Development and Implementation of an Internal Quality Control and External Quality Assessment Information System for a Regional Medical Laboratory Center: Pilot Design and Implementation Study.
Article in JMIR formative research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundThe Regional Medical Laboratory Center (RMLC) integrates laboratory departments from hospitals with different levels to optimize resource allocation, enhance testing efficiency, and promote the sharing of professional expertise. Despite these benefits, ensuring consistent quality control (QC) across the RMLC presents a significant challenge due to diverse equipment, procedures, and staff expertise levels. To address these challenges, this study provided an information tool called iLab, developed by Shenzhen Huikang Information Technology Co, Ltd, for managing internal quality control (IQC) and external quality assessment (EQA).
objectiveThis study aimed to develop and implement an integrated informatics platform managing IQC and EQA across RMLC.
methodsWe integrated 4 software programs to manage IQC and EQA, laboratory information system (LIS) supplied by Shanghai Tengcheng Medical Tech-Info Co, Ltd; Quality Control Box (QCBOX) and Quality Control EQA Center (QCEC) provided by Bio-Rad Laboratories (Shanghai) Co, Ltd; and the iLab electronic recording system. The platform centralizes QC data processing, with QCBOX and QCEC handling operational workflows, while iLab oversees documentation, analytics, and approval processes. It was successfully deployed in August 2023 across a pilot network comprising 5 district hospitals, 1 central laboratory, and 4 community health stations in Shenzhen's Luohu District.
resultsBy leveraging the LIS-QCBOX data flow, the platform streamlined the entire IQC process, which incorporated interlaboratory comparisons and iLab-facilitated postanalysis management. Concurrently, EQA was enhanced through electronic documentation, multirule analysis of acceptable data, regional proficiency testing via QCEC, and measurement uncertainty (MU) estimation. By September 2025, the platform supported 114 users, integrating 133 instruments and 859 active QC items, and generated 2331 monthly IQC analysis reports, 340 EQA multirule analyses, and 289 MU reports. Comparative analysis revealed marked improvements in key metrics from 2023 (preimplementation) to 2024 (postimplementation): the IQC implementation rate rose from 97.79% to 99.87% (P<.001), the report error rate decreased from 0.048% to 0.027% (P<.001), and the intralaboratory turnaround time compliance rate increased from 95.49% to 95.71% (P<.001). The annual EQA unacceptable rate dropped from 0.34% in 2023 to 0% in 2024. The number of ISO (International Organization for Standardization) 15189-accredited test items increased from 203 in 2022 to 206 in 2024.
conclusionsThe iLab system establishes a scalable framework for standardized IQC and EQA management in RMLC, demonstrating significant potential to enhance regional laboratory quality.
