Brief Summary:
An observational retrospective study of NNRTI experienced patients who have virologically failed. The study aims to assess resistance profiling and subsequent prescription patterns of patients on NNRTIs

Condition or disease
HIV Positive

Detailed Description:
This is a cross-sectional study involving retrospective review of HIV-1 positive patient records who began treatment with a non-nucleoside reverse transcriptase inhibitor (NNRTI) and subsequently failed. Patients who have virologically failed previous NNRTI treatment, or have resistance to 1 drug in the NNRTI class are examined further. Such patients will have attended the clinic every 3-6 months for routine medical care. The data source for variables collected is the patient's electronic medical records. This database is located at Holdsworth House Medical Practice (HHMP), Sydney.
