Meier 2001.

Methods	Prospective observational cohort study. Follow up to potentially 5 years.
Participants	99 American inpatients with advanced dementia (defined as FAST stage 6d or greater) and an available surrogate decision maker (to make decision on patient's behalf on participating in study). Median age 84 years (range 63‐100). 81% were female, 15 had advanced directives.
Interventions	Tube feeding of which at least 51 patients had a PEG inserted. Since this study was conducted in the USA it is likely that the majority of participants had a gastrostomy or jejunostomy tube as this is usual local practice. 17% admitted to hospital with tube already in place, new tube placed in 50% (51/99), 31% left hospital without a feeding tube. Reason for tube not stated.
Outcomes	In stepwise logistic regression tube feeding was not associated with survival (P = 0.90).
Notes	Limitations: unclear how comparable were demented patients who were tube fed with those that weren't.
