Paradoxical effects of clinician emphasis on adherence to combination antiretroviral therapy for HIV/AIDS

Feasibility, Acceptability and Appropriateness of MedViewer: A Novel Hair-Based Antiretroviral Real-Time Clinical Monitoring Tool Providing Adherence Feedback to Patients and Their Providers

Antiretroviral therapy (ART) adherence is key to achieving viral load suppression and ending the HIV epidemic but monitoring and supporting adherence using current interventions is challenging. We assessed the feasibility, acceptability and appropriateness of MedViewer (MV), a novel intervention that provides real-time adherence feedback for patients and providers using infra-red matrix-assisted laser desorption electrospray ionization (IR-MALDESI) for mass spectrometry imaging of daily ART concentrations in patients' hair. We used mixed methods to feasibility test MV at a busy Infectious Diseases (ID) clinic, enrolling 16 providers and 36 patients. Providers underwent standardized training; patients and providers watched an 8-min informational video about MV. We collected patient and provider data at baseline and within 24 h of clinic visits and, with patients, approximately 1 month after clinic visits. MedViewer was feasible, liked by patients and providers, and perceived to help facilitate adherence conversations and motivate patients to improve adherence. Trial Registration: NCT04232540.

Experiences of HIV-infected adults and healthcare providers with healthcare delivery practices that influence engagement in US primary healthcare settings: a qualitative systematic review

INTRODUCTION

The human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) is a major public health problem that has claimed the lives of more than 34 million people worldwide. The health of people living with HIV (PLWH) is optimized by ongoing engagement in HIV care, yet many people living with HIV either do not enter or fall out of care. Access to care and ongoing engagement in care for antiretroviral (ARV) medication adherence and psychoeducational support are critical to achieving the desired outcomes of reducing the risk of further HIV transmission and HIV related morbidity and mortality, and managing other commonly co-occurring health, social and behavioral conditions, thereby maximizing wellness.

OBJECTIVE

The objective of the review was to identify, evaluate and synthesize existing qualitative evidence on the experiences of HIV-infected adults with healthcare systems/practices/processes, and the experiences of healthcare providers with healthcare systems/practices/processes that impact engagement in primary healthcare settings in the United States (US).

INCLUSION CRITERIA

The review included studies reporting on the qualitative experiences of HIV-infected adults, aged 18-65 years, with healthcare systems, practices and processes and their healthcare providers (physicians, nurses and others providing care to these patients in the primary care healthcare setting). Qualitative studies including but not limited to designs such as phenomenology, ethnography, grounded theory, action research and qualitative descriptive were included. Studies published in languages other than English and conducted outside of the US were excluded.

METHODS

Using a three-step search strategy, databases of published and unpublished articles were searched from 1997 to 2017. All included studies were assessed by two independent reviewers for methodological quality, and data was extracted and pooled using the Joanna Briggs Institute System for the Unified Management, Assessment and Review of Information (JBI SUMARI). Findings were rated according to their level of credibility, categorized based on similarity in meaning and subjected to a meta-synthesis.

RESULTS

A total of 1038 qualitative articles were identified of which 41 were included after critical appraisal. Meta-synthesis generated four synthesized findings: i) What I want from my provider: to be a respectful, empathetic and holistic partner in my care; ii) I cannot do it alone: the critical importance of actively guiding and assisting patients during transitions and securing the needed resources; iii) Help me to understand my illness and care needs; iv) One-stop care that is de-stigmatizing and welcoming to diverse cultures keeps clients in care. These synthesized findings were derived from 243 study findings that were subsequently aggregated into 19 categories. Of the 243 study findings, 240 were rated unequivocal and three were rated credible. The overall ConQual for each of the four synthesized findings was moderate due to common dependability issues across the included studies. A total of 1597 participants were included. Only two studies were included from 1997 to 2000. The majority of included studies were published from 2005 to 2017.

CONCLUSIONS

The synthesized findings illustrate clear quality indicators for primary care practice, emphasizing the patient-provider-care team partnership and shared decision making that is holistic, takes into account a patient's whole life, responsibilities and stressors, and reframes HIV associated misperceptions/myths. The review also highlights the importance of helping patients navigate and interact with the healthcare system by offering one-stop services that assist with multiple medical care needs and "wraparound" services that provide the needed care coordination to assist with critical quality of life needs such as food, housing, transportation, and assistance with applying for health insurance and medication.

Comorbid mental health disorders in persons living with HIV: Adherence to antiretroviral therapy

This is a secondary data analysis exploring adherence to antiretroviral therapy (ART) in persons living with HIV (PLWH) with a comorbid mental health disorder. Logistic regression analyses indicated that PLWH who had reliable housing were over six times more adherent than those with unreliable housing. Descriptive odds ratio analyses showed directional relationships for ART adherence with coping, employment, and social support. These results indicate areas for future investigation in PLWH and comorbid mental health disorders, and the potential to find ways to foster certain emotional or living conditions that promote ART adherence.

Doing patient-centredness versus achieving public health targets: A critical review of interactional dilemmas in ART adherence support

Anti-retroviral Therapy (ART) transformed HIV into a chronic disease but its individual and public health benefits depend on high levels of adherence. The large and rising number of people on ART, now also used as prevention, puts considerable strain on health systems and providers in low and middle as well as high-income countries, which are our focus here. Delivering effective adherence support is thus crucial but challenging, especially given the promotion of patient-centredness and shared decision making in HIV care. To illuminate the complexities of ART adherence support delivered in and through clinical encounters, we conducted a multi-disciplinary interpretative literature review. We reviewed and synthesized 82 papers published post 1997 (when ART was introduced) belonging to three bodies of literature: public health and psychological studies of ART communication; anthropological and sociological studies of ART; and conversation analytic studies of patient-centredness and shared decision-making. We propose three inter-related tensions which make patient-centredness particularly complex in this infectious disease context: achieving trust versus probing about adherence; patient-centredness versus reaching public health targets; and empowerment versus responsibilisation as 'therapeutic citizens'. However, there is a dearth of evidence concerning how precisely ART providers implement patient-centredness, shared-decision making in practice, and enact trust and therapeutic citizenship. We show how conversation analysis could lead to new, actionable insights in this respect.

Effects of Minimal Versus Intensive Intervention to Enhance Motivational Interviewing in HIV Care

We conducted a randomized trial comparing the effect of two different levels of motivational interviewing training on clinician communication behaviors and patient experiences. We enrolled 12 HIV clinicians who attended a one-day MI workshop focusing on behavior change counseling skills. We then randomized clinicians to receive (or not) 3-5 rounds of personalized feedback from the MI trainer. We compared outcomes before and after the interventions and between the intervention groups. We tested time-by-study arm interactions to determine if one group improved more than the other. For all analyses, we used generalized estimating equations to account for clustering of patients within clinicians, with Gaussian or negative binomial distributions as appropriate. Patients of clinicians in both intervention groups rated their visits as more MI consistent (6.86 vs. 6.65, p = 0.005) and audio-recording analysis revealed that visits were more patient-centered (1.34 vs. 0.96, p = 0.003) with a more positive patient affect (22.36 vs. 20.84, p < 0.001) after versus before the intervention, without differences between intervention arms. Several specific clinician behaviors such as empathic statements, asking patient opinions and open-ended questions improved more in the workshop+feedback versus the workshop-only intervention arm. A few specific communication behaviors increased (total and complex reflections) after versus before the intervention, without differences between intervention arms. The workshop alone was as effective as the workshop plus feedback in improving patient experiences and overall communication measures. Certain communication behaviors improved more with the more intensive intervention, but these additional benefits may not warrant the extra financial and logistical resources required.

Using the multiphase optimization strategy (MOST) to optimize an HIV care continuum intervention for vulnerable populations: a study protocol

BACKGROUND

More than half of persons living with HIV (PLWH) in the United States are insufficiently engaged in HIV primary care and not taking antiretroviral therapy (ART), mainly African Americans/Blacks and Hispanics. In the proposed project, a potent and innovative research methodology, the multiphase optimization strategy (MOST), will be employed to develop a highly efficacious, efficient, scalable, and cost-effective intervention to increase engagement along the HIV care continuum. Whereas randomized controlled trials are valuable for evaluating the efficacy of multi-component interventions as a package, they are not designed to evaluate which specific components contribute to efficacy. MOST, a pioneering, engineering-inspired framework, addresses this problem through highly efficient randomized experimentation to assess the performance of individual intervention components and their interactions. We propose to use MOST to engineer an intervention to increase engagement along the HIV care continuum for African American/Black and Hispanic PLWH not well engaged in care and not taking ART. Further, the intervention will be optimized for cost-effectiveness. A similar set of multi-level factors impede both HIV care and ART initiation for African American/Black and Hispanic PLWH, primary among them individual- (e.g., substance use, distrust, fear), social- (e.g., stigma), and structural-level barriers (e.g., difficulties accessing ancillary services). Guided by a multi-level social cognitive theory, and using the motivational interviewing approach, the study will evaluate five distinct culturally based intervention components (i.e., counseling sessions, pre-adherence preparation, support groups, peer mentorship, and patient navigation), each designed to address a specific barrier to HIV care and ART initiation. These components are well-grounded in the empirical literature and were found acceptable, feasible, and promising with respect to efficacy in a preliminary study.

METHODS/DESIGN

Study aims are: 1) using a highly efficient fractional factorial experimental design, identify which of five intervention components contribute meaningfully to improvement in HIV viral suppression, and secondary outcomes of ART adherence and engagement in HIV primary care; 2) identify mediators and moderators of intervention component efficacy; and 3) using a mathematical modeling approach, build the most cost-effective and efficient intervention package from the efficacious components. A heterogeneous sample of African American/Black and Hispanic PLWH (with respect to age, substance use, and sexual minority status) will be recruited with a proven hybrid sampling method using targeted sampling in community settings and peer recruitment (N = 512).

DISCUSSION

This is the first study to apply the MOST framework in the field of HIV prevention and treatment. This innovative study will produce a culturally based HIV care continuum intervention for the nation's most vulnerable PLWH, optimized for cost-effectiveness, and with exceptional levels of efficacy, efficiency, and scalability.

Factors influencing oral adherence: qualitative metasummary and triangulation with quantitative evidence

BACKGROUND

Concern about adherence to oral agents among patients with cancer has grown as more oral agents are being used for cancer treatment. Knowledge of common factors that facilitate or inhibit adherence to oral medication regimens can be beneficial to clinicians in identifying patients at risk for nonadherence, in planning care to address barriers to adherence, and in educating patients about ways to improve adherence.

OBJECTIVES

The focus of this review is to synthesize the evidence about factors that influence adherence and identify implications for practice.

METHODS

Literature was searched via PubMed and CINAHL®. Evidence regarding factors influencing adherence was synthesized using a metasummary of qualitative research and triangulated with findings from quantitative research.

FINDINGS

Forty-four factors influencing adherence were identified from 159 research studies of patients with and without cancer. Factors associated with adherence in oncology and non-oncology cases included provider relations, side effects, forgetfulness, beliefs about medication necessity, establishing routines for taking medication, social support, ability to fit medications in lifestyle, cost, and medication knowledge. Among patients with cancer, depression and negative expectations of results also were shown to have a negative relationship to adherence.

Which Clinician Questions Elicit Accurate Disclosure of Antiretroviral Non-adherence When Talking to Patients?

This study evaluated how clinicians assess antiretroviral (ARV) adherence in clinical encounters, and which questions elicit accurate responses. We conducted conversation analysis of audio-recorded encounters between 34 providers and 58 patients reporting ARV non-adherence in post-encounter interviews. Among 42 visits where adherence status was unknown by providers, 4 providers did not discuss ARVs (10 %), 6 discussed ARVs but did not elicit non-adherence disclosure (14 %), and 32 discussed ARVs which prompted disclosure (76 %). Questions were classified as: (1) clarification of medication ("Are you still taking the Combivir?"); (2) broad ("How's it going with your meds?"); (3) positively-framed ("Are you taking your medications regularly?"); (4) negatively-framed ("Have you missed any doses?"). Clinicians asked 75 ARV-related questions: 23 clarification, 12 broad, 17 positively-framed, and 23 negatively-framed. Negatively-framed questions were 3.8 times more likely to elicit accurate disclosure than all other question types (p < 0.0001). Providers can improve disclosure probability by asking directly about missed doses.

Behavioral intervention improves treatment outcomes among HIV-infected individuals who have delayed, declined, or discontinued antiretroviral therapy: a randomized controlled trial of a novel intervention

Nationally up to 60 % of persons living with HIV are neither taking antiretroviral therapy (ART) nor well engaged in HIV care, mainly racial/ethnic minorities. This study examined a new culturally targeted multi-component intervention to address emotional, attitudinal, and social/structural barriers to ART initiation and HIV care. Participants (N = 95) were African American/Black and Latino adults with CD4 < 500 cells/mm(3) not taking ART, randomized 1:1 to intervention or control arms, the latter receiving treatment as usual. Primary endpoints were adherence, evaluated via ART concentrations in hair samples, and HIV viral load suppression. The intervention was feasible and acceptable. Eight months post-baseline, intervention participants tended to be more likely to evidence "good" (that is, 7 days/week) adherence (60 vs. 26.7 %; p = 0.087; OR = 3.95), and had lower viral load levels than controls (t(22) = 2.29, p = 0.032; OR = 5.20), both large effect sizes. This highly promising intervention merits further study.

Patterns of disclosure and antiretroviral treatment adherence in a South African mining workplace programme and implications for HIV prevention

Social and psychological barriers to the disclosure of one's seropositive HIV status to significant others and poor adherence to taking medications pose significant challenges to the scaling-up of access to antiretroviral treatment (ART) in the workplace. Such barriers are predictive of sub-optimal treatment outcomes and bedevil HIV-prevention interventions at a societal level. Against this background, this article explores the lived experiences of 19 HIV-positive male participants, between the ages of 33 and 57 years, who were enrolled in an ART programme managed at an occupational health clinic at a mining company in South Africa. The majority of these mineworkers had been aware of their HIV status for between 5 and 7 years. The study explored psychological and relational factors, as aspects of these participants lived experiences, which had a bearing on their adherence to their ART regimen and the disclosure choices that they made regarding their HIV status. In our sample, those participants who were adherent demonstrated higher levels of control and acceptance of their HIV infection and were more confident in their ability to manage their treatment, while the group who were non-adherent presented with lower levels of adherence motivation and self-efficacy, difficulties in maintaining a healthy lifestyle and significant challenges in maintaining control over their lives. While most of the men favoured disclosing their HIV status to their partners for the sake of treatment support, they were less sure about disclosing to family members and non-family members, respectively, because of their need to protect these persons and due to their fear of being stigmatised. It was evident that treatment adherence choices and behaviours were impacted by psychological and relational factors, including disclosure decisions. We conclude with a bivariate model for understanding the adherence behaviours that influenced different patterns of ART adherence among the sample, and offer recommendations for HIV-prevention and treatment interventions in a mining workplace.

Impact of a brief patient and provider intervention to improve the quality of communication about medication adherence among HIV patients

INTRODUCTION

Medication adherence is essential in HIV care, yet provider communication about adherence is often suboptimal. We designed this study to improve patient-provider communication about HIV medication adherence.

METHODS

We randomized 26 providers at three HIV care sites to receive or not receive a one-hour communication skills training based on motivational interviewing principles applied to medication adherence. Prior to routine office visits, non-adherent patients of providers who received the training were coached to discuss adherence with their providers. Patients of providers who did not receive the training providers were not coached. We audio-recorded and coded patient-provider interactions using the roter interaction analysis system (RIAS).

RESULTS

There was more dialogue about therapeutic regimen in visits with intervention patients and providers (167 vs 128, respectively, p=.004), with the majority of statements coming from providers. These visits also included more brainstorming solutions to nonadherence (41% vs. 22%, p=0.026). Intervention compared with control visit providers engaged in more positive talk (44 vs. 38 statements, p=0.039), emotional talk (26 vs. 18 statements, p<0.001), and probing of patient opinion (3 vs. 2 statements, p=0.009).

CONCLUSION

A brief provider training combined with patient coaching sessions, improved provider communication behaviors and increased dialogue regarding medication adherence.

Loss to follow-up in a cohort of HIV-infected patients in a regional referral outpatient clinic in Brazil

One of the main aspects related to non-adherence to combined antiretroviral therapy (cART) for patients infected with the Human Immunodeficiency Virus (HIV) refers to the abandonment of outpatient care. This study was aimed to estimate the loss to follow-up in outpatient HIV care at a Regional Referral Clinic (SAE) for HIV/AIDS in the city of Juiz de Fora, Brazil, and to identify associated factors and predictors. This is a prospective cohort of patients older than 18 years, under cART and regular outpatient care. The study included patients who attended medical visits during July-August 2011. Those who did not return to the clinic for new medical appointments within 90 days after the sixth month of follow up were considered lost to follow-up in outpatient care. Variables with P value ≤0.25 in the univariate analysis were included in a logistic regression model, adopting a significance level of 0.05. Among the 250 patients included in the study, 44 (17.6 %) were lost to follow up in outpatient care. Among these, 38 (86.4 %) were located in the cART delivery database system (SICLOM). Younger patients (≤43 versus >43 years) (OR 2.30 CI 1.06-5.00, P = 0.04), and patients attended by physician "E", when compared with physicians "A", "B", "C" or "D" (OR 5.90 CI 2.64-13.18, P = 0.00) were more likely to be lost to follow-up. Patients admitted in the service for 7 years or more were also more likely to be to lost to follow-up (OR 2.27 CI 1.2-4.4, P = 0.01), although this association did not remain statistically significant in the multivariate analysis. Although the purpose of the study, to identify individual factors associated to loss to follow-up, positives associations with a specific physician and with patients admitted in the service for 7 years or more suggest organizational factors. Although the majority of patients lost to follow-up in outpatient care were detected by SICLOM, a detectable viral load in most of these patients suggest a quality of outpatient HIV care proved ineffective, despite the availability of cART. We conclude on the need for further studies to investigate structural factors associated to loss to follow-up when enhanced retention strategies should be implemented in order to maintain an effective outpatient HIV care.

Individual and contextual factors influencing patient attrition from antiretroviral therapy care in an urban community of Lusaka, Zambia

BACKGROUND

Despite the relatively effective roll-out of free life-prolonging antiretroviral therapy (ART) in public sector clinics in Zambia since 2005, and the proven efficacy of ART, some people living with HIV (PLHIV) are abandoning the treatment. Drawing on a wider ethnographic study in a predominantly low-income, high-density residential area of Lusaka, this paper reports the reasons why PLHIV opted to discontinue their HIV treatment.

METHODS

Opened-ended, in-depth interviews were held with PLHIV who had stopped ART (n =25), ART clinic staff (n=5), religious leaders (n=5), herbal medicine providers (n=5) and lay home-based caregivers (n=5). In addition, participant observations were conducted in the study setting for 18 months. Interview data were analysed using open coding first, and then interpreted using latent content analysis. The presentation of the results is guided by a social-ecological framework.

FINDINGS

Patient attrition from ART care is influenced by an interplay of personal, social, health system and structural-level factors. While improved corporeal health, side effects and need for normalcy diminished motivation to continue with treatment, individuals also weighed the social and economic costs of continued uptake of treatment. Long waiting times for medical care and placing "defaulters" on intensive adherence counselling in the context of insecure labour conditions and livelihood constraints not only imposed opportunity costs which patients were not willing to forego, but also forced individuals to balance physical health with social integrity, which sometimes forced them to opt for faith healing and traditional medicine.

CONCLUSIONS

Complex and dynamic interplay of personal, social, health system and structural-level factors coalesces to influence patient attrition from ART care. Consequently, while patient-centred interventions are required, efforts should be made to improve ART care by extending and establishing flexible ART clinic hours, improving patient-provider dialogue about treatment experiences and being mindful of the way intensive adherence counselling is being enforced. In the context of insecure labour conditions and fragile livelihoods, this would enable individuals to more easily balance time for treatment and their livelihoods. As a corollary, the perceived efficacy of alternative treatment and faith healing needs to be challenged through sensitizations targeting patients, religious leaders/faith healers and herbal medicine providers.

Challenges to physician-patient communication about medication use: a window into the skeptical patient's world

Patients frequently do not take medicines as prescribed and often do not communicate with their physicians about their medication-taking behavior. The movement for "patient-centered" care has led to relabeling of this problem from "noncompliance" to "nonadherence" and later to a rhetoric of "concordance" and "shared decision making" in which physicians and patients are viewed as partners who ideally come to agreement about appropriate treatment. We conducted a qualitative content analysis of online comments to a New York Times article on low rates of medication adherence. The online discussion provides data about how a highly selected, educated sample of patients thinks about medication use and the doctor-patient relationship. Our analysis revealed patient empowerment and self-reliance, considerable mistrust of medications and medical practice, and frequent noncommunication about medication adherence issues. We discuss how these observations can potentially be understood with reference to Habermas's theory of communicative action, and conclude that physicians can benefit from better understanding the negative ways in which some patients perceive physicians' prescribing practices.

"Only two months destroys everything": a case study of communication about nonadherence to antiretroviral therapy in a South African HIV pharmacy context

Adherence to antiretroviral treatment (ART) is a complex phenomenon and patients do not always adhere for a variety of reasons. The quality of communication and the therapeutic relationship between health professionals and patients have an important influence on adherence, as do contextual and environmental factors. Little qualitative research exists that examines health care interactions in the context of adherence counselling. This article presents a case study of a discussion about nonadherence between a pharmacy assistant and a patient in a South African HIV context. A hybrid analytical approach revealed various themes such as how the topic of nonadherence is addressed, participants' responses to the patient's nonadherence, and the process of negotiating a new commitment to adherence. The case provides insight into the impact of contextual factors on the interaction and challenges involved in discussing nonadherence-in particular, the patient's attempts to save face, the pharmacy assistant's irritation and anger, and the patient's expressed regrets. This case raises questions around issues of patient agency. Health professionals are encouraged to consider the influence of context, lifeworld, and culture on patients' ability to adhere to treatment regimens. By working to improve communication processes and strengthen the therapeutic relationship, patients may be empowered to achieve better adherence levels.

"Now here come the pills that are going to save your life": pharmacists' discussions of antiretroviral drugs in a context of life and death

HIV/AIDS has associated cultural and social meanings which shape communication. The disease is closely linked to the concepts of life and death. Antiretroviral therapy (ART) has brought hope and life, but its success is heavily dependent on strict adherence. Research has shown that patients and health professionals often find it difficult to talk about these topics. However, there is little research available which focuses on health professionals' and patients' discussion of ART. This paper thus presents some exploratory discussion of extracts from pharmacy interactions in an HIV context which illustrate how pharmacists talk about antiretrovirals (ARVs) with patients with particular reference to the concepts of life and death. Data are taken from 26 video pharmacist-patient interactions recorded in a South African HIV/AIDS pharmacy. A hybrid qualitative analytic approach enabled identification of three types of references to ART, including the need to take ART "for the rest of your life", ART as "saving your life" and ART as "making you better". Explicit references to death were infrequent. These references were often emphatic and there are several potential reasons for this. The pharmacists' communication appears to be influenced by the urgency of the disease, a desire to give patients hope and a need to "normalise" discussions of death and HIV. The importance of ensuring understanding of ARV dosage instructions and discouraging patients from seeking traditional healing also appears to affect communication. The disease, societal and cultural contexts are thus shown to be significant influences which shape discussions of ART. This study has a number of practical implications, which are discussed.

Maximizing health literacy and client recall in a developing context: speech-language therapist and client perspectives

BACKGROUND

In the field of speech-language therapy, limited research has been conducted with regards to health literacy and client recall. However, speech-language therapists frequently provide a considerable amount of information for clients to understand, apply and review in order to manage their (or their child's) health.

AIMS

This study aimed to investigate (1) issues around clients' health literacy and recall of information; and (2) how these issues can be overcome in speech-language therapy in a developing context.

METHOD & PROCEDURES

An exploratory study was undertaken with specific focus on speech-language therapists and their clients who had previously received treatment for dysphagia, voice disorders (including laryngectomies), and cleft lip and/or palate management. They were recruited at public tertiary hospitals and primary healthcare clinics in Cape Town, South Africa. Data were gathered through focus group discussions and qualitatively analysed using a content-driven immersion/crystallization style.

OUTCOMES & RESULTS

Five themes and 13 subthemes were identified. Speech-language therapists currently use mostly low-technology strategies to manage issues of health literacy and client recall, and frequently view poor outcomes as being related to clients themselves and a lack of compliance.

CONCLUSIONS & IMPLICATIONS

An understanding of context, intercultural health literacy and client-provider concordance are important factors that should inform the clinical practice of speech-language therapy. There is a need to develop effective strategies for information provision and review post-consultation. Speech-language therapists have an important mediating role in cross-cultural communication.

Why don't patients take their drugs? The role of communication, context and culture in patient adherence and the work of the pharmacist in HIV/AIDS

OBJECTIVE

This study examined facilitators and barriers to adherence in four South African antiretroviral therapy (ART) clinic sites and explored context and communication factors in relation to the role of the pharmacist.

METHODS

Data were collected from interviews and narratives of patients and health professionals around the issues of adherence and qualitatively analysed using principles of Thematic Content Analysis.

RESULTS

Findings confirm the complex interplay between illness, communication, sociocultural, economic, context and systemic issues. Analysis suggests adherence is multifaceted and reinforces the critical role of communication factors in achieving concordance between patient and pharmacist.

CONCLUSION

Successful treatment of HIV/AIDS depends on pharmacists and healthcare teams understanding contextual and interactional factors which play a role in adherence.

PRACTICE IMPLICATIONS

The findings reinforce the importance of embedding a patient-centred approach in the training and everyday practice of pharmacists. The value of qualitative methods in understanding barriers to adherence and the potential value of the cultural broker in intercultural settings is discussed. Some suggestions are made as to how adherence counselling can be made relevant and effective.

The Opinions of Injecting Drug User (IDUs) HIV Patients and Health Professionals on Access to Antiretroviral Treatment and Health Services in Valencia, Spain

The benefits of HIV treatment (Highly Active Antiretroviral Therapy [HAART]) have been less apparent in injecting drug users (IDUs), most probably as a result of poor adherence to treatment. We explored factors related to HIV treatment adherence as reported by 23 IDU-HIV patients and nine health professionals from healthcare services in Alicante and Valencia, Spain. We carried out a qualitative study based on personal interviews. Health professionals reported the lack of coordination among hospital services and difficulties in accessibility to nonspecialized services for IDU-HIV patients as relevant factors for treatment adherence. Their perception of a patient’s likelihood of treatment adherence was also considered to influence the decision to prescribe HAART. A better treatment adherence was reported by those IDU-HIV patients with a good doctor–patient relationship and by women with family responsibilities. Patients considered the side effects of HIV treatment, the lack of social support, and the active use of recreational drugs as relevant factors to explain incompliance. Interventions and training of health providers should be aimed at the reduction of barriers in patient–provider communication and the overcoming of stereotypes, thus avoiding discriminatory attitudes in treatment in this vulnerable population.

Provider-focused intervention increases adherence-related dialogue but does not improve antiretroviral therapy adherence in persons with HIV

BACKGROUND

Physicians' limited knowledge of patients' antiretroviral adherence may reduce their ability to perform effective adherence counseling.

METHODS

We conducted a randomized, cross-over study of an intervention to improve physicians' knowledge of patients' antiretroviral adherence. The intervention was a report given to the physician before a routine office visit that included data on Medication Event Monitoring System and self-reported data on antiretroviral adherence, patients' beliefs about antiretroviral therapy, reasons for missed doses, alcohol and drug use, and depression. We audio recorded 1 intervention and 1 control visit for each patient to analyze differences in adherence-related dialogue.

RESULTS

One hundred fifty-six patients were randomized, and 106 completed all 5 study visits. Paired audio recorded visits were available for 58 patients. Using a linear regression model that adjusted for site and baseline Medication Event Monitoring System adherence, adherence after intervention visits did not differ significantly from control visits (2.0% higher, P = 0.31, 95% confidence interval: -1.95% to 5.9%). There was a trend toward more total adherence-related utterances (median of 76 vs. 49.5, P = 0.07) and a significant increase in utterances about the current regimen (median of 51.5 vs. 32.5, P = 0.0002) in intervention compared with control visits. However, less than 10% of adherence-related utterances were classified as "problem solving" in content, and one third of physicians' problem-solving utterances were directive in nature.

CONCLUSIONS

Receipt of a detailed report before clinic visits containing data about adherence and other factors did not improve patients' antiretroviral adherence. Analyses of patient-provider dialogue suggests that providers who care for persons with HIV may benefit from training in adherence counseling techniques.

Factors influencing adherence to antiretroviral therapy for HIV-infected female inmates

New HIV cases are increasing among women, especially women of color. Moreover, the rate of infection for incarcerated women is twice that of incarcerated men. With advances in medication therapy, HIV has become a chronic illness that can be successfully treated, provided the patient is able to achieve adherence with the prescribed antiretroviral medication regimen. Incarcerated women, however, frequently come from environments burdened with violence, substance and physical abuse, homelessness, child-care issues, and mental illness. Such burdens negatively affect the ability of these women to adhere to the medication plan. This study explored incarcerated HIV-infected women's barriers to and facilitators of adherence to antiretroviral therapy (ART), the role of health care provider relationships in adherence, and the ways in which issues of medical privacy influence ability or desire to adhere while incarcerated. A secondary analysis of an existing set of qualitative interviews with HIV-infected female inmates was conducted.

Adherence to Antiretroviral Therapy in the Context of the National Roll-Out in South Africa: Defining a Research Agenda for Psychology

Since 2004, antiretroviral therapy (ART) has been provided by the South African Department of Health to patients who need it as part of the national ART roll-out. Despite the initial success of a trial ART programme in Khayelitsha near Cape Town, it is unclear that adherence to ART is optimal among the patients receiving treatment in the context of the national roll-out. In this article I call attention to the psychosocial barriers to adherence that may potentially be faced by patients receiving ART. These barriers include poverty, health literacy, perceived social support, mental health, substance abuse, and stigma. Three social cognitive theories are briefly reviewed to conceptualise the phenomenon of ART adherence, namely, the Health Belief Model, the Theory of Planned Behaviour, and the Informational—Behavioural—Motivational Model. Constructs such as health motivation, perceived threats, perceived barriers, attitudes towards ART, perceived subjective norms, and perceived behavioural control are examined for their potential role in developing a theoretical understanding of adherence to ART. Finally, the role of culture is considered in response to concerns that social cognitive models developed in industrially developed countries are limited in their application in a developing country such as South Africa. As the question of adherence to ART in South Africa has received little attention from social science researchers, I set a tentative agenda for psychosocial research with a view to enhancing the likelihood of optimal adherence among AIDS patients.

The provider role in client engagement in HIV care

This multisite, qualitative study examined the process by which persons living with HIV/AIDS (PLWHA) engage in primary HIV medical care for treatment. Using a grounded theory approach, the analysis of narrative data from semi-structured in-depth interviews with PLWHA (n = 76) led to the development of a model describing a cyclic process of engaging in--and falling out of--care. Perceptions of the client-provider relationship emerged as a central element of the process by which persons with HIV engaged--or remained--in care. Provider behaviors that were characterized as engaging, validating, and partnering facilitated engagement and retention in care; behaviors described as paternalistic served as barriers to care. Participants indicated that they desired a care partnership with an empathetic provider who had effective communication skills. These findings provide recommendations for health providers to engage and retain hard-to-reach PLWHA in timely and appropriate HIV care and services.

The Role of Adherence to Antiretroviral Therapy in the Management of HIV Infection

Despite multiple studies demonstrating the relation between the success of highly active antiretroviral therapy (HAART) and adherence, inadequate adherence continues to be one of the most frequent reasons for poor treatment outcomes and/or lack of sustained treatment benefits. Interventions targeting patient-related social and psychologic barriers to adherence and issues related to mental health and substance abuse and access to health care may ameliorate their negative impact on adherence. Specific drug-related factors that influence adherence such as pill burden, dosing frequency, food requirements, and acute tolerability and safety concerns, however, are further issues that must be considered to optimize adherence. Fortunately, the availability of once-daily and coformulated agents with simple dosing requirements may help to improve adherence, and thereby make the difference between success and failure of HAART for some patients. A better understanding of adherence and its determinants and how to define specific goals in a given clinical setting are keys for clinicians to become more effective partners with patients in the achievement and maintenance of long-term virologic suppression and, more importantly, long-term health.

How qualitative methods contribute to understanding combination antiretroviral therapy adherence

Strict adherence to medication regimens is generally required to obtain optimal response to combination antiretroviral therapy (ART). Yet, we have made limited progress in developing strategies to decrease the prevalence of nonadherence. As we work to understand adherence in developed countries, the introduction of ART in resource-poor settings raises novel challenges. Qualitative research is a scientific approach that uses methods such as observation, interviews, and verbal interactions to gather rich in-depth information about how something is experienced. It seeks to understand the beliefs, values, and processes underlying behavioral patterns. Qualitative methods provide powerful tools for understanding adherence. Culture-specific influences, medication beliefs, access, stigma, reasons for nonadherence, patterns of medication taking, and intervention fidelity and measurement development are areas ripe for qualitative inquiry. A disregard for the social and cultural context of adherence or the imposition of adherence models inconsistent with local values and practices is likely to produce irrelevant or ineffective interventions. Qualitative methods remain underused in adherence research. We review appropriate qualitative methods for and provide an overview of the qualitative research on ART nonadherence. We discuss the rationales for using qualitative methods, present 2 case examples illustrating their use, and discuss possible institutional barriers to their acceptance.
