Field trials quality assurance

In the author s experience, field residue trials can be conducted in Latin America under complete compliance with all ERA guidelines and recommendations. More time does need to be spent in planning and preparation to ensure that the personnel involved in the testing have been trained in GLP and that this training, as well as the compliance of equipment, storage and archival sites, standard operating procedures (SOPs), and quality assurance (QA) audits, are properly documented. 

When a protocol is issued, the study is put on the Master Schedule. The Master Schedule is a computer-generated document that can be formatted and sorted to accommodate the needs of various participants in the study as well as the Quality Assurance Section. It contains the protocol number, the trial numbers, the study title, the proposed start and finish dates of field and analytical segments of the study, the proposed reporting date, the names of field participants, the name of the study director, and other information that may be useful to the users of the master schedule.

Records are kept of when a sample was collected, the method of collection, who collected the sample, what the elapsed time was between harvest and freezing, the conditions under which it was stored, how it was shipped to the laboratory, and when it was shipped. When a sample arrives at the laboratory, the condition of the sample is checked and recorded. Then the information on the sample bag (sample number, application rate, preharvest interval, etc.) is compared to the trial information sheets which are submitted along with the samples. Any omissions or discrepancies are corrected at that time. If there is an omission or discrepancy that cannot be easily corrected by a telephone call from the sample processing laboratory to the field scientist, the study director is notified. The study director must make the decision about the validity of the sample and put a note in the data file explaining how the problem was corrected or that the problem could not be corrected and the trial is to be abandoned. If the trial is dropped, Quality Assurance is notified, the trial is deleted from the active Master Schedule, and an explanation is put in the study file. 

Proper organization of the study management is necessary for an effective quality assurance program. Each study is directed by the scientist who will write the final report but may be assisted by a coordinator. The coordinator also usually assists the study director in designing the study. All questions about the trial during its conduct in the field go to the study director or the coordinator.

Quality assurance activities actually begin early in the drug development process—in the analytical phase. United States requirements5 are established as early as non-clinical laboratory studies. At this early phase, the audit program concentrates on in vivo and in vitro experiments, focusing on early drug entities. These drug entities are tested under laboratory conditions to determine their potential safety risk. At this phase, human subjects (e.g., clinical studies) or field trials in animals are not involved. 

Nonclinical Quality Assurance. Quality assurance unit means any person or organizational element, except the study director, designated by testing facility management to perform the duties relating to quality assurance of nonclinical laboratory studies. Nonclinical laboratory study means in vivo or in vitro experiments in which test articles are studied prospectively in test systems under laboratory conditions to determine their safety. The term does not include studies utilizing human subjects or clinical studies or field trials in animals. The term does not include basic exploratory studies carried out to determine whether a test article has any potential utility or to determine physical or chemical characteristics of a test article.
