 137 deliveries during the study period; 70 women were diagnosed with gestational PAGC and 191 with postpartum PAGC. The incidence of PAGC was 14.6/100 000 deliveries and did not change during the study period. Women with gestational PAGC (adjusted odds ratio [aAOR] 6.81, 95% confidence interval [CI] 2.97-15.62) and with postpartum PAGC (aOR 2.65, 95% CI 1.25-5.61) had significantly increased odds of a severe maternal morbidity outcome compared with the control group. Babies born to women with gestational PAGC were more likely to be born preterm (aOR 3.11, 95% CI 1.47-6.59) and were at increased odds of severe neonatal complications (aOR 3.47, 95% CI 1.45-8.31) compared with babies born to women without PAC. CONCLUSIONS: The incidence of PAGC has not increased over time perhaps reflecting, in part, the effectiveness of cervical screening and early impacts of human papillomavirus vaccination programs in Australia. The higher rate of preterm birth among the gestational PAGC group is associated with adverse outcomes in babies born to these women.

Effects of the Connections program on return-to-custody, mortality and treatment uptake among people with a history of opioid use: Retrospective cohort study in an Australian prison system.

BACKGROUND AND AIMS: Connections is a voluntary health program that facilitates access to opioid agonist treatment (OAT) and social services for people with opioid use exiting prison. This study aimed to measure the effectiveness of Connections in reducing recidivism and improving health outcomes for people with a history of opioid use on leaving prison. DESIGN: Retrospective cohort study with quasi-random allocation to the program. SETTING: Public adult prisons in New South Wales, Australia, 2008-2015. PARTICIPANTS: Adults released from custody with a history of opioid use. Of 5549 eligible releasees, 3973 were allocated to Connections and 1576 to treatment-as-usual. MEASUREMENTS: Outcomes were return-to-custody, all-cause mortality, and OAT participation. FINDINGS: Regression analyses on an intention-to-treat basis, and adjusting for baseline propensity scores, comparing patients allocated to Connections versus treatment-as-usual showed no difference in rates of return-to-custody within 2 years (hazard ratio [HR]: 1.01; 95% confidence interval [CI]: 0.92 -1.12). Patients allocated to the Connections program were more likely to access OAT (odds ratio [OR]: 1.21; 95% CI: 1.06-1.39) and had lower mortality within 28 days of release (0.25% vs. 0.66%; HR: 0.38; 95% CI: 0.14-1.03). Differences in mortality did not persist beyond 28 days. Subgroup analyses showed that allocation to Connections was associated with higher risk of return-to-custody within 28 days for Aboriginal and/or Torres Strait Islander (Indigenous) and female releasees. CONCLUSIONS: The Connections program for people with opioid use exiting prison did not reduce the likelihood of return-to-custody but did facilitate opioid agonist treatment participation on release from prison.

Developing best practice principles for the provision of programs and services to people transitioning from custody to the community: study protocol for a modified Delphi consensus exercise.

INTRODUCTION: There is a lack of standard nomenclature and a limited understanding of programmes and services delivered to people in prisons as they transition into the community to support their integration and reduce reoffending related risk factors. The aim of this paper is to outline the protocol for a modified Delphi study designed to develop expert consensus on the nomenclature and best-practice principles of programmes and services for people transitioning from prison into the community. METHODS AND ANALYSIS: An online, two-phase modified Delphi process will be conducted to develop an expert consensus on nomenclature and the best-practice principles for these programmes. In the preparatory phase, a questionnaire was developed comprising a list of potential best-practice statements identified from a systematic literature search. Subsequently, a heterogeneous sample of experts including service providers, Community and Justice Services, Not for Profits, First Nations stakeholders, those with lived experience, researchers and healthcare providers will participate in the consensus building phase (online survey rounds and online meeting) to achieve consensus on nomenclature and best-practice principles. Participants will indicate, via Likert scale, to what extent they agree with nomenclature and best-practice statements. If at least 80% of the experts agree to a term or statement (indicated via Likert scale), it will be included in a final list of nomenclature and best-practice statements. Statements will be excluded if 80% experts disagree. Nomenclature and statements not meeting positive or negative consensus will be explored in a facilitated online meeting. Approval from experts will be sought on the final list of nomenclature and best-practice statements. ETHICS AND DISSEMINATION: Ethical approval has been received from the Justice Health and Forensic Mental Health Network Human Research Ethics Committee, the Aboriginal Health and Medical Research Council Human Research Ethics Committee, the Corrective Services New South Wales Ethics Committee and the University of Newcastle Human Research Ethics Committee. The results will be disseminated via peer-reviewed publication.

Pregnancy associated cancer, timing of birth and clinical decision making-a NSW data linkage study.

BACKGROUND: The incidence of pregnancy-associated cancer (PAC), comprising cancer diagnosed during pregnancy or within one year postpartum, is increasing. We investigated the obstetric management and outcomes of women with PAC and their babies. METHODS: A population-based observational study of all women who gave birth between 1994 and 2013 in New South Wales, Australia. Women were stratified into three groups: those diagnosed during pregnancy (gestational cancer group), those diagnosed within one year of giving birth (postpartum cancer group), and a no-PAC group. Generalized estimating equations were used to examine the association between PAC and adverse maternal and neonatal outcomes. RESULTS: One million seven hundred eighty-eight thousand four hundred fifty-onepregnancies were included-601 women (614 babies) were in the gestational cancer group, 1772 women (1816 babies) in the postpartum cancer group, and 1,786,078 women (1,813,292 babies) in the no-PAC group. The overall crude incidence of PAC was 132.7/100,000 women giving birth. The incidence of PAC increased significantly over the twenty-year study period from 93.5/100,000 in 1994 to 162.5/100,000 in 2013 (2.7% increase per year, 95% CI 1.9 - 3.4%, p-value < 0.001). This increase was independent of maternal age. The odds of serious maternal complications (such as acute abdomen, acute renal failure, and hysterectomy) were significantly higher in the gestational cancer group (adjusted odds ratio (AOR) 5.07, 95% CI 3.72 - 6.90) and the postpartum cancer group (AOR 1.55, 95% CI 1.16 - 2.09). There was no increased risk of perinatal mortality in babies born to women with PAC. However, babies of women with gestational cancer (AOR 8.96, 95% CI 6.96 - 11.53) or postpartum cancer (AOR 1.36, 95% CI 1.05 - 1.81) were more likely to be planned preterm birth. Furthermore, babies of women with gestational cancer had increased odds of a severe neonatal adverse outcome (AOR 3.13, 95% CI 2.52 - 4.35). CONCLUSION: Women with PAC are more likely to have serious maternal complications. While their babies are not at increased risk of perinatal mortality, they are more likely to experience poorer perinatal outcomes associated with preterm birth. The higher rate of birth intervention among women with gestational cancers reflects the complexity of clinical decision-making in this context.

Evaluation of a new medical retrieval and primary health care advice model in Central Australia: Results of pre- and post-implementation surveys.

INTRODUCTION: In February 2018 the Remote Medical Practitioner (RMP)-led telehealth model for providing both primary care advice and aeromedical retrievals in Central Australia was replaced by the Medical Retrieval and Consultation Centre (MRaCC) and Remote Outreach Consultation Centre (ROCC). In this new model, specialists with advanced critical care skills provide telehealth consultations for emergencies 24/7 and afterhours primary care advice (MRaCC) while RMPs (general practitioners) provide primary care telehealth advice in business hours via the separate ROCC. OBJECTIVE: To evaluate changes in clinicians' perceptions of efficiency and timeliness of the new (MRaCC) and (ROCC) model in Central Australia. DESIGN: There were 103 and 72 respondents, respectively, to pre- and post-implementation surveys of remote clinicians and specialist staff. FINDINGS: Both emergency and primary care aspects of telehealth support were perceived as being significantly more timely and efficient under the newly introduced MRaCC/ROCC model. Importantly, health professionals in remote community were more likely to feel that their access to clinical support during emergencies was consistent and immediately available. DISCUSSION: Respondents consistently perceived the new MRaCC/ROCC model more favourably than the previous RMP-led model, suggesting that there are benefits to having separate referral streams for telehealth advice for primary health care and emergencies, and staffing the emergency stream with specialists with advanced critical care skills. CONCLUSION: Given the paucity of literature about optimal models for providing pre-hospital medical care to remote residents, the findings have substantial local, national and international relevance and implications, particularly in similar geographically large countries, with low population density.

Perinatal outcomes of women with gestational breast cancer in Australia and New Zealand: A prospective population-based study.

OBJECTIVE: To determine the epidemiology, clinical management, and outcomes of women with gestational breast cancer (GBC). METHODS: A population-based prospective cohort study was conducted in Australia and New Zealand between 2013 and 2014 using the Australasian Maternity Outcomes Surveillance System (AMOSS). Women who gave birth with a primary diagnosis of breast cancer during pregnancy were included. Data were collected on demographic and pregnancy factors, GBC diagnosis, obstetric and cancer management, and perinatal outcomes. The main outcome measures were preterm birth, maternal complications, breastfeeding, and death. RESULTS: Forty women with GBC (incidence 7.5/100 000 women giving birth) gave birth to 40 live-born babies. Thirty-three (82.5%) women had breast symptoms at diagnosis. Of 27 women diagnosed before 30 weeks' gestation, 85% had breast surgery and 67% had systemic therapy during pregnancy. In contrast, all 13 women diagnosed from 30 weeks had their cancer management delayed until postdelivery. There were 17 preterm deliveries; 15 were planned. Postpartum complications included the following: hemorrhage (n = 4), laparotomy (n = 1), and thrombocytopenia (n = 1). There was one late maternal death. Eighteen (45.0%) women initiated breastfeeding, including 12 of 23 women who had antenatal breast surgery. There were no perinatal deaths or congenital malformations, but 42.5% of babies were preterm, and 32.5% were admitted for higher-level neonatal care. CONCLUSIONS: Gestational breast cancer diagnosed before 30 weeks' gestation was associated with surgical and systemic cancer care during pregnancy and planned preterm birth. In contrast, cancer treatment was deferred to postdelivery for women diagnosed from 30 weeks, reflecting the complexity of managing expectant mothers with GBC in multidisciplinary care settings.

The Spectrum, Severity and Outcomes of Rheumatic Mitral Valve Disease in Pregnant Women in Australia and New Zealand.

BACKGROUND: Rheumatic heart disease (RHD) poses significant perinatal risks. We aimed to describe the spectrum, severity and outcomes of rheumatic mitral valve disease in pregnancy in Australia and New Zealand. METHODS: A prospective, population-based cohort study of pregnant women with RHD recruited 2013-14 through the hospital-based Australasian Maternity Outcomes Surveillance System. Outcome measures included maternal and perinatal morbidity and mortality. Univariable and multivariable logistic regression analyses were undertaken to test for predictors of adverse maternal and perinatal outcomes. RESULTS: Of 274 pregnant women identified with RHD, 124 (45.3%) had mitral stenosis (MS) and 150 (54.7%) had isolated mitral regurgitation (MR). One woman with mild MS/moderate MR died. There were six (2.2%) stillbirths and two (0.7%) neonatal deaths. Babies born to women with MS were twice as likely to be small-for-gestational-age (22.7% vs 11.4%, p=0.013). In women with MS, use of cardiac medication (AOR 7.42) and having severe stenosis (AOR 16.35) were independently associated with adverse cardiac outcomes, while New York Heart Association (NYHA) class >1 (AOR 3.94) was an independent predictor of adverse perinatal events. In women with isolated MR, use of cardiac medications (AOR 7.03) and use of anticoagulants (AOR 6.05) were independently associated with adverse cardiac outcomes. CONCLUSIONS: Careful monitoring and specialist care for women with RHD in pregnancy is required, particularly for women with severe MS, those on cardiac medication, and those on anticoagulation, as these are associated with increased risk of adverse maternal cardiac outcomes. In the context of pregnancy, contraception and preconception planning are important for young women diagnosed with RHD.

The needs and experiences of mothers while in prison and post-release: a rapid review and thematic synthesis.

BACKGROUND: Women in prison are a vulnerable group, often with a history of abuse, out-of-home care, mental health problems and unemployment. Many are mothers when they become involved in the criminal justice system and their gender and parenting related needs are often not considered. The aim of this rapid review was to thematically synthesize the existing research on the needs and experiences of mothers while in, and following release from, prison in Australia. METHODS: We conducted a rapid systematic search of electronic databases, search engines, the websites of key agencies, and contacted key agencies and researchers. RESULTS: Twenty-two publications from 12 studies met the inclusion criteria and were thematically synthesized in relation to the mothers, their children, family and community, and systems and services which mothers had contact with. We found that mothers in prison have a history of disadvantage which is perpetuated by the trauma of imprisonment. Release from prison is a particularly challenging time for mothers. In relation to their children, the included studies showed that the imprisonment of mothers impacts their maternal identity and role and disrupts the mother-child relationship. Specific strategies are needed to maintain the mother-child relationship, and to ensure the needs and rights of the child are met. In relation to family and community, we found that although family and social support is an important need of women in prison, such support may not be available. Moreover, the stigma associated with having been in prison is a significant barrier to transitions into the community, including finding employment and housing. In relation to systems and services, although limited services exist to support women in prison and on release, these often do not consider the parenting role. Evaluations of parenting programs in prison found them to be acceptable and beneficial to participants but barriers to access limit the number of women who can participate. CONCLUSION: Mothers have gender- and parenting-specific needs which should be considered in planning for corrective services in Australia. Any service redesign must place the woman and her children at the centre of the service.

Outcomes of Echocardiography-Detected Rheumatic Heart Disease: Validating a Simplified Score in Cohorts From Different Countries.

Background The natural history of latent rheumatic heart disease (RHD) detected by echocardiography remains unclear. We aimed to assess the accuracy of a simplified score based on the 2012 World Heart Federation criteria in predicting mid-term RHD echocardiography outcomes in children from 4 different countries. Methods and Results Patient-level baseline and follow-up data of children with latent RHD from 4 countries (Australia, n=62; Brazil, n=197; Malawi, n=40; New Zealand, n=94) were combined. A simplified echocardiographic scoring system previously developed from Brazilian and Ugandan cohorts, consisting of 5 point-based variables with respective weights, was applied: mitral valveanterior leaflet thickening (weight=3), excessive leaflettip motion (3), regurgitation jet length ≥2 cm (6), aortic valvefocal thickening (4), and any regurgitation (5). Unfavorable outcome was defined as worsening diagnostic category, persistent definite RHD or development/worsening of valve regurgitation/stenosis. The score model was updated using methods for recalibration. 393 patients (314 borderline, 79 definite RHD) with median follow-up of 36 (interquartile range, 25-48) months were included. Median age was 14 (interquartile range, 11-16) years and secondary prophylaxis was prescribed to 16%. The echocardiographic score model applied to this external population showed significant association with unfavorable outcome (hazard ratio, 1.10; 95% CI, 1.04-1.16; P=0.001). Unfavorable outcome rates in low (≤5 points), intermediate (6-9), and high-risk (≥10) children at 3-year follow-up were 14.3%, 20.8%, and 38.5% respectively (P<0.001). The updated score model showed good performance in predicting unfavorable outcome. Conclusions The echocardiographic score model for predicting RHD outcome was updated and validated for different latent RHD populations. It has potential utility in the clinical and screening setting for risk stratification of latent RHD.

Gestational breast cancer in New South Wales: A population-based linkage study of incidence, management, and outcomes.

BACKGROUND: The incidence of gestational breast cancer (GBC) is increasing in high-income countries. Our study aimed to examine the epidemiology, management and outcomes of women with GBC in New South Wales (NSW), Australia. METHODS: A retrospective cohort study using linked data from three NSW datasets. The study group comprised women giving birth with a first-time diagnosis of GBC while the comparison group comprised women giving birth without any type of cancer. Outcome measures included incidence of GBC, maternal morbidities, obstetric management, neonatal mortality, and preterm birth. RESULTS: Between 1994 and 2013, 122 women with GBC gave birth in NSW (crude incidence 6.8/ 100,000, 95%CI: 5.6-8.0). Women aged ≥35 years had higher odds of GBC (adjusted odds ratio (AOR) 6.09, 95%CI 4.02-9.2) than younger women. Women with GBC were more likely to give birth by labour induction or pre-labour CS compared to women with no cancer (AOR 4.8, 95%CI: 2.96-7.79). Among women who gave birth by labour induction or pre-labour CS, the preterm birth rate was higher for women with GBC than for women with no cancer (52% vs 7%; AOR 17.5, 95%CI: 11.3-27.3). However, among women with GBC, preterm birth rate did not differ significantly by timing of diagnosis or cancer stage. Babies born to women with GBC were more likely to be preterm (AOR 12.93, 95%CI 8.97-18.64), low birthweight (AOR 8.88, 95%CI 5.87-13.43) or admitted to higher care (AOR 3.99, 95%CI 2.76-5.76) than babies born to women with no cancer. CONCLUSION: Women aged ≥35 years are at increased risk of GBC. There is a high rate of preterm birth among women with GBC, which is not associated with timing of diagnosis or cancer stage. Most births followed induction of labour or pre-labour CS, with no major short term neonatal morbidity.

Impact of an integrated diabetes service involving specialist outreach and primary health care on risk factors for micro- and macrovascular diabetes complications in remote Indigenous communities in Australia.

OBJECTIVE: To determine the impact of an integrated diabetes service involving specialist outreach and primary health care teams on risk factors for micro- and macrovascular diabetes complications in three remote Indigenous Australian communities over a 12-month period. DESIGN: Quantitative, retrospective evaluation. SETTING: Primary health care clinics in remote Indigenous communities in Australia. PARTICIPANTS: One-hundred-and-twenty-four adults (including 123 Indigenous Australians; 76.6% female) with diabetes living in remote communities. MAIN OUTCOME MEASURES: Glycosylated haemoglobin, lipid profile, estimated glomerular filtration rate, urinary albumin : creatinine ratio and blood pressure. RESULTS: Diabetes prevalence in the three communities was high, at 32.8%. A total of 124 patients reviewed by the outreach service had a median consultation rate of 1.0 by an endocrinologist and 0.9 by a diabetes nurse educator over the 12-month period. Diabetes care plans were made in collaboration with local primary health care services, which also provided patients with diabetes care between outreach team visits. A significant reduction was seen in median (interquartile range) glycosylated haemoglobin from baseline to 12 months. Median (interquartile range) total cholesterol was also reduced. The number of patients prescribed glucagon-like peptide-1 analogues and dipeptidyl peptidase-4 inhibitors increased over the 12 months and an increase in the number of patients prescribed insulin trended towards statistical significance. CONCLUSION: A collaborative health care approach to deliver diabetes care to remote Indigenous Australian communities was associated with an improvement in glycosylated haemoglobin and total cholesterol, both important risk factors, respectively, for micro- and macrovascular diabetes complications.

Bronchiectasis in indigenous and non-indigenous residents of Australia and New Zealand.

BACKGROUND AND OBJECTIVE: Bronchiectasis not associated with cystic fibrosis is an increasingly recognized chronic lung disease. In Oceania, indigenous populations experience a disproportionately high burden of disease. We aimed to describe the natural history of bronchiectasis and identify risk factors associated with premature mortality within a cohort of Aboriginal Australians, New Zealand Maori and Pacific Islanders, and non-indigenous Australians and New Zealanders. METHODS: This was a retrospective cohort study of bronchiectasis patients aged >15 years at three hospitals: Alice Springs Hospital and Monash Medical Centre in Australia, and Middlemore Hospital in New Zealand. Data included demographics, ethnicity, sputum microbiology, radiology, spirometry, hospitalization and survival over 5 years of follow-up. RESULTS: Aboriginal Australians were significantly younger and died at a significantly younger age than other groups. Age- and sex-adjusted all-cause mortality was higher for Aboriginal Australians (hazard ratio (HR): 3.9), and respiratory-related mortality was higher for both Aboriginal Australians (HR: 4.3) and Maori and Pacific Islander people (HR: 1.7). Hospitalization was common: Aboriginal Australians had 2.9 admissions/person-year and 16.9 days in hospital/person-year. Despite Aboriginal Australians having poorer prognosis, calculation of the FACED score suggested milder disease in this group. Sputum microbiology varied with Aspergillus fumigatus more often isolated from non-indigenous patients. Airflow obstruction was common (66.9%) but not invariable. CONCLUSIONS: Bronchiectasis is not one disease. It has a significant impact on healthcare utilization and survival. Differences between populations are likely to relate to differing aetiologies and understanding the drivers of bronchiectasis in disadvantaged populations will be key.

Better Indigenous Risk stratification for Cardiac Health study (BIRCH) protocol: rationale and design of a cross-sectional and prospective cohort study to identify novel cardiovascular risk indicators in Aboriginal Australian and Torres Strait Islander adults.

BACKGROUND: Of the estimated 10-11 year life expectancy gap between Indigenous (Aboriginal and Torres Strait Islander people) and non-Indigenous Australians, approximately one quarter is attributable to cardiovascular disease (CVD). Risk prediction of CVD is imperfect, but particularly limited for Indigenous Australians. The BIRCH (Better Indigenous Risk stratification for Cardiac Health) project aims to identify and assess existing and novel markers of early disease and risk in Indigenous Australians to optimise health outcomes in this disadvantaged population. It further aims to determine whether these markers are relevant in non-Indigenous Australians. METHODS/DESIGN: BIRCH is a cross-sectional and prospective cohort study of Indigenous and non-Indigenous Australian adults (≥ 18 years) living in remote, regional and urban locations. Participants will be assessed for CVD risk factors, left ventricular mass and strain via echocardiography, sleep disordered breathing and quality via home-based polysomnography or actigraphy respectively, and plasma lipidomic profiles via mass spectrometry. Outcome data will comprise CVD events and death over a period of five years. DISCUSSION: Results of BIRCH may increase understanding regarding the factors underlying the increased burden of CVD in Indigenous Australians in this setting. Further, it may identify novel markers of early disease and risk to inform the development of more accurate prediction equations. Better identification of at-risk individuals will promote more effective primary and secondary preventive initiatives to reduce Indigenous Australian health disadvantage.

Sharing success - understanding barriers and enablers to secondary prophylaxis delivery for rheumatic fever and rheumatic heart disease.

BACKGROUND: Rheumatic fever (RF) and rheumatic heart disease (RHD) cause considerable morbidity and mortality amongst Australian Aboriginal and Torres Strait Islander populations. Secondary antibiotic prophylaxis in the form of 4-weekly benzathine penicillin injections is the mainstay of control programs. Evidence suggests, however, that delivery rates of such prophylaxis are poor. METHODS: This qualitative study used semi-structured interviews with patients, parents/care givers and health professionals, to explore the enablers of and barriers to the uptake of secondary prophylaxis. Data from participant interviews (with 11 patients/carers and 11 health practitioners) conducted in four far north Queensland sites were analyzed using the method of constant comparative analysis. RESULTS: Deficits in registration and recall systems and pain attributed to injections were identified as barriers to secondary prophylaxis uptake. There were also varying perceptions regarding responsibility for ensuring injection delivery. Enablers of secondary prophylaxis uptake included positive patient-healthcare provider relationships, supporting patient autonomy, education of patients, care givers and healthcare providers, and community-based service delivery. CONCLUSION: The study findings provide insights that may facilitate enhancement of secondary prophylaxis delivery systems and thereby improve uptake of secondary prophylaxis for RF/RHD.

Approaches to Improving Adherence to Secondary Prophylaxis for Rheumatic Fever and Rheumatic Heart Disease: A Literature Review with a Global Perspective.

Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) are autoimmune conditions resulting from infection with group A streptococcus. Current management of these conditions includes secondary antibiotic prevention. This comprises regular 3 to 4 weekly long-acting intramuscular benzathine penicillin injections. Secondary antibiotic prevention aims to protect individuals against reinfection with group A streptococcus, thereby preventing recurrent ARF and the risk of further damage to the heart valves. However, utilization of benzathine penicillin can be poor leaving patients at risk of avoidable and progressive heart damage. This review utilizes the Chronic Care Model as a framework to discuss initiatives to enhance the delivery of secondary antibiotic prophylaxis for ARF and RHD. Results from the search strategy utilized revealed that there is limited pertinent published evidence. The evidence that is available suggests that register/recall systems, dedicated health teams for delivery of secondary antibiotic prophylaxis, education about ARF and RHD, linkages with the community (particularly between health services and schools), and strong staff-patient relationships may be important. However, it is difficult to generalize findings from individual studies to other settings and high quality studies are lacking. Although secondary antibiotic prophylaxis is an effective treatment for those with ARF or RHD, the difficulties in implementing effective programs that reduce the burden of ARF and RHD demonstrates the importance of ongoing work in developing and evaluating research translation initiatives.

Are minor echocardiographic changes associated with an increased risk of acute rheumatic fever or progression to rheumatic heart disease?

BACKGROUND: The World Heart Federation criteria for the echocardiographic diagnosis of rheumatic heart disease (RHD) include a category "Borderline" RHD which may represent the earliest evidence of RHD. We aimed to determine the significance of minor heart valve abnormalities, including Borderline RHD, in predicting the future risk of acute rheumatic fever (ARF) or RHD. METHODS: A prospective cohort study of Aboriginal and Torres Strait Islander children aged 8 to 18 years was conducted. Cases comprised children with Borderline RHD or other minor non-specific valvular abnormalities (NSVAs) detected on prior echocardiography. Controls were children with a prior normal echocardiogram. Participants underwent a follow-up echocardiogram 2.5 to 5 years later to assess for progression of valvular changes and development of Definite RHD. Interval diagnoses of ARF were ascertained. RESULTS: There were 442 participants. Cases with Borderline RHD were at significantly greater risk of ARF (incidence rate ratio 8.8, 95% CI 1.4-53.8) and any echocardiographic progression of valve lesions (relative risk 8.19, 95% CI 2.43-27.53) than their Matched Controls. Cases with Borderline RHD were at increased risk of progression to Definite RHD (1 in 6 progressed) as were Cases with NSVAs (1 in 10 progressed). CONCLUSIONS: Children with Borderline RHD had an increased risk of ARF, progression of valvular lesions, and development of Definite RHD. These findings provide support for considering secondary antibiotic prophylaxis or ongoing surveillance echocardiography in high-risk children with Borderline RHD.

Echocardiographic screening for rheumatic heart disease-some answers, but questions remain.

Despite being preventable, rheumatic heart disease (RHD) remains a significant global cause of cardiovascular disease. Echocardiographic screening for early detection of RHD has the potential to enable timely commencement of treatment (secondary prophylaxis) to halt progression to severe valvular disease. However, a number of issues remain to be addressed regarding its feasibility. The natural history of Definite RHD without a prior history of acute rheumatic fever (ARF) and Borderline RHD are both unclear. Even if they are variants of RHD it is not known whether secondary antibiotic prophylaxis will prevent disease progression as it does in "traditionally" diagnosed RHD. False positives can also have a detrimental impact on individuals and their families as well as place substantial burdens on health care systems. Recent research suggests that handheld echocardiography (HAND) may offer a cheaper and more convenient alternative to standard portable echocardiography (STAND) in RHD screening. However, while HAND is sensitive for the detection of Definite RHD, it is less sensitive for Borderline RHD and is relatively poor at detecting mitral stenosis (MS). Given its attendant limited specificity, potential cases detected with HAND would require re-examination by standard echocardiography. For now, echocardiographic screening for RHD should remain a subject of research rather than routine health care.
