Abstract

Objectives: Automation of test follow-up offers potential reductions in workload for clinicians. The primary objective of the study was to evaluate the performance of MicrobEx, a regular expression-based algorithm in classifying urine culture reports in primary care.

Methods: A retrospective validation of MicrobEx was performed using urine culture reports abstracted from a single academic family health team. MicrobEx classifications were compared with labels assigned manually by a human reviewer. Measures of diagnostic performance were calculated.

Results: MicrobEx achieved 95.3% accuracy, 88.6% sensitivity, and 100% specificity in classifying 1,999 urine culture reports.

Conclusion: The accuracy of MicrobEx was comparable to its performance in the original development and validation study by Eickelberg. Additional work is required to explore and improve the accuracy of MicrobEx and assess its performance across primary care settings and with more complex urine culture reports.

家庭医学中尿液培养物分类算法的验证。

目的：测试随访的自动化为临床医生提供了潜在的工作量减少。本研究的主要目的是评估MicrobEx的性能，MicrobEx是一种基于正则表达式的算法，用于对初级保健中的尿液培养报告进行分类。方法：回顾性验证MicrobEx使用尿培养报告从一个学术家庭健康团队。将MicrobEx分类与人工审稿人手动分配的标签进行比较。计算诊断性能的度量。结果：MicrobEx对1999例尿培养报告的分类准确率为95.3%，灵敏度为88.6%，特异性为100%。结论：MicrobEx的准确度与Eickelberg最初开发和验证研究中的性能相当。需要进一步的工作来探索和提高MicrobEx的准确性，并评估其在初级保健环境和更复杂的尿液培养报告中的表现。

期刊介绍： ACI is the third Schattauer journal dealing with biomedical and health informatics. It perfectly complements our other journals Öffnet internen Link im aktuellen FensterMethods of Information in Medicine and the Öffnet internen Link im aktuellen FensterYearbook of Medical Informatics. The Yearbook of Medical Informatics being the “Milestone” or state-of-the-art journal and Methods of Information in Medicine being the “Science and Research” journal of IMIA, ACI intends to be the “Practical” journal of IMIA.
