Why the study?
Are polypharmacy and drug burden index associated with adverse clinical measures such as hospital admission for delirium in hospitalised older people?
Are polypharmacy and drug burden index associated with adverse clinical measures such as hospital admission for delirium in hospitalised older people?
Drug burden index, but not polypharmacy, is associated with an increased risk of hospital admission for delirium in hospitalized older people.
May inform delirium risk stratification in older inpatients; leaves open causal effects and practice change.
In the present study, DBI was associated with an increased risk of hospital admission for delirium only. Polypharmacy was not associated with any of the clinical measures.
