3 missed opportunities! If current guidelines used, HIV could have been diagnosed up to 8 years earlier

Learning Points

• This patient came from a country of low HIV prevalence and was probably not believed to be at risk of HIV infection • Because of this the otherwise excellent medical teams looking after her presumably did not think of HIV even though the diagnosis seems obvious with hindsight • However, the suspected PUO and Hepatitis B and TB diagnoses were a red flag for possible HIV infection • A perceived lack of risk should not deter you from offering a test when clinically indicated

Key messages

• Antiretroviral therapy (ART) has transformed treatment of HIV infection • The benefits of early diagnosis of HIV are well recognised - not offering HIV testing represents a missed opportunity • UK guidelines recommend screening for HIV in adult populations where undiagnosed prevalence is >1/1000 as it has been shown to be cost-effective • HIV screening should be a routine test on presentation of PUO or weight loss of otherwise unknown cause • HIV screening should be routine in services for patients diagnosed with Hepatitis B and TB
