HIV-infected women's decisions to take antiretrovirals

Does peer-navigated linkage to care work? A cross-sectional study of active linkage to care within an integrated non-communicable disease-HIV testing centre for adults in Soweto, South Africa

INTRODUCTION

South Africa is the HIV epidemic epicentre; however, non-communicable diseases (NCDs) will be the most common cause of death by 2030. To improve identification and initiation of care for HIV and NCDs, we assessed proportion of clients referred and linked to care (LTC) for abnormal/positive screening results and time to LTC and treatment initiation from a HIV Testing Services (HTS) Centre before and after integrated testing for NCDs with optional peer-navigated linkage to care.

MATERIALS AND METHODS

This two-phase prospective study was conducted at an adult HTS Centre in Soweto, South Africa. Phase 1 (February-June 2018) utilised standard of care (SOC) HTS services (blood pressure [BP], HIV rapid diagnostic testing (RDT), sexually transmitted infections [STI]/Tuberculosis [TB] symptom screening) with passive referral for abnormal/positive results. Phase 2 (June 2018-March 2019) further integrated blood glucose/cholesterol/chlamydia RDT, with optional peer-navigated referral. Enrolled referred clients completed telephonic follow-up surveys confirming LTC/treatment initiation ≤3 months post-screening. Socio-demographics, screening results, time to LTC/treatment initiation, peer-navigated referral uptake were reported. Analysis included Fisher's exact, chi-squared, Kruskal Wallis, and Student's T-tests. Thematic analysis was conducted for open-ended survey responses.

RESULTS

Of all 320 referrals, 40.0% were HIV-infections, 11.9% STIs, 6.6% TB, and 28.8% high/low BP. Of Phase 2-only referrals, 29.4% were for glucose and 23.5% cholesterol. Integrated NCD-HTS had significantly more clients LTC for HIV (76.7%[n = 66/86] vs 52.4%[n = 22/42], p = 0.0052) and within a shorter average time (6-8 days [Interquartile range (IQR):1-18.5] vs 8-13 days [IQR:2-32]) as compared to SOC HTS. Integrated NCD-HTS clients initiated HIV/STIs/BP treatment on average more quickly as compared to SOC HTS (5 days for STIs [IQR:1-21], 8 days for HIV/BP [IQR:5-17 and 2-13, respectively] vs 10 days for STIs [IQR: 4-32], 19.5 days for HIV [IQR:6.5-26.5], 8 days for BP [IQR:2-29)]. Participants chose passive over active referral (89.1% vs 10.9%; p<0.0001). Participants rejecting peer-navigated referral preferred to go alone (55.7% [n = 39/70]). Non-LTC was due to being busy (41.1% [n = 39/95]) and not being ready/refusing treatment (31.6% [n = 30/95]). Normalised results assessed at referral clinic (49.7% [n = 98/196]), prescribed lifestyle modification/monitoring (30.9% [n = 61/196]), and poor clinic flow/congestion and/or further testing required (10.7% [n = 21/196]) were associated with non-treatment initiation.

CONCLUSION

Same-day treatment initiation is not achieved across diseases, despite peer-navigated referral. There are psychosocial and health systems barriers at entry to care/treatment initiation. Additional research may identify best strategies for rapid treatment initiation.

Resilience resources among African American women living with HIV in Southern United States

OBJECTIVES

African American women living with HIV (WLH) often face various challenges to access to and benefit from healthcare across the HIV treatment cascade. Despite experiencing multiple forms of ongoing adversity, some African American WLH are able to adapt and stand strong. The current study aims to identify resources at various socioecological levels that facilitate resilience and explore how these resources interact with each other.

DESIGN

Guided by the theories of resilience, we collected qualitative data through in-depth interviews with 14 African American WLH in South Carolina, United States.

METHODS

Participants were purposely recruited and interviewed in private settings in 2016. With appropriate consent, each interview was recorded and was transcribed verbatim. Data analysis was conducted using NVivo 11.0.

RESULTS

The participants described six major resilience resources including first, internal strength; second, religion and spirituality; third, hopefulness about life and future; fourth, self-awareness and self-care; fifth, social support from family and community; and sixth, HIV-related health facilities. The themes that occurred in qualitative data also show how resilience resources at the family/community level and institutional level affected individual resources, and how these resources collaborated with each other.

CONCLUSION

The findings suggest that resilient African American WLH maintain hope in the face of adversity and seek out and obtain social support. Self-care, social support, and health facilities are particularly critical resources for African American WLH. Comprehensive interventions are needed to integrate these resources across multiple socioecological levels to enhance resilience and treatment outcomes in African American WLH.

Factors Supporting and Inhibiting Adherence to HIV Medication Regimen in Women: A Qualitative Analysis of Patient Interviews

Adherence to antiretroviral therapy reduces morbidity and mortality; however rates of non-adherence are variable among women for unclear reasons. This study was a single-center qualitative analysis of interviews with 18 female HIV-positive non-adherent patients (defined by virologic failure) to explore psychosocial factors impacting adherence. Factors identified were categorized as promoting, inhibiting or having no effect on adherence. Three themes, characterized as social factors, illness factors and other societal pressures, were identified. Medical systems support, family support and compliance for children were most commonly identified as promoting adherence, while psychiatric comorbidities, lack of medical systems support and side effects were identified most often as inhibitors of adherence. While stigma was frequently identified, it was not seen as a barrier to adherence. Enhancing relationships between patients and their providers as well as their community support systems are critical avenues to pursue in improving compliance. Interventions to promote compliance are important avenues of future research.

Assessing HIV and AIDS treatment safety and health-related quality of life among cohort of Malaysian patients: a discussion on methodological approach

BACKGROUND

Health-related quality of life (HRQoL) is increasingly recognized as an important outcome and as a complement to traditional biological end points of diseases such as mortality. Unless there is a complete cure available for HIV/AIDS, development and implementation of a reliable and valid cross cultural quality of life measure is necessary to assess not only the physical and medical needs of HIV/AIDS people, but their psychological, social, environmental, and spiritual areas of life.

METHODS

A qualitative exploration of HIV/AIDS patients' understanding, perceptions and expectations will be carried out with the help of semi structured interview guide by in depth interviews, while quantitative assessment of patient reported adverse drug reactions and their impact on health related quality of life will be carried out by using data collection tool comprising patient demographics, SF-12, Naranjo scale, and a clinical data sheet.

RESULTS/OUTCOMES

The findings may serve as baseline QOL data of people living with HIV/AIDS in Malaysia and also a source data to aid construction of management plan to improve HIV/AIDS patients' QOL. It will also provide basic information about HIV/AIDS patients' perceptions, expectations and believes towards HIV/AIDS and its treatment which may help in designing strategies to enhance patients' awareness which in turn can help in addressing issues related to compliance and adherence.

Current strategies for improving access and adherence to antiretroviral therapies in resource-limited settings

The rollout of antiretroviral therapy (ART) significantly reduced human immunodeficiency virus (HIV)-related morbidity and mortality, but good clinical outcomes depend on access and adherence to treatment. In resource-limited settings, where over 90% of the world's HIV-infected population resides, data on barriers to treatment are emerging that contribute to low rates of uptake in HIV testing, linkage to and retention in HIV care systems, and suboptimal adherence rates to therapy. A review of the literature reveals limited evidence to inform strategies to improve access and adherence with the majority of studies from sub-Saharan Africa. Data from observational studies and randomized controlled trials support home-based, mobile and antenatal care HIV testing, task-shifting from doctor-based to nurse-based and lower level provider care, and adherence support through education, counseling and mobile phone messaging services. Strategies with more limited evidence include targeted HIV testing for couples and family members of ART patients, decentralization of HIV care, including through home- and community-based ART programs, and adherence promotion through peer health workers, treatment supporters, and directly observed therapy. There is little evidence for improving access and adherence among vulnerable groups such as women, children and adolescents, and other high-risk populations and for addressing major barriers. Overall, studies are few in number and suffer from methodological issues. Recommendations for further research include health information technology, social-level factors like HIV stigma, and new research directions in cost-effectiveness, operations, and implementation. Findings from this review make a compelling case for more data to guide strategies to improve access and adherence to treatment in resource-limited settings.

'Dying from' to 'living with': framing institutions and the coping processes of African American women living with HIV/AIDS

How do HIV-positive individuals transition from believing and behaving as though they have a 'death sentence' to interpreting and coping with HIV as a chronic but manageable illness? Using interview data collected from 30 HIV-positive African American women beginning in 2005, we reveal how and why interactions with non-profit and government institutions help to explain variation between those who thrive and those who do not following an HIV diagnosis. We argue that 'framing institutions' shape the form and tenor of coping trajectories by offering initial information about one's HIV status, a conceptual framework for understanding what it means to have HIV, language to talk about one's condition, and resources to begin restructuring one's life in the wake of a diagnosis. Ultimately, we highlight how a diverse array of non-profit and government institutions not only play a critical part in helping women cope with HIV but also renegotiate their self-conceptions as black women in the wake of receiving another stigmatizing social marker. In short, organizational ties shape women's movement from beliefs and behaviors that suggest that they are 'dying from' this disease to attitudes and actions consistent with the notion that they can 'live with' HIV.

Bayesian data augmentation methods for the synthesis of qualitative and quantitative research findings

The possible utility of Bayesian methods for the synthesis of qualitative and quantitative research has been repeatedly suggested but insufficiently investigated. In this project, we developed and used a Bayesian method for synthesis, with the goal of identifying factors that influence adherence to HIV medication regimens. We investigated the effect of 10 factors on adherence. Recognizing that not all factors were examined in all studies, we considered standard methods for dealing with missing data and chose a Bayesian data augmentation method. We were able to summarize, rank, and compare the effects of each of the 10 factors on medication adherence. This is a promising methodological development in the synthesis of qualitative and quantitative research.

A systematic review comparing antiretroviral adherence descriptive and intervention studies conducted in the USA

We examined the extent to which studies aimed at testing interventions to improve antiretroviral adherence have targeted the facilitators of and barriers known to affect adherence. Of the 88 reports reviewed, 41 were reports of descriptive studies conducted with US HIV-positive women and 47 were reports of intervention studies conducted with US HIV-positive persons. We extracted from the descriptive studies all findings addressing any factor linked to antiretroviral adherence and from the intervention studies, information on the nature of the intervention, the adherence problem targeted, the persons targeted for the intervention, and the intervention outcomes desired. We discerned congruence between the prominence of substance abuse as a factor identified in the descriptive studies as a barrier to adherence and its prominence as the problem most addressed in those reports of intervention studies that specified the problems targeted for intervention. We also discerned congruence between the prominence of family and provider support as factors identified in the descriptive studies as facilitators of adherence and the presence of social support as an intervention component and outcome variable. Less discernible in the reports of intervention studies was specific attention to other factors prominent in the descriptive studies, which may be due to the complex nature of the problem, individualistic and rationalist slant of interventions, or simply the ways interventions were presented. Our review raises issues about niche standardization and intervention tailoring, targeting, and fidelity.

A Bayesian method for the synthesis of evidence from qualitative and quantitative reports: the example of antiretroviral medication adherence

OBJECTIVES

Bayesian meta-analysis is a frequently cited but very little-used method for synthesizing qualitative and quantitative research findings. The only example published to date used qualitative data to generate an informative prior probability and quantitative data to generate the likelihood. We developed a method to incorporate both qualitative and quantitative evidence in the likelihood in a Bayesian synthesis of evidence about the relationship between regimen complexity and medication adherence.

METHODS

Data were from 11 qualitative and six quantitative studies. We updated two different non-informative prior distributions with qualitative and quantitative findings to find the posterior distribution for the probabilities that a more complex regimen was associated with lower adherence and that a less complex regimen was associated with greater adherence.

RESULTS

The posterior mode for the qualitative findings regarding more complex regimen and lesser adherence (using the uniform prior with Jeffreys' prior yielding highly similar estimates) was 0.588 (95% credible set limits 0.519, 0.663) and for the quantitative findings was 0.224 (0.203, 0.245); due to non-overlapping credible sets, we did not combine them. The posterior mode for the qualitative findings regarding less complex regimen and greater adherence was 0.288 (0.214, 0.441) and for the quantitative findings was 0.272 (0.118, 0.437); the combined estimate was 0.299 (0.267, 0.334).

CONCLUSIONS

The utility of Bayesian methods for synthesizing qualitative and quantitative research findings at the participant level may depend on the nature of the relationship being synthesized and on how well the findings are represented in the individual reports.

Transforming verbal counts in reports of qualitative descriptive studies into numbers

Reports of qualitative studies typically do not offer much information on the numbers of respondents linked to any one finding. This information may be especially useful in reports of basic, or minimally interpretive, qualitative descriptive studies focused on surveying a range of experiences in a target domain, and its lack may limit the ability to synthesize the results of such studies with quantitative results in systematic reviews. Accordingly, the authors illustrate strategies for deriving plausible ranges of respondents expressing a finding in a set of reports of basic qualitative descriptive studies on antiretroviral adherence and suggest how the results might be used. These strategies have limitations and are never appropriate for use with findings from interpretive qualitative studies. Yet they offer a temporary workaround for preserving and maximizing the value of information from basic qualitative descriptive studies for systematic reviews. They show also why quantitizing is never simply quantitative.

Antiretroviral therapy in the lives of women of colour with HIV

Non-adherence to antiretroviral medication is associated with adverse patient outcomes. Considerable research and clinical work has focused on issues surrounding patient compliance to prescribed regimens. Few studies have explored the essence of antiretroviral medications in the lives of women of colour with HIV. A qualitative study of HIV-infected women of colour was undertaken in response to the question: What is the role of antiretroviral medication in your life? Taped interviews were conducted with graduate psychology students and commercially transcribed. Transcriptions were analyzed by Spiegelberg's category-cluster-theme process by four different reviewers. Three themes were distilled: trust/mistrust, approach/avoidance motivation and 'constantly tethered'. Strategies designed to increase medication adherence may need to consider these basic themes in order to be successful.

Gender, sexuality, and antiretroviral therapy: using social science to enhance outcomes and inform secondary prevention strategies

OBJECTIVES

To explore how, within the context of antiretroviral therapy (ART) uptake and adherence, social science research on gender and sexuality could complement existing epidemiological and behavioral research on uptake, adherence, disinhibition and reproduction.

METHODS

Bibliographical database searches on ART uptake and adherence, the sexual practices of HIV-positive individuals, and fertility management among HIV-positive men and women were conducted over a 6-month period using ISI Web of Science and Medline. Articles were sorted by main topic and then analysed to reveal the unarticulated assumptions that have framed research to date.

RESULTS

The adoption of more social scientific theoretical frameworks would move research on uptake, adherence, disinhibition, and reproduction among HIV-infected and affected individuals beyond the current overemphasis on how cognitive and ideological factors shape behavior and towards an understanding of how culture and inequality shapes the way people engage with ART and craft their sexual and reproductive lives. Research that pays greater attention to the social processes that create differentials in uptake and adherence, rather than just the quantification of those differentials, will open up new possibilities for community-based interventions. Similarly, social science research on gender and sexuality can provide insight into the social factors shaping reproductive and sexual behavior, and thus enhance our ability to manage the potentially competing priorities of limiting marital sexual risk and increasing access to reproductive choice among HIV-affected couples.

CONCLUSION

The ability to produce good clinical outcomes and to develop effective policies for secondary prevention will be enhanced by a deeper understanding of how gender inequality and the social organization of sexuality shape the sexual and reproductive behavior of individuals using ART.

Patients' Perceptions of Highly Active Antiretroviral Therapy in Relation to Treatment Uptake and Adherence

OBJECTIVE

To test the utility of the necessity-concerns framework in predicting highly active antiretroviral therapy (HAART) uptake and adherence.

METHODS

This was a prospective follow-up study. Consecutive patients who were not currently receiving HAART were referred by their HIV physician. Immediately after a recommendation of HAART, patients completed the Beliefs about Medicines Questionnaire assessing their perceptions of personal necessity for HAART and concerns about potential adverse effects. The influence of these beliefs on the decision to accept or decline HAART and adherence 12 months later were assessed.

RESULTS

One hundred fifty-three participants were given a recommendation of HAART, and 136 (88.9%) returned completed questionnaires. Thirty-eight participants (28%) initially rejected the treatment offer. Uptake of HAART was associated with perceptions of personal necessity for treatment (odds ratio [OR]=7.41, 95% confidence interval [CI]: 2.84 to 19.37) and concerns about potential adverse effects (OR=0.19, 95% CI: 0.07 to 0.48). There was a significant decline in adherence over time. Perceived necessity (OR=2.19, 95% CI: 1.02 to 4.71) and concerns about adverse effects (OR=0.45, 95% CI: 0.22 to 0.96), elicited before initiating HAART, predicted subsequent adherence. These associations were independent of clinical variables and depression.

CONCLUSIONS

The necessity-concerns framework is a useful theoretic model for understanding patient perspectives of HAART and predicting uptake and adherence, with implications for the design of evidence-based interventions.

Using qualitative metasummary to synthesize qualitative and quantitative descriptive findings

The new imperative in the health disciplines to be more methodologically inclusive has generated a growing interest in mixed research synthesis, or the integration of qualitative and quantitative research findings. Qualitative metasummary is a quantitatively oriented aggregation of qualitative findings originally developed to accommodate the distinctive features of qualitative surveys. Yet these findings are similar in form and mode of production to the descriptive findings researchers often present in addition to the results of bivariate and multivariable analyses. Qualitative metasummary, which includes the extraction, grouping, and formatting of findings, and the calculation of frequency and intensity effect sizes, can be used to produce mixed research syntheses and to conduct a posteriori analyses of the relationship between reports and findings.

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.

Investigating the decision-making needs of HIV-positive women in Africa using the Ottawa Decision-Support Framework: Knowledge gaps and opportunities for intervention

OBJECTIVE

To examine HIV-positive women's decision making in the context of pregnancy and HIV/AIDS and to explore interventions that may enhance and develop women's decision-making capacity in the sub-Saharan African context.

METHODS

The Ottawa Decision-Support Framework was used to assemble evidence of women's decision-making needs. Several electronic databases were searched and an Internet search of the World Wide Web was conducted to search grey literature sources. An evidence-based approach to assessing benefits, harms and current practices was employed.

RESULTS

Several gaps in our knowledge about women's decision making in the context of pregnancy and HIV were identified. The availability of evidence varied for each decision; however, significant gaps included: evidence around testing for ones status, advanced directives for self and child, disclosure (specifically, the impact of), others perceptions of antiretroviral use and data on termination of pregnancies.

CONCLUSION

Decision making as a concept was generally not addressed in the MTCT literature. Evidence regarding the perceptions of women and others regarding the various decisions was often not available and subsequently an important aspect of MTCT interventions neglected.

PRACTICE IMPLICATIONS

Incorporating a multi-disciplinary decision-support framework may prove useful to promote women's autonomy and involvement in MTCT-related decision making.

Adherence to HAART: a systematic review of developed and developing nation patient-reported barriers and facilitators

BACKGROUND

Adherence to highly active antiretroviral therapy (HAART) medication is the greatest patient-enabled predictor of treatment success and mortality for those who have access to drugs. We systematically reviewed the literature to determine patient-reported barriers and facilitators to adhering to antiretroviral therapy.

METHODS AND FINDINGS

We examined both developed and developing nations. We searched the following databases: AMED (inception to June 2005), Campbell Collaboration (inception to June 2005), CinAhl (inception to June 2005), Cochrane Library (inception to June 2005), Embase (inception to June 2005), ERIC (inception to June 2005), MedLine (inception to June 2005), and NHS EED (inception to June 2005). We retrieved studies conducted in both developed and developing nation settings that examined barriers and facilitators addressing adherence. Both qualitative and quantitative studies were included. We independently, in duplicate, extracted data reported in qualitative studies addressing adherence. We then examined all quantitative studies addressing barriers and facilitators noted from the qualitative studies. In order to place the findings of the qualitative studies in a generalizable context, we meta-analyzed the surveys to determine a best estimate of the overall prevalence of issues. We included 37 qualitative studies and 47 studies using a quantitative methodology (surveys). Seventy-two studies (35 qualitative) were conducted in developed nations, while the remaining 12 (two qualitative) were conducted in developing nations. Important barriers reported in both economic settings included fear of disclosure, concomitant substance abuse, forgetfulness, suspicions of treatment, regimens that are too complicated, number of pills required, decreased quality of life, work and family responsibilities, falling asleep, and access to medication. Important facilitators reported by patients in developed nation settings included having a sense of self-worth, seeing positive effects of antiretrovirals, accepting their seropositivity, understanding the need for strict adherence, making use of reminder tools, and having a simple regimen. Among 37 separate meta-analyses examining the generalizability of these findings, we found large heterogeneity.

CONCLUSIONS

We found that important barriers to adherence are consistent across multiple settings and countries. Research is urgently needed to determine patient-important factors for adherence in developing world settings. Clinicians should use this information to engage in open discussion with patients to promote adherence and identify barriers and facilitators within their own populations.

Research results have expiration dates: ensuring timely systematic reviews

Time and timeliness are key issues in appraising and ensuring the clinical relevance of systematic reviews. Time considerations entering the systematic review process include the history of the clinical problem, disease, or treatment that is the target of the review, and the history of the research conducted to address it. These considerations guide: (i) formulation of the research problems and questions; (ii) setting of parameters for the search and retrieval of studies; (iii) determination of inclusion and exclusion criteria; (iv) appraisal of the clinical relevance of findings; (v) selection of the findings that will be synthesized; and (vi) interpretation of the results of that synthesis.

The search for social validation and the sexual behavior of people living with HIV in Rio de Janeiro, Brazil: Understanding the role of treatment optimism in context

The primary aim of this qualitative study was to explore the influence of HIV treatment optimism on the sexual behavior of people living with HIV/AIDS (PLWHA) receiving highly active anti-retroviral therapy (HAART) at public health clinics in Rio de Janeiro, Brazil. We also explored the psycho-social dynamics of participants' sexual relationships in order to understand more broadly how these factors influence the sexual behavior of PLWHA and how they shape HAART-related beliefs. Twenty-three semi-structured, in-depth interviews were conducted with three groups: heterosexual women, heterosexual men and men who have sex with men living with HIV who reported being sexually active in the last year and were currently receiving HAART. We found that the availability of HAART was conceptualized as a rationale for unsafe sex among a minority of study participants and that this was more common among men than among women. Specific examples of treatment optimism appeared to be employed as a means to avoid acknowledging how deeper psychosocial issues may have been influencing participant's sexual behavior. Most participants' sexual behavior appeared largely to be a product of their desire for social validation and linked to feelings of shame and denial, including but not limited to HIV. Participants from all three groups expressed a considerable amount of fear and/or anxiety regarding behaviors such as disclosure and condom use as a result of the unexplored conflict between implementing these behaviors and continuing with their strategies for social validation within the context of their sexual relationships. We conclude that short-term information, education and communication interventions surrounding treatment optimism, disclosure and condom use are appropriate and necessary; but that they are not sufficient to address the core challenges to unsafe sex among PLHWA. These deep-rooted psychosocial issues may be better addressed by longer-term individual and group-level opportunities for exploration and critical reflection regarding sense of self and its relationship to social solidarity among PLWHA.

The social realities of adherence to protease inhibitor regimens: substance use, health care and psychological states

Adherence to HIV antiretroviral treatments is impacted by a variety of factors nested within the realities of people's lives. To understand this phenomenon, we undertook an investigation to assess HIV medication adherence in a community-based sample of 300 HIV seropositive men-who-have-sex-with-men (MSM). Using multiple measurement strategies (self-report, electronic monitoring, calendar-based assessments) we assessed factors related to medication adherence. Our findings indicate that adherence to protease inhibitor regimens are highly variable and are related to contextual, intrapersonal and behavioral factors, including access to health care, the use of specific recreational substances, self-efficacy toward adherence and avoidant coping strategies. These results suggest that a complex interaction between intrapsychic and socio-cultural realities may help to explain adherence to HIV treatment medications.

Quality Care for People with HIV/AIDS: patients' perspectives

PURPOSE

To explore patient preferences to aid in the development of quality measures to assess quality of health care for people living with human immunodeficiency virus/acquired immunodeficiency disease (HIV/AIDS).

METHOD

This study involved three 2-hour focus groups with 29 people living with HIV/AIDS in Portland, Oregon, and San Francisco, California. Eighteen quality of care indicators for HIV/AIDS health care were presented to each group and quantitative rankings were obtained. Aggregated weightings were used to rank and prioritize the quality measures for further exploration.

RESULTS

Participants identified 38 themes relevant to high-quality care for HIV/AIDS. Patients ranked the following candidate measures most important: effective relationship with provider, prevention of opportunistic infections, involvement in care and treatment decisions, being offered antiretroviral treatment, and access to health care services. We observed attitudinal differences among focus group participants that corresponded to gender and race/ethnicity.

CONCLUSION

Participants favored quality information that rated the experience of care and outcome measures including indicators of access to services, standard treatments, and competence of the providers. Patient perspectives can inform the development of quality measures that are meaningful to consumers and can assist in the design of services that meet patients' demographic and socioeconomic needs.

Integration of motivational interviewing and cognitive behavioral therapy to improve HIV medication adherence and reduce substance use among HIV-positive men and women: results of a pilot project

Directly addressing HIV medication adherence and substance use together is ideal in light of the research on the complex connections between these two behaviors. This paper describes the development of a pilot program in which a combined motivational interviewing and cognitive behavioral therapy intervention was used to increase adherence to highly active antiretroviral therapy (HAART) and reduce substance use in HIV-infected adults. The main goals of the pilot study were (1) to confirm the ability to recruit HIV-positive substance users taking HAART; (2) to demonstrate the ability to retain participants over the course of an eight-session intervention; and (3) to examine changes in substance use and HAART adherence from pretreatment to posttreatment. Twelve HIV-positive adults with a substance use disorder participated in an 8-week intervention, which consisted of weekly individual sessions with a trained therapist. Results showed that despite the small sample size, there was a significant reduction in substance use from pretreatment to posttreatment. No statistically significant differences were found for changes in HIV medication adherence, but the trends suggest the potential for positive results with a larger sample. Retention for all eight sessions of the treatment was 73.3%. Eighty percent completed the 3-month follow-up assessment. Participants reported high therapeutic alliance reflecting comfort with their therapists and in the treatment. Overall, the pilot demonstrated feasibility and acceptability of the treatment. Furthermore, results suggest that this may, in fact, be an effective intervention to reduce substance use and improve HIV medication adherence.

Cognitive reorganization and stigmatization among persons with HIV

BACKGROUND

A diagnosis of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) is a life-changing event, where persons must deal with a life-threatening, debilitating disease and its associated stigma and isolation. Studies over the past decade have shown that writing and talking about stressful and traumatic experiences, such as a life-threatening illness, causes emotions surrounding the trauma to change and to become cognitively reorganized. The result is a reduction in inhibition and change in basic cognitive and linguistic processes, which have contributed to meaningful behavioural, psychological, and physical health benefits across a variety of populations.

AIMS

To describe the construction of the Integrated Model of Health Promotion for persons with HIV/AIDS, and present initial empirical support of the model from a feasibility pilot study of women with HIV/AIDS.

APPROACH

The Integrated Model of Health Promotion is described and relevant literature in the field is reviewed. The model is implemented in a feasibility pilot study utilizing the emotional writing disclosure intervention.

RESULTS

Participants in the experimental condition demonstrated a promising pattern of cognitive reorganization, a reduced perception of stigma, and an improvement in mental health scores compared with the control condition.

CONCLUSION

Implications of these findings are discussed within the framework of the Integrated Model of Health Promotion. The model explores health and behavioural benefits associated with emotional writing in individuals with HIV/AIDS. The limited sample size of this pilot study precludes testing for significance. Further studies are required prior to the development of practice guidelines.

Motherhood in the context of maternal HIV infection

Metasummary and metasynthesis techniques were used to integrate findings pertaining to motherhood in 56 reports of qualitative studies conducted with HIV-positive women. Motherhood in the context of maternal HIV infection entailed work directed toward the illness itself and the social consequences of having HIV infection in the service of two primary goals: the protection of children from HIV infection and HIV-related stigma and the preservation of a positive maternal identity. Motherhood both intensified and mitigated the negative physical and social effects of HIV infection. HIV-positive mothers engaged in a distinctive kind of maternal practice-virtual motherhood-to resist forces that disrupted their relationships with and ability to care for their children, as well as their identities as mothers.

Classifying the findings in qualitative studies

A key task in conducting research integration studies is determining what features to account for in the research reports eligible for inclusion. In the course of a methodological project, the authors found a remarkable uniformity in the way findings were produced and presented, no matter what the stated or implied frame of reference or method. They describe a typology of findings, which they developed to bypass the discrepancy between method claims and the actual use of methods, and efforts to ascertain its utility and reliability. The authors propose that the findings in journal reports of qualitative studies in the health domain can be classified on a continuum of data transformation as no finding, topical survey, thematic survey, conceptual/thematic description, or interpretive explanation.

Toward a metasynthesis of qualitative findings on motherhood in HIV-positive women

A qualitative metasynthesis of qualitative findings ought to be more than a mere summary of those findings. Yet the processes by which the interpretive innovation expected of qualitative metasynthesis projects can be achieved remain opaque. Several analytic devices for the metasynthesis of findings were clarified in the course of an ongoing methodological project involving 45 reports of qualitative studies of HIV-positive women. These devices include the creation of a taxonomy of findings, the explicit use of sustained comparisons, the translation of in vivo concepts, and the use of imported concepts. Any qualitative metasynthesis of findings constitutes an interpretation at least three times removed from the lives represented in them. Clarifying the analytic devices used to create such metasyntheses is essential to demonstrating that despite being far away from participants' lives, these interpretations remain close to them.

Compliance with antiretroviral regimens to prevent perinatal HIV-1 transmission in Kenya

OBJECTIVE

To compare compliance and infant HIV-1 infection risk at 6 weeks with the Thai-CDC and HIVNET-012 antiretroviral regimens in a field setting.

DESIGN

Randomized clinical trial.

SETTING

Tertiary hospital antenatal clinic in Nairobi, Kenya.

PARTICIPANTS

HIV-1 infected women referred from primary care clinics.

INTERVENTIONS

Thai-CDC zidovudine regimen or HIVNET-012 nevirapine regimen.

MAIN OUTCOME MEASURES

Women were considered compliant if they used >or= 80% of the doses. Infants were tested for HIV-1 at 6 weeks. RESULTS Seventy women were randomized to Thai-CDC and 69 to HIVNET-012 regimens. More women were compliant with the antenatal (86%) than the intrapartum (44%) Thai-CDC regimen doses ( P= 0.001). Ninety-seven per cent took the maternal and 91% gave the infant dose of the HIVNET-012 regimen (P = 0.2). Overall, 41% were compliant with the Thai-CDC regimen and 87% with the HIVNET-012 regimen ( P< 0.001). Compliance with the Thai-CDC regimen was associated with partner support of antiretroviral use [odds ratio (OR), 3.0;, 95% confidence interval (CI), 1.0-9.1] and knowledge at recruitment that antiretroviral drugs could prevent infant HIV-1 (OR, 2.9; 95% CI, 1.0-8.1). Compliance with the HIVNET-012 regimen was associated with partner notification (OR, 8.0; 95% CI, 1.5-50) and partner willingness to have HIV-1 testing (OR, 7.5; 95% CI, 1.4-40). There was a trend for a higher risk of transmission with the HIVNET-012 regimen than with the Thai-CDC regimen (22% versus 9%; P= 0.07).

CONCLUSION

Compliance with the Thai-CDC and HIVNET-012 regimens was comparable to that in efficacy trials. Partner involvement, support and education on perinatal HIV-1 prevention may improve compliance and increase the number of infants protected from HIV-1 infection.

Detection and documentation of actual and potential medication adherence problems in patients receiving combination therapies

This article identifies problems in the documentation of antiretroviral medication adherence in medical records of clients seen in community-based treatment centers. Medical record data abstraction was conducted in community-based clinics providing HIV treatment services in a major HIV epicenter. Medical records of a purposive sample of 146 clients in four clinics were reviewed. Results revealed that adherence issues, in both frequency and type, were inadequately documented. Furthermore, when documented, reasons for patient adherence problems were not given. Documentation of follow-up of adherence issues was also absent in the medical records of study participants. There may be several unique and overlapping reasons for problems in documenting adherence issues: (a) provider experience and expertise in assessing adherence problems, (b) lack of sensitivity and specificity in clinician's assessments of adherence, (c) absence of adequate clinic protocol, and (d) available time to both assess adherence and complete thorough progress notes. This article provides data for the formulation of a summary adherence measure to enhance providers' abilities to detect and monitor actual and potential adherence problems.

Adherence to antiretroviral therapy among women with HIV infection

OBJECTIVE

The overall objective of this secondary analysis was to examine self-reported adherence to antiretroviral therapy in a sample of women with HIV.

DESIGN

The primary study used survey methodology.

SETTING

The setting included a university-based HIV/AIDS clinic in southwestern Pennsylvania and a community-based HIV/AIDS clinic in eastern Pennsylvania.

PARTICIPANTS

Sixty-one women infected with HIV who were taking protease inhibitors.

MAIN OUTCOME MEASURE

Self-reported adherence was based on responses to two questions: whether the person had missed a dose of her medications within the past 24 hours, and how many pills the person had taken on time as scheduled (none, very few, a few, about half, most, nearly all, all of them).

RESULTS

Adherence ranged from 60% to 75%. Two thirds (65.6%) of the sample thought that their medications were helping them; three fifths (57.4%) thought that it was dangerous to miss a dose of their medications.

CONCLUSIONS

Adherence in this sample was less than perfect, suggesting the need to develop, implement, and test interventions to promote better adherence to antiretroviral medication regimens among women with HIV.

Individual and system level factors associated with treatment nonadherence in human immunodeficiency virus-infected men and women

Antiretroviral treatment nonadherence is complex, implicating more than a patient's ability and motivation to be compliant. The bulk of the research to date focuses on individual level barriers with less emphasis on the many system level factors that potentially impact patients' adherence behaviors. This study examined the effects of system enabling factors in addition to the frequently studied individual predisposing and enabling factors upon nonadherence to treatment. One hundred eighty-two patients from five community-based clinics were interviewed and their medical charts examined. Patients' self-reported nonadherence was correlated with clinicians' assessments of medication and appointment nonadherence. Seven individual predisposing factors (gender, ethnicity, birthplace, years of education, HIV Overview of Problems-Evaluation System [HOPES] psychosocial, Hospital Anxiety and Depression Scale [HADS] anxiety, and HADS depression scores) were found to be significantly associated with treatment adherence/nonadherence. Individual enabling factors (hopefulness and access to health care), as well as treatment by clinic staff, a system enabling factor, were significantly associated with adherence/nonadherence. In a multivariate analysis, six factors - age (younger), gender (female), birth outside the United States, level of hopefulness (lower), access to health care (lower), and treatment by clinic staff (poorer) - accounted for 19.3% of the variance in nonadherence. Results of this study indicated that several individual predisposing and enabling factors were potential predictors of treatment nonadherence; however, system enabling factors, e.g., treatment by clinic staff were also associated with treatment nonadherence. Further studies are needed to examine the complex relationships of individual and system related factors in predicting treatment nonadherence.

Decisions about amniocentesis by advanced maternal age patients following maternal serum screening may not always correlate clinically with screening results: need for improvement in informed consent process

We evaluated the prenatal diagnosis utilization patterns of advanced maternal age (AMA) patients who underwent serum screening to assess how screening results correlated with their decisions regarding amniocentesis. A 6-year review (1994-1999) of laboratory records identified 2,456 AMA patients who underwent multiple-marker serum screening. The relationship between screening results and patients' decisions on whether or not to undergo amniocentesis was assessed. Among the 841 AMA patients with positive screens, more than half (52%) declined amniocentesis. Of the 1,615 patients with negative serum screening results, 208 (13%) opted for amniocentesis. We concluded that decisions by AMA patients regarding amniocentesis may not always correlate clinically with maternal serum screening results. Possible explanations, including how the state of informed consent may or may not contribute to these decisions, are discussed. It is suggested that understanding the reasons for these decisions may identify opportunities for improving service delivery to all pregnant patients considering prenatal testing. Use of a questionnaire is proposed as one mechanism for gaining a clearer understanding of the possible factors contributing to AMA patient decisions.

Factors associated with HIV-infected women's use or intention to use AZT during pregnancy

Despite the effectiveness of the antiviral drug AZT (zidovudine) in reducing perinatal transmission, many HIV-infected women continue to have reservations about taking the medication during pregnancy. To examine the factors influencing HIV-infected women's willingness to take AZT during pregnancy, focused interviews were conducted with 51 HIV-infected women of reproductive age living in New York City. Nearly all the women held reservations about taking it during pregnancy. Barriers to their use of AZT during pregnancy included (a) fear of toxic effects on baby, (b) fear of toxic effects for themselves, (c) fear of drug resistance, (d) belief that AZT is unnecessary among "healthy" women, and (e) previous birth to a healthy baby without using AZT. However, several factors also positively increased women's willingness to take AZT during pregnancy: (a) belief that they owe it to the baby to take AZT, (b) positive relationships with their physician, (c) peers or friends have taken AZT during pregnancy, and (d) previous experience taking AZT during pregnancy. These findings suggest significant areas for intervention to increase the use of AZT during pregnancy, thereby reducing perinatal transmission.

An investigation of why eligible patients do not receive HAART

Treatment with highly active antiretroviral therapy (HAART) decreases morbidity and mortality for persons with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and reduces costs of care. Yet many patients for whom HAART is indicated do not receive it. This study investigated the reasons why certain patients of a community health center with HIV/AIDS did not receive HAART between 1997 and 1998. Medical record reviews were performed to determine which patients for whom HAART was indicated (according to United States Public Health Service guidelines) were not prescribed HAART. Chart reviews and patient interviews were conducted to determine why they did not receive HAART. Of the 88 patients eligible for HAART, 60 (69%) had it prescribed in 1997-1998. Of the remaining 28 patients, 3 did not receive HAART because their provider never discussed it with them. For 6 patients (21%), the provider discussed HAART but did not recommend it; 16 patients (57%) declined HAART although their provider recommended it, and 3 (11%) accepted their provider's recommendation but never started HAART. Patients' most common reasons for refusing HAART were not being ready for strict adherence to a complex regimen (7/16) and fear of side effects (6/16). Other reasons included active drug use, religious beliefs, homelessness, confidentiality concerns, depression, and feeling well without HAART. Providers did not recommend HAART because of active drug use (4/6), lack of engagement with care (2/6) as well as homelessness, depression, and the perception that the patient was doing well without HAART. Providers should be trained to offer all patients the opportunity to develop a plan to address barriers to adherence and the support needed to implement it. Resources should also target the treatment of substance abuse and mental illness to improve the usage of HAART.

HIV-infected women's experiences and beliefs related to AZT therapy during pregnancy

To explore women's experiences and beliefs concerning zidovudine (AZT) therapy during pregnancy, short-answer and open-ended questions were asked of 322 human immunodeficiency virus (HIV)-infected women at increased risk for pregnancy. Specifically, we examined what women believed they had been told concerning AZT therapy during pregnancy by health care professionals and peers, experiences with taking AZT, how effective they believed AZT therapy to be, and if they would take AZT if they became pregnant. Women in the study were predominately African American (88%), single (79%), with a mean age of 32 years, and had annual incomes less than $10,000 (64%). Although 81.4% of the women had been told to take antiretrovirals, only 69.1% of the women were actually taking HIV-related medicines. Almost three-fourths of the women (70.8%) reported being told that taking AZT during pregnancy would reduce perinatal transmission. Women reported the most frequent reason for their stopping AZT was its side effects. When women who were not presently taking AZT were asked what would make them consider taking it, they most frequently said they would begin AZT if their health deteriorated or based on the advice of health care professionals. A small group of women said nothing would make them take AZT-type medications. More than one-half of the women said they felt AZT was effective in preventing perinatal HIV transmission. However, almost 20% of the women reported believing that their health care provider would not be positive about their taking AZT during pregnancy. Significant relationships were found between intent to take AZT if becoming pregnant and specific AZT-related beliefs and experiences.

Health care providers' influence on HIV-infected women's beliefs and intentions related to AZT therapy

This study examined how women's relationship with their primary health care provider (PHP) and their perceptions about how effective their PHPs believe zidovudine (AZT) to be in decreasing perinatal transmission related to women's AZT beliefs and intentions. It used a cross-sectional design to collect data from 59 HIV-infected African American women. Almost half the women (45%) had given birth since HIV diagnosis. Most of the babies born to HIV-infected mothers (87%) were seronegative. Data analysis with Pearson's r indicated that the quality of the women's relationship with their PHP was positively correlated to how important the PHP would be in decision making related to AZT therapy. Significant positive correlation was observed between women's perceptions about how effective their PHPs believed AZT to be in decreasing perinatal HIV transmission and the women's own beliefs about AZT, their intent to take AZT if pregnant, and intent to give AZT to a newborn.

Issues for women with heterosexually transmitted HIV disease

The encouraging outcome of new antiretroviral therapies has not been accompanied by a decrease in the incidence of HIV disease. There are reports of increases in AIDS in select geographical areas, minorities, and women. In 1997, 39% of cases in women were from heterosexual contact, whereas in men 7% of cases were from heterosexual contact. It is the most common mode of transmission in women globally and the only category of transmission in which the incidence of opportunistic infection has increased in the United States. Female anatomy, physiology, and sexual practices contribute to increasing risk of transmission, although there are no major biomedical differences in development of the disease related to gender. Two case examples illustrate the vulnerabilities, life-settings, pressures, and methods of coping for this population. Extensive discussion and review of the literature on the epidemiology, testing, disclosure, health care services, and prevention of transmission in women bring into focus strategies for improved education, diagnosis, care, and treatment.
