Background: Potentially inappropriate medication (PIM) use in the elderly is associated with increased risk of adverse drug reactions (ADRs), but there is limited information regarding PIM use in the intensive care unit (ICU) setting.
Objective: The aim of the study is to describe the prevalence and factors associated with the use of PIM and the occurrence of PIM-related adverse reactions in the critically ill elderly.
Methods: This study enrolled all critically ill older adults (60 years or more) admitted to medical or cardiovascular ICUs between January and December 2013, in a large tertiary teaching hospital.
