Conclusions
The proportions of patients taking any PIMs and/or PPOs were
significantly reduced from acute admission to geriatric rehabilitation
discharge. Neither PIM, nor PPO
use at geriatric rehabilitation discharge were consistently associated
with an increased risk of unplanned readmission and mortality. However,
the number of discharge medications were strongly associated with short
and long-term readmission. The use and number of PPOs that included
vaccine omissions were negatively associated with the longitudinal gains
in IADL scores at 90-days following geriatric rehabilitation discharge.
Interventions toward patient-tailored appropriate (de) prescribing in
geriatric rehabilitation patients are needed, taking the number of
medications, unnecessary and omitted medications into account.
