This is an observational study called OPERA, which aims to improve how we use electronic health records (EHR) to understand and manage chronic diseases like HIV/AIDS, liver diseases, inflammatory bowel diseases, and cardiovascular diseases. Instead of testing a new treatment, researchers will look at existing patient data from doctors' offices to learn more about how these conditions are treated in the real world. The study will track how well patients respond to their current therapies, specifically looking at their virologic response (how well a treatment controls a virus) after one year. This study is open to patients of all ages and genders who are treated in participating practices and whose treatment information is in their electronic health records. The study is currently unclear on its recruitment status and plans to include a very large number of participants.
