The Denver HIV Risk Score is a clinical calculator used to assess the risk of HIV infection in patients. It is specifically designed for individuals who are undergoing HIV testing, particularly those who are considered to be at high risk due to their lifestyle, sexual behavior, or other risk factors. The score is calculated based on a variety of factors including age, gender, race/ethnicity, sexual behavior, drug use, and symptoms of sexually transmitted infections. The clinical utility of this calculator is to help clinicians identify individuals who are at a higher risk of HIV infection and may benefit from more frequent testing or other preventive measures. It is not intended to be used as a diagnostic tool for HIV, but rather as a risk stratification tool. There are no specific exclusion criteria for its use, but it may be less accurate in populations with a low prevalence of HIV.
