Repurposing antibiotic resistance surveillance data to support treatment of recurrent infections in a remote setting.

In northern Australia, a region with limited access to healthcare and a substantial population living remotely, antibiotic resistance adds to the complexity of treating infections. Focussing on Escherichia coli urinary tract infections (UTIs) and Staphylococcus aureus skin & soft tissue infections (SSTIs) captured by a northern Australian antibiotic resistance surveillance system, we used logistic regression to investigate predictors of a subsequent resistant isolate during the same infection episode. We also investigated predictors of recurrent infection.

Contribution of socio-economic factors in the spread of antimicrobial resistant infections in Australian primary healthcare clinics.

Objectives: To effectively contain antimicrobial-resistant (AMR) infections, we must better understand the social determinates of health that contribute to transmission and spread of infections.

Methods: We used clinical data from patients attending primary healthcare clinics across three jurisdictions of Australia (2007-2019). Escherichia coli (E.

Antibiotic resistance in uropathogens across northern Australia 2007-20 and impact on treatment guidelines.

Background: Urinary tract infections are common and are increasingly resistant to antibiotic therapy. Northern Australia is a sparsely populated region with limited access to healthcare, a relatively high burden of disease, a substantial regional and remote population, and high rates of antibiotic resistance in skin pathogens.

Objectives: To explore trends in antibiotic resistance for common uropathogens and in northern Australia, and how these relate to current treatment guidelines in the community and hospital settings.

Estimation of the force of infection and infectious period of skin sores in remote Australian communities using interval-censored data.

Prevalence of impetigo (skin sores) remains high in remote Australian Aboriginal communities, Fiji, and other areas of socio-economic disadvantage. Skin sore infections, driven primarily in these settings by Group A Streptococcus (GAS) contribute substantially to the disease burden in these areas. Despite this, estimates for the force of infection, infectious period and basic reproductive ratio-all necessary for the construction of dynamic transmission models-have not been obtained.

Antimicrobial stewardship in remote primary healthcare across northern Australia.

Background: The high burden of infectious disease and associated antimicrobial use likely contribute to the emergence of antimicrobial resistance in remote Australian Aboriginal communities. We aimed to develop and apply context-specific tools to audit antimicrobial use in the remote primary healthcare setting.

Methods: We adapted the General Practice version of the National Antimicrobial Prescribing Survey (GP NAPS) tool to audit antimicrobial use over 2-3 weeks in 15 remote primary healthcare clinics across the Kimberley region of Western Australia (03/2018-06/2018), Top End of the Northern Territory (08/2017-09/2017) and far north Queensland (05/2018-06/2018).

High burden of infectious disease and antibiotic use in early life in Australian Aboriginal communities.

Objective: To quantify the childhood infectious disease burden and antibiotic use in the Northern Territory's East Arnhem region through synthesis and analysis of historical data resources.

Methods: We combined primary health clinic data originally reported in three separate publications stemming from the East Arnhem Healthy Skin Project (Jan-01 to Sep-07). Common statistical techniques were used to explore the prevalence of infectious conditions and the seasonality of infections, and to measure rates of antibiotic use.

Scabies and risk of skin sores in remote Australian Aboriginal communities: A self-controlled case series study.

Background: Skin sores caused by Group A streptococcus (GAS) infection are a major public health problem in remote Aboriginal communities. Skin sores are often associated with scabies, which is evident in scabies intervention programs where a significant reduction of skin sores is seen after focusing solely on scabies control. Our study quantifies the strength of association between skin sores and scabies among Aboriginal children from the East Arnhem region in the Northern Territory.
