Survey among critical care nurses and physicians about delirium management.

BACKGROUND

Delirium is a serious complication in patients in intensive care units. Previous surveys on delirium management in daily practice showed low adherence to published guidelines.

AIM

To evaluate delirium management in nurses and physicians working in intensive care units in German-speaking countries and to identify related differences between nurses and physicians.

DESIGN

The study used an open online survey with multiple-choice responses.

METHODS

An invitation for participation was spread via journals and electronic resources using a snowball system. Apart from recording socio-demographical characteristics, the survey collected data on delirium assessment, delirium-related processes, non-pharmacological prevention and treatment and barriers for implementation. Differences between nurses and physicians were tested by Fisher's exact test with sequential Bonferroni correction.

RESULTS

The survey was conducted in autumn 2016, and 559 clinicians participated. More nurses than physicians reported screening for delirium. The majority of clinicians reported screening for delirium when this was suspected; more than 50% used validated instruments. Half of the clinicians had delirium-related structures implemented, such as two thirds reporting delirium-related processes. Most cited barriers were lack of time and missing knowledge about delirium and its assessment. With significant difference, physicians recommended more than nurses early removal of catheters and daily interprofessional goals for patients.

CONCLUSION

In German-speaking countries, assessment of delirium needs further improvement, leading to accurate assessment. Delirium-related structures and processes appear to be implemented widely, with only a few differences between nurses and physicians.

RELEVANCE TO CLINICAL PRACTICE

Nurses and physicians in this survey reported similar perceptions and attitudes towards management of delirium. Both professions need more knowledge and inter-professional training on when and how to use validated assessment instruments.
