[A check-list in order to optimise the deployment of computerized medicine cabinets in a hospital: An essential support]

In the medication management process, storage methods constitute a step at risk of errors that needs to be secured. As part of an institutional project, computerized medicine cabinets (CMC) have been deployed in our hospital's emergency and intensive care units. In order to meet the requirements of the certification, the deployment of CMC in all care units has been decided. Each deployment includes many steps and involves several trades that must be coordinated. We decided to formalize these steps in the form of a checklist. Two pharmacists listed all the tasks required to install a CMC. They were ordered chronologically, and a person responsible for each step is proposed. All those involved in the installation of CMC in the care units validated the checklist. The checklist is broken down into 13 major steps, from the assessment of the need to the installation of CMC in the care units. Before installation, several months are required, particularly in terms of the delivery time of the CMC. Support and training for the pharmacy technicians and caregivers are essential to ensure the teams enrolment. By better implying and empowering all intervenants, directed by the pharmacist, the checklist provides to dynamise and to frame the CMC deployment. Moreover, it contributes to save time and to improve the management of every ongoing deployments.

[Subcontracting a steam sterilization activity: Impact on surgical instruments]

Subcontracting our institution's sterilization activity induced the implementation of an automated cleaning facility. Following this development, some of the resterilizable stainless steel needle holders started to show abnormal corrosion. Our study goal was to investigate the causes of this corrosion in order to optimize the sterilization circuit. A full sterilization process mapping and Ishikawa diagram enabled us to identify potential causes of corrosion. The needle holders' intrinsic characteristics, like steel quality and manufacturing, were analyzed as well as extrinsic factors such as the influence of preprocessing soaking conditions, steel passivation, water quality and the impact of corrosion inhibitors. Each potential factor of corrosion was tested in real conditions on needle holders' kits. The needle holders steel grade complies with medical standards and the tests showed that passivation and pre-processing conditions were not involved in the occurrence of corrosion, contrary to soaking length and use of softened rinsing water, containing more chloride than reverse osmosis water, and, thus conducive to rust formation. Moreover, corrosion inhibitors were deemed ineffective or incompatible. Due to this analysis, the incidence of corrosion was reduced by switching softened water to osmosis water and by introducing dynamic drying in the automated cleaning process. In addition, this work stresses the importance of minimizing waiting times and auditing the sterilization circuit before any subcontracting. Management Guidelines related to sterilization's outsourcing would probably have helped to limit this episode.
