Shamliyan TA, Kane RL. J Patient Saf. 2016;12:89-107.

Prior studies have shown that older patients are particularly vulnerable to medication errors. This cohort study documents a marked increase in both hospitalizations due to adverse drug events and in Medicare patients between 2000 and 2008. During that time frame, the incidence of in-hospital adverse drug events and the severity of harm experienced by patients rose as well.
