Abstract

Background:  Specimen losses across the pathology value chain (PVC) result in missed diagnostic opportunities. It is difficult to fully assess these due to the current paper-based systems, with tracking of specimens only possible on the laboratory information system (LIS).

Aim:  This study aimed to assess specimen losses using the paper-based register.

Setting:  Randomly selected Primary health care (PHC) facilities, City of Johannesburg, South Africa.

Methods:  The retrospective descriptive study design was used to scan 1,000 barcodes from facilities in sub-districts A to G. Data was limited to barcodes from the request form and excluded surveillance testing. Matching data from the laboratory repository was extracted. PVC losses were assessed by determining the percentage of scanned barcodes that had a registered, tested, reviewed and/or rejected date. The analysis was stratified according to sub-district, health facility type and test code.

Results:  The dataset analysed included 33 867 barcodes with 121 697 test codes, equating to 3.59 tests per barcode. Matching registered, tested and reviewed dates were detected for 33 107 (97.76%) barcodes. In total, a rejection for one or more test codes was detected for 1,961 barcodes (5.79%). At the sub-district level, between 95.95% (D) and 98.90% (E) of barcodes were reviewed. The rejection rate ranged from 3.27% (F) to 10.93% (D). For community health centres and clinics, 97.37% and 97.97% of the barcodes had a matching reviewed date.

Conclusion:  PVC losses reported were 4.05%, excluding rejections (5.79%), with slightly higher levels noted at the sub-district level. Contribution: The continuous audit of PVC losses is recommended.

评估南非约翰内斯堡市的实验室标本损失。
背景:整个病理价值链(PVC)的标本损失导致错过诊断机会。由于目前的纸质系统,只有在实验室信息系统(LIS)上才能对标本进行跟踪,因此很难对这些指标进行全面评估。目的:本研究旨在评估使用纸质登记的标本损失。环境:随机选择的初级卫生保健(PHC)设施,约翰内斯堡,南非。方法:采用回顾性描述性研究设计,对A至g街道设施的1000个条形码进行扫描。数据仅限于来自申请表的条形码,不包括监测测试。从实验室存储库中提取匹配数据。通过确定具有注册、测试、审查和/或拒绝日期的扫描条形码的百分比来评估PVC损耗。按街道、卫生设施类型和检测规范进行分层分析。结果:分析的数据集包括33 867个条形码和121 697个测试代码,相当于每个条形码3.59个测试。共有33 107个(97.76%)条形码检测到匹配的注册、检测和评审日期。总共有1961个条形码(5.79%)检测到一个或多个测试码的拒绝。街道一级的条形码复核率在95.95% (D) ~ 98.90% (E)之间。拒绝率从3.27% (F)到10.93% (D)不等。对于社区卫生中心和诊所,97.37%和97.97%的条形码具有匹配的审查日期。结论:报告的PVC损失率为4.05%,不包括拒收率(5.79%),街道水平略高。贡献:建议对PVC损失进行持续审计。
