Dynamics of Treatment Supporters and Patients Starting HIV Therapy in Lima, Peru

Relationship Between Social Support and Clinical Outcomes: An Evaluation of Participant-Nominated Treatment Supporters in the HOPE 4 Intervention

BACKGROUND

The HOPE 4 trial (Heart Outcomes Prevention and Evaluation 4) investigated the effectiveness of a comprehensive, collaborative model of care, implemented in Colombia and Malaysia, which aimed to reduce cardiovascular disease risk in individuals with hypertension. One component of this intervention was the nomination of a treatment supporter, where participants could select a family member or friend to assist them with their care. The purpose of this study was to investigate the impact of these individuals on participant outcomes, as well as the relationship dynamics between participants and their treatment supporter.

METHODS

Participants in the HOPE 4 intervention group with baseline and 12 months of follow-up were included for analysis. They were divided into Every Visit (n=339) and

RESULTS

Groups were majority female (53% versus 62%) with a mean age of 63 and 66 years. Country of origin differed between groups (22% versus 86%; Colombia). A 15.5% ([95% CI, 6.2%-24.8%] P=0.004) greater increase in statin medication use was reported in the Every Visit group at 12 months compared with the

CONCLUSIONS

Long-term support from a nominated treatment supporter was associated with improved adherence, risk factor management, and medication use among individuals with hypertension.

HIV understanding, experiences and perceptions of HIV-positive men who have sex with men in Amazonian Peru: a qualitative study

BACKGROUND

HIV-related incidence and mortality is increasing across Peru, with highest mortality rates recorded in the Amazonian region of Loreto. This epidemic is concentrated in men who have sex with men, a population with 14% HIV treatment adherence despite free national provision. This study investigates barriers and facilitators to following healthcare advice through experiences and perceptions of HIV-positive men who have sex with men and healthcare professionals in Loreto.

METHODS

Twenty qualitative interviews with HIV-positive men who have sex with men and one focus group with HIV-specialist healthcare professionals were conducted in Loreto, January-February 2019. Interviews were transcribed per verbatim. Thematic content analysis and deviant case analysis were used.

RESULTS

A culture of isolation and discrimination was identified, propagated by poor public knowledge surrounding HIV transmission and treatment. Employment potential was hampered and 7/20 patients had suicidal thoughts post-diagnosis. Barriers to care included: shame, depression, travel cost/times, a preference for traditional plant-based medicine and side-effects of antiretroviral therapy. Facilitators included: education, family and clinic support, disease acceptance and lifestyle changes.

CONCLUSION

More effective, focussed community education and workplace discrimination investigations are recommended to reduce stigma and increase adherence to treatment in this population.
