Partner counseling and referral services for HIV infection: new endorsement of an old approach

Changes in sexual behaviors among HIV-infected individuals after their HIV diagnosis in a rural prefecture of Eastern China

OBJECTIVE

To describe changes in sexual behaviors among HIV-infected individuals after their HIV diagnosis.

METHODS

All HIV-infected individuals diagnosed by the end of 2009 in Taizhou Prefecture were invited to participate in this 12-month prospective study. Assessments including the total number and types of sexual contacts, and condom use details for up to their most familiar eight sexual contacts were collected both at enrollment and 12-month follow-up.

RESULTS

262 HIV-infected individuals were eligible for analysis. The total number of sexual contacts reported by participants was 4,017, 1,496 and 356 during the 12- month period prior to HIV diagnosis (T1), the 12-month period prior to the baseline survey (T2), and the 12-month follow-up period (T3), respectively. The difference in the number of sexual contacts between T2 and T1 was -5 in median (IQR -1, -14), and the difference between T3 and T2 was 0 in median (IQR: 0, -6). A larger proportion of spousal or long-term heterosexual contact was reported from T1(27.7%) to T2(42.5%) to T3(76.1%), whereas a smaller proportion of commercial heterosexual contacts was reported from T1 (48.6%) to T2 (33.2%) to T3 (7.0%) as well as a smaller proportion of non-commercial casual homosexual contacts was reported from T2 (8.4%) to T3 (3.8%).The proportion of consistent condom use increased significantly from T1 (9.3%) to T2 (35.3%) to T3 (91.5%).

CONCLUSION

Sexual behaviors did not change in a uniform manner for the participants in our study. Sexual behaviors and sexual networks vis-à-vis HIV diagnosis and follow-up were associated with the participant's characteristics and HIV infection and treatment status. The overall lesson is that individuals who are unaware of their HIV infection are the main drivers of secondary transmission. Early identification of HIV infection and access to antiretroviral therapy (ART) are both key strategies to the control and prevention.

Partner Referral by HIV-Infected Persons to Partner Counseling and Referral Services (PCRS) - Results from a Demonstration Project

Objective:

The objectives of this article are to determine factors associated with refusal and agreement to provide partner information, and evaluate the effectiveness of referral approaches in offering PCRS.

Methods:

Index clients from 5 sites that used 3 different PCRS approaches were interviewed to obtain demographic and risk characteristics and choice of partner referral method for PCRS. Logistic regression was used to assess factors associated with providing partner information.

Results:

The percentage of index clients who refused to provide partner information varied by site (7% to 88%). Controlling for PCRS approach, index clients who were older than 25 years, male, or reported having male-male sex in the past 12 months were more likely (p <0.01) to refuse to provide partner information. Overall, 72% of named partners referred by index clients were located and offered PCRS. The proportion of partners who were located and offered PCRS differed by referral approach used, ranging from 38% using contract referral (index clients agree to notify their partners within a certain timeframe, else a disease intervention specialist or health care provider will notify them) to 98% using dual referral (index clients notify their partners with a disease intervention specialist or provider present).

Conclusion:

Success in obtaining partner information varied by the PCRS approach used and effectiveness in locating and notifying partners varied by the referral approach selected. These results provide valuable insights for enhancing partner services.

Costs and effectiveness of partner counseling and referral services with rapid testing for HIV in Colorado and Louisiana, United States

OBJECTIVE

Health departments offer partner counseling and referral services (PCRS) to HIV-infected index patients and their partners. Point-of-care rapid HIV testing makes it possible for partners of index patients to learn their HIV serostatus in nonclinical settings.

STUDY DESIGN

We assessed costs and effectiveness of PCRS with rapid HIV testing in Colorado and Louisiana (April 2004-January 2006). Colorado provided PCRS to the index patients and partners statewide; Louisiana provided PCRS to those in Baton Rouge and New Orleans. The key effectiveness measures were number of partners tested and number of partners informed of a new HIV diagnosis after rapid testing. We obtained program costs for personnel, travel, utilities, supplies, equipment, and facility space.

RESULTS

Colorado identified a yearly average of 328 index patients and 253 partners and tested 43 partners. Louisiana identified a yearly average of 81 index patients and 138 partners and tested 83 partners. The rates of previously undiagnosed HIV infection among partners tested were 6.6% in Colorado and 9.9% in Louisiana. The average costs per partner tested and per partner informed of a new HIV diagnosis were $1459 and $22,243 in Colorado and $714 and $7231 in Louisiana.

CONCLUSIONS

Program costs varied substantially by location. Our analysis helps program managers and health care providers to understand the resources needed for implementing the PCRS in diverse settings.

HIV partner notification: predictors of discussion and agreements from provider reports

This study examines organizational, provider, client, and test-event level predictors of HIV partner notification (PN) discussion and agreements based on providers' most recent HIV-positive post-test counseling session. Staff (n = 621) were sampled from for-profit, nonprofit, and county government HIV testing organizations (N = 159) in Los Angeles County from 2003 to 2007. Among providers who conducted an HIV-positive post-test counseling session (n = 204), 65% discussed PN but only 10% had confirmed agreement to provider-involved PN (PIPN). In multi-level regression analyses PN discussion was predicted by provider HIV-test training and knowledge, and patients requesting a test while presenting HIV/AIDS symptoms. The strongest predictor of PIPN agreement was public health HIV testing settings followed by counseling by program managers or infectious disease specialists across settings. None of the injecting drug users or patients presenting with AIDS, but not requesting a test, agreed to PIPN. Organizational and provider-level interventions on PN will be needed to realize cost-effective benefits of expanded HIV testing and counseling.
