Background Elimination of hepatitis C virus (HCV) among people who use drugs (PWUD) remains a challenge even in countries in which HCV care is provided free of cost. We assessed whether an innovative community-based, respondent-driven sampling (RDS) survey, coupled with HCV screening and immediate treatment, could be efficient to detect and cure current PWUD with chronic HCV in a large city of Southern France. Methods At a community site with peers, PWUD (cannabis not included) were enrolled after confirmation by a urine drug test. Participants were then screened for hepatitis B virus, HCV, and human immunodeficiency virus and benefited from onsite HCV treatment evaluation and prescription. Peer support was provided during treatment, and a systematic visit was scheduled 12 weeks after the end of treatment. The cost of the intervention was estimated. Results Five hundred fifty-four participants were enrolled. Most were male (78.8%) with a median age of 39 years (interquartile range, 33–46). Cocaine (73.1%) and heroine (46.8%) were the main drugs consumed. Overall, 32.6% of PWUD (N = 181) were HCV seropositive, 49 (27.1%) of which had detectable HCV ribonucleic acid and were thus eligible for treatment. Ten of these patients had severe fibrosis. Hepatitis C virus treatment was initiated for 37 (75.5%) patients, 30 (81.1%) of whom completed their treatment and 27 (73.0%) achieved sustained viral response at week 12. The total cost was 161 euros € per screened patient and 1816€ per patient needing treatment. Conclusions A community-based RDS survey approach, involving peers, proved efficient and cost-effective to reach and cure PWUD for HCV. This innovative strategy could be key for the final step of HCV elimination. Clinical trial registration. ClinicalTrials.gov, NCT04008927.

Background The tuberculosis (TB) epidemic is not homogeneous in the general population but presents high-risk groups. People who inject drugs (PWID) are such a group. However, TB among PWID remains largely undocumented. Our goal was to assess the prevalence of TB and the risk factors associated with TB among PWID in Vietnam. Methods We implemented a cross-sectional survey among 2 community-based cohorts of human immunodeficiency virus (HIV)-positive and HIV-negative PWID in Hai Phong. Participants were screened for TB using questions on TB symptoms. Those who reported any symptom were accompanied by peers to the TB clinic for chest x-ray. If the latter was abnormal, a sputum was collected to perform an Xpert MTB/RIF test. Results A total of 885 PWID were screened for TB. For both cohorts, most PWID were male (>90.0%), with a median age of 42 years. Beside heroin injection, 52.5% of participants reported smoking methamphetamine, and 63.2% were on methadone. Among HIV-positive PWID (N = 451), 90.4% were on antiretroviral therapy and 81.6% had a viral load, Although TB is poorly described among PWID, we report a conservative estimate of TB prevalence as high as 1.7% in Hai Phong, Vietnam. Smoking methamphetamine was independently associated with TB, but not HIV, likely due to high ART coverage.

Background. Malaria-endemic countries are encouraged to increase, expedite, and standardize care based on parasite diagnosis and treat confirmed malaria using oral artemisinin-based combination therapy (ACT) or rectal artesunate plus referral when patients are unable to take oral medication. Methods. In 172 villages in 3 African countries, trained community health workers (CHWs) assessed and diagnosed children aged between 6 months and 6 years using rapid histidine-rich protein 2 (HRP2)–based diagnostic tests (RDTs). Patients coming for care who could take oral medication were treated with ACTs, and those who could not were treated with rectal artesunate and referred to hospital. The full combined intervention package lasted 12 months. Changes in access and speed of care and clinical course were determined through 1746 random household interviews before and 3199 during the intervention. Results. A total of 15 932 children were assessed: 6394 in Burkina Faso, 2148 in Nigeria, and 7390 in Uganda. Most children assessed (97.3% [15 495/15 932]) were febrile and most febrile cases (82.1% [12 725/15 495]) tested were RDT positive. Almost half of afebrile episodes (47.6% [204/429]) were RDT positive. Children eligible for rectal artesunate contributed 1.1% of episodes. The odds of using CHWs as the first point of care doubled (odds ratio [OR], 2.15; 95% confidence interval [CI], 1.9–2.4; P < .0001). RDT use changed from 3.2% to 72.9% (OR, 80.8; 95% CI, 51.2–127.3; P < .0001). The mean duration of uncomplicated episodes reduced from 3.69 ± 2.06 days to 3.47 ± 1.61 days, Degrees of freedom (df) = 2960, Student's t (t) = 3.2 (P = .0014), and mean duration of severe episodes reduced from 4.24 ± 2.26 days to 3.7 ± 1.57 days, df = 749, t = 3.8, P = .0001. There was a reduction in children with danger signs from 24.7% before to 18.1% during the intervention (OR, 0.68; 95% CI, .59–.78; P < .0001). Conclusions. Provision of diagnosis and treatment via trained CHWs increases access to diagnosis and treatment, shortens clinical episode duration, and reduces the number of severe cases. This approach, recommended by the World Health Organization, improves malaria case management. Clinical Trials Registration. ISRCTN13858170.

Background. Use of community health workers (CHWs) to increase access to diagnosis and treatment of malaria is recommended by the World Health Organization. The present article reports on training and performance of CHWs in applying these recommendations. Methods. Two hundred seventy-nine CHWs were trained for 3–5 days in Burkina Faso, Nigeria, and Uganda, and 19 were certified to diagnose and treat only uncomplicated malaria and 235 to diagnose and treat both uncomplicated and severe malaria. Almost 1 year after training, 220 CHWs were assessed using standard checklists using facility staff responses as the reference standard. Results. Training models were slightly different in the 3 countries, but the same topics were covered. The main challenges noticed were the low level of education in rural areas and the involvement of health staff in the supervision process. Overall performance was 98% (with 99% in taking history, 95% in measuring temperature, 85% for measuring respiratory rates, 98% for diagnosis, 98% for classification, and 99% for prescribing treatment). Young, single, new CHWs performed better than their older, married, more experienced counterparts. Conclusions. Training CHWs for community-based diagnosis and treatment of uncomplicated and severe malaria is possible with basic and refresher training and close supervision of CHWs’ performance.

BACKGROUND Community health workers (CHWs) are members of a community who are chosen by their communities as first-line, volunteer health workers. The time they spend providing healthcare and the value of this time are often not evaluated. Our aim was to quantify the time CHWs spent on providing healthcare before and during the implementation of an integrated program of diagnosis and treatment of febrile illness in 3 African countries. METHODS In Burkina Faso, Nigeria, and Uganda, CHWs were trained to assess and manage febrile patients in keeping with Integrated Management of Childhood Illness recommendations to use rapid diagnostic tests, artemisinin-based combination therapy, and rectal artesunate for malaria treatment. All CHWs provided healthcare only to young children usually

BACKGROUND: Community health workers (CHWs) are an important element of care provision for a wide range of conditions but their turnover rate is high. Many studies have been conducted on health workers motivation focusing on formal sector staff but not CHWs. Although CHWs are easy to recruit motivating and retaining them for service delivery is difficult. This article investigates factors influencing CHW motivation and retention in health service delivery. METHODS: Quantitative and qualitative data were collected to identify the key factors favoring motivation and retention of CHWs as well as those deterring them. We interviewed 47 25 and 134 CHWs in Burkina Faso Nigeria and Uganda respectively using a structured questionnaire. Focus group discussions (FGDs) were also conducted with CHWs community participants and facility health workers. RESULTS: Except for Burkina Faso most CHWs were female. Average age was between 38 and 41 years and most came from agricultural communities. The majority (52%-80%) judged they had a high to very high level of satisfaction but most CHWs (approximately 75%) in Burkina Faso and Uganda indicated that they would be prepared to leave the job citing income as a major reason. Community recognition and opportunities for training and supervision were major incentives in all countries but the volume of unremunerated work at a time when both malaria-positive cases and farming needs were at their peak was challenging. CONCLUSIONS: Most CHWs understood the volunteer nature of their position but desired community recognition and modest financial remuneration. CLINICAL TRIALS REGISTRATION: ISRCTN13858170.

Background The World Health Organization recommends that all malaria management be based on parasitological identification. We monitored performance of trained community health workers (CHWs) in adhering to this recommendation to restrict artemisinin-based combination therapies (ACTs) to positive rapid diagnostic test (RDT)-confirmed cases in children in 3 malaria-endemic sub-Saharan African countries. Methods In 33 villages in Burkina Faso, 45 villages in Nigeria, and 84 villages in Uganda, 265 CHWs were trained over a minimum of 3 days to diagnose malaria using RDTs (prepare, read, record results, and inform the patient about results) and treat RDT-confirmed uncomplicated malaria cases with ACTs. In Nigeria, CHWs were also taught to obtain a thick blood smear. Spent RDT kits and prepared blood slides were collected and interpreted independently in Burkina Faso and Nigeria to confirm CHWs' diagnoses. Interviews were held with 12 of 17 CHWs who prescribed ACTs for patients with RDT-negative test results, and with 16 of 29 caregivers to determine factors related to noncompliance. Results Of 12 656 patients treated with ACTs in the participating countries (5365 in Burkina Faso, 1648 in Nigeria, and 5643 in Uganda), 29 patients (8 from Burkina Faso, 17 from Nigeria, 4 from Uganda) were RDT negative. The small number of RDT-negative ACT-treated cases limits statistical analysis. Only a few CHWs were involved, and they were more likely to be traders rather than farmers (odds ratio [OR], 6.15; 95% confidence interval [CI], 2.09-18.07; P = .0004). RDT-negative children who were treated with ACTs had a significantly higher probability of residing in a village other than that of the CHW (OR, 3.85; 95% CI, 1.59-9.30; P = .0018). Parental pressure was identified in interviews with parents. Conclusions Noncompliance with results of RDT tests is relatively rare when CHWs are trained and well supervised.

Background: Community health workers (CHWs) were trained in Burkina Faso, Nigeria and Uganda to diagnose febrile children using malaria rapid diagnostic tests (RDTs), treat positive malaria cases with artemisinin combination treatment (ACTs) and those who could not take oral medicines with rectal artesunate. We quantified the impact of this intervention on private household costs for childhood febrile illness. Methods: Households with recent febrile illness in a young child in previous two weeks were selected randomly before and during the intervention and data obtained on household costs for the illness episode. Household costs included consultation fees, registration costs, user fees, diagnosis, bed, drugs, food and transport costs. Private household costs per episode before and during the intervention were compared. The intervention’s impact on household costs per episode was calculated and projected to district-wide impacts on household costs. Results: Use of CHW increased from 35% of illness episodes before the intervention to 50% during the intervention (pConclusions: Improving access to malaria diagnostics and treatments in malaria endemic areas substantially reduces private household costs. The key challenge is to develop and strengthen community human resources to deliver the intervention, and ensure adequate supplies of commodities and supervision. We demonstrate feasibility and benefit to populations living in difficult circumstances.
