Abstract Background Several efforts have been made to assure and to improve the quality of procedural sedation and analgesia (PSA) performed by emergency physicians (EPs) in The Netherlands.

Results The respondents (n = 191) represented 84.6% hospitals with EPs and 41.3% of all EPs in The Netherlands. Nearly all EPs (97.8%) performed PSA in adult patients compared to only 59.1% who performed PSA ...
