Management of Chlamydia Cases in Australia (MoCCA)

Project Details


Management of Chlamydia Cases in Australia (MoCCA) is a National Health and Medical Research Council-funded Partnership Grant that will develop a model for strengthening chlamydia case management in general practice. We are currently in the early stages of the MoCCA project and are seeking to better understand the context for chlamydia management in general practice.  We want to hear from health consumers, general practitioners, practice nurses and practice managers about how chlamydia infections are managed in general practice and your thoughts on whether there are opportunities for improvement.

Interested in participating?

We welcome your involvement in the following participation opportunities:

*If you are a general practitioner working in Australia, you can complete an online survey about chlamydia case management here:

*If you have tested positive for chlamydia infection in the past 12 months, and are interested in participating in a telephone interview about your experience of diagnosis and management, email us:

*General practice clinics interested in helping us spread the word that we wish to speak to people recently diagnosed with chlamydia by displaying our recruitment poster can download the poster here:

Your input will help us to develop a model of care that will help to strengthen how chlamydia infections are managed in general practice.

What we will be working on next:

The next phases of MoCCA will involve testing the chlamydia case management model in some general practice clinics. We will be recruiting general practice clinics to participate in this aspect of the project soon. If you are a GP, practice nurse or practice manager and think your practice might be interested in participating, please contact us at

About 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); this highlights the importance of strategies to prevent reinfection. Chlamydia can also lead to ectopic pregnancy and tubal factor infertility.

In Australia, general practice is a critical sector for chlamydia control because over 80% of chlamydia cases are diagnosed in this setting. The Australian Chlamydia Control Effectiveness Pilot was the first trial to show that increasing chlamydia screening in general practice will not reduce the burden of chlamydia in the population and identified considerable gaps in chlamydia case management to prevent reinfection. In response to these findings, there is now considerable ongoing discussion internationally that chlamydia control policy must prioritise case management through effective partner notification 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 notification, chlamydia retesting and PID management in sexual health/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, in Australian general practice, to:

  • 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 2023.
