Underutilization of the Clinical Microbiology Laboratory by Physicians in Nigeria
Background: Clinical laboratories are critical to correct diagnosis of medical conditions to ensure appropriate management. Point prevalence survey (PPS) of antimicrobial use and resistance performed in Nigeria in 2015 and 2017 showed high rates of antibiotic use, but poor laboratory utilization for definitive diagnosis of the infections for which the antimicrobials were prescribed. This study investigated the reasons for clinicians‟ poor utilization of the clinical laboratory for definitive diagnosis and treatment of infections.Methods: A cross sectional survey of clinicians attending the 2018 annual scientific conference and general meeting of the National Postgraduate Medical College of Nigeria (NPMCN) in Owerri, Southeastern Nigeria, was conducted using self-administered structured questionnaire to obtain information on the sub-optimal utilization of the clinical microbiology laboratory. Results: Of 283 respondents, 14.8% were general practitioners and 85.2% were specialists who have been in practice for a median period of 20 years (range 3 – 48 years). The specialists included surgeons (26%), family physicians (19.8%), internists (14.3%), pathologists (13.9%), paediatricians (8.8%), obstetricians and gynecologists (8.1%), community medicine physicians (6.2%), and dental surgeons (2.6%). Majority of the respondents (90.8%) work in public, 88.3% work in tertiary and 9.9% in secondary care hospitals. For diagnosis of infections, 16% and 49.8% reported using laboratory “always” and “very often” respectively. Among these, the most commonly utilized investigations were microscopy, culture and sensitivity (62.4%), DNA detection (18.3%), GeneXpert for tuberculosis (17.2%), and antigen detection (16.7%). Among clinicians that “hardly make use” of the laboratory, their reasons for non-use were; clinical diagnosis being sufficient (39.7%), delayed results (17.2%), having knowledge of „potent‟ antibiotics (15.5%), lack of access to microbiology laboratory (13.8%), absence of pathologists to assure quality of tests (12.1%), and no need of the laboratory to manage patients with infections (8.6%).Conclusion: These findings indicate that poor use of the microbiology laboratory seems mainly associated with perception and attitude of the physicians to the relevance of the laboratory, and perceived inadequacy of microbiology practice in some others. There is need to raise physicians‟ awareness on the relevance and what constitutes optimal use of the clinical microbiology laboratory for accurate diagnosis of infections and appropriate antimicrobial use.Key words: utilization, microbiology laboratory, diagnosis, antimicrobials, infectious disease

Antimicrobial Stewardship Implementation in Nigerian Hospitals: Gaps and Challenges
Background: Antimicrobial resistance (AMR) is a major clinical challenge globally. It is mainly a consequence of inappropriate prescribing and use of antibiotics. Antimicrobial stewardship (AMS) ensures that antibiotics are prescribed and used appropriately. This study assessed AMS practice in selected Nigerian hospitals.Methodology: This was a cross sectional survey of 20 Federal, State and Private tertiary hospitals randomly selected from the six geopolitical zones of Nigeria. Using an adapted WHO tool on AMS, data were collected from each hospital as regard the existence of AMS committee, Accountability and Responsibility, AMS actions, Education and Training, Monitoring and Evaluation, Infection Prevention and Control (IPC) practice, facilities to support AMS, and challenges to AMS implementation. Gaps and challenges to the implementation of the AMS among the hospitals were identified.Results: Only 6 (30%) of the 20 hospitals had AMS committees while 2 (10%) had any evidence of leadership commitment to AMS. All the hospitals had laboratory facilities to support culture and sensitivity testing. There were no regular AMS-related education or training, monitoring, evaluation or reporting activities in the hospitals, except in 7 (25%) that had participated in the global point prevalence survey (Global-PPS) of antimicrobial use and resistance being hosted by the University of Antwerp, Belgium. Challenges impeding AMS activities included lack of human and financial resources, prescribers’ opposition, lack of awareness and absence of AMS committees. Most of the gaps and challenges bordered on seeming lack of knowledge and inadequate communication among prescribers and other stakeholders.Conclusion: There is need for intense education and training activities for prescribers and other stakeholders, including but not limited to hospital administrators.

French title: Mise en œuvre de la gestion des antimicrobiens dans les hôpitaux Nigérians: lacunes et défis
Contexte: La résistance aux antimicrobiens (RAM) est un défi clinique majeur à l'échelle mondiale. C'estprincipalement une conséquence d'une prescription et d'une utilisation inappropriées d'antibiotiques. La gestion des antimicrobiens (AMS) garantit que les antibiotiques sont prescrits et utilisés de manière appropriée. Cette étude a évalué la pratique de l'AMS dans certains hôpitaux Nigérians.
Méthodologie: Il s'agissait d'une enquête transversale de 20 hôpitaux tertiaires fédéraux, d'État et privéssélectionnés au hasard dans les six zones géopolitiques du Nigéria. À l'aide d'un outil OMS adapté sur l'AMS, des données ont été collectées auprès de chaque hôpital en ce qui concerne l'existence d'un comité AMS, la responsabilité et la responsabilité, les actions AMS, l'éducation et la formation, le suivi et l'évaluation, la pratique de prévention et de contrôle des infections (IPC), les installations pour soutenir l'AMS. et les défis de la mise en œuvre de l'AMS. Les lacunes et les défis liés à la mise en œuvre de l'AMS parmi les hôpitaux ont été identifiés.
Résultats: Seuls 6 (30%) des 20 hôpitaux avaient des comités AMS tandis que 2 (10%) avaient des preuves d'engagement du leadership envers l'AMS. Tous les hôpitaux disposaient d'installations de laboratoire pour soutenir la culture et les tests de sensibilité. Il n'y avait pas d'activités régulières d'éducation ou de formation, de suivi, d'évaluation ou de rapportage liées à la MGS dans les hôpitaux, sauf dans 7 (25%) qui avaient participé à l'enquête mondiale sur la prévalence ponctuelle (Global-PPS) de l'utilisation et de la résistance aux antimicrobiens organisée par l'Université d'Anvers, Belgique. Les défis entravant les activités de l'AMS comprenaient le manque de ressources humaines et financières, l'opposition des prescripteurs, le manque de sensibilisation et l'absence de comités AMS. La plupart des lacunes et des défis se limitaient à un manque apparent de connaissances et à une communication inadéquate entre les prescripteurs et les autres intervenants.Conclusion: Des activités d'éducation et de formation intensives sont nécessaires pour les prescripteurs et autres intervenants, y compris, mais sans s'y limiter, les administrateurs d'hôpitaux.
