Data integrity is crucial for laboratories, particularly for regulatory compliance such as 21 CFR Part 11 and Eudralex Annex 11, and it encompasses the completeness, accuracy, and consistency of data throughout its life cycle. The document outlines the challenges organizations face in achieving data integrity and emphasizes the importance of understanding data architecture, while introducing technologies like Electronic Lab Notebooks (ELN) and Scientific Data Management Systems (SDMS) as solutions. By adhering to guidelines like ALCOA and CCEA, systems can ensure data is attributable, legible, contemporaneous, original, accurate, complete, consistent, enduring, and available for audits.

- 1. DATA INTEGRITY Data integrity, an area of increasing priority in today’s laboratory world and “The focus area” when it comes to regulatory compliance such as 21 CFR Part 11 and Eudralex Annex 11. Considering the number of warning letters from USFDA and other such regulatory bodies issued to pharmaceutical and medical devices manufacturers across the globe, Data integrity is the “Buzz word” in today’s audit. WHAT IS DATA INTEGRITY? Data integrity refers to the overall completeness, accuracy and consistency of data during its entire life cycle. Though seems simple, the whole process of genuinely generating, maintaining & transforming data with completeness and accuracy is a challenging task for any organization. This white paper discusses the issues faced by organizations in achieving data integrity and briefly describes how and what technology can be effectively used to achieve better data integrity. PROBLEMS FACED BY ORGANISATIONS IN UNDERSTANDING DATA INTEGRITY Most organisations figure out the process of data management which will include capture and archival but fail to understand the core requirement in accomplishing its integrity. For data integrity, it’s important to know the “data architecture” of the system. This understanding is key in setting up the focus area and methodologies to achieve better integrity. DATA INTEGRITY GUIDELINES BY REGULATORY BODIES FDA has been adopting the ALCOA attributes to verify data integrity Attributable - Defining Source data and who performed an action on it. Legible - Permanent recording of information and Access to easy reading any time Contemporaneous- Recording the date & time when work is performed Original - Justifying if the information / data is a true copy Accurate - Is the data accurate, with no errors or editing

Additional terms based on European Medicines Agency’s concept the following acronyms also emerged (CCEA) Complete - All data including repeat or re-analysis performed on the sample Consistent - Consistent application of date & time stamps in the expected sequence Enduring - Recorded in controlled worksheets, laboratory notebooks or electronic media Available - Available /accessible for review/ audit for the life time of the record DATA LIFE CYCLE A typical data life cycle can be broken up into the following stages: Generation & Recording (including raw data) Processing (including transformation or migration) Retention Retrieval/ Archival Destruction Fig. 1 Data Life Cycle
- 3. info@agaramtech.com www.agaramtech.com ALCOA-CCE TO ACHIEVE FDA & EUDRALEX COMPLIANCE Adherence to ALCOA-CCE will definitely lead to 21 CFR Part 11 and Eudralex Annex 11 compliance for regulated laboratories. Consider implementing an Electronic Lab Notebook (ELN) and/or a Scientific Data Management System (SDMS) to achieve compliance. Following sections gives you an idea about how these solution help in meeting the guidelines. ATTRIBUTABLE: DEFINING SOURCE DATA AND WHO PERFORMED AN ACTION ON IT. ELN and SDMS systems are instrument & user centric and hence will help easily identifying the data source i.e. which instrument generated the data. Whereas the ELN which is user interface oriented will be able to also track who performed the action. i.e. who generated and collected the data from the instrument. LEGIBLE: PERMANENT RECORDING OF INFORMATION AND ACCESS TO EASY READING ANY TIME ELN and SDMS both systems record in a central database which is a permanent record. Also the database will reside in a controlled server environment. Data will always be available for accessing and reading for authorised persons. Even archived data can be restored and read through these electronic systems in a seamless manner. Electronic data captured from simple instruments like balance, titrator, pH meter etc. can be easily read even after a very long period of time. This is due to the fact that the communication is direct between the instrument and the software and it is in ASCII. Also data is stored in human readable ASCII format. The life of such data can be eternal (assuming still computers use ASCII). Whereas the output data generated by complex instruments with complex software as described by MHRA’s data integrity guidance (HPLC, LC-MS) is subject to more variables i.e. meta-data along with primary data is required to make sense on the data. This complexity will lead to trouble in terms of longevity of the data in terms of readability. Systems like ELN and SDMS can capture the data and meta- data in an as-is-basis or original format and also a human readable format (pdf). So it becomes important to maintain a copy of the original software that generated the data during the life time of the data. These systems can maintain such data for a very long period of time CONTEMPORANEOUS: RECORDING THE DATE & TIME WHEN WORK IS PERFORMED Both ELN and SDMS can allow usage or recording of data in a contemporaneous manner i.e. recording of details can happen as and when an activity is being conducted. At the same time they can record the date and time at which the data was captured which is real-time for simple instruments. Whereas for the complex pc controlled instruments the date/time of a file generated by

ORIGINAL: JUSTIFYING IF THE INFORMATION / DATA IS A TRUE COPY Data captured is always true and directly from instrument (if it is via a port like RS232 or TCP/IP). Also for the complex instrument it is the original file generated by the instrument software that is captured. After a file is generated and if it is modified by some means (mostly through the instrument software) these software systems will capture the new modified file and version it automatically. CFR Gateway Agaram has developed a unique solution called as “CFR Gateway” to cater to this specific requirement. i.e. “Original” data/meta-data should never be obscured. CFR gateway when used along with SDMS/ELN will never allow the instrument software user to delete, rename, save-as, copy, paste files which are monitored by it. This means “Original” data cannot be compromised at any point and time. ACCURATE: IS THE DATA ACCURATE, WITH NO ERRORS OR EDITING Data once generated is always pushed to the server. Whereas the local copy/version of the data in the instrument pc can be still used by the instrument user for better convenience. Even if you open an existing data using the original software and edit the data/meta-data, the system will understand that the data has changed and will push the new version to the server. The system has cross check mechanisms such as check-sum calculations to validate the accuracy of the original data versus the data pushed to the server. If there are any such errors the system has failsafe mechanism to retransmit the data to the server. COMPLETE: ALL DATA INCLUDING REPEAT OR RE-ANALYSIS PERFORMED ON THE SAMPLE SDMS: The system versions the raw and meta data files whenever there is a change in the file or whenever a new set of data is received via the RS232 or TCP/IP port. New versions are stored a separate data files with version number. ELN: Data versioning is available in ELN. i.e. for example if you captured the weight of a sample once and are interested in replacing this weight with another one due to some reason the system will allow you to capture the new weight but will version this new weight and audit trail it with a reason. So any repeat or re-analysis data is always versioned at data level within the ELN CONSISTENT: CONSISTENT APPLICATION OF DATE & TIME STAMPS IN THE EXPECTED SEQUENCE All data capture events and their sequence of capture is data and time stamped. E.g. is possible to go through a pre-determined sequence of events which will be aligned with the actual method of analysis. Each step or

ENDURING: RECORDED IN CONTROLLED WORKSHEETS, LABORATORY NOTEBOOKS OR ELECTRONIC MEDIA Records are stored in electronic media when using SDMS or an ELN. The ELN provides and electronic equivalent of paper worksheets or notebook to capture data in a controlled manner. AVAILABLE: AVAILABLE /ACCESSIBLE FOR REVIEW/ AUDIT FOR THE LIFE TIME OF THE RECORD Data can always be retrieved even after archival and will be accessible for review or audit for the life time of the record. CONCLUSION Scientific Data Management System (SDMS) and Electronic Lab Notebook (ELN) are key solutions that can help laboratories to achieve better data integrity.
