Implementing the Richmond Agitation-Sedation Scale in a respiratory critical care unit: a best practice implementation project.

Abstract

Adequate sedation can lead to patient-ventilator synchrony, facilitation of treatment, and decreased physical and psychological discomfort for patients with respiratory failure in the intensive care unit (ICU). The Richmond Agitation-Sedation Scale (RASS) is considered to be the most appropriate tool in sedation assessment. This aim of this project was to implement evidence-based recommendations for sedation assessment using the RASS in mechanically ventilated patients in the ICU. This implementation project was conducted in an ICU at a tertiary medical center in Taiwan. Using the JBI Practical Application of Clinical Evidence System software, a baseline audit was conducted in the ICU, followed by an identification of barriers of RASS assessment and an implementation of management of strategies to improve the consistency of sedation assessment. Results of the baseline audit showed that four of the six selected criteria had 0% compliance. Following the implementation of the strategies, which included education, visual management and development of a "RASS Reminder Card", there was an improvement in all the criteria audited, with each criterion achieving 83-100% of compliance. The project successfully improved the implementation of RASS assessment in the respiratory ICU. Following the development and implementation of evidence-based resources, a high level of compliance was achieved for nurses using the RASS in the ICU to assess sedation in patients with a ventilator.
