The University of Georgia
RESEARCH QUALITY CONTROL GUIDE
Michael E. Mispagel, Ph.D.
Office of Vice President for Research
August 24, 1998
The University of Georgia
is committed to its mission of teaching, research and service.
This institution
is known throughout the world as a strong research institution.
To maintain that reputation, it is imperative that UGA produce
the highest quality research possible, research that is above
reproach and which will stand on its own in any forum. The administration
of The University of Georgia is committed to that goal and
will
accept nothing less than high quality research that is reproducible,
well documented, and has the highest integrity. Toward that
end, this guide is submitted to better train our students, faculty
and
staff in the principles and practical applications necessary
to produce quality research.
The diversity of our research
is, of course, great. Many of the suggestions offered here may
not be appropriate for research conducted in some disciplines,
e.g. Fine Arts. Nonetheless, many of the principles expressed in
this document will cross over disciplines and be applicable regardless
of the research endeavor conducted.
This guide will not only
provide a standard of quality control for research at UGA, but
through the definition and pronunciation of high quality research
expectations, it is anticipated that adherence to the principles
espoused in this guide will foster an environment for that research
to flourish under common principles of quality.
Demonstration of high quality
research practices makes the University community more competitive
in the global marketplace both for faculty and staff competing
for research dollars, as well as for students seeking employment
after their academic and research training at The University of
Georgia.

Chapter 1
Quality Overview
There are many benefits of good quality control and quality assurance
to the researcher. Research by its nature is a very systematic process.
Inherent in that process is the care and organization needed to obtain
the desired results or to test a given hypothesis. Good documentation
of the steps taken, the procedures used, the equipment relied upon,
the observations taken will not only aid the researcher in the data
analysis, but will provide a high level of confidence that the data
were free of contamination by unknown variables, that the interpretation
of those data is accurate, precise, and complete, and that the effects
of unanticipated occurrences are minimized.
Without question, good documentation of a study benefits the researcher
during publication preparation. Complex studies require contributions
by many individuals. Without good organization and quality control
built into the system, the chance of unintentional errors occurring
increase, and the opportunity to misinterpret procedures, results or
observations increase. A systematic quality control program will minimize
those possibilities and will result in more defensible conclusions.
The competition for funding opportunities never seems to diminish.
Demonstration of high quality research practices will provide the researcher
with a competitive advantage over those who are unable to cite the
ability to comply with given standards, whether they be self-imposed
standards such as this guide, or federal mandates such the Good Laboratory
Practice regulations.
It is the duty of this institution to teach and train students for
entry into the marketplace. Oftentimes the standards imposed upon those
of us in academia do not equate well with those in industry. It is
incumbent upon us to prepare students to compete effectively in that
arena. One way to do that is to give our students an idea of the standards
of quality expected by industry and government in this country and
globally. Learning and practicing those standards here in the academic
environment will go far in enabling our students, post-docs, and technicians
to enter the non-academic work force well prepared to meet and exceed
the challenges ahead.
Oftentimes, research conducted at the University results in a product
or process which has patentable and marketing opportunities. Both federal
and international laws require specific and detailed documentation
of the development of the research conducted to produce the product
or process. The organization of a research program resulting from implementation
of a good quality control program will aid in meeting the requirements
to attain legal property rights through patent protection.
Ethical Standards in Academia
The academic community has always prided itself on its high ethical
standards in seeking truth through academic endeavors. In practice
our faculty train our students in ethical standards through formal
classes as well as by demonstrating ethics in their research and publication
practices. By maintaining a quality control program emphasizing good
documentation, explicit expectations and the acceptance of responsibility
for our research efforts, we are able to emphasize the need and the
practicality of high ethical standards for ourselves and our research
teams. These lessons in self-discipline and ethical standards will
carry over in all of life's endeavors and, thus, are appropriate to
the academic environment.
The "Cost" of
Quality
What is the "cost" of quality? Some would argue that "quality" is
inherent in the scientific process and is therefore inseparable from
it. Others would argue that extensive documentation suggested by a
quality program is only so much unnecessary, time-wasting paperwork.
Both arguments probably have valid points, but the question is better
asked in reverse. What is the cost of a lack of quality? Data which
may be unreliable because of the lack of training of some team members,
or because of uncalibrated, questionable equipment, or variable data-collection
techniques among staff may present the researcher with a data acceptance,
data interpretation, or even a publishing dilemma. Obviously, the discovery
of questionable data at any point in a research program can be costly.
It is always better, and cheaper, to design quality into a program
or research endeavor at the beginning to avoid the high cost of needless
repetition.
Standards Organizations
As trainers and educators of tomorrow's workforce, it behooves the
University community to appreciate the standards imposed upon industry,
both nationally and internationally, and to train our students such
that they are appropriately prepared to enter that job market. Quality
standards are imposed upon most industries and, in today's marketplace,
are critical to remain competitive.
The American National Standards Institute (ANSI),
the American Society for Testing and Materials (ASTM), the International
Standards Organization
(ISO), and the American Society of Quality Control (ASQC) are a few
of the agencies which develop standards. Such standards are used by
others to determine the qualifications of a laboratory for certification
or accreditation. Analytical laboratories conducting environmental
assays may soon be subject to certification through the EPA's National
Environmental Laboratory Accreditation Program (NELAP). Many international
corporations which produce a product or a service are now striving
to become AISO 9000" certified to remain competitive in the global
marketplace. The common variable among all the quality standards which
exist is the need for good documentation and an attempt to meet or
exceed the expectations of the customer. The University environment
is the place to learn those skills through involvement in high quality
research programs.
University Resources and Policies
The Research Policies & Procedures Handbook
available from the Office of the Vice President for Research (Phone
(706) 542-5969) describes
in detail the resources from that office available to the researcher
and delineates University policies relevant to the University's research
community.
The University of Georgia is committed to maintaining a safe work
environment for its students, faculty and staff. The University provides
numerous resources to attain that goal. It is incumbent upon the researcher
to familiarize him/herself with the laws applicable to their research
and research team. Appendix 1 lists offices which are prepared to assist
you with your research needs. A more detailed description of many of
these offices is in the above cited handbook. Often it is necessary
to obtain approval from one or more of the compliance offices before
grant proposals can be submitted or before funds can be released to
the researcher. Early contact with the compliance office staff to determine
a project's needs is suggested to avoid delay of project funding.
Technology Transfer and Patent Issues
The University of Georgia's Research Foundation,
Inc. (UGARF) assists researchers with intellectual property and technology
transfer. Chapter
II of the "Research Policies and Procedures Handbook" discusses
in detail the policies of the institution. UGARF should be contacted
(Phone (706) 542-5944) for additional detail about copyrights, patent
protection, licensing, and marketing an invention.
Clear and unambiguous documentation is critical
in obtaining a patent or marketing an invention. Most inventors do
not set out to simply
invent something from scratch. Inventions are usually "discovered" during
the course of other work. When that occurs, it is important to have
appropriate documentation practices in place to substantiate the claims
of the researcher. This section provides some information regarding
the documentation necessary for a successful patent application. Patent
law requires that an invention be new or novel, useful, and non-obvious.
The laboratory notebook is of extreme importance
to the individual wishing to obtain patent protection for an invention.
It provides 1)
the information needed to decide whether or not to apply for a patent;
2) the information needed to complete the application for the patent;
and 3) evidence of the invention's conception and when it was first
demonstrated. The invention's "conception" is when the invention
was first formulated in the mind of the inventor. "Reduction to
Practice" is the term used for the first experimental demonstration
providing the evidence that the invention works.
The notebook must answer the following questions: 1) What is the invention?
2) When was it made and where is the experiment recorded? 3) Has the
invention been disclosed publicly? 4) What is known about prior work
in the field? and 5) How complete are the data?
An "Invention Disclosure" includes
the following: Names and addresses of inventors, date of the conception
of the invention,
the date when a working model was demonstrated, a description of the
invention, an explanation of why the invention is novel, the uses of
the invention, a list of how and when the invention has been discussed
or shown to others. The notebook will contain the original notes and
data needed to substantiate the claims of the inventor by showing 1)
the date of the conception of the invention, 2) the continuity of the
record, 3) appropriate witnessing, 4) disclosures of the invention
to the public, and 5) speculation about the usefulness of the invention.
If the patent is challenged by another researcher
and becomes the subject of an interference proceeding, you will need
records to substantiate
the date of conception and evidence of your "diligence in reduction
to practice". That is, you must show that you worked continuously
on your invention and did not abandon it. If a lengthy period occurs
when no direct data entries will be made, you can show "diligence
in reduction to practice" by recording in your notebook, for example,
when you thought about the project, that you were waiting for samples,
that you were ill or on vacation, etc.
Have your laboratory notebook witnessed frequently.
A witness must be "a person skilled in the art to which it pertains..." and
must be able "to make and use the same." Witnesses must be
trustworthy, be willing to testify on your behalf and be available
for a few years. A witness cannot be a co-inventor. The witness must
be clear as to what is being witnessed, i.e. "Page read and understood", "Operation
of apparatus observed", "Material tested in my presence", "Samples
synthesized in my presence", etc. Do not simply write "Witnessed
by ___". Have witnesses record in their own notebooks that they
witnessed your work. A Patent Office publication emphasizes this point: "Your
priority right against anyone else who makes the same invention independently
cannot be sustained except by testimony of someone else who corroborates
your own testimony as to all important facts, such as conception of
the invention, diligence, and the success of any tests you may have
made."
If you disclose your invention to anyone else, note that fact in your
notebook and under what circumstances you disclosed your invention.
Note if someone else contributed an idea to your invention including
possible uses for the invention. If you submit a written description
to anyone such as a journal, note that fact in your notebook and keep
the correspondence. If your invention is orally presented in a seminar
or at a conference, note that too. If the invention is discussed at
a staff meeting, take your notebook to the meeting in order to make
notes directly.
Speculation is alright when you are suggesting novel uses for a new
invention. This is important because an invention must be useful in
order to be patentable, and because a new use for an established material
is patentable. Never suggest that it is not suitable for certain uses.
Specific recommendations from Roman Saliwanchik (1988, pages 20-22)
are shown below:
1. Use a bound laboratory notebook with numbered pages to record all
experiments.
2. Write the date that the work started in the upper right corner of the page.
3. Make all notebook entries in ink of a single color to facilitate proving
the content of the entry.
4. Fully describe the planned details of the experiment indicating the purpose
of the experiment and the expected results.
5. If some of the experimental work is done by another person, for example
an assayist, the data obtained from the assayist should be recorded in the
bound laboratory notebook as soon as they are received by the researcher who
submitted the material that was assayed.
6. Write the date that the assay results were received on the same page where
the results are recorded, and identify the assay date by reference to a prior
notebook page that contains a description of the material upon which an assay
was requested.
7. Make entries directly into the notebook as the experiment is carried out
and immediately when results are obtained.
8. If an incorrect entry is made, draw only a single line through the incorrect
entry; there should be no attempt to obliterate or erase the incorrect entry.
9. Enter all conclusions and observations about the experiment into the notebook;
even negative experimental results are important and, therefore, should be
included in writing in the notebook.
10. Immediately after each page of the notebook is completed, it should be
initialed and dated by the person actually doing the experiment; this person
may very well be a laboratory assistant.
11. Each page of the notebook should also be initialed and dated by the person
who supervised the person actually conducting the experiment.
12. The recording of the conclusion of an experiment should be followed immediately
by the signature of the experimenter; and a witness, i.e., a person who observed
and understood the experiment or a person to whom the experimenter disclosed
the experimental details and who understood the experiment, should sign thereafter.
13. If a notebook page is not completely filled out, a diagonal line should
be drawn through the blank portion.
Animal Care
The University is committed to the humane use of research animals
and complies with all state and federal laws pertaining to animal welfare
and protection including the Animal Welfare Act and the Guide for the
Care and Use of Laboratory Animals (NIH 1996). Portions of UGA's animal
facilities are accredited by the American Association for Accreditation
of Laboratory Animal Care (AAALAC). Researchers who use animals in
their programs must explain and justify their use of animals in an
Animal Use Proposal (AUP) which must be reviewed and approved by an
Attending Veterinarian and by the Institutional Animal Care and Use
Committee (IACUC) prior to the use of animals in a research program.
The AUP is valid for three years but must be reviewed annually. Any
modifications to the AUP must be approved by the IACUC. It is the goal
of the IACUC to assure that any pain or suffering to research animals
required for research is reduced or eliminated, and to assure that
the numbers of animals used in research projects are necessary.
The IACUC inspects the University's animal facilities twice a year
to assure that the facilities and the animal care meets the expected
standards. In addition, a USDA Veterinarian similarly inspects the
animal care program and the facilities at least once a year.
Investigators and technicians who will be responsible for the care
and use of research animals must have appropriate documented training
prior to their use of animals. Contact the Animal Care and Use Office
at (706) 542-5933 for additional information about obtaining this training.
Human Subjects
Similarly, the Human Subjects Office (Phone (706) 542-3199) tracks
and approves all student and faculty projects using humans as research
subjects. Federal law requires that appropriate informed consent be
obtained prior to initiating any studies using humans and that an Institutional
Review Board review and approve those projects prior to their start.
Biosafety
The Biosafety Office (Phone (706) 542-0112) will assist those researchers
who will work with pathological organisms or recombinant DNA/RNA. A
Memorandum of Understanding (MOU) will be completed after the facility
and project have been inspected and have met all federal and state
safety requirements regarding the organisms to be handled.
Quality Assurance
The Quality Assurance office (Phone (706) 542-5875) is in place to
assist University researchers produce the best quality data possible.
In particular, this office will train staff in the principles and application
of the federal Good Laboratory Practice regulations when those are
required by a sponsor. The QA office will also assist in the preparation
of a study protocol, writing of SOPs, facility inspections, as well
as data and final report audits. The QA office maintains a web page
related to quality assurance issues and documents at http://www.ovpr.uga.edu/qau/.

Chapter 2
Introduction to Quality objectives
This institution supports research of many kinds,
from many disciplines, and of extremely variable sophistication.
Keeping that in mind, it
is difficult to generalize too broadly about specific criteria common
to all. However, there are some guidelines which are applicable to,
at least, the disciplines which collect data of some kind for subsequent
analysis and eventual report. It is those types of research efforts
which will be most aided by these "research quality control guidelines".
For convenience, we will divide the discussion
of research expectations between two types of research. The first
is by far the most common
type of research conducted at the University. All research which is
NOT conducted under the mandate of the federally mandated Good Laboratory
Practice regulations would fall into this category. This would include
research conducted by students, postdoctoral associates, technicians,
and faculty under a "peer-review" modus operandi. Most would
agree that research conducted by students, though under the guidance
and training of a faculty member whether teacher or mentor, should
be conducted at the same level of quality as senior faculty whom they
should emulate.
The second type of research to be discussed in the next chapter is
that which falls under the mandate of the federal government's Good
Laboratory Practice regulations which is required for data being submitted
to a federal agency, usually the Food and Drug Administration [21 CFR
Part 58] or the Environmental Protection Agency [40 CFR Part 160],
that support or are intended to support applications for research or
marketing permits for products regulated by those agencies. However,
many other federal agencies now require compliance with these regulations.
The requirements for documentation are much more strict than you would
expect for basic research data submitted for peer review.

Assurance Homepage
Basic QC/QA requirements: Level 1
Grant Proposal Process: Preparation and Assistance
All research begins with a hypothesis or subject of interest usually
outlined in a grant proposal, study plan, or contract with a funding
agency or sponsor. Assistance with sources of funding and grant preparation
can be obtained from the Office for Sponsored Programs (Phone (706)
542-5939). Many facilities for grant preparation are available on line
at http://www.ovpr.uga.edu/sponprog/. Most applications for grants
are specific as to the information and format required.
At a minimum, the study plan should describe the proposed research
including a description of the organisms, subjects or materials to
be worked with, a justification for the study, the methods to be employed,
the observations to be made, the records to be kept, the statistics
to be used, and the responsibilities and obligations of the personnel
who will be involved in the study. The lack of a clear understanding
of the study and the duties of all individuals involved will inevitably
lead to misunderstandings which may compromise the integrity of the
study.
Study Documentation Types, Use of Forms, Paper
Trail Philosophy
The basis of all quality work is good documentation. Every study should
have an accepted method of documenting the activities, data, and findings
of the investigation. This documentation can be in the form of a laboratory/study
notebook or a binder of pre-printed forms specific to the study. Whatever
form they take, steps must be taken to assure that data is not lost
or misplaced and to be able to recognize that fact if it occurs, i.e.
a missing page number. Use of bound notebooks with pre-printed page
numbers works for many cases, as does paginating individual loose-leaf
forms which contain the study name or number and which are kept in
a binder. Clear identification of the owner of the material should
be conspicuous.
Given the fact that all scientific accomplishments should be reproducible,
researchers must develop the philosophy and practice of maintaining
a paper trail to permit the reconstruction of the study absent the
present investigator(s). Thus, the notes taken during an investigation
should be complete, clear, and unambiguous. Full equations with units
should be written in the notebook, rather on a piece of scrap paper.
Each step of a procedure should be recorded unless you are following
a written standard operating procedure which is referenced. Re-read
the section on the hints for maintaining a quality laboratory notebook
for patent protection.
Errors in data collection and recording are
common occurrences. Mistakes should be identified by a single line
through the error, and the researcher's
initials and date of change placed next to the correction to identify
the one making the correction and when it was done. You should never
obliterate an error, erase it, or use correction fluid to correct a
mistake since the "error" may need to be referenced at a
later time. It is always preferable to record all data in indelible
ink, rather than pencil.
Because it is not uncommon for data to be lost or destroyed inadvertantly,
copies of raw data should be made periodically and stored in another
location.
Personnel Qualifications/training
All employees of the University should have
a personnel file which documents the qualifications and training
attained for the job. Employees
should be comfortable in their knowledge of how to conduct a procedure,
use a piece of sophisticated equipment, or interact with a research
subject. Toward that end, it is useful for the employee to keep a list
of procedures (SOPs) to be performed, and equipment which is expected
to be used. Once "trained" in the procedures or the use of
the equipment through the use of the SOPs, the employee should be watched
performing the operation or procedure by the employee's supervisor.
Once both individuals are satisfied that the procedure has been learned
to the satisfaction of both, they can initial and date the document
to certify that proficiency has been attained. This simple document
then serves as documentation of training which will assure that both
the employee and the supervisor are comfortable with the skills mastered
before work begins. The potential embarrassment of a costly mistake
due to a lack of adequate training before data collection is thus avoided.
Implementation of training documentation should be made easier since
the Georgia Right-to-Know law already mandates that those state employees
handling or working with hazardous chemicals have documented training
on the handling, properties, and hazards associated with the chemicals
to which they may be exposed. Each campus unit has a Right-to-Know
Coordinator who oversees this program. Ask your department's safety
representative for detailed information regarding this program and
how it can help you develop your laboratory's training documentation.
Reagent, Solution, and Hazardous Chemical Labeling
and Storage
Label all reagent, solution, and hazardous chemical secondary containers
with at least the chemical name, concentration (if appropriate), date
prepared/opened, expiration date, and initials. State law requires
all hazardous chemical containers to have a hazardous chemical warning
label affixed unless it is intended only for short-term storage (one
week or less). This warning label must be either an NFPA or HMIS hazard
warning label indicating the health, flammability, reactivity, or other
hazard rating associated with the chemical. Such labels are available
from Central Research Stores.
All hazardous chemicals must be stored in well ventilated areas with
other chemicals which are compatible. Do not store chemicals alphabetically
except within a compatible class. Use appropriate storage cabinets,
such as flammable, acid, or corrosives, when appropriate. Do not use
non-explosion proof refrigerators or freezers to store volatile chemicals
such as solvents or ether.
Equipment Documentation, Calibration, Metrology
Just as you wouldn't knowingly publish false
data, neither should you accept data derived from an instrument which
has not been properly
calibrated and maintained. Blindly accepting data from an instrument
which you know little about can be foolhardy. Each piece of equipment
should have an associated log book for documenting any changes, maintenance,
or calibration conducted, including the date and the name of the person
doing the work. Without a written record such as this, there is no
way of knowing if the instrument will provide accurate data or if anything
was done to the instrument to alter its output. Electronic balances
should have their calibration checked daily, when in use, with standard
calibration weights to verify the instrument's reliability. A written
record of calibration checks assures the researchers using the equipment
that the data the equipment provides is accurate at that time. There
is no point in recording data from equipment which may provide questionable
data because of poor maintenance or a lack of proper calibration. The
researcher should always look for documentation which answers the question, "How
do you know it works?" before relying upon the data produced by
a piece of equipment.
Sample Labeling and Tracking
Lost or missing samples can be more than simply embarrassing. Their
loss could affect the outcome of a study. Care must be taken to label
all samples collected with the study name/number, the date, the collector's
name or initials, and a unique sample number. Prepare the sample labels
and attach them to the sample containers prior to sample collection
to save time and confusion.
Handling and Tracking of Testing, Reference
and Control Materials
Your test material, reference standards and control materials should
be handled with care and with a consideration of the possibility of
contamination. Good separation of these materials from each other and
from the collected samples will help to minimize this possibility.
When collecting samples which have been exposed to a range of concentrations,
collect the control samples first, followed by the lowest concentration
and proceeding to the highest concentration. Clean collecting equipment
between sample collections from different concentrations to avoid cross-contamination.
Standard Operating Procedures and Their Use
The use of written Standard Operating Procedures (SOPs) is strongly
encouraged to minimize the systematic errors associated with the collecting
of data by a number of people each of whom may do things in a slightly
different manner. SOPs should be written as a series of steps for the
successful conduct of a standard procedure. By following the SOP, steps
are not inadvertently left out, altered, or conducted in the wrong
order. Familiarity with the SOP will allow all the staff to do the
procedure in the same way thus minimizing the chance for error from
this source. As new techniques are developed or procedures are modified,
the SOP should be revised and updated while retaining the outdated
SOP in an historical archive so that you know how a procedure was done
at a previous time.
A typical SOP will have a title, SOP number, a stated purpose, and
the steps of the procedure in outline form. The lab supervisor or a
senior researcher and the author should sign-off on the SOP and indicate
the date when it is to be effective. SOPs should be written by the
people actually doing the procedures, rather than the senior staff,
because those individuals know best how a procedure is conducted. It
should be written in a practical fashion, without ambiguity or complexity
so that it can be used as a training document for new staff learning
the procedure.
Data Handling
Only trained and authorized people should be collecting data or recording
notes in a study notebook. The notebook should have a signature page
in front where everybody who will use that notebook can place their
signature, printed name, and initials so that initials on subsequent
pages can be associated with a complete, legible name.
To reduce the possibility of error in the notebook,
do not transcribe your data from scrap paper to the lab notebook.
Transcription errors
are very common but difficult to find. Always record your data directly
into the lab notebook. The first recording of the data is the Araw
data@ which will be used to reconstruct the study for data analysis
and publication purposes. The study notebook is not expected to be
without some grime and wear, especially if the study is a field study
or a study of long duration. It is much more important to have a study
free of transcription errors than to have a notebook free of smudges,
coffee stains, and corrected errors. Never throw away any "raw
data".
Use of Checks, Standards, Blanks, Spiked Samples
Most research investigations require the use
of a "control" group
or "untreated check" with which to compare the group receiving
the treatment. An analytical chemist will use known standards, blank
samples, and spiked or "fortified" samples to compare with
his unknown. The size of this control group will vary from field to
field, but generally one must consider the type of control samples
as well as the size or number of control samples to use as representative
of the control population. This is a statistical quality control problem
unique to each research project. Review the number, frequency, and
type of control samples, standards, field blanks, etc. before beginning
a research project. Consultation with a statistician in your field
prior to the start of the study may be appropriate.
Raw Data Ownership, Storage and Availability
Ownership of data collected as an employee of The University of Georgia
is subject to policies of The University as presented in Section IV-2
of the Research Policies and Procedures Handbook. Data rights applicable
to grants generally are dictated in a contract or granting guidelines.
UGA or UGARF hold copyright privileges to the presentation of scientific
data produced in the performance of duties as an employee of UGA.
Original data collected by a student for a student class project belongs
to the student. But data collected by a student being funded by a senior
investigator belong to that senior investigator. Students who are leaving
the University after conducting research should arrange to take copies
of their laboratory notebooks and/or data files while leaving the originals
in the possession of their major advisor unless other arrangements
are made. Generally, original copies of data should not be removed
from the University.
Keeping a second copy of research records in a secure place such as
with a major advisor/supervisor or even at home is recommended. Lost
or misplaced records or notebooks are not uncommon.
Original data should be stored in a dry, cool, secure area. The data
should be sufficiently labeled and identified by project name/number,
investigator(s) name, dates, etc. that access for subsequent reference
is possible.
There is no specific time limit for which general research data must
be archived. But, generally, it is prudent to maintain data for at
least five years after the material has been summarized and published.
Many investigators have a very difficult time ever disposing of research
data.

Chapter 3
Basic QC/QA Requirements: Level 2
There are other types of research conducted at The University of Georgia
which, by law, requires more stringent documentation. These are studies
which will support an application for a license or permit from a federal
regulatory agency such as the Food and Drug Administration (FDA) or
the Environmental Protection Agency (EPA). Historically, these studies
investigated the safety of a proposed product such as a drug, medical
device, pesticide, or food additive. Virtually all non-clinical data
submitted to these agencies must comply with the Good Laboratory Practice
Regulations as promulgated in the Code of Federal Regulations (FDA:
21 CFR Part 58, September 4, 1987; EPA: 40 CFR Part 160, August 17,
1989). You can access these documents at the UGA Quality Assurance
home page at http://www.ovpr.uga.edu/qau/.
These standards are recognized throughout the world in Memoranda of
Understanding between the U.S. and other major developed countries
as representing the minimum documentation required to assure the integrity
of the data to the regulatory agencies as well as to the consumer.
Because of the widespread use and acceptance of the Good Laboratory
Practices (GLPs) in industry, many other federal funding agencies also
require adherence to these standards including the U.S. Forest Service,
USDA, Soil Conservation Service, and others. In addition, clinical
trials of drugs must comply with a similar set of regulations called
the Good Clinical Practices, and, once a product is developed and approved
for manufacturing, that process must comply with the current Good Manufacturing
Practice regulations. All of these regulations are mandated and enforced
so as to assure the public of the safety, consistency, and efficacy
of the products they are consuming. In addition, they are in place
to minimize the potential for systematic error in the generation and
collection of data and to reduce the possibility of scientific fraud.
Our brief discussion of these principles here is not only for those
who will actually conduct such studies at this institution and thus,
must comply with the letter of the law. Those individual research teams
will receive detailed training in the GLPs and close scrutiny of their
facilities, personnel, and studies throughout the research. This chapter
is intended more for those who do not need to comply, but who would
like a higher goal or standard of quality research to attain. A great
deal of what is in these regulations is also good common sense, and,
not coincidentally, good science. And, lastly, our discussion of these
principles is to help train those students who will compete in the
industrial job market so that they will be prepared to conduct research
according to the mandates of quality research imposed upon them.
Introduction to the GLP Mind-set
All of the principles of study conduct and quality control for research
studies discussed above pertain to a GLP study as well. But, in some
areas, more stringency and organization is required and forced upon
the researchers. First, the data has a different purpose and review
process for GLP studies. Data generated from GLP studies are generally
compiled by a sponsor such as a drug company and are eventually submitted
as part of a registration package to a federal agency. Those data will
be reviewed by federal auditors and eventually a decision will be made
as to the adequacy of the data and whether or not registration should
be granted. This process may take many years during which staff personnel
from the original studies will probably have turned over many times.
Those who review the study material will be attempting to reconstruct
the study many years after the work was done using the data records
alone. Those individuals are also trained to be skeptical about claims
of efficacy and must search for adverse reactions to the test materials
to protect the public and the environment. Thus the burden of proof
and clarity of documentation is the responsibility of the original
investigative team.
This differs significantly from the data generated
from typical academic research pursuits which generally are reviewed
as summary data in a
manuscript through the peer-reviewed publication process. The research
may be the same, but the mental discipline required for documenting
that research is not. The change in mind-set required for GLP investigations
asks the researchers to continuously question themselves and the system
in which they are working and to produce the documentation to answer
the most common question, "How do I know?". It requires the
researchers to assume the worst of their data, their staff, their equipment,
etc. unless and until their documentation proves otherwise. Considering
that there may be a legal challenge to their data someday, that philosophy
seems prudent.
Study Management and Facility Management
A research project in academia may have a number of co-Principal Investigators,
each receiving some credit for the grant and each assuming variable
responsibilities for the project. A GLP project may have similar co-PI's,
too, but in addition one of the PIs must be the single designated Study
Director. The Study Director is the one individual responsible for
the overall conduct of the non-clinical laboratory study and is the
single point of study control. The study director (FDA '58.33) shall
assure that:
a) The protocol, including any change, is approved and followed;
b) All experimental data, including observations or unanticipated responses
to the test system are accurately recorded and verified;
c) Unforeseen circumstances that may affect the quality and integrity of the
nonclinical laboratory study are noted when they occur, and corrective action
is taken and documented;
d) Test systems are as specified in the protocol;
e) All applicable good laboratory practice regulations are followed;
f) All raw data, documentation, protocols, specimens, and final reports are
transferred to the archives during or at the close of the study.
The Study Director will sign a compliance statement in the final report
stating exactly where the study practices differed from the GLP regulations
(EPA '160.12).
In addition, the testing facility management have specific responsibilities
(EPA '160.31) including:
a. Designate a study director as described in '160.33 before the study
is initiated.
b. Replace the study director promptly if it becomes necessary to do so during
the conduct of a study.
c. Assure that there is a quality assurance unit as described in '160.35.
d. Assure that test, control, and reference substances or mixtures have been
appropriately tested for identity, strength, purity, stability, and uniformity,
as applicable.
e. Assure that personnel, resources facilities, equipment, materials and methodologies
are available as scheduled.
f. Assure that personnel clearly understand the functions they are to perform.
g. Assure that any deviation from these regulations reported by the quality
assurance unit are communicated to the study director and corrective actions
are taken and documented.
The Quality Assurance Unit will submit inspection findings to management
and the study director for their information and response, if needed.
In industry it is easy to identify the testing facility management.
In academia, it is often not very clear who should be responsible for
these duties; it might be a department head, dean, director, or an
associate vice president. Such a determination of who will assume this
role should be made early in the project development stage such as
during protocol development.
Protocol Development and Amending
Every GLP study must have a written, approved protocol. A protocol
differs from a grant proposal in that the protocol does not need to
justify the project since it is not intended to be a fund-raising tool.
Rather, it shall indicate the objectives of the study, identify the
testing facility and indicate the responsible parties, describe the
test system, the experimental design, the observations to be made,
the records to be maintained, the statistics to be used, etc. A protocol
checklist is available in the Appendix. The protocol must be approved
by the sponsor and dated and signed by the study director. Any deviation
from the protocol must be documented with justification given, and
signed and dated by the study director.
Study Documentation Requirements and Error Corrections
Data collected for GLP studies must be recorded promptly and legibly
in ink. All data entries should be dated on the day of entry and signed
or initialed by the person entering the data.
There will probably be a number of study files which contain numerous
documents pertaining to the study. These files may contain telephone
memos, correspondence, shipping labels, organizational charts for your
unit, internal memos, quality assurance findings. You may, for example,
have files of equipment maintenance/calibration records, SOPs, environmental/weather
data, training records, animal room logs, veterinary care reports,
pathology reports, analytical lab reports, statistical analysis data,
purchase orders, protocol amendments, protocol deviations, unusual
occurrences, chain-of-custody records, manifests, interview records,
etc. All of these documents must be archived at the end of the study
so that the sponsor and the regulatory agencies can reconstruct the
study to understand exactly what transpired during the course of the
investigation and to understand completely the procedures undertaken,
the quality control employed, the integrity of the data collected,
and the validity of the results and the conclusions of the study. Needless
to say, disorganized or illegible data files will leave a negative
impression on those reviewing the data. Thus, the GLP mind set can
force a research team to be organized and cautious prior to data collection.
Of course, errors in data entry do occur. Changes or corrections to
the data shall be made so as not to obscure the original entry, shall
indicate the reason for the change, and shall be dated and signed at
the time of the change (EPA '160.130(e)). It is common to use circled
code numbers to indicate the reason for a change in a data entry such
as the following:
1. Misspelling or carelessness.
2. Instrument was misread.
3. Misunderstood or heard incorrectly.
4. Miscount.
5. Recorded in wrong place.
6. Transposed or out of proper sequence.
7. Illegible.
8. Wrong word or phrase for meaning.
9. Previous error(s).
10. Other unlisted reason. Identify reason for change.
Other error code systems use two-letter codes,
such as "WE" for "Wrong
Entry", or "WD" for "Wrong Date". Such codes
may be easier to remember if there are not too many of them.
Computer and Software Validation and Use
For many researchers, computer use is integral
to their programs for collecting, tabulating, manipulating, calculating,
and reporting their
data. To ensure "a high standard of quality for computer-resident
data produced in support of EPA programs", that agency published
on August 10, 1995 the "Good Automated Laboratory Practices (GALP):
Principles and Guidance to Regulations for Ensuring Data Integrity
in Automated Laboratory Operations". The concern of the agency
is that too much faith might be put into electronic systems such as "laboratory
information management systems" (LIMS). However, not all automated
laboratory systems are LIMS. Automated laboratory systems that record
data but do not allow changes to the data are not LIMS. The ability
to effect changes to original observations or measurements prior to
the recording of that data is the factor in determining whether the
automated laboratory system is a LIMS and therefore subject to the
GALPs.
.
The GALP discusses in detail how to document the validation of the automated
data collection system through the use of SOPs on maintaining the security
of the system, data entry, verification of input data, data changes, data analysis,
processing, storage and retrieval, backup and recovery of data, maintenance
of data collection system hardware, and electronic reporting.
Software validation must be conducted according to an SOP to describe
what the software is expected to do or the functional requirements
that the system is designed to fulfill. All algorithms or formulas
used must be listed, and a description of acceptance testing criteria
must be written.
All GLP provisions regarding personnel training, data entry, raw data,
records and archives pertain as well to automated data collection systems.
Thus documented evidence must be available to prove that the personnel
are qualified to use the system, that the hardware is adequate for
the job, that the software does what it is supposed to do, that adequate
security is in place to protect the data, and that all the records
are available for audit.
The GALP Guidance document discusses in detail six principles which
are inherent in both the implementation of the GALP and its data management
policies (pp. 2-1 - 2-2).
1. DATA: Laboratory management must provide a method of assuring the
integrity of all LIMS data. Communication, transfer, manipulation,
and the storage/recall process all offer potential for data corruption.
The demonstration of control necessitates the collection of evidence
to prove that the system provides reasonable protection against data
corruption.
2. FORMULAE: The formulas and decision algorithms employed by the
LIMS must be accurate and appropriate. Users cannot assume that the
test or decision criteria are correct; those formulas must be inspected
and verified.
3. AUDIT: A critical control element is the capability to track LIMS
Raw Data entry, modification, and recording to the responsible person.
The capability utilizes a password system or equivalent to identify
the time, date, and person or persons entering, modifying, or recording
data.
4. CHANGE: Consistent and appropriate change controls,
capable of tracking the LIMS operations and software, are a vital element
in the
control process. All software changes should follow carefully planned
procedures, be properly documented, and when appropriate include acceptance
testing.
5. STANDARD OPERATING PROCEDURES (SOPs): Procedures
must be established and documented for all users to follow. Control
of even
the most carefully designed
and implemented LIMS will be thwarted if the user does not follow these procedures.
This principle implies the development of clear directions and Standard Operating
Procedures (SOPs), the training of all users, and the availability of appropriate
user support documentation.
6. DISASTER: The risk of LIMS failure requires that procedures be
established and documented to minimize and manage their occurrence.
Where appropriate, redundant systems must be installed and periodic
system backups must be performed at a frequency consistent with the
consequences of the loss of information resulting from a failure. The
principle of control must extend to planning for reasonable unusual
events and system stresses.
Quality Assurance Unit
The Quality Assurance Unit (QAU) must be separate from and independent
of the personnel engaged in the study (EPA '160.35). The role of the
QAU is to assure management that the facilities, equipment, personnel,
methods, practices, records, and control are compliant with the GLP
regulations. The QAU must maintain a master schedule of ongoing studies
and protocols of those studies. The QAU inspects each study at intervals
adequate to ensure the integrity of the study and keeps records of
those inspections, reports the finding of those inspections to the
Study Director and management, and reviews the final study report Ato
assure that such report accurately describes the methods and standard
operating procedures, and that the reported results accurately reflect
the raw data of the study@. The Quality Assurance Unit will also prepare
and sign a statement in the final report specifying only the dates
that inspections were made and the dates that the findings were reported
to management and to the Study Director.
The QAU should be viewed as an independent member of the research
team whose goal is to aid the research team to produce the most accurate
and defensible product possible within the constraints of the GLPs.
Data Storage and Retrieval, Archiving, Raw Data
Availability
It may take many years for a company to compile and submit a regulatory
package of completed studies in support of an application. Thus, data
storage and retrieval are important. AAll raw data, documentation,
records, protocols, specimens, and final reports generated as a result
of a study shall be retained. Specimens obtained from mutagenicity
tests, specimens of soil, water, and plants, and wet specimens of blood,
urine, feces, and biological fluids, do not need to be retained after
quality assurance verification {' 160.190}.@ Many companies use a commercial
archive facility to handle this task. Records must be retained 1) as
long as the sponsor holds any research or marketing permit to which
the study is pertinent, or 2) at least two years after the completion
of the study if it is not submitted to the agency, or 3) at least five
years following the date on which the results of the study are submitted
to the agency in support of an application for a research or marketing
permit.
