Blood cultures (BC) are a complex multistep process susceptible to errors at multiple levels. Our study was conducted to monitor the compliance to standard operating procedures, design an intervention plan for improvement and monitor the impact of the intervention. The study design focuses on the intervention.
A hospital-based prospective interventional study was carried out, monitoring various pre-analytical, analytical, and post-analytical factors in two phases. Our interventions focused on communication and training for the deficiencies noted in completeness of test request form, contamination rates, and sample loading interval.
Comparison between both phases showed a statistically significant improvement (p < 0.05, Chi square test) following our interventions in the completeness of test request form, contamination rates and sample loading interval. There was an improvement in the intimation of critical Gram stain from positive flagged bottles, which was not statistically significant.
Our study highlights how educational interventions can influence quality of BC. Continuous monitoring and interventions are key for quality improvement in BC processes.
血培养(BC)是一个复杂的多步骤过程,在多个层面都容易出错。我们开展这项研究是为了监测对标准操作程序的依从性,设计改进干预计划并监测干预效果。该研究设计聚焦于干预措施。
开展了一项基于医院的前瞻性干预研究,分两个阶段监测各种分析前、分析中和分析后因素。我们的干预措施针对检验申请表完整性、污染率和样本加载间隔方面发现的不足,着重于沟通和培训。
两阶段比较显示,在我们针对检验申请表完整性、污染率和样本加载间隔采取干预措施后,有统计学意义上的显著改善(p < 0.05,卡方检验)。阳性标记瓶关键革兰氏染色的通报有所改善,但无统计学意义。
我们的研究凸显了教育干预如何能够影响血培养质量。持续监测和干预是改善血培养流程质量的关键。
