Association between health literacy and HIV treatment adherence: further evidence from objectively measured medication adherence

Treatment adherence: A Concept Analysis Using the Walker & Avant Method

Purpose

To clarify the meaning of treatment adherence and identify its attributes, antecedents, consequences, and empirical referents.

Design

A concept analysis.

Methods

Walker and Avant's method was used to analyze treatment adherence. PubMed, Web of Science, Wiley Online Library, and EBSCO databases were searched from 2013 to 2023. The PRISMA 2020 checklist was used.

Results

Seventeen studies were included in this analysis. The defining attributes were the ability to comply with the treatment, consistency in the treatment plan, communication with the healthcare provider, and willingness to treat. Antecedents included multiple medicines, lifestyle changes, illness perceptions and beliefs, and long-term treatment. The outcomes included treatment success, improved long-term treatment, and improved clinical outcomes.

Conclusion

Treatment adherence is a positive reaction of a patient to have the ability to comply with the treatment, consistency in the treatment plan, communication with the healthcare provider, and willingness to treat. This study proposes a detailed definition, attributes, antecedents, consequences, and empirical referents for treatment adherence. It is instructive to clinical nursing of treatment adherence, can be extended to various diseases, helps to improve clinical nursing practice regarding treatment adherence, and contribute to improving human health.

The Relationship of Health Literacy to Health Outcomes Among Individuals With Traumatic Brain Injury: A Traumatic Brain Injury Model Systems Study

OBJECTIVE

To examine the associations between health literacy and health outcomes among individuals with traumatic brain injury (TBI) at least a year post-injury.

SETTING

Community following discharge from inpatient rehabilitation.

PARTICIPANTS

A total of 205 individuals with complicated mild to severe TBI who completed a TBI Model Systems National Database follow-up interview and a web-based health literacy measure.

DESIGN

A multicenter, cross-sectional, observational study.

MAIN MEASURES

The Health Literacy Assessment Using Talking Touchscreen Technology (Health LiTT), number of comorbid conditions (Medical and Mental Health Comorbidities Interview [MMHCI]), perceived physical and mental health (PROMIS Global Physical and Mental Health subscales), Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7).

RESULTS

After controlling for sociodemographic, injury, cognition, and time post-injury, adequate health literacy was associated with higher odds of greater perceived physical health compared with participants with marginal/inadequate health literacy (odds ratio = 4.10; CI = 1.52-11.70]. Participants with inadequate/marginal health literacy had 3.50 times greater odds of depression (PHQ-9 ≥ 10) compared with those with adequate health literacy. Participants 45 years and older reported a greater number of MMHCI physical health conditions, but fewer MMHCI mental health conditions and GAD-7 anxiety symptoms compared with those who were younger. Non-Hispanic White participants and those with mild/moderate TBI were more likely to report a greater number of MMHCI mental health conditions compared with non-Hispanic Black participants or those with severe TBI. Greater time post-injury was associated with greater number of chronic physical and mental health conditions, and less odds of good-to-excellent perceived global mental health.

CONCLUSIONS

Inadequate health literacy is associated with worse perceived physical health and greater depressive symptoms among adults with TBI. Greater efforts are needed to explore the mechanisms by which health literacy influences chronic disease management and mental health after TBI to improve postinjury health status and outcomes, particularly among those with limited health literacy skills.

"I thought it was for guys that did needles": Medication perceptions and lay expertise among medical research participants

INTRODUCTION

Although randomized controlled trials (RCTs) examine "objective" indicators of safety and efficacy of investigational drugs, participants may not perceive study medications as neutral entities. Some medications are imbued with social and cultural meaning, such as stigmatized medications for opioid use disorders. Such perceptions surrounding substance use treatments can extend to the research context and shape RCT participants' experiences with and adherence to study medications.

METHODS

Considering these complexities in substance use research, we conducted a nested qualitative study within a multi-site, pragmatic RCT in Canada testing two treatments (methadone versus buprenorphine/naloxone) for opioid use disorder. Between 2017 and 2020, we conducted 115 interviews with 75 RCT participants across five trial sites in British Columbia, Alberta, Ontario, and Quebec.

RESULTS

Using an abductive coding approach, we characterized participants by their previous experience with medication for opioid use disorder and by their exposure to drug culture and drug scenes. Across these experience types, we identified systematic differences around participants' perceptions of the study medications, sources of information and expertise, and medication stigma.

CONCLUSION

Our findings illustrate the critical importance of social context in shaping medication beliefs and study experiences among people who use drugs, with implications for the conduct of future RCTs in substance use.

Health literacy mediates the effects of educational attainment on online pharmacy navigation skills in older adults with HIV disease

ObjectiveThe Internet serves an increasingly critical role in health behaviors for older adults with chronic medical conditions. Guided by theories of health behaviors and literacy, this study examined whether the relationship between educational attainment and online pharmacy skills in older persons with HIV disease (PWH) is mediated by health literacy. Design: Participants included 98 PWH age 50 and older who completed the Test of Online Pharmacy Skills (TOPS), which required them to navigate an experimenter-controlled online pharmacy to perform several naturalistic tasks (e.g., refill an existing prescription). Participants also completed the Medication-Management Test-Revised (MMT-R). Results: Mediation analyses revealed a significant indirect effect of education on both online pharmacy accuracy and MMT-R, which was fully mediated by health literacy. In contrast, there was no direct or indirect effect of education on online pharmacy speed when health literacy was included as a mediator. Conclusion: Health literacy plays an important role in the relationship between years of education attained and the ability of older PWH to successfully navigate online pharmacy tasks and manage their medications. Future studies might examine whether interventions to improve electronic health literacy among older PWH who have lower educational attainment have beneficial effects on online health behaviors.

Association of Health Literacy With the Prevalence of Cardiovascular Diseases and Their Risk Factors Among Older Japanese Health Management Specialists

In this study, we aimed to determine the association between health literacy and the development of cardiovascular diseases (CVDs), among an older population. This cross-sectional study was conducted among Japanese health management specialists (N = 593). Higher levels (communicative and critical) of health literacy and CVD risk factors (diabetes mellitus, hypertension, dyslipidemia, and obesity) were measured. The mean patient age was 71.3 years. Logistic regression analyses showed statistically significant associations between higher levels of health literacy and the prevalence of CVDs (β coefficient = -.091, p < .05) and metabolic risk factors (β coefficient = -.084, p < .01). There was a statistically significant association between health literacy and the count of CVDs (and its risk factors) (β coefficients of Poisson regression = -.036, p < .05). The results show health literacy to be fundamentally related to low prevalence of cardiovascular diseases and their associated metabolic risk factors.

"I Haven't Been Ill, I Know It's There": a Case Study Examination of the Social, Behavioral, Clinical, and Structural Factors that Contribute to Sustained Viremia Among Women Living with HIV

Compared to their HIV-seropositive male counterparts, HIV-seropositive women are less likely to achieve and retain viral suppression (VS). Data regarding the social, behavioral, clinical, and structural factors that facilitate or impede viral suppression among HIV-seropositive women is needed. This study aims to examine HIV-seropositive women's perceptions regarding factors that contribute to their HIV treatment decisions. Two case studies describe the HIV treatment decision-making of two never suppressed, HIV-seropositive women aged 65 and 54. The framework method of analysis was employed to obtain a descriptive overview of three interrelated areas of inquiry: (1) the meanings women give to VS; (2) social, behavioral, clinical, and structural obstacles related to HIV medication adherence; and (3) women's perceptions of what they need to achieve and sustain (VS). The meaning of VS for both women is influenced by how they currently feel. Women's general feeling of wellness detracts from any sense of urgency that may be associated with engaging in HIV treatment. Mistrust of medical providers and unstable housing/unemployment pose as obstacles to medication adherence. Finally, women's accounts of what they need to achieve and remain virally suppressed are influenced by a gap in understanding related to HIV treatment. HIV clinicians should routinely measure their patients' HIV health literacy to ensure patients understand when to begin and why they should continue an HIV treatment regimen. To increase their capacity to provide appropriate HIV care, providers should take into consideration how patients' life experiences and social locations influence their HIV treatment decision-making.

Evaluation of a decision aid for the treatment of depression among college students

Objective: Depression, and its treatment, is a concern among college students. Research indicates decision aids (DA) improve patients' treatment knowledge, decision making, and decisional conflict; however, it is unknown whether they are helpful for disseminating depression treatment information to college students. This study evaluated a DA for depression and its impact on college students' knowledge and treatment decision making. Methods: College students (N = 144) completed questionnaires pre-, post-, and at 1-month follow-up after reviewing an evidence-based DA for depression. Results: Participants rated the DA as highly acceptable and useful, and their knowledge increased at post-treatment and follow-up. However, treatment option presentation order influenced decision making. Conclusions: This DA is a useful and acceptable decision-making tool, and increased knowledge of depression and its treatment among college students. This study proposes a novel tool for educating college students about depression treatment, furthering our understanding of factors influencing treatment preferences.

A Systematic Review of Factors Critical for HIV Health Literacy, ART Adherence and Retention in Care in the U.S. for Racial and Ethnic Minorities

Despite advances in antiretroviral treatment (ART), the HIV epidemic persists in the United States (U.S.), with inadequate adherence to treatment and care a major barrier to ending the epidemic. Health literacy is a critical factor in maximizing ART adherence and healthcare utilization, especially among vulnerable populations, including racial and ethnic minorities. This U.S-based systematic review examines psychosocial variables influencing health literacy among persons with HIV (PWH), with a focus on racial and ethnic minorities. Although findings are limited, some studies showed that HIV-related stigma, self-efficacy, and patient trust in providers mediate the relationship between health literacy and both ART adherence and HIV care retention. To inform effective, equitable health literacy interventions to promote adherence to HIV treatment and care, further research is needed to understand the factors driving the relationship between health literacy and HIV outcomes. Such work may broaden our understanding of health literacy in the context of racial equity.

ART uptake and adherence among female sex workers (FSW) globally: A scoping review

We conducted the first scoping literature review on ART uptake and adherence among Female Sex Workers (FSW), following PRISMA-ScR guidelines. Searches were conducted in PubMed, Embase, CINAHL, PsycInfo, and Sociological Abstracts. Eligibility criteria included: reporting an ART uptake or adherence result among FSW aged 18 or older; peer-reviewed; published in English between 1996 and 2018. Our search identified 6,735 studies; 30 met eligibility requirements. ART uptake ranges from 0 to 100% and adherence ranges from 50-90%, depending on measurement methods. Uptake and adherence influencing factors are mapped onto a social ecological model (SEM). Knowledge and beliefs, substance use, food insecurity and sex-work engagement were negatively associated, while older age, relationships and social support were positively associated with ART uptake and adherence. Standardised methods to measure uptake and adherence prevalence must be established for data comparison. Evidence regarding ART uptake and adherence barriers and facilitators span multiple SEM levels, although more research is needed regarding structural and occupational level influencers. Results suggest that the multi-level ART uptake and adherence barriers faced by FSW require complex multi-level evidence-based interventions. Study findings can inform ART interventions, future research, and offer guidance to other support services with FSW, such as PrEP interventions.

Home Environment Influence on Adolescent Health Literacy

Adolescent health disparities are influenced by individuals' health literacy. To date, the only known household factors to influence adolescent health literacy (AHL) are social capital factors of parental health literacy, parent education, and household income. Therefore, the purpose of this study was to expand the understanding of household factors that influence AHL for future interventions. A sample of 105 adolescents and their parents completed an online survey. Home environment variables included family communication, family involvement, and books in the home. A quantitative analysis of correlations and regression was employed to explore the relationship between AHL and household factors. Findings from this study suggest that parental health literacy is the best-known household facilitator of AHL. Family communication and family involvement were not correlated with AHL. The number of books in the home was correlated with AHL. A good understanding of the factors influencing AHL is necessary for developing interventions. These findings continue to lend support that AHL is heavily associated with parental health literacy. Based on the salience of these findings in the research, future health literacy interventions should consider incorporating a parent/caregiver component. Yet, what remains unknown is the mechanism between AHL and parental health literacy.

The effect of visual interventions on illness beliefs and medication adherence for chronic conditions: A scoping review of the literature and mapping to behaviour change techniques (BCTs)

BACKGROUND

Maintaining health with chronic conditions often involves taking multiple medications; however, approximately 50% of patients with chronic conditions are non-adherent to medication. Patients' illness beliefs inform health behaviour, including medication-taking. Research has shown that visuals accompanying health information increased patient comprehension and the accuracy of illness perceptions. To date, the influence of visuals on illness beliefs and medication adherence has not been comprehensively reviewed.

OBJECTIVES

The review aimed to collate available literature on visualisation interventions for illness beliefs and medication adherence in chronic conditions and identify key intervention characteristics.

METHODS

A scoping review was conducted according to recommended guidelines and the PRISMA-ScR statement. Searches used keywords relating to 'illness', 'visual', 'adherence', 'illness perception', 'intervention', and 'medication'. Six databases were searched from inception to 2019; reference-list searching provided additional articles. Articles were included if the study population had a chronic health condition, the intervention included a visual element, had a measure of illness beliefs or medication adherence. Data regarding intervention characteristics and outcomes were extracted. Behaviour change techniques (BCTs) were identified to provide further insight into intervention characteristics.

RESULTS

Initially, 18,012 articles were identified. Screening led to 293 full-text articles, ultimately resulting in 45 studies for final analysis. Forty-four were quantitative studies, 1 was qualitative. Studies were grouped into those using visuals to conceptualise a condition, medication reminders and educational interventions. Almost two-thirds of visual interventions were effective post-intervention, 3 sustained post-1-year, although many studies only assessed impact immediately post-intervention. BCTs from 'Natural consequences', 'Socialsupport' and 'Feedback and monitoring' categories were prevalent in effective interventions for both outcomes, particularly the 'Salience of consequences' BCT.

CONCLUSIONS

This comprehensive scoping review found that visual interventions can positively influence illness beliefs and medication adherence. These findings highlight the need to further evaluate the impact and sustainability of visual interventions.

HIV and antiretroviral treatment knowledge gaps and psychosocial burden among persons living with HIV in Lima, Peru

This study aims to describe knowledge on HIV and antiretroviral (ARV) treatment and psychosocial factors among people living with HIV (PLWH) in Lima, Perú, to explore characteristics associated to this knowledge, and determine its impact on sustained viral suppression. A cross-sectional survey was conducted among 171 PLWH at the largest referral health care center in Lima. The psychosocial factors measured were depression, risk of alcoholism, use of illegal drugs and disclosure. A participant had "poor knowledge" when less than 80% of replies were correct. Sustained viral suppression was defined as two consecutive viral loads under 50 copies/mL. A total of 49% and 43% had poor HIV and ARV knowledge respectively; 48% of the study population screened positive for depression and 27% reported feeling unsupported by the person they disclosed to. The largest gaps in HIV and ARV knowledge were among 98 (57%) that did not recognize that HIV increased the risk of cancer and among 57 (33%) participants that did not disagree with the statement that taking a double dose of ARV if they missed one. Moderate depression was significantly associated to poor HIV and ARV knowledge. Non-disclosure and being on ARVs for less than 6 months were associated with not achieving sustained viral suppression. Our findings highlight important HIV and ARV knowledge gaps of PLWH and a high burden of psychosocial problems, especially of depression, among PLWH in Lima, Peru. Increasing knowledge and addressing depression and disclosure could improve care of PLWH.

Feasibility and Acceptability of an Adolescent-Friendly Rap Video to Improve Health Literacy Among HIV-Positive Youth in Urban Peru

Clinical outcomes among adolescents living with HIV (ALHIV) might be improved by interventions aimed at addressing limited health literacy. We developed a Spanish-language rap video on HIV concepts and examined its acceptability and feasibility as a learning tool among ALHIV in Lima, Peru. Twenty-eight ALHIV receiving care at an urban pediatric hospital and ten stakeholders engaged in the care of adolescents watched the video. Adolescents completed a pre- and post-video questionnaire. We conducted focus groups with ALHIV and in-depth interviews with stakeholders and analyzed transcripts to identify themes. ALHIV described concepts of CD4 cell count and viral load as they were portrayed. Participants reported the video was relatable, accessible, and provided hope that ALHIV could lead healthy lives and advocated for future videos to address topics such as transmission and sexual health. Questionnaires indicated some improvement in viral load knowledge. An HIV health literacy music video intervention was feasible to implement and accepted by ALHIV and their healthcare providers. Communicating HIV knowledge via music videos may be promising; further study is needed to optimize implementation.

Smartphone-based incentives for promoting adherence to antiretroviral therapy: A randomized controlled trial

•

Contingency management (CM) intervention can promote adherence to ART.

•

CM for ART adherence can be delivered via a smartphone platform.

•

Smartphone CM reduces barriers to adoption of CM relative to in-person CM.

•

Low-income people with HIV found smartphone CM to be acceptable and easy to use.

•

CM produced detectable ART adherence improvements despite high baseline levels.

Antiretroviral therapy can improve the lives of people living with HIV and reduce the rate of transmission. However, high levels of adherence are required. Some people living with HIV, including people who use drugs, are at elevated risk for non-adherence. Contingency management is a promising intervention for promoting adherence to antiretroviral therapy. Barriers to adoption of contingency management include lack of provider expertise and implementation effort. To address these barriers, a smartphone-based adherence intervention was developed. HIV + people with a substance use disorder were required to submit video selfies of medication consumption that met validity criteria. Monetary incentives were delivered to participants via reloadable debit cards, contingent upon a valid video. The intervention was evaluated in a small (n = 50) randomized controlled trial. Intervention participants submitted 75% of possible videos, and 81% of videos met validity criteria, indicating a high level of usability. Participants also rated the intervention as highly acceptable. Adherence was measured as the percent of participants who achieved a 95% adherence threshold, and also as the overall percent of days in which participants were adherent to their antiretroviral therapy. The former showed a significant effect for group, (p = .034) but this was not maintained when adjusting for stratification variables as covariates (p = .094). The latter measure showed a significant group × time interaction. Smartphone-based contingency management is a promising method for promoting adherence to antiretroviral therapy. Assessing the cost-benefit of the intervention and development of strategies for long-term adherence are priorities for future research.

Treatment Satisfaction and Its Associated Factors of Dolutegravir Based Regimen in a Resource Limited Setting

INTRODUCTION

Treatment satisfaction is patient's evaluation of the process of taking the medication and its use. Currently dolutegravir based regimen is first-line agent for treatment of human immunodeficiency virus. But evidence is scarce regarding treatment satisfaction. Thus, the aim of the current study was to assess treatment satisfaction and associated factors of dolutegravir based regimen among adult human immunodeficiency virus patients attending at Debre Markos referral 2020.

METHODS

Institutional-based cross-sectional study was conducted. A systematic random sampling technique was used to collect data from June 25 to August 25, 2020 at Debre Markos referral hospital. It was entered into Epi Info and exported to SPSS version 23 for analysis. Bivariable and multivariable logistic regression was used to identify factors. Variables with p<0.05 were considered as statistically significant.

RESULTS

From a total of 359, 349 participants (97.2%) responded to the study. In this study, 70.5% of participants reported higher treatment satisfaction. Monthly average income of ≥3500 birr (AOR: 2.88; 95% CI: 1.26, 6.58), 1600-2500 birr (AOR: 2.47; 95% CI: 1.11, 5.48), 800-1600 birr (AOR: 3.11; 95% CI: 1.31, 7.37), positive belief about medications (AOR: 3.05; 1.76, 5.28), having a discussion with health care providers (AOR: 3.05, 95% CI: 1.58, 5.88), patients without concurrent medication (AOR: 7.72, 95% CI: 3.29, 18.07), and being male (AOR: 2.10, 95% CI: 1.14, 3.87) were associated with treatment satisfaction.

CONCLUSION

Overall, dolutegravir based regimen showed high treatment satisfaction. Monthly income, positive beliefs about medications, discussing about treatment options, sex and concurrent medications were associated with treatment satisfaction. Thus, it is crucial to improve treatment satisfaction by promoting positive belief towards medication and also by engaging patients in treatment decisions.

Drug Use and Life Chaos as Potential Factors Contributing to HIV Viral Load among People with Lower Health Literacy

Lower health literacy is associated with poorer health outcomes in people living with HIV (PLWH), but the explanatory mechanisms for these associations are not well understood. Factors such as drug use and life chaos may at least in part account for the relationship between lower health literacy and poor health outcomes. The current study tested the hypothesis that lower health literacy would predict drug use, which in turn would predict life chaos, and that all three factors would be related to poorer heath, defined by higher concentrations of HIV viremia. Methods: Patients receiving HIV care (N = 251) at an HIV clinic in the southeastern United States completed computerized interviews and permission to access their medical records. Process modeling tested direct and indirect effects of all variables in a serial mediation model. Results: The direct effects of lower health literacy and drug use were significantly related to HIV viremia. In addition, the indirect effect of health literacy on HIV viremia through drug use was significant. However, results did not demonstrate any effect, direct or indirect, of life chaos on HIV viremia. Conclusion: Findings from this study bolster previous research demonstrating lower health literacy and drug use as barriers to HIV care, and show that lower health literacy impacts HIV viremia, at least in part, through drug use. Interventions aimed to improve HIV treatment outcomes in lower health literacy populations may be enhanced by integrating evidence-based approaches to reducing drug use.

Development of a Diabetes-Focused Print Health Literacy Scale Using the Rapid Estimate of Adult Literacy in Medicine Model

BACKGROUND

A diabetes mellitus (DM)-specific health literacy (HL) measure that focuses on both oral and print HL is needed in clinical and research settings.

OBJECTIVE

The present study developed a psychometrically sound DM-specific HL instrument that measures oral and print HL.

METHODS

We developed the measure in three steps. First, we reviewed clinical guidelines and conducted focus groups with experts to generate items. Next, we conducted a psychometric evaluation of the scale in three language versions (English, Spanish, and Korean). Lastly, we identified and removed items with potential cultural bias and duplicate functions to produce shorter versions of the scale, using item response theory (IRT).

KEY RESULTS

We initially developed an 82-item DM-specific oral HL scale using the Rapid Estimate of Adult Literacy in Medicine (DM-REALM) model. To improve the clinical utility of the DM-REALM, we created shorter forms, a 40-item and 20-item version, and evaluated them by using IRT. All DM-REALM versions had high Cronbach alphas (.985, .974, and .945, respectively) and yielded sufficient convergent validity by positive correlations with existing functional HL scale (r = .49, p < .001), education (r = .14, p = .14 to r = .54, p < .001), and DM knowledge (r = .04, p = .70 to r = .36, p < .001). DM-REALM also demonstrated adequate sensitivity as an intervention evaluation tool that captures the changes induced by an intervention.

CONCLUSIONS

All forms of the DM-REALM tool were reliable, valid, and clinically useful measures of HL in the context of DM care. Both researchers and clinicians can use this tool to assess DM-specific HL across multiple racial and ethnic populations. [HLRP: Health Literacy Research and Practice. 2020;4(4):e237-e249.] PLAIN LANGUAGE SUMMARY: This article reported the process and findings of a newly developed health literacy scale for people with diabetes mellitus using three different language versions. Both long and short versions of the scale demonstrated adequate validity and reliability.

Investigating Health Literacy in Systemic Lupus Erythematosus: a Descriptive Review

PURPOSE OF REVIEW

Inadequate health literacy is common among American adults, but little is known about the impact of health literacy in rheumatic diseases. The purpose of this article is to review studies investigating health literacy and its association with clinical outcomes in systemic lupus erythematosus (SLE).

RECENT FINDINGS

Several validated health literacy measures have been examined in SLE patients. Low health literacy is associated with worse patient-reported outcomes and lower numeracy with higher disease activity. Two studies found no association of low health literacy with medication adherence. One randomized controlled trial tested a medication decision aid among patients with low health literacy. We found a paucity of studies exploring health literacy in SLE. Low health literacy is associated with worse patient-reported outcomes and limited numeracy with higher disease activity in SLE. Further studies are needed exploring the impact of low health literacy on clinical outcomes and the effectiveness of literacy-sensitive interventions.

Gender, HIV knowledge and prevention attitudes among adolescents living with HIV participating in an economic empowerment intervention in Uganda

HIV disproportionately affect adolescent girls and young women in sub-Saharan Africa. In Uganda, the HIV prevalence is four times higher in adolescent girls compared to boys. This study examined gender, HIV general and clinical knowledge, and prevention attitudes among adolescents living with HIV in Uganda. Data from a cluster randomized clinical trial were analyzed. A total of 702 adolescents (average age of 12.4) were randomized to either a control arm receiving bolstered standard of care or the treatment arm receiving bolstered standard of care plus a family economic empowerment intervention to support medication adherence. Ordinary Least Squares models that adjust for clustering of adolescents within health clinics were conducted. No gender differences were observed in HIV knowledge and prevention attitudes at baseline. However, at 12-months follow-up, boys were more likely than girls to report correct HIV general knowledge (d = 0.21), clinical knowledge (d = 0.48), and favorable prevention attitudes (d = 0.27). The intervention was not associated with any of the outcomes. Given the high HIV prevalence among adolescents, specifically girls, there is need to develop and/or tailor existing programs and interventions that equip adolescent girls with comprehensive knowledge and prevention attitudes, that are culturally appropriate, to reduce HIV transmission and reinfection within this population.

Acceptability of a trial of vaginal progesterone for the prevention of preterm birth among HIV-infected women in Lusaka, Zambia: A mixed methods study

Antenatal progesterone prevents preterm birth (PTB) in women with a short cervix or prior PTB in daily vaginal or weekly injectable formulations, respectively. Neither has been tested for the indication of maternal HIV, which is associated with an elevated risk of PTB. The Vaginal Progesterone (VP) Trial was a pilot feasibility study of VP to prevent HIV-related PTB in Lusaka, Zambia. Using mixed methods, we concurrently evaluated the acceptability of the trial and the study product among participants. Over a 1-year period, we enrolled 140 pregnant women living with HIV into a double-masked, placebo-controlled, randomized trial of daily self-administered VP or placebo. We administered an endline questionnaire to all participants and conducted in-depth interviews with 30 participants to assess barriers and facilitators to uptake and retention in the trial and to study product adherence. All interviews were audiotaped, transcribed, translated into English as needed, and independently coded by two analysts to capture emerging themes. Of 131 participants who completed the questionnaire, 128 (98%) reported that nothing was difficult when asked the hardest part about using the study product. When given a hypothetical choice between vaginal and injectable progesterone, 97 (74%) chose vaginal, 31 (24%) injectable, and 3 (2%) stated no preference. Most interviewees reported no difficulties with using the study product; others cited minor side effects and surmountable challenges. Strategies that supported adherence included setting alarms, aligning dosing with antiretrovirals, receiving encouragement from friends and family, sensing a benefit to their unborn baby, and positive feedback from study staff. Participants who reported preference of a vaginal medication over injectable described familiarity with the vaginal product, a fear of needles and resulting pain, and inconvenience of a weekly clinic visit. Those who would prefer weekly injections cited fewer doses to remember. Perceived barriers to study participation included mistrust about the motivations behind research, suspicion of Satanism, and futility or possible harm from a placebo. We report key influences on acceptability of a randomized trial of VP to prevent PTB among HIV-infected women in Zambia, which should inform methods to promote uptake, adherence, and retention in a full-scale trial.

Disparities in Electronically Monitored Antiretroviral Adherence and Differential Adherence Predictors in Latinx and Non-Latinx White Persons Living with HIV

Antiretroviral therapy (ART) adherence is vital for optimal HIV treatment. However, there is limited ART adherence research on the US Latinx population, who are at increased risk for HIV infection and worse HIV health outcomes. This study examined electronically measured ART adherence (Medication Event Monitoring System) and its association with demographic, clinical, neurocognitive, and sociocultural variables in Latinx and non-Latinx white (NLW) persons living with HIV [PLWH (N = 128)]. Latinx participants demonstrated worse adherence than NLW participants (p = 0.04). Linear regressions revealed different predictors of adherence. Among Latinx participants, recent cocaine use, stress, and, unexpectedly, higher US acculturation predicted worse adherence (ps < 0.05). Among NLW participants, recent cocaine use predicted worse adherence (p < 0.05). Intergroup comparisons within the Latinx group were not conducted due to subsample size. Thus, ethnicity, sociocultural variables, and cocaine use are important considerations for ART adherence, and poor ART adherence may be one pathway explaining worse outcomes in Latinx PLWH. Culturally tailored adherence interventions incorporating substance use treatment, acculturation, and stress management are warranted to improve health outcomes.

An instrument to assess HIV-related knowledge and adjustment to HIV+ status, and their association with anti-retroviral adherence

Background

Findings on the association between health literacy and anti-retroviral (ARV) adherence are inconsistent. Health literacy is usually operationalized with simple tests of basic literacy, but more complex conceptions of health literacy include content knowledge. People living with chronic illness also conceptualize and experience illness in ways other than biomedical or mechanistic models of disease.

Objective

There are no instruments that comprehensively assess knowledge of people living with HIV concerning HIV disease and treatment; or psychological adjustment to being HIV+. Little is known about the relationship between factual knowledge, or positive identification as HIV+, and anti-retroviral (ARV) adherence.

Methods

Formative work with in-depth semi-structured interviews, and cognitive testing, to develop a structured instrument assessing HIV-related knowledge, and personal meanings of living with HIV. Pilot administration of the instrument to a convenience sample of 101 respondents.

Key results

Respondents varied considerably in their expressed need for in-depth knowledge, the accuracy of their understanding of relevant scientific concepts and facts about ARV treatment, and psychological adjustment and acceptance of HIV+ status. Most knowledge domains were not significantly related to self-reported ARV adherence, but accurate knowledge specifically about ARV treatment was (r = 0.25, p = .02), as was an adapted version of the Need for Cognition scale (r = .256, p = .012). Negative feelings about living with HIV (r = .33, p = .0012), and medication taking (r = .276, p = .008) were significantly associated with non-adherence.

Conclusion

The instrument may be useful in diagnosing addressable reasons for non-adherence, as a component of psychoeducational interventions, and for evaluation of such interventions.

Health Literacy Among In-Care Older HIV Diagnosed Persons with Multimorbidity: MMP NYS (Excluding NYC)

Older persons living with diagnosed HIV (PLWDH) are also at risk for age-related chronic conditions. With conflicting results on studies assessing health literacy and durable viral suppression, this study is the first in assessing this relationship using representative data on older in-care HIV-diagnosed persons with multimorbidity. Weighted data collected 2009-2014 from the Medical Monitoring Project (MMP) was used. Health literacy was assessed using the three-item Brief Health Literacy Screen (BHLS). The mean health literacy score was 11.22 (95% CI 10.86-11.59), and the mean multimorbidity was 4.75 (SE = 0.32). After adjusting, health literacy (OR 0.87, 95% CI 0.77-0.99) was found to be significantly associated with durable viral suppression. Adequate health literacy can help with achieving durable viral suppression. For these persons, addressing health literacy might increase their ability to access and navigate the healthcare system, thereby helping them stay engaged and maintain adherence to HIV care.

Evaluation of a Computer-Based HIV Education Program for Adults Living with HIV

This study evaluated a computer-delivered HIV and antiretroviral treatment education program in adults (N = 102) living with detectable HIV viral loads (> 200 copies/mL). The self-paced program provided immediate feedback for responses and financial incentives for responding correctly. The program was divided into three courses and a test of content from all three courses was delivered before and after participants completed each course. Test scores on the content delivered in Courses 1, 2 and 3 improved only after participants completed training on the relevant course. Initial test scores were positively correlated with health literacy and academic achievement; were negatively correlated with viral load; and were lowest for participants living in poverty. Education, academic achievement, and health literacy were related to how much participants learned following each course. Computer-based education is a convenient, effective approach to promoting an understanding of HIV and its treatment.

Implementation of a Routine Health Literacy Assessment at an Academic Medical Center

Limited health literacy is a common but often unrecognized problem associated with poor health outcomes. Well-validated screening tools are available to identify and provide the opportunity to intervene for at-risk patients in a resource-efficient manner. This is a multimethod study describing the implementation of a hospital-wide routine health literacy assessment at an academic medical center initiated by nurses in April 2014 and applied to all adult inpatients. Results were documented in the electronic health record, which then generated care plans and alerts for patients who screened positive. A nursing survey showed good ease of use and adequate patient acceptance of the screening process. Six months after hospital-wide implementation, retrospective chart abstraction of 1,455 patients showed that 84% were screened. We conclude that a routine health literacy assessment can be feasibly and successfully implemented into the nursing workflow and electronic health record of a major academic medical center.

Graphic Warning Labels Affect Hypothetical Cigarette Purchasing Behavior among Smokers Living with HIV

Cigarette pack graphic warning labels (GWLs) are associated with increased knowledge of tobacco-related harms; scant research has evaluated their effects on behavior among vulnerable populations. We used a behavioral economic approach to measure the effects of GWLs and price on hypothetical cigarette purchasing behavior among HIV-positive smokers. Participants (n = 222) completed a cigarette valuation task by making hypothetical choices between GWL cigarette packs at a fixed price ($7.00) and text-only warning label cigarette packs at increasing prices ($3.50 to $14.00; $0.25 increments). More than one-quarter (28.8%) of participants paid more to avoid GWLs. The remaining participants’ purchasing decisions appear to have been driven by price: 69.8% of participants chose the cheaper pack. Across all participants, overall monetary choice value observed for GWL cigarette packs (mean = $7.75) was greater than if choice was driven exclusively by price ($7.00). Most (87.4%) preferred the text-only warning label when GWL and text-only cigarette packs were equally priced. Correlation analysis indicated GWL pack preference was associated with agreement with statements that GWLs would stop individuals from having a cigarette or facilitate thoughts about quitting. These data suggest that GWLs may influence some HIV-positive smokers in such a way that they are willing to pay more to avoid seeing GWLs.

Becoming adherent to a preventive treatment for HIV: a qualitative approach

The clinical trial ANRS-IPERGAY investigated the efficacy of sexual activity-based (i.e. on demand) HIV pre-exposure prophylaxis (PrEP). Using a qualitative method, we analysed the role of adherence as one of the main elements for PrEP effectiveness and its associated determinants. Data were collected in various French ANRS-IPERGAY sites during the double-blind (2012-2014) and open-label study (2015-2016) phases, through two individual interviews per participant, collective interviews and focus groups. A total of 83 participants participated in the present study. Our analysis included 32 individual interviews (with 16 participants), 13 collective interviews (n = 45) and 8 focus groups (n = 33). We investigated adherence to on-demand pill-intake schedule, focusing especially on PrEP integration into daily life. PrEP intake was regulated through coping strategies to simplify implementation and avoid stigmatizing reactions. We considered self-care and pharmaceuticalization of prevention as specific features of sexual activity-based PrEP. As PrEP is a prophylaxis for seronegative people, it is contributing to the emergence of a new identity in the HIV field. Health-care professionals should take into account the practical implementation of PrEP schedules into daily life, assist PrEP users in personal management of pill intake and, more generally, improve adherence to the prophylaxis.

A multi-component, family-focused and literacy-sensitive intervention to improve medication adherence in patients with heart failure-A randomized controlled trial

BACKGROUND

Medication nonadherence is prevalent and links to serious outcomes (e.g., rehospitalization/death) in heart failure (HF) patients; therefore, an urgent need exists for an intervention to improve and sustain adherence after intervention completion.

OBJECTIVES

To test the efficacy of a multi-component, family-focused, literacy-sensitive (FamLit) intervention on medication adherence in HF patients.

METHODS

Forty-three HF patients and their care partners were enrolled and randomized to receive FamLit or attention-only intervention, including an in-person session at baseline and bi-weekly phone boosters for 3 months. We measured medication adherence from baseline to 3-month post-intervention using the Medication Event Monitoring System.

RESULTS

After 3-month intervention, intervention patients had significantly better medication adherence than control patients. At 6 months (3-months post-intervention), intervention effect on adherence was sustained in the FamLit intervention group, while adherence decreased in the control group.

CONCLUSION

Incorporating care partner support and providing an easy-to-understand intervention to patients-care partners may improve/sustain adherence.

Systematic procedures to promote U.S. HIV medication adherence via Photovoice

Medication adherence is essential to promote the health of people living with HIV (PL-HIV) and prevent HIV transmission in the U.S. Novel medication health promotion interventions are needed that address patient-centeredness, understandability, and communication with providers. The aims of this article are to define the systematic stages we used to develop an effective health promotion intervention via the products (e.g. images and stories) of Photovoice. We designed an intervention to improve HIV adherence knowledge, attitudes, and communication with providers through Photovoice. 16 PL-HIV used Photovoice strategies to describe their experiences with medication via images and captions and create an intervention (10 adherence promotion posters) that integrated photo-stories of their adherence motivators, journeys from sickness to health, and how they manage and counter HIV stigma. We outline the systematic process we used to adapt Photovoice to create the effective intervention for replication. The process included six stages: (i) identify scope of the project; (ii) create collaborative project team; (iii) design project materials; (iv) review and revise materials with team members; (v) disseminate materials; and (vi) evaluate materials. Photovoice is used traditionally as a social action research method. In this project, it was adapted to create patient-driven images and stories for health promotion posters. Poster viewers experienced improved self-efficacy for HIV medication adherence. Describing the adaptation of the Photovoice process in a deliberate and transparent way can support fidelity to the essence of the participant-driven method, while also allowing researchers and practitioners to replicate Photovoice as a successful health promotion intervention.

Acceptability, Feasibility, and Preliminary Efficacy of a Theory-Based Relational Embodied Conversational Agent Mobile Phone Intervention to Promote HIV Medication Adherence in Young HIV-Positive African American MSM

An embodied conversational agent can serve as a relational agent and provide information, motivation, and behavioral skills. To evaluate the feasibility, acceptability, and preliminary efficacy of My Personal Health Guide, a theory-based mobile-delivered embodied conversational agent intervention to improve adherence to antiretroviral therapy in young African American men who have sex with men, we conducted this prospective pilot study using a 3-month pre-post design. Outcome measures included adherence, acceptability, feasibility, pre versus post health literacy, and pre versus post self-efficacy. There were 43 participants. Pill count adherence > 80% improved from 62% at baseline to 88% at follow-up (p = .05). The acceptability of the app was high. Feasibility issues identified included loss of usage data from unplanned participant app deletion. Health literacy improved whereas self-efficacy was high at baseline and follow-up. This pilot study of My Personal Health Guide demonstrated acceptability and preliminary efficacy in improving adherence in this important population.

What if I cannot choose wisely? Addressing suboptimal health literacy in our patients to reduce over-diagnosis and overtreatment

The Choosing Wisely initiative aims to reduce wasteful and harmful healthcare by encouraging clinicians and patients to discuss explicitly the healthcare that is really needed as well as that which is of low or no value. While low health literacy has been found to be associated with under-diagnosis and under-treatment, its potential role as a driver of over-diagnosis and overtreatment has received less attention. This article describes how low health literacy might lead to too much medicine. It then provides an overview of an evidence-based method of communication that might assist with identifying and addressing low health literacy in patients.

Association Between Health Literacy, eHealth Literacy, and Health Outcomes Among Patients With Long-Term Conditions

Abstract. The objective of this paper is to synthesize and update findings from systematic review on health literacy and health outcomes among patients with long-term conditions, and extend the review to the digital domain. Health outcomes include clinical outcomes, processes of care, and health service use. Data sources are the following: (1) studies which appeared in two previous systematic reviews in 2004 and 2011 whose participants were people with long-term conditions or elderly ( n = 54); (2) articles on health literacy and health outcomes identified in an updated 2011–2016 search ( n = 26); (3) articles on eHealth literacy and its association with health outcomes ( n = 8). Strength of evidence was determined by a qualitative assessment of risk of bias, consistency, and directness. There was a lack of consistent evidence on the relationship between health literacy and clinical outcomes despite the consistent evidence on the association with mortality. There was low to insufficient evidence on the association between health literacy and self-rated health/function and emotional states of anxiety and depression, alongside high evidence on lack of association with quality of life. There was insufficient to low evidence on the association between health literacy and behavioral outcomes (medication adherence, other health behaviors) and finally also low to moderate evidence on the association between health literacy and use of health services such as hospitalization and emergency department. In the eHealth literacy domain, there were few studies reporting association with health behaviors and self-rated health with inconsistent results. In conclusion, it is advocated to examine performed heath literacy and eHealth literacy in large longitudinal studies.

Parental health literacy and progression of chronic kidney disease in children

BACKGROUND

Limited health literacy has been associated with adverse outcomes in children. We evaluated this association in the setting of chronic kidney disease (CKD).

METHODS

We assessed the parental health literacy of 367 children enrolled in the Chronic Kidney Disease in Children (CKiD) Study, using the Short Test of Functional Health Literacy (STOFHLA). We evaluated the association between parental health literacy and CKD progression, defined as time to the composite event of renal replacement therapy (RRT, dialysis, or kidney transplant) or 50% decline in estimated glomerular filtration rate (eGFR).

RESULTS

Median CKiD participant age was 9.5 years, 63% were male, and 59% non-Hispanic white. Median eGFR at baseline was 63 ml/min/1.73 m², and median urine protein-to-creatinine ratio was 0.22. The median STOFHLA score was 98. Over a median follow-up of 3.7 years, the overall CKD progression rate was 2.8 per 100 person-years. After adjustment for demographic and clinical factors, the relative time to CKD progression was 28% longer per 1 SD increase in STOFHLA score (relative time, 95% CI, 1.28, 1.06-1.53).

CONCLUSIONS

In this cohort of children with CKD, higher parental health literacy was associated with a nearly 30% longer time to the composite CKD progression outcome.

Health Literacy and Demographic Disparities in HIV Care Continuum Outcomes

Studies evaluating the association between human immunodeficiency virus (HIV) infection continuum of care outcomes [antiretroviral (ART) adherence, retention in care, viral suppression] and health literacy have yielded conflicting results. Moreover, studies from the southern United States, a region of the country disproportionately affected by the HIV epidemic and low health literacy, are lacking. We conducted an observational cohort study among 575 people living with HIV (PLWH) at the Vanderbilt Comprehensive Care Clinic (Nashville, Tennessee). Health literacy was measured using the brief health literacy screen, a short tool which can be administered verbally by trained clinical personnel. Low health literacy was associated with a lack of viral suppression, but not with poor ART adherence or poor retention. Age and racial disparities in continuum of care outcomes persisted after accounting for health literacy, suggesting that factors in addition to health literacy must be addressed in order to improve outcomes for PLWH.

A Realistic Talking Human Embodied Agent Mobile Phone Intervention to Promote HIV Medication Adherence and Retention in Care in Young HIV-Positive African American Men Who Have Sex With Men: Qualitative Study

Background

Avatars and embodied agents are a promising innovation for human health intervention because they may serve as a relational agent that might augment user engagement in a behavioral change intervention and motivate behavioral change such as antiretroviral adherence and retention in care.

Objective

This study aimed to develop a theory-driven talking avatar-like embodied agent mobile phone intervention guided by the information-motivation-behavioral skills model to promote HIV medication adherence and retention in care in young African American men who have sex with men (MSM).

Methods

We performed 5 iterative focus groups in Chicago with HIV-positive African American MSM aged 18-34 years to inform the ongoing development of a mobile phone app. Participants for the focus groups were recruited from 4 University of Illinois at Chicago Community Outreach Intervention Project sites located in different high HIV incidence areas of the city and the University of Illinois at Chicago HIV clinic using fliers and word of mouth. The focus group data analysis included developing an ongoing list of priorities for app changes and discussion between two of the investigators based on the project timeline, resources, and to what extent they served the app’s objectives.

Results

In this study, 16 men participated, including 3 who participated in two groups. The acceptability for an embodied agent app was universal in all 5 focus groups. The app included the embodied agent response to questions and antiretroviral regimen information, adherence tracking, CD4 count and viral load tracking, motivational spoken messages, and customizability. Concerns that were identified and responded to in the development process included privacy, stigma, avoiding the harsh or commanding tone of voice, avoiding negative motivational statements, and making reminder functions for a variety of health care interactions.

Conclusions

An avatar-like embodied agent mHealth approach was acceptable to young HIV-positive African American MSM. Its relational nature may make it an effective method of informing, motivating, and promoting health behavioral skills. Furthermore, the app’s ease of access, stigma-free environment, and audiovisual format may help overcome some adherence barriers reported in this population.

Experiences of HIV-positive postpartum women and health workers involved with community-based antiretroviral therapy adherence clubs in Cape Town, South Africa

Background

The rollout of universal, lifelong treatment for all HIV-positive pregnant and breastfeeding women (“Option B+”) has rapidly increased the number of women initiating antiretroviral treatment (ART) and requiring ART care postpartum. In a pilot project in South Africa, eligible postpartum women were offered the choice of referral to the standard of care, a local primary health care clinic, or a community-based model of differentiated ART services, the adherence club (AC). ACs have typically enrolled only non-pregnant and non-postpartum adults; postpartum women had not previously been referred directly from antenatal care. There is little evidence regarding postpartum women’s preferences for and experiences of differentiated models of care, or the capacity of this particular model to cater to their specific needs. This qualitative paper reports on feedback from both postpartum women and health workers who care for them on their respective experiences of the AC.

Methods

One-on-one in-depth qualitative interviews were conducted with 19 (23%) of the 84 postpartum women who selected the AC and were retained at approximately 12 months postpartum, and 9 health workers who staff the AC. Data were transcribed and thematically analysed using NVivo 11.

Results

Postpartum women’s inclusion in the AC was acceptable for both participants and health workers. Health workers were welcoming of postpartum women but expressed concerns about prospects for longer term adherence and retention, and raised logistical issues they felt might compromise trust with AC members in general.

Conclusions

Enrolling postpartum women in mixed groups with the general adult population is feasible and acceptable. Preliminary recommendations are offered and may assist in supporting the specific needs of postpartum women transitioning from antenatal ART care.

Self-efficacy and ability to read as factors associated with antiretroviral therapy adherence in an HIV-infected population

Determining the barriers and facilitators of antiretroviral adherence among former and current substance users may be useful in the creation of successful interventions that target this hard-to-reach population. We performed a cross-sectional study of HIV-infected patients (N = 123) prescribed antiretroviral therapy at four Chicago healthcare venues. Bivariate and multivariable analyses were performed to determine factors associated with non-adherence based on definitions of non-adherence (any missed doses) within the past 4-day, 14-day, and 1-month time periods. Factors consistently associated with non-adherence in bivariate and multivariate analyses, regardless of duration of non-adherence definition, were lower confidence in taking medication consistently and less self-reported ability to read. These data reveal the importance of self-efficacy and ability to read (rather than specific knowledge of CD4 and viral load definitions) in the design of interventions in a population of HIV-infected persons with significant substance use.

Acculturation and chronic kidney disease in the Hispanic community health study/study of Latinos (HCHS/SOL)

Hispanics/Latinos are burdened by chronic kidney disease (CKD). The role of acculturation in this population has not been explored. We studied the association of acculturation with CKD and cardiovascular risk factor control. We performed cross-sectional analyses of 13,164 U.S. Hispanics/Latinos enrolled in the HCHS/SOL Study between 2008 and 2011. Acculturation was measured using the language and ethnic social relations subscales of the Short Acculturation Scale for Hispanics, and proxies of acculturation (language preference, place of birth and duration of residence in U.S.). CKD was defined as estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m² or urine albumin-to-creatinine ratio ≥ 30 mg/g. On multivariable analyses stratified by age, lower language subscale score was associated with higher odds of CKD among those older than 65 (OR 1.29, 95% CI, 1.03, 1.63). No significant association was found between proxies of acculturation and CKD in this age strata. Among individuals aged 18–44, a lower language subscale score was associated with lower eGFR (β = −0.77 ml/min/1.73 m², 95% CI −1.43, −0.10 per 1 SD increase) and a similar pattern was observed for ethnic social relations. Among those older than 65, lower language subscale score was associated with higher log-albuminuria (β = 0.12, 95% CI 0.03, 0.22). Among individuals with CKD, acculturation measures were not associated with control of cardiovascular risk factors. In conclusion, lower language acculturation was associated with a higher prevalence of CKD in individuals older than 65. These findings suggest that older individuals with lower language acculturation represent a high risk group for CKD.

•

Among Hispanics/Latinos, lower language acculturation was associated with a higher prevalence of chronic kidney disease in older individuals.

•

Based on our findings, older individuals with lower language acculturation represent a high-risk group for chronic kidney disease.

Regular Marijuana Use is Associated with Poor Viral Suppression in HIV-Infected Adolescents and Young Adults

There is a paucity of data regarding the impact of drug use on HIV suppression and care retention among adolescents and young adults (AYAs). We recruited a clinic-based sample of HIV infected AYAs to assess the prevalence of self-reported drug use. Clinical data, including retention and viral suppression, were abstracted from the electronic medical record. Logistic regression was used to evaluate marijuana and illicit drug use associations and to identify other risk factors. Of 200 participants (mean age 21, 2.4 years, 69% horizontally infected), 46% reported current drug use, with marijuana as the most commonly used drug. Any illicit drug use (aOR 1.99, 95% CI 1.06-3.73, p = 0.032) and lower education (aOR 2.11, 95% CI 1.09-4.08, p = 0.046) were associated with poor viral suppression in multivariable analyses. Considering marijuana use only, an association with poor viral suppression was more pronounced (aOR 2.10, 95% CI 1.12-3.94, p = 0.021). Drug use did not have a significant association with retention in care, but AYAs who were retained in HIV care were less likely to have poorly suppressed HIV (aOR 0.22, 95% CI 0.10-0.49, p < 0.001). High prevalence of marijuana use among HIV infected AYAs, and its association with poorly suppressed HIV, demonstrates the need for intervention strategies to decrease its consumption.

The effect of a practice-based multicomponent intervention that includes health coaching on medication adherence and blood pressure control in rural primary care

Low adherence to anti-hypertensive medications contributes to worse outcomes. The authors conducted a secondary data analysis to examine the effects of a health-coaching intervention on medication adherence and blood pressure (BP), and to explore whether changes in medication adherence over time were associated with changes in BP longitudinally in 477 patients with hypertension. Data regarding medication adherence and BP were collected at baseline, 6, 12, 18, and 24 months. The intervention resulted in increases in medication adherence (5.75→5.94, P = .04) and decreases in diastolic BP (81.6→76.1 mm Hg, P < .001) over time. The changes in medication adherence were associated with reductions in diastolic BP longitudinally (P = .047). Patients with low medication adherence at baseline had significantly greater improvement in medication adherence and BP over time than those with high medication adherence. The intervention demonstrated improvements in medication adherence and diastolic BP and offers promise as a clinically applicable intervention in rural primary care.

Health literacy for people living with HIV/Aids: an integrative review

Objective:

to analyze knowledge produced by research about health literacy for adult with HIV/Aids.

Method:

an integrative literature review, using six databases, was conducted between January and April of 2014. The descriptors aids and Health Literacy were used, in Portuguese, English and Spanish. A total of 130 articles were found and 14 were selected. Three categories were identified: educational technologies and health literacy for HIV/Aids; assessment of health literacy of patients with HIV/Aids; and health literacy and adherence to antiretroviral therapy.

Results:

analysis of health literacy, socioeconomic status and educational level of people living with HIV/ Aids was essential for implementation of educational strategies that increased adherence to health guidance.

Conclusion:

this study showed the importance of health literacy for working with people living with HIV/Aids, especially considering individuals who did not possess the minimum necessary for survival, which makes it relevant and encourages further research on the topic.

Health Literacy Is an Independent Predictor of Cancer Patients' Hospitalizations

Background

Lower levels of health literacy predict higher hospitalization rates. Hospitalization is expensive and many admissions are potentially avoidable. Research examining the relationship between health literacy and health outcomes for cancer patients is limited, and no published studies to date have focused on hospitalization and health literacy in cancer patients.

Objective

This study examined the ability of health literacy to predict hospitalization of cancer patients.

Methods

This secondary data analysis investigated the relationship between health literacy and hospitalization rates of adult cancer patients in the first 5 years after their diagnosis. The sample included a diverse selection of cancer diagnoses and all stages of cancer were represented. Health literacy was assessed using the Cancer Health Literacy Test 30 (CHLT-30), a psychometrically sound measure of health literacy validated in a cancer patient population. Health literacy's ability to predict the number of times hospitalized, total days spent hospitalized, and number of 30-day readmissions was examined using multivariate negative binomial multiple regression to control for the outcomes and potentially confounding variables.

Key Results

When controlling for potentially confounding variables, a negative relationship was found between health literacy and the number of inpatient hospitalizations (β = -0.041, p = .009) and the total number of days spent hospitalized (β = -0.028, p = .023) independently, whereas the relationship between health literacy and the number of 30-day readmissions failed to reach significance (β = -0.002, p = .903).

Conclusions

Patients with lower health literacy need additional assistance to avoid unplanned hospitalizations. [Health Literacy Research and Practice. 2017;1(4):e153-e162.].

Plain Language Summary

Results from this study found that as cancer patients' health literacy scores decreased, the number of times hospitalized and the total number of days spent in the hospital increased. This relationship was significant when controlling for diagnosis, stage at diagnosis, receipt of chemotherapy, number of comorbidities, death, education, and race. Cancer patients with low health literacy are at a higher risk of being hospitalized.

Mediation effects of medication information processing and adherence on association between health literacy and quality of life

BACKGROUND

To examine whether medication related information processing defined as reading of over-the-counter drug labels, understanding prescription instructions, and information seeking-and medication adherence account for the association between health literacy and quality of life, and whether these associations may be moderated by age and gender.

METHODS

A sample of 305 adults in South Korea was recruited through a proportional quota sampling to take part in a cross-sectional survey on health literacy, medication-related information processing, medication adherence, and quality of life. Descriptive statistics and structural equation modeling (SEM) were performed.

RESULTS

Two mediation pathways linking health literacy with quality of life were found. First, health literacy was positively associated with reading drug labels, which was subsequently linked to medication adherence and quality of life. Second, health literacy was positively associated with accurate understanding of prescription instructions, which was associated with quality of life. Age moderation was found, as the mediation by reading drug labels was significant only among young adults whereas the mediation by understanding of medication instruction was only among older adults.

CONCLUSION

Reading drug labels and understanding prescription instructions explained the pathways by which health literacy affects medication adherence and quality of life. The results suggest that training skills for processing medication information can be effective to enhance the health of those with limited health literacy.

Do Persons Living with HIV Continue to Fill Prescriptions for Antiretroviral Drugs during a Gap in Care? Analysis of a Large Commercial Claims Database

The significance of a gap in HIV care depends, at least partially, on whether patients continue to fill prescriptions for antiretroviral (ARV) drugs during the gap in care. We used a billing claims database to determine the proportion of persons who filled ≥1 prescription for ARV drugs during a gap in care (no clinic visit in >6 months). Persons were stratified into 3 groups: "never" (prescriptions never filled), "sometimes" (prescriptions filled >0%-<100% of months), and "always" (prescriptions filled monthly). Logistic regression analyses were conducted to determine factors associated with "never" filling ARV drugs. Of 14 308 persons, 69% (n = 9817), 13% (n = 1928), and 18% (n = 2563) "never," "sometimes," and "always" filled ARV drugs during the gap in care. Persons aged 18 to 29 years (odds ratio [OR] = 1.56, 95% confidence interval [CI] 1.39-1.74), women (OR = 1.67, CI 1.52-1.83), and persons from the Northeast region of the United States (OR = 1.86, CI 1.69-2.03) were more likely to never fill ARV drugs than persons aged ≥30 years, men, and persons outside the Northeast, respectively. Efforts should be made to minimize gaps in care, emphasize importance of therapy, and provide adherence support.

Measuring Health Literacy Among Adults with HIV Infection in Mozambique: Development and Validation of the HIV Literacy Test

The role of health literacy on HIV outcomes has not been evaluated widely in Africa, in part because few appropriate literacy measures exist. We developed a 16-item scale, the HIV Literacy Test (HIV-LT) to assess literacy-related tasks needed to participate in HIV care. Items were scored as correct or incorrect; higher scores indicated higher literacy skill (range 0-100 %). We tested internal reliability (Kuder-Richardson coefficient) of the HIV-LT in a convenience sample of 319 Portuguese-speaking, HIV infected adults on antiretroviral treatment in Maputo, Mozambique. Construct validity was assessed by a hypothetical model developed a priori. The HIV-LT was reliable and valid to measure participants' literacy skills. The mean HIV-LT score was 42 %; literacy skills applicable to HIV care were challenging for many participants. The HIV-LT could be used to assess the relationship of literacy and HIV-related outcomes in diverse settings, and evaluate interventions to improve health communication for those in HIV care.

A Systematic Review of Health Literacy Interventions for People Living with HIV

Health literacy significantly impacts health-related outcomes among people living with HIV. Our aim was to systematically review current literature on health literacy interventions for people living with HIV. The authors conducted a thorough literature search following the PRISMA statement and the AMSTAR checklist as a guide, and found six studies that met inclusion/exclusion criteria. The majority of these interventions were designed to improve HIV treatment adherence as well as HIV knowledge and treatment-related skills, with one study focusing on e-Health literacy. Several of the studies demonstrated trends toward improvement in medication adherence, but most did not achieve statistical significance primarily due to methodological limitations. Significant improvements in knowledge, behavioral skills, and e-Health literacy were found following interventions (p = 0.001-0.05). Health literacy interventions have the potential to promote HIV-related knowledge, behavioral skills, and self-management practices. More research is needed to assess the efficacy of interventions to promote a variety of self-management practices.

Relationship of Health Literacy of Heart Failure Patients and Their Family Members on Heart Failure Knowledge and Self-Care

We explored the relationships among patients' and family members' (FMs) health literacy, heart failure (HF) knowledge, and self-care behaviors using baseline data from HF patients and their FMs ( N = 113 pairs) in a trial of a self-care intervention. Measures included Rapid Estimate of Adult Literacy in Medicine, Atlanta HF Knowledge Test, a heart failure Medication Adherence Scale, and sodium intake (24-hr urine and 3-day food record). Patients with low health literacy (LHL) were more likely to have lower HF knowledge ( p < .001) and trended to poorer medication adherence ( p = .077) and higher sodium intake ( p = .072). When FMs had LHL, FMs were more likely to have lower HF knowledge ( p = .001) and patients trended toward higher sodium intake ( p = .067). When both patients and FMs had LHL, lowest HF knowledge and poorest medication adherence were observed ( p < .027). The health literacy of both patient and FM needs to be considered when designing interventions to foster self-care.

Ethnicity, Stigma and Adherence to Antiretroviral Therapy (ART) among People Living with HIV/AIDS in Guangxi, China

This study examines the impact of ethnicity and multiple types of HIV-related stigma on adherence to antiretroviral therapy (ART) among 2,146 people living with HIV/AIDS (PLWHA) in Guangxi, China who had initiated ART. The results of multiple binary logistic regressions indicate that those who had experienced enacted stigma tended to report lower adherence, while better adherence was associated with older age, being women and having a job. Ethnicity had a moderator effect on the association between internalized stigma and adherence since better adherence was associated with lower internalized stigma among participants in ethnic minority groups other than Zhuang. Our findings indicate that PLWHA of other ethnic minority groups could benefit from internalized stigma reduction interventions; PLWHA, overall, could benefit most from increased employment opportunities and acquisition of coping skills to mitigate the negative effects of enacted stigma.
