Delirium in ICU Patients: Barriers and Facilitators to Effective Care

Strategic Insights -

A recent study has shed light on the challenges facing healthcare professionals in identifying and managing delirium in critically ill patients. Delirium, a common condition in ICU patients, is associated with increased mortality and long-term cognitive impairment. Researchers at the University of Bristol explored the barriers and facilitators to the use of existing ICU delirium identification tools and implementation of care protocols.

Key Takeaways:

  • The study found that 21 ICU healthcare professionals from 20 hospitals were interviewed, including consultants, nurses, advanced critical care practitioners, and allied health professionals.
  • Five major barriers to effective delirium care emerged: lack of prioritisation, lack of structured ICU delirium care protocols, inability to implement interventions due to physical space constraints and/or lack of resources, loss of experienced staff, and changes in ICU nursing culture.
  • Facilitators included the presence of clear protocols, continued staff training, increased awareness, delirium champions, post-ICU follow-up clinics, family engagement, effective communication, and the use of digital prompts as a component of mandatory electronic documentation.
  • Healthcare professionals highlighted the need for protocol-driven care, enhanced training and awareness, and the inclusion of families in care processes.

Statistics:

  • 21 ICU healthcare professionals were interviewed for the study.
  • The study found that 9 consultants, 8 nurses, 2 advanced critical care practitioners, and 2 allied health professionals were interviewed.
  • 5 major barriers to effective delirium care were identified, including lack of prioritisation and lack of structured ICU delirium care protocols.
  • 7 facilitators to effective delirium care were identified, including clear protocols, continued staff training, and family engagement.
