A Digital Infrastructure

In today’s high throughput, data-intensive laboratory environment the principles of QbD, data completeness and integrity should support the functions and operating ethos of any Quality Assurance/Quality Control (QA/QC) operation. Implement a comprehensive, intelligent informatics infrastructure and the job becomes less daunting. This laboratory-focused digital infrastructure is likely to be founded on laboratory information management system (LIMS) functionality to orchestrate test scheduling, manage samples, and automate critical processes. Today’s high-end LIMS will also acquire and channel analytical data directly from measurement and testing instrumentation, offer advanced analytics to support trend identification, and highlight nonconformity and out-of-specification results.

Reducing reliance on paper-based processes, log books and reports may help to improve data security, accuracy and integrity. Having a LIMS solution that offers bidirectional support for key systems means analysts do not have to transcribe results from an instrument panel onto paper or from paper to another manual medium. This helps to ensure data integrity and minimizes errors, but also eliminates data redundancy.

Automation for Critical QA/QC Processes

STARLIMS can be configured to provide key points of automation for a majority of the QA/QC laboratory’s critical processes. The software will generate calculations, reports, workflows, alerts and reminders, as well as trigger retests. Calibration, environmental and stability sample scheduling is similarly automated via STARLIMS, while the software can be configured to issue purchase requests when inventory stocks are low.

QA/QC labs must ensure that any outsourced analytical workflows are managed with the same degree of diligence as in-house operation. Some aspects of QC testing, such as microbiology, are now commonly outsourced to specialized laboratories. From a regulatory perspective, seamless, bidirectional data traffic coming into and flowing out from the QA/QC lab removes error-prone manual data entry stages that could feasibly undo all good works afforded by accompanying digital systems. Therefore, contract partners need to have the same level of secure data management in place, and ideally connect into a conduit for two-way, fully traceable digital data input and transfer.

Supporting Data Integrity and QbD

STARLIMS supports end-to-end assurance of data integrity through traceability of associated processes related to sample or batch, combined with secure sample management capabilities, audit trail, electronic signatures, chain of custody and instrument integration. This collectively minimizes opportunities for human error and unauthorized changes to data. Effectively, all data is traceable, secure and trustworthy.

The intelligent platform supports the QbD concept from early development through to manufacturing. In a QA/QC setting, for example, lab staff can effectively get ahead and prevent changes to product consistency by reviewing process control and trending charts generated in STARLIMS, and so identify variations or anomalies that might impact on manufacturing process or testing.

While it is easy to get overwhelmed by acronyms, marrying a LIMS to a scientific data management system (SDMS), and to electronic laboratory notebook (ELN) capabilities – whether acquired as an add-on or embedded in the LIMS – will further reduce the likelihood of errors that manually transferred data introduces, while ensuring that all standard operating procedures (SOPs) are being adhered to and followed, step-by-step. The addition of ELN capabilities for recording and reporting experiments and data means that in principle, all workflows and processes can be electronically orchestrated at the front end and recorded at the back end.

Advantages of a Holistic Solution

As an end-to-end solution STARLIMS negates those accountability headaches that are inevitably associated with dealing with multiple vendors for system support and issue resolution. Implementing a single, holistic solution also reduces the risk that one or more of the modules or add-ons will not operate as intended, which could impact on validation efforts and project schedules. The advantages of a fully integrated solution are multiple.

A modern LIMS will provide for electronic signatures and a secure audit trail to comply with 21 CFR Part 11, schedule equipment validation, calibration and maintenance, and verify that individual users have the necessary authority and level of training to carry out analytical procedures. Couple this functionality with an understanding of the samples, materials and processes, and with predictive analytics, and the platform can spot trends, highlight outliers and direct out of specification or results to relevant personnel for assessment and action, and/or sign-off, before batch release.

Take a holistic perspective and an ideal LIMS infrastructure – whether on premise or cloud-based – should thus be intuitive, user friendly, and configured to the laboratory’s business rules. The system should offer authorized lab technicians, lab managers, and business executives easy access to key scientific and business decision-making data, in real time, and in digestible formats. The more complete the data, the more insight will be derived for directing next steps, implementing business changes, and maintaining lab operations at the top levels of efficiency.

The ALCOA Effect

Every aspect of QA/QC lab operation, data acquisition, handling and management could come under regulatory scrutiny, so the bottom line is that the lab adheres to the main principles of data integrity, i.e. that data is complete, consistent and accurate, as laid out by FDA in the 2016 data integrity draft guidance. In effect all data should be “attributable, legible, contemporaneously recorded, original or a true copy, and accurate,” (ALCOA), which has become the laboratory mantra for achieving data compliance, whether through electronic or paper-based data management.

While all data created or acquired may be subjected to a regulatory inspection, meeting those ALCOA principles, whatever the data source, destination or format, is more easily achieved when data is acquired electronically. Even so, as set out in a 2017 presentation by the Office of Manufacturing Quality’s Office of Compliance, and the Office of Policy for Pharmaceutical Quality’s Office of Pharmaceutical Quality, at the Society of Quality Assurance Annual Meeting, “paper-based and electronic data record-keeping systems are subject to the same requirement.”

Integration, and the ‘What, Where and How’ of Big Data

The requisite for integrating a LIMS platform directly with analytical or measuring instrumentation is a no brainer, so that data can be captured at source, at the time it was generated. Instrument integration means that the days of cutting and pasting balance printouts, or printing hundreds of pages of chromatographic runs, are well behind us. Configure adequate parallel security into the platform, and results are locked at source so that data can not be changed, deleted or added without authorized reasoning and outcomes. STARLIMS is designed to allow integration with instruments that have RS232 and TCP/IP connections. Data from standalone instruments attached to a computer can also be captured through STARLMS SDMS, as long as the output is readable to the human eye – e.g. in formats such as PDF or Word.

Big data has put pressure on data archiving and storage. Capacity in an SDMS is not an issue, but ‘what’, ‘where’ and ‘how’ to store and retrieve data makes the configuration of silos and the format of stored data critical. An SDMS should make intuitive searching and easy access a matter of course, and help to direct access to contextual information and all metadata, including relevant information on the equipment used, the analyst who carried out the test, reagents and instruments used. From a regulatory viewpoint, and particularly in QC environments, the relationships between data and metadata should also have a baseline assurance of security and traceability. It is virtually impossible to achieve that required level of data security, completeness and inherent integrity, using pen and paper records.

Easy Access and Real Time Monitoring

Electronic solutions can pull up all relevant information attached to a result with just a few clicks. STARLIMS gives lab personnel complete visibility of all processes related to the testing of your sample or lot in one centralize location, from information on the analyst who carried out the task, to data on the instrument and its calibration and maintenance history, specifications of raw materials used to create the final product, and approval of results. By collating all this information in a single platform, electronic systems provide the opportunity to apply trend-based analytics, identify out of specification results and their causes. And critically, results and trends can be monitored and checked in real time, rather than retrospectively, making it possible to pre-empt issues with workflows, SOPs and test failures.

Authorization and Big Brother Oversight

Shared logins and inadequate access authorization steps are other areas for regulatory concern, as is the practice of testing into compliance, essentially retesting batch samples following failure or atypical/out of specification results until acceptable readings are obtained. Implement a secure informatics infrastructure with the necessary compliance-focused features and it becomes virtually impossible to manipulate results without the necessary authorization and validation.

STARLIMS will not allow technicians or analysts to proceed with tasks that they are not qualified or trained to perform, nor assign samples to be tested on instruments that have not been calibrated, or are due for scheduled maintenance. Test Methods are defined within the system and certification requirements are defined for these methods or procedures. The system intelligently supports the prevention of errors that later could be costly and could lead to in lengthy investigations.

Becoming more proactive

Using STARLIMS laboratory managers can be proactive, rather than reactive, and focus their time on value added tasks, while minimizing or completely negating reliance on manual and paper-based processes and systems. Advanced analytics offered by STARLIMS allow managers to oversee the health of their lab, and drill down into operational data to gain greater insights, spot trends, and identify the root cause of negative trends, which supports impact assessment and aids faster decision making.

Exploiting an informatics platform to manage staff, equipment and reagents and consumables can dramatically improve resource management, and optimize the use of existing systems and laboratory resources. The most asset of any lab is its personnel, from technicians, to managers and executives. Allowing people to get on with their primary roles, rather than spend time manually entering, handling and managing data to ensure compliance, further helps to maximize efficiency and make the most of human expertise.
