Discrepancies between self-reported medication in adherence and indirect measurement adherence among patients undergoing antiretroviral therapy: a systematic review. Infect Dis Poverty 2024; 13:51. [PMID: 38970140 PMCID: PMC11225374 DOI: 10.1186/s40249-024-01221-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2024] [Accepted: 06/24/2024] [Indexed: 07/07/2024] Open
Abstract
BACKGROUND Given the critical importance of medication adherence in HIV/AIDS treatment, this study aims to compare medication adherence measured by self-report (SR) and indirect measurement among antiretroviral therapy (ART) patients, exploring the differences of adherence results measured by different tools. METHODS We systematically searched PubMed, Embase, and the Cochrane Library to identify all relevant literature published up to November 22, 2023, without language restrictions, reporting adherence to ART measured by both SR and indirect measurement methods, while also analyzing individual and group adherence separately. Discrepancies between SR and indirect measurement results were assessed using the Mann-Whitney U test or Wilcoxon signed-rank test, with correlations evaluated using the Pearson correlation coefficient. Following one-to-one comparisons, meta-epidemiological one-step analysis was conducted, and network meta-analysis techniques were applied to compare results obtained through specific adherence assessment tools reported in the identified articles. RESULTS The analysis encompassed 65 original studies involving 13,667 HIV/AIDS patients, leading to 112 one-to-one comparisons between SR and indirect measurement tools. Statistically significant differences were observed between SR and indirect measurement tools regarding both individual and group adherence (P < 0.05), with Pearson correlation coefficients of 0.843 for individual adherence and 0.684 for group adherence. During meta-epidemiological one-step analysis, SR-measured adherence was determined to be 3.94% (95% CI: -4.48-13.44%) higher for individual adherence and 16.14% (95% CI: 0.81-18.84%) higher for group adherence compared to indirectly measured results. Subgroup analysis indicated that factors such as the year of reporting and geographic region appeared to influence the discrepancies between SR and indirect measurements. Furthermore, network meta-analysis revealed that for both individual and group adherence, the results obtained from most SR and indirect measurement tools were higher than those from electronic monitoring devices, with some demonstrating statistical significance (P < 0.05). CONCLUSIONS The findings underscored the complexity of accurately measuring medication adherence among ART patients. Significant variability was observed across studies, with self-report methods showing a significant tendency towards overestimation. Year of reporting, geographic region, and adherence measurement tools appeared to influence the differences between SR and indirect measurements. Future research should focus on developing and validating integrated adherence measurements that can combine SR data with indirect measures to achieve a more comprehensive understanding of adherence behaviors.

Forgetting to Take Medication, Treatment Adherence and Their Relationship with Viral Load Suppression Among People Living with HIV in the Kilimanjaro Region, Tanzania. HIV AIDS (Auckl) 2024; 16:245-257. [PMID: 38911143 PMCID: PMC11192192 DOI: 10.2147/hiv.s452875] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2023] [Accepted: 05/17/2024] [Indexed: 06/25/2024] Open
Abstract
Background Antiretroviral therapy (ART) adherence is crucial for virological suppression and positive treatment outcomes among people living with HIV (PLHIV), but remains a challenge in ensuring patients achieve and sustain viral load suppression. Despite the recommended use of digital tools medications uptake reminders, the contribution of forgetting to take medication is unknown. This study investigated the contribution of forgetting to take medication on the total missed medication and its effects on detectable viral load (VL). Methods This mixed-method research was conducted among children, adolescents, pregnant, and breastfeeding women living with HIV on ART in northern Tanzania. Forgetting to take medication constituted reporting to have missed medication due to forgetfulness. A multivariable logistic regression model was used to estimate the adjusted odds ratio (AOR) with a 95% confidence interval (CI) to determine the contribution of forgetting medication intakes on total missed medication and other factors associated with having a detectable VL. Results Of 427 respondents, 33.3% were children, 33.4% adolescents, and 33.3% pregnant and breastfeeding women, whose median age (interquartile range) was 9 (7-12), 18 (16-18), and 31 (27-36) years, respectively. Ninety-two (22.3%) reported missing medication over the past month, of which 72 (17.9%) was due to forgetting. Forgetting to take medication (AOR: 1.75 95% CI: 1.01-3.06) and being on second-line regimen (AOR: 2.89 95% CI: 1.50-5.55) increased the chances of a detectable VL, while females had lower chances of detectable VL (AOR: 0.62 95% CI: 0.41-0.98). The themes on the reasons for forgetting to take medication from qualitative results included being busy with work and the importance of reminders. Conclusion Forgetting to take medication is common among PLHIV and an important predictor of a detectable VL. This calls for the use of automated short message services (SMS) reminders or Digital Adherence Tools with reminders to improve and promote good ART adherence among PLHIV.

Epidemiology of alcohol use and alcohol use disorders among people living with HIV on antiretroviral therapy in Northwest Tanzania: implications for ART adherence and case management. AIDS Care 2024; 36:652-660. [PMID: 38295268 DOI: 10.1080/09540121.2023.2299324] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Accepted: 12/18/2023] [Indexed: 02/02/2024]
Abstract
Alcohol use disorders (AUD) among people living with HIV (PLHIV) are associated with poor health outcomes. This cross-sectional study examined current alcohol use and AUD among 300 PLHIV on ART at four HIV care centres in Northwest Tanzania. Participants' data were collected using questionnaires. Alcohol use was assessed using Alcohol Use Disorders Identification Test (AUDIT). Logistic regression was used to examine associations between each outcome (current drinking and AUD) and sociodemographic and clinical factors. Association between alcohol use and ART adherence was also studied. The median age of participants was 43 years (IQR 19-71) and 41.3% were male. Twenty-two (7.3%) participants failed to take ART at least once in the last seven days. The prevalence of current drinking was 29.3% (95% CI 24.2-34.8%) and that of AUD was 11.3% (8.2%-15.5%). Males had higher odds of alcohol use (OR 3.03, 95% CI 1.79-5.14) and AUD (3.89, 1.76-8.60). Alcohol use was associated with ART non-adherence (OR = 2.78, 1.10-7.04). There was a trend towards an association between AUD and non-adherence (OR = 2.91, 0.92-9.21). Alcohol use and AUD were common among PLHIV and showed evidence of associations with ART non-adherence. Screening patients for alcohol use and AUD in HIV clinics may increase ART adherence.

Virological and care outcomes of community ART distribution: Experience with the PODI+ model in Kinshasa, Democratic Republic of the Congo. PLOS GLOBAL PUBLIC HEALTH 2024; 4:e0002343. [PMID: 38295044 PMCID: PMC10830041 DOI: 10.1371/journal.pgph.0002343] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Accepted: 12/12/2023] [Indexed: 02/02/2024]
Abstract
INTRODUCTION Differentiated service delivery models for HIV treatment can minimize unnecessary burdens on health systems and promote efficient delivery of antiretroviral therapy (ART). Under the PODI+ (poste de distribution communautaire) model, ART multi-month dispensation (MMD) was provided by lay workers (peers) in communities. We compared outcomes among clinically stable adults living with HIV receiving MMD via PODI+ or health facility (HF). METHODS Clients receiving MMD at nine HFs and two PODI+ sites in Kinshasa were followed prospectively for one year (2018-2020). Medication possession ratio (MPR) was measured as proportion of total days with medication during the study through record abstraction at 3-month intervals. Viral load was assessed at enrollment and 12 months. We compared MPR and viral load suppression by arm and examined associations and potential confounders using unadjusted and adjusted odds ratios (AOR). Likert-style client satisfaction was collected during 12-month interviews and described by arm. RESULTS Odds of maintaining viral load suppression at 12 months for PODI+ participants were two times that for HF participants. In adjusted models, PODI+ participants had 1.89 times the odds of being suppressed at 12 months compared to HF participants (95% CI: 1.10, 3.27). No significant differences in MPR were found between groups (OR: 0.86, 0.38-1.99). Older participants had significantly higher odds of MPR (AOR: 1.02, 95% CI: 1.01, 1.03) and viral suppression (AOR: 1.03, 95% CI: 1.00, 1.07). Satisfaction with services was ≥87% overall, but PODI+ participants rated time spent at site, provider attributes and other care aspects more favorably. CONCLUSIONS Participants receiving MMD via peer-run community distribution points had similar MPR, but better virological outcomes and greater satisfaction with care than clinically similar participants receiving MMD through facilities. PODI+ could be a useful model for expansion to serve larger clinic populations from overburdened health facilities, particularly as policy shifts towards more inclusive MMD eligibility requirements.

High viral suppression and detection of dolutegravir-resistance associated mutations in treatment-experienced Tanzanian adults living with HIV-1 in Dar es Salaam. Sci Rep 2023; 13:20493. [PMID: 37993493 PMCID: PMC10665358 DOI: 10.1038/s41598-023-47795-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Accepted: 11/18/2023] [Indexed: 11/24/2023] Open
Abstract
To curb HIV infection rate in Tanzania, antiretroviral therapy (ART) has been scaled up since 2006, and in 2019, the country shifted to regimen including dolutegravir as a default first line. We assessed the success of ART and the contribution of HIV drug resistance (HIVDR) to unsuppressed viral loads. Between February and May 2023 a cross-sectional survey with random sampling was conducted in the six clinics in an urban cohort in Dar es Salaam. Patients with unsuppresed viral loads (local criteria viral load (VL) ≥ 1000 copies/mL) were tested for HIVDR mutations using the WHO adapted protocol for plasma samples. Mutations were interpreted using the Stanford HIVDR database. In total 600 individuals participated in this survey, the majority were female (76.83%), mean age ([Formula: see text] standard deviation) was 44.0 ([Formula: see text] 11.6) years. The median duration on ART (interquartile range) was 6.5 (3.9-10.2) years. Approximately 99% were receiving tenofovir + lamivudine + dolutegravir as a fixed dose combination. VL testing was successful in 99.67% (598/600) of survey patients and only 33 had VL ≥ 1000 copies/mL, resulting in a viral suppression level of 94.48% (565/598, 95% CI 92.34-96.17%). For 23 samples, protease and reverse transcriptase (RT) genotyping were successful, with 13 sequences containing RT inhibitor surveillance drug resistance mutations (SDRMs) (56.5%). No SDRM against protease inhibitors were detected. Thirty samples were successfully genotyped for integrase with 3 sequences (10.08%) containing integrase strand transfer inhibitor (INSTI) SDRMs. In samples successfully genotyped in the three genetic regions, 68.18% (16/22) had a genotypic susceptibility score (GSS) ≥ 2.5 for the concurrent regimen, implying factors beyond drug resistance caused the unsuppressed viral load. For five patients, GSS indicated that HIVDR may have caused the unsuppressed viral load. All three patients with INSTI resistance mutations were highly resistant to dolutegravir and accumulated nucleoside and non-nucleoside RT inhibitor HIVDR mutations. Although in this cohort the last 95 UNAIDS target was almost achieved, HIVDR mutations, including INSTIs resistance mutations were detected in HIV-positive individuals taking ART for at least one year. We recommend the design and implementation of high-impact interventions to prevent the increase of HIVDR, failure of dolutegravir and address the non-resistance factors in the study area.

Factors associated with adherence to antiretroviral therapy in HIV-infected subjects and the use of indicators to characterize the treatment adhesion profile. Braz J Med Biol Res 2023; 56:e12738.

Abstract
At present, there is no gold standard to assess patient adherence to combination antiretroviral therapy (cART). Therefore, this study aimed to characterize the epidemiological profile, delineate adherence indicators, and identify factors associated with adherence and delays in obtaining medication in patients registered at the Specialized Assistance Service in HIV/AIDS in Brazil. This is a descriptive study based on secondary data obtained from official databases of the Brazilian Ministry of Health. Adherence and delay were measured by the frequency of cART medication acquisition in 24 months, and a multivariate linear regression model was developed to identify the factors associated with non-adherence and delays. In 50.2% of the subjects, the viral load remained undetectable throughout the study period. Only 12.4% of patients were fully adherent to cART. Regarding indicators, a value of 0.83 was found for adherence, 0.09 for delay in days, and 0.21 for the number of times the patient was late to obtain the medication. The multivariate analysis showed that males, age between 20 and 59 years, having not changed the cART, and the presence of ≥1000 HIV RNA copies/mL were predictive factors for adherence and delays (P≤0.01). We demonstrated that monitoring cART medication distribution is possible using health indicators, and identifying the factors associated with poor adherence to cART helps characterize patients at higher risks of unsuccessful therapy.

Pan Afr Med J 2023; 46:74. [PMID: 38282767 PMCID: PMC10819837 DOI: 10.11604/pamj.2023.46.74.40122] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Accepted: 09/10/2023] [Indexed: 01/30/2024] Open
Abstract
Introduction sub-Saharan Africa, home to over 10% of the world´s population, is the worst Human Immunodeficiency Virus (HIV)-affected region in the world. HIV/AIDS is a major public health challenge in Lesotho, with an HIV prevalence of 25.6% in 2018. The aim of this study was to evaluate the treatment outcomes of people living with HIV (PLHIV) on antiretroviral therapy (ART) after 48 months of initiation. Methods we conducted a register-based retrospective cohort study for all patients registered at the Senkatana ART Clinic from January to December 2014 and followed them for 48 months until 2018. The ART treatment register and treatment cards were the primary source of data. Data were captured and cleaned in Epi info version 7 and exported into Stata version 14 for analysis. Descriptive statistics were used to describe participant characteristics. Due to the lack of incident data, the factors associated with treatment outcomes were determined using Chi-square tests and logistic regression. Results in 2014, 604 patients were enrolled on ART, of which the majority were female (59.4%) and married (54.8%). The mean age (standard deviation (SD)) at which ART was started was 36 years (10.5) years. After 48 months of initiation, the cohort consisted of 387 patients of which 365 (94.3%) were retained on treatment. In the multivariable logistic regression model, neither demographic characteristics nor clinical factors were associated with ART treatment outcome (viral load suppression, adherence, or ART retention), however, the univariable analysis showed that higher CD4 count at initiation was associated with viral load suppression. Conclusion retention, viral load suppression, and adherence were generally good in this cohort after 48 months of initiation. CD4 at initiation was a significant predictor of viral load suppression at 48 months. The ART programme has managed to maintain high viral load suppression and improve immunity in patients who are immunocompromised. Proper data quality management is required for adequate patient monitoring to enable clinical personnel to record and use individual patient data for guiding the clinical management of such patients. Strengthening patient support and tracing will help to reduce the number of patients lost to follow-up.

Predicting viral load suppression by self-reported adherence, pharmacy refill counts and real time medication monitoring among people living with HIV in Tanzania. AIDS Res Ther 2022; 19:51. [PMCID: PMC9664713 DOI: 10.1186/s12981-022-00475-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2022] [Accepted: 10/07/2022] [Indexed: 11/16/2022] Open

Abstract
Introduction
Monitoring of adherence to antiretroviral treatment (ART) is of utmost importance to prevent treatment failure. Several measures to monitor adherence have been applied in low-resource settings and they all have pros and cons. Our objective was to examine whether any of the following adherence measures is a better predictor of participants’ viral load suppression: (1) self-report, (2) pharmacy refill count, (3) Real Time Medication Monitoring (RTMM), (4) a combination of self-report and pharmacy refill count or (5) all three adherence assessment methods combined.
Methodology
This was a post-hoc analysis of data from our 48-week REMIND-HIV randomized controlled trial in which adherence to ART was measured using self-report, pharmacy refill counts and RTMM among ART-experienced adults living with HIV subjectively judged to be nonadherent to ART. For each adherence measure, we calculated sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for predicting virological failure defined as a viral load (VL) of > 20 copies/mL. To determine at which percentage of adherence the prediction was strongest, we evaluated adherence cut-offs of 80%, 85%, 90%, 95% and 100% using receiver operating characteristic (ROC) curves. VL data were obtained after 48 weeks of follow-up in the trial.
Results
A total of 233 people living with HIV (PLHIV) were included in this analysis. When comparing the ability of self-reported adherence with pharmacy refill count and RTMM adherence to predict viral load > 20 copies/ml, self-reported adherence had the lowest sensitivity, ranging from 6 to 17%, but the highest specificity, ranging from 100 to 86%, depending on cut-off values from 80 to 100%. Area under the ROC curves (AUC) were 0.54 for RTMM, 0.56 for pharmacy refill count and 0.52 for self-report, indicating low discriminatory capacity for each of the adherence measures. When we combined the self-report and pharmacy refill count measures, sensitivity increased, ranging from 28 to 57% but specificity decreased, ranging from 83 to 53%. When all three measures were combined, we observed the highest value of sensitivity, ranging from 46 to 92%, and PPV, ranging from 32 to 36%, at high cut-offs ranging from 80 to 100%. Upon combination of three adherence measures, the AUC increased to 0.59.
Conclusion
Our results show that adherence assessed exclusively by self-report, pharmacy refill count or RTMM were insufficiently sensitive to predict virologic failure. Sensitivity markedly improved by combining all three measures, but the practical feasibility of such an approach would need to be studied.

Abstract
Background Adherence to antiretroviral therapy (ART) among key populations like human immunodeficiency virus (HIV)-positive People Who Inject Drugs (PWID) could be challenging, especially in low and middle-income countries (LMICs). Therefore we conducted this study to assess the adherence to ART among HIV-positive PWID attending three methadone clinics in Dar es Salaam, Tanzania. Methods A cross-sectional study was conducted at three methadone clinics in Dar es Salaam, Tanzania. Adherence to ART was measured by using pharmacy refill and patient self-report methods. Bivariate and multivariable logistic regression was performed to determine the association between dependent and independent variables. A p-value of less than 0.05 was considered to be statistically significant. Results Of the 180 participants, 97.2% recorded good adherence to ART as per the pharmacy refill method. However, only 66.1% of the PWID were found to adhere to ART based on the patient self-report method. Upon associating the self-report method with a viral load of >1000 copies/mL, participants were 3.37 times more likely to have missed their ART dose at least once in the last three days before their refill visit compared to those with a viral load of <1000 copies/mL [Adjusted Odds ratio; 3.37, 95% Confidence Interval (95% CI); 1.35 - 8.45, p = 0.009]. Conclusion The adherence to ART among HIV-infected PWID attending methadone clinics was high based on the pharmacy refill method but relatively much lower based on the patient self-report method. There was a strong correlation between viral load and the level of adherence measured by the patient self-report method.

Adherence to Antiretroviral Therapy by Medication Possession Ratio and Virological Suppression among Adolescents and Young Adults Living with HIV in Dar es Salaam, Tanzania. Trop Med Infect Dis 2022; 7:tropicalmed7040052. [PMID: 35448827 PMCID: PMC9028327 DOI: 10.3390/tropicalmed7040052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Revised: 02/28/2022] [Accepted: 03/04/2022] [Indexed: 02/01/2023] Open
Abstract
Background: Adherence to antiretroviral therapy (ART) is a strong determinant of virological suppression. We aimed to determine the magnitude of adherence as measured by medication possession ratio (MPR) and virological suppression with its predictors among adolescents and young adults (AYA) living with HIV on ART in Tanzania. Methods: This retrospective cohort study was conducted using archived data from HIV care and treatment centers in Dar es Salaam, Tanzania between 2015 and 2019. The logistic regression model assessed predictors for adherence and virological suppression. Results: Data of 5750 AYA living with HIV were analysed. The majority were females: 4748 (82.6%). About 63% had good adherence with MPR ≥ 85% at one year post ART initiation. Independent predictors of ART adherence were male sex (aOR = 1.3, 95% CI 1.1−1.5), CD4 > 500 cells/mm3 (aOR = 0.7, 95% CI: 0.6−0.9), WHO stage III (aOR = 1.6, 95% CI 1.3−1.9), enrollment in 2019 (aOR = 1.5, 95% CI 1.2−1.9), and virological suppression (aOR = 2.0, 95% CI 1.6−2.9). Using an Efavirenz- and a Nevirapine-based combination was associated with reduced odds of ART adherence (aOR = 0.3, 95% CI 0.1−0.8) and (aOR = 0.2, 95% CI 0.1−0.6), respectively. Predictors of virological suppression were MPR ≥ 85% (aOR = 2.0, 95% CI 1.6−2.4); CD4 > 500 cells/mm3 (aOR = 2.4, 95% CI 1.7−3.4), and once-daily dosing (aOR = 2.0, 95% CI 1.3−2.5). Conclusion: Adherence to ART among AYA living with HIV is suboptimal. Sex, year of enrollment, ART drug combination used, and immunological status at ART initiation are important predictors of adherence to ART and virological suppression.

Abstract
Background: Adherence to antiretroviral therapy (ART) is the key determinant of virological suppression in people living with HIV (PLHIV). This study reports factors associated with non-adherence among PLHIV one year after introducing dolutegravir (DTG) based regimens in Tanzania. Methods: A hospital-based cross-sectional study was conducted in two health facilities in Dar es Salaam, Tanzania, in 2020. Results: A total of 406 PLHIV were recruited, where the majority (73.4%) were females, with 94.6% of patients being on DTG based regimens. Factors such as refill interval and sharing of antiretrovirals had significant effects on adherence. Multivariate analysis found that patients attending care and treatment center (CTC) at Temeke Regional Referral Hospital (RRH) were 4.3 times more likely to have non-adherence compared to those attending Amana RRH (aOR [adjusted odds ratio] 4.3, 95% CI [confidence interval]: 2.38 – 7.91, p-value < 0.0001). Conclusions: Sustainable adherence counseling is warranted to overcome non-adherence to ART.

Development of HIV Drug Resistance in a Cohort of Adults on First-Line Antiretroviral Therapy in Tanzania during the Stavudine Era. MICROBIOLOGY RESEARCH 2021.

Abstract
As more HIV patients start combination antiretroviral therapy (cART), the emergence of HIV drug resistance (HIVDR) is inevitable. This will have consequences for the transmission of HIVDR, the success of ART, and the nature and trend of the epidemic. We recruited a cohort of 223 patients starting or continuing their first-line cART in Tanzania towards the end of the stavudine era in 2010. Patients were then followed for one year. Of those with a viral load test at baseline and follow-up time, 34% had a detectable viral load at the one-year endpoint. For 41 patients, protease and reverse transcriptase genotyping were successful. Eighteen samples were from cART-naïve patients, and 23 samples were taken under therapy either at baseline for cART-experienced patients or from follow-up samples for both cART–naïve and cART–experienced patients. The isolates were subtype A, followed by C and D in 41.5%, 22%, and 12.2% of the patients, respectively. No transmitted HIVDR was detected, as scored using the surveillance drug resistance mutations (DRMs) list. However, in 3 of the 18 samples from cART-naïve patients, the clinical Rega interpretation algorithm scored 44D or 138A as non-nucleoside reverse transcriptase inhibitor (NNRTI) resistance-associated polymorphisms. The most observed nucleoside reverse transcriptase inhibitor (NRTI) mutation was 184V. The mutation was found in 16 patients, causing resistance to lamivudine and emtricitabine. Nineteen patients had NNRTI resistance mutations, the most common of which was 103N, observed in eight patients. These high levels of resistance call for regular drug resistance surveillance in Tanzania to inform the control of the emergence and transmission of HIVDR.

Abstract
This study aimed to assess the knowledge of antiretroviral (ARV) treatment and the associated factors in HIV-infected patients in Vietnam. We conducted a cross-sectional descriptive study of 350 human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients being treated with ARV at outpatient clinics at Soc Trang, Vietnam, from June 2019 to December 2019. Using an interview questionnaire, patients who answered at least eight out of nine questions correctly, including some required questions, were considered to have a general knowledge of ARV treatment. Using multivariate logistic regression to identify factors associated with knowledge of ARV treatment, we found that 62% of HIV-infected patients had a general knowledge of ARV treatment, with a mean score of 8.2 (SD 1.4) out of 9 correct. A higher education level (p < 0.001); working away from home (p = 0.013); getting HIV transmitted by injecting drugs or from mother-to-child contact (p = 0.023); the presence of tension, anxiety, or stress (p = 0.005); self-reminding to take medication (p = 0.024); and a high self-evaluated adherence (p < 0.001) were found to be significantly associated with an adequate knowledge of ARV treatment. In conclusion, education programs for patients, as well as the quality of medical services and support, should be strengthened.

Abstract
OBJECTIVE To investigate completion of referral among women with suspected cervical cancer in Tanzania. METHODS Retrospective cohort study of 196 women referred from two healthcare clinics to Ocean Road Cancer Institute, Dar es Salaam, between March 2016 and June 2018. Women with precancerous lesions or suspected cancer were interviewed about their knowledge and perception of cervical cancer and referred for follow-up. RESULTS Most participants were unable to name symptoms (55.1%), prevention methods (88.3%), or treatments (59.0%), although 79.1% rated the disease as severe. Women who came for routine early detection were less likely to complete referral than those who did not (odds ratio [OR], 0.18; 95% confidence interval [CI], 0.05-0.70). Women who knew someone who died from cervical cancer were 5.40 times more likely to complete referral than those who did not. Knowing someone with cervical cancer was a predictor of referral completion in three multivariate models: OR, 5.62 (95% CI, 2.20-14.38); 4.34 (1.64-11.47); and 4.61 (1.72-12.36). Having severe symptoms was a predictor of non-completion in two models: 0.30 (0.12-0.75) and 0.35 (0.14-0.87). CONCLUSION Patient-directed interventions should include education involving survivors of cancer and dysplasia, whereas system-directed interventions should utilize reminders to increase referral completion.

Abstract
Antiretroviral therapy (ART) is efficacious in improving clinical outcomes among people living with HIV (PLWH) and reducing HIV transmission when taken regularly. Research examining modifiable factors associated with ART non-adherence is critical for informing novel intervention development in settings with high HIV prevalence. Alcohol use has been linked with ART non-adherence in studies in sub-Saharan Africa; however, no review has pooled estimates across studies. We reviewed studies of alcohol use and ART non-adherence conducted in sub-Saharan Africa. We searched PubMed, CINAHL, EMBASE, and PsycINFO through August 2019 with terms related to ART non-adherence, alcohol use, and sub-Saharan Africa. One author reviewed titles/abstracts (n = 754) and two authors reviewed full texts (n = 308) for inclusion. Discrepancies were resolved by group consensus. Studies were retained if they quantitatively measured associations between alcohol use and ART non-adherence or viral non-suppression. We defined ART non-adherence using the definitions from each parent study (e.g., patients with > 5% missed ART doses during the previous four, seven or 30 days were considered non-adherent). A random effects meta-analysis was conducted to pool associations and we conducted additional analyses to assess between-study heterogeneity and publication bias and sensitivity analyses to determine robustness of our results when considering only certain study designs, alcohol use or ART scales, or studies that used viral non-suppression as their primary outcome. Of 56 articles meeting our inclusion criteria, 32 articles were included in the meta-analysis. All studies measured alcohol use via self-report. ART non-adherence was assessed using self-report, pill counts, or pharmacy records and definition of non-adherence varied depending on the measure used. Individuals who used alcohol had twice the odds of ART non-adherence compared with those who did not use alcohol (34% non-adherence among alcohol users vs. 18% among non-users; pooled odds ratio: 2.25; 95% confidence interval: 1.87-2.69; p < 0.001). We found evidence of a high degree of heterogeneity between studies (Cochrane Q statistic: 382.84, p< 0.001; I2 proportion: 91.9%) and evidence of publication bias. However, the magnitude of our pooled odds ratio was consistent across a number of sensitivity analyses to account for heterogeneity and publication bias. In a secondary analysis with studies using viral non-suppression as their primary outcome, we also estimated a statistically significant pooled effect of alcohol use on viral non-suppression (pooled odds ratio: 2.47; 95% confidence interval: 1.58-3.87). Evidence suggests alcohol use is associated with ART non-adherence in Sub-Saharan Africa, potentially hindering achievement of the UNAIDS 90-90-90 HIV treatment targets.

Abstract
Background Nonadherence to antiretroviral therapy (ART) among people with HIV/AIDS can lead to drug resistance and death. Different studies have defined nonadherence, and it denotes at least one missed dose of ART within 28 days. One of the strategies to prevent nonadherence to ART could be peer education. However, published studies which test out whether or not peer education is effective for prevention of nonadherence to ART among adults living with HIV were not available. Moreover, published studies on factors discussing the success of peer education against nonadherence to ART were not available, so we conducted this study. Objectives To determine effectiveness of peer education against nonadherence to ART and identify factors influencing the effectiveness of peer education for prevention of nonadherence to ART among people living with HIV/AIDS in Arsi zone, Ethiopia. Methods An institution based pre-post intervention study was conducted. The intervention was giving peer education for three months. Frequencies and percentages were used to describe the data. Binary and multivariate logistic regressions were used to assess the variables. Results The data was collected from 355 and 319 people with HIV/AIDS at pre- and post-intervention stages, respectively. Experiencing an ART side effect, reminder to take ART, gender, marital status and monthly income were associated with nonadherence. More study participants who had not useda reminder to take ART service missed at least one dose of ART when compared to those who used a reminder to take ART service (adjusted odds ratio (AOR) =6.21; 95% CI=2.12–18.20). Conclusion Experiencing a side effect of ART influenced effectiveness of peer education negatively while using reminder to take ART influenced effectiveness positively. Peer education is effective for reduction of nonadherence to ART if it is used with reminder to take ART. This study can be a base for further studies that should be conducted in various areas, since peer education can be influenced by sociodemographic and economic factors.

Abstract
The introduction of antiretroviral therapy (ART) has helped HIV population to live longer, but they could face not only AIDS-related morbidity but also other non-communicable diseases. Paying attention to ART adherence requires a system thinking with the life-long factors, individual-environment interactions and contextualized dynamics. Although several quantitative research had been conducted, they were not able to fully demonstrate the development of research approaches and scopes of previous studies. Essential and practical public health policy should be based on the most accessible and strategically analyzed evidence. Therefore, our study uses a scientometric approach to supplement previous reviews research covering until the end of 2017. Using a combination of two quantitative approaches to supplement previous reviews, we attempt to identify the research trends and potential research gaps which could be very helpful for policies and practices enhancements to inform evidence-based strategies. Our result indicates countries tend to collaborate in traditional models rather than prioritize severity and characteristics of HIV epidemics. Further ART research should highlight the incorporation of newly developed technology to examine long-term impacts, combine multiple measures, address contextual factors, and involve available technologies and resources, e.g., family, community.
