Background. Guidelines for sedation, ventilator weaning, and delirium screening are helpful to avoid too deep sedation and to identify signs of delirium in the intensive care unit (ICU). Methods. National ICU registry members () were surveyed regarding use of scoring instruments and guidelines for sedation and ventilator weaning, choice of drugs, and daily sedation interruption practices. Results were merged with registry data on ventilator time and length of stay for ICU patients ventilated >24 hours (7.075 ICU stays). Results. Eighty-five percent of the 33 responding ICUs used sedation scales and 39% and 55% had sedation and weaning protocols, respectively. An association was found between using protocols and longer mean ventilator time and mean length of ICU stay. Thirty three percent (11/33) practiced daily sedation interruption. Regular delirium assessment was associated with significantly shorter mean ventilator time and mean length of ICU stay but used by few. Conclusion. More ICUs had guidelines for weaning than for sedation. The ventilator time and length of ICU stay compared well with other studies. Although having guidelines was associated with longer ventilator time and ICU stay, the differences were rather small. Daily sedation interruption was seldom used. Few units used delirium scoring instruments.
