Procedure performance evaluation

Clearly defining the conditions, actions, and standards ensures that the trainee performance evaluation will be cbnsistent and accurate. An example of a procedure performance evaluation form is included in Appendix D, Procedure Performance Evaluation. 

This appendix includes a sample procedure performance evaluation document which can be used by an evaluator to evaluate a trainee s performance of a procedure. This document, when used in conjunction with an approved, up to date procedure, becomes a performance evaluation tool. The items listed on the second page should be customized to your faciht/s training program requirements. 

How will you verify that a trainee can perform a task (as written in a procedure) safely and correctly You can use the procedure performance evaluation with the procedure while observing the trainee perform or simulate the procedure. The procedure is the criteria for safe and correct performance of the task, and the procedure performance evaluation document is the guideline for the evaluator and the trainee. Upon the completion of the performance evaluation, this document becomes the record of performance.

Annex I inclusion of an a.i. is the result of a harmonized evaluation and decisionmaking procedure, performed on the basis of harmonized data requirements, as detailed in Annexes II and III to the Directive. 

Beasley et al. developed a panel of immunoassays to monitor DDT, its metabolites, and structurally related compounds, but they found that milk has a severe effect on the assay performance. They found that when directly utilizing whole milk, color development was completely inhibited. Even when using 1 100 dilutions of whole milk, the assay sensitivity was reduced by 90% (based on the IC50 shift, not simply the dilution factor). A number of procedures were evaluated to eliminate the interferences from the fat-soluble analytes. However, many of the procedures that removed interferences also removed the analytes. Extraction with a mixture of solvents and the use of similarly processed blank milk to prepare the standards ultimately yielded more accurate results. This article demonstrates the difficulties encountered in analyzing lipid-soluble analytes. 

The effectiveness—NTU method is a procedure for evaluating the performance of heat exchangers, which has the advantage that it does not require the evaluation of the mean temperature differences. NTU stands for the Number of Transfer Units, and is analogous with the use of transfer units in mass transfer see Chapter 11. 

DEMULSIFICATION TESTS. Demulsification tests were conducted using standard bottle test procedures to evaluate the relative performance of Thin Film Spreading Agents in coalescing emulsions of formation brine in crude oil under reservoir conditions. 

Make safety investments on a basis of cost and performance. Evaluate each investment (money and time) to ensure that there is a true safety improvement proportional to the investment. If the designer is not careful, changes to the system or new procedures may add complexities that result in a more hazardous situation rather than in an improvement. 

Quantitative CE—MS studies were scarcely reported. " This subject is however of prime importance, particularly for the pharmaceutical industry where the reliability of analytical data is essential. For this reason, method development is generally followed by an evaluation of quantitative performance using an appropriate validation procedure performed in agreement with criteria established by the International Conference on Harmonisation of technical requirements for registration of pharmaceuticals for human use (ICH) and the Food and Drug Administraction (FDA) guidelines, or Societe Franqaise des Sciences et Techniques Pharmaceutiques (SFSTP) commissions. ...

In the second edition, 64 new validation SOPs are added to describe documentation required for sterility assurance, qualification and requalification template reports of major sterile equipments, critical applicable procedures, templates for certification guidelines, media fill procedures, environmental control guidelines, training, and critical environmental performance evaluation procedures. 

While the provision of suitably validated analytical methods is a necessary requirement for ensuring compliance with MRLs, the method alone is not sufficient to ensure creditable analytical measurements. In addition to selecting suitable methods, the analyst must demonstrate that the method is operating under statistical control in the laboratory and is performed to meet performance specifications as required by the analytical problem. This means that all methods should be applied in an environment with appropriate quality assurance procedures and performance evaluation checks. 

Work on the characterization of oil-field emulsions coupled with chemical characterization of commercially available demulsifier formulations has shown that physical processes (temperature, pumping, and dispersed water size distribution) can be at least as important as the chemical effects associated with demulsifiers themselves in determining demulsifier effectiveness [468,469].In fact, there are so many variables involved in industrial demulsification that, to a large degree, demulsifier selection and performance evaluation are still conducted using simple test procedures developed for use in the plant or field. These tests, usually bottle or centrifuge tests, can be good indicators of performance trends, and are usually carried out for selected suites of commercial demulsifier formulations. 

The necessary components of a complete QA/QC program include internal QC criteria that demonstrate acceptable levels of performance, as determined by a QA review (audit). External review of data and procedures is accomplished by the monitoring activities of accreditation organizations such as the Standards Council of Canada (SCC, 2005). This includes laboratory evaluation samples (PT samples, see above) and a periodic (sometimes every 2 years) on-site assessment of all QA/ QC procedures, performed by external assessors from the accrediting organization. 

In recent years much attention has been given to improve methods for pilot plant testing catalysts performance evaluation. A proper simulation of the desactivation mechanisms which occur commercially in a pilot plant procedure is of great importance. 

An alternative method for performance evaluation is to participate in inter-laboratory comparisons, often known as round-robins . Usually this involves sending sub-samples of a selection of appropriate samples to a number of independent laboratories, to be analysed either by a fully specified procedure and technique, or to be analysed by whatever method each laboratory choses. Obviously, these two approaches test different things. The former indicates the precision attainable using a specified procedure, and tests both the adequacy of the specification and the competence of participating laboratories. Only the...

Baumgartner and Hill s decontamination procedure was evaluated on more than 500 different hair samples that were externally contaminated in this laboratory. In the initial phases of this study we used four phosphate washes. In later phases, based upon the comments in Baumgartner and Hill, ° our procedure was modified to use between three and ten phosphate washes. However, in the radioactive tracer experiments we typically perform, it is possible to account for all radioactivity the sample is digested and no radioactivity is lost from any extraction step. Therefore, it is possible to calculate the effect of either three or four phosphate washes on the decontamination of the hair and on the various calculated criteria. No remarkable differences were found between our four-phosphate extraction process and the recalculated values for the equivalent three-phosphate extraction process.
