The studies were heterogeneous in design and size (N=25 to 809,512). Mean age ranged from 57 to 84 years. Four studies reported only overall DS documentation and HAS coding in whole hospital or healthcare databases. Twenty studies used additional delirium ascertainment methods (e.g.\u00a0chart review) in smaller patient subsets. Studies reported either DS figures only (N=8), HAS figures only (N=11), or both (N=5). Documentation rates in DS ranged from 0.1% to 64%. Coding rates in HAS ranged from 1.5% to 49%. Some studies explored the impact of race, and nurse versus physician practice. No significant differences were reported for race; one study reported that nurses showed higher documentation rates in DS relative to physicians. Most studies (N=22) had medium to high RoB.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"conclusion\">\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Delirium is a common and serious medical emergency, yet studies show considerable under-documentation and under-coding in healthcare systems.
