Background:
Atypical antipsychotics (AAP) have been associated with reduced duration of
delirium in the intensive care setting. However, long-term use of these
drugs is associated with significant adverse events, including increased
all-cause mortality in the elderly. Inappropriate continuation of AAPs after
discharge from the intensive care unit (ICU) is worrisome and needs to be
addressed.
The aim of this work was to assess the prevalence of continuation of AAPs
after hospital discharge and evaluate the associated risk factors.
Method:
This was a single-center retrospective chart analysis in the setting of adult
ICUs at a tertiary care academic medical center. It involved all adult
patients admitted to the ICU and initiated on AAPs from January 2012 to
December 2014. The measurements were: (1) prevalence of ICU-initiated AAP
continuation following hospital discharge, (2) risk factors associated with
continuation of AAPs following hospital discharge, and (3) risk of
continuation of AAPs in patients ⩾65 years of age.
Results:
A total of 55% of ICU patients initiated on AAPs were discharged from the
hospital with a prescription for continued AAP therapy. Male sex and
discharge location were highly associated with continuation upon discharge.
Older patients (⩾65 years of age) were not at a higher risk of being
continued on these drugs after discharge.
Conclusion:
Male sex and discharge to a healthcare facility were associated with a higher
rate of continuation. Research into practical methods to reduce their
continuation upon discharge should be performed to mitigate the long-term
risks of AAP administration.
