Abstract
This retrospective study sought to investigate issues related to the safety of psychopharmacological agents used by acutely medically ill hospitalized older adults. It explored if there were any associations between commonly prescribed psychiatric medications that medically ill hospitalized older adults received and adverse events. It also sought to compare the safety of antidepressants, sedative/hypnotics, and antipsychotics, when used as a standing (on a preset schedule) and as needed pro re nata (PRN) basis. The study found that psychopharmacological agents are frequently prescribed for medically ill hospitalized older adults. No statistically significant difference was found as far as safety was concerned. The number of PRN medications that were used, and the total number of medications was associated with increased risk of transfer within the hospital to a higher level of care or transfer upon discharge to long-term-care/rehabilitation or hospice. Overall, the use of psychopharmacological agents did not appear to be related to serious adverse events.
