Background Patient-delivered partner therapy (PDPT) for chlamydia is an effective and safe additional partner management strategy. Some Australian regulatory changes have been made to support PDPT, but implementation guidance is lacking. This paper describes a pilot implementation program of PDPT in New South Wales (NSW), the Australian Development and Operationalisation of Partner Therapy (ADOPT). Methods: ADOPT involved: (1) clarification of the NSW PDPT legal and policy framework; (2) development and implementation of PDPT service models, resources and data collection tools for select publicly funded sexual health services (PFSHS) and Family Planning (FP) NSW clinics; and (3) evaluation of PDPT uptake. Results: PDPT can be undertaken in NSW if accompanied by adequate provider, patient and partner information. Regulatory amendments enabled medication prescribing. The pilot implementation took place in four PFSHS and five FPNSW clinics from January to December 2016. In PFSHS, 30% of eligible patients were offered PDPT and 89% accepted the offer. In FPNSW clinics, 42% of eligible patients were offered PDPT and 63% accepted the offer. Most partners for whom PDPT was accepted were regular partners. Conclusions: A close collaboration of researchers, policy makers and clinicians allowed successful implementation of a PDPT model for chlamydia in heterosexual patients at select PFSHS and FPNSW clinics, providing guidance on its use as standard of care. However, for the full public health benefits of PDPT to be realised, it must be implemented in general practice, where most chlamydia is diagnosed. Further work is recommended to explore feasibility, develop guidelines and promote the integration of PDPT into general practice.
