Quality Management System (QMS) Performance of Medical Laboratories in Secondary and Tertiary Healthcare Facilities in Nigeria: Results of a Multi-Facility Assessment Using the WHO SLIPTA Framework

In the quiet, often unseen corners of hospitals, a critical process determines whether a patient receives the right treatment or a dangerous mistake. Before a doctor prescribes medicine or performs surgery, they rely on data generated by medical laboratories. These facilities test blood, tissue, and other samples to confirm infections, track diseases, and guide life-saving decisions. If the machinery is faulty, the staff is untrained, or the records are messy, the results become unreliable. When a lab result cannot be trusted, patient safety collapses, and the entire health system falters. To prevent this, laboratories need a quality management system. This is not a single machine or a specific test, but a set of organized rules and routines that ensure every step of the process is accurate, repeatable, and safe. International standards exist to define what a competent laboratory looks like, but in many parts of the world, reaching that standard is a steep climb.

A recent study conducted by researchers from the Federal Ministry of Health and Social Welfare in Nigeria sought to understand exactly where the country stands on this climb. The team focused on sixty public medical laboratories located in secondary and tertiary hospitals across the nation. These are facilities that handle routine testing for general hospitals as well as complex cases for major teaching centers. To measure their performance, the researchers used a specialized checklist developed by the World Health Organization. This tool, known as the Stepwise Laboratory Quality Improvement Process, evaluates a lab across twelve different areas, ranging from how they manage their staff and equipment to how they handle mistakes and improve their work over time. Based on the assessment, each laboratory receives a score and a star rating, similar to how hotels are rated, but here the stars indicate how close the lab is to meeting international safety standards. The goal was to move beyond isolated reports and get a clear, national picture of the strengths and weaknesses in Nigeria's diagnostic network.

The researchers deployed fifty-eight certified auditors to visit sixty laboratories in thirty-six states and the Federal Capital Territory. These auditors did not just look at the equipment; they examined the daily routines, the paperwork, the leadership structures, and the culture of the labs. They used digital tools to record their findings on the spot, ensuring the data was accurate and consistent. When the dust settled, the results revealed a stark reality: the majority of these laboratories are struggling to meet even the most basic requirements for quality. Out of the sixty labs assessed, forty-seven achieved the lowest possible rating, meaning they had not yet reached the threshold for a single star. Only three laboratories managed to reach a four-star rating, and none reached the highest level of five stars. This indicates that for most of these facilities, the systems needed to guarantee safe and accurate results are either missing or functioning poorly.

The study also uncovered a distinct pattern in where the problems lie. The auditors found that the laboratories were actually quite good at managing their supplies and keeping track of their inventory. They could generally show where their reagents and equipment were stored. However, the labs fell apart when it came to the more complex, human-driven aspects of quality. The weakest areas were leadership, internal auditing, and the ability to continuously improve. In plain terms, the labs knew how to stock their shelves, but they lacked the leadership to organize their teams, the systems to check their own work for errors, and the culture to fix those errors when they happened. The domains of assessment and continuous improvement scored the lowest, suggesting that the managers and staff were not regularly reviewing their processes or learning from their mistakes.

Geography played a significant role in these findings. The performance of the laboratories varied wildly depending on their location. The best-performing region was the South-West, where the average score was significantly higher than in other parts of the country. In contrast, the South-South region had the lowest average performance. A closer look at the top-performing labs revealed that they were not spread evenly across the nation. All three of the four-star laboratories were located in Lagos State, a region that has benefited from specific government-led initiatives and donor support. This suggests that while targeted investment can produce rapid improvements, the benefits have not yet reached the rest of the country. The gap between the well-supported labs in Lagos and the struggling labs elsewhere highlights a fragmented system where quality is not a national standard but a local privilege.

The researchers concluded that the path forward requires more than just buying new microscopes or reagents. The data suggests that the barriers to quality are not primarily technical but managerial. To improve, these laboratories need strong leadership that prioritizes quality, a workforce trained to identify and fix problems, and a culture where continuous improvement is a daily habit rather than an occasional event. The study points out that the government and its partners must coordinate their efforts to support the weaker regions, particularly the South-South and South-East zones. By focusing on building leadership capacity and integrating quality practices into the daily routine of every lab, Nigeria can begin to close the gap. The ultimate aim is to move every laboratory toward full international accreditation, ensuring that no matter where a patient goes in the country, the lab results they receive are trustworthy and safe.
