Translating laboratory quality management system into practice: strategic opportunities and challenges for ISO 15189:2022 implementation in Nigeria's healthcare system.
Review in Frontiers in health services, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Laboratory Quality Management Systems (LQMS) are fundamental to reliable diagnostic services and improved patient outcomes. Although Nigeria has made progress through quality improvement initiatives, implementation of internationally recognized standards remains limited. This review critically examines the relevance of ISO 15189:2022 for strengthening laboratory quality systems in Nigeria by evaluating its major revisions, current implementation status, challenges, opportunities, and evidence-based strategies for national adoption. Methods: A structured narrative review was conducted using evidence published between January 2010 and July 2026. Electronic databases (PubMed, PubMed Central, Web of Science, and Google Scholar) and institutional sources (WHO-AFRO, ASLM, MLSCN, NiNAS, and ILAC) were systematically searched. Evidence selection followed a PRISMA-informed process, while reporting adhered to the SANRA guideline. Of 379 records identified, 55 met the inclusion criteria, with 49 synthesized thematically and six retained for foundational and conceptual support. Results: The evidence showed that LQMS implementation in Nigeria remains heterogeneous, with stronger performance in donor-supported reference laboratories than in many public facilities. SLMTA and SLIPTA programmes have improved laboratory audit performance, including in Lagos State, yet fewer than 30 of Nigeria's over 5,000 clinical laboratories are currently ISO 15189 accredited. Major barriers include fragmented governance, inadequate financing, weak infrastructure, workforce shortages, limited digital integration, and poor quality culture. ISO 15189:2022 introduces patient-centred, risk-based quality management, integrated point-of-care testing, and flexible documentation, creating opportunities to modernize laboratory practice through strengthened governance, digital transformation, workforce development, and sustained investment. Conclusion: ISO 15189:2022 provides a practical framework for improving laboratory quality and technical competence in Nigeria. Successful implementation will require coordinated regulatory reforms, expanded stepwise quality improvement programmes, sustained financing, workforce capacity building, and digital innovation to strengthen diagnostic services and support resilient health systems.
