Patient safety culture and medication safety in European intensive care units: a focus group study

Background: Patients in intensive care units (ICUs) are susceptible to medication errors (MEs) for many reasons, including the complexity and intensity of care. Little is known about patient safety culture, its relationship to medication safety, and ME prevention strategies used in ICUs. This study explored the attitudes of healthcare professionals (HCPs) working in ICUs or within medication safety towards patient safety culture, medication safety, and factors influencing implementation of ME prevention strategies in ICUs across Europe.

Methods: This qualitative study employed focus group discussions; ethical approval was obtained. Invitations to participate were distributed to HCPs working in ICUs or as medication safety officers across Europe. In May 2022, online focus group discussions were conducted. Discussions were transcribed verbatim and analysed. The framework analysis employed was inductive, systematic and transparent, and completed through a collaborative and iterative process.

Results: Three nurses and 11 pharmacists, from seven different countries, participated in three focus group discussions. There was a sense of improvement in blame culture leading to more open culture, although it was not the case for all participants. Blame culture, when present, was thought to be prevalent among more senior ICU staff and hospital managers. Facilitators for improving medication safety included communicating with HCPs and providing feedback on MEs and ME prevention strategies, interprofessional working without hierarchies, and having a 'good' culture and environment. Barriers included lack of engagement of HCPs and their attitudes towards medication safety, and an existing blame culture. Participants reported 25 different ME prevention strategies in use including: assessing knowledge; teaching and training; auditing practice; incident reporting; and involvement of pharmacists.

Conclusions: This study examined the attitudes of HCPs on patient safety culture and medication safety in the ICU setting in Europe and gained their insight into facilitators and barriers to the implementation of ME prevention strategies to improve medication safety.
