RESUMO

BACKGROUND: Black adults who smoke and have HIV experience immense stressors (eg, racial discrimination and HIV stigma) that impede smoking cessation success and perpetuate smoking-related health disparities. These stressors also place Black adults who smoke and have HIV at an increased risk of elevated interoceptive stress (eg, anxiety and uncomfortable bodily sensations) and smoking to manage symptoms. In turn, this population is more likely to smoke to manage interoceptive stress, which contributes to worse HIV-related outcomes in this group. However, no specialized treatment exists to address smoking cessation, interoceptive stress, and HIV management for Black smokers with HIV. OBJECTIVE: This study aims to test a culturally adapted and novel mobile intervention that targets combustible cigarette smoking, HIV treatment engagement and adherence, and anxiety sensitivity (a proxy for difficulty and responsivity to interoceptive stress) among Black smokers with HIV (ie, Mobile Anxiety Sensitivity Program for Smoking and HIV [MASP+]). Various culturally tailored components of the app are being evaluated for their ability to help users quit smoking, manage physiological stress, and improve health care management. METHODS: This study is a pilot randomized controlled trial in which Black combustible cigarette smokers with HIV (N=72) are being recruited and randomly assigned to use either (1) the National Cancer Institute's QuitGuide app or (2) MASP+. Study procedures include a web-based prescreener; active intervention period for 6 weeks; smartphone-based assessments, including daily app-based ecological momentary assessments for 6 weeks (4 ecological momentary assessments each day); a video-based qualitative interview using Zoom Video Communications software at week 6 for participants in all study conditions; and smartphone-based follow-up assessments at 0, 1, 2 (quit date), 3, 4, 5, 6, and 28 weeks postbaseline (26 weeks postquitting date). RESULTS: Primary outcomes include biochemically verified 7-day point prevalence of abstinence, HIV-related quality of life, use of antiretroviral therapy, and HIV care appointment adherence at 26 weeks postquitting date. Qualitative data are also being collected and assessed to obtain feedback that will guide further tailoring of app content and evaluation of efficacy. CONCLUSIONS: The results of this study will determine whether the MASP+ app serves as a successful aid for combustible cigarette smoking cessation, HIV treatment engagement, and physiological stress outcomes among Black people with HIV infection. If successful, this study will provide evidence for the efficacy of a new means of addressing major mental and physical health difficulties for this high-risk population. If the results are promising, the data from this study will be used to update and tailor the MASP+ app for testing in a fully powered randomized controlled trial that will evaluate its efficacy in real-world behavioral health and social service settings.

RESUMO

OBJECTIVE: The HIV epidemic remains a significant public health issue in the United States. HIV risk prediction models could be beneficial for reducing HIV transmission by helping clinicians identify patients at high risk for infection and refer them for testing. This would facilitate initiation on treatment for those unaware of their status and pre-exposure prophylaxis for those uninfected but at high risk. Existing HIV risk prediction algorithms rely on manual construction of features and are limited in their application across diverse electronic health record systems. Furthermore, the accuracy of these models in predicting HIV in females has thus far been limited. MATERIALS AND METHODS: We devised a pipeline for automatic construction of prediction models based on automatic feature engineering to predict HIV risk and tested our pipeline on a local electronic health records system and a national claims data. We also compared the performance of general models to female-specific models. RESULTS: Our models obtain similarly good performance on both health record datasets despite difference in represented populations and data availability (AUC = 0.87). Furthermore, our general models obtain good performance on females but are also improved by constructing female-specific models (AUC between 0.81 and 0.86 across datasets). DISCUSSION AND CONCLUSIONS: We demonstrated that flexible construction of prediction models performs well on HIV risk prediction across diverse health records systems and perform as well in predicting HIV risk in females, making deployment of such models into existing health care systems tangible.

RESUMO

Chagas disease (CD), caused by Trypanosoma cruzi, is underdiagnosed in the United States. Improved screening strategies are needed, particularly for people at risk for life-threatening sequelae of CD, including people with human immunodeficiency virus (HIV, PWH). Here we report results of a CD screening strategy applied at a large HIV clinic serving an at-risk population.

RESUMO

PURPOSE: Alcohol use disorder (AUD) is highly prevalent among Veterans with HIV. Rural Veterans with HIV are at especially high risk for not receiving appropriate treatment. This retrospective cohort cross-sectional study aimed to investigate patterns of mental health treatment utilization across delivery modality among Veterans diagnosed with HIV and AUD. It was hypothesized that rural Veterans with HIV and AUD would receive a lower rate of mental health treatment delivered via video telehealth than urban Veterans with HIV and AUD. METHODS: A national Veterans Health Association administrative database was used to identify a cohort of Veterans diagnosed with HIV and AUD (N = 2,075). Geocoding was used to categorize rural Veterans (n = 246) and urban Veterans (n = 1,829). Negative binomial regression models tested associations between rurality and mental health treatment delivered via face-to-face, audio-only, and video telehealth modalities. FINDINGS: Results demonstrated that rural Veterans with HIV and AUD received fewer mental health treatment sessions delivered via telehealth than urban Veterans with HIV and AUD (incidence rate ratio = 0.62; 95% confidence intervals [0.44, 0.87]; P < .01). No differences were found in terms of treatment delivered face-to-face or by audio-only. CONCLUSIONS: Rural Veterans with HIV and AUD represent a vulnerable subpopulation of Veterans who may most benefit from video telehealth. Efforts to increase access and improve the uptake of evidence-based mental health treatment delivered via video telehealth are needed.

RESUMO

PURPOSE OF REVIEW: Despite the availability of safe and effective oral combination antiretroviral therapy, barriers to maintaining viral suppression remain a challenge to ending the HIV epidemic. Long-acting injectable antiretroviral therapy was developed as an alternative to daily oral therapy. This review summarizes the current literature on the efficacy of long-acting cabotegravir plus rilpivirine for the treatment of HIV-1, reasons to switch to injectable therapy, and barriers to switching. RECENT FINDINGS: Long-acting cabotegravir plus rilpivirine is safe and effective in maintaining HIV-1 virologic suppression. Ideal candidates for switching to long-acting cabotegravir plus rilpivirine are virologically suppressed on oral regimens with good adherence and no history of virologic failure or baseline resistance. Indications to switch to injectable therapy include patient preference, the potential for improved adherence, and avoidance of adverse effects. Implementation research is needed to assess and overcome system barriers. Long-acting cabotegravir plus rilpivirine is a novel alternative to oral antiretrovirals, with the potential to improve adherence and quality of life in people with HIV.

RESUMO

OBJECTIVES: Inpatient rounding is a foundational component of medical education in academic hospitals. The coronavirus 2019 (COVID-19) pandemic disrupted traditional inpatient rounding practices. The objectives of this study were to describe how Internal Medicine inpatient team rounding changed because of COVID-19-related precautions and the effect of these changes on education during rounds. METHODS: During February to March 2021, we conducted four virtual focus groups with medical and physician assistant students, interns, upper-level residents, and attending physicians at the Michael E. DeBakey Veterans Affairs Medical Center in Houston, Texas, and designed a codebook to categorize focus group commentary. RESULTS: Focus groups revealed that students believed that certain physical-distancing measures in place early on during the pandemic were ineffective and significantly limited their ability to evaluate patients in person. Residents described increased stress levels related to potential severe acute respiratory-coronavirus 2 exposure and limited time at the bedside, which affected their confidence with clinical assessments. Rounding-team fragmentation precluded the entire team learning from all of the patients on the team's census. Loss of intrateam camaraderie impaired the development of comfortable learning environments. CONCLUSIONS: This study evaluated Internal Medicine team member focus groups to describe how the COVID-19 pandemic affected medical education during rounds. Academic teaching programs can adapt the findings from this study to address and prevent pandemic-related gaps in medical education during rounds now and during future potential disruptions to medical education.

RESUMO

BACKGROUND: Despite the growing concern that people with HIV (PWH) will experience a disproportionate burden of dementia as they age, very few studies have examined the sex-specific prevalence of dementia, including Alzheimer disease and related dementias (AD/ADRD) among older PWH versus people without HIV (PWOH) using large national samples. METHODS: We constructed successive cross-sectional cohorts including all PWH aged 65+ years from U.S. Medicare enrollees and PWOH in a 5% national sample of Medicare data from 2007 to 2019. All AD/ADRD cases were identified by ICD-9-CM/ICD-10-CM diagnosis codes. Prevalence of AD/ADRD was calculated for each calendar year by sex-age strata. Generalized estimating equations were used to assess factors associated with dementia and calculate the adjusted prevalence. RESULTS: PWH had a higher prevalence of AD/ADRD, which increased over time compared with PWOH, especially among female beneficiaries and with increasing age. For example, among those aged 80+ years, the prevalence increased from 2007 to 2019 (females with HIV: 31.4%-44.1%; females without HIV: 27.4%-29.9%; males with HIV: 26.2%-33.3%; males without HIV: 21.0%-23.5%). After adjustment for demographics and comorbidities, the differences in dementia burden by HIV status remained, especially among older age groups. CONCLUSIONS: Older Medicare enrollees with HIV had an increased dementia burden over time compared with those without HIV, especially women and older subjects. This underscores the need to develop tailored clinical practice guidelines that facilitate the integration of dementia and comorbidity screening, evaluation, and management into the routine primary care of aging PWH.

RESUMO

OBJECTIVE: The COVID-19 pandemic necessitated use of remote assessments by clinical neuropsychologists. Telehealth was particularly important for vulnerable groups, including persons living with HIV (PLWH); however, limited internet access can be a serious barrier to care. This study examined the preliminary validity of a telephone-based neuropsychological assessment in a clinical sample of PLWH. METHOD: A consecutive series of 59 PLWH were assessed via telephone at an HIV clinic in the southern U.S. between April 2020 and July 2022. The battery included auditory-verbal neuropsychological tests of memory, attention, and executive functions, and questionnaires assessing self-reported mood and activities of daily living (ADL). RESULTS: Study measures demonstrated acceptable internal consistency. PLWH demonstrated worse neuropsychological performance compared with expectations derived from the normal curve and an HIV-seronegative adult sample (N = 44). PLWH assessed via telephone demonstrated similar impairment rates to that of a consecutive series of PLWH (N = 41) assessed in-person immediately prior to the pandemic. Higher telephone-based global neuropsychological scores were related to younger age, more education, better fund of knowledge, White race/ethnicity, fewer medical conditions, and fewer depression symptoms. Global neuropsychological impairment was strongly and independently associated with greater dependence in ADL domains, particularly for instrumental activities. CONCLUSIONS: Although telephone-based approaches to neuropsychological assessment are not ideal, these data provide support for the feasibility, internal consistency, and preliminary validity of this method in a consecutive clinical series of PLWH. The direct comparability of telephone-based and in-person neuropsychological assessments remains to be determined by prospective, counterbalanced study designs examining both PLWH and seronegative individuals.

RESUMO

PURPOSE: Despite substantially higher prevalence of depression among people living with HIV/AIDS (PLWHA), few data exist on the incidence and correlates of depression in this population. This study assessed the effect of HIV infection, age, and cohort period on the risk of developing depression by sex among older U.S. Medicare beneficiaries. METHODS: We constructed a retrospective matched cohort using a 5% nationally representative sample of Medicare beneficiaries (1996-2015). People with newly diagnosed (n = 1309) and previously diagnosed (n = 1057) HIV were individually matched with up to three beneficiaries without HIV (n = 6805). Fine-Gray models adjusted for baseline covariates were used to assess the effect of HIV status on developing depression by sex strata. RESULTS: PLWHA, especially females, had higher risk of developing depression within five years. The relative subdistribution hazards (sHR) for depression among three HIV exposure groups differed between males and females and indicated a marginally significant interaction (p = 0.08). The sHR (95% CI) for newly and previously diagnosed HIV (vs. people without HIV) were 1.6 (1.3, 1.9) and 1.9 (1.5, 2.4) for males, and 1.5 (1.2, 1.8) and 1.2 (0.9, 1.7) for females. The risk of depression increased with age [sHR 1.3 (1.1, 1.5), 80 + vs. 65-69] and cohort period [sHR 1.3 (1.1, 1.5), 2011-2015 vs. 1995-2000]. CONCLUSIONS: HIV infection increased the risk of developing depression within 5 years, especially among people with newly diagnosed HIV and females. This risk increased with older age and in recent HIV epidemic periods, suggesting a need for robust mental health treatment in HIV primary care.

RESUMO

Creativity can help people to innovate, overcome obstacles, and successfully navigate challenges in daily life. Some aspects of creativity rely on the prefrontostriatal loops and executive functions, which can be compromised in persons with HIV (PWH). This pilot study examined whether neuropsychological functioning plays a role in creativity in PWH. A consecutive series of 41 PWH who were referred to an urban neuropsychology clinic in southeastern Texas were enrolled. Participants completed the Abbreviated Torrance Test for Adults (ATTA) to measure creativity, from which standardized creativity scores of fluency, originality, elaboration, and flexibility were derived. Participants also completed several measures of everyday functioning and a brief clinical neuropsychological battery measuring executive functions, motor skills, memory, and visuoconstruction. Global neuropsychological functioning showed a large, positive association with ATTA creativity performance that did not vary meaningfully by creativity domain and was independent of premorbid IQ. ATTA creativity scores were not associated with any measure of everyday functioning. Findings from this pilot study suggest that higher levels of neuropsychological functioning may support multiple dimensions of creativity in adults with HIV disease. Future studies might examine whether creativity moderates the association between HIV-associated neurocognitive impairment and various health behaviors (e.g., adherence, appointment attendance).

RESUMO

OBJECTIVE: Despite disproportionally high prevalence of HIV and depression in persons with disabilities, no data have been published on the incidence and correlates of depression in Medicare beneficiaries with disabilities. We assessed the effect of HIV infection on developing depression in this population. DESIGN: We conducted a retrospective matched cohort study using a 5% sample of Medicare beneficiaries who qualified for disability coverage (1996-2015). METHODS: Beneficiaries with incident ( n  = 2438) and prevalent ( n  = 5758) HIV were individually matched with beneficiaries without HIV (HIV-, n  = 20 778). Fine-Gray models with death as a competing risk were used to assess the effect of HIV status, age, and cohort period on developing depression by sex strata. RESULTS: Beneficiaries with HIV had a higher risk of developing depression within 5 years ( P  < 0.0001). Sex differences were observed ( P  < 0.0001), with higher subdistribution hazard ratios (sHR) in males with HIV compared with controls. The risk decreased with age ( P  < 0.0001) and increased in recent years ( P  < 0.0001). There were significant age-HIV ( P  = 0.004) and period-HIV ( P  = 0.006) interactions among male individuals, but not female individuals. The sHR was also higher within the first year of follow-up among male individuals, especially those with incident HIV. CONCLUSION: Medicare enrollees with disabilities and HIV had an increased risk of developing depression compared to those without HIV, especially among males and within the first year of HIV diagnosis. The HIV-depression association varied by sex, age, and cohort period. Our findings may help guide screening and comprehensive management of depression among subgroups in this vulnerable population.

RESUMO

BACKGROUND: Despite a growing call to train clinicians in interpersonal communication skills, communication training is either not offered or is minimally effective, if at all. A critical need exists to develop new ways of teaching communication skills that are effective and mindful of clinician time pressures. We propose a program that includes real-time observation and video-based coaching to teach clinician communication skills. In this study, we assess acceptability and feasibility of the program using clinician interviews and surveys. METHODS: The video-based coaching intervention targets five patient-centered communication behaviors. It uses trained communication coaches and live feed technology to provide coaching that is brief (less than 15 min), timely (same day) and theory-informed. Two coaches were trained to set up webcams and observe live video feeds of clinician visits in rooms nearby. As coaches watched and recorded the visit, they time stamped illustrative clips in real time. Video clips were a critical element of the program. During feedback sessions, coaches used video clips to promote discussion and self-reflection. They also used role play and guided practice techniques to enforce new tips. Clinicians included residents (n = 15), fellows (n = 4), attending physicians (n = 3), and a nurse practitioner (n = 1) at two primary care clinics in Houston, Texas. We administered surveys to clinicians participating in the program. The survey included questions on quality and delivery of feedback, and credibility of the coaches. We also interviewed clinicians following the intervention. We used rapid analysis to identify themes within the interviews. RESULTS: Survey measures showed high feasibility and acceptability ratings from clinicians, with mean item scores ranging from 6.4 to 6.8 out of 7 points. Qualitative analysis revealed that clinicians found that 1) coaches were credible and supportive, 2) feedback was useful, 3) video-clips allowed for self-reflection, 4) getting feedback on the same day was useful, and 5) use of real patients preferred over standardized patients. CONCLUSIONS: Video-based coaching can help clinicians learn new communication skills in a way that is clinician-centered, brief and timely. Our study demonstrates that real-time coaching using live feed and video technology is an acceptable and feasible way of teaching communication skills.

RESUMO

BACKGROUND: The signal-to-cutoff (S/CO) ratio of the HIV antigen/antibody test may help immediately to differentiate true-positive results from false-positive results, which may be particularly useful in time-sensitive circumstances, such as when providing emergency department (ED) care. SETTING: Seven US EDs with HIV screening programs using HIV antigen/antibody assays. METHODS: This cross-sectional study of existing data correlated S/CO ratios with confirmed HIV status. Test characteristics at predetermined S/CO ratios and the S/CO ratio with the best performance by receiver operator characteristic (ROC) curve were calculated. RESULTS: Of 1035 patients with a reactive HIV antigen/antibody test, 232 (22.4%) were confirmed HIV-negative and 803 (77.6%) were confirmed HIV-positive. Of the 803 patients, 713 (88.8%) experienced chronic infections and 90 (11.2%) experienced acute infections. S/CO ratios were greater for HIV-positive (median 539.2) than for HIV-negative patients (median 1.93) (P < 0.001) and lower for acute infection (median 22.8) than for chronic infection (median 605.7) (P < 0.001). All patients with an S/CO ratio < 1.58 (n = 93) were HIV-negative (NPV 100%), and nearly all with an S/CO ≥ 20.7 (n = 760) (optimal level by ROC analysis) were HIV-positive (PPV 98.6%). Of patients with S/CO values between 1.58 and 20.7 (n = 182), 29.7% were HIV-positive. CONCLUSIONS: The S/CO ratio may be used in real time to classify most ED patients as almost certain to be either HIV-positive or HIV-negative long before nucleic acid confirmatory testing is available. When combined with clinical judgment, this could guide preliminary result disclosure and management.

RESUMO

We conducted a prospective cohort study of 450 patients new to an HIV clinic in Houston, TX, to examine the roles of life stressors and initial care experiences in predicting being lost to follow-up in the first year of care. Patients completed a self-administered survey following their initial provider visit. In logistic regression models, patients who reported better experiences with the HIV provider at the first visit were less likely to be lost to follow-up at 6 months (aOR = 0.866, p = 0.038) and 12 months (aOR = 0.825, p = 0.008). Patients with a higher burden of stressful life events were more likely to be lost to follow-up at 6 months (aOR = 1.232, p = 0.037) and 12 months (aOR = 1.263, p = 0.029). Assessments of patient experience and life stressors at the initial visit have potential to predict patients at risk of dropping out of care.

RESUMO

BACKGROUND: Identification of people with HIV from electronic health record (EHR) data is an essential first step in the study of important HIV outcomes, such as risk assessment. This task has been historically performed via manual chart review, but the increased availability of large clinical data sets has led to the emergence of phenotyping algorithms to automate this process. Existing algorithms for identifying people with HIV rely on a combination of International Classification of Disease codes and laboratory tests or closely mimic clinical testing guidelines for HIV diagnosis. However, we found that existing algorithms in the literature missed a significant proportion of people with HIV in our data. OBJECTIVE: The aim of this study is to develop and evaluate HIV-Phen, an updated criteria-based HIV phenotyping algorithm. METHODS: We developed an algorithm using HIV-specific laboratory tests and medications and compared it with previously published algorithms in national and local data sets to identify cohorts of people with HIV. Cohort demographics were compared with those reported in the national and local surveillance data. Chart reviews were performed on a subsample of patients from the local database to calculate the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the algorithm. RESULTS: Our new algorithm identified substantially more people with HIV in both national (up to an 85.75% increase) and local (up to an 83.20% increase) EHR databases than the previously published algorithms. The demographic characteristics of people with HIV identified using our algorithm were similar to those reported in national and local HIV surveillance data. Our algorithm demonstrated improved sensitivity over existing algorithms (98% vs 56%-92%) while maintaining a similar overall accuracy (96% vs 80%-96%). CONCLUSIONS: We developed and evaluated an updated criteria-based phenotyping algorithm for identifying people with HIV in EHR data that demonstrates improved sensitivity over existing algorithms.

RESUMO

Background: The rapid spread of the SARS-CoV-2 pandemic obstructed human subjects research, including our own randomized hybrid type 2 effectiveness-implementation trial comparing multidisciplinary HIV care delivered by video telehealth to home (VTH) versus in-person delivery. Methods: Given the Veteran Health Administration's extensive telehealth infrastructure and our team's expertise in personalized implementation of virtual treatments (PIVOT), we shifted our focus to meet the immediate needs of our primary study site (implementation). Our implementation team began training the interdisciplinary infectious diseases clinical team in VTH after declaration of the pandemic in March 2020. We pivoted from a randomized clinical trial recruitment and supported modifications in clinic processes by introducing patients to VTH through personalized telephone calls and mailed brochures to inform them of telehealth options during the pandemic. Adaptations were made to provider locations, with some providers delivering care remotely from home and others delivering virtual care from the clinic. We also modified the external and internal facilitator roles to allow external facilitators to provide one-on-one training, troubleshooting assistance, and delivery of necessary equipment. Results: Within 6 weeks of the emergency declaration of the pandemic, 100% of providers (n = 27) had conducted at least one appointment, with 24.1% (n = 124) of unique patients using VTH. Despite challenges, we capitalized on temporary mandates to assist providers in delivering care virtually. Given our successes, we encourage researchers to be flexible and seek alternative approaches to preserve research efforts in extenuating circumstances.

RESUMO

OBJECTIVE: People with HIV infection experience excessive mortality compared with their noninfected counterparts. It is unclear whether the impact of HIV infection on mortality varies by comorbidities or whether sex difference exists in this relationship. This study assessed the effect of newly diagnosed HIV infection on overall mortality among Medicare beneficiaries for both disabled and older adults (≥65 years old) based on their original entitlement. METHODS: We constructed a retrospective matched cohort using a 5% nationally representative sample of Medicare beneficiaries between 1996 and 2015. People with incident HIV diagnoses were individually matched to up to three controls based on demographics. Cox proportional hazards models adjusted for baseline demographics and comorbidities were used to assess the effect of HIV status on survival among four disabled groups by sex strata. Within each stratum, interactions between comorbidity variables and HIV status were examined. RESULTS: People with HIV, especially older women, had a higher prevalence of baseline comorbidities than controls. HIV--mortality association varied according to sex in older adults (P = 0.004). Comorbidity--HIV interactions were more pronounced in disabled groups (P < 0.0001). People with HIV with more chronic conditions had a less pronounced increase in the risk of death than those with fewer conditions, compared with uninfected controls. CONCLUSION: Medicare enrollees with newly diagnosed HIV had more prevalent baseline comorbidities and were at higher risk of death than people without HIV. HIV infection has a more pronounced effect among those with fewer comorbidities. Sex differences in HIV--mortality association exist among older Medicare enrollees.

RESUMO

BACKGROUND: Interventions that target anxiety/depressive symptoms in the context of smoking treatment have shown promise irrespective of psychiatric diagnosis. Yet, these tailored treatments are largely absent for persons who smoke and are living with HIV (SLWH). OBJECTIVE: To evaluate a novel, smoking cessation intervention that addresses anxiety/depression and HIV-related health (QUIT) against a time-matched control (TMC) and a standard of care (SOC) condition. METHODS: SLWH (N = 180) will be recruited and enrolled from 3 medical clinics in Boston, MA, and Houston, TX. The trial will consist of a baseline assessment, a 10-week intervention/assessment period, and follow-up assessments, accounting for a total study duration of approximately 8 months. All participants will complete a baseline visit and a pre-randomization standardized psychoeducation visit, and will then be randomized to one of three conditions: QUIT, TMC, or SOC. QUIT and TMC will consist of nine 60-min, cognitive behavioral therapy-based, individual weekly counseling sessions using standard smoking cessation counseling; additionally, QUIT will target anxiety and depressive symptoms by addressing underlying mechanisms related to mood and quit difficulty. SOC participants will complete weekly self-report surveys for nine weeks. All participants will be encouraged to quit at Session 7 and will be offered nicotine replacement therapy to help. CONCLUSIONS: QUIT is designed to improve smoking cessation in SLWH by addressing anxiety and depression and HIV-related health issues. If successful, the QUIT intervention would be ready for implementation and dissemination into "real-world" behavioral health and social service settings consistent with the four objectives outlined in NIDA's Strategic Plan.

RESUMO

OBJECTIVE: Spaced retrieval practice (SRP) and self-generation are among the most replicated and effective mnemonic strategies in the cognitive psychology literature, but their benefits have not yet been realized in healthcare settings. This study used a randomized, between-subjects design to examine the hypothesis that SRP with a self-generation booster can improve memory for health-related information among clinically referred persons with HIV (PWH), who often have difficulty acquiring new health knowledge. METHOD: A consecutive series of 41 PWH referred to a county-funded urban neuropsychology clinic were enrolled. Participants were randomly assigned to learn four statements about the treatment of a mock infectious disease in either a massed study control condition (n = 20) or an SRP condition (n = 21) in which they received two distributed free recall training tests supplemented with self-generation for missed items. The primary outcome was participants' free recall of the four treatment statements after a 20-minute delay filled with nonverbal tests. RESULTS: PWH participants in the SRP condition were four times more likely than controls to recall at least one treatment statement at the 20-minute delay. SRP was not related to post-test recognition or health-related decision-making performance but was associated with moderately better self-efficacy for decision-making. CONCLUSIONS: Findings from this pilot study show the potential of SRP with a self-generation booster to improve learning and memory for health-related information among PWH in clinic.

RESUMO

The study examines the reliability and validity of a 3-item self-report adherence measure among people with HIV (PWH) experiencing homelessness, substance use, and mental health disorders. 336 participants were included from nine sites across the US between September 2013 and February 2017. We assessed the validity of a self-report scale for adherence to antiretroviral therapy by comparing it with viral load (VL) abstracted from medical records at baseline, 6, 12, and 18 months. The items had high internal consistency (Cronbach's alpha coefficients at each time point were > 0.8). The adherence scale scores were higher in the group that achieved VL suppression compared to the group that did not. The c-statistic for the receiver-operating characteristic curves pooled across time points was 0.77 for each adherence sub-item and 0.78 for the overall score. The self-report adherence measure shows good internal consistency and validity that correlated with VL suppression in homeless populations.
