Sedation, analgesia, and delirium management in Portugal: a survey and point prevalence study.

OBJECTIVE: To establish current Portuguese critical care practices regarding analgesia, sedation, and delirium based on a comparison between the activities reported and daily clinical practice.

METHODS: A national survey was conducted among physicians invited to report their practice toward analgesia, sedation, and delirium in intensive care units. A point prevalence study was performed to analyze daily practices.

RESULTS: A total of 117 physicians answered the survey, and 192 patients were included in the point prevalence study. Survey and point prevalence studies reflect a high sedation assessment (92%; 88.5%), with the Richmond Agitated Sedation Scale being the most reported and used scale (41.7%; 58.2%) and propofol being the most reported and used medication (91.4%; 58.6%). Midazolam prescribing was reported by 68.4% of responders, but a point prevalence study revealed a use of 27.6%.Although 46.4% of responders reported oversedation, this was actually documented in 32% of the patients. The survey reports the daily assessment of pain (92%) using standardized scales (71%). The same was identified in the point prevalence study, with 91.1% of analgesia assessment mainly with the Behavioral Pain Scale. In the survey, opioids were reported as the first analgesic. In clinical practice, acetaminophen was the first option (34.6%), followed by opioids. Delirium assessment was reported by 70% of physicians but was performed in less than 10% of the patients.

CONCLUSION: The results from the survey did not accurately reflect the common practices in Portuguese intensive care units, as reported in the point prevalence study. Efforts should be made specifically to avoid oversedation and to promote delirium assessment.
