HD in patients with hip fractures.

Study	, mean age in years	Diagnosis of delirium	Subtyping	Summary of findings
van Munster et al., 2009 [32]	62,; 84.8	CAM, DOS, DRS-R-98	DSI	Delirium subtype was specified in 34 delirious patients. 11.8% HD; No significant difference in S100B protein or Neuron Specific Enolase levels was seen between delirium subtypes. There were no differences in cognitive impairment among different subtype delirious patients
Lundström et al., 2012 [33]	129,; 86	MMSE, OBS scale	OBS scale	22% HD in dementia patients; 41% HD in nondementia patients; No differences in mortality between delirium subtypes during hospitalization and at one-year follow-up
Slor et al., 2013 [34]	42,; 87.6 for HD patients	CAM, MMSE	DRS-R-98	16.7% predominantly HD. 36.7% had a variable profile. Delirium subtype at these assessments was hypoactive in 25% of cases (28 out of 112 assessments)
Slor et al., 2014 [35]	46,; 86.3	CAM, MMSΕ	DMSS, DRS-R-98	23.9% HD
