Evaluating a novel model of hepatitis B care, Hep B PAST, in the Northern Territory of Australia: results from a prospective, population-based study.

Background: The Northern Territory (NT) has the highest prevalence of chronic hepatitis B (CHB) in Australia. The Hep B PAST program aims to improve health outcomes for people living with CHB. Methods: This mixed methods study involves First Nations peoples living in the NT. We used participatory action research principles across three steps: 1. Foundation step: establishing hepatitis B virus (HBV) status and linkage to care; 2. Capacity building: training the health workforce; 3. Supported transition to primary healthcare: implementation of the "Hub and Spoke" model and in-language resources. Analysis occurred at three time points: 1. Pre-Hep B PAST (2018); 2. Foundation step (2020); and 3. Completion of Hep B PAST (2023). Evaluation focuses on four key indicators, the number of people: 1) with documented HBV status; 2) diagnosed with CHB; 3) receiving care; and 4) receiving treatment. Findings: Hep B PAST (2018-23) reached 40,555 people. HBV status was documented in 11% (1192/10,853), 79.2% (26,075/32,915) and 90.8% (28,675/31,588) of people at pre-Hep B PAST, foundation step, and completion respectively. An estimated 99.9% (821/822) of people were diagnosed, 86.3% (709/822) engaged in care, and 24.1% (198/822) on antiviral treatment at completion. CHB prevalence in the study population is 2.6%, decreasing from 6.1% to 0.4% in the pre- and post-vaccination cohorts. Interpretation: Hep B PAST is an effective model of care. Partner health services are exceeding elimination targets. This model could enable other countries to enhance the cascade of care and work towards eliminating HBV.

A cluster of acute rheumatic fever cases among Aboriginal Australians in a remote community with high baseline incidence.

OBJECTIVES: We report a cluster of acute rheumatic fever (ARF) cases and the public health response in a high-burden Australian setting. METHODS: The public health unit was notified of an increase in ARF cases in a remote Australian Aboriginal community. A multi-disciplinary group coordinated the response. Household contacts were screened for ARF or group A Streptococcus (GAS) infection by questionnaire and swab collection, offered an echocardiogram if aged 5-20 years, and intramuscular benzathine benzylpenicillin if aged over one year or if less than one year with impetigo. RESULTS: Fifteen definite and seven probable ARF cases were diagnosed in the community in July-December 2014 (all-age incidence of definite ARF: 1,473/100,000). The public health response identified two additional cases of ARF. A total of 81 contacts were screened; GAS was detected in 3/76 (4%) throat swabs and 11/24 (46%) skin swabs. Molecular typing revealed high GAS strain diversity. CONCLUSIONS: The incidence of ARF during this cluster was very high. Carriage and infection with GAS was observed, but no outbreak strain identified. Implications for public health: A national public health guideline has since been developed that includes advice on the investigation of an ARF outbreak/cluster. Sustained efforts with strong community engagement are required to tackle high ARF rates.

Where are they now? The career paths of the Remote Vocational Training Scheme registrars.

BACKGROUND: The Remote Vocational Training Scheme trains doctors in remote communities using distance education and supervision. AIMS: To document the training location, outcomes of training, current location and services provided by program graduates and assess the effectiveness of their training. RESULTS: Twenty-four doctors graduated from the Remote Vocational Training Scheme program. Registrars provided over 44 years of clinical service in very remote areas during training. Of those working in Australia, 17 out of 21 (81%) still work in rural areas and 20 (95%) gained dual qualification of Fellowship of the Australian College of Rural and Remote Medicine and Fellowship of The Royal Australian College of General Practitioners. Registrars evaluated the program as effective preparation for clinical practice. CONCLUSION: The first medical specialist training program in Australia and comparable western countries to use remote supervision achieved its targets of increasing retention of the rural and remote workforce during and after training.
