This article describes Pathologists Overseas (PO) experience supporting external quality assessment (EQA) programs in 10 clinical laboratories across 3 countries between 2009 and 2017.
Laboratories were enrolled in the condensed chemical pathology EQA program provided by the Royal College of Pathologists of Australasia Quality Assurance Program. Participants were given an initial 2- to 4-day in-person training, followed by 1 year of active feedback on performance via emails or phone calls by a PO volunteer.
There were 2 performance metrics: percentage of reported results as a measure of compliance and percentage of acceptable reported results as a measure of accuracy. Laboratories demonstrated high compliance with result reporting, with medians of 69.9%, 71.7%, and 81.3% before, during, and after feedback, respectively. Concomitant medians for the percentage of acceptable reported results were 41.2%, 57.3%, and 53.5%, respectively. Six laboratories had low performance in terms of accuracy at baseline (<60%). Active feedback improved the percentage of acceptable reported results for these lower-performing laboratories.
External quality assessment programs can be successfully adopted long term by laboratories in low-resource settings. Active feedback requires significant time and effort but could be especially beneficial for laboratories with poor baseline performance.
本文描述了海外病理学家(PO)在 2009 年至 2017 年间,在 3 个国家的 10 个临床实验室支持外部质量评估(EQA)计划的经验。
实验室参加了由澳大利亚皇家病理学家学院质量保证计划提供的浓缩化学病理学 EQA 计划。参与者接受了为期 2-4 天的面对面初始培训,然后由 PO 志愿者通过电子邮件或电话提供为期 1 年的关于表现的积极反馈。
有 2 个绩效指标:报告结果的百分比作为合规性的衡量标准,以及可接受的报告结果的百分比作为准确性的衡量标准。实验室在报告结果方面表现出很高的合规性,分别在反馈前、反馈中和反馈后的中位数为 69.9%、71.7%和 81.3%。同时,可接受报告结果的百分比中位数分别为 41.2%、57.3%和 53.5%。有 6 个实验室在准确性方面的表现较差(<60%)。积极的反馈提高了这些表现较差的实验室的可接受报告结果的百分比。
外部质量评估计划可以长期被资源较少的实验室成功采用。积极的反馈需要大量的时间和精力,但对于基线表现不佳的实验室可能特别有益。
