Afr J Lab Med 2024 13 (1) 2259 BACKGROUND: Standardising procedures is the best way to harmonise and strengthen the quality of laboratory-based antimicrobial resistance surveillance. Since 2018, Burkina Faso has developed and disseminated the national manual of procedures for performing antibiotic susceptibility tests in sentinel laboratories within its national antimicrobial resistance surveillance network. OBJECTIVE: Our study aimed to assess these sentinel laboratories' compliance with good practices for antibiotics susceptibility tests. METHODS: Four teams evaluated the antimicrobial resistance sentinel sites laboratories throughout Burkina Faso from 19 to 28 September 2022. Eighteen out of 19 sentinel laboratories were evaluated. A four-member technical committee designed and validated the evaluation tool composed of three Microsoft Excel sheets. The evaluation emphasised quality controls for culture media, antibiotic discs and compliance with antimicrobial susceptibility testing procedures by the laboratories. Excel software was used for data recording and graphs and table design. The free R software version 4.2.0 was used for descriptive statistics. An overall score below 80% was considered noncompliance. RESULTS: Most (83.33%) of the sentinel laboratories conducted at least one quality control activity for culture media, and 66.67% conducted at least one quality control activity for antibiotic discs. Over three-quarters (76.47%) of the laboratories were more than 80% compliant with the modified Kirby Bauer antimicrobial susceptibility testing method. CONCLUSION: The evaluation revealed the noncompliance of sentinel laboratories with the national procedure manual, particularly in the quality control component. WHAT THIS STUDY ADDS: This study has provided baseline data on the sentinel laboratories' compliance with the national antimicrobial susceptibility testing procedures manual, particularly in areas performing quality control checks or meeting quality indicators for culture media and antibiotic discs. |
On-site evaluation as external quality assessment of microbiology laboratories involved in sentinel laboratory-based antimicrobial resistance surveillance network in Burkina Faso
Zongo E , Dama E , Yenyetou D , Muhigwa M , Nikiema A , Dahourou GA , Ouedraogo AS . Antimicrob Resist Infect Control 2024 13 (1) 3 BACKGROUND: The laboratory-based surveillance of antimicrobial resistance (AMR) is a priority component of the multisectoral national action plan to combat AMR in Burkina Faso. This study aimed to assess the QMS of microbiology laboratories involved in the Sentinel laboratory-based antimicrobial resistance surveillance network in Burkina Faso. METHODS: A cross-sectional study was conducted from September 1st to November 30(th,) 2022. The external quality assessment (EQA) method used was on-site evaluation using a checklist that was developed and validated by a technical committee of experts. Teams of two, including an antimicrobial susceptibility test (AST) specialist and a QMS specialist, were trained on this checklist to conduct the assessment. Satisfactory performance was defined as any on-site evaluation score 80% and above with the aim of developing action plans to address gaps. RESULTS: All 18 laboratories were evaluated. The overall average performance score of the participating laboratories was 40%. The highest overall performance score was 58%, and the lowest overall performance score was 26%. The average overall scores were not significantly different between private and public laboratories (p value = 0.78). The only section of the checklist with the satisfactory performance concerned the "Analytical step of AST", with 76.5% (13/17) of the sentinel laboratories having a score ≥ 80%. CONCLUSION: The performance of the QMS of the sentinel laboratories in Burkina Faso for AMR surveillance was unsatisfactory, and a corrective action plan was proposed to support these laboratories in improving their QMS over the next 3 years. |
Designing and piloting a specimen transport system in Burkina Faso

Health Secur 2020 18 S98-s104 Efficient specimen transport systems are critical for early disease detection and reporting by laboratory networks. In Burkina Faso, centralized reference laboratories receive specimens from multiple surveillance sites for testing, but transport methods vary, resulting in potential delays and risk to specimen quality. The ministry of health and partners, under the Global Health Security Agenda implementation, piloted a specimen transport system for severe acute respiratory illness (SARI) surveillance in 4 Burkina Faso districts. A baseline assessment was conducted of the current specimen transport network structure and key stakeholders. Assessment results and guidelines for processing SARI specimens informed the pilot specimen transport system design and implementation. Monitoring and evaluation performance indicators included: proportion of packages delivered, timeliness, and quality of courier services (missed or damaged packages). Our baseline assessment found that laboratorians routinely carried specimens from the health center to reference laboratories, resulting in time away from laboratory duties and potential specimen delays or loss of quality. The pilot specimen transport system design engaged Sonapost, the national postal service, to transport specimens from SARI sites to the influenza national reference laboratory. From May 2017 to December 2018, the specimen transport system transported 557 packages containing 1,158 SARI specimens; 95% (529/557) were delivered within 24 hours of pick-up and 77% (892/1,158) within 48 hours of collection. No packages were lost. This article highlights lessons learned that may be useful for other countries considering establishment of a specimen transport system to strengthen laboratory system infrastructure in global health security implementation. |
Building laboratory-based arbovirus sentinel surveillance capacity during an ongoing dengue outbreak, Burkina Faso, 2017

Health Secur 2018 16 S103-s110 In West Africa, identification of nonmalarial acute febrile illness (AFI) etiologic pathogens is challenging, given limited epidemiologic surveillance and laboratory testing, including for AFI caused by arboviruses. Consequently, public health action to prevent, detect, and respond to outbreaks is constrained, as experienced during dengue outbreaks in several African countries. We describe the successful implementation of laboratory-based arbovirus sentinel surveillance during a dengue outbreak in Burkina Faso during fall 2017. We describe implementation, surveillance methods, and associated costs of enhanced surveillance during an outbreak response as an effort to build capacity to better understand the burden of disease caused by arboviruses in Burkina Faso. The system improved on existing routine surveillance through an improved case report form, systematic testing of specimens, and linking patient information with laboratory results through a data management system. Lessons learned will improve arbovirus surveillance in Burkina Faso and will contribute to enhancing global health security in the region. Elements critical to the success of this intervention include responding to a specific and urgent request by the government of Burkina Faso and building on existing systems and infrastructure already supported by CDC's global health security program. |

Environ Health Perspect 2012 120 (10) 1450-5 BACKGROUND: During May-June 2010, a childhood lead poisoning outbreak related to gold-ore-processing was confirmed in 2 villages in Zamfara State, Nigeria. During June-September, villages with suspected or confirmed childhood lead poisoning continued to be identified in Zamfara State. OBJECTIVES: We investigated the extent of childhood lead poisoning (≥1 child with a blood lead level [BLL] ≥10 microg/dL) and lead contamination (≥1 soil/dust sample with a lead level >400 parts per million) among villages in Zamfara State and identified villages that should be prioritized for urgent interventions. METHODS: We used chain-referral sampling to identify villages of interest, defined as villages suspected of participation in gold-ore-processing during the previous 12 months. We interviewed villagers, determined BLLs among children aged <5 years, and analyzed soil/dust from public areas and homes for lead. RESULTS: We identified 131 villages of interest and visited 74 (56%) villages in 3 local government areas. Fifty-four (77%) of 70 villages that completed the survey reported gold-ore-processing. Ore-processing villages were more likely to have ≥1 child aged <5 years with lead poisoning (68% vs. 50%, p=0.17) or death following convulsions (74% vs. 44%, p=0.02). Soil/dust contamination and BLL ≥45 microg/dL were identified in ore-processing villages only [50% (p<0.001) and 15% (p=0.22), respectively]. The odds of childhood lead poisoning or lead contamination was 3.5 times as high in ore-processing villages than the other villages (95% CI: 1.1, 11.3). CONCLUSION: Childhood lead poisoning and lead contamination were widespread in surveyed areas, particularly among villages that had processed ore recently. Urgent interventions are required to reduce lead exposure, morbidity, and mortality in affected communities. |
