RETURNING FOR CONFIRMATORY TEST RESULTS: THE CRITICAL LINK
BETWEEN “TEST” AND “TREAT” IN RAPID HIV TESTING
Matthew B. Feldman, Ph.D., MSWGay Men’s Health Crisis

THE “TEST” AND “TREAT” INITIATIVE
• Increase the number of people who become aware that they are HIV-positive through expanded testing efforts
• Link recently HIV-infected individuals to medical care
• Initiate HAART at earlier stages of disease
(Dieffenbach & Fauci, 2009; Dodd, Garnett, & Hallett, 2010)
IDENTIFYING HIV-POSITIVE INDIVIDUALS USING RAPID HIV
TESTING• Reactive rapid test results must be confirmed by a
Western Blot
• Confirmatory HIV test results are usually available within 1-2 weeks
• Most HIV social service and medical organizations require documentation of a positive confirmatory HIV test result before services can be initiated
FAILURE TO RETURN RATES FOR HIV TEST RESULTS
• Failure to return rates for confirmatory HIV test results range from 19-25%
(Antonio-Gaddy et al., 2006; Bowles et al., 2008; Bucher et al., 2007)
• Failure to return rates for conventional HIV test results range from 11%-58%
(Desai & Rosenheck, 2004; Erbelding et al., 2004; Hightow et al., 1999; Lazebnik et al., 2001 Molitor et al., 1999; Stein & Nyamathi, 2000; Slutsker et al., 1992; Tao et al., 1999; Valdisseri et al., 1993; Wiley et al., 1998; Zick et al., 2000)

STUDY AIMS
• To describe the prevalence of returning for confirmatory HIV test results among individuals newly diagnosed HIV-positive at GMHC’s HIV testing and counseling center
• To examine the sociodemographic and psychosocial correlates of returning for confirmatory HIV test results
UNDERSTANDING RETURNING FOR CONFIRMATORY HIV TEST RESULTS: THE BEHAVIORAL MODEL OF HEALTH
SERVICES USE (ANDERSEN ET AL., 2000)
GMHC HIV TESTING PROCEDURES
• Confidential, code-based rapid HIV testing is conducted on-site, off-site, and in a mobile testing unit by trained HIV testing counselors/phlebotomists
• Pre- and post-test counseling is provided to all individuals who receives an HIV test
• Individuals with a preliminary positive result are asked to return in 1-2 weeks for confirmatory HIV test results

• A substantial proportion of individuals (45%) in this sample would not have progressed through the early phase of test and treat
• Health insurance, HIV test site, sexual orientation, and housing situation emerged as significant predictors of returning for confirmatory HIV test results
CONCLUSION
• First study to examine the correlates of returning for confirmatory test results
• Limitations
DISCUSSION
• Need to better understand the reasons people fail to return for confirmatory test results, particularly in the context of off-site HIV testing
• Challenge: how can post-test counseling address psychosocial obstacles to returning for confirmatory test results?
