COVID-19 studies are our top priority. For all other studies, we recommend commencing the registration process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission as we are experiencing 4 week turn-around time in review of submissions and resubmissions. We currently do not have the capacity to expedite reviews.

Note also there are additional delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Brief summary
The purpose of this study is to determine linkage and retention in care in patients with HIV

Care Practice in Sydney, Australia.

The investigators hypothesise that patients attending HHMP will have higher rates of linkage
and retention in care than the US HIV-infected population, and equivalent to Australian
