Validation of LexisNexis Accurint in the Georgia Cancer Registry's Cancer Recurrence and Information Surveillance Program.

BACKGROUND: LexisNexis Accurint is a database of ~84 billion public records that includes an individual's location of residence. Its ability to track residences longitudinally has not been validated. This study used the Georgia Cancer Registry's (GCR's) Cancer Recurrence and Information Surveillance Program (CRISP) to validate the U.S. state of residence and to examine characteristics of patients not included or who had an inaccurate entry in LexisNexis. METHODS: The GCR is routinely linked to the National Death Index (NDI), providing information regarding the state of residence in which the patient died. We compared the state of residence reported in LexisNexis with the NDI gold standard state of residence at death. Multivariate logistic regression analyses estimated associations between demographic information and: (1) having a mismatch between LexisNexis and NDI and (2) being missed in LexisNexis. RESULTS: Of the 69,494 patients in the CRISP cohort, 65,890 (95%) were found in LexisNexis and 9,597 (14%) had died. Among a subset of patients who were deceased, the sensitivity of LexisNexis for identifying persons who left Georgia was 42% and the specificity was 89%. Minority groups were more likely to be missed in the LexisNexis database as well as to have discordance between LexisNexis and NDI state of residence at death. CONCLUSIONS: LexisNexis Accurint failed to identify the emigration of more than half of deceased CRISP patients who had left Georgia but correctly identified most who had remained. The validity of the state of residence is important for studies using LexisNexis as a tool for follow-up.

"Cure" Versus "Clinical Remission": The Impact of a Medication Description on the Willingness of People Living with HIV to Take a Medication.

Many people living with HIV (PLWHIV) state that they would be willing to take significant risks to be "cured" of the virus. However, how they interpret the word "cure" in this context is not clear. We used a randomized survey to examine whether PLWHIV had a different willingness to take a hypothetical HIV medication if it causes flu-like symptoms, but provides: (a) cure, (b) remission that was labeled "cure", or (c) remission. PLWHIV (n = 454) were more willing to take a medication that provided a "cure" versus a "remission" if the side effects lasted less than 1 year. PLWHIV were more willing to take a medication that provided a remission that was labeled "cure" versus a "remission" (p = 0.01) if the side effects lasted 2 weeks. Clinicians and researchers should be aware of the impact of the word "cure" and ensure that PLWHIV fully understand the possible outcomes of their treatment options.
