[Improvement of the pre-examination phase of medical biology exams at the Henri Mondor University Hospitals: a pilot study].

The medical and university department of biology pathology at Henri Mondor hospital in Créteil has been engaged in an NF EN ISO 15189 accreditation process since 2014. One of the elements of this process concerns the quality of handling of samples and their transportation to laboratories, including the implementation place requires fighting against pre-examination non-conformities, which are the source of many dysfunctions. The pre-examination group has implemented several actions in a targeted care service. Thanks to these, the rate of non-conformities has halved in 18 months. In parallel, a work project targeting student nurses on internship was born to follow up on the results of a statistical study carried out by the pre-examination group on non-conformities. The objective of the project was to include nursing students on internship in a full support course on good sampling practices and pre-analytical non-conformities. This was based on the realization of two knowledge quizzes (before and after training), theoretical training, and visits to several laboratories. This study lasted 10 months with the participation of 37 students. The results showed a marked improvement in knowledge of pre-analytics as well as total satisfaction of all students. Our approach has helped to better understand the needs of laboratories and demonstrates the usefulness of training students in good sampling practices in order to ensure better patient care as well as an improvement in their comfort and well-being.
