Introduction Pre-analytical errors in cytology laboratories can significantly impact the accuracy of diagnostic results and turnaround times, ultimately affecting patient care. This article presents an evaluation of pre-analytical errors and proposes fostering strategies to enhance accuracy and efficiency in the cytology laboratory of a tertiary care hospital. The background discusses the importance of pre-analytical processes in ensuring reliable cytological diagnoses and the common errors encountered in specimen collection, handling, and transportation. Strategies for error reduction and improvement in turnaround times include staff education, standardization of procedures, utilization of appropriate collection and transport devices, implementation of quality control measures, and utilization of automation technologies. By addressing pre-analytical errors and implementing fostering strategies, cytology laboratories can optimize diagnostic accuracy, improve patient care outcomes, and enhance overall laboratory efficiency. Aims and objectives This study aims to assess the prevalence and nature of pre-analytical errors in the cytology laboratory of a tertiary care hospital to understand the extent of the issue, identify the specific factors contributing to pre-analytical errors like specimen collection, handling, and transportation processes, and pinpoint areas for improvement. It seeks to evaluate the impact of pre-analytical errors on the accuracy of cytological results and the efficiency of turnaround times, highlighting the consequences for patient care. Furthermore, the study aims to develop targeted strategies to minimize pre-analytical errors and enhance the accuracy of cytological results. Materials and methods This study was conducted at the Cytology Laboratory of our hospital from January 2023 to December 2023 after getting proper approval from the Institutional Review Board (IRB approval number 101/02/2024/PG/SRB/SMCH). It is a retrospective analytical study, and a total of 5412 samples from patients of the outpatient (OP) department, inpatient (IP) department, and community health outreach program facilities received in the cytology laboratory were analyzed during the study period. The inclusion criteria were the test samples sent specifically for cytological analysis. The samples sent for biochemical or microbiological examination were excluded. The frequency of sample distribution and rejected samples were calculated and the results were correlated. Results A total of 5,412 samples received in the cytology laboratory were analyzed during the study period. The majority of the samples were Papanicolaou smears (2,352, 43.5%), followed by fluid cytology (1,008, 18.6%) and ultrasound-guided fine-needle aspiration cytology (FNAC, 984, 18.2%). Of the total number of samples, 225 (4.16%) were repeated and 27 (0.5%) were rejected. Conclusions Pre-analytical, analytical, and post-analytical processes are the three key factors that determine the dependability and precision of cytological test results. Detecting critical alerts such as the positivity of malignancy underscores the paramount importance of result accuracy. Implementing good laboratory practices and conducting both external and internal audits can reduce the frequency of preventable errors in a cytology laboratory, thereby ensuring enhanced precision and expedited outputs.
引言 细胞学实验室的分析前误差会显著影响诊断结果的准确性和周转时间,最终影响患者护理。本文对分析前误差进行评估,并提出促进策略以提高三级护理医院细胞学实验室的准确性和效率。背景部分讨论了分析前过程在确保可靠的细胞学诊断中的重要性以及标本采集、处理和运输中常见的误差。减少误差和缩短周转时间的策略包括员工教育、程序标准化、使用合适的采集和运输设备、实施质量控制措施以及利用自动化技术。通过解决分析前误差并实施促进策略,细胞学实验室可以优化诊断准确性、改善患者护理结果并提高整体实验室效率。
目的 本研究旨在评估三级护理医院细胞学实验室分析前误差的发生率和性质,以了解问题的严重程度,确定导致分析前误差的具体因素,如标本采集、处理和运输过程,并找出改进的领域。它旨在评估分析前误差对细胞学结果准确性和周转时间效率的影响,突出对患者护理的后果。此外,该研究旨在制定有针对性的策略,以尽量减少分析前误差并提高细胞学结果的准确性。
材料和方法 本研究于2023年1月至2023年12月在我院细胞学实验室进行,获得了机构审查委员会的适当批准(IRB批准号101/02/2024/PG/SRB/SMCH)。这是一项回顾性分析研究,在研究期间对细胞学实验室接收的来自门诊(OP)、住院(IP)部门和社区卫生外展项目设施的5412份患者样本进行了分析。纳入标准是专门送检进行细胞学分析的测试样本。排除送检进行生化或微生物学检查的样本。计算样本分布频率和拒收样本,并对结果进行关联分析。
结果 在研究期间,对细胞学实验室接收的总共5412份样本进行了分析。大多数样本是巴氏涂片(2352份,43.5%),其次是液基细胞学(1008份,18.6%)和超声引导下细针穿刺细胞学检查(FNAC,984份,18.2%)。在所有样本中,225份(4.16%)是重复样本,27份(0.5%)被拒收。
结论 分析前、分析中和分析后过程是决定细胞学检测结果可靠性和精确性的三个关键因素。检测诸如恶性肿瘤阳性等关键警报突出了结果准确性的至关重要性。实施良好实验室规范并进行外部和内部审核可以减少细胞学实验室中可预防误差的频率,从而确保提高精确性和加快产出。
