Nurses' and physicians' sedation practices in Danish ICUs in 2003 A national survey.

OBJECTIVE

The aim of the study was to describe and compare physicians' and nurses' estimated use of sedatives and analgesics in patients requiring mechanical ventilation in Danish Intensive Care Units (ICUs) in 2003.

DESIGN

Questionnaires were mailed in January 2003 to all Danish ICUs providing mechanical ventilation (n = 48). One physician and one nurse at each site were included in the study.

RESULTS

Thirty-nine questionnaires were returned by physicians (response rate 81%) and 43 by the nurses (response rate 90%). Physicians and nurses agreed that sedation related decisions are predominately made during rounds and that most decisions are made by physicians and nurses collaboratively. Only 9% of the nurses and 23% of the physicians reported using a written protocol for sedation, while 30% of the nurses and 44% of the physicians reported the use of sedation scoring systems. The study generally supported the hypothesis, that nurses' and physicians' would respond similarly, but there were, however, significant variations, regarding formal sedation practices.

CONCLUSIONS

Sedation decisions are made collaboratively by nurses and physicians, while sedation protocols and scoring systems are still not systematically implemented in Danish ICUs. The most common drugs for sedation of the mechanically ventilated patient are propofol and fentanyl by continuous infusion. It is recommended that the ICUs collaborate on developing evidence-based standards for sedation and that clinical databases are introduced, which may be used to assess the efficacy of such standards.
