影響實(shí)驗(yàn)室數(shù)據(jù)完整性的過(guò)程,有以下幾方面:
樣品的完整性
標(biāo)準(zhǔn)物質(zhì)和溶液的完整性
實(shí)驗(yàn)室儀器和計(jì)算機(jī)化系統(tǒng)
熟練的分析人員
記錄和結(jié)果報(bào)告
分析方法驗(yàn)證和確認(rèn)

An inventory of computerised systems was available. |
有一份計(jì)算機(jī)化系統(tǒng)的清單。 |

Electronic data was backed up at appropriate regular intervals in accordance with SOP titled as “The guidelines for creating backup copies of electronic data”. Software systems associated to the instruments were connected to a backup program. Additionally, data was regularly saved on an external hard drive, under appropriate supervision. Another backup copy was prepared once a year. |
電子數(shù)據(jù)按照名為“電子數(shù)據(jù)備份指南”的SOP,按適當(dāng)?shù)亩ㄆ陂g隔進(jìn)行備份。與儀器相關(guān)的軟件系統(tǒng)被連接到一個(gè)備份程序。此外,數(shù)據(jù)定期保存在一個(gè)外部硬盤中,并有適當(dāng)?shù)谋O(jiān)管。每年再進(jìn)行一次備份。

Concerning spreadsheets (e.g. Excel®), all cells including calculations were locked so that formulas could not accidentally be overwritten. Free access was only given to cells to be filled in with data. Calculation algorithms were properly tested and confirmed. The validated Excel spreadsheets were uploaded in the LIMS database system to provide protected access by QA who also supervised and handled the obsolete versions. The used spreadsheets were stored on the server in a specific folder. The sheets were also printed out to be attached to the analytical documentation. |
對(duì)于電子表格(如Excel®),所有單元格包括計(jì)算都被鎖定,因此公式不會(huì)意外被覆蓋。只有要用數(shù)據(jù)填充的單元格才可以自由訪問(wèn)。對(duì)計(jì)算算法進(jìn)行了適當(dāng)?shù)臏y(cè)試和驗(yàn)證。經(jīng)過(guò)驗(yàn)證的Excel電子表格被上載到LIMS數(shù)據(jù)庫(kù)系統(tǒng)中,以提供QA的保護(hù)訪問(wèn),QA還監(jiān)督和處理過(guò)時(shí)的版本。使用的電子表格存儲(chǔ)在服務(wù)器的特定文件夾中。這些表格也打印出來(lái),附在原始記錄中。

Validation of computerized systems was initiated in accordance with an SOP for Computerized Systems validation protocol. This SOP was mainly related to the transfer of data from computer to the backup server for security of storage of electronic data. The transfer of data from LIMS database to the backup server was validated. |
根據(jù)計(jì)算機(jī)化系統(tǒng)驗(yàn)證方案的SOP啟動(dòng)計(jì)算機(jī)化系統(tǒng)驗(yàn)證。該SOP主要涉及數(shù)據(jù)從計(jì)算機(jī)傳輸?shù)絺浞莘?wù)器,以保證電子數(shù)據(jù)存儲(chǔ)的安全性。驗(yàn)證了將數(shù)據(jù)從LIMS數(shù)據(jù)庫(kù)傳輸?shù)絺浞莘?wù)器。

我們可以看出檢查官在現(xiàn)場(chǎng)檢查時(shí),查看了計(jì)算機(jī)化系統(tǒng)的清單、電子數(shù)據(jù)的備份管理、Excel®的驗(yàn)證以及計(jì)算機(jī)化系統(tǒng)的驗(yàn)證,這與WHO TRS No.1033 數(shù)據(jù)完整性指南中的 9. Data, datatransfer and data processing數(shù)據(jù),數(shù)據(jù)轉(zhuǎn)移和數(shù)據(jù)處理以及 11.Computerized systems計(jì)算機(jī)化系統(tǒng)的要求是一致的。雖然在報(bào)告中沒(méi)有描述訪問(wèn)和權(quán)限以及審計(jì)追蹤的相關(guān)內(nèi)容,但是這些內(nèi)容是實(shí)驗(yàn)數(shù)據(jù)完整性要求的基礎(chǔ)。在實(shí)際的工作中,我們要法規(guī)結(jié)合檢查的案例,才能更好的完善QC實(shí)驗(yàn)室數(shù)據(jù)完整性。
