[Evaluation of practices through simulation: Implementation of Horror Week in a cytotoxic preparation unit].

Objectives: The objective of this work is to describe the interest of developing a simulation for the evaluation and improvement of practices through the realization of a horror week in a cytotoxic preparation unit.

Methods: The simulation was divided into five days, each corresponding to a step in the cytotoxic circuit. Five errors per day were produced and presented to the team in a dedicated room. An observation form was used to collect the errors identified by each person. A satisfaction questionnaire was distributed and a collective debriefing took place remotely.

Results: The average number of errors identified per day was 3.8. The least common errors were reversal of patient height and weight, overloading of the sterilization basket, failure to follow dressing rules in the controlled area, absence of the temperature-monitoring disk, and absence of an opaque bag for photosensitive chemotherapy. The perceived level of difficulty was 3.33/5 and the organization was satisfactory to all participants.

Conclusions: Horror Week achieved its objectives by raising awareness among professionals of the risks of the chemotherapy circuit. The errors that were found to be the least significant allowed us to develop priority areas for ongoing training for our unit.
