Background:
Delirium in the intensive care unit (ICU) has received more attention in the past decade. Early detection, prevention and treatment of delirium are important, and the most commonly used tool for delirium assessment is the Confusion Assessment Method for the ICU (CAM-ICU).
Aim:
The aim of this study was to identify nurses' and physicians' perceived professional barriers to using the CAM-ICU in Danish ICUs.
Methods:
This study uses a qualitative explorative multicentre design using focus groups and a semi-structured interview guide. Five focus groups with nurses (n = 20) and four with physicians (n = 14) were conducted. Strategic sampling was used to include participants with varying CAM-ICU experience at units, with variable implementation of the tool.
Results:
Using a hermeneutical approach, three main themes and nine sub-themes emerged. The main themes were (1) Professional role issues: CAM-ICU screening affected nursing care, clinical judgment and professional integrity; (2) Instrument reliability: nurses and physicians expressed concerns about CAM-ICU assessment in non-sedated patients, patients with multi-organ failure or patients influenced by residual sedatives/opioids; and (3) Clinical consequence: after CAM-ICU assessment, physicians lacked evidence-based treatment options, and nurses lacked physician acknowledgment and guidelines for disclosing CAM-ICU results to patients.
Conclusion:
In this study, ICU nurses and physicians raised a number of concerns regarding the use of the CAM-ICU for delirium detection. It might be necessary to revalidate the instrument as ICU care has changed in recent years, with lighter sedation and early mobilization of patients. We recommend that nurses and physicians receive more training in the use of the CAM-ICU to address some of the issues identified in our study.
Relevance To Clinical Practice:
There is a need for ongoing training and clearer guidelines on how to proceed with the delirium screening of non-sedated patients.
