Changes in sedation management in German intensive care units between 2002 and 2006: a national follow-up survey

BACKGROUND The aim of this study, conducted in 2006, was to find out whether changes in sedation management in German intensive care units took place in comparison with our survey from 2002. METHODS We conducted a follow-up survey with a descriptive and comparative cross-sectional multi-center design. A postal survey was sent between January and May 2006, up to four times, to the same 269 hospitals that participated in our first survey in 2002. The same questionnaire as in 2002 was used with a few additional questions. RESULTS Two hundred fourteen (82%) hospitals replied. Sixty-seven percent of the hospitals carried out changes in sedation management since the 2002 survey. Reasons for changes were published literature (46%), national guidelines (29%), and scientific lectures (32%). Sedation protocols (8% versus 52%) and a sedation scale (21% versus 46%) were used significantly more frequently. During sedation periods of up to 24 hours, significantly less midazolam was used (46% versus 35%). In comparison to 2002, sufentanil and epidural analgesia were used much more frequently in all phases of sedation, and fentanyl more rarely. For periods of greater than 72 hours, remifentanil was used more often. A daily sedation break was introduced by 34% of the hospitals, and a pain scale by 21%. CONCLUSION The increased implementation of protocols and scoring systems for the measurement of sedation depth and analgesia, a daily sedation break, and the use of more short-acting analgesics and sedatives account for more patient-oriented analgesia and sedation in 2006 compared with 2002.
