Management of Chlamydia Cases in Australia (MoCCA) is a National Health and Medical Research Council-funded Partnership Grant that that seeks to address gaps in chlamydia management in Australian general practice. In particular, MoCCA focuses on improving testing for repeat infection within recommended timeframes, improving partner management, and increasing clinician confidence in diagnosing pelvic inflammatory disease (PID).

In the early stages of MoCCA we focused on better understanding the general practice context for chlamydia management. This involved both interviews and surveys with health consumers, general practitioners, and other general practice staff about how chlamydia infections are managed in general practice.

Drawing on these findings, we developed a model of care to support chlamydia management in general practice, which we piloted in general practice clinics in New South Wales and Queensland. The model of care includes our website (which you can find here:, and other resources and strategies for integrating best practice chlamydia management into routine care. All of our resources and strategies are available on our website.

Interested in participating?

We are recruiting general practice clinics to participate in MoCCA. If you are a GP, practice nurse or practice manager and think your practice might be interested in participating, please contact us at We are currently recruiting clinics to participate in the MoCCA study for a period of up to 18 months. Clinics will be asked to implement interventions designed to strengthen management of genital chlamydia infections. These interventions focus on partner management, retesting within recommended timeframes, and increasing clinician confidence in diagnosing PID.  If you are a GP, practice nurse or practice manager and think your practice might be interested in participating, please contact us at or head to our website for more information:

Thank you to all who have participated in the project so far.

Background to the project:

Chlamydia trachomatis (‘chlamydia’) is the most commonly diagnosed bacterial sexually transmitted infection (STI) worldwide and can have serious complications - 17% of cases will lead to pelvic inflammatory disease (PID) equating to over 30,000 cases per year in Australia. The risk of PID increases up to 4-fold in women who become reinfected, with very high reinfection rates among women in Australia (22% per year). Chlamydia can also lead to ectopic pregnancy and tubal factor infertility.

In Australia over 80% of chlamydia cases are diagnosed in general practice, making it a critical sector for chlamydia control. Our past research the Australian Chlamydia Control Effectiveness Pilot (ACCEPt) has shown that chlamydia control policy must prioritise case management. through effective partner management to prevent reinfection, timely re-testing after treatment to detect re-infection earlier and improved detection of PID.

Australian researchers have been at the forefront of research to identify effective innovative interventions for partner management, chlamydia retesting and PID management in sexual health and family planning clinics.  What is needed now, is to translate these interventions into general practice where the majority of chlamydia infections are diagnosed and managed.

The aim of the project is to reduce the burden of chlamydia infection by scaling up an integrated model of chlamydia case management in general practice. The project objectives are:
*Develop and refine an integrated model of chlamydia case management for implementation.
*Evaluate the clinical uptake, impact and cost-effectiveness of the model.
*Develop an implementation plan for scaling up the model.
The project commenced in mid-2018 and is due for completion in 2024.
