Laboratory data reported through HIV surveillance can provide information about disease severity and linkage to care; however these measures are only as accurate as the quality and completeness of data reported. Using data from five states that implemented enhanced collection of laboratory data in HIV surveillance from 2005-2006, we determined completeness of reporting, stage of disease at diagnosis, the most common opportunistic illnesses (OI) at diagnosis, and linkage to medical care. Methods to enhance laboratory reporting included increasing active surveillance efforts, identifying laboratories not reporting to HIV surveillance, increasing electronic reporting, and using laboratory results from auxiliary databases. Of 3,065 persons ≥13 years of age diagnosed with HIV, 35.5% were diagnosed with stage 3 (AIDS) and 37.7% progressed to stage 3 within 12-months after diagnosis. Overall, 78.5% were linked to care within 3 months; however, a higher proportion of persons with ≥1 CD4 or viral load test was found among whites compared with blacks/African Americans (82.1% vs 73.6%, p<0.001). Few (12.3%) had an OI within 3 months of diagnosis. The completeness of laboratory data collected through surveillance was improved with enhanced reporting and provided a more accurate picture of stage of disease and gaps in linkage to care. Additional interventions are needed to meet the goals of the National HIV/AIDS Strategy on linkage to care and the reduction of HIV-related disparities.
