HD in palliative care.

Study	, mean age in; years	Diagnosis of delirium	Subtyping	Summary of findings
Bruera et al., 2009 [48]	99,; 60	MDAS, MMSE	No specific scale	20% HD; Delirium recall was not significantly different according to subtype (hyperactive versus hypoactive versus mixed)
Godfrey et al., 2010 [49]	25,; 76.5 (HD patients)	DRS-R-98, CTD	New subtyping scheme derived from Meagher	40% HD; HD patients were older than those in each of the other groups
Meagher et al., 2011 [50]	100,; 70.2	DRS-R-98	DMSS	28% HD; HD was associated with a poorer prognosis, regarding survival at 1 month, compared to other subtypes; Transitions into hypoactive subtype were preceded by; increased benzodiazepine dose
Leonard et al., 2011 [51]	100,; 70.3	CAM, DRS-R-98, CTD	DMC	33% HD; Hypoactive and mixed subtypes differed with regard to administrated chlorpromazine-equivalent doses (hypoactive patients received lower doses)
Boettger and Breitbart,; 2011 [52]	100,; 58.3	MDAS	MDAS	53% HD; There were no differences in symptomatology between subtypes
Rainsford et al., 2014 [53]	22,; 70.1	CAM, DRS-R-98	DRS-R-98	50% HD; The treating team failed to recognize 45.5% of those with HD
