Abstract

Introduction

The Thai National Guidelines for Hemostatic Laboratory Testing were established in 2018. The guidelines recommend that the 20-min whole blood clotting time (20WBCT) method be used to diagnose/monitor snake bites. The aim of this study was to survey members of the Thailand National External Quality Assessment Scheme (NEQAS) for Blood Coagulation to investigate the use of 20WBCT testing compared between the 2021 post-guideline and 2007 pre-guideline periods.

Methods

In July 2021, questionnaires were sent from the Faculty of Medicine Siriraj Hospital, Mahidol University to 521 Thailand NEQAS for Blood Coagulation member laboratories to survey their WBCT practices. Current WBCT practices were compared with pre-guideline WBCT practices, and chi-square test (x²) was used to test for differences between groups.

Results

Ninety-seven (18.6%) of 521 surveys were returned. Seventy-one laboratories (73.2%) reported knowing about 20WBCT from the Thai national guidelines. The reported average frequency of overall WBCT testing in 2021 was 12.4 times/month. The proportion of laboratories that reported using the 20WBCT test increased from 2.0% in 2007 to 46.4% in 2021 (p < 0.001), and the indications for performing WBCT were virtually unchanged from 2007 to 2021. The proportion of laboratories that reported having problems with WBCT testing decreased from 32.7% in 2007 to 16.5% in 2021.

Conclusion

Despite our findings that almost three-quarters of respondent laboratories reported knowing about 20WBCT testing from the WBCT guidelines, and that WBCT-specific problems decreased significantly from 2007 to 2021, more work and training is needed to improve WBCT guideline dissemination, understanding, and adherence in Thailand.

全血凝固时间：泰国国家血液凝固外部质量评估计划成员实验室的现行做法。

导言：泰国国家止血实验室检测指南于2018年制定。该指南建议使用 20 分钟全血凝固时间（20WBCT）法诊断/监测蛇咬伤。本研究旨在对泰国国家血液凝固外部质量评估计划（NEQAS）成员进行调查，以了解 2021 年指南发布后与 2007 年指南发布前的 20WBCT 检测使用情况对比：方法：2021 年 7 月，玛希隆大学 Siriraj 医院医学系向 521 家泰国血液凝固NEQAS 成员实验室发出问卷，调查他们的 WBCT 检验方法。将目前的 WBCT 实践与指南发布前的 WBCT 实践进行比较，并使用卡方检验（x2 ）检验组间差异：结果：521 份调查问卷中有 97 份（18.6%）被收回。71家实验室（73.2%）报告说从泰国国家指南中了解了20WBCT。据报告，2021 年总体 WBCT 检测的平均频率为 12.4 次/月。报告使用 20WBCT 检测的实验室比例从 2007 年的 2.0% 增加到 2021 年的 46.4%（p 结论）：尽管我们的研究结果表明，几乎四分之三的受访实验室报告说从 WBCT 指南中了解了 20WBCT 检测，而且从 2007 年到 2021 年，WBCT 特定问题显著减少，但仍需开展更多工作和培训，以改善 WBCT 指南在泰国的传播、理解和遵守情况。

期刊介绍： The International Journal of Laboratory Hematology provides a forum for the communication of new developments, research topics and the practice of laboratory haematology. The journal publishes invited reviews, full length original articles, and correspondence. The International Journal of Laboratory Hematology is the official journal of the International Society for Laboratory Hematology, which addresses the following sub-disciplines: cellular analysis, flow cytometry, haemostasis and thrombosis, molecular diagnostics, haematology informatics, haemoglobinopathies, point of care testing, standards and guidelines. The journal was launched in 2006 as the successor to Clinical and Laboratory Hematology, which was first published in 1979. An active and positive editorial policy ensures that work of a high scientific standard is reported, in order to bridge the gap between practical and academic aspects of laboratory haematology.
