Introduction
Chromatography data systems have been in laboratories for many years in many forms:
• integrator
• single PC
• central data system
• client/ server or networked system.
Functions of CDS
In outline the process used by most CDS consists of all or most of
the points below:
• Set up the method and analytical run information.
• Instrument control
• Acquire data from each injection, together with injection number
from the auto-sampler and any chromatographic conditions.
• Process the acquired data first into peak areas or heights and
then into analyte amounts or concentrations.
• Store the resultant data files and other information acquired
during the run for reanalysis.
• Interface with other data or information systems for import of
data relating to CDS set-up or export of data for further
processing or collation of results.

Procedures required for computer systems
• Description of responsibilities: the roles and responsibilities of staff supporting the
computer system are defined.
• System description of hardware and change-control procedures: describes how the
hardware components will be maintained (equivalent to the hardware configuration log)
with the procedure to be adopted when the system configuration is changed.
• Preventative maintenance: describes the procedures for preventative maintenance of the
hardware components.
• Prevention, detection and correction of errors: the measures and procedures for finding,
recording and resolving errors in the system. This can be a complex SOP covering many
different aspects of the system and may refer to sections of the technical manuals
provided with the system. This SOP includes good housekeeping such as disk
defragmentation or monitoring the space available on all disks.
Procedures required for computer systems
• System boot and shutdown: this is a special SOP that should contain all the specific
instructions for starting up and shutting down the system. This SOP may be required in an
emergency and, therefore, should be well written and be easily available for use.
• Control of environmental conditions: For systems that require a controlled environment,
an SOP should define the acceptable ranges of temperature, humidity and power supply.
Other environmental considerations may be what to do in the situation of electrostatic
discharges, power surges, fire, lightning strikes or the use and maintenance of an
uninterruptable power supply (UPS).
• Contingency plans and emergency operation: this is a disaster-recovery plan and uses
alternative plans until the computer system has been recovered. It is important that any
disaster recovery plan is tested and verified before any disaster occurs.
• Back-up and restore of data: describes the procedures for back-up of data and software
programs and how to restore data to disk.
Procedures required for computer systems
• Security: the logical (software) and physical security of the system is covered with the
procedures for setting up and maintaining security.
• Installation and update of software: procedures to be undertaken before, during and after
installing software. This should start with the complete back-up of all disks and then
installation of the software and any testing and validation that may be required.
• Development and update of system software procedures: software can be written to
control the system or help execute functions. This SOP outlines the procedures for the
creation, documentation and modification of these procedures.
• Password policy
• Peak Integration procedure
Comparison of FDA and EU Regulations for Audit Trails
The audit trail regulatory requirements from 21
CFR 11 and EU GMP Annex 11 are compared and
contrasted.
In general, the two requirements are similar, but
interpretation is required, as some requirements
are present either in the underlying predicate rule
(for 21 CFR 11) or in other locations (for EU
GMP). It is important when interpreting a specific
section of a regulation to remember that other
parts of the regulations may modify or interact with
it.
The problem is that audit trails in commercial
applications fail to document the second person
review adequately and should highlight when
changes have been made to records.
Areas for ensuring CDS Data Integrity
1. Identify each user uniquely
2. Implement adequate password controls
3. Establish different user roles / access privileges
4. Establish and maintain a list of current and historical users
5. Control changes to the system
6. Use only trained staff to operate the system
7. Understand predicate rules for laboratory records
8. Define and document e-records for the system
9. Review the audit trails for each batch set
10. Back the system up regularly

[email protected] Letters - 2013
Failure to maintain laboratory control records with complete data derived from alltests conducted to ensure compliance with established specifications andstandards, including examinations and assays..
a. The inspection documented that HPLC processing methods (including integration
parameters) and re-integrations are executed without a pre-defined, scientifically valid
procedure.
Your analytical methods are not locked to ensure that the same integration parameters are
used on each analysis.
A QC operator interviewed during the inspection stated that integrations are performed and
re-performed until the chromatographic peaks are “good”, but was unable to provide an
explanation for the manner in which integration is performed.
Moreover, your firm does not have a procedure for the saving of processing methods used
for integration.
Reference : WL: 320-13-22 / Aarti Drugs Limited 7/30/13
Failure to maintain laboratory control records with complete data derived from alltests conducted to ensure compliance with established specifications andstandards, including examinations and assays..
c. During the review of the chromatography data, our investigator noticed that the raw data
retained does not include the run sequence or the processing method used to perform the
peak integrations.
Your QC personnel perform peak integrations based on analysts’ experience rather than by
an approved procedure.
Moreover, the chromatography raw data does not include the processing method used to
produce the final analytical results; therefore, during the review of the analytical data, it
would not be possible to detect any modification to the processing method.
Your firm’s response mentions that the QC operations are now under “direct control of
administrator”, but it does not define the roles and responsibilities of the administrator to
ensure the integrity and reliability of all QC laboratory data.
Reference : WL: 320-13-22 / Aarti Drugs Limited 7/30/13
Failure to maintain laboratory control records with complete data derived from alltests conducted to ensure compliance with established specifications andstandards, including examinations and assays..
d. The audit trail function for the chromatographic systems was disabled at the time of the
inspection; therefore, there is no record for the acquisition of data or modifications to
laboratory data.
Your response to this deficiency did not discuss how you will ensure that data audit trails
will not be disrupted in the future.
Reference : WL: 320-13-22 / Aarti Drugs Limited 7/30/13
Failure to implement access controls and audit trails for laboratorycomputer systems.
Your firm failed to have adequate procedures for the use of computerized systems used inthe QC laboratory.
At the time of the inspections, your QC laboratory personnel shared the same usernameand password for the operating systems and analytical software on each workstation in theQC laboratory.
In addition, no computer lock mechanism had been configured to prevent unauthorizedaccess to the operating system.
The investigator noticed that the current QC computer users are able to delete dataacquired.
In addition, the investigator found that there is no audit trail or trace in the operating systemto document deletions.
Reference : WL: 320-13-22 / Aarti Drugs Limited 7/30/13
Your firm failed to exercise appropriate controls over computer or related systems to assure that onlyauthorized personnel institute changes in master production and control records, or other records (21CFR 211.68(b)).
Your firm’s (b)(4) “Jasco LC-Net II” HPLC instruments do not have restrictions in place to
prevent any change or deletion of analytical raw data.
Additionally, there is no audit trail in place to determine any previous deletion of raw data.
Reference : WL: 320-13-26 / Agila Specialties Private Limited 9/9/13
Your laboratory control records do not include data derived from all of the tests necessary to establishcompliance with standards.
For example, the inspection found multiple raw data chromatograms in digital files labeled “test” and“demo,” that were injected prior to the sample injections that were used to conclude that batches were inconformance with the specification. They were:
a. A “demo” chromatogram injected 3/6/12 and the official organic impurities injection on 4/6/12for (b)(4)batch (b)(4).
b. A “demo” chromatogram injected 3/6/12 and the official organic impurities injection on 4/6/12for (b)(4)batch (b)(4).
c. A “test” chromatogram injected 12/9/08 and the official related substances injection on 12/10/08for (b)(4)batch (b)(4).
d. Two “test” chromatograms injected 12/4/08 and the official related substances injections on 12/5/08for(b)(4) batch (b)(4).
e. Five “trial” chromatograms injected 7/5/11 between the official related substances injections whichoccurred both before and after the “trial” injections for batch (b)(4) of (b)(4). The final injections weremade on 12/6/11 for this batch.
Reference : WL: 320-13-20 / Fresenius Kabi Oncology Ltd 7/1/13
Failure to protect computerized data from unauthorized access or changes.
Our inspection found that there were no restrictions to access the laboratory data residing on
the workstations attached to your standalone instrumentation: (b)(4) High Pressure Liquid
Chromatographs (HPLCs), the Fourier Transform Infrared Spectrophotometer (FTIR), the
gas chromatograph (GC) and the drives and portable media used as back-ups.
There was no protection of the data from alteration and deletion and no audit trails to detect if
such alteration or deletion had occurred.
Reference : WL: 320-13-23 / Posh Chemicals Private Limited 8/2/13
Your firm failed to ensure that laboratory records included complete data derived fromall tests necessary to assure compliance with established specifications andstandards (21 CFR 211.194(a)).
• For example, your firm did not retain any raw data related to sample weights and sample
solution preparations for the HPLC assays of (b)(4) tablet batches (b)(4) and (b)(4) that
you conducted on July 18, 2012.
• In addition, you did not include those results in the calculation of the final assay
values. Instead, you repeated the analysis the next day using a new set of sample
solutions, and reported the retest results on the certificates of analysis (COAs). Other
examples were also noted during the inspection.
Reference : WL: 320-13-17 / RPG Life Sciences Limited 5/28/13
Your firm failed to establish and exercise adequate controls over computers to prevent unauthorizedaccess or changes to electronic data.
• For example, the computers that control your analytical laboratory instruments, including
an HPLC, (b)(4) GCs, and an FTIR, lacked control mechanisms to prevent unauthorized
access to, changes to, or omission of data files.
a. Your analysis of (b)(4) USP batch (b)(4) exceeded the (b)(4) residual solvent limit on
February 29, 2012. Your firm did not report or investigate this OOS result, and deleted the
related electronic records. During our inspection, your analyst admitted that he also deleted
other uninvestigated failing and/or OOS electronic data from the laboratory database in
January 2013 prior to our inspection. Your QC Senior Manager also acknowledged this
laboratory-wide electronic data deletion practice.
b. During our inspection, your analysts demonstrated to our investigators that they could
delete any electronic analytical data files from the laboratory computers and external
backup hard drives.
Reference : WL: 320-13-17 / RPG Life Sciences Limited 5/28/13
Your firm failed to ensure that laboratory records included complete data derived from all testsnecessary to assure compliance with established specifications and standards (21 CFR 211.194(a)).
• For example, your firm’s laboratory records failed to include complete records of all stability testingperformed. The FDA investigators identified the practice of performing "trial" sample analysis forHigh Performance Liquid Chromatography (HPLC) analyses prior to collecting the “official” analyticaldata for stability testing. These “trials” were performed on multiple products,including (b)(4) Tablets (b)(4)mg, (b)(4)mg/(b)(4)ml, and (b)(4)Tablets. These trial runs were notrecorded in the equipment use log, and sample preparation data associated with these analyseswas destroyed, preventing any calculation or analysis of the resulting data. Your response statesthat trial runs were conducted using only one of the (b)(4) HPLC instruments located in the stabilitylaboratory, which happened to be the one instrument that the FDA investigators reviewed during theinspection. Your response indicates that you have revised procedures and re-trained your staff.
• Additionally, your quality control HPLC raw data files can be deleted from the hard drive using thecommon PC login used by all (b)(4) analysts. This deletion eliminates all records of sampleinjections and analyses. Your response indicates that this deletion function is only available on thesoftware used for one of (b)(4) sets of HPLC instruments. You also indicated that you have changedthe access control privileges such that laboratory analysts in a “user” role cannot delete or renamefiles.
Reference : WL: 320-13-21 / Wockhardt Limited 7/18/13
Your firm failed to record and justify any deviations from required laboratory control mechanisms (21CFR 211.160(a)).
The FDA investigators identified a memo dated March 12, 2013 (a week before the inspection),
documenting a computer “crash” that occurred on the central back-up and controller PC
for (b)(4) HPLC instruments. The memo describes the loss of instrument activity logs (audit
trails). Our investigators found that several of the HPLCs had the audit trail functions disabled;
therefore, there is no assurance that the data generated using these HPLCs is accurate.
Your response indicates that your firm performed an assessment of the historical HPLC
chromatograms (raw data) generated on each individual HPLC unit prior to March 12, 2013 and
verified it against previously printed chromatograms. Based on this analysis, your firm claimed that
you had confirmed that the backup data is available for each of the analyses and no analytical data
has been lost due to the computer crash. However, your firm failed to provide a risk assessment for
the products tested using the HPLC instruments that had the audit trail functions disabled. This is
especially noteworthy given the fact that prior to the inspection, at least one QC officer had the
ability to delete data on the affected system.
Reference : WL: 320-13-21 / Wockhardt Limited 7/18/13
Your firm failed to ensure that laboratory records included complete data derived from all testsnecessary to assure compliance with established specifications and standards (21 CFR 211.194(a)).
• For example, our investigators identified your practice of performing “trial” sample analysis for highperformance liquid chromatography (HPLC) analyses prior to acquiring the “official” analytical data forrelease and stability testing.
• The FDA investigators observed your practice of performing “trial” injections for HPLC analyses used totest content uniformity, assay, and dissolution for release and stability for at least (b)(4) different products.
• The investigator observed that for finished product (b)(4) Tablets (b)(4) mg, batches (b)(4), your firmperformed “trial” injections. The inspection documented that an HPLC run had an injection sequencenamed as (b)(4) assay,(b)(4) assay (b)(4), and (b)(4) assay (b)(4) attributed to the “trial” injections. Ourinvestigators noticed that the injection sequence names used the (b)(4) digits of the previouslyreferenced batch numbers. During the inspection, your firm’s management was unable to determinewhether the “trial” injections were performed using standard solutions or actual batch samples. Based onthe HPLC data, these “trial” injections occurred on 5/7/13. Later that same day, it appears that the“official” sample analyses were performed for batches (b)(4). The assigned names for the sequenceinjections creates the perception that your QC operator named the vials using the (b)(4)digits of the batchnumbers to link the “trial” injections for the batches with the official assay analyses. We are concernedbecause our investigator noticed that the “trial” injection data related to batch (b)(4) rendered an out-of-specification (OOS) result for the (b)(4) and (b)(4) assays. Therefore, it appears that the batch (b)(4) didnot pass the “trial” analysis but met specifications when the “official” sample was tested shortly thereafter.
Reference : WL: 320-14-01 / Wockhardt Limited 11/25/13
Your firm failed to ensure that laboratory records included complete data derived from all testsnecessary to assure compliance with established specifications and standards (21 CFR 211.194(a)).
• In addition, our investigator discovered that some of the “trial” injection data was not kept
on the HPLC hard drives because your firm deleted it. Your firm’s management confirmed
that the files were deleted as part of an internal audit.
• Our investigators found similar instances of the use of “trial” injections stored in default
folders on the HPLC hard drive for at least four drug products. The inspections
documented that both sites have SOPs that allow the use of “trial” injections. For example,
SOP QA/GLP/08 “HPLC Analysis” mentions that standard and sample injections are
allowed to ensure system equilibration before the system suitability runs are
performed. Neither the International Conference on Harmonisation of Technical
Requirements for Registration of Pharmaceuticals for Human Use (ICH) document Q2R,
“Validation of Analytical Procedure: Text and Methodology,” nor the United States
Pharmacopoeia General Chapter <1058> , “Analytical Instrument Qualification,” includes
instructions for performing “trial” injections for a method that is validated.
Reference : WL: 320-14-01 / Wockhardt Limited 11/25/13
Your firm failed to exercise appropriate controls over computer or related systems to assure that onlyauthorized personnel institute changes in master production and control records, or other records (21CFR 211.68(b)).
• The inspection documented that all of your QC laboratory computerized instruments ((b)(4) HPLCs)were found to be stand-alone, and laboratory personnel demonstrated that they can deleteelectronic raw data files from the local hard drive. Your firm deleted multiple HPLC data filesacquired in 2013 allegedly to clear up hard drive space without creating back-ups. Your QCmanagement confirmed that there is no audit trail or other traceability in the operating system todocument the deletion activity. Furthermore, your analysts do not have unique user names andpasswords for the computer and laboratory information systems; your QC analysts use a singleshared user identifier and password to access and manipulate multiple stand-alone systems.
• The (b)(4) HPLC systems in operation at the Waluj facility are also stand-alone, and during ourinspection, an employee demonstrated to the investigator that data can be deleted through the localhard drive of the data acquisition system. As with the Chikalthana facility, all Waluj facility employeesuse a shared password to access the operating system. During the inspection, your firm’smanagement informed our investigator that (b)(4) back-ups of data are performed. However, we areconcerned that your system and procedures permit deletion of HPLC files and that (b)(4) backed updata may not represent all the original data generated.

Your firm frequently performs “unofficial testing” of samples, disregards the results, and reports resultsfrom additional tests. For example, during stability testing, your firm tested a batch sample six timesand subsequently deleted this data
• Our investigators found your practice of performing initial “trial” sample high performance liquid
chromatography (HPLC) analyses prior to acquiring the “official” analyses. The “trial” sample results
were subsequently discarded. “Trial” HPLC analyses for (b)(4) USP ((b)(4)) were apparently run as
part of the 12-month long-term stability studies on batch #(b)(4) for related substances.
• The inspection revealed that on August 26, 2011, your employee ran an HPLC analysis sequence
with the sample names (b)(4) and subsequently deleted the raw data files. It was noted that the
assigned names for the sequence injections indicates that your quality control staff named the
samples using the last three digits of the batch numbers to link the "trial" injections for the batches
with the official assay analyses.
• Your Senior Quality Control (QC) Officer confirmed that these were analyses of batch
samples. Furthermore, we found that on August 27, 2011, this batch was analyzed for unknown
impurities and the results were reported to be within specifications. However, the chromatographic
data showed that the "trial" injection data for this batch failed the unknown impurities specification
of (b)(4)% in multiple cases.
Reference : WL: 320-14-08 / Sun Pharmaceutical Industries Limited - Karkhadi 5/7/14
Your firm frequently performs “unofficial testing” of samples, disregards the results, and reports resultsfrom additional tests. For example, during stability testing, your firm tested a batch sample six timesand subsequently deleted this data
• Similar unacceptable data handling practices were observed in your laboratory’s conduct of gas
chromatography (GC) analyses. The FDA investigators reviewed what appear to be data from
“unofficial” injections for GC analyses for recovered (b)(4) raw material batch #(b)(4). On February
11, 2012, your analyst performed testing on recovered (b)(4) raw material batch #(b)(4) and the
sample was within specifications. The following day, February 12, 2012, your analyst ran a GC
analysis sequence with the sample names (b)(4) and subsequently deleted the raw data files. Your
staff performed calculations during the inspection, at our request, that showed that these samples
did not meet the (b)(4) impurity specification for this material. Therefore, it appears that out-of-
specification data for batch #(b)(4) was considered to be “unofficial,” while passing data were
reported as the "official" results for the batch.
• In addition, the inspection revealed numerous examples of deleted GC electronic raw data files on
the computer controlling the GC instruments that were replaced with identical “official”
chromatogram file names. The identically named GC data files that were deleted had been created
at different times and contained disparate data. Also, it appeared that data was not consistently
archived to the central server.
Reference : WL: 320-14-08 / Sun Pharmaceutical Industries Limited - Karkhadi 5/7/14
Failure to maintain complete data derived from all testing and to ensure compliance with establishedspecifications and standards pertaining to data retention and management.
• Your firm did not retain complete raw data from testing performed to ensure the quality of your
APIs. Specifically, your firm deleted all electronic raw data supporting your high performance liquid
chromatography (HPLC) testing of all API products released to the U.S. market.
• In addition, your firm failed to retain basic chromatographic information such as injection sequence,
instrument method or integration method for the tests. Your firm’s lack of data control causes us to
question the reliability of your data.
• In addition, your laboratory management was unaware of, and therefore did not follow, the written
procedure detailing the review of analytical data.
• Furthermore, your management confirmed that the review of analytical data did not include
evaluating the system suitability parameters to ensure proper column performance.
Reference : WL: 320-14-10 / Trifarma S.p.A. 7/7/14
Failure to prevent unauthorized access or changes to data and to provide adequate controls to preventomission of data
• Your firm did not have proper controls in place to prevent the unauthorized manipulation of your
laboratory’s raw electronic data.
• Specifically, your laboratory systems did not have access controls to prevent deletion or alteration of
raw data.
• The inspection noted that all laboratory employees were granted full privileges to the computer
systems.
• In addition, prior to January 7, 2014, HPLC and gas chromatograph (GC) computer software lacked
active audit trail functions to record changes to data, including information on original results, the
identity of the person making the change, and the date of the change.
Reference : WL: 320-14-10 / Trifarma S.p.A. 7/7/14
Failure to manage laboratory systems with sufficient controls to ensure conformance to establishedspecifications and prevent omission of data.
• Our inspection revealed serious deficiencies related to your documentation practices, including
missing raw data. It is a basic responsibility of your quality unit to ensure that your firm retains the
supporting raw data that demonstrates your APIs meet specifications that they are purported to
possess.
• For example, during the inspection, our investigator found a chromatogram related to (b)(4), API in
the trash, dated October 15, 2013, which reported an additional chromatographic peak when
compared to the standard. During the inspection, your firm stated that the analyst discarded the
chromatogram because it was present in the blank injection. However, the analyst was unable to
retrieve the blank chromatogram from the system because it was overwritten by a subsequent
injection.
Reference : WL: 320-15-04 / Novacyl Wuxi Pharmaceutical Co., Ltd. 12/19/14
Failure to manage laboratory systems with sufficient controls to ensure conformance to establishedspecifications and prevent omission of data.
• In addition, the inspection documented that your firm made changes to integration parameters for the impurities
test without appropriate documentation or justification. Your firm relied upon hand written notes on a
chromatogram discovered in a drawer at the laboratory as the documentation for this change. Furthermore,
your firm implemented this change without an audit trail that would have captured the date of the change and
who made the change.
Other significant deficiencies noted in your laboratory system include:
a) Failure to have a written procedure for manual integration despite its prevalence.
b) Failure to use separate passwords for each analyst’s access to the laboratory systems.
c) Use of uncontrolled worksheets for raw analytical data in your laboratory.
d) Presence of many uncontrolled chromatograms, spreadsheets and notes of unknown origin found in a
drawer.
• The lack of controls on method performance and inadequate controls on the integrity of the data collected raise
questions as to the authenticity and reliability of your data and the quality of the APIs you produce.

• Determine the scope of the problem / Detect the integrity related to CDS
• Implement a corrective action plan (global) & Prevent the Integrity related to CDS
• Remove individuals responsible for problems from CGMP positions
• Complete a satisfactory inspection
GAP Analysis
• Perform GAP analysis by
brainstorming with cross
functional team to identify and
prevent the issues related to
CDS.

Summary of Data Integrity issues
• HPLC integration parameters were changed and re-run until passing
results were obtained
• Audit trail function was disabled.
• Unofficial testing of samples with file names like test, trial, or demo
• There are no controls to prohibit unauthorized changes to electronic
data / inadequate access controls.
• Files were saved on personal computers instead of a network
• Sharing passwords / unauthorized access.
• Lack of security on electronic data systems.
• Failure to maintain back-up of electronic data.

Detecting & Preventing CDS issues
• CDS should not be file based (easy to delete data), it should be with
an integrated database.
• Don’t use standalone workstations (easy to change date), use only
networked systems.
• Don’t use local workstation, acquire data on networked server.
• Restrict access to networked server except via CDS application.
• Follow the backup and recovery process.
• CDS application should be configured with full audit trails, Electronic
signatures, user types with access privileges.
• Document the complete software configuration.

Detecting & Preventing CDS issues
• Define a clear policy / procedure on various activities (e.g.
Password policy, Project creation & back-up)
• Have clear procedure and controls over the electronic data /
software administration.
• Cross check Privileges Vs. Job responsibilities.
• Check the adequacy of the procedures.

Detecting & Preventing CDS issues
• Strategic planning
• Determine the level of compliance that we are seeking
• Identify the weaknesses and strengths in our computerizedsystems
• Conduct an inventory of the systems
• Determine if the system must comply with Part 11
• Conduct the assessment using a checklist or spreadsheet
• Provide documented justification if certain system are exemptfrom Part 11
• Implement and execute a remediation plan
• Conduct the required follow-up as warranted.

Detecting & Preventing CDS issues
• Equilibrate chromatographic systems before they are ready for analysis.
• The time taken for equilibration shall be established during the method
development/validation/verification/transfer work performed in the laboratory and
this should be documented in the analytical procedure.
• Train the users and Follow good chromatographic practices and good start-up
procedures. Refer : http://www.slideshare.net/skvemula/good-chromatographic-
practices
• Follow proper change over procedures for mobile phase and modes (Normal
phase & Reverse phase).
• Inject the sample only after the system suitability criteria is met.
• Upon completion of the analysis, document the number of system evaluation
injections as part of the analytical report for the run.

Detecting & Preventing CDS issues
• Roles provide administrators with straight forward method for managing userprivileges.
• Administrator can define roles based on job responsibilities.
• User types / groups should be defined based on the structure of the laboratory.
• Have independent User ids for the computer systems and CDS.
• Users should not have privilege to delete / modify / overwrite the data.
• Audit trails for access (System audit trails) shall be checked frequently.
• Data security shall be maintained.

Conclusion
• A structured and systematic evaluation of current compliance state can go a long way to ensuring that your next CDS implementation is truly compliance-ready and maintains that compliant state.
• Lessons from past FDA warning letters
• Ensure that users are uniquely identified and that records of their access privileges are maintained.
• Have controls on re-integrations & methods.
• Understand the predicate rule in relation to computer systems
• Don’t delete / don’t give access privilege to delete raw data.
• Trial injections are not allowed.
• Stand alone systems are not allowed.
• Define electronic records and electronic working practices
• Review the CDS audit trails
• Vendors of CDS systems must ensure that audit trails are easy-to-use and actually contain information that is useful to the users to determine the quality and integrity of data.
