Incidence and Predictors of Viral Load Suppression After Enhanced Adherence Counseling Among HIV-Positive Adults in West Gojjam Zone, Amhara Region, Ethiopia

Adherence of healthcare providers to Enhanced Adherence Counseling (EAC) intervention protocol in West Amhara Public Health Facilities, Northwest Ethiopia, 2023: mixed method evaluation

BACKGROUND

In Ethiopia, there were an estimated 670,906 people living with the Human Immune Virus (HIV). Implementing an HIV test and treat strategy and rapid scale-up of anti-retroviral treatment (ART) provided health facilities increased the number of the number of people living with HIV/AIDS. In the same way, the expansion of viral load monitoring in these health facilities and poor adherence to ART increase the number of high-viral load (HVL) patients. To alleviate this problem, the World Health Organization (WHO) recommended EAC intervention for HVL patients. Therefore, the aim of this research was to determine the level of healthcare providers' adherence to the EAC intervention protocol and explore barriers and facilitators of the intervention in West Amhara, Northwest Ethiopia.

METHOD

Descriptive cross-sectional study design with concurrent mixed-method evaluation was employed. The adherence dimension, with its sub-dimensions of content, coverage, frequency, and duration of the EAC intervention, was used with sixteen indicators. A total of 20 high-case-load public health facilities and 173 HVL patients were included in our study. Quantitative data was entered into Epi Info and exported to SPSS version 25 for analysis. Descriptive statistics are analyzed in terms of frequencies, percentages, variances, and means and presented as narrations, frequency tables, graphs, and charts. Qualitative data were transcribed, translated, coded, and analyzed thematically using Open Code version 4.0 software. The qualitative findings were used to triangulate the quantitative findings.

RESULT

The average adherence level of health care providers (HCPs) to the EAC intervention protocol was 55.3%, from which content, coverage, frequency, and duration of the intervention contributed 70.3%, 86.3%, 36.9%, and 27.7%, respectively. Most of the intervention contents were delivered during the session, but none of the providers developed a patient adherence plan at the end of the session. All HVL patients were linked and enrolled in the EAC intervention. But only 6% of them were tested for repeat VL.

CONCLUSION

The average adherence level of HCPs to the EAC intervention protocol was very inadequate. The main gap identified was difficulties in completing the EAC intervention sessions based on schedules. Implementing adherence improvement strategies, assigning an adequate number of EAC providers in ART and Prevention of Mother-to-Child Transmission (PMTCT) clinics, and allowing sufficient time during EAC sessions are important.

Predictors of successful transition of adolescents and young adults living with HIV from pediatric to adult-oriented care in southern Ethiopia: a retrospective cohort study

BACKGROUND

The introduction of highly active antiretroviral therapy has significantly improved the life expectancies of children and adolescents living with HIV, leading to an increased number transitioning to adult care. However, there has been a lack of studies in Ethiopia focusing on factors influencing the success of this transition. Therefore, this study aimed to determine predictors of a successful transition from pediatric to adult HIV clinics among adolescents and young adults living with HIV in health facilities in southern Ethiopia.

METHODS

A retrospective cohort study included 337 adolescents and young adults who transitioned to adult-oriented HIV care. Successful transition was defined as having a viral load of less than 1000 copies/ml and maintaining care during the first year post-transition. Patients' antiretroviral therapy (ART) cards and monitoring charts were reviewed. Secondary data analysis was conducted using a multivariable binary logistic regression model to identify predictors of a successful transition. Using the variance inflation factor, we checked for multi-collinearity between variables and assessed model fitness with the Hosmer and Lemeshow goodness-of-fit test. Adjusted Odds Ratio (AOR) with 95% confidence intervals (CI) and P-value ≤ 0.05 measured the strength of association and statistical significance.

RESULTS

Of 337 participants, 230 (68.25%) successfully transitioned (95% CI = 63.25, 73.25). Transitioning at age 18 or older (AOR = 4.25; 95% CI = 2.29, 7.87), residing in an urban area (AOR = 1.78; 95% CI = 1.04, 3.02), and being on antiretroviral therapy for more than two years (AOR = 4.25; 95% CI = 1.17, 4.94; P < 0.017) were identified as positive predictors and opportunistic infection (AOR = 0.34; 95% CI = 0.15, 0.75; P < 0.008) was identified as a negative predictor for a successful transition from pediatric to adult ART clinic.

CONCLUSION

This study sheds light on the challenges faced by HIV patients transitioning from pediatric to adult care, with less than 70% successfully navigating this critical phase. Factors such as age at transition, residence, duration of ART, and the presence of opportunistic infections were identified as key predictors of successful transition. The findings underscore the urgent need for tailored interventions, including standardized transition plans that address age and urban/rural disparities, to enhance transition outcomes for adolescents and young adults living with HIV in the region.

Viral load suppression and its predictor among HIV seropositive people who receive enhanced adherence counseling at public health institutions in Bahir Dar, Northwest Ethiopia. Retrospective follow-up study

BACKGROUND

For those HIV seropositive people with high viral loads, the World Health Organization recommends more counseling before changing ART regimens. A high viral load can lead to increased HIV transmission and lower survival rates. Clients with viral loads above 1000 copies/mL should receive enhanced adherence counseling for 3-6 months before switching. Despite enhanced adherence counseling programs, most countries struggle with viral load suppression. Little is known about viral load suppression in Ethiopia and the research area after counseling.

OBJECTIVE

This study aims to assess viral load suppression and its predictors among HIV-positive individuals receiving enhanced adherence counseling in Bahir Dar, Northwest Ethiopia, in 2022.

METHODS

An institution-based retrospective follow-up study was conducted among randomly selected 546 clients on Enhanced Adherence Counseling at public health facilities in Bahir Dar city. The Epicollect5 mobile application was used to collect the data, which was then exported to Stata version 14 for analysis. A Log-Binomial regression model was fitted for each explanatory variable. Variables having a p-value <0.25 in bivariate analysis were entered into a multivariable Log-Binomial regression model. Finally, an adjusted risk ratio with a 95% confidence interval and a p-value <0.05 was used to measure the strength of the prediction.

RESULTS

Following enhanced adherence counseling, 312 (57.1%) people had their viral load suppressed. Absence of recurrent OI (ARR 1.40; CI 1.03-1.91), EAC stay less than 3 months (ARR 1.54; CI 1.19-1.99), EAC stay 3-6 months (ARR 1.38; CI 1.12-1.69), once-daily ARV dose regimen (ARR 1.28; CI 1.03-1.58), baseline viral load of 2879.00 copies/ml (ARR 1.30, CI 1.06-1.60), being orthodox Tewahido Christian (ARR 0.37; CI 0.18-0.75) were significant predictors of viral load suppression after Enhanced Adherence Counseling.

CONCLUSION AND RECOMMENDATION

Most importantly, this study found that most people had suppressed viral loads after receiving enhanced adherence counseling. Significant predictors of viral load suppression included recurrent OI, length of stay on EAC, daily ARV dosing regimen, baseline viral load, and religion. Clients with a high baseline viral load and those who experience recurring opportunistic infections should get extra care during EAC sessions.

Virological Suppression and its Predictors Among HIV/AIDS Patients on Antiretroviral Therapy in Ethiopia: Systematic Review and Meta-analysis

Background

Achieving viral load suppression is crucial for the prevention of complications and deaths related to HIV infection. Ethiopia has embraced the worldwide 95-95-95 target, but there is no national representative information regarding virological suppression. Therefore, this review aims to determine the pooled virological suppression rate and identify the pooled effect of contributing factors of viral suppression for HIV-positive patients on antiretroviral therapy in Ethiopia.

Methods

We systematically searched websites and databases, including online repositories, to obtain primary studies. Two reviewers assessed the quality of the included articles using the Newcastle-Ottawa Scale appraisal checklist. Publication bias was checked using Egger's regression test, the heterogeneity of the studies was assessed using I2 statistics and Q statistics, and a sensitivity analysis was performed to identify any outlier results in the included studies. The Der Simonian Laird random-effects model was used to estimate the overall proportion of viral suppression, and STATA 17 statistical software was used for all types of analysis.

Results

A total of 21 eligible articles primarily conducted in Ethiopia using HIV program data were used for this quantitative synthesis. The overall pooled virological suppression rate was 71% (95% CI, 64%-77%). The pooled effects of poor adherence to ART (adjusted odds ratio [AOR], 0.33; 95% CI, 0.28-0.40), body mass index (18.5-24.9 kg/m2; AOR, 1.8; 95% CI, 1.37-2.36), disclosure (AOR, 1.41; 95% CI, 1.05-1.89), absence of opportunistic infection (AOR, 1.68; 95% CI, 1.43-1.97), and high baseline viral load count (AOR, 0.65; 95% CI, 0.52-0.81) were identified as significant predictors of viral suppression.

Conclusions

The overall pooled percentage of virological suppression was low compared with the global target of viral suppression and the Ethiopian Public Health Institute report. Poor adherence, normal body mass index, disclosure, absence of opportunistic infection, and high baseline viral load count were factors contributing to viral suppression in Ethiopia. Responsible stakeholders should maximize their efforts to achieve the global target of virological suppression by addressing significant predictors.

Virological Non-Suppression, Non-Adherence and the Associated Factors Among People Living with HIV on Dolutegravir-Based Regimens: A Retrospective Cohort Study

Background

HIV is one of the leading causes of morbidity and mortality, with 39.0 million people living with HIV worldwide, 25.6 million of whom reside in the African region. Highly active anti-retroviral therapy (HAART) has improved survival and quality of life, yet some patients develop viral non-suppression. Dolutegravir (DTG) has been recommended since 2018 as a first-line treatment option in low- and middle-income countries owing to its effectiveness, low cost, and tolerability, but some studies have reported virological non-suppression with its use. This study aims to explore the prevalence and factors associated with virological non-suppression in adults taking DTG-based regimens in Mbarara Regional Referral Hospital.

Methods

A retrospective cohort study was carried out among people living with HIV (PLWHIV) taking DTG-based HAART regimens by way of record review. SPSS was used for analysis, and both binary and multivariate logistic regression analyses were performed to test associated factors.

Results

Among the 422 participants' records reviewed, 62.8% were female (median age 40 years, IQR=13). The prevalence of virological non-suppression was 4.2%. Poor adherence to HAART was significantly associated with virological non-suppression, with 100.3 increased adjusted odds (95% CI: 28.90-348.12, p<0.001) compared to those with a record of good adherence. The reasons for poor adherence included alcohol use, stigma, forgetting to take medication, transport problems, and irregular timing of swallowing.

Conclusion

This study found poor adherence to be associated with a 4.2% prevalence of virological non-suppression among PLWHIV in a large public HIV care clinic. Despite the high suppression rates on DTG-based regimens, adherence counseling and viral load monitoring need to be emphasized at all HIV care centers to mark the trends of virological non-suppression.

Providing anti-retroviral treatment did not achieve the ambition of 'Joint united nations program on HIV/AIDS (UNAIDS) among HIV positive patient in Ethiopia': a systematic review and meta-analysis

Introduction

Antiretroviral Treatment (ART) has great importance in reducing viral load. Though a global effort was made to suppress viral load, the level of viral load suppression among ART patients is still high in Ethiopia.

Objective

This study aims to assess the magnitude and contributing factors for viral load suppression among patients attending ART clinics in Ethiopia.

Methods

The articles were searched using different databases using the guideline of reporting systematic review and meta-analysis (PRISMA). A random effect model was used to ascertain the pooled prevalence of viral load suppression in Ethiopia using STATA 14 software.

Results

The pooled prevalence of suppressed viral load was 75.25% (95% CI: 68.61-81.89). Having good adherence (OR: 2.71, 95% CI 2.27, 3.15), baseline CD4 count (OR: 1.74, 95% CI 1.53, 1.96), and being female (OR: 1.41, 95% CI 1.04, 1.79) were determinants of pooled estimates of suppressed viral load.

Conclusion

The pooled prevalence of suppressed viral load was 75% which is lower than the targeted level by the sustainable development goal (SDG) 2020, which was 90%. Therefore, the stakeholders should be focused on the existing strategies to decrease viral load among ART patients. They should work to adhere to patients for ART treatment.

The effect of mobile phone utilization for enhanced adherence counselling intervention among persons with HIV

The conduct of physical enhanced adherence counselling (EAC) for antiretroviral therapy (ART) non-adherers is often flawed by objectionable time lag from commencement to timely completion of the process. Therefore, we conducted a retrospective cohort study of 342 adults (≥18 years) with HIV on ART to determine the outcome of utilizing mobile phone based EAC intervention. Structural equation modelling framework, with full information maximum likelihood estimator was used to elucidate the pathways linking the relationship between individual characteristics, perceived barriers to ART adherence, and the applied interventions. A total of 321(93.9%) participants completed the required 3 EAC sessions over 60-days. The proportion of viral load (VL) re-suppression (<1000 copies/mL) after EAC intervention was 66.6%. The mean durations of EAC onset from time of high VL confirmation and completion of EAC were 6.26 ± 3.22 and 59.99 ± 5.14 days, respectively. In the simultaneous model (Comparative Fit Index = 0.89, Tucker-Lewis Index = 0.851, Root Mean Square (RMS) Error of Approximation = 0.049, Standardized RMS Residual = 0.059), the variables: forgot, knowledge/beliefs, side effect of drugs, lost/ran out of drugs, scheduling, and stigma were significant barrier factors contributing to poor ART adherence. The use of mobile phones for EAC intervention was effective for early initiation and timely completion of the sessions.

Time to Virological Failure and Its Predictor Among HIV-Positive Clients with the Differentiated Service Delivery Model of HIV at Debre Berhan Comprehensive Specialized Hospital, Amhara Regional State, Ethiopia, 2021: A Retrospective Cohort Study

Diversified antiretroviral therapy (ART) approach is needed in methods that were acceptable to communities and maintain good viral suppression outcomes to reach the UNAIDS targets to end the HIV/AIDS epidemic by 2030. Ethiopia is fully implementing differentiated service delivery (DSD) approaches, appointment spacing, and standard care. This study aimed to determine the time to HIV virological failure and its predictors among patients with a DSD model. An institution-based retrospective cohort study was conducted with data collection dates ranging from May 1, 2021, to May 30, 2021. All adult HIV-positive patients (n = 2,148) between January 2018 and January 2021 were a source population. Data were extracted using a standard checklist by trained data collectors and entered into EpiData, exported to SPSS version 20 for data management, and then exported to R Studio version 1.4 for analysis. Kaplan-Meier survival curves, the log-rank test, and Cox proportional hazard regression models were employed. The incidence of virological failure was 86 per 10,000 person-months. The independent predictors for the hazard of virological failure were being on standard care [adjusted hazard ratios (AHR) = 1.91; 95% confidence interval (CI) 1.07-3.40], primarily educated (AHR = 3.46; 95% CI 1.02-11.72), having no education (AHR = 3.45; 95% CI 1.01-11.85), and ambulatory status at baseline (AHR = 1.81; 95% CI 1.06-3.09). Patients who had a viral load with a detectable range from 50 to 999 at engagement (AHR = 2.65; 95% CI 1.33-5.27) and a 1-month increase in ART for HIV patients (AHR = 1.045; 95% CI 1.01-1.09). The incidence of virological failure was 86 per 10,000 person-months, whereas the incidences were 52 per 10,000 person-months and 71 per 10,000 person-months on appointment spacing model and standard care, respectively, with independent predictors: patient category, educational status, baseline functional status, viral load at engagement, and duration of ART.

Time to Viral Load Suppression and Its Predictors Among Adult Patients on Antiretro Viral Therapy in Nigist Eleni Mohammed Memorial Comprehensive Specialized Hospital, Hossana, Southern Ethiopia

Background

Unsuppressed viral load count in patients on anti-retroviral therapy is linked to poorer survival and increased transmission of the virus. Despite efforts made in Ethiopia, the viral load suppression rate is still low.

Objective

To estimate time to viral load suppression and predictors of viral load suppression among adults on anti-retroviral therapy in Nigist Elen Mohamed Memorial Comprehensive Specialized Hospital, 2022.

Materials and Methods

A retrospective follow-up study was conducted among 297 adults on anti-retroviral therapy from January 1, 2016, to December 31, 2021. A simple random sampling technique was used to select study participants. The data were analyzed using STATA 14. Cox regression model was used. The adjusted hazard ratio with 95% CI was estimated.

Results

A total of 296 records of patients on anti-retroviral therapy were included in this study. The incidence of viral load suppression was 9.68 per 100-person months. The median time for viral load suppression was 9 months. Patients with baseline CD4 ≥200 cell/mm³ (AHR: 1.87; 95% CI = 1.34, 2.63), who had no opportunistic infections (AHR = 1.84; 95% CI = 1.34, 2.52), who were on WHO clinical stage-I or II (AHR = 2.12; 95% CI = 1.18, 3.79) and who have taken tuberculosis preventive therapy (AHR = 2.24; 95% CI = 1.66, 3.02) had higher hazards of viral load suppression.

Conclusion

The median time for viral load suppression was 9 months. Patients who had no opportunistic infection, with higher CD4 count, on WHO clinical stage-I or II, who have taken tuberculosis preventive therapy had higher hazards of viral load suppression. Careful monitoring and counseling of patients with CD4 levels lower than 200 cells/mm3 are necessary. Careful monitoring and counseling of patients in advanced WHO clinical stages, with lower CD4 count levels and with opportunistic infections is crucial. Strengthening the provision of tuberculosis preventive therapy is warranted.
