Annual home-based HIV testing in the Chókwè Health Demographic Surveillance System, Mozambique, 2014 to 2019: serial population-based survey evaluation.

INTRODUCTION: WHO recommends implementing a mix of community and facility testing strategies to diagnose 95% of persons living with HIV (PLHIV). In Mozambique, a country with an estimated 506,000 undiagnosed PLHIV, use of home-based HIV testing services (HBHTS) to help achieve the 95% target has not been evaluated. METHODS: HBHTS was provided at 20,000 households in the Chókwè Health Demographic Surveillance System (CHDSS), Mozambique, in annual rounds (R) during 2014 to 2019. Trends in prevalence of HIV infection, prior HIV diagnosis among PLHIV (diagnostic coverage), and undiagnosed HIV infection were assessed with three population-based surveys conducted in R1 (04/2014 to 04/2015), R3 (03/2016 to 12/2016), and R5 (04/2018 to 03/2019) of residents aged 15 to 59 years. Counts of patients aged ≥15 years tested for HIV in CHDSS healthcare facilities were obtained from routine reports. RESULTS: During 2014 to 2019, counsellors conducted 92,512 home-based HIV tests and newly diagnosed 3711 residents aged 15 to 59 years. Prevalence of HIV infection was stable (R1, 25.1%; R3 23.6%; R5 22.9%; p-value, 0.19). After the first two rounds (44,825 home-based tests; 31,717 facility-based tests), diagnostic coverage increased from 73.8% (95% CI 70.3 to 77.2) in R1 to 93.0% (95% CI 91.3 to 94.7) in R3, and prevalence of undiagnosed HIV infection decreased from 6.6% (95% CI 5.6 to 7.5) in R1 to 1.7% (95% CI 1.2 to 2.1) in R3. After two more rounds (32,226 home-based tests; 46,003 facility-based tests), diagnostic coverage was 95.4% (95% CI 93.7 to 97.1) and prevalence of undiagnosed HIV infection was 1.1% (95% CI 0.7 to 1.5) in R5. Prevalence of having last tested at home was 12.7% (95% CI 11.3 to 14.0) in R1, 45.2% (95% CI 43.4 to 47.0) in R3, and 41.4% (95% CI 39.5 to 43.2) in R5, and prevalence of having last tested at a healthcare facility was 45.3% (95% CI 43.3 to 47.3) in R1, 40.1% (95% CI 38.4 to 41.8) in R3, and 45.2% (95% CI 43.3 to 47.0) in R5. CONCLUSIONS: HBHTS successfully augmented facility-based testing to achieve HIV diagnostic coverage in a high-burden community of Mozambique. HBHTS should be considered in sub-Saharan Africa communities striving to diagnose 95% of persons living with HIV.

Prevalence of Voluntary Medical Male Circumcision for HIV Infection Prevention - Chókwè District, Mozambique, 2014-2019.

Male circumcision is an important preventive strategy that confers lifelong partial protection (approximately 60% reduced risk) against heterosexually acquired HIV infection among males (1). In Mozambique, the prevalence of male circumcision was 51% when the voluntary medical male circumcision (VMMC) program began in 2009. The Mozambique Ministry of Health set a goal of 80% circumcision prevalence among males aged 10-49 years by 2019 (2). CDC analyzed data from five cross-sectional surveys of the Chókwè Health and Demographic Surveillance System (CHDSS) to evaluate progress toward the goal and guide ongoing needs for VMMC in Mozambique. During 2014-2019, circumcision prevalence among males aged 15-59 years increased 42%, from 50.1% to 73.5% (adjusted prevalence ratio [aPR] = 1.42). By 2019, circumcision prevalence among males aged 15-24 years was 90.2%, exceeding the national goal (2). However, circumcision prevalence among males in older age groups remained below 80%; prevalence was 62.7%, 54.5%, and 55.7% among males aged 25-34, 35-44, and 45-59 years, respectively. A multifaceted strategy addressing concerns about the safety of the procedure, cultural norms, and competing priorities that lead to lack of time could help overcome barriers to circumcision among males aged ≥25 years.

A randomized, double-blind, phase 2b study to investigate the efficacy, safety, tolerability and pharmacokinetics of a single-dose regimen of ferroquine with artefenomel in adults and children with uncomplicated Plasmodium falciparum malaria.

BACKGROUND: For uncomplicated Plasmodium falciparum malaria, highly efficacious single-dose treatments are expected to increase compliance and improve treatment outcomes, and thereby may slow the development of resistance. The efficacy and safety of a single-dose combination of artefenomel (800 mg) plus ferroquine (400/600/900/1200 mg doses) for the treatment of uncomplicated P. falciparum malaria were evaluated in Africa (focusing on children ≤ 5 years) and Asia. METHODS: The study was a randomized, double-blind, single-dose, multi-arm clinical trial in patients aged > 6 months to < 70 years, from six African countries and Vietnam. Patients were followed up for 63 days to assess treatment efficacy, safety and pharmacokinetics. The primary efficacy endpoint was the polymerase chain reaction (PCR)-adjusted adequate clinical and parasitological response (ACPR) at Day 28 in the Per-Protocol [PP] Set comprising only African patients ≤ 5 years. The exposure-response relationship for PCR-adjusted ACPR at Day 28 and prevalence of kelch-13 mutations were explored. RESULTS: A total of 373 patients were treated: 289 African patients ≤ 5 years (77.5%), 64 African patients > 5 years and 20 Asian patients. None of the treatment arms met the target efficacy criterion for PCR-adjusted ACPR at Day 28 (lower limit of 95% confidence interval [CI] > 90%). PCR-adjusted ACPR at Day 28 [95% CI] in the PP Set ranged from 78.4% [64.7; 88.7%] to 91.7% [81.6; 97.2%] for the 400 mg to 1200 mg ferroquine dose. Efficacy rates were low in Vietnamese patients, ranging from 20 to 40%. A clear relationship was found between drug exposure (artefenomel and ferroquine concentrations at Day 7) and efficacy (primary endpoint), with higher concentrations of both drugs resulting in higher efficacy. Six distinct kelch-13 mutations were detected in parasite isolates from 10/272 African patients (with 2 mutations known to be associated with artemisinin resistance) and 18/20 Asian patients (all C580Y mutation). Vomiting within 6 h of initial artefenomel administration was common (24.6%) and associated with lower drug exposures. CONCLUSION: The efficacy of artefenomel/ferroquine combination was suboptimal in African children aged ≤ 5 years, the population of interest, and vomiting most likely had a negative impact on efficacy.

High Coverage of Antiretroviral Treatment With Annual Home-Based HIV Testing, Follow-up Linkage Services, and Implementation of Test and Start: Findings From the Chókwè Health Demographic Surveillance System, Mozambique, 2014-2019.

BACKGROUND: Early antiretroviral therapy (ART) is necessary for HIV epidemic control and depends on early diagnosis and successful linkage to care. Since 2014, annual household-based HIV testing and counseling and linkage services have been provided through the Chókwè Health and Demographic Surveillance System for residents testing HIV positive in this high HIV-burden district. METHODS: District-wide Test and Start [T&S, ART for all people living with HIV (PLHIV)] began in August 2016, supported by systematic interventions to improve linkage to care and treatment. Annual rounds (R) of random household surveys were conducted to assess trends in population prevalence of ART use and viral load suppression (<1000 viral RNA copies/mL). RESULTS: Between R1 (April 2014-April 2015) and R5 (April 2018-Mar 2019), 46,090 (67.2%) of 68,620 residents aged 15-59 years were tested for HIV at home at least once, and 3711 were newly diagnosed with HIV and provided linkage services. Population prevalence of current ART use among PLHIV increased from 65.0% to 87.5% between R1 and R5. ART population prevalence was lowest among men aged 25-34 years (67.8%) and women aged 15-24 (78.0%), and highest among women aged 35-44 years (93.6%) and 45-59 years (93.7%) in R5. Viral load suppression prevalence increased among all PLHIV aged 15-59 years from 52.0% in R1 to 78.3% in R5. DISCUSSION: Between 2014 and 2019, Chókwè Health and Demographic Surveillance System residents surpassed the UNAIDS targets of ≥81% of PLHIV on ART and ≥73% virally suppressed. This achievement supports the combination of efforts from household-based HIV testing and counseling, support for linkage to care and treatment, and continued investments in T&S implementation.

Análise dos factores que afectam a motivação e retenção dos recursos humanos para saúde nas unidades sanitárias dos cuidados de saúde primários no distrito de chókwè, gaza, Moçambique / Analysis of the factors affecting the motivation and retention of human resources for health in primary health care units in the district of chókwè, gaza, Mozambique

Antecedentes: Motivação dos recursos humanos é importante para alcançar metas organizacionais. No sector de saúde motivação afecta satisfação dos RHS e sua retenção nos CSP. Dados dos relatórios dos SDSMAS de Chókwè apontam tendências crescentes de saídas de pessoal entre 2018 a 2019. Não existe informação sobre os motivos. Presume-se que não estejam motivados. Este estudo analisa os factores que influenciam motivação e retenção dos recursos humanos da saúde afectos nas USs de nível dos cuidados de saúde primários do distrito de Chókwè, Província de Gaza, Sul de Moçambique. Metodologia: Foi utilizado um desenho transversal quantitativo, entrevistas face a face usando um questionário estruturado. Os dados foram duplamente entrados numa interface criada em ODK collect, geridos numa base de dados em MySQL e processados em STATA-12. Resultados: são factores determinantes de motivação subsídio de antiguidade OR 0.42 (95% CI 0.25-0.70), benefícios terminais OR 3.17 (95% CI 1.6-6.26), provisão de treinamento OR 2.75 (95% CI 1.06-7.05) e sentimento de realizar de trabalho agradável OR 4.27 (95% CI 1.07-16.92). Os factores de motivação ligados a satisfação mais classificados são: consciência sobre trabalho, sentimento de fazer parte da comunidade, envolvimento na melhoria de provisão de cuidados, sentimento de realização de trabalho agradável e respeito. Conclusões: Motivação dos RHS em Chókwè é alta. Continuidade de formação, plano de saúde e férias foram os factores compensatórios mais priorizados. Porém, essas prioridades variam por cada categoria. Políticas de atração e retenção dos RHS nos CSP devem considerar o perfil dos RHS e outros incentivos não financeiros encontrados neste estudo

Background: Motivation of human resources is important for achieving organizational goals. In the health sector, motivation affects HRH satisfaction and retention in PHC. Data from the Chókwè SDSMAS annual reports point to growing trends in staff leaving their jobs between 2018 and 2019. There is no evidence for the attached reasons. It is assumed that they're demotivated. This study analyzes the factors affecting the motivation and retention of health human resources allocated in primary health care level Health Centers in Chókwè district, Gaza Province, Southern Mozambique. Method: A quantitative cross-sectional design was used, face-to-face interviews using a structured questionnaire. The data was double entered in an ODK collect interface, managed in a MySQL database and processed in STATA-12. Results: motivating factors are seniority allowance OR 0.42 (95% CI 0.25-0.70), terminal benefits OR 3.17 (95% CI 1.6-6.26), provision of training OR 2.75 (95% CI 1.06-7.05) and feeling of accomplishing pleasant work OR 4.27 (95% CI 1.07-16.92). The motivating factors related to satisfaction were the most favorably answered, being awareness of work, feeling of being part of the community, involvement in improving the provision of care, feeling of doing pleasant work and respect, the most classified. Conclusions: HRH motivation in Chókwè is high. Pursuing academic training, health insurance and holidays were the most prioritized motivating factors linked to compensation. However, these priorities vary by category. Policies for attracting and retaining HRH in PHC must consider the staff profile and other non financial incentives identified in this study.

Low and Decreasing Prevalence and Rate of False Positive HIV Diagnosis - Chókwè District, Mozambique, 2014-2017.

In 2017, rapid human immunodeficiency virus (HIV) testing services enabled the HIV diagnosis and treatment of approximately 15.3 million persons with HIV infection in sub-Saharan Africa with life-saving antiretroviral therapy (ART) (1). Although suboptimal testing practices and misdiagnoses have been reported in sub-Saharan Africa and elsewhere, trends in population burden and rate of false positive HIV diagnosis (false diagnosis) have not been reported (2,3). Understanding the population prevalence and trends of false diagnosis is fundamental for guiding rapid HIV testing policies and practices. To help address this need, CDC analyzed data from 57,655 residents aged 15-59 years in the Chókwè Health and Demographic Surveillance System (CHDSS) in Mozambique to evaluate trends in the rate (the percentage of false diagnoses among retested persons reporting a prior HIV diagnosis) and population prevalence of false diagnosis. From 2014 to 2017, the observed rate of false diagnosis in CHDSS decreased from 0.66% to 0.00% (p<0.001), and the estimated population prevalence of false diagnosis decreased from 0.08% to 0.01% (p = 0.0016). Although the prevalence and rate of false diagnosis are low and have decreased significantly in CHDSS, observed false diagnoses underscore the importance of routine HIV retesting before ART initiation and implementation of comprehensive rapid HIV test quality management systems (2,4,5).
