Optimal HAART adherence over time and time interval between successive visits: their association and determinants

Sociodemographic and health systems determinants of antiretroviral therapy adherence among human immunodeficiency virus-positive patients in the Volta Region of Ghana: A multi-centre study

Objectives

Optimal adherence to antiretroviral therapy is required for viral load suppression. This study investigated the sociodemographic (age, sex, marital status, level of education, monthly income, settlement type, distance to the antiretroviral therapy-providing site, ethnicity) and health system (antiretroviral therapy-providing site) determinants of antiretroviral therapy adherence among human immunodeficiency virus-positive patients in the Volta Region, Ghana.

Methods

A cross-section design was adopted, collecting data from 1729 human immunodeficiency virus patients and analysing them using STATA version 17 at level 0.05.

Results

Antiretroviral therapy adherence was poor (51.2%). Being divorced (Adjusted odds ratio (AOR) = 0.65), widow (AOR = 0.58), cohabiting (AOR = 0.22), Ewe (AOR = 3.7), Ga/Dangbe (AOR = 2.27), living in a rural area (AOR = 1.54) and an urban area (AOR = 0.64), having a monthly income of GH₵1000 or less (AOR = 3.21), covering a distance of 51 km and above to the antiretroviral therapy centre (AOR = 1.79), receiving antiretroviral therapy from Ketu South Municipal Hospital (AOR = 0.09), Hohoe Municipal Hospital (AOR = 0.03), Ho Municipal Hospital (AOR = 0.02) and Ho Teaching Hospital (AOR = 0.09) were the determinants of antiretroviral therapy adherence.

Conclusion

Antiretroviral therapy adherence was low. Interventions to improve antiretroviral therapy adherence should target these significant determinants.

The role of Nigerian medical students in the HIV response: lessons from the COVID-19 pandemic

Background: With the advent of the COVID-19 pandemic, this study seeks to understand how medical students' involvement in the HIV response during the COVID-19 pandemic - as well as before and after it - has influenced their decision to specialise in HIV care and their participation in HIV-related activities in the future.Method: Quantitative and qualitative approaches were utilised among medical students from Ambrose Alli University in their fourth, fifth and sixth years of study respectively. Data from this study was analysed using the SPSS version 21 module for descriptive statistics.Results: Medical students were more involved in community-based HIV awareness campaigns (48.6%) during the pre-COVID era, but then became more involved in online awareness campaigns (55%). Only 8.6% were involved in HIV research and evaluation activities. Over 31.2% of respondents were interested in specialising in HIV-related fields, with 23.6% attributing their decision to the COVID-19 pandemic. 92.3% of the respondents were of the opinion that medical students need to become more involved in HIV-related activities. There was statistical significance between the year of study of respondents and awareness of HIV-related activities (p < 0.007). Focused discussions revealed that all students felt that medical students should be more involved in HIV-related activities.Conclusion: Our results suggest that the COVID-19 pandemic marginally boosted the number of medical students involved in online awareness campaigns for HIV and AIDs, but there was decreased involvement in community campaigns and participation in community HIV testing. The impact of these findings on the lives of people living with HIV needs further investigation.

The Future of Telehealth in Human Immunodeficiency Virus Care: A Qualitative Study of Patient and Provider Perspectives in South Carolina

To ensure care continuity during the COVID-19 pandemic, telehealth has been widely implemented in human immunodeficiency virus (HIV) care. However, participation in and benefits from telehealth were unequal. This study aims to assess the willingness of people living with HIV (PWH) and HIV care providers to use telehealth and perceptions of the future role of telehealth. In-depth interviews with 18 PWH and 10 HIV care providers from South Carolina assessed their willingness to use telehealth, their perspectives on the future of telehealth in HIV care, and recommendations to improve telehealth. Interviews were analyzed using thematic analysis. Most PWH were female (61%), Black/African American (67%), and non-Hispanic (78%). Most PWH (61%) and all providers had used telehealth for HIV care. Most PWH and all providers reported being willing to use or (re-)consider telehealth HIV care services in the future. Providers suggested that telehealth is most suitable for routine HIV care encounters and for established, clinically stable, generally healthy PWH. Attitudes toward telehealth were heterogeneous, with most interviewees valuing telehealth similarly or superior to in-person care, yet >20% perceiving it less valuable. Recommendations to improve telehealth included multilevel strategies to address challenges across four domains: technology, the virtual nature of telehealth, administrative processes, and the sociodemographic profile of PWH. Telehealth in HIV care is here to stay; however, it may not yet be suitable for all PWH and all care encounters. Decision processes related to telehealth versus in-person care need to involve providers and PWH. Existing telehealth options require multilevel adjustments addressing persistent challenges.

Socio-Demographic, Economic and Clinical Predictors for HAART Adherence Competence in HIV-Positive Adults at Felege Hiwot Teaching and Specialized Hospital, North West Ethiopia

Background

Currently, around 36.7 million people in the world are living with HIV. Among these, 52% are living in sub-Saharan Africa. The main objective of this study was to identify socio-demographic economic and clinical factors associated with HAART adherence competence in successive visits among adult HIV patients after commencement of their treatment.

Methods

A retrospective cohort study design was conducted on a random sample of 792 treatment attendants. The samples were selected using stratified random samples technique considering their residence area as strata. Secondary data were used in this study. Structural equation modeling (SEM) was applied to identify predictors of HAART adherence competence over time.

Results

In this longitudinal study, factors affecting long-term HAART adherence competence in successive visits were identified. Among the predictors, marital status (mean = 3.97, variance = 0.6, p = 0.021), level of disclosure of the disease (mean = 6.24, variance = 0.29, p = 0.012), residence area (mean = 3.97, variance = 0.6, p = 0.021), level of education (mean = 2.04, variance= 0.81, p = 0.012), ownership of cell phone (mean = 2.99, variance = 0.68, p = 0.034), household income (mean = 6.37, variance = 0.53, p = 0.002), age of patients (mean = –2.78, variance = 56.64, p = 0.023), sex of patients (mean = –1.25, variance = 0.88, p = 0.036), weight (mean = –2.89, 42.36, p = 0.001), initial CD4 cell count (mean = 2.57, variance = 158.48, p = 0.015) and WHO stages (mean = 2.37, variance = 0.78, p = 0.026) were directly associated with retention of medication care. On the other hand, medication care was significantly and independently associated with longitudinal adherence competence.

Conclusion

The outcome variable in successive visits increased with the number of follow-up visits, but the rate of increase was different for different groups, such as urban and rural, and for those patients disclosing and not disclosing the disease to family members. An integrated health-related education should be given for non-adherent patients like rural residents, patients living without partners, patients with no cell phone and aged patients.

Association between HIV stigma and antiretroviral therapy adherence among adults living with HIV: baseline findings from the HPTN 071 (PopART) trial in Zambia and South Africa

OBJECTIVES

Adherence to antiretroviral therapy (ART) leads to viral suppression for people living with HIV (PLHIV) and is critical for both individual health and reducing onward HIV transmission. HIV stigma is a risk factor that can undermine adherence. We explored the association between HIV stigma and self-reported ART adherence among PLHIV in 21 communities in the HPTN 071 (PopART) trial in Zambia and the Western Cape of South Africa.

METHODS

We conducted a cross-sectional analysis of baseline data collected between 2013 and 2015, before the roll-out of trial interventions. Questionnaires were conducted, and consenting participants provided a blood sample for HIV testing. Poor adherence was defined as self-report of not currently taking ART, missing pills over the previous 7 days or stopping treatment in the previous 12 months. Stigma was categorised into three domains: community, health setting and internalised stigma. Multivariable logistic regression was used for analysis.

RESULTS

Among 2020 PLHIV self-reporting ever taking ART, 1888 (93%) were included in multivariable analysis. Poor ART adherence was reported by 15.8% (n = 320) of participants, and 25.7% (n = 519) reported experiencing community stigma, 21.5% (n = 434) internalised stigma, and 5.7% (n = 152) health setting stigma. PLHIV who self-reported previous experiences of community and internalised stigma more commonly reported poor ART adherence than those who did not (aOR 1.63, 95% CI 1.21 -2.19, P = 0.001 and aOR 1.31, 95% CI 0.96-1.79, P = 0.09).

CONCLUSIONS

HIV stigma was associated with poor ART adherence. Roll-out of universal treatment will see an increasingly high proportion of PLHIV initiated on ART. Addressing HIV stigma could make an important contribution to supporting lifelong ART adherence.

Evidence of reduced treatment adherence among HIV infected paediatric and adolescent populations in Nairobi at the onset of the UNAIDS Universal Test and Treat Program

OBJECTIVE

We conducted a retrospective cohort study to evaluate the efficacy of the World Health Organization (WHO) "Universal Test and Treat" (UTT) policy, initiated in Kenya in September 2016. Under this policy, every human immunodeficiency virus (HIV)-infected person should be initiated on antiretroviral therapy (ART). We compared intra- and inter-group viral suppression and ART adherence rates for pre-UTT (initiated on ART in March-August 2016) and UTT groups (initiated in September 2016). The study was conducted in a community outreach Program in Nairobi with 3500 HIV-infected children enrolled.

RESULTS

122 children and adolescents were initiated on first-line ART pre-UTT, and 197 during the UTT period. The 6 month viral suppression rate was 79.7% pre-UTT versus 76.6% UTT (P < 0.05). Suboptimal adherence was higher in the UTT than pre-UTT period (88 of 197, 44.7% and 44 of 122, 34%; P < 0.001). The decrease in adherence was greater among orphans (91.7% pre-UTT and 87.2% UTT, P = 0.001) and children 11-18 years. Our results show that successful implementation of the UTT policy in Africa is challenged by an increased risk of suboptimal adherence. There is a need to develop extra strategies to support adherence, especially among orphans and teenagers.

Joint longitudinal data analysis in detecting determinants of CD4 cell count change and adherence to highly active antiretroviral therapy at Felege Hiwot Teaching and Specialized Hospital, North-west Ethiopia (Amhara Region)

BACKGROUND

Adherence and CD4 cell count change measure the progression of the disease in HIV patients after the commencement of HAART. Lack of information about associated factors on adherence to HAART and CD4 cell count reduction is a challenge for the improvement of cells in HIV positive adults. The main objective of adopting joint modeling was to compare separate and joint models of longitudinal repeated measures in identifying long-term predictors of the two longitudinal outcomes: CD4 cell count and adherence to HAART.

METHODS

A longitudinal retrospective cohort study was conducted to examine the joint predictors of CD4 cell count change and adherence to HAART among HIV adult patients enrolled in the first 10 months of the year 2008 and followed-up to June 2012. Joint model was employed to determine joint predictors of two longitudinal response variables over time. Furthermore, the generalized linear mixed effect model had been used for specification of the marginal distribution, conditional to correlated random effect.

RESULTS

A total of 792 adult HIV patients were studied to analyze the longitudinal joint model study. The result from this investigation revealed that age, weight, baseline CD4 cell count, ownership of cell phone, visiting times, marital status, residence area and level of disclosure of the disease to family members had significantly affected both outcomes. From the two-way interactions, time * owner of cell phone, time * sex, age * sex, age * level of education as well as time * level of education were significant for CD4 cell count change in the longitudinal data analysis. The multivariate joint model with linear predictor indicates that CD4 cell count change was positively correlated (p ≤ 0.0001) with adherence to HAART. Hence, as adherence to HAART increased, CD4 cell count also increased; and those patients who had significant CD4 cell count change at each visiting time had been encouraged to be good adherents.

CONCLUSION

Joint model analysis was more parsimonious as compared to separate analysis, as it reduces type I error and subject-specific analysis improved its model fit. The joint model operates multivariate analysis simultaneously; and it has great power in parameter estimation. Developing joint model helps validate the observed correlation between the outcomes that have emerged from the association of intercepts. There should be a special attention and intervention for HIV positive adults, especially for those who had poor adherence and with low CD4 cell count change. The intervention may be important for pre-treatment counseling and awareness creation. The study also identified a group of patients who were with maximum risk of CD4 cell count change. It is suggested that this group of patients needs high intervention for counseling.

Determinants of adherence to antiretroviral therapy among HIV-positive adults in sub-Saharan Africa: a systematic review

OBJECTIVE

The rapid scale up of antiretroviral treatment (ART) in sub-Saharan Africa (SSA) has resulted in an increased focus on patient adherence. Non-adherence can lead to drug-resistant HIV caused by failure to achieve maximal viral suppression. Optimal treatment requires the identification of patients at high risk of suboptimal adherence and targeted interventions. The aim of this review was to identify and summarise determinants of adherence to ART among HIV-positive adults.

DESIGN

Systematic review of adherence to ART in SSA from January 2002 to October 2014.

METHODS

A systematic search was performed in 6 databases (PubMed, Cochrane Library, EMBASE, Web of Science, Popline, Global Health Library) for qualitative and quantitative articles. Risk of bias was assessed. A meta-analysis was conducted for pooled estimates of effect size on adherence determinants.

RESULTS

Of the 4052 articles screened, 146 were included for final analysis, reporting on determinants of 161 922 HIV patients with an average adherence score of 72.9%. Main determinants of non-adherence were use of alcohol, male gender, use of traditional/herbal medicine, dissatisfaction with healthcare facility and healthcare workers, depression, discrimination and stigmatisation, and poor social support. Promoters of adherence included counselling and education interventions, memory aids, and active disclosure among people living with HIV. Determinants of health status had conflicting influence on adherence.

CONCLUSIONS

The sociodemographic, psychosocial, health status, treatment-related and intervention-related determinants are interlinked and contribute to optimal adherence. Clinics providing ART in SSA should therefore design targeted interventions addressing these determinants to optimise health outcomes.

Challenges in initiating antiretroviral therapy for all HIV-infected people regardless of CD4 cell count

Introduction

Recently published large randomized controlled trials, START, TEMPRANO and HPTN 052 show the clinical benefit of early initiation of antiretroviral treatment (ART) in HIV-infected persons and in reducing HIV transmission. The trials influenced the World Health Organization (WHO) decision to issue updated recommendations to prescribe ART to all individuals living with HIV, irrespective of age and CD4 cell count.

Discussion

It is clear that the new 2015 WHO recommendations if followed, will change the face of the HIV epidemic and probably curb its burden over time. Implementation however, requires that health systems, especially those in low and middle-income settings, be ready to face this challenge on a large scale. HIV prevention and treatment are easy in theory yet hard in practice. The new WHO guidelines for initiation of ART regardless of CD4 cell count will lead to upfront increases in the costs of healthcare delivery as the goal is to treat all those now newly eligible for ART. Around 22 million people living with HIV qualify and will therefore require ART. Related challenges immediately follow: firstly, that everyone must be tested for HIV; secondly, that anyone who has had an HIV test should know their result and understand its significance; and, thirdly, that every person identified as HIV-positive should receive and remain on ART. The emergence of HIV drug resistant strains when treatment is started at higher CD4 cell count thresholds is a further concern as persons on HIV treatment for longer periods of time are at increased risk of intermittent medication adherence.

Conclusions

The new WHO recommendations for ART are welcome, but lacking as they fail to consider meaningful solutions to the challenges inherent to implementation. They fail to incorporate actual strategies on how to disseminate and adopt these far-reaching guidelines, especially in sub-Saharan Africa, an area with weak healthcare infrastructures. Well-designed, high-quality research is needed to assess the feasibility, safety, acceptability, impact, and cost of innovations such as the universal voluntary testing and immediate treatment approaches, and broad consultation must address community, human rights, ethical, and political concerns.
