The administrator is responsible for managing the relationship with ControlLab, keeping the registration data up to date, managing and delegating tasks to the Online System, receiving and distributing materials and correspondence, ensuring deadlines and analyzing results.
One of the main tasks is to promote the dissemination of information, starting with the purpose, operating rules and evaluation criteria of the PT. For this, it is important to ensure that all laboratory stakeholders read and understand the Gibi Quality Control information, the Participant Manual and the "Questions and Answers" available on the site.
To manage the day-to-day of the program there are the warning emails and the homepage of the Online System, which describes the rounds in progress with the deadline for reporting results and recently published evaluations.
For the monitoring the evaluations, there is the management report and the general accumulation. It is important to conduct a critical analysis of the results together with those involved and analyze the causes for inappropriate results immediately, based on the evaluation report, results profile and internal documents/records. To help you in this step there is the "Diary of Proficiency", available in print format and use in the Online System (Education).
A new user always has doubts about the operation of the service and its responsibilities. For this reason, the first orientation is to read the Participant Manual, which explains how the program works, and the "Questions and Answers", which clarify the participants' most common doubts.
The main care is to run the control correctly so that the evaluation represents exclusively the performance of the routine and so that it is not contaminated with errors related to the quality control itself.
The main precautions include:
1. Read and follow the instructions for using the materials to avoid misunderstandings in the handling, since there are some procedures that differ from those adopted in routine patients;
2. Reconstitute freeze dried material with reagent water and with calibrated pipettor support, paying attention to the volume indicated on the label, since each material has a specific volume and errors in this step cause damage to the evaluation;
3. Use reconstituted material immediately to avoid variations resulting from improper storage;
4. Give special attention to dilutions and consequent calculations to avoid reporting erroneous results;
5. Check the need to convert results to the unit adopted by the program and perform the conversion correctly (see "Why do I have to convert my results to the unit adopted in the PT?");
6. Identify the analytical system correctly (reagent, method, equipment, etc.) and report all requested information. According to the test, the absence of a data referring to the methodology may make its evaluation unfeasible;
7. Be aware of the response deadline and e-mail warnings (see "What happens when I stop responding to a round?");
8. Contact Controllab immediately if you have any questions.
Although the modules are quarterly, participants with monthly payments split the amount. Thus, the invoice describes all the modules in which the participant is enrolled, and is charged the amount corresponding to the monthly apportionment. This is done so that the laboratory has a value for payment always equal, with greater ease of control.
It's simple! Just do not answer. As the PT (proficiency testing) modules are composed of test groups, it is expected that one test or another will not be part of the participant's routine. In this case, it is enough to never report any results, and this essay simply will not count points in your evaluation.
If you outsource, do the same. Do not submit results that were not obtained by your laboratory, or otherwise will appear on your evaluation and certificate as if it had been performed by your laboratory.
Each participant should only report results obtained in his routine, should not report tests performed by third parties or other technical unit of the laboratory. Just as you should not exchange information with other laboratories. This is because:
1. The objective of participating in the program is to have the opportunity to identify the good progress or not of each participant processes. When the results are obtained by another, there is no benefit.
2. When duplicating the result of a single laboratory, a trend is inserted in the result group that is not real, which may prejudice the statistical analysis and the evaluation of the other participants. The statistical model adopted presupposes only one result of each participant, which individually contributes to the determination of the target value used for the calculation of the evaluation range.
3. The certificate of proficiency and other documents proving participation in the program are issued to the enrollee in the program, which means that all the tests and results are executed by the enrollee.
The modules of the PT (proficiency testing) are quarterly to meet statistical requirements and ANVISA/REBLAS. The purpose of the proficiency testing is to identify errors, especially systemic ones. However, it is only possible to conclude whether an error is systemic (repetitive) or random, when at least two different items are tested.
With this, the first prerequisite is: never send a single sample per round. If we chose to submit monthly, we would have at least 24 items per year for each trial/module, and this would make the program much more costly.
On the other hand, there are no effective gains that justify such frequency and quantity of materials. Globally, 10 to 20 test items are adopted, with a common periodicity of 2 to 4 months.
But this rule presupposes that the laboratory adopt effective internal controls with more frequency in its routine (daily, between batches etc). Do not change internal control with external control. The first one is to verify its reproducibility and small deviations; already the proficiency test is mainly directed towards accuracy.
For more details read the article “Multiple Materials for Systematic Error Monitoring in Proficiency Testing”.
The rounds are sent according to the annual calendar, previously defined and distributed to the participants. The rounds are usually sent in the first half of the month, with some adaptations for the current year and holidays. Therefore, it is necessary the annual calendar available on the internet (website and online system).
Users of the Online System also receive an email notification of the round referral.
Not necessarily. Each module has its materials (test items), which can be:
• unique to more than one module (such as Biochemistry and Basic Hormones: all tests are dosed on the same item);
• unique for all tests of a module (as in Tumor Markers: an item for analyzing all markers);
• Individuals per test (as in Molecular Biology: one item for each type of test - HBV, HCV, and HIV);
• Different for test groups (such as in Cell Count: one material for global counting and one for differential);
• Items are labeled with an individual identification (e.g. BA01), and response forms (printed or online) repeat this identification for the tests to which the item corresponds.
This distribution is always the same and repeated every round, so that the participant becomes familiar with the system. Any change is communicated to the participants.
In order to make a statistical study and compare its results with those of the other participants of the PT (proficiency testing), it is necessary to adopt a single unit of measurement. Thus, we always seek to adopt the unit most used in the market.
To compare the results of different participants and to promote statistical calculations, it is necessary to set a default number of decimal places. Thus, a number of decimal places are chosen and/or relevant for the analysis of results.
The parameters calculated manually from multiple systems (using other parameters not directly related to the analysis at issue) are evaluated in an educational way in the program. These parameters do not present values obtained directly from the dosages, accumulate uncertainties due to the different variability contributions of the raw results and do not have the reliability required for an evaluation.
For more details read the “Limitations of Results Obtained Indirectly (calculation) reported in Proficiency Testing”.
This "non-achievement - Na" account for your PT (proficiency testing) assessment and must be recovered at the end of the period with the special round. But attention! For tests that are not performed in their routine, the process is different. See the answer to "How should I proceed with tests that I do not perform/outsource."
The rounds are quarterly and have a reduced number of test items (when compared to the volume of patients attended by the laboratory). Therefore, it is very important that the laboratory responds to all the rounds and tests of your routine.
A non-participation is only paid when the laboratory has stopped activities, such as instrument breaking. In this case, it is necessary to justify as soon as possible to Controllab. This allowance can only occur once a year, to maintain the annual representativeness of its results. See the answer to "If you cannot answer for lack of kits or broken equipment, what happens?".
If, during the whole run-in period, the laboratory is stopped for operational problems (such as stopped equipment or lack of kit), the laboratory should contact Controllab and send a document proving their situation, such as the report or repair guide of the equipment in the period.
Thus, Controllab can discount this round of laboratory scores. However, this procedure may not occur more than once a year, since the sampling of the proficiency testing would no longer be representative for the certificate.
The evaluations today are released within two to ten business days after the deadline for sending results. New policies are being studied and implemented at all times, to increasingly reduce this evaluation period.
The evaluation process includes (1) receipt of the results, (2) statistical and technical analysis, (3) customer feedback analysis and (4) generation / access to evaluations.
In receipt of results, we are increasingly restricting the granting of increased response time to minimize the impact on the release of evaluations. In the analysis phase, the process has been optimized without giving up the analysis of qualified professionals and consulting the advisors in addition to the statistical treatment. These policies are to ensure a more thorough analysis and more reliable evaluations.
Customer feedback analysis occurs simultaneously with the statistical and technical analysis of the data and must be done completely for the release of the evaluation, since it may contain important information to define the evaluation. However, the volume of comments grows every day (ten to twenty times greater than when implementing the online system), with different information (see 'When I comment on response forms do you respond?') and often requires a lot of time in the evaluation process. Actions for the best use of the 'feedback' field and reduction of frequent questions have been adopted to minimize this impact.
The generation and access of the evaluation are already immediate since 2004. Once released, it is available to consultation in the Online System.
A delay in the evaluation is usually associated with some atypical performance in the data that requires a more complex analysis, such as material reanalysis (material quality control), contact with users / manufacturers or conducting research and consultation with third parties (other advisors).
Quality control materials are previously analyzed. They go through a quality control that aims to approve them regarding homogeneity and stability. Meanwhile, the evaluation of the participants' results is the statistical model most used by the proficiency testing providers. This is because it has a consistent volume of results to evaluate accuracy and allows its comparison in a similar analytical system, since the control made by the provider does not cover all existing analytical systems.
However, it is important to note that a comparison is made between participants' results and quality control to release an evaluation. Controllab always seeks consistency of these results so that there are no mistaken evaluations.
A result may not be evaluated because:
(a) didn't form an evaluation group (less than 5 results);
(b) the evaluation group presented high variation;
(c) by determination of the advisory group, this decision is described in the document "Results Profile".
In some specific situations, it is possible the evaluation in groups with less than 5 results, as statistical consistency of the data is verified.
There are a few possibilities:
1. Test with high variation: the results of the participants do not form a consistent statistic, presenting high variation. The option is to not evaluate based on this data.
2. Tests with predictable results: some analytes are only available (human matrix etc) in normal concentrations, and it is not possible to change them synthetically. In this case, they do not meet the requirement of proficiency test of "materials with unknown results" and no evaluation is done.
3. Insufficient number of evaluations: 8 to 16 items per year are sent according to the test, if more than 50% of the tests have not been evaluated (see the question "Why sometimes my results are not evaluated?"), the option is to not evaluate because the volume of evaluations is not representative for the year.
The certificate lists all tests with performance higher than or equal to that defined by ANVISA, in procedure GGLAS 02/43. We define these tests as "adequate" because they have reached the minimum acceptable level of performance.
The certificate also presents educational tests (see 'Why are some tests classified as EDU?'). Inadequate tests, with less than acceptable performance, is not listed on the certificate. The "Management Report", available for consultation in the Online System, maintains an updated list of inadequate tests.
The daily reconstitution of the IC (internal control) avoids the propagation of reconstitution errors and allows stability with less dependence of the storage conditions. Therefore, reconstituting daily, without dividing into aliquots is the best way to use it.
After opening and reconstitution, the control material is subject to variations and contamination, in the same way as patient materials. Thus, the user who chooses aliquot must be very careful with the reconstitution and storage of the material.
The use of two levels of control has already been proposed in GCLP - Good Clinical Laboratory Practices, CLIA'88 (American law) and in accreditation processes. This is because studies point to a greater efficiency of the process of control with multiple levels that allow greater process traceability and greater coverage of the measuring range.
The use of only one level of control basically requires rejection when a control result exceeds 2DP, for example. This leads to 5% false rejections for 1 daily reading, 10% for 2 daily readings, and so on. And every false rejection generates rework, costs, and does not help to know better the process nor to improve it.
O próprio Westgard disponibiliza um software que é capaz de fazer simulações estatísticas e definir a melhor combinação de níveis, freqüência e regras de controle para cada ensaio. Lembrando que, para alguns ensaios, a quantidade de níveis recomendada é superior a 2.
Assim, os fabricantes costumam disponibilizar seus controles com a quantidade de níveis mais apropriada para a amplitude da faixa de medição e de acordo com as características da metodologia empregada.
The laboratory indicators are essential elements in the practice of measurement of management and process performance, allowing a comparative evaluation, at a national and international level, of the results of the clinical laboratories in front of their peers and market leaders.
This process of benchmarking of practices and metrics, also known as Benchmarking, allows laboratories to be more effective in decision-making against their strategies and encourages the continuous improvement of their processes, contributing to patient safety and to increasing productivity and sustainability of the laboratory medicine sector.
A new user should first read the tab "Instructions" of the Indicator Spreadsheet and understand it. It is important to select the data for which the laboratory has information (Data Entry tab), then to check which indicators these data have been contemplated (Indicators tab) and focus on them while verifying the systematics that should be adopted in the laboratory to obtain the others data.
In order for the indicators to contribute to improving the quality of health care, it is necessary that laboratory staff involved in the monitored processes have access to data specifications and how they should be collected, especially in the critical aspects of the laboratory process.
If you have any questions, you should contact Controllab.
The discussion group is a group of volunteers from a number of different laboratories and is responsible for defining and detailing the indicators, analyzing overall results, clarifying questions and proposing improvements to the program.
Yes. The data is analyzed as a whole without verification from the laboratory that sent us and, for greater security, the laboratories are given an access number so that their name is not exposed in any material. All data available for other laboratories are general data.
In "My Networks" the user can create their own comparison network for a closed benchmarking. In this tool, he may invite support networks or brand labs to compare their performance with each other.
For the comparison to be generated, network members must respond within the reporting period of the indicators. The member who does not respond to the indicator will not have access to the comparison.
To create a comparison network, the Laboratory Indicator Benchmarking Program participant must access the option â€œMy Networksâ€ (Online System> Indicators Benchmarking> My Networks> Create New Network).
To invite other labs you will need the name of the institution, the name of the person in charge and the contact email. Once the information is completed and the network has been created, all invited members will receive an activation code to confirm acceptance in the registered emails.
Invited members will receive an activation code in their registered emails. This code must be entered in the Online System > Control Center > My Networks > Enter Code. Once the code is entered and the action confirmed, this user will be a member of the network.
The invited laboratory not participating in the Indicators Benchmarking Program should contact our Call Center (+55 21 3891-9900 - firstname.lastname@example.org).
Any laboratory participating in the Controllab Laboratory Benchmarking Program. However, the invitation may only be sent and accepted by the user registered as an "administrator" profile in the Online System.
The network is active only when all invited members accept the invitation. If any invitations are still pending, the network status will also be pending. In this case, the institution responsible for the created network may resend the invitation or delete this member. Once the network is activated, the comparison will be generated within the same period as the Program benchmarking release (on the first day of each month).
There are 3 identification options:
During the creation of the network, the user must choose one of these options and, in the invitation to the laboratories, the identification option configured by the responsible institution will be displayed.
Only the institution responsible for the network (institution you created from the comparison network) can manage. However, any member of the group (with the profile "administrator" in the Online System) can leave your comparison network at any time.
From the exclusion date, the indicators will no longer be compared between network members. Once the group is deleted, it cannot be reactivated.
No. The calibration is a measurement process that informs the actual volume dispensed or contained by a glassware, the actual measurement of a thermometer in relation to that indicated in its graduation etc. In short, it is an "x-ray" of the instrument's current functioning.
As a result of the calibration, it is possible to decide whether the instrument is suitable for use. Some instruments, when presented with deviation from the expected (error), can be adjusted, provided that the cost of the repair justifies and has mechanisms for the adjustment.
It is up to the user to define the maximum permissible error for the maintenance company to make the adjustment. After adjustment, a new calibration is necessary to check its effectiveness.
There is no "validity" previously defined for a calibration certificate. The user is the one who should define the interval between calibrations to be adopted for each instrument, considering its frequency of use and the results obtained in the last calibrations.
Initially, when there is no instrument history, the use of short deadlines is recommended. This prevents an instrument out of the right conditions impacting a large volume of results for a long time, allowing for faster corrective action and less impact on the routine.
The calibration certificate shows the average obtained by the instrument after successive measurements) and its uncertainty (variation of measurements). The user must verify that the range of results (average +/- uncertainty) presented in the certificate is contained in the maximum error allowed by the laboratory (usually called tolerance).
In some instruments, this is possible; however, it is not recommended.
Micropipettes/pipettors usually have an internal lock, which can be violated by the user, by forcing the adjustment to volumes above or below the recommended use range.
However, this practice can initiate a process of loss of adjustment and calibration, in addition to loosening or breaking the thread, causing the instrument to dispense wrong volumes. Great care must also be taken with instruments whose values indicated in the volumetric are multiplied by 10 to read the value dispensed.
The Administrator can only be changed upon request by email to Customer Service. After the change, the lab receives an email confirming the change.
When entering the Online System link, a small window should open for you to enter the laboratory number, login (user) and password. However, some computers are configured with anti-popup or the internet service provider itself does not allow opening this window. In this case, it is necessary to disable the anti-popup on the computer or ask the internet service provider to disable it. In some cases, the anti-popup is on the Internet Explorer bar in (View / Toolbar).
In this case, it is necessary to click on (Online System) and (I forgot my password). In the pop-up that will open, enter the laboratory number and your email. The system will send your password to your email.
If you do not know your registered email address, ask the Online System Administrator to verify, or contact ControlLab.
Your laboratory probably uses a service to control access to websites on the internet. In this case, it is possible that access to the ControlLab website was not allowed, or the permission was partial (some parts of the website are not yet enabled). Therefore, when trying to access it, the message "page not found" appears. The ideal is to ask the control service manager for full access to the Controllab website. It is interesting to register, at this moment, all possible addresses of ControlLab: www.controllab.com.br; https://www.controllab.com.br; www.control-lab.com.br; .
The first possibility is that the registered email is out of date or has been registered wrong. If you are already a user of the online system, you can update your email in "user registration" in the system menu. If you are a new user, contact ControlLab Customer Service.
Another possibility is that the user has disabled the receipt of emails in his registration. In this case, a warning about “receiving suspended notices” must have appeared in the online system to alert you. It is important to access the user registration area in the online system to re-enable receipt.
It may also be that your provider has anti-spam, just like the providers Terra and UOL. The anti-spam filter system, when activated on computers, makes it difficult for some users to receive messages by email. Part of the messages sent by ControlLab are automatic and, therefore, can be interpreted as spam.
Who activates the anti-spam service is the user himself. So, to continue receiving our messages, just authorize the domain controllab.com.br. For example, if your provider is UOL, just click on (anti-spam - domain) and make the authorization.
The Illustrated Questionnaires are made available to users of proficiency testing. Users of the Clinical Proficiency and Hemotherapy tests have access to 12 themes per year and users of the Veterinary Proficiency Testing to 4 annual themes.
All users enrolled in these programs have access to the questionnaires, but only one result can be reported by the laboratory. For this reason and depending on the theme, the laboratories distribute it among their professionals, report the consensus option and discuss the evaluation with their team.
The themes are divided into technicians (bacteriology, hematology, immunohematology, molecular biology etc.) and management (quality control, waste management, validation of methods etc.), with the purpose of addressing current issues. A large team of advisors is invited to prepare the questionnaires, according to the area of ??knowledge of each one. The purpose is to promote the recycling of knowledge. For this reason, current issues of a practical nature are addressed in the most dynamic and illustrated way possible, with indications of current literatures (whenever possible provided by links).
Questionnaire evaluations are available:
In the Online System - entering Education/Evaluation, it is possible to access, for each questionnaire answered by the laboratory, a summary with the complete questionnaire (questions, user response and feedback), results profile and evaluation and %A), text on the theme, responses to comments.
The user evaluation and this new form of presentation of the results came into use in 2007, with the new educational project that reformulated the old questionnaires and cases as illustrated questionnaires.
