Why was it done?

PN is a high-risk preparation that carries a significant risk of iatrogenesis, making it essential for staff responsible for its prescription, validation, and preparation to be well-trained, and for a reliable quality assurance plan to be in place. Monthly quality indicators include errors by pharmacists during transcription to nutrition software, errors by technicians in tray preparation, and nursing errors during PN preparation. Acceptable monthly error thresholds were set at 2 for transcription, 25 for tray preparation, and 6 for sterile PN preparation. Additional activity indicators, such as the number of PN preparations per month, episode duration, and reasons for suspension, were also analyzed.

What was done?

A training program centered on audiovisual resources related to parenteral nutrition (PN) procedures was implemented in a tertiary hospital after a quality assessment within the PN department revealed a decline in certain indicators between 2020 and 2022. A shared folder with video tutorials covering various processes was made available to pharmacy staff, mainly intended for nursing staff and pharmacy technicians, who typically have high turnover rates between departments.

How was it done?

The indicators showed a steady increase in PN preparations, rising from 411±74 per month in 2020 to 475±51 in 2023, with a record of 634 preparations in March 2024. Notably, 18.1% of episodes in 2023 lasted over two weeks, partly due to the underutilization of home PN and a lack of hospital beds despite increased outpatient activity. Errors in tray preparation increased from 2020 to 2022, peaking in 2021. This coincided with high staff turnover and an increased workload. In response, the implementation of video tutorial training for rotating staff was introduced in 2022.

What has been achieved?

This initiative reduced tray preparation errors, which decreased to an average of 12±4.9 between January 2023 and March 2024.

What next?

These measures could be adapted and implemented in other departments within the pharmacy service. Regarding PN, we are now aiming to optimize the workload by promoting home PN, and implementing semi-automated systems such as barcodes and gravimetric control, which are also recommended to improve safety and traceability.
