探讨运用PDCA(plan、do、check、action)循环理论提高生物样本库信息系统管理质量的效果。

江苏省苏北人民医院生物样本库根据PDCA循环理论，收集2015年至2017年期间，执行PDCA循环前后生物样本库入库标本量数据，并对入库标本的相关临床信息采集完整性及功能模块响应时间变化进行比对分析。

与执行PDCA循环前相比，执行PDCA循环后入库标本量由3485份增加至22 241份，其中：肝癌标本5118份、肺癌标本6343份、前列腺癌标本2870份、胰腺癌标本4294份、胃肠癌标本3616份；全院临床基本信息、入院信息、手术信息、检验信息、病理信息、影像信息及随访信息的采集不断完善，已达到规范性和完整性要求；各功能模块运行响应时间显著缩短，所有入库标本检索时间由17 s缩至2 s，所有患者检索时间由7 s缩短至0.5 s，问卷管理、容器管理及随访管理响应时间也依次缩短(分别为5至0.3 s, 4 s至0.5 s, 8 s至0.2 s)。

采用PDCA循环理论用于生物样本库信息系统管理中，可提高临床信息采集的规范性和完整性，降低功能模块运行的响应时间。

To explore the effect of using the PDCA (plan, do, check, action) cycle theory in biobank information management system.

On the basis of PDCA cycle theory, quantity data of stored specimens in Biobank of Northern Jiangsu People's Hospital from 2015 to 2017 was obtained. The integrity of clinical information acquisition and the change of response time of the functional modules were analyzed.

Compared with pre-execution PDCA, the implementation of PDCA increased the storage samples from 3485 to 22 241 (5118 liver cancer samples, 6343 lung cancer samples, 2870 prostate cancer samples, 4294 pancreatic cancer samples, 3616 gastrointestinal carcinoma samples). Clinical information, admission information, surgical information, inspection information, pathological information, image information and follow-up information had been collected normalization and integrity. Response time of each function module was significantly shortened: the time for all sample retrieval function reduced from 17 s to 2 s, the time for all the patients search function reduced from 7 s to 0.5 s. The time for questionnaire management, container management and follow-up management response is also shorten greatly (form 5 s to 0.3 s, 4 s to 0.5 s and 8 s to 0.2 s, respectively).

The application of PDCA cycle theory in biobank management information system can improve the normative and integrity of clinical information collection, it can also reduce the response time of the function modules.
