Item A small cluster randomised clinical trial to improve health outcomes among Argentine patients disengaged from HIV care(2022-06) Sued, Omar; Cecchini, Diego; Rolón, María José; Calanni, Liliana; David, Daniel; Lupo, Sergio; Cahn, Pedro; Cassetti, Isabel; Weiss, Stephen M.; Alcaide, Maria Luisa; Rodriguez, Violeta J.; Mantero, Alejandro; Jones, Deborah L.Background Patients disengaged from HIV care, e.g., missed medication pick-ups, not attending physician visits, account for ≥70% of new HIV infections. Re-engaging and sustaining engagement is essential to controlling the HIV pandemic. This study tested a physician-delivered evidence-based intervention, Motivational Interviewing (MI), to improve health outcomes, adherence to antiretroviral therapy (ART), HIV virologic suppression, CD4+ count, retention in HIV care, and self-efficacy among patients disengaged from care in Argentina. Methods Regional clinics (n = 6) were randomised to condition, MI Intervention or Enhanced Standard of Care (ESOC), and recruited N = 360 patients disengaged from HIV care. ART adherence, HIV RNA viral load, CD4+ count retention, and self-efficacy were assessed at baseline, 6, 12, 18, and 24-months. Indirect effects from condition to main outcomes were examined using patient–provider relationship as a mediator. The study was a cluster-randomised clinical trial entitled Conexiones y Opciones Positivas en la Argentina 2 (COPA2) and was registered at clinicaltrials.gov, NCT02846350. Findings Participants were an average age of 39·15 (SD = 10·96), 51% were women; intervention participants were older (p = ·019), and more ESOC participants were women (60% vs. 42%, p = 0·001). Using mixed models, the intervention had no effect on ART adherence over time by condition on HIV RNA viral load, CD4+ count retention, or self-efficacy. However, analysing mediated paths, there was an indirect effect of condition on ART adherence (B = 0·188, p = 0·009), HIV viral load (B = -0·095, p = 0·027), and self-efficacy (B = 0·063, p = 0·001), suggesting the intervention was associated with improved patient–provider relationships, which was in turn associated with increased ART adherence, lower HIV viral load, and higher self-efficacy. Interpretation These findings suggest that physician-delivered MI may enhance the patient-provider relationship, self-efficacy, and ART adherence, and reduced HIV viral load in patients disengaged from HIV care. However, these findings are preliminary due to the small number of clusters randomised, and replication is warranted.Item Cumulative Burden of Mental Health Factors and Engagement in HIV Care in Argentina(2021-06) Sued, Omar; Cecchini, Diego; Abbamonte, John M; Rodriguez, Violeta J; Mandell, Lissa; Cristofari, Nicholas; Figueroa, Maria Inés; Cassetti, Isabel; Cahn, Pedro; Weiss, Stephen; Alcaide, Maria; Cahn, Florencia; Calanni, Liliana; Crinejo, Ana; David, Daniel; Lupo, Sergio; Pérez, Carolina; Pérez, Rufina; Rodriguez, Claudia; Rolón, María José; Sisto, Alicia; Trapé, Liliana; Jones, DeborahBackground: Cumulative burden of multiple mental health conditions may worsen physical health outcomes in vulnerable populations. Accordingly, identifying cumulative burdens of mental health conditions that may affect HIV treatment and care can guide public health strategies to reduce their impact on HIV-related health outcomes. This study examined the relationship between the cumulative burden of mental health conditions and factors associated with engagement in HIV care in Argentina. Method: Data for this study was obtained at baseline from Conexiones y Opciones Positivas en la Argentina 2 (COPA2). Participants (N = 360) were cisgender patients living with HIV who were lost to care, recruited from seven clinics serving people living with HIV in four Argentine urban centers. Cumulative burden of mental health conditions (i.e., depressive symptoms, problematic substance use, unhealthy alcohol use, and psychotic symptoms) was assessed. Results: Every one-point increase in the number of mental health conditions present was associated with a decrement in patient-provider communication (b = - 0.22, p < .001), self-efficacy (b = - 0.13, p = .012), and motivation for adherence (b = - 0.11, p = .039). Conclusion: This study found cumulative burden of depression, problematic substance use, unhealthy alcohol use, and psychotic symptoms to be negatively associated with factors related to engagement in HIV care. Results highlight the importance of identification and treatment of challenges to mental health, in order to ameliorate their influence on engagement in HIV care.Item Examining Adherence Among Challenging Patients in Public and Private HIV Care in Argentina(2015-3) Jones, Deborah L.; Cook, Ryan; Cecchini, Diego; Sued, Omar; Bofill, Lina; Weiss, Stephen M.; Waldrop-Valverde, D.; Lopez, María R.; Spence, Andrew.Treatment engagement, retention and adherence to care are required for optimal HIV outcomes. Yet, patients may fall below the treatment recommendations for achieving undetectable viral load or not be retained in care. This study examined the most challenging patients in Buenos Aires, Argentina, those non-adherent to HIV care. Men (n = 61) and women (n = 59) prescribed antiretrovirals (ARVs) and non-adherent to treatment in the prior 3–6 months were enrolled and assessed regarding adherence, knowledge, motivation and attitudes regarding treatment. Private clinic patients had lower viral load and higher self-reported adherence than public clinic patients. Motivations to be adherent and positive beliefs regarding ARVs were associated with increased adherence in public clinic participants. Increased self-efficacy was associated with increased adherence among participants from both clinics. Results support patient and provider interventions that strengthen the characteristics supporting adherence, engagement and retention in public and private clinic settings.Item Implementation and uptake of the Conexiones y Opciones en la Argentina (COPA) intervention: Feasibility and acceptability.(2016-4) Jones, Deborah L.; Mar, Lucas; Aristegui, Ines; Bordato, Alejandra; Fernandez Cabanillas, Graciela; Zalazar, Virginia; Sued, Omar; Cecchini, Diego; Cassetti, Isabel; Cahn, Pedro; Bofill, Lina; Weiss, Stephen M.Challenging HIV-infected patients, those neither adherent nor actively engaged in care, represent an important opportunity for intervention if the HIV epidemic is to be contained. This pilot study assessed the feasibility and acceptability of an adapted patient adherence intervention and a motivational interview-based provider intervention in urban Buenos Aires, Argentina, in order to optimize health benefits in challenging HIV-infected patients. To maximize implementation and uptake of both strategies, interventions were adapted to the local setting. Qualitative data and a short quantitative assessment from patients, staff, fellows, residents and physicians (n = 84) were examined to establish the feasibility and acceptability of offering patient and provider evidence-based interventions in both public and private health-care settings. Results identified key themes on provision of information, use of specialized communication techniques and group support in the utilization of the interventions. Both providers (n = 12) and patients (n = 120) endorsed the acceptability and value of the interventions, and the feasibility of their delivery. Findings support the use of both intervention modalities with challenging patients in diverse urban health-care settings.Item Improving Adherence to Care Among “Hard to Reach” HIV-Infected Patients in Argentina(2015-7) Jones, Deborah L; Sued, Omar; Cecchini, Diego; Bofill, Lina; Cook, R; Lucas, Mar; Bordatto, Alejandra; Cassetti, Isabel; Cahn, Pedro; Weiss, Stephen MMany HIV-infected patients fail to achieve undetectable viral load and are not retained in care. This pilot study examined patients lost to care in public and private clinics in Buenos Aires, Argentina. The impact of patient and provider interventions was compared separately and collectively. In Phase 1, participants prescribed antiretrovirals (ARVs) and non-adherent to treatment in the prior 3 to 6 months (n = 60) were randomized to patient intervention or standard of care (SOC) and assessed over 12 months. In Phase 2, providers were trained in interviewing techniques and 60 additional patients were randomized to patient intervention or SOC condition. Averaged across patient intervention status, Phase 2 provider intervention patients reported the most improved adherence and viral suppression at 6 and 12 months. Adherence in “patient intervention only” improved at midpoint and returned to baseline at 12 months. Results suggest provider training sustained patient adherence and viral suppression among “hard to reach” patients.Item Motivational Interviewing Training for HIV Care Physicians in Argentina: Uptake and Sustainability of an Effective Behavior Change Intervention(2021-06) Rodriguez, Violeta J; Abbamonte, John M; Alcaide, Maria Luisa; Rodriguez Yanes, Nicolle L; de la Rosa, Aileen; Sued, Omar; Cecchini, Diego; Weiss, Stephen M; Jones, Deborah LMotivational interviewing (MI) utilizes a patient-centered approach to address patient ambivalence about treatment and has been found to improve treatment ART adherence among patients living with HIV disengaged from care. This study examined MI training for clinicians, uptake, and sustainability over time. Clinics (n = 7) with N = 38 physicians were randomized to condition (MI, Enhanced Standard of Care). Physicians completed video- recorded patient consultations at baseline and 6, 12, and 18-month follow-up. MI condition physicians had greater relational and technical scores over time and were more likely to adhere to and sustain MI over time. Overall, physicians found the MI training highly acceptable and were able to sustain their skills. Results illustrate the feasibility of MI training, implementation, and sustainment over 18 months. Findings support previous research in Argentina in which trained physicians found MI useful with challenging patients. Broader implementation of MI among HIV care physicians in Argentina is merited.Item Physician-delivered motivational interviewing to improve adherence and retention in care among challenging HIV-infected patients in Argentina (COPA2): study protocol for a cluster randomized controlled trial(2018-07-24) Sued, Omar; Cassetti, Isabel; Cecchini, Diego; Cahn, Pedro; de Murillo, Lina Bofill; Weiss, Stephen M; Mandell, Lissa N; Soni, Manasi; Jones, Deborah LBackground “Challenging” HIV-infected patients, those not retained in treatment, represent a critical focus for positive prevention, as linkage to care, early initiation of antiretroviral therapy, adherence and retention in treatment facilitate viral suppression, thus optimizing health and reducing HIV transmission. Argentina was one of the first Latin American countries to guarantee HIV prevention, diagnosis and comprehensive care services, including antiretroviral medication, which removed cost and access as barriers. Yet, dropout occurs at every stage of the HIV continuum. An estimated 110,000 individuals are HIV-infected in Argentina; of these, 70% have been diagnosed and 54% were linked to care. However, only 36% have achieved viral suppression and 31% of those diagnosed delayed entry to care. To achieve meaningful reductions in HIV infection at the community level, innovative strategies must be developed to re-engage patients. Motivational Interviewing (MI) is a patient-centered approach and has been used by therapists in Central and South America to enhance motivation and commitment in substance use and risk reduction. Our pilot feasibility study utilized culturally tailored MI in physicians to target patients not retained in treatment in public and private clinics in Buenos Aires, Argentina. Results demonstrated that a physician-based MI intervention was feasible and effective in enhanced and sustained patient adherence, viral suppression, and patient-physician communication and attitudes about treatment among these patients at 6 and 9 months post baseline. Methods/design This clinical trial seeks to extend these findings in public and private clinics in four urban population centers in Argentina, in which clinics (n = 6 clinics, six MDs per clinic site) are randomized to experimental (physician MI Intervention) (n = 3) or control (physician Standard of Care) (n = 3) conditions in a 3:3 ratio. Using a cluster randomized clinical trial design, the study will test the effectiveness of a physician-based MI intervention to improve and sustain retention, adherence, persistence, and viral suppression among “challenging” patients (n = 420) over 24 months. Discussion Results are anticipated to have significant public health implications for the implementation of MI to re-engage and retain patients in HIV treatment and care and improve viral suppression through high levels of medication adherence.

Though people living with HIV are at increased risk for suicidal behavior, little research on suicide risk has been conducted among HIV-positive people in this region. This study examined risk factors for suicidal ideation among HIV-infected adults (N = 360) re-engaging in care in Argentina. Overall, 21% of participants reported suicidal ideation in the past week. In adjusted logistic regression models, younger age, increased depressive symptomatology, and drug abuse were associated with suicidal ideation (p < 0.05); decreased motivation for adherence and fewer months since initiating antiretroviral therapy approached significance (p = 0.07). Suicidal ideation was common in this sample of HIV-positive patients in Argentina. Findings highlight the need for routine risk assessment and interventions integrated into the HIV care continuum, addressing depression, substance use, and suicidal behavior.Item Suicidality among nonadherent patients living with HIV in Buenos Aires, Argentina: prevalence and correlates(2018-04-01) Rodriguez, Violeta J; Sued, Omar; Cecchini, Diego; Mandell, Lissa N; Bofill, Lina; Weiss, Stephen M; Cassetti, Isabel; Cahn, Pedro; Jones, Deborah LOf those in the general population hospitalized for suicidal ideation and suicide attempts in Argentina, many reattempt suicide and are readmitted. However, few studies in Argentina have examined suicidal ideation and suicide-related behaviors among people living with HIV (PLHIV) and none have examined these factors among nonadherent PLHIV, though the prevalence of suicidal ideation in this group may be higher than in the general population and also than in other groups of PLHIV. This study of PLHIV in Buenos Aires, Argentina, examined the correlates of suicidal ideation in nonadherent PLHIV. Nonadherent patients with HIV (N = 118) were recruited from two clinics providing outpatient healthcare services to PLHIV in Buenos Aires, Argentina. Participants completed assessments on demographic characteristics, depression and suicidality, stigma, and self-efficacy. Participants were HIV-infected men (51%) and women (49%) with a median age of 40 years (IQR = 11). About half had completed high school or more, two-thirds were employed, and had a mean monthly income of 4196.79 (SD = 3179.64) Argentine pesos (USD$221). Thirty-three (28% [95% CI 20.3, 37.3]) participants reported suicidal ideation in the past two weeks, and one-third (35.6% [27.1, 44.9]) reported lifetime suicidal ideation. In bivariate analyses, attending a public clinic, being female, younger, unemployed, and experiencing greater stigma and depression were associated with suicidal ideation. In multivariable logistic regression, stigma interacted with the number of years since HIV diagnosis to predict suicidal ideation. The impact of stigma on suicidal ideation decreased with time since HIV diagnosis, suggesting that suicidal ideation may arise following HIV diagnosis due to perception of HIV-related stigma. Interventions to reduce perceived stigma during the period following HIV diagnosis may reduce suicidal ideation in this population. Organizational initiatives that explore HIV stigma microagressions in the healthcare setting may be needed to optimize health outcomes.Item Women of Reproductive Age Living with HIV in Argentina: Unique Challenges for Reengagement in Care(2019-10-18) Cecchini, Diego; Alcaide, Maria Luisa; de Jesus Rodriguez, Violeta; Mandell, Lissa Nicole; Abbamonte, John Michael; Cassetti, Isabel; Cahn, Pedro; Sued, Omar; Weiss, Stephen; Deborah, JonesThis study evaluated the reasons for not taking antiretroviral treatment (ART) among women of reproductive age who are disengaged from HIV care (have missed pharmacy pickups and physician visits), with the goal of identifying strategies for reengagement in HIV care. Participants were cisgender women (n = 162), 18 to 49 years of age, and who completed sociodemographic, medical history, reasons why they were not taking ART, mental health, motivation, and self-efficacy assessments. Latent class analysis was used for analysis. Women who reported avoidance-based coping (avoid thinking about HIV) had higher depression (U = 608.5, z = −2.7, P = .007), lower motivation (U = 601, z = −2.8, P = .006), and lower self-efficacy (U = 644.5, z = −2.4, P = .017) than those not using this maladaptive strategy. As women living with HIV experience a disproportionate burden of poor health outcomes, interventions focused on the management of depression may improve HIV outcomes and prevent HIV transmission.
